d land and water resources regions termed as Composite Land Development Units 
(CLDU), and their spatial distribution, potential and limitations for sustained 
agriculture and other uses; and development of an integration key. The first 
Step was accomplished by superimposing individual thematic map over each 
other manually and identifying CLDUs. This could also be done by digitizing/ 
xd scanning all the thematic maps and studying them subsequently in a GIS 
1s environment. Each CLDU was then studied carefully with respect to potentials / 
- limitations of ^ various natural resources and socio-economic and climatic 
d conditions and a specific land use and/soil and water conservation practice are 
n, suggested. Subsequently, taking landform as a base an integration key in terms 
jh of potential/limitations of soils, present land use/land cover, and ground water 
Il | potential; and suggested alternate land use/action plan was developed.

d, | 8.2.3 Implementation of Action Plan 
er 
as The action plan and/alternate land use practices emerging from aforesaid 
y | approach are implemented in part of the watershed by the implementing 
s, agencies in the district depending on availability of funds. The state-of-the-art 
n, | technology available for each action item i.e. activity to develop land and water 
dy resources of an area, is used in order to fully exploit the contemporary research 
el and developments in the field of agriculture, science and technology. While 
n implementing the action plan, the aspiration of the local people obtained through 
/e a process called Participatory Rural Appraisal (PRA) is given utmost importance. 
1e Initially, a micro watershed of 500 — 1,000ha is identified by the district/block 
All authorities based on developmental priority and the operational aspects of each 
re activity under action plan is studied carefully. Since most of the land except for 
id | common  land/government land, belongs to cultivators/individuals, for 
as | implementation of action plan information on each land holding which is available 
e, | in cadastral maps (large scale village maps) is required. For this purpose, 
rk cadastral map boundaries were digitized/scanned and overlaid onto satellite 
| data. The individual field where a specific action plan is recommended could be 
identified by superimposing action plan map over digitized/scanned cadastral 
ur maps. The progress of the implementation is monitored by an expert committee 
ia | constituted by the state government for each state/district.

lic 8.3 IMPACT ASSESSMENT 
al 
Sic After implementation of suggested action plan for land and water resources 
development, the area undergoes transformation which could be monitored 
regularly using satellite data and in situ observations. Such an exercise not only 
helps studying the impact of the programme but also enables resorting to 
midcourse correction, if required. Parameters included under monitoring 
1d | activities are land use/land cover, extent of irrigated area, vegetation density and 
us condition; fluctuation of ground water table, well density and yield, cropping
