Abstract

Sugar producing regions in India have more than 80 percentage groundwater irrigation through deep-well pumping. Whereas, NASA's gravity recovery and climate experiment satellites have revealed faster depletion of groundwater stocks in India. These areas are cultivating 93 percentage of sugarcane. This research is a comparative study and has attempted to estimate the economic value of irrigation water and the benefits of water and energy that can be saved through adoption of improved irrigation technologies. The economic value of each ha. cm of irrigation water for sugarcane was also worked out. Including additional area under irrigation with the water saved should be recommended only in safe and semi-critical regions to prevent 'rebound' effect.

Keywords

Abstract

The demand for fertilizers in India is being supplied with humongous import of fertilizer apart domestic production. The price of fertilizers both controlled (Urea 'N') and decontrolled (phosphorus 'P' and Potash 'K') are regularised by the Government with subsidy. Around 30 per cent of total subsidy bill in Union Budget (2014-15) is allocated for fertilizer subsidy in India. The study has the objective to impart the importance of fertilizer subsidy bill in India with reference to farmers and production of sugarcane. The study with the carefully forged research, attempted to find the private cost, social cost of fertilizer, Resource Use Efficiency (RUE) of essential nutrients with and without subsidy; and production loss when the subsidy is withdrawn by the Government. The fourth advances estimate of India on sugarcane production is 350.02 m. tones but when the subsidy bill on fertilizer is withdrawn then our production will be short by around 53 m. tonnes. To substantiate, the RUE will decline when fertilizer subsidy is withdrawn. Likewise, adoption per cent of drip irrigation will decline when micro-irrigation subsidy is withdrawn by the Government.

Abstract

Soil degradation is responsible for converting fertile agricultural lands into unproductive barren lands reducing productivity causing economic loss to the farmer and food insecurity. Degradation of land in any form diminishes the area of quality land available for agriculture resulting in greater yield variability, and thus, greater costs to risk-averse marginal farmers. Soil alkalinity is one such major form of degradation and causes upto 84.10 per cent of yield loss depending on intensity. In this context, the study examines the economic sustainability of farmers through soil reclamation. Though the cost of cultivation is increased due to adoption of reclamation, the economic loss due to alkalinity can be reduced by around 52 per cent and the net returns can be increased by around 1.5 per cent by reclamation. Investment on land and water must be viewed as investment on sustained food security, income, prosperity and environmental health. In this study salinity and alkalinity are used interchangeably.

Abstract

Rapid land use change has taken place in Tamil Nadu over the past three to four decades due to accelerated cultivation, industrialization and urbanization. Growth of population influenced increased food requirements. In order to meet the basic requirements, the Government has planned to increase the irrigation facilities and the agricultural inputs, (High yielding varieties (HYV), seeds, agricultural implements etc.) to the farmers and also implement the interventional schemes and incentives to enhance farmer’s income. Land use change may be examined by considering conversion of forest to crop and rangeland; losses of productive land through various factors; conversion of wetlands to agriculture and urban use: and conversion of other types of land to various human uses. The key to meet the present day challenges lies in the integrated management of the natural resources. Therefore, the knowledge of soil and land resources with respect to their spatial distribution, characteristics, potentials, limitations and their suitability for alternate land uses helps in formulating strategies to obtain higher productivity on sustained basis. With these views in mind an attempt has been made to study the spatial and temporal changes in the land use in Tamil Nadu.

Abstract

Watershed development projects have been taken up under different programmes launched by Government of India, State departments and also International Agencies. Watershed management is a concept which recognizes the judicious management of basic resources of soil, water and vegetation, on watershed basis, for achieving particular objective for the well being of the people. Realizing the significance of the watershed development investments on various watershed projects, a detailed study was carried out to evaluate the activities and their impacts. The impact of various activities on different aspects such as water resources, agricultural production, socio-economic aspects and institutional aspects was studied. The overall impact of watershed projects implemented under NABARD Watershed Development Fund (WDF) in Chikkanankuppam has been positive and significant.
