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  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  36  schemes  completed  by  the  Soil  Conservation  Department  and  various  other 
agencies.    The  field  survey  was  conducted  during  the  agricultural  year      2013-14  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. 
  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.

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  necessar y  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  stud y  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 were selected which were executed five  years prior to the survey i.e. 
during    2008-09  in  the  State  by  the  Soil  Conservation  Department  ,Local  Self  Government 
Department  as  other  Government  agencies.    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 as other Government agencies.   
The  beneficiaries  are  selected  b y  stratified  random  sampling  method  on  the  basis  of  the  area 
of the holding.  The holdings are stratified into four stratum. 
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  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.  The district wise selection details of beneficiar y plots and control plots are given 
in the table 1 & 1 (a).

The  total  number of beneficiaries  comes  to  1595.    About  59.31%  of  the  beneficiaries 
are  having  holding  less  than  one  acre,  36.74%  are  having  holdings  one  acre  or  more  but  less 
than 3 acres,2.26% are having holding 3 acre or more but less than 5 acres and only 1.69% 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  50.77%,  40.31%,  5.23%  and  3.69%  respectively  under  Stratum  I,  II,  III

1.1 	Problems of Soil Erosion 
   
Soil  erosion  means  the  disappearance  of  the  topsoil  b y  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 16.3t/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  ever y  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  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 
ver y 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  ever y  year  and  reported  casualities      every 
year due to landslides in monsoon season.

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  less  costly  such  as 
contour  ploughing  /  optimal  fertilizing,  organic  farming,  etc.    Engineering  measures  include 
contour  bunding,  land  leveling,  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. 
 
 
1.5   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  b y  way  of  intensified  soil 
erosion, water logging, conversion of padd y 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  1994-95,  soil  conservation  programme  was  executed  by 
Department  of  Agriculture/Soil  and  Water  conservation,  etc.    There  was  increased 
emplo yment  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  b y  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 
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,  leveling,  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 that  the  fact that the sustainability of  agriculture  is 
only  possible  b y  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. 
Table 2 gives number of beneficiaries selected in each district and cost of the  selected 
schemes. Also gives total area covered under the schemes in each district. In 2013-14 year 36 
schemes were selected from 13 districts.

Land Use particulars of Beneficiary plots 
  Table  Ns.  3  and  3(a)  reveals  the  land  use  particulars  of  beneficiar y  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. 1490.73 acres to 1507.55 acres 
after the  implementation of soil conservation programme.  An additional area of 16.82 acre of 
land  has  brought  under  cultivation  which  was  not  cultivated  earlier.    Hence  it  can  be  stated 
that  1.13% 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 90.70% to 91.72% by decreasing the current fallow from 	
4.22% to 3.11%.	 
          On examining the district wise data, a marginal increase is noted in the area additionally 
brought  under  cultivation  in  Alappuzha,  Malappuram  ,Thiruvananthapuram,  Idukki  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  b y  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 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. 
    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  1230.94  acres  to  1273.25  acres.    It  showed  an

Evaluation Study on Soil Conservation 2013-14 	
Department of Economics & Statistics, Kerala 	13 	
increase  of  3.44%.    At  the  same  time  the  percentage  change  occurred  in  the  cultivation  of 
seasonal  crops  recorded  as  63.96  %.    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, Tapioca 
and  Ginger  exhibited  comparative  increase.    The  respective  percentage  changes  recorded  as 
189.90%, 68.54%, 56.99%, 53.52% 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 592.80 acre 
and 483.76 acre respectively. The percentage increase of Cocoa comes an increase of 25.78%. 
The  Variation  of  area  under  Arecanut  and  Cashew  have  decreased  to  41.97%  and  23.49% 
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.               
  In  Malappuram district Gross cropped area  is  more  increased.      In  this  district  ,total 
cropped  area  before  Soil  conservation  works  was  121.05acres.    It  increased  to  139.61  acres 
after  the  implementation  of  Soilconservation  measures.    The  increase  in  area  is  accounted  as 
18.56 acres.  The  percentage  of increase  recorded as 15.33%.  When we  analyze the    yield of 
perennial  crops  in  Kasaragod    district,  it  can  be  seen  that  production  of  Rubber,  Pepper, 
Arecanut,  Cashew  and  Coconut  are  increased.    In  the  case  of  Seasonal  crops,  in 
Thiruvananthapuram  district  it  can  be  seen  that  the  yield  of  tapioca,  plantain,  colocasia, 
banana etc. are increased. 
    In  Malappuram,Thrissur,Kozhikkode  and  Kasaragod  districts,  before  soil 
conservation  work  the  area  were  121.05,103.91,132.07and172.58  acres  respectively.    It  is 
increased  to  139.61,112.19,139.27and179.07acres  respectively  after  the  implementation  of 
soil  conservation  work.    Increase  in  area  accounted  as18.56,8.28,7.20and6.49acres 
respectively.     
  Production  impact  is  also  commendable.    Production  of  all  perennial  crops  are 
increased after soil conservation works. 
The  area  details  of  seasonal  crops  of  all  districts  shows  that  Plantain  area  increased  
after  soil  conservationworks  except  Kollam  and  in  the  case  of  tapioca  the  area  as  well  as 
production increased except Malappuram districts.

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  stud y  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 36 schemes is Rs.107364760 
The  total area  under cultivation  after  soil  conservation work was 1507.55 	
 acres.   The 
value  of  crops  before  the  soil  conservation  programme  comes  to  Rs.64108758    The  value  of 
crops  after  the  implementation  of  soil  conservation  programme  has  also  been  calculated  as  
Rs. 128492067/-    It is estimated that the value at constant price as Rs104410812/- .

Evaluation Study on Soil Conservation 2013-14 	
Department of Economics & Statistics, Kerala 	31 	
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  16.82  acres  of  land  has  been  additionally  brought  under 
cultivation  b y  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 is recorded 32.20%, Pepper 67.56%, Rubber 19.27%, Jack 34.07 % 
Mango  14.87%,  Coffee  55.63%,  Cocoa  57.07%.    In  the  case  of  seasonal  crops,  percentage 
increase  in  production  of  Tapioca,  Ginger,  Plantain  Banana  and  Turmeric  are    74.74,  73.44, 
72.03, 257.50 and140.74 respectively. 
 
(iii) Diversification of cropping pattern 
 
  Soil  Conservation  Programmes  increase d  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  dissemination  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  has  shown  encouraging 
performance.    The  increase  in  area  of  perennial  crops  is  higher  over  the  area  under  same 
before  soil  conservation  programme  (3.44%).    Growing  of  perennial  crops  will  accelerate 
conservation of soil more affectively.	
 	
Occupational Profile 
 
  The  occupational  profile  of  the  selected  beneficiaries  reveals  that  38.06%  included 
agriculture  job, 40. 00%  are  accounted  as  non-agriculture;  11.35	
%  agricultural  labourers  and

3.1 General Observations 	
 
    During  the  survey  period  the  staff  of  this  department  has  visited  all  the  beneficiar y 
plots.   
   
The  distribution  of  holdings  of  the  selected  beneficiaries  of  the  soil  conservation 
programmes  reveals  that  59.31%  of  the  beneficiary  holding  belongs  to    less  than  one  acre, 
36.74% have  holding area between one acre to 3 acres.   And above 3 acre were 2.26%, up to 
5 acres were 1.69% respectively.  
   
The  opinion  of  selected  beneficiaries  is  collected.    Out  of  this,  25.52%  of  the 
beneficiaries  reported  that  contour  bunds  effectively  controlled  soil  erosion  while  about 
74.48% rests in the opinion that it moderately controlled soil erosion.   
    About  the  fertility  of  the  soil  13.35%  are  of  the  view  that  the  conservation  measures 
have  improved  the  fertility  of  the  soil  remarkably  while  86.46%  reported  that  the  fertility  o f 
the  soil  has  improved moderately and 0.19% opinioned that  it  has  no effect on the  fertility of 
the soil. 
    Similarly  regarding  the  moisture  retention  11.60%  reported  that  the  scheme  has 
substantially controlled moisture  retention while  88.21% reported that  the  scheme  has caused 
moisture  retention moderately only.  0.19% are  no effect.  Details are  presented in         Table

  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  78.62%  are  in 
good condition 21.13% are partially damaged and 0.25% 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  2013-14.    The  entire  districts  except 
Wayanad  were  covered  in  this  stud y.    In  Wayanad  the  study  is  directly  done  b y  the  Central 
Government.    The  methodology  of  this  study  was  stratified  sampling  method on  the  basis  o f 
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  stud y,  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  36  schemes  were  selected.    The  total  number  of 
beneficiaries  comes  to 2257.    Out of  this  1595  number of  beneficiaries  were  selected  for  the 
detailed study.   Land use particulars of beneficiary p lots give us certain positive trends while 
comparing  with  the  area  before  and  after  the  soil  conservation  programme.    The  stud y 
revealed  that  16.82  acres  of  land  has  been  additionally  brought  under  cultivation  b y 
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.    Besides  Soil  Conservation  Department,  Local  Self  Government  implementing  various 
programmes  in  this  direction.    WGDP,  RIDF,  TSP  programmes  are  included  under  study.  
Tribal colonies also enjo yed 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  98.32%.    It  is  estimated  that  the  percentage  increase  of  net  income  per  acre  in 
beneficiar y plots of the scheme area as 96.10%

Analysis  of  data  collected  from  the  beneficiary  and  control  plots  reveals  that  the  net 
income  per acre, received from  the  beneficiary plot is Rs.56072/- and from the  control plot is 
Rs.30151/-      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  100%  of  the  cost  of  soil 
conservation programme has benefited in the year under study.
