COVID-19 and the call for 'Safe Hands': Challenges facing the under-resourced municipalities that lack potable water access - A case study of Chitungwiza municipality, Zimbabwe.

Billions of people living in developing countries lack access to safe drinking water, not to mention water for handwashing, one of the most effective ways to contain the fast spreading novel coronavirus (COVID -19). The recent global spread of COVID-19 has fostered diverse initiatives such as the 'Safe Hands' challenge led by the World Health Organization. Individuals are encouraged to regularly wash their hands for 40-60 s under running water with soap.

Exploring synergies in the water-food-energy nexus by using an integrated hydro-economic optimization model for the Lancang-Mekong River basin.

The Water-Food-Energy nexus study identifies developmental challenges and trade-offs present along the transboundary river basins. Intensive reservoir development for hydropower production impacts existing actors in the Lancang-Mekong River Basin. Concerns from these stakeholders highlight three major trade-offs that occur between hydropower and irrigation (HP-AG), hydropower and fisheries (HP-F), and irrigation and fisheries (AG-F).

A data set of inland lake catchment boundaries for the Qiangtang Plateau.

A catchment is the basic unit for studying hydrologic cycle processes and associated climate change impacts. Accurate catchment delineation is essential in the field of hydrology, environment, and meteorology. Traditionally, catchment delineation is most easily carried out where the outflow area can be easily determined because of a well-defined outlet.
