A drenagem urbana, antes conceituada no rápido escoamento das águas pluviais, tem-se apresentado insustentável no meio urbano. Desse modo, não se trata mais de trabalhar esse sistema isolado, mas sim, integrar todo o sistema das águas urbanas, realizando um manejo eficaz e adequado desde o início do evento de precipitação. A partir disso, algumas alternativas estão sendo desenvolvidas, a fim de compensar os impactos negativos que ocorrem nas áreas urbanas, como alagamentos e inundações.

La experiencia de los Paises Bajos en el manejo del territorio y de las aguas es extensa. Sus habitantes poseen conocimiento acabado de sus características, interactuando dinámicamente con su hábitat. Las necesidades medioambientales y económicas, sin embargo, han obligado a replantarse e incluso revertir este complejo sistema hidráulico.

The Sri Lankan based International Water Management Institute (IWMI) has produced this report assessing the need and effectiveness of agricultural water storage (AWS) in Africa, in the context of climate change risks. Widely anticipated to make a key contribution to climate change adaptation through the mitigation of climate variability, AWS will have to significantly improve if it is to achieve intended benefits.

Studies on the impact of climate change and sea level rise usually rake climate scenarios as their starting point. To support long-term water management planning int he Netherlands, this paper starts at the opposite end of the effect chain. The study refers to three aspects of water management:

flood defence
drinking water supply
protection of the Rotterdam harbour.

This first background paper from the CGIAR Water for Food Program seeks to identify research needs to increase crop water productivity, such that food security can be ensured and farmers’ livelihoods enhanced without increasing water diverted for agriculture.The paper proposes a number of priority topics for research on crop water management in the challenge Program on Water and Food, which will be amended during the development of the Program.

Singapore has been dependent on Malaysia for nearly forty percent of its water supply, and water has been a source of dispute between the two countries. This paper examines the water issues between Singapore and Malaysia.The paper describes the water agreements signed in 1961 and 1962. It discusses some of the important aspects of the dispute between Singapore and Malaysia, including the debate on pricing, the right to revise prices, and the guarantee of supplies after 2061.

Forests play an important role in the water cycle, stimulating rainfall, protecting soils from erosion and regulating the flow of water. It is therefore important to preserve forests for water management. Previous efforts to protect forests in Ecuador have relied on controlling land use and excluding local people. These methods often have limited success, because of problems such as corruption and a lack of enforcement. A new approach is to pay people to protect the forests.

Unstable geological conditions and steep topography, combined with frequent extreme weather conditions, make the Hindu Kush-Himalayan (HKH) region prone to many natural hazards. Among these, flash floods – severe flood events that occur with little warning – are particularly challenging for communities, threatening lives, livelihoods, and infrastructure. Vulnerable groups such as the poor, women, children, the elderly, and people with disabilities are often the hardest hit.

This perspective document: 1 Provides examples of ‘no regrets’ approaches, applied in small island countries to cope with current climate variability and adapt to future climate change, at different levels ranging from communities, local administrations and national governments. 2 Demonstrates the need for a sound knowledge base and information system, as well as a better understanding of the relation between water resources, water and health, and climatic extremes.

This report cautions against an overly rigid approach to the Sustainable Development Goals (SDGs), which it argues could limit development options for poor countries, particularly in how they are able to manage critical water resources. It identifies key challenges such as setting realistic targets, carefully considering the local context to address the needs of the poor, and promoting sustainable water resources development in a way that values healthy ecosystems.

Prepared as part of a study on innovations for irrigation management, this report analyses the history of changes and processes around the de-collectivisation of agriculture in Vietnam in the 1980s.At this time, emerging farming households in the Red River Delta became directly involved in agriculture. New water service requirements arose from de-collectivisation. Former irrigation and drainage management companies (IDMC) lowered their involvement in irrigation activities to the benefit of cooperatives that developed local irrigation capacities.
