The paper analyzes the determinants of vegetable market participation in Ethiopia. study procures data from primary and secondary databases. for this are collected producers through appropriate statistical procedures. Heckman two stages Econometrics model was applied to analyze data. Among factors affecting farmers decision, first stage Heackman results disclose that district, family size, irri...

Watershed management consists of multifunctional activities to manage and address the increasing water resource problems. Ever increasing water demand and rapidly depleting water resources, it has become necessary to develop the adaptation options to recharge groundwater resources. A watershed is a special kind of Common Pool Resources (CPRs); an area is defined by hydrological linkages where o...

planted annually, primarily in monoculture systems (TASS, 2002). Furthermore, about 5.5 million stocker Agriculture in the Texas High Plains depends heavily on irrigation cattle (about 25% of U.S. total; TASS, 2002; USDA with water withdrawn from the Ogallala aquifer at nonsustainable rates. Our hypothesis was that integrating crop and livestock systems Natl. Agric. Stat. Serv., 2003) are shipp...

Water shortage is a global problem that has severe implications on economic growth and societal well-being, even in the most developed countries. As more than two-thirds of freshwater consumed worldwide are used for irrigation, large quantities of freshwater can be saved by improving the efficiency of irrigation systems. Automatically scheduling irrigation events based on soil moisture measurem...

At present and more so in the future, irrigated agriculture will take place under water scarcity. Insufficient water supply for irrigation will be the norm rather than the exception, and irrigation management will shift from emphasizing production per unit area towards maximizing the production per unit of water consumed, the water productivity. To cope with scarce supplies, deficit irrigation,...

Agricultural irrigation in the middle reaches of the Heihe River Basin consumes approximately 80% of the total river water. Whether the irrigation depth matches the water uptake depth of crops is one of the most important factors affecting the efficiency of irrigation water use. Our results indicated that the influence of plastic film on soil water δ(18)O was restricted to 0-30 cm soil depth. B...
