Accounting for water use and productivity AgEcon
Molden, David J..
This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level such as an irrigated field or household, a service level such as an irrigation or water supply system, and a water basin level that may include several uses. Water accounting terminology and performance indicators are developed and presented with examples at all the three levels. Concepts and terminologies presented are developed to be supportive in a number of activities including: identification of opportunities for water savings and increasing water...

Adaptation Of Integrated Irrigation System To Mitigate Climate Change With Respect To Gender-Sensitive CIGR Journal
Dawit, Meseret; Dinka, Megersa Olumana.
Water shortages due to climate change are becoming a global concern. Hence, improved irrigation technology resulted in water saving and reduce workload of women by ensuring investment returns. This study aims at investigating the effects of the adoption of drip irrigation combined with hand-dug wells on crop water productivity and crop yield of smallholder farmers and their perception of the scheme over two cropping seasons at Haramaya districts, Ethiopia. It was observed that the integrated irrigation system is an efficient and cost-effective method to improve crop productivity. Consequently, the drip irrigation system with water supply from hand-dug wells is recommended as a flexible system that can accommodate a variety of farm sizes and particularly...

Bailout with white revolution or sink deeper?: groundwater depletion and impacts in the Moga District of Punjab, India. AgEcon
Amarasinghe, Upali A.; Smakhtin, Vladimir U.; Sharma, Bharat R.; Eriyagama, Nishadi.
Moga District in Punjab, India, is a microcosm of the twin story of irrigation-induced growth and stress. The groundwater consumptive water use in agriculture exceeds the recharge by a substantial margin. Rice production contributes to a major part of this difference. The groundwater depletion is so critical that diversifying agriculture is the only way forward for sustainable agricultural growth. Reducing the rice area and intensifying milk production will be a win-win situation for both the farmers and the area reeling with a groundwater crisis.

Basin-level use and productivity of water: examples from South Asia AgEcon
Molden, David J.; Sakthivadivel, Ramasamy; Habib, Zaigham.
Discusses and illustrates concepts for identifying ways of improving productivity of water within basins. The results of applying a water accounting procedure to four sub-basins in South Asia (Bhakra in India; Chishtian in Pakistan; Huruluwewa in northern Sri Lanka; and Kirindi Oya in southern Sri Lanka) are presented. The methodology used identifies the quantities and productivity of various uses of water within a basin. This information is then used to identify the water-saving potential, and the means of improving the productivity of the managed supplies.

Does anybody give a dam? The importance of public awareness for urban water conservation during drought AgEcon
Aisbett, Emma; Steinhauser, Ralf.
Demand management has been of interest in dry climates such as Australia, Spain and the Western United States for decades. It is particularly important to understand policy options during drought conditions, as drought periods have a disproportionate effect on supply infrastructure decisions. While water‐conservation campaigns aimed at inducing voluntary consumption reductions are almost universally employed by water managers in times of supply constraint, voluntary measures are generally dismissed in the economics literature as ineffective. We argue that the robust positive correlation between dam levels and consumption after controlling for policy changes suggests that there is a significant component of voluntary conservation. Furthermore, omitting dam...

Economic Change and Environmental Issues: Policy Reforms and Concerns in Australian Agriculture AgEcon
Tisdell, Clement A..
Since the closing years of the 1980s, Australia has adopted structural adjustment policies designed to foster economic liberalism based on the market system. Today, there is little economic protection for Australian agriculture and Australia is a persistent advocate of free international agricultural trade. The natural Australian environment is not very favourable for agriculture because of low and erratic levels of rainfall and poor soils. Scarcity of water in Australia is growing and its use has become a major natural resource issue. Water availability and use of water by Australian agriculture is discussed, its environmental impacts are considered and the scope for using market systems to allocate water effectively are discussed. Other...

Economics and politics of water resources development: Uda Walawe Irrigation Project, Sri Lanka AgEcon
Molle, Francois; Renwick, Mary E..
The Uda Walawe Irrigation and Resettlement Project (UWIRP) located in the Southern dry zone of Sri Lanka was initiated in the early 1950s. The original plan for the UWIRP was a highly ambitious social, economic and physical engineering project aimed at creating a modern, profitable agriculture sector. This report examines the history of water resources development and investment decisions for the UWIRP over a period of 50 years and uncovers underlying processes that shaped the evolution of the project and highlights the limitation of viewing development as a mere set of technical and social engineering endeavors.

Ethanol and a Changing Agricultural Landscape AgEcon
Malcolm, Scott A.; Aillery, Marcel P.; Weinberg, Marca.
The Energy Independence and Security Act (EISA) of 2007 established specific targets for the production of biofuel in the United States. Until advanced technologies become commercially viable, meeting these targets will increase demand for traditional agricultural commodities used to produce ethanol, resulting in land-use, production, and price changes throughout the farm sector. This report summarizes the estimated effects of meeting the EISA targets for 2015 on regional agricultural production and the environment. Meeting EISA targets for ethanol production is estimated to expand U.S. cropped acreage by nearly 5 million acres by 2015, an increase of 1.6 percent over what would otherwise be expected. Much of the growth comes from corn acreage, which...

Evaluation of historic, current and future water demand in the Olifants River Catchment, South Africa AgEcon
McCartney, Matthew P.; Arranz, Roberto.
Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were...
