| The present study has examined land degradation and its impact on livelihood security of farm households. Specifically, it has estimated the impact of sodic soils at farm level in terms of resource use, productivity and profitability of crop production and has examined income, employment and household consumption behaviour for ensuring better livelihood. The study conducted in the Ramanathapuram and Tuticorin districts of Southern Tamil Nadu, is based on data collected from 160 affected and 80 non-affected sample households. Sources of productivity differences between affected and non-affected farming situations have been identified by decomposing the productivity changes. To find the relationship between income, household expenditure and activity... |

| Falling groundwater tables and depletion of economically accessible groundwater resources would have major social and economic consequences. The present study has been taken up with the overall objective of evolving optimal crop plans to sustain the use of groundwater resources for irrigation. Perambalur district was purposively selected for the study as it mainly depends on groundwater for its irrigation. Linear programming technique was used to evolve optimal crop plans. The constraints identified were primarily irrigation water, besides land availability during the cultivating seasons and capital. Six typical farms were selected, one each for the open well, wells in tank command area and tubewell-irrigated farms in critical and over-exploited... |
