Objectives and goals of the responsible coastal
planning and management
1. Optimize benefits from coastal and
marine resources, specifically for local
communities
2. Identifikasi Penggunaan yang diperlukan
3. Meminimumkan Konflik
4. Mencegah Degradasi Lingkungan
5. Bagaimana caranya?
Konsep ICM
Penilaian Sumberdaya:
comprehensive inventories of coastal
natural and human resources (e.g.
physical and biological data, resource
uses, cultural heritage, traditional land
uses and activities, etc.);
includes long term in depth biocomplexity
research studies;
Konsep ICM
Pendugaan Dampak
assessing the coastal zone vulnerability to
various activity impacts; interactions
between uses and resources;
a tool to help making decisions and evaluate
options for the mitigation and
environmentally sound management (e.g.
spatial and use conflict analysis, GIS models);
based on the best available knowledge and
acknowledging uncertainties;
Konsep ICM
Policy and regulatory framework:
a basic tool for training and education, and for
local community participation in decision
making process; based on analysis of existing
institutional and legal mechanisms develop
comprehensive policy framework to address
coastal issues;
Konsep ICM
Pendugaan osial-Budaya & Ekonomi
understanding of socio-economic incentives at the
local level in suggesting alternative incomegenerating programs;
the simpler the national rules the better they are
understood and followed on the local levels;
the capacity of the community to regulate its own
activities and uses;
to enforce local rules is an important determinant of
perceived management success;
Konsep ICM
Implementasi:
how to apply science and develop and
implement the BMPs?
Comprehensive BMPs are ‘living documents’
open to revision, expansion;
provide consistent national standards and
practices for implementation;
Konsep ICM
Monitoring dan Evaluasi:
assess cumulative effects of changes and
update management program elements to
reflect changing needs and circumstances;
multidisciplinary data as a ‘feedback loop’
evaluation of our activities and their impacts;
Still the question is how?
And what is the driving force
and approach in coastal
management?
My general premise is that “the environment
sets the limits for responsible and sustainable
development".
Why?
Understanding ecosystem's "function, health
and resilience" is an imperative for successful
application of adaptive coastal management.

Site suitability
and use conflict analysis:
an optimal allocation for user functions
• Finding suitable sites for existing and
potential use/activity in the marine and
coastal environment is one of the most
critical challenges facing coastal planning
and management.
Analytical Approach :
1.
2.
3.
4.
Optimal sites are selected based on environmental suitability
analysis and GIS models. Environmental parameters required
for potential activity sites were selected and generic protocol
was developed. Often a modified version of the activity protocol
has to be created and applied based on available and spatially
explicit data.
GIS use-suitability modeling: application of available
environmental suitability indicators from developed protocols;
includes evaluation of the model with existing activity sites.
GIS use-conflict modeling and analysis: identification of exiting
and potential uses,and use conflicts.
Characterization of management issues and options. Providing
outcome scenarios and recommendations, identifying gaps to
help guide future scientific research, monitoring and decisionmaking processes.
Phase One:
1. The most important step is to identify the
environmental conditions necessary for each
use/activity to succeed.
2. Based on extensive literature review and present
knowledge, the environmental use suitability indicators
(parameters or criteria), for activity to be long-term
sustainable, can be identified and derived.
3. Note: ESRI ArcInfo and ArcView software were used to
write algorithms to model protocols, and perform GIS use
conflict modeling and analysis.

Tahap Ke Dua
1. GIS use-suitability modeling : Identification of
areas in which environmental conditions for each
specific use are found
2. This includes spatial analysis (aerial photos and
satellite images); integration of GIS coverages
(data layers) for e.g.: temp, salinity, bathymetry,
water quality, substrate types, benthic biocenoses,
slope, hydrology, geology-pedology, critical
habitats and protected species/areas, etc.
3. GIS application of available environmental
suitability indicators from developed protocols
and evaluation of use suitability models;

Evaluasi Lahan
In the first part of the land evaluation, the qualitative
part, the soil map , an agro-climatic map and a map with
the govermental unit were combined, which resulted in a
map with a number of Land Evaluation Units (LEU's), each
comprising a unique combination of soil unit, climatic
region and govermental unit.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Subsequently, these LEU's were confronted with the soil and
climatic requirements of three types of crops: grass, cereals
and root crops.
The requirements were defined in terms of e.g. texture,
slope, drainage, rooting depth, salinity and temperature.
The definition of the requirements was based on the
workability of the soil with appropriate machinery and the
minimum soil conditions allowing crop growth.
The criteria were increasingly severe for the three crop
types. From the qualitative selection procedure it follows
that (part of) a LEU is either suitable or unsuitable for
mechanized crop cultivation.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
After this qualitative part of the land evaluation, the
production potentials of the suitable LEU's under
water-limited and potential conditions were
calculated with the crop growth simulation model
WOFOST.
This model simulates growth, development and yield
of a field crop, and the water balance of the soil,
under defined weather and soil conditions.

Input-output combinations
General.
As stated before, in an explorative study current agricultural practices are not
the proper starting point. One could consider the in/output tables of the
`best farmers' in a certain region as the criterion for the possibilities of all
farmers in that region. However, this might imply specific structural
differences between regions e.g. differences in education or farm sizes, that
may have disappeared at the end of the time horizon of a study.
The production ecological concepts and the most efficient application
techniques of the various resources required for a crop to grow were applied
to quantify production activities in all regions .
Differences in management and business structure are therefore not taken
into account. This assumption implies that within the time-frame of the
study, there could be no longer any differences in education level and
industrial structure between regions in the system. It should be judged
whether this is plausible.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Arable cropping and grassland.
All input-output relations for arable crops were defined for the cropping system
level. All crop rotations were defined using expert knowledge. The most heavily
demanding crop in the rotation determined the area suitable for that crop rotation.
Three production orientations were defined for arable cropping and for grass:
1. A Yield Oriented Agriculture (YOA),
2. An Environment Oriented Agriculture (EOA) and
3. A Land use Oriented Agriculture (LOA).
For the YOA and EOA activities were defined both with and without (rain fed)
irrigation.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Arable cropping and grassland.
For the quantification of the input-output relations in YOA, the results of the
quantitative land evaluation derived with crop growth simulation models were used
as a starting point.
The simulated yields were corrected for inevitable harvesting losses and losses due
to soil-borne diseases as a result of too narrow crop rotations. The required inputs to
realize the outputs were estimated by using expert knowledge.
To arrive at an economic optimum some substitution of agro-chemical by labor
and/or capital is permitted.

. Coastal Landuse analysis using multiple goal linear

Arable cropping and grassland.
The production activities in an Environment Oriented Agriculture were defined by
means of literature and expert knowledge. In these activities the use of pesticides
was lowered with ca 70 % on an average (compared to the use in YOA).
Part of the pesticides were substituted by mechanical forms of crop protection, but
the decreased use of pesticides also resulted in some 20 % yield loss.
Finally for grass and wheat crops activities in a Land use Oriented Agriculture were
defined. No pesticides were used in these activities and soil productivity was low.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Livestock activities.
Livestock uses feed derived from arable crops or roughage (e.g. grass
and silage maize).
Basically the feed requirements of livestock could be expressed in
some nutritional components, i.e. Metabolizable Energy (ME),
Digestible Crude Protein (DCP), and (for ruminants) in structural
material because of the need for fibrous material.
So in the LP-model, both the nutritive value of arable products and
roughage as the feed requirements of livestock could be expressed in
ME, DCP and structural material.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Nature.
Besides this quantitative definition of agricultural
activities, the preferred locations for nature conservation
and development were shown in a map.
This technical information, based on a set of criteria, is
also used as an input for the scenarios in a post model
analysis.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Constraints
Besides area and labor constraints a set of water constraints and a set of manure
constraints were included in the EC model. The water constraints quantified the
upper limits on water that can be used for irrigation for each of the regions. These
upper limits were determined by precipitation, soil water pools and run-off. The
manure constraints were also defined for each region. In these constraints it is
required that all manure produced by cattle in a region is used for arable farming or
roughage production in that same region.
Since industrial processing activities were also included in the model, not only
demands for primary products like milk or sugar beets were modelled, but also those
for products like cheese, butter or sugar.
In quantifying the demand for agricultural products, two trade situations were
distinguished, one with free trade and one with autarky, and two diets, one
according to current feeding customs and one with more animal products. The
population growth was estimated at less than 0.1 % per year.

Policy views and objective functions
A number of policy views can be distinguished.
The first policy view is focusing on free market and trade: economic productivity and
minimization of costs are the prevailing characteristics.
The second policy view aims at regional development: to maintain employment and
promote income in the agricultural sector are the dominant aims.
The third policy puts the highest priority on nature development and landscape
conservation: here the conservation of the landscape and development of natural
conditions have the highest priority. Agricultural production should be restricted to
the smallest area possible.
The fourth policy view aims at protection of the environment: the negative side
effects of agriculture should be minimized, which is translated in minimization of
pesticide and artificial fertilizer use.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Policy views and objective functions
The policy views are quantified in eight objectives, two agricultural objectives, two
socio-economic objectives and four environmental objectives .
Nature and landscape objectives turned out to be very difficult to implement.
Objectives related to nature and landscape are site- or location-specific, making it
difficult to define a general rule that models these objectives.
Therefore ex post analyses were performed to provide information on the fulfilment
of these objectives.
For instance by designing a map concerning the nature development or conservation
and by confronting the map with a nature and landscape scenario.

Land use scenarios
In the study area, there are four scenarios have been developed by
putting different priorities and bounds to the various objective
functions.
Scenario A: Free market and free trade.
In the free trade scenario agriculture is treated as any other economic
activity. Production takes place at the lowest possible costs. Starting
point is a free world market for agricultural products with minimal
restrictions on social services and environment.
The policy view dominating in this scenario, was close to the policy
view of the USA in the negotiations for the General Agreement on
Tariffs and Trade (GATT).
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Skenario Landuse
Scenario B: Pengembangan Wilayah.
1. In this scenario regional employment within the area has the
highest priority.
2. Income generation for farmers within the agricultural sector is of
main importance.
3. The policy view dominating in this scenario can be seen as
continuation and extension of today's policy.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Skanerio Landuse
Scenario C: Bentang Lahan & Alam.
1. In this scenario highest priority is given to maintain
existing nature areas as much as possible.
2. A spatial separation between nature habitats and
agricultural areas is created. Next of areas strictly
restricted for nature conservation, areas are chosen for
human activity.
3. This scenario represents the policy view of nature
conservation organizations.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Skenario Landuse
Scenario D: Perlindungan Lingkungan.
1. The most important policy view in this scenario is to prevent alien
substances from entering the environment. Different from the
former scenario the main aim is not to preserve or stimulate
certain plant and animal species, but to protect soil, water and air.
2. There is no spatial separation of nature and agricultural areas, but
rather integration.
3. Agriculture can be practised everywhere, but under strict
regulations for environmental protection. This scenario represents
the policy view of integrated agriculture.
http://library.wur.nl/way/catalogue/documents/Sahel/RAP31/RAP31B.HTM
. Coastal Landuse analysis using multiple goal linear
programming…
Each of these four scenarios results in a different land use,
employment, loss of nitrogen and use of pesticides. However, there
are some results that are common for the four scenarios.
All scenarios show a drastic decline in use of land for agricultural
purposes.
The total area in the four scenarios varies between 26 and 92 million
hectares, whereas currently 130 million hectares are used for
agricultural purposes.
Another result is that 1.5 to 2.9 million man years would suffice for the
total agricultural production in stead of the 6 million man years that
are involved in the primary production at present .
Further the loss of nitrogen and the use of pesticides can be reduced
dramatically .
For instance for pesticides 21 to 154 million kg of active ingredient
would suffice in stead of more than 400 million kg at present.

generated
In a first round the `playing field' was determined by optimizing each
of the objective functions in subsequent runs, without putting
(heavy) restrictions on the other objective functions.
Subsequently, the different scenarios were generated by tightening
the most relevant objective functions of a policy view. For policy view
1 the agro-technical objectives are most relevant.
In policy view 2 the socio-economic objectives have a high relevance,
and in policy view 3 and 4 the environmental objectives have a high
priority.

Analisis Sensitivitas
1. It was analyzed whether changes in goals for the different
objectives result in large changes of the regional allocation of
agricultural production. The allocation turned out to be very
sensitive for small changes in the goals for the costs of agricultural
production. This opens the possibility for influencing the allocation
of agriculture over the regions.
2. The aggregate model results for the entire areas, i.e. the values for
the objective functions, are far less sensitive to changes in
parameters.
3. Finally trade-off between various objectives were investigated: the
gain in one objective relative to the corresponding loss in another
objective.

Sensitivity analysis
In the evaluation phase of the study the following issues were considered:
1.
2.
3.
4.
5.
6.
The conflicts between objectives concerning landscape and nature conservation
with strong spatial aspects on the one hand and the four land use scenarios on
the other hand.
Common differences between the scenarios and the actual situation.
Differences in values for the objective functions between the different
scenarios: scope for policy.
Trade off between the different objectives.
Differences in agricultural production between situations with self-sufficiency
and free trade.
The effects of a change in dietary patterns on agricultural production.

Degradasi global muara dan ekosistem pesisir ( ECE) mempengaruhi
sejumlah manfaat penting , atau jasa-jasa ekosistem .
Suatu hal yang penting untuk menilai jasa-jasa ECE, seperti perlindungan pesisir dan hubungan
habitat perikanan , adalah bahwa fungsi ekologis yang mendasari jasa-jasa ini bervariasi secara
spasial dan temporal .
Konektivitas di antara habitat ECE juga memiliki implikasi penting untuk menilai fungsi ekologis
yang mendasari jasa-jasa kunci ekosistem , perlindungan pantai, pengendalian erosi , dan relasi
habitat perikanan .
Rencana aksi diperlukan untuk melindungi dan / atau meningkatkan nilai jangka panjang jasa-jasa
ECE . Karena konektivitas ECE di seluruh gradien darat-laut juga mempengaruhi penyediaan jasa
ekosistem tertentu , maka pengelolaan seluruh kawasan diperlukan untuk mempertahankan efek
sinergis tersebut .
Elemen kunci lain dari rencana aksi meliputi penelitian kolaboratif ekologi dan ekonomi untuk
menilai jasa ECE , meningkatkan kerangka kelembagaan dan hukum untuk manajemen ,
mengontrol dan mengatur kegiatan ekonomi yang merusak , dan mengembangkan opsi restorasi
ekologi .

Interpretation of econometric results
1. Coral reefs and sandy beaches provide the highest
recreational values.
2. Income effects and proximity to the market of
potential visitors significantly affect values.
3. A high level of anthropogenic pressure and scarce
accessibility have a negative impact.
4. Sites with high marine biodiversity and low level of
human development are valued highly.

Discussion of value transfer results
1.
High values in Mediterranean
Europe, UK, California, Florida
and US East Coast determined by
high accessibility, population
density and income effects and
despite high development and
pressure.
2.
Similarly, high population density
in various areas in India and
China positively influence values
despite the high anthropogenic
pressure.
3.
Scarce accessibility and low
population density along most of
the Australian and South
American coast result in
relatively low values.
Rekomendasi
1. Non-market values of coastal recreation are substantial and
should be taken into account in policy decision for the
development or preservation of coastal habitats &
environment damage assessments.
2. Recreation values are highly dependent upon a number of
contextual variables including level of development of a
certain region, accessibility to the site, population density,
biodiversity richness, and level of integrity of the ecosystem.
3. This implies that from the perspective of recreation values,
habitat conservation may focus on areas which are of high
ecological values (e.g., rich in biodiversity) but low economic
values because located in remote areas with low accessibility.
