Welcome to Africa Water, Sanitation & Hygiene

Africa Water, Sanitation & Hygiene is a bi-monthly magazine and is designed to address Africa’s water and sanitation issues, look for solutions and strategize for the future’s long term sustainability for water resources development. It is a hub of knowledge sharing and development and also dissemination of information to all the stakeholders in the water sector down to the community level. The publication also focuses on a vast array of environmental and health lists that may periodically address water resources issues.

 water and energy

Water and energy are closely interlinked and interdependent. Energy generation and transmission requires utilization of water resources, particularly for hydroelectric, nuclear, and thermal energy sources. Recent interest in biofuels also creates an incremental demand on water resources; the latest World Water Development Report (2012) predicts that even a nominal increase in biofuel demand (say 5% of road transport by 2030, as predicted by International Energy Agency) could push up the water demand by as much as 20% of the water used for agriculture worldwide. Additionally, biofuel production is linked to increases in water pollution through increased used of fertilizers and agricultural chemicals. Conversely, about 8% of the global energy generation is used for pumping, treating and transporting water to various consumers. Co-production of water and energy, as is the case for geothermal energy generation, offers interesting opportunities to energyand water-scarce countries.


One may, therefore, argue that reflecting the interlinkages between water and energy should be given adequate attention in the new and emerging agenda around the so-called Sustainable Development Goals and the post-2015 development dialogue. This could also be linked to the design of a climate resilient and robust green economy, as noted in the Section III of the Rio+20 outcome document “The Future We Want.” With industries being major water and energy consumers, a green economy will be contingent to the greening of the industrial sector and resource efficient, cleaner production. A particular emphasis has to be placed on increasing the water use efficiency in energy production – essentially producing more kWh per drop of water. This would require a policy environment in which economic and social incentives are offered to promote water use efficiency and protect freshwater ecosystems.
