C onservation and sustainable

management of natural resources

are fundamental to sustainable food

production, water supply and livelihoods.

Natural resources such as land,

biodiversity, water, livestock and soil

are being continually exploited by

human societies, often leading to the

degradation of these resources. Village

ecosystems are complex systems with

inter-linkages between natural resources

and livelihoods of communities.

The state of environment and natural

resource report of a village focuses on

major natural resources, their status and

trends over the years and also the

inter-linkages. With this understanding,

the report highlights key environmental

issues with implications for resources,

livelihoods and sustainability. To

understand the status of and trends in the

resources, indicators were identified and

an inventory of the natural resources

carried out. The agro-ecological zone

(AEZ) approach was adopted in

selecting the vil lage, taking into

consideration the key features of the

selected AEZ and the representativeness

of the vil lage. This facilitates

understanding of the strata of the sub-

AEZ in which the village is located. This

report serves as a model and has been

generated adopting the indicators and

methods developed by the Indian

Institute of Science for monitoring

natural resources.

The report presents general information

of the vil lage in the initial section.

Subsequent sections systematically

address the status of various resources,

and the final section concludes with a

synthesis of the findings, which identify

inter-linkages of various resources and

environmental issues.

1. Introduction

1.1. Utility of a State of theEnvironment Report

This state of village environment report

is important to the following entities:

l Village communities including

farmers and particularly women to

assist them in decision-making on the

use and management of natural

resources.

l Policy-makers at regional, state and

national level to help them design

strategies and policies to conserve

natural resources.

l Distr ict/block/panchayat-level

planners and decision-makers.

l Development departments such as

forests, agriculture, pasture

development, water resource, and

the environment to promote

sustainable practices.

l Educational institutions to create

awareness.

1.2. Agro-Ecological ZoneApproach

India is a large country with diverse

temperature, rainfall, soil, vegetation

and socio-economic conditions. AEZ

categorization is based on the length of

the growing period (LGP), which is

derived from climate, soil and

topography data using a water balance

model and knowledge of crop

requirements. The AEZ approach is

adopted by FAO and other agencies

for all forest, cropland and other

land-resource-related planning

activities.

India has been divided into 20 AEZs based

on rainfall, moisture and temperature

regimes, soil type, land form, etc.

Page 7: Kempanaickenapalayam Village Ecosystem

2

The AEZ and village ecosystem approach

is adopted in this study for the following

reasons:

l AEZ is widely used by the Planning

Commission, the Ministry of

Agriculture, National Bureau for Soil

Survey and Land-Use Planning,

agricultural universities, and others.

l A strong functional

interdependence exists among

the natural resources (forests,

watersheds, grasslands, water

bodies, livestock and cropland) at

the village environment level in

each AEZ.

l Decision-making on the use and

management of natural resources

such as forests, biodiversity, grazing

lands and irrigation water occurs at

the village environment level.

l Participatory institutions such as

water sanghas, forest protection

committees and biodiversity

management committees are

organized and function at the

village level.

l Overlaying the natural ecosystem

boundary of an AEZ with

administrative boundaries gives a

unique combination of physical,

biological and socio-economic

perspectives.

1.3. Village Location

l Kempanaickenpalayam village is a

part of Sathyamangalam taluk of

Erode district of Tamil Nadu

(Figure 1).

l Kempanaickenpalayam is located

at 11°312 45.03 N and 77°182 023

E 254 m above the mean sea level.

The vil lage is 10 km from

Sathyamangalam, the nearest town

and the taluk headquarters.

l The village falls under the agro-

ecological sub-zone AEZ 8.3, the

Tamil Nadu uplands and plains of

India and is characterized by hot

moist semi-arid climate and deep

red loamy soil.

1.4. Reason for SelectingKempanaickenpalayam

l Kempanaickenpalayam is an

agricultural village situated at the

foothil ls of the Eastern Ghats

and presents a unique set of

bio-geographical features.

l Very few efforts have been made

in the past to monitor the natural

resources.

l Land survey to demarcate and map

different land-use systems as well as

estimate the area under each to

enable comparison with past data

and to understand changes in land-

use pattern.

l Household survey to obtain

information on cropping pattern,

water sources, fuelwood

catchment area, consumption

pattern, etc.

l Field measurements to estimate

biomass in different vegetation

types, fuelwood, water

consumption, dung production by

cattle and assessment of fish

resources and diversity.

l Laboratory measurements to

measure the quality of drinking

water and the status of soil quality

in terms of soil organic carbon.

l Participatory Rural Appraisal (PRA)

to gather detailed and qualitative

description of village resources,

patterns of use, trends and changes

in the status of resources over the

years.

1.7. Monitoring Period

l The study was conducted during

September 2006 to March 2007

(referred to as "the Current" period).

l The land-use and crop particulars

are for the major cropping season,

namely kharif (October to January).

1.5. Natural ResourcesMonitored

The resources monitored in

Kempanaickenpalayam vil lage

ecosystem include:

l Demography: Population and land

holding pattern.

l Climate: Rainfall pattern.

l Land Resources: Cropland,

wasteland, agro-forestry and

plantations.

l Livestock Resources: Population,

breeds, grazing pattern and dung

production.

l Water Resources: Rivers, canals,

wells and drinking water sources.

l Soil Resources: Organic matter

status.

l Wildlife: Large mammals and birds.

l Fish Resources: Diversity,

production and consumption

patterns.

l Settlements and Infrastructure:

Sanitation, electrification status,

schools, housing areas and roads.

1.6. Methods Adopted

The following methods were adopted to

assess the status of various resource and

resource indicators.

l Secondary records for data on

rainfall, population, land-use

pattern, livestock, etc.

2. Demography and Rainfall

2.1. Demography

2.1.1. Population and Land Holding

l The national census conducted in

2001 recorded a population of

6,551 comprising of 3279 males and

3272 females.

l The total number of households is

979.

l Landless agricultural labourers

dominate, and account for 51% of

the total households.

l About 12% of the households are

those of medium farmers with

2.5 to 5.0 acres of land; only 1% of

the households own more than

5 acres of land (large farmers).

l Small farmers (those with less than

2.5 acres of land) account for 8% of

the households (Figure 2).

l Non-agricultural occupations

include weaving (15%) and basket-

making (5%).

2.1.2. Trends

l The population of

Kempanaickenpalayam has

increased over the last few

decades.

2.2. Climate: Rainfall

2.2.1. Current

l The mean annual rainfall of Erode

district is 660 mm.

l The mean annual rainfall of

Sathyamangalam taluk is 769 mm

(average of 70 years).

l The rainfall recorded during 2006

was about 757 mm.

l As Kempanaickenpalayam lies on

the leeward side of the Western

Ghats, it receives most of its rain

from the retreating northeast

monsoon, September to November

being the peak months (Figure 3

and 4).

In Kempanaickenpalayam, the

communities utilize the forest for their

livelihood activities such as grazing and

collection of fuelwood. About 50

families depend on basket-making, using

bamboo collected from the forest.

About 200 families were dependent on

this occupation until a few decades

ago. Gradually, the number decreased

due to the low income from this

occupation and reduced availability of bamboo because of over extraction.

During the participatory rural appraisal process, members from the basket-making

community stated that earlier they used to extract 3.7 tonnes of bamboo a day.

But now, they extract only about one tonne. Due to overexploitation and

deforestation, bamboo production in the forest has decreased and the number

of households involved in basket-making has declined to one-fourth of that in

the earlier years. Further, market demand

for bamboo baskets has also reduced.

This occupation may become extinct in the

next few years, because the younger

generation of this community is now shifting

to other occupations because of the

difficulty in collecting the bamboo from

the forest and the declining market for

baskets.

records maintained at the vil lage

administrative office (Figure 5).

l Cropland: Area under crops

decreased gradually from 570 ha to

501 ha (8%).

l Fallow land: Area under fallow land

increased substantially from 99 ha

in 1997 to 165 ha in 2006 (Figure 6).

3.1. Land Use

Kempanaickenpalayam shares its

northern and eastern boundaries with a

state-owned reserve forest; on the west,

it is bound by Kondappanaickenpalayam

village and to the south, by Sellipalayam

village. A stream, named Perumpallam,

flows across the village from the north

to the south. This stream is a major

source of water for the Perumpallam

dam, a small dam north of

Kempanaickenpalayam. The human

settlements are located in the southern

part of the village.

3.1.1. Current Land Use

The total geographic area of

Kempanaickenpalayam is 923 ha. The

major land-use components include

settlements, infrastructure, wasteland,

cropland and fallow land.

l Currently, cropland accounts for

501 ha.

l About 224 ha of land is under water

bodies such as dam, streams and

canals.

l About 91 ha of cultivable land is

fallow.

o currently, 74 ha of land is

permanent fallow, and has not

been cultivated for the

preceding five seasons.

l Settlements including homes and

sites account for 22 ha.

l Roads and infrastructure occupy

about 11 ha.

3.1.2. Trends in Land-use (1997–2007)

Trends in major land-use over the

decade are discussed in this section

based on information compiled from

l Sugarcane is the dominant crop,

accounting for 150 ha, about 30% of

the total cropland area (Figure 9).

l Other crops include vegetables,

mulberry, flowers and bund

plantations.

l Food crops such as paddy and pulses

account for less than 15%.

3.2.2. Trends in the Cropping Pattern

l There have been significant

changes in area under cash crops,

cereals, pulses and fodder crops in

Kempanaickenpalayam.

l Area under cereals such as paddy

and maize have drastically

decreased (75%) over the decade

from about 213 ha in 1997 to 53 ha

now.

l Area under pulses shows a trend

similar to that for the cereals and

decreased from 45 ha in 1997 to 16

ha in 2007 (Figure 10).

l Cash crops, on the other hand, show

a reverse trend of increasing area

(Figure 9): area under cash crops

increased from 199 ha to 324 ha

(30%).

o sugarcane cultivation in

particular increased

substantially, from 60 ha in 1997

to 150 ha now.

3.1.3. Factors Contributing

l The prime reason for the decrease

in cropland area is water shortage.

o change in cropping pattern

from short-duration to annual

crops such as sugarcane and

turmeric has increased the

demand for water

o with the availability of water

remaining constant, the fallow

land area has increased.

3.1.4. Implications

l Increase in fallow land has

increased the land available for

grazing.

l Loss of cropland leads to

decreased agricultural activity and

production.

l Landless labourers are forced to

seek employment in non-farm

activities and out migrate as a

result of decreased agricultural

activity.

l Loss of fertile cultivable land.

3.2. Cropping Pattern

3.2.1. Current Cropping Pattern

l Cash crops dominate the cropping

pattern (65%).

o cash crops include sugarcane,

turmeric, banana, tobacco

and coconut.

l Food crops and cereals account for

15% and 11% respectively.

l The major irr igated crops are

sugarcane, turmeric, banana,

tobacco and vegetables (Figure 7

and Figure 8).

l The major rainfed crops include

fodder maize, tapioca, bajra and

pulses.

l There is also a drastic reduction

(13%) in fodder cultivation from 161

ha in 1997 to 77 ha now (Figure 11).

3.2.3 Factors Contributing

l Assured market for sugarcane

due to establishment of the

Bannariamman sugar factory in

1986 in the nearby Sathumugai.

l Increased availability of water due

to increase in number of borewells

from none in 2000 to 47 in 2006.

l The people’s perception is that the

construction of Perumpallam dam

in 1992 has helped to maintain the

level of groundwater.

l The increase in irrigated area has

replaced crops with lower

monetary value. In addition, area

under cultivation of long-duration

crops such as sugarcane, turmeric

and banana has increased.

l Lesser human effort needed and

high returns from tapioca compared

to other rainfed crops such as bajra,

pulses and fodder maize.

3.2.4. Implications

l Increased cultivation of water-

intensive crops l ike sugarcane

could increase the number of

borewells in the vil lage and,

consequently, would lower the

water table in the long-run.

l Increased production of cash crops

has increased the monetary returns

from land.

l Decreased production of fodder

crops has resulted in fodder being

in short supply. This has increased

the grazing pressure on the forest.

3.3. Crop Varieties

3.3.1 Current

l Sugarcane variety currently under

cultivation is TC353.

l Paddy varieties currently under

cultivation are ADT43, ADT38, and

CO43.

l Tapioca variety under cultivation is

MVT1 (Mulluvadi).

l Fodder maize varieties grown are

CO25 and BSR1.

l BSR1 and BSR2 are the two varieties

of turmeric.

l Bajra varieties include ICMS 7703,

K4 and CO7.

l Tobacco varieties grown in the

village are I115, VTK1 and vairam.

l Traditional variety of onion is grown

in the village.

Kempanaickenpalayam is a semi-arid

village in Erode district. The village has a

seasonal stream, named Perumpallam,

from which the village gets water during

the rainy season; for most of the year, the

stream is dry. The district authorities

decided to construct a small dam across

the Perumpallam stream. The plan for the

construction of dam was first prepared in

1985; construction began in 1988 and the

dam was completed in 1994.

Perumpallam dam is located in the

northern part of the village. The size of the

reservoir is about 442 acres, including a

small part from the neighbouring village

Kondappanaickenpalayam.

The dam has the capacity to irrigate 450

acres of land of which 339 acres are in

Kempanaickenpalayam. Initially, the stored

water was used directly for irr igation.

However, since the water did not last for

more than 40-50 days (not even adequate

for a short-term crop like onion), the village

administration decided to store the water

and use it as a percolation tank. The dam

serves to recharge groundwater and is used

for fish culture.

The construction of the dam has

changed the cropping pattern of the

village. After construction of the dam,

the number of open wells and

borewells has increased considerably,

thereby increasing the irrigated area.

Although sugarcane, turmeric and

banana are the traditional crops,

people started cultivating these

crops extensively after the

construction of dam.

l MCU5 and jayalaxmi are the

varieties of cotton.

l Banana varieties currently under

cultivation include robusta,

poovan, rasthali and GENE9.

l T9 is the variety of black gram.

3.3.2. Trends in Crop Varieties

l Until about two decades ago, only

traditional varieties of crops were

cultivated.

l The same varieties of banana have

been cultivated except GENE9 in

the past several years.

l No traditional variety of sugarcane

is grown in the village.

l Sugarcane variety CO8021 was

grown in the past years.

l IR20, CO46, ADT36 were the

varieties of paddy cultivated in the

past decade.

l I115, VTK1 were the varieties of

tobacco, grown earlier.

l MCU12, DCH were the varieties of

cotton cultivated in the past

decade.

3.3.3. Factors Contributing

l The loss of traditional varieties is

due to the extension and promotion

by the agricultural department for

cultivation of improved varieties.

l Changes in market forces and food

habits have contributed to shifts in

crop varieties.

3.3.4. Implications

l Loss of traditional varieties.

l It is feared that the introduced

high-yielding varieties may be more

sensitive to the local pests and may

require application of fertilizers.

3.4. Crop Yields

Majority of the farmers reported a

reduction in the yield of crops over the

years despite shift to high-yielding

varieties and application of fertilizers.

l A large number of farmers cultivating

sugarcane report a decrease in yield

over the last five years.

l An overwhelming 73% of farmers

reported a decrease in turmeric

yield over past five years.

l Farmers growing banana had a

mixed response. While 37%

reported decrease in yield, 26%

reported an increase in the yield

and 37% reported no change.

3.4.1. Factors Contributing

l Incidence of mealy bugs in

sugarcane has affected the yield.

l Decrease in the yield of turmeric

may be due to leaf mites.

3.4.2. Implications

l Increased use of ferti l izers and

pesticides has implications for soil

fertility in the long-run.

3.5. Fertilizer and ManureApplication

3.5.1. Current Use

l Participatory rural appraisal of

farmers revealed increased use of

synthetic fertilizers and decreased

use of organic manure (Table 1).

l Irrigated crops such as sugarcane,

turmeric and paddy are grown using

high input of synthetic fertilizers (1.3

to 1.7 t/ha) along with significant

amount of organic manure (20 to

28 t/ha).

l Rainfed crops such as fodder maize,

bajra, tapioca are not supplied with

Page 18: Kempanaickenapalayam Village Ecosystem

13

any synthetic fertilizer (Table 1).

Some farmers use organic farmyard

manure for tapioca (20 t/ha).

l For pest control, farmers in the

vil lage take the advice of the

vil lage agricultural officer and

use pesticides such as

monocrotophos, borate,

dimethoate, butachlor and

endosulphan.

3.7. Agro-forestry

3.7.1. Current

Cropland bunds

l Most farmers practise agro-forestry

by growing trees along their

cropland bunds.

l There is no block plantation of trees.

l A total of 28 species were recorded

along the cropland bunds.

l Coconut is the dominant species

with an average density of 12 trees/

ha. It accounts for 84% of the total

tress along the bunds (Figure 12).

3.5.2. Implications

l Reduction in organic manure,

particularly the disappearance of

the practice of raising a green-

manure crop, over the years may

adversely affect soil fertility and

sustainability of crop yields.

l Excess application of synthetic

fertilizer may lead to increased

salinity of the soil and depletion of

soil biota.

3.6. Pests and Use of Pesticides

l Nearly 30% of the farmers growing

paddy recorded the following pests:

o stem borer, leaf roller, thrips

l Over 50% of the farmers cultivating

sugarcane reported the following

pests:

o mealy bug, white fly

l Turmeric: Thrips are the major pest

reported.

l Tobacco: Cut worm and stem borer

are the major pests reported.

l Banana: Wilt was the major disease.

l Other major species include silk

cotton, neem, areca nut, lemon,

teak, mango and several species of

Acacia.

Roadside vegetation

l The 4-km stretch of road through the

village occupies about 9 ha.

Prosopis - Bane to Boon

Prosopis sp. is a weed of national

significance. It is regarded as one

of the worst weeds in India because

of its invasiveness, potential for

spread, and economic and

environmental impacts.

Prosopis originated in Argentina and

spread all over the world. Prosopis

is known to have spread in India

since the 1870s by migrant animals;

first identified in Andhra Pradesh, it

has spread all over the country.

The economic impacts stem from its habit of forming dense, impenetrable

thickets that, combined with its thorns, prevents cattle from accessing watering

holes and makes grazing difficult. Prosopis also reduces the productivity of

grazing land by covering the ground and using valuable soil and water resources.

Other impacts of Prosopis include damage to animal hooves and the poisoning

of livestock, when they consume excessive amounts of its pods.

Environmental impacts, once the species becomes dominant, include changes

in soil quality, which make the soil incapable of supporting native plants and

animals, and safe refuge for feral animals such as pigs and cats.

In Kempanaickenpalayam, Prosopis was observed in the late 1960s as a

multi-stemmed thorny shrub. In Kempanaickenpalayam, Prosopis infestation is

spread over about 150 ha.

At Kempanaickenpalayam, Prosopis sprouts rapidly after the retreating monsoon.

Dark vegetal growth is found along the stream bunds flowing from the

Perumpallam and in the low-lying areas of the region, community land and other

wastelands. It has now become an aggressive weed in Kempanaickenpalayam.

The invasion by Prosopis of agricultural land affects agriculture in the region.

Landowners fear that its growth could reduce crop and livestock production,

and farmers do not allow the shrub to grow in the immediate vicinity.

However, thanks to the thorny shrub's ability to withstand harsh conditions, some

farmers in Kempanaickenpalayam have used Prosopis as a live fence around

their land to protect their crops from the cattle. Because of its ability to

regenerate rapidly, the shrub is looked upon by many as an inexhaustible fuel

source. Many landless people in Kempanaickenpalayam completely rely on it as

their principal fuel source for domestic use. Over 500 households in

Kempanaickenpalayam depend on the shrub as their principal fuel source.

l A total of 14 different species were

recorded along the roadside.

l Neem was the dominant species

(39%) along the roadside (Figure 13).

l Silk cotton and Cassia species

make up 25% and 15% of the total,

respectively.

Stream-side vegetation

l The total area of streams is 73 ha.

l About 25 tree species were

recorded along the Perumpallam

stream that runs through the

village carrying water from the

Perumpallam dam.

l Silk cotton was the dominant

3.7.2. Trends in Agro-forestry

l Coconut dominates the cropland

bunds while multiple naturally

regenerating trees dominate the

banks of the stream and the

roadside.

l Over 30 different species were

recorded in the village along the

bunds of cropland, streams and

roadsides.

l Out of these, only 10 species are

planted; the rest are naturally

regenerated and retained.

l According to the participatory rural

appraisal involving senior members

of the society, a large variety of

trees were found few decades ago,

and these have dwindled.

This means a loss of biodiversity in

agro-forestry.

3.7.3. Factors Contributing

l Market forces have motivated the

farmers to cultivate coconut along

cropland bunds.

l Income from the minor forest

produce such as neem seeds

and fibre encourages farmers to

protect the vegetation along

the banks of the stream bunds and

the roadsides.

3.8. Grazing Land - Fallow landand Stream-side

3.8.1. Current Grazing Land

l No dedicated grazing land is found

in the village; therefore, the fallow

land and the stream bunds are used

for grazing, supplemented with stall

feeding.

l The total area under fallow land is

165 ha.

l The streams accounts for about

73 ha.

Page 21: Kempanaickenapalayam Village Ecosystem

16

l With the increase in l ivestock

population, grazing pressure on the

already meagre grazing area in the

village is increasing.

3.8.2. Trends in Area Available for

Grazing

l The area under fallow land in the

past decade has increased by 4%

(Figure 15).

l The cropping pattern has seen the

low productive lands being

abandoned, leading to increase in

the area under fallow land.

3.8.3. Implications

l Due to the lack of grazing land,

livestock are grazed in the forest

over the past years and because

of livestock grazing, the vegetation

in the forest is subjected to

degradation.

4.1.2. Trends in Livestock Population

l The population of milch animals

increased from 835 in 1997 to 945 in

2006 (Figure 17).

l The population of sheep and goats

also increased over the past

decade, from 3415 in 1997 to 4060

now (Figure 18).

4.1.1. Current Livestock

l Currently the livestock population

of the village is 5306.

l Sheep and goats dominate (77% of

livestock population) and number

4060.

l The number of milch animals is

945, 18% of the total l ivestock

population (Figure 16).

l The number of bullocks is about 185

(3%).

l People switched from traditional

breeds to crossbreeds in the 1980s,

following advice from the local

dairy units.

l Participatory rural appraisal

revealed most cows now reared

are crossbreds: the traditional

breeds account for less than 30%.

4.1.3. Factors Contributing

l The traditional breeds are being

replaced with crossbred animals

because the latter give more milk.

l Stall-feeding has increased due to

increase in the number of crossbred

cows.

l Establishment of a small-scale dairy

in the village and the market it

offers have driven people to opt for

crossbred milch animals as they

give a higher yield.

l Bullocks are replaced by the

tractors for ploughing due to the

human effort involved in rearing

bullocks.

l The increase in sheep and goats

population appears to be linked

with the decline in rainfall over the

past many years.

4.1.4. Implications

l Loss of traditional breeds.

l Increase in the population of sheep

and goats and grazing them in the

nearby forest land have adversely

affected the regeneration

capacity of the forests.

l The high grazing density is leading

to degradation of fallow land.

4.2. Dung Production

l Only 3% of the households have

biogas plants.

l Average production of dung is

10 kg/cow/day .

Page 24: Kempanaickenapalayam Village Ecosystem

5.1. Irrigation Water

5.1.1. Current Availability

l Borewells and open wells are the

two sources of irrigation.

l Before the 1990s, the only source of

irrigation was open wells.

l In the 1990s, the farmers started

drilling borewells.

l Now there are about 47 borewells

and 247 open wells within the

village.

l The Perumpallam and other streams

that pass through the village serve

as a seasonal source of water but

are not available for irrigation.

l The Perumpallam dam has the

capacity to irrigate about 340 ha

of cropland, but the local

community along with the PWD has

taken a decision not to open the

dam for irrigation, as there are no

perennial sources of water for the

dam.

o the Perumpallam dam at

present is used mainly as a

percolation tank to recharge

the groundwater.

5.1.2. Trends

l Irrigated area has increased in the

recent years.

l In 1997, the total area under rainfed

farming was 339 ha; now it has

decreased to 185 ha due to the

increase in irrigation sources.

l There is a significant increase in the

number of open wells from 63 in

1978 to 247 in 2006.

l There were no borewells in 1978 and

in 2002 there were 4 borewells and

currently there are 47 borewells, a

91% increase over the period 2002

to 2006 (Figure 19).

5. Water and Soil

5.1.3. Factors Contributing

l Construction of the Perumpallam

dam has helped recharge the

groundwater in the village.

5.1.4. Implications

l Free electricity supply by the state

for agriculture has encouraged the

use of borewells. The free supply has

made both the digging of wells and

pumping water from them more

economical than is the case with

open wells.

l Increase in the number of borewells

may lower the water table; the

average depth of borewells is

already 650 feet, indicating the

decline.

5.2. Drinking Water

5.2.1. Current Water Sources

l Taps, hand pumps and open wells

are the main sources of drinking

water in the village.

l One part of the vil lage is also

served by a reservoir.

5.2.2. Current Water Quality

l All the parameters except turbidity

(30 NTU) were within the permissible

limits in samples from the reservoir.

l In all other samples, total dissolved

solids (TDS) and alkalinity exceeded

the desirable limits (TDS shows the

hardness of water) but was within

the permissible limits (Table 2).

l Samples from open wells and hand

pumps were found to have slightly

higher concentrations of nitrate

than the desired limit, but all were

within the permissible limit.

5.2.3. Contributing Factors

l Hardness can be due to the

presence of salts of calcium and

magnesium.

l TDS and total alkalinity may be

attributed to the geological

reasons.

5.2.4. Implications

l Water with high dissolved solids will

be usually turbid. It does not have

any implications for human health,

but lowers the consumption of

water by imparting a disagreeable

taste to the water.

l Hard water, although it does not

have any implication for health,

makes the water salty to taste,

thereby lowering the quality of

water and making it less suitable for

cooking and washing.

5.3. Microbial Load

5.3.1. Current

l All the samples from borewells and

the reservoir were free from

coliform bacteria.

l A third (33%) of the open well

samples, 65% of the tap samples

and 78% of hand pump samples had

their total coliform count within

the permissible limits (0–10 MPN/

100 ml). (MPN is the most probable

number.)

l Nearly half (48%) the samples from

open wells and roughly a fifth (22%)

of those from hand pumps had a

total coliform count ranging from

11 to 100 MPN/100 ml.

l In 14% of open well samples, the

total coliform count ranged from

101 to 200 MPN/100 ml.

l A very small proportion (5%) of

the open well samples had a

microbial load greater than 500

MPN/100 ml.

Page 26: Kempanaickenapalayam Village Ecosystem

21

l Tapioca, turmeric and tobacco

had 0.59, 0.64 and 0.54% organic

carbon, which indicates highly

fertile soils.

5.4.1. Implications

l Lands in which perennial crops are

grown have high organic carbon.

l Soil ferti l ity status is poor on

croplands and high on fallow and

forest land, where the topsoil is not

disturbed.

Turmeric 0.64

Tobacco 0.54

Forest 0–15 cm depth 1.58

5.3.2. Contributing Factors

l Presence of coliforms in open wells

can be due to contamination by

birds, rotten leaves and faecal

matter.

l Contamination of water from the

hand pumps can be attributed to

improper methods of sewage

disposal and poor sanitation.

5.3.3. Implications

l If the water contains pathogenic

bacteria, r isk of waterborne

diseases is likely to be high.

5.4. Soil Quality

l Sugarcane, banana and tobacco

are the major crops in the area.

l Fodder maize is grown as a dryland

crop and it had 0.43% organic

carbon in the soil (Table 3).

l Soils in bajra crop had the least

organic carbon of all the crops

(0.23%).

l Fallow land had 0.75% organic

carbon whereas forestlands had

1.58% in the topsoil and 1.38% at

15–30 cm depth.

The northern and eastern boundary

of the vil lage borders with the

Sathyamangalam reserve forest. Many

wild animals from the forest often make

their way into the vil lage. The

construction of the dam across the

Perumpallam stream has increased the

frequency of sighting of animals such as

elephants.

6.1. Birds

6.1.1. Current

Several woodland birds were sighted

during the study throughout the village

and more near the crop fields. The list of

woodland birds sighted in the village is

listed in Table 4.

l Wetland birds are limited to the

area around the Perumpallam dam

and irrigated crop fields. Villagers

report that large number of

migratory wetland birds like the

teals flock around the Perumpallam

dam.

l Migratory birds are sighted

between September and March.

l Listed below are some of the

common wetland birds sighted in

the village (Table 5).

6.1.2. Trends

l The population of wetland birds has

increased after the construction of

the dam.

l The population of woodland bird is

gradually decreasing due to the

change in the cropping pattern.

(e.g., decrease in the area of

cropland).

6.2. Mammals

6.2.1. Current

Large mammals are sighted in the

northern and eastern part of the village,

Page 28: Kempanaickenapalayam Village Ecosystem

23

especially in the Perumpallam dam

area and the hills of Madheswaran,

Malli Amman and Narayanan

(Karumalai).

l Among mammals, wild boar, rabbit,

spotted deer, elephant, civet cat,

wild dog and a few rodents are

some of the commonly sighted

species in the village area.

l Listed below are common

wild animals seen in the

Kempanaickenpalayam region

(Table 6).

Panther

6.2.2. Trends

l The frequency with which the

animals enter into the fields has

increased due to the changes in

the cropping pattern. (e.g.,

cultivation of tapioca and

sugarcane attracts wild boars and

elephants).

6.2.3. Implications

l The change in the cropping pattern

has an impact on the wild animal

population.

o wild boar has become a serious

pest to sugarcane, tapioca and

other crops. Their attacks on

the crops has reduced yield in

the recent years.

l The diversity of bird population

(specially the migratory birds) in the

village has increased.

Page 29: Kempanaickenapalayam Village Ecosystem

24

6.3.2. Trends

l All water bodies are a seasonal

source of fish but with the

construction of the dam in 1994, the

storage capacity has increased

considerably and the water bodies

now serve as a source of less

commercial pisciculture.

l Seven fish species have

disappeared, namely Channa

maurilius, Channa striatus, Channa

puctatus, Clarius dussumieri,

Channa nama, Applocheilus

lineatus and Cirrhinus reba.

l Fish yield has decreased in all the

water bodies. Four yeas ago,

according to the fish contractors,

fish yield used to be 15 to 20 quintals

per year; now, it is only 3 to 4 quintals

per year.

l Earlier, the number of fishermen was

27; now, due to the reduction in the

fish catch, the number has dwindled

to 7; the rest have opted for other

livelihood options.

l The reservoir was 35 feet deep in

1994. The depth has decreased

considerably due to siltation and

currently stands at 25 feet,

affecting fish growth and yield.

6.3.3. Factors Contributing

l Cereals and fodder crops are grown

on the reservoir bed during the dry

season. The pesticides used in these

fields run off into the reservoir and

affect fish production.

6.3. Fish Resource

6.3.1. Current Status

l Fishing is done in the reservoir,

streams and canals of

Kempanaickenpalayam.

l The checkdam is used for private fish

culture.

l The predominant fish species in

reservoir include catla (Catla

catla), common carp (Cyprinus

carpio), rohu (Labeo rohita),

mrigal (Cirrhinus mrigala),

velichimean (Salmostoma

sardinella) and tilapia (Oreochromis

mossambicus).

l In the streams (downstream of

the reservoir), 8 species were

recorded; the predominant

fish species include loaches

(Lepidocephalicthyus guntea)

and ti lapia (Oreochromis

mossambicus).

l In canals, 7 species were

recorded; the predominant fish

species include Oreochromis

mossambicus, pool barb

(Puntius sophore) and loaches

(Lepidocephalicthyus guntea).

l Nearly all (98%) the households in

the village eat fish.

l Every time the water level in the

dam is low, farmers encroach

upon the area for agricultural

activities. Crops such as tapioca,

fodder maize and bajra are

cultivated.

Page 30: Kempanaickenapalayam Village Ecosystem

7. Energy and Sanitation

7.1. Energy Sources

7.1.1. Current

l Nearly 30% of the households have

improved stoves.

l A large number of these (over 75%)

were installed in the last 5 years.

l Over 20% of these stoves were

installed in the 1980s and 1990s.

l Only 13% of households have a

chimney for their cookstoves.

l Nearly 30% of households have LPG

stoves.

l Fuel savings of 5–15% have been

reported in 27% of the households.

l About 3% of the households own a

biogas plant.

l All biogas plants were installed in

the late 1980s and early 1990s.

l The biogas plants in the village are

large and have an average

capacity of 9 cubic metres.

l An average of 25 kg of dung is used

for each biogas plant per day.

l Biogas is utilized for cooking.

7.1.2. Implications

l The maintenance of improved

stoves is not adequate. The fuel

savings are much lower than the

actual potential of the stoves.

l Majority of households sti l l

cook with less efficient and

smoke-emitting traditional wood

stoves.

l Large amount of fuelwood is

harvested from the forests for

cooking, leading to degradation of

forests.

7.2. Lighting Energy Sources

7.2.1. Current Electrification Status

l About 81% of the households are

electrified.

l In electrified houses, 79% of the

households own other electrical

devices.

l Monthly electricity consumption of

an average household in

Kempanaickenpalayam is 50 kWh.

l Electricity for pumps used for

agriculture is free in Tamil Nadu.

l Almost 97% of the irrigation sources

have been electrified.

7.2.2. Implications

l Reduced drudgery for men and

bullocks.

l Increase in the electrification of

irr igation sources has lead to

reduction in cattle population used

in the animal-drawn water-lifting

devices for irrigation.

7.3. Sanitation

7.3.1. Current Status

l Only 11% of the households have

toilet facility.

l All the toilets are of Indian type.

l About 72% of the toilets have tap

connection.

l There are 2 community toilets in

the vil lage. Due to lack of

maintenance, neither is used by

the villagers.

l Most households (90%) have

cattle sheds separate from the

living area.

Page 31: Kempanaickenapalayam Village Ecosystem

26

l Few households (10%) have cattle

sheds as part of the house.

l About 10% households dispose off

kitchen waste by dumping it in the

streams and by the roadside; the

rest use manure pits or garbage pits.

7.3.2. Factors Contributing

l Lack of awareness about hygiene

and health.

l Lack of water facility in toilets.

7.3.3. Implications

l The fact that 89% of the households

do not have the toilets has serious

implications for hygiene, health and

the quality of life of the people

within the village.

l The economic status of the people

has improved but the quality of life

is far below the desired level.

l Disease incidence among the

community and health hazards are

quite high due to lack of awareness

and initiative.

Page 32: Kempanaickenapalayam Village Ecosystem

8. Overall Trends in Natural Resources

D irect functional relationship exist

between the natural resources in

village ecosystems such as forests, water

bodies, cropland, grazing land and

livestock. A small irrigation dam, which is

now used only for recharge of

groundwater, is a significant element

in the natural resource dynamics

of Kempanaickenpalayam village.

Irrigation and market forces have forced

a shift from traditional and rainfed

agriculture to more water-intensive

agriculture. The dam has been successful

in maintaining the groundwater level so

far but may not support continued

expansion of intensive agriculture in the

future. The dam has also attracted local

wildlife and migratory species of birds

to the village from the surrounding

forests. Life of a significant percentage

of population stil l depends on the

sustainability of forests, water bodies,

cropland and livestock in the village. The

village exhibits significant changes in the

patterns of use of natural resources in the

recent past. Some of the major changes

are mentioned below.

l There has been a notable change in

the land-use pattern of the village

where the cropland has significantly

reduced and fallow land increased

due to changes in the cropping

pattern.

l There is a growing trend of replacing

short-term crops such as paddy and

other cereals with long-term crops

like sugarcane and banana due to

labour shortage and possibility of

higher income.

l The production of food grains is on

the decline while cash crops like

sugarcane are on the increase.

l The population of sheep and goat

has increased significantly over the

last few years.

l The grazing density is very

high due to increase in livestock

population which may lead to

degradation of fallow land and

forests.

l The construction of a dam in

1992 has helped to recharge

groundwater in the village.

l People believe that bird diversity,

specially of the local migratory birds

like cormorants and teals, has

increased after the construction of

the dam.

l The frequency of sighting of large

mammals such as elephant, deer

and wild boar has increased

because of the water availability in

the dam and the cropping pattern

of the village.
