Environmental flows (EF) are an important component of Goal 6 (the ‘water goal’) of the Sustainable Development Goals (SDGs). Yet, many countries still do not have well-defined criteria on how to define EF. In this study, we bring together the International Water Management Institute’s (IWMI’s) expertise and previous research in this area to develop a new methodology to quantify EF at a global scale. EF are developed for grids (0.1 degree spatial resolution) for different levels of health (defined as environmental management classes [EMCs]) of river sections. Additionally, EF have been separated into surface water and groundwater components, which also helps in developing sustainable groundwater abstraction (SGWA) limits. An online tool has been developed to calculate EF and SGWA in any area of interest.

Climate change is increasing the frequency and severity of droughts in semi-arid regions. Small-scale water storage can help build drought resilience, particularly in rural areas with no access to formal water infrastructure. Sand dams, which store water by capturing water in sand-filled ephemeral rivers during the wet season, are one promising storage option. While emerging studies indicate tentative evidence of their benefits, the focus on resilience is under-addressed. This study evaluates the impact of sand dams on resilience to climate variability and changes through a participatory case study approach in the Shashe catchment, a semi-arid catchment shared by Botswana and Zimbabwe. Participatory research was conducted via site inspections, focus group discussions, and interviews at 20 sand dams utilized by 19 villages across the Zimbabwean portion of the Shashe catchment. The results show that sand dams significantly improved local water availability, most notably with a significant increase in the number of months per year that water could be collected from the dam site (mean = 6.5 months before, to mean = 10.9 months after construction, p < 0.05). This increase is also reflected in drought years (mean = 5.8 months before, to mean = 9.6 months after construction, p < 0.05). Sand dams also contribute to the adaptive capacity of communities via key benefits such as diversification of livelihood activities, improved health and hygiene, and reduced erosion in the surrounding area due to increased vegetation. In sum, the study demonstrates clear benefits to communities facing drought, supporting calls to elevate sand dams on the development agenda.

The main objectives of this study were to assess the prevalent and most challenging climate risks in the Zambezi River Basin countries, understand the role of digital technology in climate adaptation, and thereby propose interventions to accelerate and scale up the use of digital technology in climate adaptation for small farmers and businesses. The report is based on the findings of the rigorous literature review, analysis of secondary data, and a series of stakeholder consultations conducted in 2023. According to the findings, the nature and extent of climate risks in the Zambezi basin countries vary across the countries, and the severity is increasing over time, calling for context-specific solutions. The extent, popularity, and use of digital technologies in climate adaptation are in their infancy but vary across countries and are increasing in use. The most frequently used digital technologies with the potential for climate adaptation include radios, satellite televisions, mobile phones, drones, computers, mobile applications, and data-enabled insurance services. However, the adoption and scaling of digital technologies are replete with many constraints and challenges, mostly related to availability, access, affordability, issues related to gender and social inclusion, absence of an appropriate enabling environment, poor macroeconomic conditions, cultural and family norms, and poor user skills. Adopting data-enabled technologies is constrained by low digital penetration, high mobile data costs, low levels of literacy, cyber-safety concerns, and poor requisite infrastructure. The study recommends measures needed to address the issues related to the enabling environment, capacity, skills, and technological characteristics. It is important to continue awareness campaigns and skill development programs through formal and informal education systems at national and regional levels to enhance knowledge and skills on the availability, relevance, and use of digital technologies. A regional framework on digitization and a stringent cyber security regulatory framework for the region and its member states are needed. Measures are proposed to reduce digital technologies and increase affordability. Addressing the gender disparity associated with ownership of mobile phones, usage skills, and financial access, may liberate women from cultural barriers that prevent them from using mobile technology for livelihood activities. Non-farm income, including remittances and other sources of resilience, is important and should be supported in program design.
