    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 launching land reclamation programmes. Therefore, the study has suggested that the government should initiate land reclamation programmes on a large scale on long-term basis so that the fruits of land reclamation technologies could reach the vulnerable sections of the society.Agricultural and Food Policy,

    An Economic Analysis of Public Interventions for Amelioration of Irrigation-Induced Soil Degradation

    Get PDF
    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. The study has suggested that the government should aim at encouraging and educating the affected farmers in adopting subsurface drainage technology on a large-scale.Land Economics/Use, Resource /Energy Economics and Policy,

    Groundwater markets and water use efficiency: The case of Karnataka

    Get PDF
    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 that end-use pricing is a key in shaping marginal productivity of water. • Compared to the self-users, farmers selling water for either agricultural or non-agricultural purposes realized higher marginal productivity. Thus,groundwater markets acted as an effective tool in enhancing efficient use of a scarce resource.This study explores efficiency and equity in groundwater markets in the hard rock areas of Karnataka. It compares the water use efficiency of farmers using groundwater for irrigating their land and also selling it for agricultural purpose (WSA, n=30), farmers using water for irrigating their land and also selling for non-agriculture purpose (WSNA, n=15), farmers who do not either sell or buy water but use it on their farms (WO, n=30), farmers who are buying groundwater for agriculture purpose (WBA, n=30), and buyers of water for non-agriculture purpose (WBNA, n=15). The Nash equilibrium framework describing the bargaining power of buyers and sellers of groundwater is used. Sidlaghatta taluk in eastern dry agroclimatic zone (EDZ) of Karnataka is chosen because it supports intensive groundwater markets. The objective of the study is to find out water use efficiencies among different groups of water users with the hypothesis that WSNA obtain higher water use efficiency than WSA, WBA, and WO.Groundwater markets, efficiency, equity, Resource /Energy Economics and Policy,

    Impact of water harvesting on groundwater recharge, productivity and net returns with integrated farming systems approach in eastern dry zone of Karnataka

    Get PDF
    The paper evaluates the performance of water harvesting structures by looking at the case of the Sujala watershed in Karnataka. The water harvesting structures have facilitated the rejuvenation of failed wells and enhanced the water yield. About 75% of the failed bore wells were rejuvenated as against 66% in the non- watershed. The yield of bore wells were increased by 21% in the watershed where as in non-watershed area the water yield has reduced by 11%. Investment analysis of water harvesting structures indicated that for every rupee of present investment on water harvesting structure there is a return of Rs. 2.79 in farm pond and Rs. 2.19 in recharge pits. Further, productivity of crops has enhanced through protective irrigation given at critical stages of crop growth and moisture conservation, which in turn increased the net returns of the farmer.Length: pp.764-774Water harvestingGroundwater rechargeWatershedsDevelopment projectsCostsFarming systemsArid zonesWellsIrrigation waterCase studies

    Hyperbolic discounting in analyzing investment in groundwater irrigation in India

    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 (2001), Chaitra (2002), Rajendra (2003)) nominal investment per irrigation well is considered (Table 3). The nominal investments were deflated using the index number of wholesale prices (1993-94 base year). Considering nominal and real growth in investment per irrigation well between the 1980’s and 2000’s in the three agro-climatic zones of Karnataka, using the exponential discounting, the nominal investment per well is found to be increasing between 3.7 and 5.7 percent. This shows that the amortization of groundwater investment cannot exceed say six percent. The real (exponential rate of) interest is computed by deflating the initial year investment and the terminal year investment per irrigation well using the 1993-94 as base all India wholesale price index numbers. It is found that in real terms the investment per well is falling between –2.5 percent and –0.17 percent.(Table 3). The fall in real investment is due to increased competition by rig owners in offering almost uniform rate of drilling over the years in several aquifers of Karnataka. For instance the price of drilling has been between Rs. 35 and Rs. 50 per feet between 1985 and 2005 for shallow bore wells. The phenomenon may not be very different in other states of peninsular India. A comparison of nominal investment in terminal year and the estimated cost of well in 2005 indicates that in EASTREN DRY ZONE the nominal interest rate is 3.7 percent, the real interest rate is –0.17 percent and the investment per well in 2002 (terminal year) being Rs. 53,478 and in 2005 (current year) being Rs. 59578 are comparable. But in CENTRAL DRY ZONE, while the nominal investment per well in 2000 is Rs. 45,000, the estimated investment in 2005 is Rs. 59,193, which is an unrealistically high exponential growth obtained by compounding the initial investment of Rs. 18,480 from 1984 to 2005. Similarly in EASTREN DRY ZONE, while the actual investment per well in 2000 is Rs. 75,095, the estimated investment per well in 2005 works to Rs. 97,702, which is again unrealistic. As the real interest rate is negative in irrigation wells, this could be one of the reasons for mushrooming of irrigation wells in Karnataka, since this makes investment affordable across different classes of farmers. Thus this analysis has two messages. One, that the nominal interest rate which has to be considered for amortizing investment on irrigation well can be around 3 to 6 percent, and that the real investment per well is falling.hyperbolic discounting, groundwater, exponential, Environmental Economics and Policy, Institutional and Behavioral Economics, Research Methods/ Statistical Methods, D9, Q25, M4,

    Geographical Indications for Kodagu Coffee – A Socio-economic Feasibility Analysis

    Get PDF
    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 marginal loss in the productivity of coffee due to shade is not directly reimbursable through the shade benefits. Hence, the coffee planters need to be compensated through a price premium for their products produced under rich biodiversity, thus requiring the GI that ensures quality and price.Agricultural and Food Policy,

    Economic Analysis of Groundwater Markets in Central Dry Zone of Karnataka

    Get PDF
    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 costs. The functioning of groundwater markets in hard rock areas of the semi arid dry zone of Karnataka show two types of arrangements. In the first one, irrigation services are provided on demand and water charge is levied on hourly basis. In the second one, irrigation services are provided for the whole crop season, and cash equivalent of a fixed share of crop produce is paid as water charge. For water buyers, crop sharing arrangement yielded higher returns than that under hourly rates. Comparative analysis of allocative efficiencies of input use for sellers and buyers in groundwater markets show that water buyers obtain higher economic efficiency in water used for crop production than sellers, though both buyers and sellers are growing water-intensive crops such as paddy.water markets, Resource /Energy Economics and Policy,

    Equity in distribution of benefits from water harvesting and groundwater recharge: an economic study in Sujala Watershed Project in Karnataka

    Get PDF
    The paper looks at the impact of water harvesting programs in ground water recharge through the case of the Sujala watershed in Karnataka. On comparison with areas of non sujala watershed and non watershed cases in one normal rainfall and one drought year, it was revealed that Sujala has been successful in recharging groundwater, improving farmers’ incomes and increasing crop production. Further the program is inclusive and the benefits were accrued even to the small and marginal farmers. In fact the net return for small and marginal farmers was higher that that for large and medium farmers. The study concluded that there is potential for expansion of Sujala pattern of watershed development program in other parts of Karnataka and India.Length: pp.720-746Water harvestingGroundwater rechargeWatershedsDevelopment projectsGroundwater irrigationWellsEconomic impact
