Explanation:

The country is facing serious challenge because of extensive land degradation and water stress. Though the estimates may vary, it can be safely stated that nearly half of the country’s area is suffering from excessive runoff resulting in soil erosion and loss of precious water resources.
The main aims of IWMP (Intergrated Watershed Management Programme) are harnessing, conserving and developing degraded natural resources such as soil, vegetative cover and water; prevention of soil run-off; rain water harvesting and recharging of the ground water table; increasing the productivity of crops; introduction of multi-cropping and diverse agro-based activities; promoting sustainable livelihoods and increasing the household incomes.
The benefits that are expected to accrue under the IWMP include increase in availability of surface water & groundwater, changes in cropping pattern from one to two crops annually, increase in fodder availability and increase in milk yield, increase in agriculture productivity and increase in employment opportunities and household income.
