1. Hydrological effects of water harvesting techniques
Sammanfattning : The thesis investigates hydrological effects of large-scale water harvesting techniques on local water balances as well as sediment erosion. The techniques of tabias, soil contour ridges and small hill reservoirs are investigated. Pertinent processes are observed and simulated using various hydrological models.. LÄS MER
2. Rain Water Harvesting (RWH) North of Iraq
Sammanfattning : Rainwater harvesting is one of the methods that can ensure availability of water for winter crop in Iraq. Using this technique the excess rainwater (runoff) is stored in reservoirs of dams of different sizes. The water from these reservoirs can be used later when required to satisfy the crops requirements. LÄS MER
3. Rain water harvesting and supplemental irrigation at Sinjar district in northwest Iraq
Sammanfattning : Rainwater harvesting is one of the methods that can ensure availability of water for winter crop in Iraq. Using this technique the excess rainwater (runoff) is stored in reservoirs of dams of different sizes. The water from these reservoirs can be used later when required to satisfy the crops requirements. LÄS MER
4. Marginal and Virtual Water for Sustainable Water Resources Management in Syria
Sammanfattning : Arid and semiarid Middle Eastern countries generally, and Syria in particular, face serious water shortage problems and challenges with water sustainability. Climate change, population growth, and economic development play a major role in decreasing available water resources per capita. LÄS MER
5. Traps and transformations : Exploring the potential of water system innovations in dryland sub-Saharan Africa
Sammanfattning : In semi-arid and dry sub-humid sub-Saharan Africa (SSA), high poverty levels and a heavy reliance on small-scale rainfed agriculture make rural livelihoods difficult. Upgrading current farming systems, in a way that safeguards productivity beyond field-scale, is urgent. LÄS MER
