An Economic Analysis of Public Interventions for Amelioration of Irrigation-Induced Soil Degradation 31
Chinnappa, B.; Nagaraj, N..
The study has reported the impact of public interventions for amelioration of soil degradation through subsurface drainage technology in the Tungabhadra Project area in Karnataka. The primary data, obtained from 105 farmers of TBP area, have been analysed using budgeting, discounted cash flow measures and gini ratio. The provision of subsurface drainage through public interventions, has increased the productivity of land appreciably (166 per cent) and has provided a source of regular income (Rs 13,636/ha from paddy) to resource-poor households. The technology has been found to be cost effective, socially acceptable and economically feasible. The equity analysis has indicated reduction in inequalities in income distribution during the post-drainage period....

Contract farming and its implications for input-supply, linkages between markets and farmers in Karnataka 31
Nagaraj, N.; Chandrakanth, Mysore G.; Chengappa, P.G.; Roopa, H.S.; Chandakavate, Pramod M..
This study is focused on the economic analysis of contract farming with a comparison of income, access to technology and credit of contract and non-contract farmers. The advantages of contract farming for smallholders have also been evaluated. In contract farming, quality inputs such as seeds, fertilizers and plant protection chemicals are provided to the farmers at their farm gate, coupled with the technical advice on production aspects. This not only reduces the working capital needs of farmers but also substantially reduces their transaction cost per unit of output. Borrowing of crop loans has been found 33 per cent higher by non-contract farmers than contract farmers, as the former have to buy material inputs. The net returns have been found higher for...

Cost Effectiveness of Rainwater Harvesting for Groundwater Recharge in Micro-Watersheds of Kolar District of India: The Case Study of Thotli Micro-Watershed 31
Nagaraj, N.; Pradhani, Umesh; Chengappa, P.G.; Basavaraj, G.; Kanwar, Ramesh S..
This study has estimated the supply augmentation of groundwater recharge due to creation of water harvesting structures and has assessed the cost-effectiveness of rainwater harvesting for groundwater recharge on watershed basis in one of the sub-watersheds of the Kolar district, Peninsular India — a typically hard-rock area. The study is based on the primary data for the year 2008-09 collected from a sample of 90 farmers having irrigation bore-wells in the selected watershed named Thotli. The study has indicated that the annual draft of irrigation water exceeds the annual recharge, causing a negative balance. On an average, the returns per rupee investment have been found to be ` 1.80 on farm pond, ` 1.78 on recharge pit and ` 1.39 on field bund. The cost...

Economic Analysis of Groundwater Markets in Central Dry Zone of Karnataka 31
Nagaraj, N.; Kumar, A.H. Suvarna; Chandrakanth, Mysore G..
Groundwater, unlike surface water, is expensive and relatively scarce and hence should be used to grow crops that are responsive to protective irrigation, require less water and are remunerative. Sellers and buyers of groundwater have put large areas under paddy, a water-intensive crop. This needs to be disciplined through effective groundwater institutions. Groundwater literacy has to be promoted by educating farmers on the pros and cons of overexploitation. For farmers who do not own wells, one way to enable access to water is through group investments in well irrigation. This would require provision for institutional credit for such groups and energization of pumpsets. This will provide an environment of sharing available groundwater and the associated...

EFFECT OF SAND MINING ON GROUNDWATER DEPLETION IN KARNATAKA 31
Hemalatha, A.C.; Chandrakanth, Mysore G.; Nagaraj, N..
Groundwater is a crucial source of irrigation for the farmers in Gauribidanur taluk to eke out the living since there is no other perennial source of irrigation. Currently the irrigation wells in the riparian areas of uttara Pinakini River are seriously threatened due to excessive sand extraction, which in turn affects the groundwater recharge. This has manifested in increase in proportion of well failure. It is imperative that sand mining is seriously (negative externality) affecting the interests of the economy of riparian farmers in this river basin. This calls for a serious, effective and efficient implementation of regulation of sand mining for the benefit of both agriculture and civil works. Currently sand extraction is permitted up to three feet by...

EQUITY IN DISTRIBUTION OF BENEFITS FROM WATER HARVESTING AND GROUNDWATER RECHARGE – AN ECONOMIC STUDY IN SUJALA WATERSHED PROJECT IN KARNATAKA 31
Seema, H.M.; Chandrakanth, Mysore G.; Nagaraj, N..
In this study, economic impact of water harvesting and groundwater recharging was analyzed in the context of Sujala watershed equity and efficiency in the distribution of benefits in Chitradurga district, Karnataka. Field data for 2004-05 (drought year) and 2005-06 (normal year) from 30 sample farmers in Sujala watershed form the data base for the study. Another sample of 30 farmers from Non-Sujala (or DPAP) watershed, and 30 from outside watershed area form the control. Farmers were further classified as: (i) those who had bore well irrigation; and (ii) those who had no borewell irrigation in order to assess the impact of watershed. It was found that the amortized cost per functioning well and cost per acre inch of groundwater in Sujala watershed is lower...

Equity Issues Relating to Irrigation-induced Soil Degradation under Left Bank Canal of Tungabhadra Project Area, Karnataka 31
Chinnappa, B.; Nagaraj, N..
The equity issues concerning soil degradation and soil reclamation have been analysed for Tungabhadra Project Area of the Karnataka state. The study is based on primary data obtained from 325 respondent farmers. The data gathered by survey method have been analysed using conventional and simple tabular method of analysis, Gini ratio, and Lorenz curve. The study has revealed that the small and marginal farmers are worst affected by soil degradation. The large farmers have also experienced the brunt of soil degradation but the effect has been marginal since they have alternative sources of livelihood. The study has further indicated that the extent of inequity is higher on degraded than normal soils. However, this can be reduced to a great extent by...

Externalities of groundwater contamination due to pollution and effects on human and animal health in Karnataka 31
Varuni, C.N.; Chandrakanth, Mysore G.; Nagaraj, N.; Srikanthmurthy, P.S..
In this study, negative externality due to distillery pollution on agriculture in Kabini command in Nanjanagudu taluk, Mysore District is estimated. The spent wash let in lagoons enables settling heavy metals to infiltrate soils, gradually affecting soil and health. The distillery opened during 1985 and farmers apparently began experiencing the negative externalities due to pollution from 1995. The groundwater extracted for irrigation was the first victim of distillery pollution rendering it unfit even for irrigation purposes. Paddy, sugarcane, Banana, Jowar, Mulberry, Coconut, Ragi are the major crops being grown in this command area. For this study, all the 35 distillery pollution affected farmers in the Distillery Dffluent Polluted Villages (DEPA,...

Geographical Indications for Kodagu Coffee – A Socio-economic Feasibility Analysis 31
Chethana, A.N.; Nagaraj, N.; Chengappa, P.G.; Gracy, C.P..
The feasibility of Geographical Indications (GI) for the Kodagu coffee has been explored, as the coffee is grown under shade and unique conditions in the midst of rich biodiversity; as a result, the productivity of coffee turns out to be relatively low. The results have indicated that productivity of coffee is lower (6 q/ acre) when grown under high shade and native tree cover than under low shade condition (8.9 q/acre). Although, the difference in cost of cultivation between the two shade conditions is not significant, the net gain is to the tune of Rs 10.40/kg for the planters growing under low shade and exotic trees cover. The net loss has been estimated to be around Rs 15.50/kg for the planters growing under high shade and native trees cover. The...

Groundwater markets and water use efficiency: The case of Karnataka 31
Deepak, S.C.; Chandrakanth, Mysore G.; Nagaraj, N..
This study, based on primary data collected from 120 groundwater users in eastern dry zone of Karnataka compares the water use efficiency among different categories of water users, viz. well owners who do not sell water, well owners who sell water either for agricultural or non-agricultural use and water buyers (both agricultural and nonagricultural). Some of the important findings are- • The cropping pattern varies between categories, with both the sellers and buyers preferring low water intensive mulberry crop, while the self user's category grew more water intensive crops. • Farmers who sold water for non-agricultural purposes earned the highest return (because of higher end-use price) and also made the most efficient use of water. Thus, making a point...

Hyperbolic discounting in analyzing investment in groundwater irrigation in India 31
Chandrakanth, Mysore G.; Rashmi, N.; Chandrashekar, H.; Nagaraj, N..
Researchers are often confronted with the choice of discount rate as well as the method of discounting for estimating the amortized cost of long-term investment in agriculture including groundwater irrigation. The obvious choice is to use the opportunity cost of capital, which is the prevailing interest rate of around 9 percent (compounded – exponential basis), charged on longterm agriculture loans. However, using the ‘exponential’ basis does not provide a realistic amortized cost of irrigation as it over estimates the value of investment due to ‘exponential’ basis as demonstrated above. In order to obtain an empirical estimate of this interest rate, using field data from farmers three dry agro-climatic zones of Karnataka (Shamsundar (1996), Sripadmini...

Bhat; Chengappa, P.G.; Mundinamani, S.M.; Shanmugam, T.R.; Chandrakanth, Mysore G..
Conceptual development in the theory of externalities have opened up several policy options for their internalization including payment towards environmental services. Hence as externalities are social costs, accountability is crucial in increasing environmental awareness and for collective action through education and extension more so in developing countries. Here a modest attempt has been made to estimate externalities in water, forests and environment with field data from peninsular India to reflect on the economic perception of externalities by farmers and users of environment for the consideration of policy makers to devise institutions for payment towards environmental services. The methodology largely used here in estimation / valuation of...
