This study constructs a simulation model to evaluate the potential for conflict among residential and agricultural users of water in southern Rhode Island. The model estimates the profitability of irrigation of turf farms and projects the total use and the economic value of irrigation water. The results indicate that the economic value of irrigation water compares favorably with current residential water prices in the area. In addition, substantial demand for irrigation water is projected. Given current rates of growth in turf acreage and residential water use, there appears to be a significant potential for conflict, particularly given the absence of well developed institutions for allocating water among users.

This study investigates the economic value of irrigation water using data collected from 200 smallholder producers in Makhathini and Ndumo areas, KwaZulu-Natal.The study accounts for psychological capital (individual mind-set and attitude affecting motivation to take initiatives) as an important aspect of farm management. This concept focuses more on the ‘soft’ aspects of farm management, which have not been adequately studied in the context of smallholder farming. A sustainable livelihoods framework is employed as a conceptual framework and the role of psychological capital is integrated to explain the variation in water values. The study employs the residual valuation method to estimate water values, principal component analysis to generate an index for psychological capital, and the general linear model to explain variation in water values. The findings suggest that variation in water values was mainly influenced by the location of the farmer, farmer type, physical capital, social capital, land size, farming experience, crop type and psychological capital. The results reinforce the importance of institutional arrangements and collective bargaining as an important element of managing a smallholder farm to increase the economic value of water. To build and develop positive psychological capital for smallholders, it is recommended that government should re-visit the usual model of ‘hand-outs’ (input, finance). It is time to re-consider direct farmer support that entails being heavily involved in their day-to-day activities (i.e., purchasing inputs and running the irrigation schemes on their behalf). Going forward, the focus should rather be on enabling them to change their behaviour to be self-reliant and own their own destiny through on-farm and off-farm economic activities. Moreover, government and other development partners have to understand the long-term behavioural impact (on farmers) of what they do, for instance, entrenching expectations.

The Impact

AbstractEstimation of the economic value of irrigation water is complicated by a lack of data on the price or marginal cost of water. Through econometric estimation of an aggregate total value product function, this paper obtains marginal irrigation water value estimates for the Middle Atlantic region. Additionally, the impact of temperature and soil conditions on aggregate production within the region is estimated. Ridge regression and covariance analysis are employed to deal with problems of multicollinearity and simultaneous equation bias, respectively. Estimates indicate a substantial and growing return to irrigation within the region.

AbstractThe water shortage issue may put a spotlight over most of the Middle East region and push many nations to re-planning the water resources in various respects. Providing data on water’s economic value assists policymakers make informed decisions regarding water distribution. Additionally, addressing the increasing demand for all uses and building the sustainable future of agricultural and water policies. The purpose of this article is to explore and evaluate the economic value of irrigation water in Sharkia Governorate, regarded one of Egypt’s largest provinces. It also examines how to maximize the economic value of irrigation water, taking into account the self-sufficiency of main crops. Furthermore, consideration has been given to the political demands for the allocation, management and control of water resources. The simulation software Operational, Planning and Distribution Model (OPDM) was used to simulate through the studied province the accessible water distribution and crop yield. Moreover, it is used to judge the impact of irrigation water utilization and to check gross income. Furthermore, from a technical and economic point of perspective, the distinct suggestions were contrasted. The research evaluates the present crop pattern for wheat and cotton attaining a peak economic value of 1.23 EGP/m3 and 0.98 EGP/m3 of irrigation water for wheat and cotton respectively. Moreover, it reaches 0.41 EGP/m3 for rice which considered one of the highest plants in water consumption. Finally, these findings may highlight some strategic crops future development.
