1. Irrigation water management : A performance study of the Rahad scheme in Sudan, 1977-1996
Abstract : The central objectives of this study is to assess the performance of irrigation water management of the Rahad scheme in Sudan between 1977 and 1996. The study assesses how well the scheme has succeeded in achieving irrigation management objectives using the criteria of productivity, equity, cost recovery and environmental stability. READ MORE

2. Hydro-climatic changes in irrigated world regions
Abstract : Understanding of hydro-climatic changes in the world’s river basins is required to ensure future food security. Different regional basins experience different levels of hydro-climatic change depending on the endorheic or exorheic nature of a hydrological basin, along with the climatic conditions and human land and water-use practices, for instance for irrigation.

3. Climate and geographical influence on the performance of infiltration-based facilities for managing runoff – Temporal and spatial variability
Abstract : Climate change is expected to lead to more intense and severe rainfall events in the future, significantly increasing the risk of urban flooding. This change, characterized by spatial and temporal shifts in precipitation patterns, presents a challenge to the capacity of existing urban drainage systems, which may lead to higher runoff volumes than they were initially designed to handle.

4. Irrigation with saline water using low-cost drip-irrigation systems in sub-Saharan Africa
Abstract : In the scope of future population support, agricultural productivity, in particular in sub-Saharan Africa, has to increase drastically to meet the UN’s millennium development goals of eradicating extreme poverty and hunger by 2015. Water availability in the root-zone limits crop production in large parts of the developing world. READ MORE

5. Irrigation and horticultural practices in ornamental greenhouse production : implementation of scientific knowledge into irrigation practices and methods
Abstract : Irrigation in greenhouse pot plant production is traditionally managed using a tactile perceptual method. This method, in this thesis called ‘the golden grip’, is based on the grower’s experiential knowledge where water requirement is determined by combining the estimated weight of the pot (both growing medium and plant) with factors such as plant age, developmental stage and size in combination with prevailing and future climate conditions.
