water Management
1. Wastewater treatment: A critical component of a circular economy
water is extracted from the source, treated, and used; the wastewater is then treated and discharged in a receiving water body. But, we need to transition from the linear model to a circular one focused on reducing water use and consumption and promoting reuse, recycling, restoration, and recovery of water resources.
2. Thirsty Energy: A five-year journey to address water-energy nexus challenges
Significant amounts of water are needed in almost all energy generation processes, from generating hydropower, to cooling (and other purposes) in thermal power plants, to extracting and processing fuels. Conversely, the water sector needs energy to extract, treat, and transport water.
The World Bank-supported Flood Risk Management Support Project for the City of Buenos Aires is working on helping 1.7 million people commute to work, and access schools and medical facilities, by reducing the impact from rain.
4. A low-priced water reuse process that also delivers renewable energy in rural areas
Anaerobic Digestion (AD) systems are installed for many different purposes, such as a waste treatment step, a means to reduce odour’s, a source of additional revenues, or a way to improve public image.
5. Solar Pumping 101: the what, why, and the how
In many communities, groundwater is being pumped by diesel fuelled systems, which are both expensive and difficult to maintain. But fortunately, solar power offers a more cost-effective and environment-friendly alternative solution, especially for the communities where electricity is scarce. The highest demand for solar pumps is among rural off-grid areas, currently underserved, or served by costly fuel-driven pumps. Solar pumping is most competitive in regions with high solar insolation,
6. China’s experience in tackling water scarcity through sustainable agricultural water management
Water scarcity is a pervasive problem across much of China. By the numbers, per capita water resources stand at only 2,100 cubic meters, which is one-fourth of the global average. Population growth, agricultural demands, and the adverse impacts of climate change further compound the challenge.
7. How many people can share a toilet?
In urban areas, almost one person in ten uses a shared household toilet, i.e., a toilet shared with at least one neighbouring household.
While individual household sanitation is both crucial and aspirational, it will be insufficient to meet the needs of growing urban populations in the coming years.
8. Time to adapt to changing climate: what does it mean for water?
Recognizing that millions of people across the world are already facing the severe consequences of more extreme weather events, the World Bank Group announced a major new set of climate targets for 2021-2025 at COP24, which significantly boosts support for adaptation and resilience.
