Watersheds

The Zambezi Riparian Region (ZRR) is a lifeline and home to ∼40 million people who depend heavily on the river basin for their livelihood. It also furnishes 8 of its riparian countries with goods and services on which hydropower production and food security anchor. The sustainability of the ZRR is threatened by extreme climate events. Here, we interrogate consecutive dry days (CDDs), an effective metric of extreme climatic events with implications on drought-driven water availability. We use ensemble empirical mode decomposition (EEMD) to understand CDDs.
Water resources are an essential and determining factor for food production, ecosystem health, and socio-economic development. The socio–economic water cycling system is a complex adaptive system. Changes in the socio-economic system at the macro level, such as industrial transformation, technical progress, and water price reform, will have impacts on water resources utilization at the micro level.
