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.

This study, Indus basin of Pakistan: the impacts of climate risks on water and agriculture was undertaken at a pivotal time in the region. The weak summer monsoon in 2009 created drought conditions throughout the country. This followed an already tenuous situation for many rural households faced with high fuel and fertilizer costs and the impacts of rising global food prices. Then catastrophic monsoon flooding in 2010 affected over 20 million people, devastating their housing, infrastructure, and crops. Damages from this single flood event were estimated at US dollar 10 billion, half of which were losses in the agriculture sector. Notwithstanding the debate as to whether these observed extremes are evidence of climate change, an investigation is needed regarding the extent to which the country is resilient to these shocks. It is thus timely, if not critical, to focus on climate risks for water, agriculture, and food security in the Indus basin of Pakistan.

The book looks into the domestic water issues and disputes in the Himalayan South Asian countries, and based on it analyzes trans-boundary water disputes. Himalayan South Asia comprises India, Pakistan, Bangladesh, Nepal, Bhutan, and Afghanistan. All except Afghanistan share river waters with India. Home to some of the major river basins of the world, a part of this region falls into water scarce zone, and according to the United Nations Water Report of 2018 some of them will experience severe water scarcity by 2050. The book also studies water issues in China. Though the country is not a part of the Himalayan South Asia, most of the major rivers of this region originate in China. Over the years, China has been alleged by countries like India for diverting, choking or using the trans-boundary river waters for its purpose. Understanding water competition and issues in China will help one to understand its transboundary water behavior.

The Nile Basin Initiative (NBI) is a remarkable achievement towards the cooperative management of the common Nile water resources. Based on a Shared Vision Program and a Subsidiary Action Program, the NBI has numerous ongoing projects on the ground. Research on the Nile water resources has been recognized to be crucial for successful implementation of the NBI projects. Therefore, IWMI and other research centers have worked together with the NBI to identify knowledge gaps pertinent to the Nile water resources. This report presents prioritized research questions, pertinent ongoing research projects and the implementing institutions; and available databases on the Nile.

This study aims at improving the hydrological process understanding of the semi-arid and transboundary Incomati river basin to enable better water management. Comprehensive statistical and trend analysis of rainfall and streamflow were conducted, and the Indicators of Hydrological Alteration tool was deployed to describe the streamflow regime and trends over time. Land use and land cover change, particularly the conversion of natural vegetation into forest plantation, the expansion of irrigated agriculture and the flow regulation due to dam operation were identified as critical drivers of flow regime alteration. Hydrograph separation using long-term hydrochemical data at seasonal scale, and hydrochemical and isotope data at event scale were performed to quantify runoff components. A novel methodology to calibrate recursive digital filters using routinely collected water quality data was developed and tested in the catchment. This method allows for estimation of daily baseflow from readily available daily streamflow data. Dominant runoff generation zones were mapped using the Height Above Nearest Drainage approach. The hydrological model STREAM was then employed, informed by the runoff generation zones mapping and the process understanding gained in the catchment, as well as remote sensing data. The study provides the basis for better operational water management in the catchment.
