The Ziquejie Terrace is one of the three famous Chinese ancient terraces in Hunan Province. The crops cultivated in the terraces can manage to thrive through drought and flood without reservoir or other water storage constructions. This traditional primitive gravity irrigation system is a model for ecological construction of irrigation systems. However, the mechanism of Gravity Irrigation and water allocation within Ziquejie Terrace has not been well revealed, which to large extent affects the efficiency of environmental and ecological protection for this extraordinary natural reserve.

The cattle corridor of Uganda has semi-arid characteristics, high variability of rainfall and droughts. The main economic activities in this area are pastoralism and crop production. Historically, the area has been well known for reliance on mobile pastoralism as an important strategy to cope with resource variability. However, people’s abilities to cope greatly weakened as the impacts of disasters became frequent and severe. The recurrence of droughts in the Aswa-Agago Sub-Catchment has been exacerbated by climate change. This has compromised the ability of populations and ecosystems in the area to recover from the shocks. 

Lake Cyohoha and its 508 km² watershed in the Bugesera region marks the border between Southern Rwanda and Northern Burundi. In the GWP WACDEP climate resilience project, stakeholders analyzed the situation and decided for actions. Drought resistant trees were planted, water points installed and connected to a supply network, fuel saving stoves and biogas was introduced and capacity development events were held. 

The Water, Climate and Development Programme (WACDEP) is an initiative of The African Union (AU) Heads of States and Governments borne out of a declaration to improve water and human security. It is a three year programme being implemented in 8 African countries and 5 river basins including the White Volta Basin in Ghana. The project aims to promote water security and climate resilience development as a key component of socio-economic transformation of the people by strengthening decision making processes while ensuring coherence at all levels. As part of the project implementation process, a Field demonstration project is being implemented in the Upper East Region in the White Volta Basin.

Le Programme eau, climat et développement (WACDEP) est une initiative des chefs d'État et de gouvernement de l'Union africaine (UA) issue d'une déclaration visant à améliorer l'eau et la sécurité humaine. Il s'agit d'un programme de trois ans mis en œuvre dans 8 pays africains et 5 bassins hydrographiques, dont le bassin de la Volta blanche au Ghana. Le projet vise à promouvoir la sécurité en eau et le développement résilient au climat comme un élément clé de la transformation socio-économique des populations en renforçant les processus décisionnels tout en assurant la cohérence à tous les niveaux. Dans le cadre du processus de mise en œuvre du programme, un projet de démonstration sur le terrain est en cours d'exécution dans la région de l'Upper East, dans le bassin de la Volta blanche. Le projet de démonstration vise à encourager l'innovation dans la mise en œuvre d'investissements sans/ à faible regret en employant des stratégies de sécurité de l'eau et de résistance au changement climatique d'une part et d’autre part en soutenant l'intégration de ces investissements dans la planification du développement et les processus décisionnels dans les districts. Cet objectif principal sera atteint grâce à quatre (4) objectifs stratégiques notamment Établir les tendances actuelles des impacts du changement climatique; Créer des voies pour des «solutions vertes novatrices» et des interventions adaptées au climat; Soutenir le processus de prise de décision concernant la mise en œuvre d'investissements sans/ à faible regret pour garantir la pérennité des moyens de subsistance et renforcer la résilience dans les domaines de l'eau, des ressources alimentaires et énergétiques contre la menace croissante du changement climatique et estimer le rendement de ces investissements verts sans /à faible regret.

Flood damage is caused by excessive precipitation and is exacerbated by actions that place people and property in watercourses. It accounts for more l

The increasing degradation of the Reventazon River Basin, mainly through water pollution, was the reason for the establishment of the Committee for the Management and Planning of the Reventazon River Basin (COMCURE), who takes measures in its control and protection. The contamination of water promotes the proliferation of waterborne diseases, reduces the number of available water sources, raises the costs for supplying drinking water and is a threat to many species of flora and fauna.

The Municipality of Talcahuano, due to its geographic location, natural conditions and closeness to energy supply centres, such as coal from Lota and Coronel, had from the 50´s an important economic growth, a greater military presence, and an increased port capacity; all this led to an accelerated urban growth. The co-existence of active urban and industrial areas in an uneven territory, with abundant water bodies and a surface area of only 142.8 km2, have made the city specially sensitive to natural resource degradation. A situation was made critical and gave rise to the municipal strategy started in 1993. This situation was being aggravated by the chronic scarcity of resources in the Municipality and the lack of infrastructure and control mechanisms faced with environmental deterioration. The Municipality, as the institution in charge of administering this serious environmental deterioration that affected the quality of life of its inhabitants, in co-ordination with other public, private and community organisations, manifest their outmost commitment and concern for decreasing water contamination. A program to appropriately zone the city in order to harmonise the different activities was implemented. The Spanish version.

The Segura Basin in Spain is the driest in Europe. With 365 mm of annual rainfall, this basin has the lowest rainfall in the European Union. Nevertheless, it is also a region which exports fruit and vegetables. The Segura River is thus the main water sources for irrigation. In 1986, when Spain became a member of the European Union, the production of agriculture and canned food significantly increased. As a consequence, a rise in wastewater discharges and lack of water in the already water-stressed Segura River brought extreme deterioration of the water-related ecosystem and a strong social discontent.

The Graeme Hall Swamp is linked to the St. Lawrence Lagoon and is the last remaining coastal wetland in Barbados. The wetland has been designated as a Natural Heritage Conservation Area and has also been established as one of two Caribbean Coastal Marine Productivity Programme (CARICOMP) monitoring sites in Barbados. The Graeme Hall Watershed, located in the south of Barbados, spans 1,156 acres. The most significant element of this watershed is the Graeme Hall Swamp.
