| In order to create systematic database on farm households and speedy analysis, I have developed Automated Land Potential Evaluation System (ALPES) using MS Access program. ALPES helps in coupling the socioeconomic and biophysical data for integrated Land Use Planning and policy analysis. |

| Estimated the economic viability of soil survey information (1:12,500 scale ) to minimize the cost of production thorough site specific nutrient management in Garakahalli microwatershed, Karnataka State. The study found that the benefits of soil survey in site specific fertilizer management in finger millet with the Benefit Cost Ratio 1:2.85 and the additional income due to soil management of ₹ 1600 per ha. The soil information is useful in minimizing fertilizer cost and in enhancing farm income. The investment in soil survey and fertility management is economically viable at watershed level. |

| Study carried out at Rajankunte watershed between 1980 and 2002 showed the change in land use and nutrient use pattern resulted in increase in area under acid soils. Change in land use and management greatly affects the soil quality and require immediate correction measures like lime application and soil and water conservation measures including proper crop rotations to arrest the further degradation. The total cost of correcting soil acidity using lime worked out to be of Rs 218802 for the entire watershed and an average cost of Rs 761/ha for improving soil quality in Rajanukunte watershed.

| Estimated the Environmental and Economic Impact of the New Agricultural Policy of Karnataka on Land Use, Land Productivity and Rural Livelihood in Karnataka. It was found Increase in irrigated area leads to increase cropping intensification, decrease soil erosion, increasing soil carbon sequestration and increase in net returns per hectare . |

| Government of Karnataka has given project for land suitability mapping for identifying potential areas for food production. The available data on soil (1:250,000 scale ) and climatic information were used to evaluate crop suitability and mapping the land potential for agricultural production in Karnataka. By matching the crop requirement based on soil site suitability criteria, suitability ratings were given and maps were prepared using GIS technique. The land suitability maps for 26 priority crops were prepared for the Government of Karnataka. |
