3.4.1.4 Summary:

Analysis report compared with WHO limit for potable water. pH of the samples were almost neutral & TDS

value varies from 368 mg/L to 410 mg/L. Minimum TDS was found at Varsamedi (pond) & maximum at New

Navlakhi. Almost the results of New Navlakhi village meet with the WHO standard. Water can not be used

for drinking purpose except the water of New Navlakhi village. Water can be used for washing, bathing &

other domestic purposes. In absence of alternate source water can be used for drinking purpose as there is

not any toxic constituent reported in the result. TDS, Chloride, Alkalinity, Calcium are slightly higher side due

to ingress of salinity.

3.4.1.5 Marine Water Sampling:

Samples were collected from three different locations. Mode of sampling was grab & its frequency was once

in a month for the study period. All the samples were collected below 25% & 75% depth from the surface.

The samples were collected during high tide & low tide. Samples were passed through zoo planktons &

phytoplankton net. Then the samples were concentrated by centrifuge. Counting of planktons was carried

out with the help of Sidgwic Rafter cell & microscopy. Samples were also collected for study of Benthos from

particular decided area with suitable sampler. Samples were preserved according to the parameters as per

the preservation method given in APHA 21st edition. Temp., pH & DO were measured on site & samples were





brought to the laboratory after preservation. Samples for microbiological analysis were collected once

during the study period in sterilized bottle. Analysis carried out as per IS 3025 & “Methods for the

Examination of Water & Waste Water”‐21st Edition 2005, APHA. The details of water sampling locations are

given in Table 3.4.1.5 and are shown in Figure 3.4.1.5. Analysis reports are presented in Table 3.4.1.5(a) to

3.4.1.6 Summary:

Analysis report compared with WHO limit for potable water. pH of the samples were almost neutral & TDS

value varies from 42936 mg/L to 45512 mg/L during low tide & 40992mg/L to 47140 mg/L during high tide.

Minimum TDS was found at Varsamedi & maximum at Zammuwadi Creek during low tide & TDS was max &

min at Varsamedi creek during high tide. pH, Hardness, BOD, COD & all the heavy metals are within limit. As

DO level is more than 4 mg/L & BOD value is nearer to 4, we can conclude that the condition of sea is

favourable for aquatic lives.

3.5 SOIL & SEDIMENT QUALITY

3.5.1 SOIL QUALITY:

Soil is a vital natural resource, the proper use of which greatly determines the capability of life supporting

system and the socio economic development of the people by providing food, fiber, fodder & fuel

formatting the basic needs of human & animals. However its capacity of production is limited & the limit of

production are set by its in‐transit characteristics, agro ecological settings & its use & management. Beside

the industrial significant the study area is also important for its agricultural activities.

The surface soil within the study area is mainly sandy in nature. This region is categorized under delta coastal

plain, hot humid agro ecological area. There are no hills in the vicinity. Soil Samples of the selected 5 villages

from the study area were collected. The locations selected for collection of soil samples are shown in Table:

3.5.1 and presented in Figure: 3.5.1. Date of Soil Monitoring and location are shown in Table 3.5.1.1.

The samples were collected by shell & augur up to 20‐cm depth from ground level. The samples from each

location were collected once in a month for a period of three months. The soil sample for each location were

also analysed for its texture. In this region mainly comprises of soil. The sediment samples were also





collected. The physico – chemical characteristic along with organic matter of the soil & sediments of study

region are shown in the following Tables 3.5.1(a) to 3.5.1(f).

3.5.1.2 SUMMARY:

The following description was based on the analysis & visual observation of soil of villages of study area.

• It has been found that the pH range of the soil was 7.04 to 7.94. It indicates that soil is almost neutral

and somewhere slightly alkaline. Surface Soil is mainly Sandy clay loam.

• It has been noted that organic matter varies from 0.4 % to 1.4 %. The range of nitrogen is 1.3 to 2.3

mg/100 gm and the phosphorous (PO4) varies from 0.9 to 3.5 mg/100 gm. The presence of nitrogen as

nitrate & phosphorous (PO4) as phosphate are not in sufficient proportion. Therefore it is not suitable

for agriculture purpose.

• The calcium and magnesium are macro nutrient of plants. As per analysis their concentration varies

from 1.9 to 3.2 meq/100 gm and magnesium varies from 0.9 to 2.7 meq/100 gm.

• Micronutrients like Zinc, Iron, and Copper are found in appropriate proportion as per analysis.

• During sampling it was observed that microorganisms like earthworm and other annelids were present

in the soil.





• Bulk density is in the range of 1.6 to 1.8 gm/cc and the moisture content of the same soil is in the range

of 20.9 % to 22.2 %.

3.6 ECOLOGICAL QUALITY

Ecology is the science of inter‐relationship of all organisms with their environment. The biotic environment is

organized in to natural groupings with dependence among their members and show varied responses and

sensitivities to external influences. Even if one link is broken the whole system is disturbed. The

developmental activities are one such external influence, which might affect the ecology of an area, if proper

management measures are not taken during construction and operation phases. The following details

describe the terrestrial and aquatic (Marine) ecology of the study area.

3.6.1 Methodology:

Plankton net was used to collect water sample for plankton study & was analysed in laboratory. Beside the

water samples, sediment samples were also collected to study the benthic organisms. Sample from each

location was collected for the study.

Samples for ecological analysis were collected in polyethylene carboys and preserved as per the Techniques

explained by APHA in ‘Standard Methods for Examination of Water & Wastewater’. The sampling location

and details related with the location is given in Table 3.6.1 and Figure of Sediment & Water sampling

Location is given in Figure 3.6.1.





3.6.2 Presentation of Results:

During the EIA study, terrestrial ecology and marine ecology was studied for proposed project of jetty

development at Navlakhi. The outcome of the ecological study and analysis of sediment & water samples,

collected during the study period, are illustrated in following paragraphs.

3.6.2.1 Terrestrial Ecology:

Proposed jetty will be constructed within the Hansthal Creek of Gulf of Kutch near Navalakhi jetty. Hence

there will not be any considerable encroachment in the forestland. Thus the project is proposed to develop

in the marine region. But some of allied activities and set‐up of proposed jetty will have slight influence on

terrestrial ecosystem, especially on the mangrove forest. Some set‐up of jetty is proposed to develop on the

land in the Hansthal Creek near the junction of Sui and Varsamedi creek in the Gulf of Kutch. Overall it is

seen that major proportion of the study area (about 40‐45%) spreads over the seawater area and about 30‐

35 % of the total study area constitutes mudflats/marshy land. Only about 20‐30% of the total study area is

the land portion.

As per the information provided by forest department, study area has about 397 ha of forestland. Prosopis

juliflora, Acacia nilotica and Solanum nigrum are the major floral species observed in the study area. It was

also observed during the field survey that the status of terrestrial forest is not good in the study area. Only

scrub forest consisting of Prosopis juliflora and Acacia nilotica were observed at few places, while rest of the

area is barren. The list of major floral species observed in the study area is given in following table.

Department of Forest has planted some area but the major area of study is out of the range covered by the

Plantation program. However the forest cover around the region is to notice for the study.

3.6.2.2 Marine Ecology:

The proposed site is located at junction of Sui and Varsamedi creek in the gulf of Kutchch. Since, about 40‐

45% of the total study area comprises of marine water body, marine ecology becomes essential for the area.

Excellent growth of mangroves in the Inter‐tidal zone of Gulf of Kutch is very well evident. These marshy,

mud‐covered mangrove lands with significant level of dissolved oxygen provide favourable condition for

growth of variety of marine species. The mangrove swamps are generally productive and on an average

produces about 8 tonnes of organic plant detritus per hectare and fungi, which in turn are eaten by

protozoan. The backwater of mangrove environment forms preferred habitat for breeding and nursery of a

variety of organisms including fishes. As per the records of the Forest Department the inter tidal zone of

Jamnagar and Kutchch forest used to have about 1200 Sq.km. of mangrove forest which consist about 90%

of mangrove vegetation found in the state. Based on the richness of marine flora and fauna 458 sq. km. of

area of Gulf of Kutchch has been declared as marine sanctuary area, which is spread from Okha to Jamnagar

in different patches. A portion of the sanctuary about 163 sq. km. has been notified as marine national park.

But the boundary of marine national park ends at about 30 km west of the project site.





Mangrove vegetation spreaded about 20% of the project study area. However, as per the field observation

most of the mangroves in the area are found to be generally degraded, except a few patches of scrub

vegetation, which is about 2.5% of the study area. The major species of mangrove observed in this area

include Avicennia officinalis and Avicennia marina. The forest department officials at Rajkot and the locals

informed that, there has been a large scale degradation of mangrove forest due to the illegal cutting for the

fuel wood and fodder requirements by local villagers. However on the records of the forest department

Navalakhi area has about 7770 ha of mangrove forest, which has been notified under section 4 of Indian

forest act.

The proposed project site is within the jetty limits of the Navalakhi jetty, which is a developed & notified

jetty as per the notification issued on 21st November in the year 1955. The study area of the project includes

a small portion of mangrove area declared under section 4 and a portion of marine sanctuary. However no

project activity is being envisaged in the sanctuary area. Based on field observations it can be concluded that

the sanctuary area does not have good mangrove vegetation except few patches of scrubby mangrove.

Biological characteristic of a water body are very important as it determines the biological productivity of an

aquatic ecosystem and helps to study the ecological pyramids. Fish production depends on the production of

zooplanktons, whereas the production zooplankton depends on the production of phytoplankton, which is

very well known as primary productivity. Survival and growth of planktons is greatly associated with physico‐

chemical characteristics of the water. Marine water and sediment samples were collected from different

locations and various biological parameters like chlorophyll pigments, primary productivity, phaeophytin,

particulate organic carbon, zooplanktons, phytoplanktons and benthic fauna in the project area were

analysed and are described in the following paragraphs.





A. Chlorophyll, phaeophytin:

The details of Chlorophyll and phaeophytin has been already discussed along with the marine water analysis

report. Chlorophyll and phaeophytin values observed at different stations, as a part of marine survey was

quite low. The results are as below.

1. Sui Creek 1.9 1.7 250

2. Varsamedi Creek 2.3 1.8 430

3. Zammuwadi Creek 3.0 1.6 450

The chlorophyll values ranged from 1.9 to 3.0 mg/m3 and phaeophytin values ranged from 1.6 to 1.8 mg/m3.

The low values can be attributed to the high turbidity and extremely low light penetration. Particulate

organic carbon concentration was slightly better than chlorophyll and phaeophytin. The values of

chlorophyll, phaeophytin are given in table below.

C. Phytoplankton:

Chlorophyll containing Phytoplanktons are the microscopic organisms, which helps to convert the inorganic

carbon to organic through photosynthesis. Thus, the quantity and abundance of phytoplanktons can be used

as an indicator for the primary productivity of any aquatic ecosystem. Phytoplanktons are very sensitive to

organic and inorganic waste and respond quickly to environmental changes. Hence, their standing crop

species composition is more likely indicate the quality of water mass in which they are found. The

abundance of phytoplanktons is dependent on the level of nutrients and light penetration. The zooplanktons





and larvae also feed on phytoplanktons and thus, their survival and abundance is also directly dependent on

the phytoplanktons of the area. Zooplanktons in turn are fed by larvae, juveniles, adult fishes and other

benthic organisms, etc. thus, this inter‐relationship or food chain is directly related to the phytoplankton

abundance.

At various stations, abundance and density of the phytoplankton is given in table below. All the

phytoplanktons belong to diatoms. A total of 17 phytoplankton species of diatoms were observed in the

study area. Cosindicus is the dominant species found at almost all the stations. Other major phytoplankton

species found in the area include Biddulphia sp. and Thallassiothrix sp. The density of phytoplanktons was in

surface water at all the Locations. The highest density of phytoplankton was observed at Location 3, which

was located at the mouth of Varsamadi estuary. Based on the density and diversity of phytoplankton

observed near the site it can be concluded that the area is not very productive.





D. Zooplankton:

Zooplanktons are the important microscopic free floating organisms. Zooplanktons constitute an important

link between primary producer and consumers of higher order in the aquatic food web. Therefore, the

population dynamics of zooplanktons represents the physico‐chemical and biological conditions of water

body. The abundance and density of Zooplankton is given in table below. The important groups of

zooplanktons found in the area are protozoan, Porifers. The highest density (712 number of cells/m3) was

observed at station 3 in surface water and lower (580 number of cells/m3) observed at station 1. Based on

the density and diversity, it can be stated that the site is not very productive. The abundance and density of

zooplanktons depends upon the presence of phytoplanktons in a water body. Density and abundance of

zooplanktons observed in all the stations is very low. Since, the area is not very rich in phytoplanktons,

Zooplankton density and abundance reflects the low productivity, which is not sufficient to sustain good

fisheries potential in the area.

E. Benthic fauna:

Benthic fauna denotes the whole assemblage of organisms dwelling at the bottom. The show marked

diversity depending upon the change in depths and properties of the sediment. The benthic fauna covers

both meio‐fauna and macro‐fauna. As a part of the field studies the benthic fauna was studied at all 4

locations.

The major groups of meio benthos noticed in the area include specules of Holothurians. Pedicileia of Sea

urchin, shell of Gastropods and Foraminifera and fish eggs and larvae. The group Gastropod is dominated at

all the stations. The details of the benthic organisms observed during the field studies are summarized in

table below. The comparative study of density & diversity at all the stations show that the site is not much

productive.

Low density and abundance of benthic fauna is in accordance with the lower values of phytoplanktons and

zooplanktons. Likewise, low primary productivity values also support the lower density and abundance of

meio‐benthos in the area. Therefore, it can be concluded that due to very low values of phytoplanktons,

zooplanktons, primary productivity and benthic organisms, the area is not favourable for good fisheries

potential.

F. Fisheries:

Gujarat, one of the major marine states of India, possessing the longest coastline (1600 km) and

widest continental shelf area. A comparison of the statistical details of the state with the corresponding

figures for the country is as follows:

Continental shelf Area, sq.km 468000 165

Fishing villages, nos. 3355 208

Fishing landing centres, No. 2072 211





Presently the fishing operation of the Gujarat coast is carried out by about 21018 artisanal and

mechanizes/motorized boats and about 4634 medium and small trawlers within the marine water. There

were 13 fishing centres in districts Rajkot. Statistical information on fisheries is given in table below. Major

fisheries activities in these districts have been undertaken in the coastal waters.

The proposed jetty site is about 3.5 Km West of the existing jetty of Navalakhi jetty, which is already in

operation. The fisheries of these areas can be divided into freshwater and marine. However, there are no

fresh water bodies in the study area except for a few seasonal Nallahs and therefore fresh water fishery

does not exist in the study area. About 40‐45% of the study area comes under water bodies i.e. Arabian sea,

which represents varied type of marine fishes. Inspite of the varied type of fish species the area is not rich in

fish production. Navalakhi is the only fish landing centre in the study area. Species dynamics of marine

indicates that Bombay duck is the most common species in this area and contributes to the major catch.

During the field studies no major fishing activity was noticed in the study area. Detailed marine ecological

surveys were also conducted to understand the biological productivity in this area. It

is evident from the physico‐chemical and biological analysis of Marine water and sediment samples that the

values of primary productivity, chlorophyll, phytoplankton, zooplanktons etc. are considerably low and

represents low biological productivity. Likewise fish production in this area is also low. This may mainly be

caused due to high turbidity arising because of marine transport of coal in the region.

The major fish species commonly observed in the study area are given in table below. The maximum landing

is observed between the months of August & September. Generally, flat bottom plank built boat and bag net

locally called ‘Gunja’ are used for fishing. The major fish catch for data was collected from the

commissionerate of Fisheries. Mechanical trollers equipped with gill net were used for the fishing.

The fishery department has also indicated that no active fishing is practiced in and around the project site.

The proposed project area does not appear to be a spawning ground for fishes during the study. Overall

assessment indicates that the estuary has low fisheries potential.

G Crabs:

Specimens of the Scylla serrata (Mangrove crab) were observed during the field survey. Crab species is

common to the muddy areas of mangrove forest. Adult and juvenile specimens of the species were observed

at the site. This leads to the conclusion that the mangrove area could be the nursery ground for this crab.

However, no evidence of the breeding and spawning of this crab species could not be observed during field

survey.





3.7 SOCIO‐ECONOMIC ENVIRONMENT

In order to assess and evaluate the likely impacts arising out of any new or existing projects in Socio‐

economic environment, it is necessary to gauge the apprehension of the people in the surrounding areas.

Socio‐economic survey serves as an effective tool for fulfilling this requirement for sustainable development

in the area.

The geological conditions and natural disaster has great influence on the study region. The disaster of

earthquake of 26th January 2001 has imposed many problems due to the mass destruction caused in the

region. At present there is no residential area in the Navlakhi region. The communities of the area have been

rehabilitated at New Navlakhi (Near Bodki Village). Besides this, there is no official record of any locality

found in the region during the study period. Even the jetty activities at Navlakhi have also been affected

after the disaster together with the socio economic and health environment in the villages. The only

employment opportunity in region is salt work, which is very intensive in the area up to Lavanpur. People of

some villages are engaged with agriculture and to a very lesser extent with animal husbandry. However the

annual return from these activities is very less as the area is highly affected by the salinity, which has

degraded the land in the area. Economic conditions of the local people have become inferior with the

decreasing jetty activity and very low employment opportunities.

The Socio Economic environment includes demography structure, Population density, literacy Level;

employment levels the data establish a baseline for the prediction of likely impacts of the proposed activity

on the socio economic environment.

Secondary information pertaining to the study area villages was collected from Government Agencies,

Census data for the year 2001, and statistical abstracts to compile the socio economic data.





3.7.1 Demography:

Almost all Villages in the Study Area are experiencing a steady –slow growth of population, as the major

study area is restricted for residence. The total Population of study region is summarized in Table: 3.7.1 (a)

Sex Ratio:

The sex ratio is calculated as the number of females per 1000 males. It is in range of 8.7 to 1044.5 in study

region. This implies sociological aspect in relation to female births, infant mortality among female children. A

detail of the same is tabulated in Table: 3.7.1(b) and is represented graphically in Figure: 3.7.1(a).

In Navlakhi, Highest Literacy rate is observed amongst male & female. Among all the villages of study area

Navlakhi is having high literacy rate i.e. 86.08%. The female literacy rate is quite less as compare to male

literacy rate in the study region. Female literacy rate is an important indicator for social change.

3.7.2 Economic Aspects:

Economic aspects of the study area include the economical structure of the people of the surrounding area.

It can be predicted that economic structure of the study area will be improved with time, because it consists

large industrial estate and hence there are more employment opportunities.

According to working status, whole population of the study area is divided into Non workers, Marginal

workers and Main workers.

Census department has defined 10 categories of workers in Main workers. It consists of cultivators,

agricultural, labourers engaged in livestock, forestry, fishing, mining and quarrying, manufacturing,

processing and repairs in household industries and other services.

Workers engaged in the work for a period less than 6 month during the reference year falls under marginal

workers.Workers engaged in unpaid household duties e.g. students, retired person, dependents etc. falls

under non‐workers.

Detail of occupational structure is shown in Table: 3.7.2(a). However it is graphically presented in Figure:

3.7.2 (a). Per capita income & expenditure data is also given in Table ‐3.7.2 (b) for reflection of the socio‐

economic condition in the area.

3.7.3 Amenities:

The study region is lacking of amenities in many socio‐economical aspects. However it can be seen from the

other census data that the lack of significant population and other developmental factors in region has

shown its impacts on the provision of amenities in the region. The detail of amenities in the region is given in

3.8 NOISE ENVIRONMENT

Various activities associated with Industrial development including each stage of site clearance, construction

and operation of installations generate Sound. Sound is perceived as noise when it impinges on human

activities through close proximity of people to sound sources, inadequate shielding etc.

People’s perception of noise varies. It depends on number of factors including their natural sensitivity and

hearing ability, cultural factors and the time of the day at which the sound is experienced. Continuous sound

is perceived quite differently from intermittent sound at the same level. High or continuous noise level may

cause permanent loss of hearing ranging from reduced perception at certain frequencies to total deafness. At

comparatively lower levels noise may have psychological effects including disturbance of sleep, annoyance

and irritation.

The objective of the baseline noise survey is to identify existing noise sources and to measure background

noise levels at the sensitive receptors within the study area (10‐km radius from plant site). Spot noise levels

were measured using a portable Noise level meter.

Noise level was monitored in background region of project site and roads/highways once in a study period.

The exact locations of monitoring station were shown in Figure: 3.8. The noise monitoring results are shown

in Table: 3.8(a).

3.9 CRZ NOTIFICATION CRITERIA

Under the Environment (Protection) Act, 1986, CRZ Rules were declared in order to regulate the

development of industries, operations, and processes in the Coastal Stretches.

3.9.1 Regulation of Permissible Activities:

Notification on Coastal Regulation Zone (CRZ) 1991 (Main Notification S.O .114 E Dated 19th February, 1991

and as amended upto 21st May, 2002) provides for declaring the Coastal Stretches as Coastal Regulation





Zone (CRZ) and regulating activities i.e. imposing restrictions on industries, operations and processes in the

CRZ.

CRZ is defined as all coastal stretches of seas, bays, estuaries, creeks, rivers and back waters which are

influenced by tidal action (in the land ward side) up to 500 m from the High Tide Line (HTL) and the land

between the High Tide Level and Low Tide Line (LTL). The HTL means the line on the land upto, which the

highest water line reaches during spring tide (the HTL shall be demarcated uniformly in all parts of the

country by the demarcating authorities).

The notification provides for construction of jetties, harbour, jetties, wharves, quays, and spillways, under

the following regulations:

• Clearance shall be required for any activity, within the Coastal Regulation Zone only if it requires water

front and foreshore facilities.

• The clearance is required from the Ministry of Environment and Forests, GOI for operational

constructions for jetties and harbours and light houses and constructions for activities such as jetties,

wharves, quays and spillways, and also for activities with investment exceeding Rs. 5 Crores.

According to the coastal area classification and development regulations the proposed project falls in the

following classification category:

• Category I (CRZ I)

(i) Ecologically sensitive and important areas are declared by the Central Govt. or the concerned

authorities at the State / Union Territory levels time to time.

(ii) Area between the LTL and HTL





• Category III (CRZ III)

Areas those are relatively undisturbed and those which do not belong to either Category I or II will include

coastal zone in the rural areas (developed and undeveloped) and also areas within Municipal limits or in

other legally designed urban areas, which are not substantially built up.

The proposed project is not going to add any additional pollutants but will add significantly to the company’s

efficiency and productivity. Therefore, the project has a strong justification and will enable the company to

further excel in the export performance, which is very vital for the country as it will earn very good foreign

exchange for the country.

The map showing CRZ boundaries for proposed jetty project is shown in Figure: 3.9

3.10 LAND USE

Proposed jetty will be constructed within the Hansthal Creek of Gulf of Kutch to the west of Navalakhi jetty.

The project is proposed to be developed in the marine region but some of allied activities and set‐ups of

proposed jetty will be developed on the land in the Hansthal Creek near the junction of Sui. The study area

mainly comprises of sea and land. The land portion is predominantly plain. Overall it is seen that major

portion of the study area (about 40‐45%) spreads over the seawater area and about 30‐35 % of the total

study area constitutes mudflats/marshy land. Only about 20‐30% of the total study area is the land portion.

Land use classification of the study area is presented bellow in the Table 3.10 and in Figure 3.10.

The detailed description and explanation of different land use and land cover categories, seen in the study

area, is discussed below.

3.10.1 Water Bodies:

Creeks are found as the major water bodies in the study area. River basins in the study region were not

found but some ponds and lakes were found in the study region & extended regions.

3.10.2 Mud Flat:

Mud Flat is the second other major subcategory in the study area. It comprises of soft clayed mud due to

high water table and has a flat topography. This area is mainly submerged during high tides and therefore

serves as an ideal habitat for the growth of seaweed, coastal swampy and marshy vegetation.

3.10.3 Mangroves:

The study area of the project includes a small portion of mangrove area and a portion of marine sanctuary.

However no project activity envisaged in sanctuary area. Based on satellite data and field observations it can

be concluded that the sanctuary does not have good mangrove vegetation except few narrow discontinuous

patches of scrubby mangroves.

3.10.4 Vegetation and Scrub:

The samples were collected as per the information provided by forest department. Study area has about 397

ha of forestland. It was also observed during the field survey that the status of terrestrial forest is not good

in the study area. Only scrub forest consisting of Prosopis juliflora and Acacia nilotica were observed at few

places, while rest of the area is generally barren. Department of Forest has planted some area but the major

area of study is out of the range covered by the Plantation program. The total reserved forest cover on the

record of Department of forest is Varsamedi ‐114.93 Ha, Bodki ‐121.41 Ha., Zinzuda ‐ 20.64 Ha., Fadsar ‐

80.94 Ha. and Bela ‐58.54 Ha. which is in aggregate being 396.46 Ha.





3.10.5 Agricultural Land:

Cropland occurs in small patches in the eastern corners of the study area. The major crops cultivated are

wheat, paddy groundnut etc. As there is no source of irrigation, agricultural activity is totally dependent on

rain water.

3.10.6 Settlements:

It is the area of human habitation.It was observed that there is very spars human settlement in the area

surrounding the project site. Few settlement were noticed in Navlakhi, Lavanpur, Varsamedi and Bodki. The

human habitation area is included as built‐up land. Apart from this the built‐up land also includes harbour,

jetty, jetty go downs, jetty administrative buildings etc.

3.10.7 Salt Bed:

The salt pan develops due to arid climate and due to high rate of encrustation and deposition of salt by the

tidal water. This occurs in patches in the southern, western and eastern parts of the study area. However

major salt pans are located in the eastern and southern shores. The major salt pans located in the study

region are Chowgule and Maharaja salt works.

3.10.8 Barren Land (Waste Land):

The important land cover falling in the study area is barren land wasteland. Wasteland is presently barren

and currently unutilised because of lack of water and soil management.
