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  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  soil 
conservation  schemes  has  been  done  by  the  Directorate  of  Economics  and  Statistics 
for all districts except Wayanad.  This  report  relates  to  the  survey  results  of 
39Schemes  completed  by  the  Soil  Conservation  Department  and  various  other 
agencies.  The field survey was conducted during the agricultural year 2014-15 by the 
Statistical  Investigators  under  the  supervision  of  the  Research  Officer  and  Deputy 
Director  in  the  District  Offices.    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,  Agricultural  Geologists  and  others  interested  in  the 
subject. The efforts taken by the staffs of this section is appreciated. 
  I  acknowledge  my  thanks  to  the  staff  of  Soil  Conservation  Department  and 
other  local  bodies  for  their  valuable  suggestion  and  whole  hearted  co-operation  for 
the successful conduct of the survey in the state.

  Chapter – I 
 
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 
capability  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. 
1.2   Objectives and Methodology  
 
The main objectives of the evaluation study are:  
1. To assess the benefit of the programme particularly in relation to the cultivation 
of 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 this direction 
 
For  this,  schemes  executed  five  years  prior  to  the  survey  i.e.  during  2009-10 
in the State by the Soil ConservationDepartmentLocal Self Government Department 
and other Government agencies were selected.  The study covered all the districts of 
the  State  except Wayanad.  The list  of  beneficiaries  under each scheme is  collected 
from  the  Soil  Conservation  Department,  Local  Self  Government  Department  and 
other  Government  agencies.      The  beneficiaries  are  selected  by  stratified  random 
sampling method on the basis of the area of the holding.  The holdings are stratified 
into four stratums.

  Holdings with less than 1 acre

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  from  the  list  of  beneficiaries  collected  from 
Soil  Conservation  Department,  local  bodies  and  other  Government  agencies.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.  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.   Name  of  all 
selected schemes from all districts except Wayanaddistrict are given in 1.3.

acres.    In  order  to  compare  the  benefits  of  the  implementation  of  Soil  Conservation 
Programmes,  control  plots  were  also  selected.    Its  distribution  is  57.5%,  40.31%, 
1.25% and 0.94% respectively under Stratum I, II, III and IV. 
Following  schedules  were  used  for  collecting  the  details  from  beneficiary  plots 
and control plots.

Schedule II  -  Detailed study of the selected beneficiaries 
Schedule III  -  List of control plots 
Schedule IV  -  Detailed enumeration of the control plots 
 
1.4.Problems of Soil Erosion 
 
Soil  erosion  means  the  disappearance  of  the  topsoil  by  the  action  of  wind  and 
water.  Ultimately soil erosion leads the desertification of land.  Degradation of natural 
resources  has  lead  to  many  indirect  damages,  such  as  increasing  extent  of  wasteland, 
soil  erosion,  land  sliding,  etc.  all  these  cumulatively  or  independently  affected 
agricultural area or reduce 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  5cm  to  10  cm  of  the  top  soil  (ranging  from  0.05m  to  0.1  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  gifts  of  the  nature  embodies  soil,  water  and 
associated  flora  and  fauna  involving  the  total  ecosystem.    The  topography  of  the  land

7 
  plays  the  most  important  role  in  soil  erosion.    Kerala  is  a  narrow  strip  of  land  (width 
varies from   15 Km to 120 Km) situated  on the Western Slopes of the Western Ghats 
(the Sahyadri).  The very steep slopes facilitate quick run off of the rainfall resulting in 
low  time  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 is more prone to erosion.  The different forms of soil erosion cause huge damage 
to Kerala’s economy every year and reported casualties every year due to landslides in 
monsoon season. 
1.5     Methods of Soil Conservation Programme 
 
Soil  Conservation  practices  are  mainly  grouped  into  two  categories  viz. 
Agronomical  and  Engineering  measures.  Agronomic  measures  are  comparatively 
less  costly  such  as  contour  ploughing  /  optimal  fertilizing,  organic  farming,  etc.  
Engineering  measures  include  contour  bunding,  land  levelling,  construction  of 
check  dams  and  water  harvesting  structure,  etc.  At  present  various  watershed 
programmes  are  being  implemented  in  the  state  for  effective  preservation  and 
management of the natural resources. 
1.6   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,  conversion  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  leaves  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,  soil  conservation  programme  was  executed  by  Department 
of  Agriculture/Soil  and  Water  conservation.  Due  to  soil  and  water  conservation 
works  there  was  an  increased  employment  among  rural  people  which  improved 
income  of  people  and  reduced  migration  of  labour.    Soil  and  water  conservation 
structures  in  arable  and  non  arable  lands  reduces  soil  erosion,  soil  loss,  run-off 
water,  etc.  and  increased  rainwater  infiltration,  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,  there  was  a  proposal  from  the  Government  that  people  should 
contribute  5-10%  or  more  towards  soil  and  water  conservation  works.    Farmers 
contributed  in  some  of  the  watersheds  based  on  the  direct  benefits  derived  from 
such activities; 
Soil  can  be  well  maintained  through  bunding  (mechanical  and  mechanical-cum-
vegetative  barriers),  deep  ploughing,  levelling,  smoothening,  etc.    Bunding  was 
accepted  by  farmers  to  strengthen  existing  bunds  without  any  obstruction  in  their 
plot   Moisture conservation on measures increased yield magically. 
Farmers  in  different  parts  reported  the  fact  that  the  sustainability  of  agriculture  is 
only possible by soil and water conservation measures.  They also reported that soil 
erosion 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  Ns.  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 
1685.91  acres  to  1719.07  acres  after  the  implementation  of  soil  conservation 
programme.  An  additional  area  of 33.16 acre  of land  has  brought  under  cultivation 
which was not cultivated earlier.  Hence it can be stated that 1.97% 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 93.14% to 94.97% by decreasing the current fallow from 3.04% to 1.25% . 
          On  examining  the  district  wise  data,  a  marginal  increase  is  noted  in  the  area 
additionally  brought  under  cultivation  in  Idukki,  Malappuram,  Alappuzha, 
Kozhikode, Thiruvananthapuram and  Kannur.

  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; multi-storeyedcropping, etc. are 
also beneficial in controlling soil 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 rainfall.

17 
   
Consequent  in  the  introduction  of  the  soil  conservation  programmes 
significant changes in the cropping pattern occurred which favours perennial crops.  In 
Table  4  the  area  under  perennial  crops  has  increased  from  1403.7  acres  to  1457.38 
acres.    It  showed  an  increase  of  3.82%.    At  the  same  time  the  percentage  change 
occurred  in  the  cultivation  of  seasonal  crops  recorded  as  13.67  %.    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  Banana,  Plantain,  Vegetables,  Colocasia  and 
Tapiocaexhibited  comparative  increase.    The  respective  percentage  changes  recorded 
as 339.01%, 16.32%, 12.2%, 7.4%,and 2.65% respectively.  
  Table No. 5 reveals that after the introduction of soil conservation programmes, 
Rubber  and  Coconut  have  occupied  the  large  area  under  perennial  crops  contains 
883.85  acre  and  304.75  acre  respectively.  The  percentage  increase  ofCardamom 
comesan  increase  of  24.24%.  The  Area  under Arecanut and  Cashewhave  decreased  to 
2.94% and 34.59% after the Soil Conservation Programme. 
  By  analyzing  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 No7 and 8. Survey result 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.
  In Kozhikkode district Gross cropped area is more increased.   In this district total 
cropped  area  before  Soil  conservation  works  was  34.9  acres.    Itis  increased  to  66.81 
acres  after  the  implementation  of  Soil  conservation  measures.    The  increase  in  area  is 
accounted  as  31.91  acres.    The  percentage  of  increase  recorded  as91.43%.    When  we 
analyzethe  yield  of  perennial  crops  in  this  district,  it  can  be  seen  that  production  of 
Coconut,  Pepper,  Arecanut,  are  increased.   In  the  case  of Seasonal  crops,  in  this  district 
it can be seen that the yield of tapioca, plantain, banana etc. are increased. 
  In  Kasargode,  Malappuram,  Idukki  and  Ernakulum  districts  before  soil 
conservation  work,  thetotal  gross  cropped  area  were  249.01,  78.47,  202.93  and 
183.14acres  respectively.    It  is  increased  to272.41,  93.29,  208.80and187.80  acres 
respectively  after  the  implementation  of  soil  conservation  work.  Increase  in  area 
accounted are 22.8, 14.82, 5.87and 4.66 respectively.     
  Production  impact  is  also  commendable.    Productions  of  all  perennial  crops  are 
increased Except Cashew   after soil conservation works. 
The  district  wise  details  ofSeasonal  Crops  area  shows  that  area  of  all  other 
seasonal crops except ginger &pineapple are increased.

  2.2. Cost Benefit Analysis of the Soil Conservation Programmes 
  An important objective of a project evaluation is to estimate 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  continues  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 depletes 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  compared  further  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 benefits are the intangible benefits derived from 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 its 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 39 schemes is ₹127996853/-. 
The  total  area  under  cultivation  after  soil  conservation  work  was  1719.07acres.  
The  value  of  crops  before  the  soil  conservation  programme  comes  to  ₹91373742/-  and 
the  value  of  crops  after  the  implementation  of  soil  conservation  programme  has  also 
been  calculated  as  ₹200427370/-  .    It  is  estimated  that  the  value  at  constant  price  as  ₹ 
161929266/- .

39 
   
 
Several benefits flow from the soil conservation programme implementation,  three of 
them, which derive special attention are taken up for consideration.   
They are: 
(i)  Extension of area under cultivation 
(ii)   Increase in productivity 
(iii)  Diversification of cropping pattern 
 
(i) Extension of area under cultivation 
   
  The  study  revealed  that  33.16  acres  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  soil 
conservation programme. 
 
(ii) Increase in Production 
 
Production also increased due to the implementation of soil conservation programme.  
In  the  case  of  coconut,  it  recorded  28.31%,  Pepper  20.56%,  Rubber  19.02%,  Jack 
36.19  %,  Mango  376.7%,  Cardamom158.56%,  Cocoa  40.79%  and  Nutmeg  56.38%.   
In  the  case  of  seasonal  crops,  percentage  increase  in  production  of  Paddy,Tapioca 
,Ginger,  Plantain,  Banana  ,Elephant  Yam,  Colocasia  and  Vegetables  are    30.84%, 
9.8%, 11.58%,   24.74%,12.33%,34.09%,21.81%and28.38% respectively.  
 
(iii) Diversification of cropping pattern 
 
  Soil  Conservation  Programmes  increased  the  soil  capacity  and  which  facilitates 
the  cultivation  of  more  remunerative  crops.    This  advantagecanbe  reaped  in  full,  only  if 
the  conservation  programmes  are  followed  properly,  i.e.  the  dissemination  of  new 
techniques  of  production,  adequate  provision  of  inputs  and  service  which  will  promote 
the land to improve production.

40 
    In  the  scheme  area,  cultivation  of  perennial  crops  has  shown  encouraging 
performance.  The increase in area of perennial crops is higher than the area under same 
before  the  conservation  programme  (3.82  %.)    Growing  of  perennial  crops  will 
accelerate conservation of soil more affectively. 
 
Occupational Profile 
 
  The  occupational  profile  of  the  selected  beneficiaries  reveals  that  40.99% 
included  agriculture  job,  41.11%  are  accounted  as  non-agriculture;  9.74%  agricultural 
labourersand8.16%  are  categorized  as  non-agricultural  labourers.    Details  are  presented 
in Table No. 14 and 14 (a).

During  the  survey  period  the  staffs  of  this  department  has  visited  all  the 
beneficiary plots. 
The  distribution  of  holdings  of  the  selected  beneficiaries  of  the  soil conservation 
programmes  reveals  that  56.55%  of  the  beneficiary  holding  belongs  to    less  than  one 
acre, 38.46% have holding area between one acre to 3 acres,   above 3 acres were 4.17%  
and  up to 5 acres were 0.82% respectively. 
The  opinions  of  selected  beneficiaries  are  collected.    Out  of  this,  32.32%  of  the 
beneficiaries  reported  that  contour  bunds  effectively  controlled  soil  erosion  while  about 
67.24% rests in the opinion that it moderately controlled soil erosion.  
About  the  fertility  of  the  soil  11.70%  are  of  the  view  that  the  conservation 
measures  have  improved  the  fertility  of  the  soil  remarkably  while  87.54%  reported  that 
the  fertility  of  the  soil  has  improved  moderately  and  0.76%  opinioned  that  it  has  no 
effect on the fertility of the soil. 
Similarly  regarding  the  moisture  retention  9.74%  reported  that  the  scheme  has 
substantially  controlled  moisture  retention  while  89.69%  reported  that  the  scheme  has 
caused  moisture  retention  moderately  and  0.57%  reported  that    no  effect.  Details  are 
presented in Table No. 12

  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  with 
minimum disturbance to the environment.  Through this water and soil can be conserved 
since  both  of  them  are  interdependent.    The  overall  objective  of  watershed  programme 
includes  recognition  of  watershed  as  a  basic  unit  for  judicious  utilization  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  71.28%  are  in 
good  condition  27.77%  reported  that  bundsare  partially  damaged  and  0.95%  reported 
that bunds are  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 2014-15.  The entire districts except 
Wayanad  were  covered  in  this  study.    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  in  this  report  district  wise  name  of  all  selected  schemes  are  also 
included.  Some of the findings of the study are given below: 
 For  the  study  purpose  39  schemes  were  selected.    The  total  number  of 
beneficiaries  comes  to 8243. Out of  this  1581  number  of  beneficiaries  were selected for 
the  detailed  study.      Land  use  particulars  of  beneficiary  plots  give  us  certain  positive 
trends while  comparing  with  the area before  and after  the soil  conservation  programme.  
The  study  revealed  that  33.16  acres  of  land  has  been  additionally  brought  under 
cultivation by cultivating area which was 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.    BesidesSoilConservationDepartment,LocalSelfGovernment  implementing 
various  programmes  in  this  direction.    WGDP,  RIDF,  TSP  programmes  are  included 
under study.  Tribal colonies also enjoyed benefits.

51 
  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  133.53%.    It  is  estimated  that  the  percentage  increase  of  net 
income per acre in beneficiary plots of the scheme area as 129.03%.  Analysis  of  data  collected  from  the  beneficiary  and  control  plots  reveals  that  the  net 
income  per  acre,  received  from  the  beneficiary  plot  is  ₹.78481/-  and  from  the  control  plot  is 
₹.59281/-   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.  Cost  benefit  analysis  of  the  collected  data  reveals  that  85%  of  the  cost  of  soil 
conservation programme has benefited in the year under study.   Table 15
