Climate change and its impact on water resources has brought serious concerns across the globe. Since 20th century, there is an overall increase in surface temperature by about 1◦C with some local areas experiencing an increase of up to 3◦C minimum temperature while rainfall trends indicated varying inconsistencies in both spatial and temporal scales. Changes in a rainfall patterns and intensity as well as gradual increase in temperature has caused changes on hydrological processes. Areas such as the Eastern and Southern African regions are the most vulnerable to climatic changes due to their low adaptive capability, high reliance on natural resources and underdeveloped agricultural production systems. These regions already experience floods, droughts and diseases causing fatalities, significant relocation of population and economic losses.
It is projected by 2050, that climate change will significantly impact macroeconomy of Eastern and Southern African countries, with a loss of 5–15% of GDP. Since the effects of climate change on water resources are not well known and varies from one region to another, it necessitates research to be done at local scales. Given the current hydro-climatic changes taking place, there is a need for efficient and effective water management based on an accurate assessment of the available water resources. This theme focuses on how best to utilize existing data and how newer technologies, such as remote sensing, local knowledge systems, and big data, can improve assessment of both surface and groundwater, including transboundary water resources. This has a pivotal role in contributing to the global agenda of sustainable development. By working together, we embrace and strengthen partnerships and adoption of multidisciplinary approaches for sustainable solutions in the water-climate space.
The papers in this sub-theme focus on addressing issues related to enhancing efficient and effective assessment of water resources, planning and management of surface and groundwater resources, and the impact of climate change on water resources and agricultural production using appropriate models or tools.
