Policy Gaps in addressing Household energy, Indoor air pollution and Health issues in India Dr Uma Rajarathnam, Enzen Global Solutions Pvt Limited, 90, Hosur Road, Bangalore. Introduction Indoor air pollution due to solid fuel usage is one of the major environmental risk factors for ill health in developing countries. In India a large population still continues to be dependent on biomass energy, according to the Census of India 2001 about 70% of all households and 90% rural households still continue to use fuel wood, cow dung cake and crop residue for cooking while 56.4% do not have access to electricity (RGCC, 2001) Combustion of solid fuels in traditional, low efficiency devices emits considerable quantities of pollutants such as particulates, carbon monoxide (CO), polycyclic organic matter and formaldehyde. In poorly ventilated households, concentrations of some of these pollutants are ten to hundred times of health related standards/guidelines. The resulting health implications are reported to be high among women and children. As per the reported burden of diseases estimate, indoor air pollution is the third most important risk factor (next to poor water and sanitation and malnutrition) of ill health and responsible for 17% of all deaths among children under five in India (Smith KR, Mehta S, Feuz M. 2004). Switching from solid unprocessed biomass fuels to more efficient clean fuels such as LPG and biogas can reduce indoor air pollution levels substantially and improve health for many poor people. However the switch towards cleaner fuel is taking in slow pace. In addition to the clean fuel options, interventions such as improved cook stoves with high efficiency, improved ventilation, behavioural change etc. can help in reducing the exposure to indoor air pollution levels. Implementation /promotion of these interventions need to be supported through suitable policies at national and local level. This paper review the existing national policies to address the indoor air pollution issues in India and to identify the gaps in existing policies and to make suitable recommendations/ strategies to address them. Current status, trend and projected demand for household energy use in India Traditional fuels, which are also known as non-commercial sources of energy are important sources of energy especially in rural areas. It is estimated that about 90 % of the rural household energy demand is met through non commercial fuels such as fuel wood, dung cake and crop residues (Pandey 2002). These fuels dominate the domestic sector and are primarily used for cooking.. In terms of quantity, biofuel consumption for cooking at national level during 2001 was about 379 million tonnes/year. Among various biofuels used for cooking in rural households, share of fuelwood was relatively high; share of various biofuel was about 74:16:10%, respectively, of fuelwood, dung cake and crop waste, at a national level (Habib et al 2004). With urbanization and economic development, people tend to move up in energy ladder. However the shift is more in urban areas. As shown in the Table 1.1, LPG usage in urban areas has increased from 26.9% in 1991 to 48% in 2001. However in rural areas the decline in use of solid biomass fuels (Firewood, crop residues and dung cake) is marginal. Yet with the population growth, the actual number of households using solid fuels have gone up from 101.8 million in 1991 to 124.4 in 2001 (RGCC, 2001). Table 1.

Projected energy demand shows considerable increase in LPG demand for household cooking. However there is no decrease in fuelwood demand. Table 2.

Figure 1 shows the thermal efficiency and CO and particulate emissions of solid fuels and clean fuels. When people move up in the energy ladder (from dung- crop-woodkerosene-Gaseous fuel), efficiency increases with emission reduction. Figure 1.

Recent studies have reported that a large fraction of particulates emitted from solid biofuels are of black carbon that could add to global warming (Venkataraman, Habib et al. 2005). In poorly ventilated households, concentrations of some of the pollutants are ten to hundred times of health related standards/guidelines. Most of the studies on indoor air pollution done in the past were focusing on two major pollutants namely particulates and carbon monoxide (CO). Summary of reported concentration and exposure levels of particulates from selected studies carried out in India is shown in Table 3. Table 3 Concentration of particulates as reported in recent studies in India Place Fuel Concentration of particulates (ug/m3) 4500 400-520 2860 1370 3470 2630 1190 520 500 500 Garhwal (Hilly area) Urban slums Urban poor household Delhi Ahmedabad Rural Tamilnadu Wood Biomass Biomass wood Cattle dung wood Coal Kerosene Gas Wood Andrapradesh Agricultural waste 2000 Biomass 325-850 RSP RSP Haryana Biomass RSP 4500 TSP/RSP Reference TSP RSP RSP RSP TSP TSP TSP TSP TSP RSP Saksena et al. 1992 Smith 1996 Smith 1996 Saksena et al, 2003 Raiyani et al., 1993 Balakrishnan et al, 2002 Balakrishnan et al, 2004 TERI, 2002 Above table shows that the levels of particulate matter are alarmingly high when compare to 50 g/m3 of 24-h mean air quality guidelines recommended by the World Health Organization (WHO 2005). Exposures to such high levels of indoor air pollution have serious consequences for health, particularly among women and children as they spend more time in indoor environment. Health effects of indoor air pollution Though epidemiological studies linking health impacts of indoor air pollution carried out in India are limited by number, considerable numbers of studies from other developing countries have reported health risk of exposure to indoor air pollution. More than a dozen studies reported the relative risk of exposure to indoor air pollution with Acute Lower Respiratory Infection (ALRI): Pneumonia in young children and chronic obstructive pulmonary disease in adult women. Few published studies reported significant impacts of use of solid fuels on tuberculosis and cataracts. Exposure to pollutant in biomass smoke can be linked to low birth weight and adverse pregnancy outcomes. The major diseases associated with solid fuel usage and summary of the evidences are shown in Table 4. Table 4: Health effects of the use of solid household fuels in developing countries Health Outcome Acute lower respiratory infections (ALRI) Chronic obstructive pulmonary disease (COPD) Blindness (cataracts) Lung cancer (coal only) Population affected Relative risk (95% confidence interval) Strength of evidence 2.3 (1.9, 2.7) <5 years Females >15 years Strong 3.2 (2.3, 4.8) Females >15 1.3 – 1.6* years Females >15 1.9 (1.1, 3.5) years Females >15 1.5 – 3.0 * Tuberculosis years * - Range of results in published studies Source: Smith et al 2004 Strong Intermediate/ moderate Strong Intermediate/ moderate According to the reported burden of diseases estimate, indoor air pollution is the third most important risk factor (next to poor water and sanitation and malnutrition) of ill health and responsible for 17% of all deaths among children under five in India (Smith KR, Mehta S, Feuz M. 2004). Considering the impact it is important to take action to alleviate the adverse health impacts of indoor air pollution. Role of key stakeholders in policy formulation process to address indoor air pollution issues in India Indoor air pollution is a multi-dimensional problem. Many agencies including ministries in the state and central government, planning commission, Research Institutes, Non Governmental Organisations (NGOs), multinational organizations and other donor agencies are involved in managing household energy, indoor air pollution and health issues in India. The planning commission established by the government of India in 1950 is responsible for assessment of all resources of the country and preparation of development plans for the most effective and balanced utilisation of resources and determining priorities. However agreement to the plan is the responsibility of the Prime minister and Chief Minister of the States, meeting in the committee. Ministry of Finance allocates funds to various ministries to support /implement various development plans. The Energy Policy Unit in the Planning Commission studies and analyses the inter-sectoral issues on energy. They coordinate with various ministries, local authorities and NGO’s to integrate their views in preparing development plans and allocation of funds to various ministries. Indoor air pollution issues have linkages with various sectors namely health, environment, rural development, renewable energy sources, housing, poverty alleviation, oil and natural gas, women and child development; hence addressing indoor air pollution issues cut across several ministries. Table summarises role of various ministries involved in addressing indoor air pollution issues in India. Table 5 Role of various ministries involved in addressing indoor air pollution issues in India Ministry Ministry of Health and Family Welfare (MoHFW) Ministry of Environment and Forests (MoEF) Ministry of New and Renewable Energy (MNRE) Ministry of Petroleum and Natural Gas (MoPNG) Role Nodal agency dealing with health related issues. Sponsored few research on health risk assessment of indoor air pollution Responsible for implementation of policies and programmes relating to conservation of Forests, wildlife; afforestation and regeneration of degraded area; prevention and control of pollution and protection of the environment. Support research, design, development, demonstration, commercialization and deployment of new and renewable energy systems. Ministry has implemented three major programme namely Biogas development, National Programme on Improved Chulhas (NPIC) and Integrated Rural Energy Programme (IREP) for meeting the rural energy needs, particularly cooking energy. Responsible for production, supply, distribution, marketing and pricing of petroleum products Ministry of Rural Development (MoRD) Ministry of Women and Child Development (MoWCD) The ministry is promoting panchayat raj institutions as an effective forum for decentralized planning, formulation and implementation of rural development programmes. The MoWCD supports several programmes such as training for employment and income generation, awareness generation and gender sensitization which are directed toward empowerment of women. While all ministries have some policies/initiatives to address indoor air pollution issues directly or indirectly, integrated approach/coordination between various ministries is still missing. Analysis of existing Government policies to address indoor air pollution issues in India A wide range of interventions can help in reducing indoor air pollution. These interventions can be grouped under four major categories namely (i) Shifting to clean fuels particularly LPG (ii) Technical interventions such as improved stoves, Biogas, Biomass gasification (iii) Improved ventilation though use of hood and building design (iv) Behavioral change. Suitable policy measures are required to promote these interventions. Shifting to clean fuels: Switching from solid unprocessed biomass fuels to more efficient clean fuels such as LPG, biogas, kerosene and electricity can reduce indoor air pollution levels substantially and improve health for many poor people. Compare to other clean fuels, electricity for cooking is expensive and also access to electricity is uneven. About 57% of rural households and 12% of the urban households (total of around 84 million households) in India remain unelectrified in 2000 (UNDP 2004). Even in the electrified villages, erratic power supply is a problem. Hence use of electricity is not widely accepted option for cooking. Cooking with LPG is convenient and also produces less emission. It has been reported that if a household shift from crop residues to LPG, indoor air pollution levels could be reduced by 95% (Smith, Zhang, Uma et al 2000). Recent cost effective analysis done by WHO reveals that by providing LPG, biogas or modern biofuels to 100 million homes would reduce the exposure levels of harmful indoor air pollution levels among 473 million people and save 282 000 pre mature deaths due to respiratory diseases per year (WHO 2006). The Government of India has taken several measures to encourage the use of LPG and kerosene to meet household energy needs. Liberalisation of LPG market improved the availability of LPG and kerosene. Till early 90’s, the supply of LPG was limited, as a result very few households used LPG for cooking. Waiting list to get a new LPG connection was long; some times it took one or two years to get a LPG connection. In 1993, the government liberalized the LPG market by allowing the private markets to sell LPG and kerosene at market price. Retailers have been authorised to sell imported LPG, while the custom duty has been reduced in a phased manner. Public sector under takings (PSUs) have taken measures to increase the availability in rural areas. Extension counters were opened in rural areas. As a result, the number of LPG connections increased from 18.1 million in 1992 to 79.6 million by 2004 (Teddy 2004/2005). Subsidy on LPG and kerosene is another important measure to promote the clean fuels for cooking. The subsidy on LPG is universal and not restricted to poor or low-income group. Also the subsidy is not restricted to number of connections per household. The distribution of connection and consumption of LPG between the poor and rich and between rural and urban suggest that urban middle and high income category enjoy the maximum benefit of subsidy. Analysis carried out by TERI indicates that 76% of LPG subsidy goes to urban areas with 25% of population, and that too among top 27% of households (TERI 2005). The LPG and kerosene subsidy imposes high opportunity costs. For example, the central governments total bill for subsidies to kerosene and LPG together for the year 2002-03 was about Rs 63 billion, which was higher than the budget allocation by the government for primary education and allocation for rural employment programmes. Despite the fuel subsidy, poor often have difficulties to access LPG because of the high initial cost. In order to help overcome this barrier, the state government of Andra Pradesh (AP) launched the Deepam Scheme in July 1999. In this scheme, the government pays the LPG connection fee for women who belong to self-help groups and whose households are classified as Below Poverty Line (BPL) indicated by the possession of white ration cards. The Deepam scheme differs from traditional fuel subsidy in two respects (i) It is targeted for poor and (ii) it is one time capital subsidy in that it subsidizes LPG connection fee rather than the operating cost – the purchase of fuel itself by providing a price subsidy. Evaluation of the Deepam scheme revealed that though it helped in greater penetration, it couldn’t eliminate the biomass or kerosene usage completely. It suggests that the usage of LPG is strongly income elastic at low income levels. As far as free or biomass is available, households will continue to use traditional fuels. In addition, implementation bottlenecks such as limited choice, inability of suppliers to supply equipments on time, co-ordination problems at local level contributed to dissatisfaction among the recipients. (World Bank 2003). Kerosene subsidy Till early ‘90s, kerosene was supplied through public distribution system (PDS) only and the cost was subsidized. In 1993, the government allowed private firms to import and sell kerosene however the price is higher than those being sold through PDS. In 1999 –2000, 61 percent of rural households purchased kerosene from PDS only and 20 percent holds depend on kerosene sold through private markets, whereas 19% of households bought kerosene from PDS and market. Where as in urban areas, 46% of households relied only on PDS and 32% of households bought kerosene only from markets and 22% households used both PDS and market for kerosene (Gangopadhayay et al 2004). Kerosene in rural areas is primarily used as a fuel for lighting, whereas in urban areas its primary use is for cooking. Numbers of reports suggest that kerosene subsidy is misused by way of illegal diversions. The diverted supply could be for household use (at higher prices than the subsidy price) or for adulteration in transport sector mainly for diesel. It has been reported that the diversion in kerosene supply could be as high as 50% (UNDP/ESMAP 2003). Considering the misuse of subsidy and heavy burden on the Government’s expenditure, it is time to reconsider the existing subsidy scheme. It has been suggested to revise the existing subsidy scheme by targeting the subsidy for lower economic strata. For this, coupon or smart card based subsidy with efficient administrative scheme could be explored. (TERI 2005, Planning commission 2006). As a long term policy recommendation, complete electrification of rural households and elimination of kerosene subsidy will provide a way to switchover to LPG. Improved technologies Historically, the renewable energy program in the country can be traced back to late 1940’s involving biogas plants and improved cook stoves programs, but system-wise it was the oil- shock of 1973 that institutionalized the drive for renewable energy. To provide focused attention to the development of renewable a separate DNES (Department of Non-conventional Energy Sources) was set up in 1982, which a decade later culminated into a full-fledged MNES (Ministry of Non-conventional Energy Sources) in 1992. Recently it has been renamed as the Ministry of New and Renewable Energy (MNRE). In a little over two decades since its institutional inception, India’s renewable energy program has become one of the largest in the world. The MNRE today offers the legal, financial and administrative framework for promotion and investment for a range of environmentally benign renewable energy technologies (RETs) be it biomass, solar, wind or water. The potential of various technologies implemented and the achievement is given in Table 6. Table 6 Potential and achievement of renewable energy devices Source/Technology Potential Cumulative India’s position in achievement the world As on 31.03.2005 Biogas plants 12 million 3.7 million II Improved Chulhas 120 million 35.2 million II Biomass gasifiers -----66.23 MW I Solar PV 20 MW/sq 264 MW V km Solar water heating 1,40 million 1 million --sq. m collector area collector area Wind pumps (water -----1015 --pumping) Solar PV pumps ------6818 -----(water pumping) Source: Website:http://mnes.nic.in The important government programmes addressing the energy conservation and indoor air pollution are the National programme for improved Chulhas (NPIC), National Project on Biogas Development (NPBD) and the solar energy programme. The National programme for improved Chulhas (NPIC) was introduced in 1986-87 and as per the coverage; it is second largest in the world after that of China. Under this program about 35 million improved cookstoves were disseminated through state nodal agencies and NGOs. However, with just about 25% of the potential population covered by the NPIC in about two decades of operation and with mud IC’s having a life span of 5-8 years considerable challenges remain in scaling up of these technologies. The current IC dissemination rate of 1.7 million /year, as per project achievements, would require another 48 years to cover the remaining potential population. Another setback is since 2002, central government discontinued its support but directed state government to continue the program. As a result many technical backup units were closed. Only few states are taking up actively. Considering the two decades of implementation it is worth reviewing the experience of government supported NPIC programme. Following table compares the international experience with the Indian NPIC programme. Table 7 Characteristics of the NPIC (National Programme on Improved Chulhas) compared to international experience International practices in stove dissemination There is focus on need-based users NPIC practices There is a target-based approach; stress on number of villages to be covered rather than number of households. Demand for chulhas is not taken into consideration There is minimal subsidy for the stove Subsidy on chulha accounts for the largest share from government or donors (50%) of government support. Users may be willing to pay more for better chulhas There is maximum support for R&D The programme funds technical back-up units, but (research and development), production funds R&D and NGOs inadequately. Support for and distribution of stoves, credit, capacity capacity building and awareness generation is also building, and public awareness insufficient. There is close interaction between There is adequate interaction between producer and designers, producers, and users of stoves user, but negligible between designer, producer and user There is a dependence on centralised For fixed chulhas, there is no scope of centralised production of stoves and its parts to reach production as these are built at user’s homes. There more people, because cost of production is mass production of chuha parts (chimney, cowl, is less. etc.) undertaken by private manufacturers, but no mass production of firebox is in existence. There is onus on the producers and Consumer needs met by self employed designers to meet the needs of consumers workers/NGOs through changes in chulha design, low inputs from designers There is provision for long term funding There is long term target based funding by the government, routed through nodal agencies and disbursed through NGOs for implementation Source: Fire without Smoke, Learning from the National Programme on Improved Chulhas, TERI publication, 2004 The Government of India’s decision in 2002 to transfer the responsibility of NPIC to states provides both a risk and opportunity for developing new state level programmes based on the lessons learnt. Efforts towards commercialization of cookstoves have to be taken up for large scale dissemination of the stoves to be adopted by rural households. The government could also consider on setting technical standards, providing credit facilities and encourage promotional support to chulha manufacturers. Need to reorient the collaboration between designers, manufactures and consumers. Innovative approaches are required to promote improved chulhas. One such approach is to emphasize health benefits to convince the non users. Effective communication and awareness creation program will help in this regard. Coordination of information on Chulhas and capacity building activities should be strengthened at national level. Based on the past experiences (both problems and achievements) active measures need to be taken to revive this programme. In addition to the Government’s role, NGOs and international organization play an important role in promoting improved cookstoves (Box ). Commercialization approach: Way to promote improved cookstoves on sustainable manner Shell foundation in partnership with USEPA’s initiative on Clean Indoor Air awarded pilot grants to two non governmental agencies namely Development Alternatives and Appropriate Rural Technology Institute (ARTI) to promote reliable, affordable and efficient improved cookstoves and compact biogas systems that reduce people’s exposure to indoor air pollution by adopting ‘part-commercialized’, market-driven approach. This involve multi-disciplinary stakeholders in implementing a social marketing campaign, access to micro-credit through self help groups, promotion of micro-enterprises for decentralized production of improved technologies and awareness creation for large scale promotion. During the pilot programme, ARTI sold about 80,000 improved stoves in the state of Maharashtra and DA sold 1500 improved stoves during 2005. Both these agencies plan to sell about one million improved cookstoves each in next five to seven years (Source: http://www.shellfoundation.org; http://www.pciaonline.org/about.cfm). Government of India has promoted biogas plant through National Project on Biogas Development (NPBD). In spite of subsidy the biogas programme has gained limited success. Affordability, Lacunae in implementation strategy and technical barriers are some of reasons for the limited success of this programme. Improved Ventilation Improved ventilation arrangements in households through hoods, adding windows and creating gaps between the top of the wall and roof can help in eliminating the smoke, their by reducing the exposure levels to indoor air pollution. In India very few households have this practice. However there is no policy initiative to promote such intervention. Behavioral Change Promotion of behavioral changes is one of the effective interventions to reduce exposure levels. For example use, keeping the children away from stove during cooking, reducing the time spent near fire, placement of stove in a better ventilated place and use of dry fuels for cooking can reduce the pollution/smoke levels. Awareness creation and educating rural people about the benefits of behavioral changes can help in promoting them. Recommendations Addressing indoor air pollution in India would mean making clean fuels and better technologies more popular in rural areas. Recommendations for dealing with this issue are: Need for an integrated policy: Effective strategies to reduce the burden of indoor air pollution require commitments from different sectors. Though different ministries aim to address the issue, their efforts stand isolated. There is a need for integrated approach and policy to manage this issue. Increase in supply of modern fuels such as electricity, LPG, etc. in rural areas: Supply of LPG in rural areas should be augmented through increase in lability of modern energyusing devices such as electrical appliances, gas stoves, etc. in rural markets, which can be done through: Development of means of transportation and communication in rural areas and establishment of better distribution channels for modern fuels in rural areas Provision for targeted government subsidies: Considering the merits of LPG in reducing indoor air pollution levels, their usage needs to be promoted in large scale, particularly in the rural areas. The demand for LPG is found to be low due to low purchasing power of rural people. Thus providing government subsidies, that reduce the market price of the commodity, would imply increase in demand for modern fuels in rural areas. Though the LPG price subsidy exists in India, it benefits more of urban and high income categories. Considering the Government’s huge expenditure on subsidy and its beneficiaries, there is a case for targeting the subsidy for poor. Smart card or coupon based delivery mechanism can be used to effectively target the LPG subsidy. Given the fact that kerosene subsidy is not reaching the targeted end users and diverted towards adulteration, Government should consider elimination of kerosene subsidy with other policies to support lighting needs of poor. Provision of subsidy for solar lantern as a short term policy and on the long term expansion of rural electrification net work will help in meeting this goal. Promotion of improved Chulhas, biogas plants, etc: The use of such devices would ensure that the traditional fuels such as fuelwood, crop residue, etc. are utilized optimally. Innovative approaches are required to promote improved chulhas. Better awareness creation is required to promote these interventions. Refernces 1.
