The work reported here describes the water distribution patterns in sandy loam and silt loam soils under surface and micro-irrigation at different temperatures simulating the arid region conditions such as those experienced in the Balochistan Province of Pakistan. Specific consi…
This study is based on the hypothesis that shortage of dissolved oxygen at and below the water table and extraction of groundwater by irrigation wells at a rate greater than the aquifer recharge rate are the main causes of arsenic release in the groundwater of Bangladesh. The ma…
Water scarcity is a growing problem world wide. Economists uniformly suggest water pricing to improve water use efficiency; however, governments tend to reject that advice due to political risk, and economic and cultural concerns. This dissertation addresses questions of what po…
Arid and semi-arid countries are facing the exhaustion of their water resources and are being forced to use saline water (brackish groundwater and drainage water) for irrigated agriculture. The result is often disastrous as extensive productive regions become salinized. Neverthe…
Guinea, Mali, Mauritania and Senegal have conducted several efforts to develop the resources of the shared Senegal River basin. Because of poverty in the region, the development of the river basin's resources remains a major concern of authorities of the four countries, their po…
Poor public sanitation is one of the principal problems of towns in developing countries. The situation is deteriorating steadily with rapidly advancing urbanization and the lack of adequate infrastructures for the collection and treatment of wastewater. As a result, water-borne…
How to manage effectively natural resources on earth has been a major concern of social scientists and policy makers. A dominant approach towards the management of natural resources takes for granted that a common property regime will eventually lead to resource degradation or e…
In the Central Asian republic of Uzbekistan, mismanagement of irrigation has created immense environmental and economic problems. Canal systems are poorly constructed and maintained, delivery and application efficiency is low, and soil and water degradation is widespread. The di…
Insofar as drought characterises the Sahel climate, irrigation has provided the only alternative in developing a viable agriculture. Faced with the ever increasing and varied needs for water consumption, development of a hydro-agricultural infrastructure is a relevant and approp…
Irrigation water shortages have lately been a main area of concern for policy makers and planners in Pakistan. Current literature on the country's water resources predicts an alarming situation regarding the availability of irrigation water in the future due to declining water t…
The discharge of untreated domestic wastewater results in well-documented environmental health hazards. In many poor areas of the world the costs of constructing, operating, and maintaining mechanized wastewater treatment facilities is prohibitive. Given limited resources and co…
UAE is located at the southeast of Arabian Peninsula. Two main aquifers occupy the study area: the Eastern Gravel Plain and Ophiolite aquifer. Increasing salinity of groundwater and depletion of aquifers are a major concern in the UAE. Previous studies suggest that groundwater, …
Estimating the relative contribution of heavy metals and nutrients loads from diffuse and point sources and various hydrological pathways is a major research challenge in catchment hydrology. Understanding of the transfer, loads and concentration of these loads in basins is usef…
Spate irrigation is a flood-based irrigation, a special type of irrigated agriculture that has been practiced in arid and semi-arid regions for centuries. The irrigation is based on diverting into the low lands the highly variable and unpredictable flash floods from valleys and …
To address the problem of water scarcity and to achieve food self-sufficiency, huge efforts and massive irrigation developments have been made in the last twenty-five years by the Ethiopian Government. However, the performance of many small-scale irrigation (SSI) schemes is stil…
The central question of this research is why users of the irrigation system in Sindh, Pakistan do not organize to collectively manage this vital and scarce resource. The research tests the central hypothesis that recent changes in the agrarian structure of rural Sindh, embedded …
This thesis examines whether and under what conditions the recent decentralization of irrigation management in Turkey can deepen democracy through a comparative study of irrigation management decentralization in two provinces in Turkey: Urfa and Aydin. In Turkey, the state agenc…
Using the Wadi Sana watershed of Hadramawt Governate, Yemen as a case study, this dissertation examines how environmental and social factors structured the origins of irrigation in prehistoric Southwest Arabia. It applies three methods, archaeological survey, geomatics, and ethn…
