This paper briefly synthesizes recent research illustrating how smartphones, sometimes in conjunction with other sensors, present a nexus point method for citizen scientists to engage with and use sophisticated modern technology for water quality monitoring.

Achieving gender equality in irrigation can result in greater production, income, and job opportunities for both men and women smallholder farmers from diverse social groups, while building climate resilience in sub-Saharan Africa.

In many low- and middle-income countries, sewage sludge generated from wastewater treatment systems has potential environmental and health hazards.

This study evaluates the socioecological consequences of the potential trade-offs between maintaining environmental flows (e-flows) and providing water for sustainable subsistence agriculture and livelihoods to the vulnerable human communities living along the lower Great Letaba River in South Africa.

Arab countries in the Middle East and North Africa (hereafter called “the region”) generate around 21.5 billion cubic meters (BCM) of municipal wastewater each year.

Maintaining the state or health of rivers is a vital part of sustainable development. Healthy rivers are able to support and maintain key ecological processes and thus ecosystem services on which society depends.

As this book highlights, the number of (direct) water reuse projects has doubled every decade since 1990, and there are more than 400 operational projects now in the MENA region. Nevertheless, the potential for resource recovery from municipal wastewater in the MENA region is still untapped.

Living customary water tenure is the most accepted socio-legal system among the large majority of rural people in sub-Saharan Africa.

Rapid climate change is causing weather extremes in every region of the world. The global water cycle is now experiencing a structural change not seen since the last Ice Age, leaving human systems struggling to adapt and respond.

The Constitution of Nepal 2015 enshrines everyone’s right of access to clean water for drinking and the right to food. The common operationalization of the right to water for drinking is providing access to infrastructure that brings water for drinking and other basic domestic uses near and at homesteads.
