Описание: Africa has been severely affected by droughts in the past, contributing to food insecure conditions in several African countries. In view of the (even more) severe drought conditions and water shortage that may be expected in sub-Saharan Africa in the coming years, efforts should focus on improving drought management by ameliorating resilience and preparedness to drought. This study contributes to the development of a modelling framework for hydrological drought forecasting in sub-Saharan Africa as a step towards an effective early warning system. The proposed hydrological drought forecasting system makes use of a hydrological model that was found to be suitable for drought forecasting in Africa and could represent the most severe past droughts in the Limpopo Basin. The modelling results showed that there is an added value in computing indicators based on the hydrological model for the identification of droughts and their severity. The proposed seasonal forecasting system for the Limpopo Basin was found to be skilful in predicting hydrological droughts during the summer rainy season. The findings showed that the persistence of the initial hydrological conditions contribute to the predictability up to 2 to 4 months, while for longer lead times the predictability of the system is dominated by the meteorological forcing.An effective drought forecasting and warning system will hopefully contribute to important aspects in the region such as water security, food security, hazard management, and risk reduction.

For integrated water resources management both blue and green water resources in a river basin and their spatial and temporal distribution have to be considered. This is because green and blue water uses are interdependent. In sub-Saharan Africa, the upper landscapes are often dominated by rainfed and supplementary irrigated agriculture that rely on green water resources. Downstream, most blue water uses are confined to the river channels, mainly for hydropower and the environment.
Over time and due to population growth and increased demands for food and energy, water use of both green and blue water has increased. This book provides a quantitative assessment of green-blue water use and their interactions. The book makes a novel contribution by developing a hydrological model that can quantify not only green but also blue water use by many smallholder farmers scattered throughout the landscape.
The book provides an innovative framework for mapping ecological productivity where gross returns from water consumed in agricultural and natural vegetation are quantified. The book provides a multi-objective optimization analysis involving green and blue water users, including the environment. The book also assesses the uncertainty levels of using remote sensing data in water resource management at river basin scale.

Описание: "This book addresses the hydrological processes of ASALs, climate change and variability, land use changes, floods and droughts, agriculture, integrated water resource management and sustainable development in the ASAL areas of the world. It addresses different aspects of Hydrology, climate variability, and water resources management and application of GIS and Remote sensing in ASAL areas"--
Water demand in southern Africa continues to rise, as urban areas expand and as agricultural water demand rises to meet the millennium development food security goals. Water resource availability in the northern Limpopo Basin has declined over the last 30 years, and will decline further under climate change. In this study, water resources modelling is used to quantify the effect of water resources strategies and climatic conditions on water resources availability. This is coupled with water balance modelling to evaluate the potential of alluvial aquifers, which form the beds of sand rivers.
The greatest benefit for the least impact comes from strategies providing for better land and soil/water management, such as changing from maize to small grains, production of livestock fodder and conservation agriculture. Small dams are a key resource to rural communities, and change to Multiple Use Systems through abstraction of water for irrigation has clear benefits locally. There is also great potential for the exploitation of alluvial aquifers for water supply. Better management of existing large dams, together with conjunctive use of alluvial groundwater and several reservoirs could increase productive use of water and significantly improve livelihoods without the construction of new reservoirs.
