PREFACE 
 
 
 	
  One of the most valuable gifts of nature to mankind is soil .For the maintenance of soil, 
adequate protection and conservation is necessary. Due to the peculiarity of the rainfall and 
topography of the state, soil conservation assumes importance in our planning process. Heavy soil 
erosion results in the loss of fertility and moisture content of the earth’s surface and diminishing rate 
of agricultural production. Hence Government is implementing various soil conservation measures 
through the soil conservation department, local bodies etc ,for maintaining the fertility and moisture 
content of the surface soil. 
  The Evaluation study of these schemes has been done by the Directorate of Economics and Statistics 
for all districts except Wayanad where the direct implementation and evaluation of the schemes are 
done by the Central Agency.   
  This report relates to the survey results of 51 schemes completed by the Soil Conservation 
Department and various agencies.  The field survey was conducted during the agricultural year 2011-
12.  The schemes implemented and completed before five years are taken up for study so that full 
benefit of the scheme could be evaluated and assessed.  This evaluation study results may be much of 
use to Administrators, Statisticians, Research Scholars and Agricultural Geologists and others  
interested in the subject. 
  The tabulation was done in the Evaluation Division of this Directorate.  The Report of the 
survey has been prepared by Sri. Suresh Kumar N, Deputy Director , Sri. Gopa kumar R, Research 
Officer, Smt. Nazeema Begum.Z, Research Assistant , Smt. Minimol S, Statistical Assistant Gr I , Smt 
Gracy K K ,Statistical Assistant GrI, and Smt.Sreekala.U Statistical Assistant Gr I, under the guidance 
of Smt. K. Sathiabhama, Additional Director.  In this context I acknowledge my thanks to the staff of 
Soil Conservation Department and other local bodies for their valuable suggestion and whole hearted 
co-operation in the successful conduct of the survey.

1.1 Introduction  	
 
 
Land is one of the basic resources of a nation.  Productive land is the source of human 
sustenance and security.  The future of the country and its teeming millions depend to a large 
extent, the conservation of its fertile soil through the proper land use and scientific 
agricultural practices. 	
 
  Soil conservation means applying of all necessary practices to maintain the capabilit y 
of land for which it is suited and to improve the productivity of agricultural land.  Considering 
the importance of soil conservation our plan provisions enhanced for optimizing the use of 
land resources.  An evaluation study in this front can be helpful for developing much more 
suitable conservation measures for the State 
 
1.2 Objectives and Methodology of the Survey:- 
 
The main objectives of the evaluation study are:  	
 
1. To assess the benefit o f the programme part icularly in relat ion to the cult ivat ion o f 
seasonal and perennial crops. 
2. To throw light on various aspects like cost benefit analysis, production potential etc 
3. To estimate the extent of additional area brought under cultivation consequent on the 
implementation of the programme. 
4. To study the effects of the work carried out by the Soil Conservation Department in 
t his d ire ct io n 
 
For this schemes were selected which were executed five years before ie during   
2006-07 in the State by the Soil Conservation Department and other local bodies.  The study 
covered all the districts of the State except Wayanad where the same is directly done by the 
Central Government.  The list of beneficiaries under each scheme is obtained fro m the So il 
Conservation Department and other local bodies. The beneficiaries are selected by stratified 
random sampling method on the basis of the area of the holding.  The holdings are stratified 
in to four viz. 
Holdings with less than 1 acre  - Stratum I 
Holdings with 1 acre or more but less than 3 acres  - Stratum II 
Holdings with 3 acre or more but less than 5 acres  - Stratum III 
Holdings with 5 acres and above  - Stratum IV

Selection of Beneficiaries  
 
  Selection of beneficiaries is done by the District Level Officers from the list of 
beneficiaries collected from Soil Conservation Department and from other local bodies.  A 
total number of 25 beneficiaries are selected from each scheme by simple random sampling 
covering all the above 4 stratum with at least 6 from each stratum.  If in any stratum, the total 
number of beneficiaries in the frame is less than the number to be selected the shortfall is 
compensated from another stratum with the nearest area of the holding.  If the beneficiaries in 
a scheme are less than 25, all of them are selected.  For the purpose of comparison 5 control 
plots are also selected from the scheme area, where the soil conservation works are not carried 
out under any scheme.  The district wise select ion details o f beneficiary plots and control 
plots are given in the table 1 & 1 (a).

The total number of beneficiaries comes to 1500  About 58.87% of the beneficiaries are 
having holding less than one acre, 31% are having holdings one acre or more but less than 3 
acres, 6.6% are having holding 3 acre or more but less than 5 acres and only 3.53% of the 
beneficiaries are having holdings of more than 5 acres.  In order to compare the benefits of the 
implementation of Soil Conservation Programmes, control plots were also selected.  Its 
distribution is 64.91%, 24.9%, 7.55% and 2.64

1.3 Problems of Soil Erosion 
  
Soil erosion means the disappearance of the topsoil by the action of wind and water.  
Ult imately so il erosion leads the desert ification of land.  Degradat ion o f natural resources has 
led to many indirect damages, such as increasing extent of wasteland, soil erosion, land 
sliding, etc. all these cumulatively or independently has affected agricultural or independently 
has affected agricultural productivity.  Unlike other parts of the country, Kerala has some 
unique land form related aspects such as over 90% of the geographical area is either in 
midland or high land category.  The average rate of soil erosion in the country, to the tune of 
16.3 t/ha/yr – has been alarming and has to be checked.  In hilly areas, the rate is much higher, 
i.e. about 30 to 50 t/ha/yr/, considering that about 5 to 10 cm of the top soil (ranging from 0.3 
to 1.0 m depth) is being lost every year due to lead management practices.  It has been 
estimated 9-5 lakh hectares of cultivated land in the State is having soil erosion problems. 
 
 
Responsibility for prevention of erosion    
 
  Land which is one of the precious gift of the nature embodies soil, water and 
associated flora and fauna involving the total ecosystem.  The topography of the land plays 
the most important role in so il erosion.  Kerala is a narrow strip of land (width varies from 15 
to 120 Km) situated on the Western Slopes of the Western Ghats ( the Sahyadri).  The very 
steep slopes facilitate quick run o ff o f the rainfall result ing in low t ime of concentration poor 
ground water recharge.  This high velocity of the surface flow causes soil displacement and 
movement.  The surface soil gets washed away along with the running water.    The major 
portion of the state is laterite and as such are more prone are erosion.  The different forms of 
soil erosion causes huge damage to Kerala’s economy every year.  Many people die every 
year due to land slides.

1.4 Methods of Soil Conservation Programme 
 
Soil Conservation practices are mainly grouped into two categories viz.  Agronomical 
and Engineering measures. Agronomic measures are comparatively low costly such as 
contour ploughing / optimal fertilizing organic farming, etc.  Engineering measures include 
contour bunding, land leveling, construction of check dams and water harvest ing structure, 
etc. At present various watershed programmes are being implemented in the state for effective 
preservation and management of the natural resources. 
 
1.5 Land Use Particulars of the State 
 
 There has been a significant change in the land use of the state over the years.  On 
many occasions the change is adversely affecting the environment by way of intensified soil 
erosion, water logging, convertion of paddy lands, etc. are some of the examples.  Cultivation 
of very steep lands without adopting scientific conservation practices lead to heavy soil 
erosion.  Use of chemicals on a large scale for agricultural productions leave dangerous 
quantities of the residues in the soil and the water sources.

Chapter -  II 
2.1  Impact of Soil Conservation Programme on Land use and Crop Pattern   
 
    Before 1994-95, soil conservation programme was executed by 
Department of Agriculture/Soil and Water conservation, etc.  There was increased 
employment to rural people due to soil and water conservation works and this improved 
income of people and reduced migration of labour from these places to outside.  Soil and 
water conservation structures in arable and non arable lands reduced soil erosion, soil loss, 
run-off water, etc. and increased rainwater infiltration, ground water table, surface storage, 
cropping intensity, productivity of crops, etc.  As long as works were carried out based on 
funding by Government and subsides provided for supporting income generating enterprises, 
there was positive impact. 
After 1994-95, there was a proposal from the Government that people should 
contribute 5-10% or more  towards soil and water conservation works.  Farmers contributed 
in so me of the watersheds based on the direct benefits derived fro m such act ivit ies; 
Soil can be well maintained through bunding  (mechanical and mechanical-cum-
vegetative barriers), deep ploughing, leveling, smoothening, etc.  Bunding was accepted by 
farmers to strengthen exist ing bunds wit hout any obstruction in their plot   Moisture 
conservation on measures increased yield magically. 
Farmers in different parts reported that the fact that the sustainability of agriculture is 
only possible by so il and water conservat ion measures.  They also reported that soil erosio n 
can be minimized and irrigation potentials can be improved through soil and water 
conservation measures.  In addition, vegetation covering the soil is a must for minimizing soil 
loss even further. 
Land Use particulars of Beneficiary plots 
  Table Nos. 3 and 3(a) reveals the land use particulars of beneficiary plots and control 
plots respectively.  It gives us certain positive trends while comparing with the area before 
and after soil conservation programme.  Area increased from. 1664.19 acres to 1698.85 acre 
after the implementation of soil conservation programme.  An additional area of 34.66 acre of

Evaluation Study on Soil Conservation 2011-12 	
Department of Economics & Statistics, Kerala 	7	
land has brought under cultivation which was not cultivated earlier.  Hence it can be stated 
that 2.08% of area over the area cultivated before soil conservation programme is due to the 
implementation of soil conservation measures.  In other words area under cultivation has 
increased from 88.75% to 90.60% by decreasing the current fallow. 
          On examining the district wise data a marginal  increase is noted in the area additionally 
brought under cultivation in Malappuram, Kasaragod,Kottayam, ,. 
      In   control plots also the land use is more or less same as in the area of beneficiary plots, 
before soil conservation programme.  Hence it is suited for a comparison with the beneficiar y 
plots.  
In Kannur district the list of schemes was not available for the survey.

Crop Pattern 
 
  In order to reduce  the soil loss an appropriate cropping pattern is essential.  The 
selection of suitable vegetation that form good canopy can reduce erosion since soil loss is 
governed by the extent of exposed land surface.  The binding force of the roots also offers 
good resistance to erosion.  Grass roots have excellent soil binding property.  Legumes are 
also good soil binders.  The grasses, legumes and tree crops are classified as erosion 
preventing or soil conserving crops while cereals, tapioca, ginger, etc. are erosion 
permitting/erosion favouring crops. 
  
Depending upon the capability class to which a land belongs and the socio-economic 
needs of the people, the appropriate crops can be selected to achieve maximum conservation 
of soil and water. 
 
Contour Farming 
  
Contour farming refers to village practices of applying all treatments along contour; 
i.e. across the direction of the slope.  The crops are cultivated along contour ridges and 
furrows.  In regions of low rainfall contour farming helps in the conservation of rainwater and 
in human areas it reduces soil loss and increases recharge of aquifers.  This practice can 
minimize the effects of flash floods and droughts. 
  
Mixed farming, intercropping, mixed cropping; multistoried cropping, etc. are also 
beneficial in controlling so il erosion. 
  
The growing of perennial horticultural crops, including plantation crops will give a 
permanent protective cover for the soil. In high rainfall areas of the humid tropics this higher 
level tree cover for the soil helps in reducing the erosive action of highly intensive rainfa ll. 
  
Consequent in the introduction of the so il conservat ion programmes significant  
changes in the cropping pattern occurred which favours perennial crops.  The area under 
perennial crops has increased from 1378.31 acre to 1465.50 acre.  It showed an increase of

Evaluation Study on Soil Conservation 2012-13 	
Department of Economics & Statistics, Kerala 	13	
6.32%.  At the same time the percentage change occurred in the cultivation of seasonal crops 
recorded as 14.20 %.  From this we can arrive at the conclusion that the farmers have shown a 
tendency to cultivate perennial crops in sloppy regions where the soil conservation measures 
are carried out.  The cultivation of seasonal crops in such regions is likely to increase soil 
erosion.  In seasonal crops the cultivation of Plantain,Tapioca, Banana are exhibited increases.  
The respective percentage changes recorded as 31.44%.12.51%,6.61%   
  
Table No. 5 reveals that after the introduction of soil conservation programmes, 
Rubber has occupied the largest area under perennial crops; the percentage increase is 10.7 %.  
coconut comes next with an increase of  1.95%. The area under Arecanut has decreased to 
15.92% after the Soil Conservation Programme. 
  
On going through the district wise data, it is noted that the cropping area under 
different crops are interchanged according to the suitability of land.

Impact of Soil Conservation Treatment on the Yield of Crops 
 For studying the impact of soil conservation treatment on the yield of crops a detailed 
survey was conducted following the “Before” and “After” method.  Details regarding the 
yield and value of crops are collected from the beneficiaries in the scheme area.  District wise 
details are presented in table No. 7 and 8 Survey results reveals that in most cases, the crop 
yields after the implementation of the programme were higher than that of before.  Therefore 
the total output from crops represented a big increase.  As much as major portion of this 
output came from perennial crops indicating improved stability in output.  Almost all 
perennial crops have also shown a marked improvement. 
  For example in Malappuram district total cropped area before soil conservation works 
was 142.18 acres.  It increases to 166.46 acres after the implementation of  soil conservation 
measures.  The increase in area is accounted as 24.28 acres.  The percentage increase recorded 
as 17.08  When we analyse the yield of perennial crops in this district it can be seen that 
production of Coconut,Rubber Cocco,Cardamom Nutmug,etc. increased.  . 
  In Idukki,Kasaragod,Kollam, and Thiruvananthapuram districts before soil 
conservation work the area were 139.67 acres, 173.32 acres, 13.62 acres and 38.48 acres 
respectively.  It increased 163.83, 188.73, 21.88, 44.38 acres after the implementation of soil 
conservation work.  Increase in area accounted as 24.28, 15.41, 8.26, 5.90 acres respectivily.   
 . 
  Production impact is also commendable.  Output of all perennial crops increased after 
soil conservation works. 
The production details of seasonal crops of these districts shows that plaintain area and 
production increased and in the case of  banana, vegitables and tapioca also the  area and 
production increased.

2.2. Cost Benefit Analysis of the Soil Conservation Programmes 
 An important objective of a project evaluation is to estimate the various impacts of its 
operation such as income, employment, demographic change, regional development and so 
on.  Hence an analysis to appraise the performance of operating investment projects is 
essential for improved planning process.  Degradation of land due to soil erosion leads to 
destruction of agricultural land.  If it continue over a period, the entire soil will be lost and the 
land will become barren and unproductive.  In the case of sloppy regions, soil erosion deplete 
the fertility of the soil and production and degradation of the area under agriculture is to be 
assessed in terms of production and protection benefits accrued from these areas.  These 
benefits are to be further compared with the investments to arrive at benefit cost ratio which 
gives an indication of viability of the programme implemented. 
Productive benefits are the direct returns from the programmes implemented.  In 
regular agricultural lands, increase in the yield provides the productive benefits.  In addition., 
production  from degraded land, which are cultivated after the soil conservation measures are 
also taken into consideration.  
Protective benefit s are the intangible benefits derived fro m implementation of soil 
conservation programme.  These benefits are more stable and provide base for the continued 
prosperity in the area.  In the case of agricultural land, protective benefits are assessed in 
terms of these increased values because of the prevention of further soil erosion and it’s 
increased productive potentialities. 
In the light of the present study an attempt is made for cost benefit analysis with the 
collected data.  Total cost incurred for the soil conservation works, including maintenance 
work  for the 51schemes is Rs.69002113/- 
The total area under cultivation after soil conservation work was 1698.85 acres.  The 
value of crops before the soil conservation programme comes to Rs.73706808  The value of 
crops after the implementation of soil conservation programme has also been calculated as Rs. 
211439544/-  Thus the additional benefits due to the implementation of soil conservation 
programme is worked out to be Rs.137732736  /-.  It is estimated that the value at constant 
price as Rs. 183295567/- .

Several benefits flo w fro m the so il conservat ion programme implementation.  Three o f 
them, which derive special attention, are taken up for consideration.   
 
 
They are: 
  
(i) Extension of area under cultivation 
(ii) Increase in productivity 
(iii) Diversificat ion of cropping pattern 
 
(i) Extension of area under cultivation 
  
  The study revealed that 34.66 acre of land has been additionally brought under 
cultivation by cultivating areas which were not cultivated before soil conservation 
programme.  This benefit is achieved only due to the implementation of so il conservat ion 
programme. 
 
(ii) Increase in Productivity 
 
Productivity also increased due to the implementation of soil conservation programme.  In  the case of 
coconut it is recorded 20.93%, cardamom 258.33%, Rubber 14.60%, Plantain 31.44%..  	
 
(iii) Diversification of cropping pattern 
 
 Soil Conservation Programmes increase the soil capacity and which facilitates the 
cultivation  of more remunerative crops.  This advantage can be reaped in full, only if the 
conservation programmes are followed properly, i.e. the dissimination of new techniques of 
production, adequate provision of inputs and service which will promote the land to improve 
production. 
 
 	In the scheme area, cultivation of perennial crops have shown encouraging 
performance.  The increase in area of perennial crops is higher over the area under same 
before soil conservation programme (6.78%).  Growing of perennial crops will accelerate 
conservation of soil more affectively.

percent opinioned that it moderately controls soil erosion.  The rest 8.66% are of opinion that 
it has no effect. 
  
About the fertility of the soil 11.93% are of the view that the conservation measures 
have improved  the fertility of the soil  remarkably.  While 87.27% reported that the fertilit y 
of the soil has improved moderately and 0.8% opinioned that it has no effect on the fertility of 
the soil. 
  
Similarly regarding the moisture retention 10.6% reported that the scheme has 
substantially increased moisture retention while 88.67% reported that the scheme has caused 
moisture retention moderately only.  0.73% are of no effect. Details are presented in table No.

  One important finding of this study is that the concept of watershed management has 
been well recognized in the scheme area. Watershed management implies the wise use of  
soil, water and bio-resources in a watershed to obtain optimum production wit h minimu m 
disturbance to the environment.  Through this water and soil can be conserved.  Since both of 
them are interdependent.  The overall objective of watershed programme include, recognition 
of watershed as a basic unit for judicious ut ilizat ion and development of all lands.  The land is 
to be treated according to the capability and requirement by adopting suitable methods that 
will control soil erosion, conserve water, improve farm income control flood and droughts, 
etc. 
  
There are a number of direct and indirect outcome of the project  that can be 
associated  with the impact of watershed development project.  These include raising rain fed 
agricultural productivity changes in land use pattern, etc.

Conditions of Bund 
 
  While examining the condition of bund the study revealed that 82.87% are in 
good condition 16.6% are partially damaged and 0.53% is seriously damaged.  District wise 
statement is given in Table No. 13. 
 
Summary of Findings 
 
  The data furnished in this report are collected through the Evaluation study on 
soil conservation programmes conducted during 2011-12.  All the district except Wayanad 
were covered in this study.  In Wayanad the study is directly done by the Central Government.  
The methodology of this study was stratified sampling method on the basis of the area of the 
holding.  For the study purpose schemes implemented by the Soil Conservation Department 
and other Local \Self Government were included.  For the purpose of comparison control plots 
are also selected from the scheme area where the soil conservation works are not carried out 
under any scheme.   In the light of the present study an attempt is made for the cost benefit 
analysis with the collected data.  Several benefits flow from the soil conservation programme 
implementation.  Some of the findings of the study are given below: 
  For the study purpose 51 schemes were selected.  The total number of 
beneficiaries comes to 2471.  Out of this 1500 number of beneficiaries were selected for the 
detailed study.   Land use particulars of beneficiary plots gives us certain positive trends while 
comparing with the area before and after the soil conservation  programme.  The study 
revealed that 34.66 acre of land has been additionally brought under cultivation by cultivating 
area which are under the fallow land. 
There is an increasing awareness of the importance of the soil conservation 
programme especially watershed management programme among the people in the scheme 
area.  Besides Soil Conservation Department, Local Self Government also activated various 
programmes in this direct ions.  WGDP, RIDF, TSP programmes are included under study.  
Tribal colonies also enjoyed benefits. 
Income and Expenditure 
 
  The particulars relating to income and expenditure of beneficiary plots reveals 
that after implementation of SC programme net income of the beneficiaries of the scheme area 
increased to 260.35%.  It is estimated that the percentage increase of net income per acre in 
beneficiary plots of the scheme area as 252.99%

Department of Economics & Statistics, Kerala 	41	
  Analysis of data collected from the beneficiary and control plots reveals that 
the net income per acre, received from the beneficiary plot is Rs.87471/- and from the control 
plot is Rs47291/-  The district wise details are presented in Table No. 11 and 11 (a).  The 
higher rate of income from the scheme area is due to the positive impact of soil conservation 
programme. 	
 	
While analysing the production details of various crops it is revealed that an increase 
10.71% recorded in the case of Rubber. Production of coconut also increased 1.95%.  
Whereas the increase of area was 8.1 acers.  Likewise in coffee production area increase is 
recorded as 2.65 acers.,  the area of cardamom increases 11.67 acers. 
 
Cost benefit analysis of the collected data reveals that 199% of the cost of soil 
conservation programme has benefited in the year under study itself.
