The primary objective of IWMP is to address the issue of soil degradation & moisture conservation in the rain-fed areas of the state.
The satellite soil moisture can help in the assessment of the impact of the watershed management programme on agriculture. The availability of long term (before and after the project is executed) soil moisture data can help in evaluating the impact of a water resources project. The long-term monitoring minimizes the influence on extreme events on the assessment. Comparison of projects can be done to identify the management practices being more effective.
Estimates of evapotranspiration can be used to quantify crop water productivity—the amount of marketable crops (for example, kilograms of grain) produced per cubic meter of water consumed to grow that crop.
