Implementation of the Costal Zone Management Policy in State of Gujarat
In historical terms, coastal locations have been the favorite destination of population involvements for defense, commercial and other economic reasons. About 20% of the population of India lives in coastal areas, a larger percentage of this being in coastal cities, such as Mumbai, Chennai and Calcutta. One of the major factors responsible for the degradation of coastal ecosystems is the growth in human population that requires space for settlement and other resources, like soil and water.
The need of Integrated Coastal Management in India is well known, on account of the growing population pressure due to accelerated urbanization, itself fuelled by demographic growth and industrialization. Fragile coastal ecosystems are simultaneously attacked by organic and chemical pollution and the degradation of natural resources is sometimes irreversible.
The need to consider equity, security and environment as key elements for the definition of sustainable development should be defended. Moreover, the complex and conflicting interactions of social equity, human security and environmental sustainability within the social process of shaping and building development for present and future generations are important issues to address. Scientific and technological knowledge can make a significant contribution to alleviate and eventually prevent the unsustainable use of natural resources, such as those of coastal zones. There is urgent need for developing a system whereby one can monitor the precious coastal zone of Gujarat by the tool of an Integrated Coastal Zone Management Plan.
Coastal and Marine Environment
Gujarat state has longest coastline of (1,650 km i.e. 21% of the total coastline of India) among all the maritime states of the country, which makes it strategically serving as natural gateway to India. The Gujarat coast extends from Western Ghats in Valsad to Kori creek on the coast of Kachchh in north. The area of continental shelf of the state is 1,65,000 sq. km. The Gulf of Kachchh and the Gulf of Khambhat are the two Gulfs in Gujarat out of the three Gulfs in the country. Extent of the inter-tidal and high tidal mudflats in the Gulf of Kachchh, the Gulf of Khambhat, the Bhal region and the Rann of Kachchh is exceptionally large. Mudflats, mangroves, marsh vegetation, coral reefs and saltpans cover a major part of the coastal wetland. Geo-morphological and climatic variation is very high on the Gujarat Coast. Rainfall varies from an average high of 2500 mm in the south to only 300 mm in Kachchh. Tidal amplitude is also very high which sometimes exceeds 10m in the Gulf of Khambhat and varies between 3m to 8m in the Gulf of Kachchh.
According to census (2001), about 549 villages with the total population of about one million are situated along the Gujarat coast. The longest coastline dotted with 41 ports caters to demand & supply of cargo from the nearest maritime countries like Africa, Middle East & Europe. Besides this, the entire northern India and some parts of the central India also serve as hinterland to the ports.
The coastal area, upto 20 km from the shoreline, is 30,022.25 sq. km. consisting of parts of 11 districts and 51 talukas with 59 towns and 2802 villages. Living resources are rich fisheries in the 375 km wide continental shelf, coral reefs around 34 islands in the Gulf of Kachchh and mangrove vegetation on swampy lands around the coast. Gujarat produces 71 percent of national production of common salt.
COASTAL RESOURCES OF GUJARAT
Coastline of Gujarat was once dotted with mangroves, along the Gulfs of Kachchh and Khambhat and along the south Gujarat coastline. Mangroves in Gujarat are second only to the Mangroves in the West Bengal on the East Coast in terms of area, occurring in about 936 sq. km (FSI, 2005) area in Gujarat. Mangroves play a very significant role in maintaining the coastal environment, reducing the impact of wave action and erosion in the coastal areas, preventing salinity and seawater ingress into the inland agricultural areas, and also providing protection to the coastline from the impact of cyclones. Apart from these ecological functions, mangroves play a very significant economic role in the lives of the coastal village communities. The villagers are dependent on mangroves mainly for fodder, fuel-wood and fishing activities.
There has been degradation of the mangroves in Gujarat over the years. The reasons for this are many, like the dependency of the local and nomadic pastoralist communities on the mangroves for fodder, fuel, diversion of mangrove areas to industries, salt pans, and construction of ports, jetties, reduction in natural regeneration and dying off of the rich mangroves because of decreased influx of fresh water into the mangrove areas, due to construction of dams, both small and big in upstream areas.
2. Coral & Coral reefs
High species diversity and very high rate of biological productivity make coral reefs very important and unique marine ecosystem. Apart from a significant role as carbon sink, they also provide habitat and food for fishes, crabs, prawns and other marine life. Sponges, Polychaetes, Sea Anemones, Octopus, Star Fish, Puffer Fish, Cat Fish, Coral Fish, Bonellia, Sabela, Sea Urchin, Pearl Oyster, Prawns, Crabs, Lobster and Turtles represent notable fauna that lives in association of the coral reef. Reefs are also recognized as breeding and nursery ground for marine life, including fishes. The ornamental aquarium fish species that decorate the aquaria world over occur on the coral reefs.
Major coral reefs in Gujarat are found only along the Jamnagar Coast of Gulf of Kachchh. It is one of the four major coral reef areas of India. Coral reefs in the Gulf of Kachchh are the northern most in the Indian Ocean, but they are geographically isolated. Many islands in the Gulf support fringing reefs. At present, coral reef area is estimated to be about 460 sq. km.
The avifauna of the project area is represented by 130 species belonging to 94 genera and 47 families. The proportion of marine avifauna is more due to coastal region and saltpans.
4. Intertidal and Sub-tidal Biota
The intertidal area (also called the littoral zone) is where the land and sea meet, between the high and low tide zones. This complex marine ecosystem is found along coastlines worldwide. It is rich in nutrients and oxygen and is home to a variety of organisms.
i. Primary Production
Phytoplanktons are primary producers in marine ecosystem. Water balance in the Gulf of Kutch is negative with evaporation being the dominant control over the sum of rainfall and river runoff. Primary production in gulf of Kutch is moderate with 31 genera and 41 species of phytoplankton (GES (March 1999)), In that most common species were Nitzschia, Navicula, Thallasionema, Thallasiosira and Coscinodiscus, while species like Cocolithoporidesm, Cyclotella etc. were rare. The primary production exhibited temporal and spatial variability with seasons and tidal phases.
ii. Secondary Production
The zooplanktons are secondary producers in marine ecosystem which is dependent on phytoplankton’s. The Gulf of Kachchh is moderately rich in zooplanktons with frequent occurrences of high standing stock of organisms. The inner Gulf sustained a higher rate of zooplankton production. The composition was fairly diverse and consisted mainly of copepods and decapods. The other major groups were Chaetognaths, Siphonophores, Medusae, Amphipods, Polychaetes and fish eggs. Contribution of decapods was more in the inner gulf with decrease in diversity. The rich crustacean
fauna, particularly the high population of Streptocephalus, provided a congenial feeding ground for prawns and fishes.
The density & biomass of Macro & Micro benthic fauna is moderate to good in Gulf of Kutch and western part of Saurastra. The Population of both is dominated by foraminiferans, polychaetes, moluscs gastropods and crustaceans.
The Gulf of Khambhat is an area of large tidal amplitudes with the associated strong tidal currents. These result in suspension and re-suspension of bottom sediments continuously in the homogenous waters of the Gulf and high concentration of TSS in water. Only coarse sand with some silt settles inside the Gulf and depositing them on 350 km wide continental shelf. Hardly any benthic organism can settle in this environment.
iv. Marine Algae.
The long stretches of rocky, coralline and limestone substrata of both intertidal and shallow subtidal waters along Gujarat coast and more particularly Saurashtra coast is dominated by assemblage of diverse seaweed communities Gujarat coast harbors around 210 species of marine algae having an estimated biomass of >1,00,000 tones (fresh weight) year-. The gulf contributes to the maximum number of species and biomass level as well for the West Coast of India.
Several species of seaweeds from the Gulf region are being harvested commercially. These are Gelidiella acerosa and Gracilaria dura as Agarophytes: Sargassum spp, Cystosiera spp and Turbinaria spp as Alginopytes and Hypnea, Halymenia as carrageenophytes. The shoreline of the southern coast has gradual slope with high tidal amplitude and moderate wave action.
These are ideal conditions to undertake commercial cultivation for Kappaphycus alvarezii which is economically important seaweeds.
COASTAL ZONE MANAGEMENT IN GUJARAT - CURRENT STATUS
1. Laws and Policies & status of implementation of coastal zone management plan in Gujarat
Coastal Laws and Policies and geographical limit of the coastal zone
The coastal zone management a dynamic process in which a coordinated strategy is developed and implemented for the allocation of environmental, social culture and institutional resources to achieve the conservation and sustainable multiple use of the coastal zone. Gujarat Coastal zone is having global as well as national importance due to its proximate location from Gulf countries. The coastal area in Gujarat mainly cover coastal land (Mudflats, Sand dunes and others) and the coastal waters, which are regulated by a major National legislation “Environmental Protection Act,1986”. In addition to this, two major laws are also applicable namely The Water (Prevention and Control of Pollution) Act, 1974, Coastal Regulation Zone-1991 and Biodiversity Act -2002. The above laws are discussed below in brief.
i. The Water (Prevention and Control of Pollution) Act, 1974
The water pollution act includes all basic aspects, means and mechanisms to deal with the water pollution control. The jurisdiction of this act has been restricted up to 5 km in the sea. The state as well as central pollution control board is the authority to deal with this act in the country.
ii. Environment Protection Act, 1986
The Environment Protection Act is one of the leading environment legislations which deals with the basic aspects of environment in the country. This act deals with the pollution aspects of air, water, land, hazardous substance, industrial emissions and other wastes (Solid, Biomedical etc). This act is applicable to the entire terrestrial area as well as offshore areas of coastal zone in India. The State as well as Central Pollution Control board are regulatory authorities.
iii. Coastal Regulation Zone Notification, 1991
In accordance with the notification of Ministry of Environment & Forest, Government of India under the Environment Protection Act (1986), declaring coastal stretches as Costal Regulation Zone (CRZ) and regulating activity in CRZ. It also states that all State Governments should identify and classify CRZ areas in their respective territories in accordance with the guidelines given in the said notification.
Definition of Coastal Regulation Zone
The coastal area is defined as that stretch of land mass and water mass along the shoreline which are in close proximity to each other in terms of physiographical and biological effects.
For all developmental and ecological purposes, costal land is considered as that stretch of land from low tide line to 500 m from High tide line
The High tide line, as defined in the notification, is the line on the land upto which the highest water line reaches during the spring tide.
The Distance up to which development along rivers, creeks and back water is regulated shall be governed by the distance up to which the tidal effect of sea is experienced in river creeks or back waters, as the case may be.
The distance from the high tide line shall apply to both side in the case of rovers, creeks and back waters and may be modified on a case by case basis for reasons to e recorded while preparing the coastal zone management plan. However, this distance shall not be less than 50 mt or width of the creek, river or back water whatever is less.
These zones have been categories into four zones namely CRZ I (Ecologically sensitive areas like mangroves, coral reef, NP & MNP & S, Wildlife habitat, coastal wetlands), CRZ II (Areas developed close to shoreline), CRZ III (Rural coastal areas and coastal areas within municipal limits or in the legally designated urban areas which are not suitably built up) and CRZ IV (Includes small islands in the state).
Coastal Regulation Zone notification 2011

Current Capacity Building Programs-achievements and limitations
There have been efforts for the implementation of the Coastal Zone Management Plan in Gujarat. There is Gujarat Coastal Zone Management Authority for the management of these affairs. Under the Integrated Coastal Zone Management Plan various institutions working for this goal would have to increase their capacity for fulfilling the proposed programs.
The present capacity of the institutions shall have to be first studied in detail in terms of their ability to overcome various activities proposed under the ICZM, in the next step the detailed assessment of the activities would be done in the Detailed Project Report and accordingly the required capacity building for various projects shall be done for the execution of the projects.
The Govt. of Gujarat already has many well equipped and well trained departments for theimplementation of the Coastal Zone Management Plan. These various institutions that are to be involved in the implementation of the Coastal Zone Management Plan in the State of Gujarat, along with the Gujarat Ecology Commission as the Nodal Agency.
Various institutions such as the Gujarat Pollution Control Board (GPCB), Gujarat Ecological Educationand Research Foundation (GEER Foundation), the Jamnagar Municipal Corporation (JMC) .
In regards to various capacities building programs to be initiated there have been some efforts involve the private sectors such as the industries and the port authorities in the coastal zone management planning process.
Keeping in mind the long coast of the State it is very difficult for the Govt. to implement the coastal Zone management Plan in isolation and therefore there is a immediate need for involving the people, the Stake holders, the Non Government Organizations and the Community Based Organizations in to the implementation process.
The Coast of Gujarat is very long with two gulfs and has various other characteristics all along whichmakes it very difficult for the implementing agency to formulate a single policy for theimplementation of the Coastal Zone Management plan, there need to be setups at local level and regional level so that the local level implementation needs can be fulfilled.

vi. Mapping and Monitoring of Mangroves in GOK at Community Level.
ii. Mangrove Plantation in the Coastal Areas of Gujarat
The State government has also notified large areas of mudflats as forests for scientific management and increased regulation of anthropogenic activities in the mangrove areas. Thus, in all about 1,32,440 ha. (66,593 ha, 7,770 ha and 58,180 ha in Jamnagar, Rajkot and Kachchh districts respectively) of coastal mudflats in the State have been notified as reserved forests.
iii. In terms of Coastal Information Management System
BISAG is the designated nodal agency for several national and state level projects including Department of Space, Govt. of India, sponsored NNRMS, IMSD project, Wasteland Mapping, Wetland Mapping, CAPE etc.
BISAG’s has been undertaking projects related to Coastal Zones some of which are listed below:
Coastal Land Use Information System of Gujarat
Mangrove Atlas of Gujarat
Atlas for Development of Aquaculture
Salt pan Atlas of Gujarat
Information on Potential Fishing Zones
Status Of Gujarat Land Use Coastal Information System Project (Scale of 1:25,000)
Currently BISAG is preparing the Coastal land use Information System for Gujarat. The Coastal Regulation Zone (CRZ) project mapping is completed as per the requirements of MoEF. The Coastal Land use maps are getting prepared for entire Gujarat on the scale 1:25,000 using IRS data LISS-IV and CARTOSAT-I.
Cadastral mapping project for the entire state has been accomplished by this institute. For all the villages, land parcels have been geo referenced to high resolution satellite imagery.
Proposed Coastal Information System For Micro Level Planning
For planning future activities on the coastal zone of the State, to achieve maximum benefits of vast coastal resources with sustainable development, reliable, continuously updated database giving detailed information about present condition of wetland and coastal land use is required.
iv. Activities carried by Gujarat Ecology Commission
Commission has taken up the comprehensive research studies on costal area, which is mentioned here below
Costal & Marine Environment of Gujarat
Ecological Degradation in Gulf of Kachchh and Khambhat
Status of Coral & Coral Reef in Gulf of Kachchh
State of Environment Report
GEC has carried out more than 6000 ha of Community based Mangrove Plantation with the help of various organization and industrial partnership in the area of Gulf of Khambaht and Kachchh.
Commission is also involved in the various environmental conservation activities on the coastal zone of the state.
In a world of rapid population growth and diminishing natural resources, each country has to plan for economic growth in balance with resource conservation and environmental management if it is to make progress in health, food, housing, energy and other critical national needs ( "Coastal Zone Management Handbook" J. R. Clark, 1996). In the coastal areas, high population densities, linked with urban growth, expanding tourism and industrialisation, pose major threats to natural resources and biological diversity. The uncontrolled development is destabilising ecosystems, changing land use patterns and are making communities vulnerable to sea storms. Sustainable use is the only alternative to resource depletion that accompanies excessive exploitation for short-term profit. This requires an integrated coastal zone management information system to plan and coordinate all the varied interests in coastal resource uses.
Gujarat state has about 1600 km, long coast line in the country. It supports a variety of habitats such as mangroves, coral reefs, sea grass beds, algae/ sea weeds, gulfs, estuaries, beaches etc. There are number of activities going on along the coast viz. salt industries, cement industries, import of oil & natural gas besides the pressure of growing population. This puts a tremendous pressure on the coastal zone and thus requires a proper Coastal Zone Management Plan (CZMP) for developmental planning to sustain the environment. In view of this, Coastal Zone Information System (CZIS) has been developed.
