Abstract:
Integrated Rural Development involves policies and
programmes for the development of rural areas with the ultimate
aim of achieving a fuller utilisation of the available physical
and human resources resulting in higher income and better living
conditions for the rural population. It is a matter of concern
to planners in India that there has been a steady decline of the
share of agriculture in GNP. This has been the trend .m
presently industrialized countries as well but unlike them there
has been only a marginal shift in the percentage of population
dependent on agriculture. The result is that those engaged in
the agricultural sector are on the average - less than half as
well off as those in other sectors. It is imperative to think of
a planning approach to evolve a methodology and to demonstrate
that it is possible to increase substantially the agricultural
income by optimal utilisation of land and water resources. This
would result in a stimulus to the entire rural economy as
additional income in the hands of the rural population will
generate demand for industrial goods and other services. To
sustain and accelerate economic growth it would also be necessary
to provide other services and infrastructure out of which the
most important is a road transport network. In view of this fact,
the case study of Bijnor District has been taken up as an
illustration. It is a typical agriculturally oriented district
of Western U.P. with low industrial development. It has a total
land area of 4,84,800 ha with a total population of 24.55 lakhs
according to 1991 census. The present study consists of the
following three parts.
I. Planning to increase agricultural income by optimal use of
land and water resources
II. Estimating the impact of increased agricultural production
on the economy of the district
Demonstration of methodology for planning a Rural Road
Transport Network
A brief description of each of the three follows :
I. Planning to increase agricultural income : This involves
the following steps :
a) Estimation of available water resources - So far irrigation
in Bijnor district has been predominantly based on ground
water. The estimated annual draft comes to 115,673 ham and
the monthly pumping capacity to 53,987 ham. It is assumed
that 85% of this or 45,000 ham/month will be available for
irrigation. A network of Eastern Ganga Canal system is
being extended into the district for supply during Kharif
only. Its present contribution to irrigation is small.
Estimating the ground water recharge from rainfall and
increased seepage from canal system and irrigated fields, it
is worked out that annually 1,66,500 ham will be available
from ground water and 1,16,170 ham from canals, the latter
during kharif only.

b) Selection of crops and estimation of their water
requirements - After studying the existing cropping pattern,
17 crops were selected for planning purposes. The
considerations kept in view were soil and climate, farmer
preference, well distributed demand for water, self
sufficiency in food and fodder and problems of storage and
marketability. For these crops the Field Irrigation
Requirement (FIR) on monthly basis was determined from pan
evaporation data after making due allowance for effective
rainfal1.
c) Estimation of costs and benefits of the selected crops -
Computation of net crop benefits involves estimation of
gross production, its market price and cost of cultivation
including inputs and human labour. The quantities of inputs
like seeds, fertilizers etc. were taken on the basis of
recommended agricultural practices. It was assumed that full
water requirement will be provided to all crops and
irrigation costs were taken according to the availability of
tubewell and canal water. Labour costs were taken on the
basis of available surveys and direct enquiry. The
productivity was taken such as was being obtained in similar
irrigated areas at present.
d) Optimisation of cropping pattern through linear programming
model.
A linear programming model has been adopted to obtain
optimum crop combination for maximum net benefit with
available land and water - that is -
111
Objective Function
Maximise Z = 2 Xi * Bi
where, Xi is the ith crop and Bi is the net benefit for that
crop.
Constraints
The following constraints are obligatory.
1. Total cropped area not to exceed available area in any month.
2 Xi * ai t < At
where ait represents the fraction of month for which the
crop is in the field and At is the total available area for
cultivation.
2. Monthly water requirement not to exceed available pumping
capacity plus canal water input in that month
2 Xi * ALt < Wt
where At t is the monthly water requirement for the ith
crop and Wt is the maximum water availability in that month.
3. Annual ground water withdrawal not to exceed recharge
2 W,t < 1,66,500
Where I Wgt is the ground water pumpage during 12 months of
the year.
4. Non negativity constraint
Xi > 0
Wt > 0
By a process of trial a crop pattern was evolved which
increased the present crop benefits by 80% or a net increase
of Rs. 182.7 crores. This involved no radical departure
from existing farming practices or technology.

II. Estimation of the impact of increased agricultural
production on the Economy of the District.
The additional agricultural production will require
agricultural processing units like Dal (pulses) mills, flour and
rice mills, oil expellers and cold storages etc. Their number
was estimated and it is seen that they will provide regular
employment to 32,400 persons.
The more intensive cropping will result in increased
employment directly in the farm sector of 15 million mandays.
Besides these activities there will be substantial additional
employment through trade and service activities.
Besides the direct impact, there will also be a multiplier
effect due to increased demand for consumer goods and services as
well as social sector services. According to John Glasson the
multiplier effect K is defined as
K
1
1 - (c - m) (1 -t)
Where C = marginal prospensity to consume
C = I - S where S is marginal capacity to save
m = marginal prospensity to import
t = marginal rate of taxation
Taking reasonable values of 20% for S, 30% for m and 5% for
t, k comes to 2.10. With this factor the economic activity
generated will be 2.1 x 182.7 = Rs. 383.609 crores.
III. Demonstration of methodology for planning a rural Road
Transport, Net work - The most important infrastructural ' development for sustained economic growth is an all weather road
network. Najibabad Tehsil in Bijnor district was selected for
planning a most efficient rural road network.
A number of growth centres were initially identified based
on their population and other attributes like education, health,
P & T, market days, communications and power supply etc. The
entire area was then divided into hexagons having a side of 4 km.
25 such hexagons were formed, a few of them partial. A growth
centre was selected for each hexagon. The road network has t
link these growth centres to each other and to the major urban
centre of Najibabad. The demographic force of interaction
between any two centres was calculated by the following
expression.
Pi x Pj x CSi x CSj
Fij = _
d2i j
o
where Pi and PD are the populations, CSi and CSj the centrality
scores and dij the distance between centres iand jrespectively.
A road network has been planned which keeps the total link
length (total road length to be constructed) and the total route
length (the total distance required to be travelled from every
node to all other nodes) at a minimum or optimum level.
CONCLUSIONS
The study revealed that optimal use of resources can result
in a substantial increase in rural incomes. This results in a
very considerable rise in economic activity and employment. A
methodology has been demonstrated to plan a rural road network
for maximum efficiency at minimum cost.
