For example, the cyclone early warning systems is a policy intervention which aims to generate and communicate information to the people about the possible cyclone occurrence, so that people (the exposed units) could respond (change behaviour) in terms of evacuating the risk prone areas and/or take refuge in a cyclone shelter etc. In this paper, using the mental models approach, we identify the factors that affect the perceptual and evaluative processes underlying the ‘warning-response’ process i.e. evacuation behaviour of the exposed units once they have received the cyclone warning. An understanding of such factors would help improve policy response like the cyclone warning systems, which were set up to reduce the threat to life due to cyclones. 1. Introduction Climate change is expected to manifest as changes in nature, frequency and intensity of climate variability and extremes (Smit et. al., 2001). Extreme weather events like severe tropical cyclones have an impact on life, property and livelihoods of communities affected by these extreme weather events. The extent to which socio-economic system are vulnerable to impacts of climate hazards is mediated by two concepts – exposure and adaptive capacity. Exposure is the socio-economic components, including human and manufactured capital as well as natural ecosystems that are exposed to climate risk. Adaptive capacity is the ability of the exposed units to respond positively to environmental change with a view to reducing impacts. While there are opportunities for reducing exposure for example through resettlement, in many countries these opportunities are limited. Therefore ability/capacity of the exposed units (individuals, households, communities) to manage climate and other risks they face determines to a large extent, the vulnerability of the exposed units to the impacts of climate hazards they experience. Enhancing the adaptive capacity would therefore ideally be the aim of policy related to reduction of vulnerability due to climate hazards. Adger et al (2003) define adaptive capacity as the potential or capability of a system to adjust, via changes in its characteristics or behaviour, so as to cope better with existing climate variability, or with changes in variability and mean climatic conditions. Changes in the characteristics and behaviour of systems require that the units of the system are able to perceive the risk (need for change in behaviour), formulate a response and then implement the response with the view to reducing climate risk. Hence, for this study we adopt Patwardhan et al’s (2003) definition of adaptive capacity, where adaptive capacity is defined as the ability of the exposed units to perceive, formulate a response and implement response to climate risk, with a view to reducing impacts. The exposed system or unit has some inherent capacity to perceive risk and formulate and implement response to reduce that risk. But often it is the common day to day hazards such as auto-accidents, conventional pollutants and other economic, health and safety risks of immediate concern that preoccupy the decision-making of the exposed units (Morgan et al, 2002). The risk from relatively infrequent hazards (such as cyclones) or less-known hazards (such as climate change) receive limited attention from people until they are directly affected by the consequences of these hazards or until their attention is directed to such hazards through the process of communication about the risk from the hazard. From a policy perspective, it would be prudent to direct the attention of the exposed units to relatively infrequent or less-known hazards through a risk communication program, so that the exposed units are better prepared to respond to the risk. This class of policy intervention is broadly termed as ‘risk communication’. In the climate context, the risk communication can be for two broad categories of hazard – one is the when the threat is from a relatively rapid onset hazard agent (e.g., severe storms, riverine floods etc.); and second, when risks are developing slowly over time (e.g., global climate change). Empirical research has demonstrated that risk communication processes are qualitatively quite different for these two types of events (Nigg, 1993). The focus of this paper is relatively rapid onset hazard, which requires a short-term forecast, and communication of danger. Specifically, tropical cyclones experienced in the East coast of India provide the context for this study. Every year the Indian coastline experiences cyclones of differing severities – varying from depressions to severe storms. An analysis of all the cyclones that arose in the Bay of Bengal and the Arabian Sea from 1877 to 1990 (IMD, 1996) shows that on an average 8 cyclones crossed the Indian coastline per year with the majority making landfall on the East coast of India, which mainly comprises of the four states of West Bengal, Orissa, Andhra Pradesh and Tamil Nadu. A cyclone causes considerable damage to human life and property in its wake as is evident from numerous reports on disasters such as India Disasters Report (Oxford, 2000), World Disasters Report (IFRCRCS, 2001) by International Federation of Red Cross and Red Crescent Societies and media reports. The cyclone early warning systems were set up, as a policy measure to reduce human mortality due to cyclones. It aims to generate and communicate information about the possible cyclone occurrence to those who need it so as to facilitate good decisions and timely response by the people in danger. The target group’s response to the warning information may or may not be in accordance with the desired response. In fact anecdotal evidence suggest that many a times the cyclone warning message is not able to generate the desired response from the target audience of the warning. This may be because often there is a tendency on part of warning generators and disseminators to assume that the public response to warning is based on a stimulus-response model of behaviour i.e. if people hear the message, they will take the appropriate and suggested actions (Nigg, 1993). Public reaction to warnings of impending disaster is not well characterized by a stimulus-response model (Mileti, 1995). The cyclone warning systems aimed at generating a specific adaptive response (evacuation) interact with exposed unit’s perception of the cyclone risk and the proposed risk reducing measure (evacuation) the policy is proposing. Therefore understanding the factors affecting the risk perception and evaluation underlying the responses of exposed units would provide insights about appropriate points of policy intervention for enhancing the adaptive response by the exposed units. Whether the exposed unit actually evacuates or not is also linked to the availability of resources to respond or other factors, for instance the exposed unit may want to/ intend to evacuate his/her home but may not have the means of transportation or money to evacuate. Or an exposed unit may have the means to evacuate and also the willingness to evacuate but other factors such as being sick or infirm might hinder the evacuation response. Therefore it is not the actual observed response that is of interest here. It is the ‘willingness’ to respond or the contingent response that is of interest in this study. ‘Response’ in this study would refer to this willingness to respond and not the actual observed response. The objective of this study therefore is to identify the factors affecting the perceptual and evaluative processes underlying the ‘warning-response’ process i.e. willingness to evacuate by the exposed units once they have received the cyclone warning. The adaptation to climate change literature does not have any studies to draw upon for addressing the research objective of this study. But because the adaptation and adaptive capacity is being studied in the context of extreme weather event i.e. tropical cyclones, the natural hazards literature (also known as the disasters literature) would be a rich source to draw upon. Section 3 gives a brief review of the relevant literature from the disasters and natural hazards discipline. But before that section 2 presents an overview of the path through which warning flows before it reaches the target audience at the local level. The research approach and methodology used in this study are discussed in section 4. Section 5 presents the analysis and results of the study and section 6 discusses the observations and directions for future work. 2. The path for flow of cyclone warning Figure 1 presents a visual representation of the entire path that the warning information flows through before it reaches the target audience. A cyclone warning system can be classified into two sub-systems – detection and monitoring sub-system and the dissemination sub-system. Figure 1 does not include the information on the detection and monitoring sub-system i.e. the entire network of observatories, radars and satellites through which the cyclones are monitored before the warning is issued. Figure 1 only depicts the dissemination subsystem. Even in the dissemination sub-system only those components of the cyclone warning system are depicted and described that are involved in the dissemination of cyclone warning to the local people in the area likely to be affected by an impending cyclone. It does not include the other departments such as railways, irrigation, the armed forces etc. which also receive the warning for taking precautionary measure. These recipients are not included in this figure as they are not involved in the warning dissemination to the local public likely to be affected. A flowchart that would include all aspects of detection, monitoring and dissemination of the warning would be a part of another study.

The Cyclone Warning Division at IMD, New Delhi coordinates with the Area Cyclone Warning Centres (ACWCs) at Calcutta, Chennai and Mumbai, and Cyclone Warning Centres (CWCs) at Bhubaneswar, Visakhapatnam and Ahmedabad and the forecasting division at Pune, for detection and monitoring of cyclones and when required takes the decision to issue cyclone warning. Once the decision for issuing a cyclone warning has been taken by IMD New Delhi, it is notified to the ACWCs and the CWCs and the secretary of the concerned state. The actual cyclone warning bulletin is issued by the concerned ACWC and the CWC for that state. The ACWC and the CWC send warning messages to the state chief secretary, district collectors of the districts likely to be affected by the cyclone, port officials, fisheries officials, superintendent of police, the media (local dailies and national newspapers, All India Radio and local radio stations, Local television stations and the national television stations) and to other about 140 officials of departments such as railways, irrigation, armed forces etc. (which are not depicted in figure 1). ACWC also send the warning directly to the Mandal Revenue Office (mandal is a sub-district administrative unit) through a specially designed Cyclone Warning Dissemination System which works via the INSAT satellite provides area-specific service in local language even when there is a failure of conventional communication channels. The main drawback with this system is that the analogue device that would receive the warning at the mandal office works on a battery and if there has been carelessness about keeping the battery charged, the receiving device would not work. Based on the intensity of the cyclone in the warning, the port officials hoist the appropriate warning signals during the day and warning lights in the night for the ships and the fishermen on the seas. The fisheries officials communicate the warning by sending messengers to the fishermen dwellings. The responsibility of alerting the general public about the cyclone and the evacuation of the people from the danger zones, lies largely with the district collector (DC) and the mandal revenue officer (MRO). The DC and his team (which consists of the joint collector, the district revenue officer etc.) pass the warning message to the MROs and the block development officer (BDO) of the coastal mandals and other mandals likely to be affected by the cyclone. The DC also keeps the police officials informed to render necessary services in case of emergency. The MRO after receiving the warning sends copies of the telegrams/wireless messages to various local officials such as the the BDO, munsif magistrate, sub-registrar, primary health center officer, taluks medical officer, roads and building engineer, public works department section officer, assistant engineer of floods and the police circle inspector (the police circle inspector also receives the cyclone warning from the superintendent of police). The MRO sets up a round the clock control room in his office. He arranges microphones for public announcement in the town and if possible to other roadside villages. He orders the closure of schools, colleges and cinema theatres and school and college buildings are often used as relief centers for people who have been evacuated from the coastal villages. The MRO, sends instructions to the Revenue inspectors through, telephones, messenger, telegrams who further pass on the warning to the village secretaries. These village officials announce the cyclone warning in the village either through beating drums or by door to door visits. The MRO is also expected to visit the most vulnerable places by a vehicle to caution the general public and officials so as to facilitate timely evacuations.. Similarly the BDO is expected to inform the village development officers and through them alert the people in their jurisdiction. In addition the media also plays its role in disseminating the cyclone warning to the public. 3. Insights from literature Disasters and risk communication literature provide an extensive study of the warningresponse process. The general questions that researchers have attempted to answer are how people decide whether to respond to disaster warnings and then how they decide what to do (Nigg, 1993). The fundamental process underlying the warning-response issue is the risk assessment by the unit of analysis (individual in this case). The social and psychological disciplines have provided the theoretical concepts and models to structure these empirical investigations. Though there are studies by authors such as Mileti and Fitzpatrick(1991), Renn (1992), Rohrmann(2000) that present a framework or a model to explain the warning-response process, all these studies make it clear that warning-response process is embedded in a social context and issuing warnings that will be taken seriously and acted upon is far from an easy process (Tierney, 1993). Most of the studies in this area focused on selected factors to explain the warning response process. Sorenson (1993) (cited in Nigg, 1993) did a review of such studies and identified the factors that affect the warning-response process and also indicated the extent to which empirical evidence exists to substantiate the importance of these factors. These are presented in Table 1. Table1: Major factors co-varying with warning response Factor Direction: As Level of empirical factor increases support response….

Based on the literature, figure 1 presents a conceptual framework listing the main elements of the warning response process and the factors affecting the process. This framework is not a model for the warning-response process as all the causal links and feedback loops are not defined in the framework. Rather, it is a convenient way of visually presenting the elements pf the warning-response process and the major factors affecting this process. Warning-response process: People who receive warnings typically go through a social psychological process to form personal definitions about the risk they face and ideas about what to do before they take a protective action. Mileti (1995) divides the process into several phases: (1) hearing a warning (2) forming a personal understanding of what was meant by the warning (3) confirming the warning (4) developing a level of belief in the risk information conveyed in the warning (5) personalizing the risk or perceiving to be someone else's problem (6) deciding what if anything to do and responding in ways thought to be appropriate for the risk personally faced. The warning-response process is affected by the characteristics of the warning system, message and the senders of the warning message; and by the characteristics of the receivers of the warning and the situational context of the receivers. Warning system/ “sender” characteristics Warning-response process Warning message Message Content * Severity * Likely time * Location *Uncertainty of occurrence * Action to be taken Hear Situational / “receiver” characteristics Environmental cues * visibility of hazard Pre-warning perceptions Exposure conditions Understand Social influence Message Context * Source * Channel * Language * Frequency * Timing Confirm Believe Message attributes Sociodemographic characteristics * Resources *Gender * Age *Socioeconomic class *Ethnicity *Education level Personalize *Consistency * Accuracy * Clarity * Specificity Response Psychological characteristics * Cognitive abilities *Personality *Attitudes Figure 2: A conceptual framework of the warning response process and the factors affecting the process The warning system or “sender” characteristics: The factors related to warning system or sender characteristics can be classified into three categories – one, the ‘content’ of the message; second, the ‘context’ of the message and third, the attributes of the message. The content generally consists two things – one, the attributes of the cyclone (such as the probable areas to be affected by the cyclone, the probable location where the cyclone may cross the land, the severity (in terms of wind speed and tidal surge) of the cyclone, the time the cyclone is likely to cross the coast and maybe the uncertainty that the landfall location, severity, timing of the cyclone; second, the action that is proposed (evacuate in this case) to be taken to mitigate the risk due to that cyclone. The context in which the cyclone warning message is communicated to the public is defined by the credibility of the source, the channel used to disseminate the warning, the frequency with which the warning is disseminated and the language in which the warning is disseminated. The situational or” receiver” characteristics: These situational and "receiver" characteristics can be classified into six general categories viz. environmental cues, prewarning perceptions, exposure conditions, social influence, socio-demographic characteristics and psychological factors. Environmental cues refer to physical characteristics of an emergency setting such as visibility of the hazard. Pre-warning perceptions refer to the perception about the risk and proposed measure to mitigate that risk, based on the past-experience of the individual. Without adequate emergency information, people may disregard warnings if their risk perceptions are already biased. Exposure conditions refer to the livelihood and other assets that are exposed to the cyclone hazard. Social setting factors characterize the context in which the emergency information is received. Socio-demographic characteristics of the receiver, such as resources, gender, and socioeconomic class, can influence hearing, understanding, believing, personalizing, and responding to the warning. Psychological characteristics of the receiver, for example, cognitive abilities, personality, or attitudes can also influence reception of a warning. While the conceptual framework in figure 1 based on disasters’ literature discussed above provides a useful starting point to understand the phenomenon of ‘response of the public to hazard warning’, most of the studies cited in the literature have been conducted in the US context. Some of these factors may or may not be valid in the Indian context. Or some new factor, which has not emerged in the studies cited in literature, might turn out to be relevant in the Indian context. Hence an exploratory study was conducted to identify the relevant factors in the Indian context. 4. Design of the exploratory study It may not possible to manipulate all the factors (mentioned in section 3) to increase the likelihood of the adaptive response to warning messages, but an awareness of them allows informed senders to anticipate their consequences and include information in warning message to counteract these tendencies, Nigg (1993). The purpose of this study is not a comprehensive study of all the factors. The objective is to identify those factors that are particularly relevant in affecting the cyclone warning-response process in the Indian context. Of particular interest in this study are the beliefs and mental models (representations people have in mind about real or imaginary situations) of people that underlie the perceptual and evaluative processes that occur after the warning has been received and before a person actually responds (either by evacuating or not evacuating). For eliciting the beliefs of the people underlying the warning-response process, a case study was conducted in the context of the cyclone that had crossed the coast of Krishna district in Andhra Pradesh coast on the night of 15th of December 2003. 4.1 Unit of analysis The majority of the research on risk communication and the warning-response process has focused on the individual as the unit of analysis to investigate the warning response process. The unit of analysis for this study too, is an individual. 4.2. Description of the case study area Krishna district (figure 1), named after the river Krishna that flows through the district into Bay of Bengal, is located at 15° 43’ N and 17° 10’ N Latitude 80° 0’ and 81° 33’ of E, on the East coast of India in Andhra Pradesh state. Krishna district has a coastline of about 88 Km and an area of about 8,727 sq. Km. Figure 3: Location of the case study area on the map The district is divided into 50 sub district administrative units called ‘mandals’. Out of these 50 mandals, 4 mandals i.e. Machilipatnam, Koduru, Nagaylanka and Kruthivenu, are coastal mandals and most vulnerable in case of a cyclone. 9 villages in these 4 coastal mandals were visited for interviewing the people of these villages. 3 mandals i.e. , Koduru, Nagaylanka and Kruthivenu are entirely rural mandals with absolutely no urban areas. Machilipatnam mandal has two urban areas with the rest of the mandal being rural. Table 2 summarizes the demographic details of the villages included in the case study.

Methodological Approach The main focus of this study is to elicit the beliefs and mental models of individuals that affect the risk perception and evaluation process. The methodology for elicitation of these beliefs has been inspired by the Mental Models Approach to risk communication. Mental models have been used by psychologists since long for eliciting representations in the mind of real or imaginary situations. They have been used in diverse domains. This approach has been made popular in the risk communication domain by Morgan et. al (2002). According to Mental Models approach, though the audience for communication does not have complete understanding of its subject matter, for most risks, people have at least some relevant beliefs, which they will use in interpreting the communication. If they must make inferences about the risk, they will assemble their fragmentary beliefs into a “mental model,” which they will the use to reach their conclusions. Thus this approach tries to elicit, understand and describe lay beliefs about a risk in terms of mental models, which can then be compared with the formal, or “expert,” model capturing the pooled beliefs of technical specialists about the same phenomenon. The comparison shows both the gaps between the models and the current knowledge which are then used to develop and design effective risk communication that provide information that people need to make informed decisions about the particular risk. Morgan et al (2002) propose the following steps that are typically followed for applying the mental models approach to risk communication: Step 1. Create an expert model – based on the review of the current scientific knowledge about the processes that determine nature and magnitude of risk, by experts from diverse disciplines. This knowledge is formally represented in the form of an influence diagram (drawn from decision theory) Step 2. Mental model interviews – involves conducting open-ended interviews, eliciting people’s beliefs (both correct and incorrect) about the hazard, expressed in their own terms. Responses are analyzed in terms of how well these mental models correspond to the expert model captured in the influence diagram. Step 3. Conduct structured initial interviews – involves creating a confirmatory questionnaire whose items capture the beliefs expressed in the open-ended interviews and expert model. Administer it to larger groups, sampled appropriately from intended audience, in order to estimate the population prevalence of these beliefs. Step 4. Draft risk communication –involves using the results from the interviews and questionnaires, along with an analysis of decisions that people face, to determine which incorrect beliefs most need correcting and which knowledge gaps most need filing. Then draft a communication and subject it to expert review to ensure its accuracy. Step 5. Evaluate communication – involves testing and refining the communication with individuals selected from the target population, using one to one read aloud interviews, focus groups, closed form questionnaires, or problem solving tasks. The Mental Models approach discussed above has not been applied in its entirety in this study. The approach has been modified to suit the context of this study. Step 4 and step 5 mentioned above are beyond of the scope of this study; hence they have been skipped completely. The conceptual framework of the warning response process and factors affecting this process (figure 2) described in section 3 is used in place of the expert model. The hazard contexts for applying the mental models approach to risk communication in the literature and in this study are different. This has implications for ‘about what’ the metal models are elicited. Most hazards to which mental models approach has been applied previously have been slow developing hazards environmental and health hazards like climate change, radon in homes, AIDS risk etc. The time frame for eliciting desired response from the targets of the risk communication is not very strictly bound in time. Whereas the cyclone warning is meant for a rapid onset disaster situation in which the time frame to act is very short (typically 48 to 24 hours only) and strictly bound in time. The difference in the time frame for eliciting response means the focus of risk communication differs in both situations -in situations where health or environmental hazard is slow developing and the main focus of the risk communication is to educate people about the different aspects of risk due to the hazard so that they could take informed decisions. In case of rapid on-set disaster situations like cyclones and floods the main focus of the cyclone warnings is to generate immediate response (generally evacuation) from people to avoid that risk (specifically the risk of mortality). Therefore eliciting mental models ‘about what’ varies in these two situations. In the first situation the mental models ‘about the hazard, its exposure and effects’ are elicited. In the second situation in addition to the mental models about the hazard, exposure to it and its effect, the mental models about the warning (risk communication) itself are also elicited. In the existing studies in literature, mental models underlying people’s response to the risk communication already being communicated were not studied explicitly. Only the mental models about the risk at hand were studied. Of course, the gaps that were observed between the expert models and lay beliefs did point out that the existing risk communication was not adequate and in an indirect way did include mental models underlying people’s response to the existing risk communication. 4.4. Sample size The aim of the mental models interview was to find out which beliefs are “out there” with some reasonable frequency. Maharik and Fischhoff (1993) cited in Morgan et al. (2002) had plotted number of interviews conducted against the cumulative number of concepts encountered in the set of interviews they conducted. They found that each of the first few interviews yielded quite a few new concepts. However, after about 20 interviews the curves began to reach an asymptote as very few new concepts arise. In this study 44 individuals in all were interviewed (about 3 to 6 respondents from each village). Table 3 presents the distribution of the sample by village and gender.

Instrument design and mode of conducting interviews The method for eliciting the mental models varies with domain in which they are being applied. Incase of eliciting mental models of people for clearly defined tasks it maybe possible to create computational models that simulate the behaviour following from the beliefs that investigators have proposed as constituting mental models. In complex domains with unclear bounds and uncertainty involved, it is difficult to create computational models that simulate behaviour. Warning- response process, which is the focus of this study, is complex process without well-defined boundaries. For eliciting mental models and beliefs of people in such a situation, we use the approach followed by Morgan et. al (2002) in which they “…use a form of think aloud protocol that provides as much freedom of expression as possible, within the constraints of directing attention to the focal topics.” The main idea was to elicit the beliefs of the people without biasing them about what we wanted to hear. For guiding the mental models interviews the topics to be explored were put in an openended questionnaire format. The questionnaire included the topics based on the factors that were identified as relevant from the literature and as presented in the conceptual framework in figure 1. Two factors were not explicitly included in the questionnaire – First was message attributes such as clarity, specificity, consistency and accuracy with the exception of uncertainity. This was because for evaluating these factors, study of the actual warning messages passed on to the public would be required. This was not possible as the final warning that reached the public was rarely in written form. Though there are written records available of the warnings that were received by the district collector from the IMD and state relief commissioner final warning that reached the public was almost always passed on verbally to the village secretaries and hence had no written records. One could try to elicit the perceptions of the warning audience about the presence or absence of these attributes. But that was not feasible in this case, due to the time that has elapsed since the event. In a few cases where we informally tried to elicit their perceptions about these intangible message attributes, we could only get responses like “I don’t remember” or some vague impressions. The second factor not explicitly included in the mental models interview questionnaire were the psychological factors such as cognitive abilities, personality and attitudes. The literature in psychology has a number of tools to judge the cognitive abilities, personality and attitude of a person. But administering these tools was not compatible with the mental models interview protocol. These tools could be administered later when getting the confirmatory questionnaires filled. Despite this, one of the psychological constructs, often called the ‘optimism bias’ literature came up in the interviews. The procedure began with general questions on demographic details such as age, gender, educational qualification etc. to give time to the respondent to be comfortable. Then a opening question was asked – ‘Were you present in the village during the December 2003?’ If the answer was yes, then we proceeded further with that respondent. 1. What was your experience during the December 2003 cyclone? Basic prompts that were used to keep the conversation going were: Can you tell me more? Don’t worry about whether its right or wrong, just tell me what comes to your mind. Can you explain why? During this process the interviewer kept on marking the on the sheet the topics that were covered by the respondent during his free flow of conversation. If the topic was only fleetingly mentioned and would require follow up then the interviewer instead of putting a tick-mark, put a circle around that topic in the questionnaire. The interviewer also noted any new points that were raised by the respondent, but were not included in the questionnaire. In case there was no mention of receiving cyclone warning during his conversation after the asking the first question, then the second question that the interviewer asked was, 2. Did you receive any warning about the cyclone? The basic prompts mentioned above were used again to keep the conversation going. When the respondent started only repeating the issues he /she had mentioned, then the interview moved onto the next stage. In this stage the interviewer started asking more focused questions about the topics in the questionnaire that had not been raised or topics that required more follow-up and continued until all topics in the questionnaire were covered. 5. Identification and analysis of relevant factors underlying the warning–response process The study includes those respondents only, who had received the cyclone-warning message. Those villages and groups of people, to whom the warning never reached are not included in this study as the objective is to understand the beliefs and perceptions underlie response once the warning has been received. The warning dissemination process and the causes of warning not reaching certain groups of people constitute a separate paper. 4.1. Identification of the factors underlying the warning-response process Each meaningful statement in the interview was coded. The template for coding was the conceptual framework described in figure 2. Each statement in the interview was assigned to one of the factors in the conceptual framework. Main findings from the mental models interviews about the warning-response process and the factors that affect this process in case of the cyclone hazard in the Indian context are: Warning system / “sender” characteristics Context: Source: Mainly three sources of warning were mentioned – The Mandal Revenue Officer (MRO), the Fisheries department. Both the sources of warning are the official sources. 77% of the respondents said that their source of warning was the Mandal Revenue Officer (MRO) of their respective mandals who sent the message about the warning through the village secretary. Only in Giripuram and Upadda village (18% of respondents), the source of warning was said to be the fisheries department. In Elichetladibba, radio was mentioned as the source of warning (This person could not distinguish between the source and the channel of warning when later in the follow up questions he was asked again about the source of the warning, after he was told that radio was only the channel of warning dissemination. Again in Elichetladibba, another respondent mentioned a private doctor as her source of warning. Channel: The respondents mentioned three channels through which they received the official warning from the government – first, door to door message given by the village secretary and others assisting him, through the public address system in a moving vehicle with the warning given by the revenue officials and the village secretary and third, though interpersonal channels and word of mouth. Door to door messenger was the channel through which 45% of the respondents received warning message. 14% of the respondents received the message through the public address system. 41% heard the warning from interpersonal channels. More women heard the message through interpersonal channels than the men. 18% of the respondents also mentioned hearing the warning from other channels like television and radio. In each village about 1% to 10% households in these villages had television or radio sets. None of the respondents mentioned newspaper as a channel for receiving the warning. When investigated further, it was found that these villages received at most two copies of the newspaper (one at the panchayat office and the other usually at the local shop) which is regional language published in Vijaywada. Language: 100% of the respondent said that they received the warning in their local language. Timing: Only 20% of the respondents had heard the warning 24 hours before the cyclone was expected to strike. About 43% respondents had received the warning about 8 hours or earlier. The rest 37% of the respondents received the warning about 4 to 6 hours before the cyclone occurred. Frequency: 80% respondents had heard the warning at least once. The mean number of warnings heard were 3. Content: Severity: All respondents reported that the warning message conveyed the severity of the cyclone in terms of expected wind-speed. 61% people even reported that tidal surge height that could be expected. When asked how much wind speed was conveyed in the warning, very few remembered a numerical figure between 80 to 120 km per hour. Most of the respondents reported that they didn’t remember the wind speed that was conveyed in the warning. This could be because a lot of time has elapsed since the cyclone occurred. The actual expected wind speed conveyed in the warnings was about 100 Km per hour. When asked, whether the respondents understood the kind of damages they could expect with wind speeds of 100 Km per hour, none of the respondents said they understood exactly. Then they were pressed to give their own estimates of the nature and extent of damage to building structures, life and livelihood assets and infrastructure due to wind speed of 100 Km per hour; and expected inland inundation in Km by a tidal surge of 2m. When these estimates were compared to the estimates of damage given for the similar range of windspeed and tidal surge at the IMD website, it was found that 82% of the respondents had underestimated the nature of damages and the expected inland inundation in Kms. Only 4 % of the respondents were anywhere near the IMD estimates of the damage. The rest 14% of the respondents had over-estimated the damage. Likely time: 100% of the respondents reported that the likely time the cyclone was expected to cross the coast was conveyed in the warning. Location: 98% of the respondents reported that the location where the cyclone was expected to cross the coast was mentioned in the warning. The respondents who has received the warning 8 hours or earlier reported that the warning mentioned that cyclone warning was expected to cross the coast anywhere between Nellore in South Andhra Pradesh and Kakinada in East Godavari district. This spans a distance of about 500 Km of the coastline. Only the warnings that were received a few hours before the cyclone narrowed this range of distance by mentioning that the cyclone was expected to cross the coast anywhere between Machilipatnam (Krishna district) and Kakinada (East Godavari). The distance between Kakinada and Machilipatnam is about 150 Km. One would expect that larger the range of distance, lesser would be the belief of the people that the cyclone may affect them. But another factor important in affecting people’s belief that the cyclone may affect them, is their knowledge and/or perception about the extent of the area of impact of a cyclone that is expected to cross the coast at about 100 Km/Hour. When asked about their estimate of the distance of the coastline that may be affected by the cyclone at 100Km/hour, 77% of the people failed to give any kind of estimate. The estimate of the rest 33% ranged between100Km to a 800 Km. Uncertainty: 100% of the respondents reported that the warning message conveyed that the cyclone would cross the coast as very certain information. No uncertainty about the occurrence or estimates of the severity etc. was conveyed to the people. No attempt by the officials and cyclone warning disseminators, to communicate any kind of uncertainty associated with estimates of the cyclone, was due to the perception on the part of the officials that if they communicated any kind of uncertainty in the estimates about various parameters of cyclone occurrence, then they would not be able to generate the evacuation response from people. According to the officials, even with the cyclone being portrayed as certain in the warnings, it is difficult to convince people to evacuate. In their experience, people had to be forced to evacuate in most cases. Actions to be taken: 100% of the respondents reported that the warning message, warned the fishermen from venturing into the sea. In the warnings that were received many hours before the cyclone, the message also exhorted people to evacuate to safer places or be ready to move to safer places. In the warnings received 3 to 6 hours before the cyclone, the warning message stated that Road Transport buses / Lorries arranged by the revenue department are waiting at such and such place near the village to evacuate the people and take them to such and such relief center. The people were ordered to evacuate their homes. Situational and “receiver” characteristics Though the socio-demographic characteristics like age, gender, educational qualification etc. were asked directly, it was felt that asking questions directly about the other “receiver” characteristics and situational factors would bias the response of the people by putting ideas in their head about what we expect to hear. The idea was that the factors that underlie their perceptual and evaluative stages in the warning response process should come from the respondents, instead of the interviewer suggesting it to them. So instead of asking them directly about these factors, the respondents were asked to describe what did they do once they heard the warning, what was their response (evacuated voluntarily, evacuated by force, not evacuated at all) and why they chose this particular response. We inferred the factors that underlie their perception and evaluation of the cyclone risk, from the reasons they gave for choosing a particular response by mapping these reasons to the factors in figure 1. In the more focused questioning stage they were explicitly asked about the “confirmation” and the “belief in the warning” stage of the warning response behaviour. Confirmation of the warning: 100% of the people reported that on receiving information about the cyclone they tried to confirm it in some way or the other. Two sources of confirmation dominated – friends and neighbours and second the village panchayat officials and the village secretary. A few reported that they switched on the television for more news about the cyclone. There were a few who had heard the warning on the radio or television before receiving the official warning reported that the official warning acted as a confirmation from them. Belief in the warning: 93% of the respondents reported that they believed the warning received from the government. When probed deeper, it was found that the belief was only limited to the occurrence of the cyclone i.e. most people believed that the cyclone would occur, but the severity with which it may occur may not be the same as conveyed in the warning. Most respondents believed that the cyclone might be of lower intensity/severity than the severity conveyed by the warning message. When asked why they believed that the cyclone might be of lower intensity/severity, two factors emerged – one , the false alarms experienced previously and second social cues from the attitude of the village elders, village leaders and other people known to experienced in the matter of cyclones. Response to warning: Only 34 % of the respondents said that they evacuated voluntarily. 20% of the respondents said that they were forced to evacuate and 46% of the respondents did not evacuate at all. When asked about why the respondents chose a particular response, following factors emerged: Pre-warning perceptions Past experience with cyclones: Before December 2003 cyclone Krishna district had experienced two very severe cyclones (more severe than the December 2003 cyclone). One of them was the landmark 1977 cyclone in which, Guntur and Krishna were most severely affected the death toll on the coastal districts of Andhra was more than 10000. Majority of these deaths had occurred due to the tidal surge. The other was the 1990 cyclone in which the chief characteristic was the very high wind-speed experienced. Tidal surge as high and damaging as in 1977 cyclone. The youngest respondent that had been interviewed was 22 years old. All respondents mentioned that they had experienced at least one severe cyclone previous to the December 2003 cyclones and a couple of other less severe cyclones. Majority of the respondents reported experiencing the 1977 cyclone as well. Loss of lives experienced in previous cyclones seemed like an important factor in explaining the perceived risk of cyclone to life. For example, Malkaylanka village in Machilipatnam mandal was one of the villages where extensive loss of life had occurred during the 1977 cyclone as most of the people had been washed away in the tidal surge. These respondents seemed to attach a greater perceived risk to life due to a cyclone. Whereas the people in Girirpuram village, where there had not been many losses of life in 1977 cyclone, the respondents mentioned that since they had survived other cyclones, they had believed that they would survive December 2003 cyclone as well. This aspect would need to be researched further, which would be done in the subsequent stage where a structured questionnaire would be administered to a larger sample. Accuracy of the warning about severity of cyclone: the respondents reported that in the past the government gave the warning about the cyclone and its severity and though the cyclone occurred each time they received the warning, the severity of the cyclone was low most of the times. This may have been because the actual severity of the cyclone may have been lower than what was predicted by the scientists or the cyclone may have crossed another nearby part of the coast as a result of which the villages of the respondents may have felt only peripheral effects of the cyclone. When the respondent’s were asked, whether in their experience majority of the government’s warnings were accurate about the severity of the cyclones or only a few of the warnings were accurate about the severity of the cyclones, 73% responded that in their experience majority of the warnings were not accurate about the severity of the warning. Perception about the quality of stay at relief centers: Respondents also stated that the poor quality of stay at the relief centers was another reason why did not want to evacuate to go to the relief centers. The factors that made the stay at relief center poor quality were water shortage, poor quality and insufficient quantity of food, poor sanitation facilities, no provision of milk for infants, no segregation for men and women at the relief center, and the fact that once the cyclone was over, people had to go back home on their own from the relief centers. No buses and lorries were provided at the time of going back. This perception about the quality of their experience was formed either by their past experience of staying in a relief camp or through the anecdotes they heard from others in the community who had a past experience at a relief camp. Environmental cues Sensory cues from visibility of the hazard: Most respondents mentioned that though they believed the warning about the occurrence of a cyclone, they were not sure whether the cyclone would be as severe as conveyed in the warning in the warning. They followed the wait and watch approach and tried to infer the severity from the sensory cues they received from the environment just a few hours before the cyclone. These sensory cues were drop in the temperature of the atmosphere, height of the sea waves, colour of the sky and the sea, change in the speed of the sea breeze etc. A peculiar pattern was observed from the responses of the interviewees. It emerged in the interviews with fisher-folk that their forefathers could predict the occurrence and severity of the cyclones from the environmental cues many hours before the cyclone occurred. When asked if the present generation too could predict the occurrence of a cyclone and its severity from the environmental cues, majority of them responded that they couldn’t. When asked why, they said that the government had sophisticated technology and devices to predict the cyclones, so they preferred to depend on the government warnings. Yet, they believe the government warning, only for prediction of a possible occurrence of cyclone and for its severity. For inferring the severity of the cyclone they still depend on sensory cues from the natural environment. But, because the indigenous knowledge on how to read the cues from natural environment is being lost gradually, the present generation waits till the last minute when the cyclone has almost reached them and the natural environment provides direct sensory cues for inferring the severity of the cyclone. But this leaves very less time for evacuation and often it is too late for evacuating. Social Influence Level at which the evacuation decision is taken: Many respondents mentioned that decision for evacuation was taken at the community level. After hearing the cyclone warning and the message form the revenue department and other government employees involved in cyclone evacuation, that the RTC buses and lorries were waiting to take them to the relief centers, the members of the community gather together at a common place and the village elders and leaders take a decision on whether to evacuate completely or evacuate partially or not evacuate at all. If there is going to be a partial evacuation, then these leaders and village elders also decide who would evacuate. Usually women, children, old and sick people are evacuated first. The able bodied, strong and younger people often stayed back to ensure the safety of their livelihood assets. The decision at a community level was more strongly observed in the cases where the size of the hamlet was quite small such as Uppada and Interu or where the occupation of all villagers was the same such as fishing villages, such as Giripuram. In case of villages where the warning reached just a few hours before the cyclone and there was no time left for the community to gather together and take a decision on evacuation. In such cases decisions on whether to evacuate or not were taken at a family level but usually after conferring with friends and neighbors. Exposure conditions Security of livelihood assets: 100% of the respondents stated this to be a major concern in their decision to evacuate. This is because main occupation in these villages was either fishing or cultivation. The livelihood assets i.e. boats, nets and livestock cannot be evacuated with them and there are high chances of damage to these assets in their absence during a cyclone. Perception about security of assets and belongings from theft and vandalism: Majority of male respondents said that they believed they didn’t face any threat of theft or vandalism of their belongings in their absence. Lesser number of women had such a belief. More women than men feared that there might be theft in their absence during evacuation. Perception about security of life during evacuation: Because the evacuations were usually made only a few hours before the cyclone or almost at the last moment, the weather conditions have already worsened at the time of evacuation. Respondents, especial at the island villages of Elichetladibba and Esupuram said that they were afraid to cross the river in worsened weather conditions. Some respondents for example at Sorlagondi village reported a few mishaps during the evacuation process in their past evacuation experience and hence felt that evacuation process itself may not be safe. Another such example was a respondent reporting that he was going to evacuate but he and some others returned to the village when an electric pole fell down on the way to the RTC buses and lorries that were waiting outside the village to take people to relief centers. The falling of the pole made the evacuation process seem unsafe to him. Availability of alternatives to evacuation option: Availability of and access to alternative options to evacuation, like existence of pucca houses, school buildings and cyclone shelters also played a major role in the decision of the respondents to evacuate. All respondents showed a preference for the option of taking shelter in a pucca building in or near their village for duration of the cyclone, rather than evacuation. This was because they could be at hand then to salvage their livelihood assets immediately after the cyclone. Psychological factors Optimism bias: A large proportion of respondents believed that they could ensure safety of their livelihood assets, even if the cyclone is very severe. 5.2. Analysis of association between factors and evacuation behaviour In section 5.1 the factors that explain the warning response process in case of the cyclone hazard in the Indian context were identified using the exploratory mental models interview process. In this section a quantitative analysis is done to further explore whether these factors are associated to the response. The sample size of the respondents is small (because of the mental models interview process is time consuming). Therefore, only a preliminary analysis of the association of the above-mentioned factors with response is presented here. A more robust analysis would be done once a structured confirmatory questionnaire made on the basis of the findings of the mental models interviews, is administered to a larger sample, to explore in depth each of the factors underlying the warning response process. Some of the factors could be coded as dichotomous nominal variable. The evacuation behavior can also be coded as dichotomous nominal variable viz. the respondent evacuated or the respondent did not evacuate. For the purpose of this analysis those who were evacuated by force have been classified into the ‘not evacuated’ category. For the nominal variable representing a factor, one of the two response choices could be selected for each respondent, on the basis of the interviews of the respondents. Table 4 presents how some of the factors were coded as dichotomous nominal variables. Table 4: Factors that were converted to dichotomous nominal variable S. no. Factor that affects the perceptual and evaluative processes underlying the response of the individual to the warning 1. Type of Channel: Channel through which warning information was received – (a) official, (b) interpersonal 2. Number of Channels: Received warning through – (a) single channel (b) multiple channels 3. Timing: Warning was received – (a) one day in advance (b) on the day of the cyclone 4. Frequency of warning: (a) Once (b) more than once 5. Accuracy of the warning about severity of cyclone: In the experience of the respondent, how many warnings received from the government are accurate about the severity of the cyclones (a) Majority (b) A few 6. Environmental cues: For estimating severity the respondent relies more on the sensory cues received from the environment- (a) yes (b) no 7. Safety during evacuation: Respondent’s perception of safety of life during evacuation – (a) OK (b) not good 8. Respondent’s perception of quality of stay at the relief center (a) OK (b) Not good The objective was to test whether evacuation behaviour is independent of a particular factor or whether there is a statistically significant association between evacuation behaviour and a particular factor. The hypothesis was specified as: Ho: Evacuation behaviour and the factor i are independent of each other H1: Evacuation behaviour and factor i are not independent. To test this hypothesis Fisher’s exact test, which is statistical test used to determine if there are non-random associations between two categorical variables. It consists of calculating the actual (hypergeometric) probability of the observed 2x2 contingency table with respect to all other possible 2x2 contingency tables with the same column and row totals. The probabilities of all such tables that are each no more likely than the observed table are calculated. The sum of these probabilities is the p-value. If the sum is less than or equal to the specified significance level, then the null hypothesis is rejected. This test does not indicate the direction of causality or the strength of association between the two factors. Table 4 presents the results of Fisher’s exact test. Table 5: Results of the Fisher’s exact test S. no. Association between the Criteria 1 Criteria 2 1. Evacuation behaviour Type of Channel 2. Evacuation behaviour Number of Channels 3.

The type of channel through which the warning was received, the time of receiving the warning and the frequency of receiving warnings do not seem to be significantly associated with evacuation behaviour. For exploring the significance of the type of channel on the response of individual to the warning, experience of the people with more number of channels would have to be investigated, than just the two channels that people mentioned in the interviews. Timing of receiving the warning may not have a very significant association on decision to evacuate, because in the Indian context most people tend to wait till the last minute to evacuate relying on their sensory cues from environment to infer the severity of the cyclone. The frequency of receiving warnings may not be significantly associated with the evacuation behaviour due to the same reason as mentioned above. In the next stage of the study, when a survey instrument would be administered to a larger sample, better ways (than the dichotomous nominal variable) of measuring the factors would be devised, so that more powerful analysis of association of the various factors with evacuation behaviour could be done and also multivariate methods to establish direction of causality can strength of association could be applied. 5. Observations and directions for future work There are a number of factors that affect the warning-response process of individuals to cyclone hazard. Four factors that seem to be very important in understanding response of individuals to the cyclone warnings are – accuracy of the government warning about severity of cyclone experienced previously, the perception of the people about the severity of the cyclone, perception of the people regarding the quality of stay at the relief centers after evacuation and the concern for the security of their livelihood assets. In the next stage of the study some of the propositions (which have been identified as key propositions in the Indian context) would be tested and/or developed further. In this stage the study would have both confirmatory and exploratory components. Some propositions might be tested empirically using confirmatory methods and survey instruments and some propositions might be developed further using exploratory methods. It would be useful to conduct similar studies in case of other rapid on-set natural and technological hazards, so that common principles underlying the warning-response process in the Indian context can be elicited.
