The management of water resources in Bangladesh involves a centralised, heavy engineering approach in order to control floods and install irrigation, however, there is now a pressing need for ensuring social justice and equity in water resource development. Recognising the role of water in poverty alleviation, action has been taken to implement a 25-year National Water Management Plan. Although this is one important step, it is evident that many issues require more work.
In Central Asia, water is unevenly distributed with states positioned downstream being placed in a very unfavourable position. The situation is further complicated since the benefits from cooperation are highly asymmetrical. Despite the challenge, the states have taken action and entered into a regional agreement, which attracted the international donor community to engage further. This case illustrates how international initiatives can influence institutional arrangements in transboundary basins.
Unsustainable irrigation policies during the Soviet era have had devastating consequences for the Aral Sea. With the collapse of USSR, the riparian states took action and entered into agreement on Cooperation in the Joint Use and Protection of Water Resources of Interstate Significance. Furthermore, the international community took action and much attention has been devoted to re-establish the Aral Sea ecosystem. This case illustrates the importance of engaging all key stakeholders.
Steadily shrinking for decades due to unsustainable irrigation policies, the Aral Sea is under increasing pressure, making both allocation and availability major challenges. Action has been taken and the Basin Economic Allocation Model has been developed as a long-term decision support system to facilitate putting “value on water use”. This demonstrates that economic models can be applied to assess economic value maximization of different water uses.
In Kyrgyzstan, lack of drinking water and access to sanitation is a pressing problem which reinforces social vulnerability and poverty. Financed by the Asian Development Bank and the World Bank, actions have been taken to improve access to drinking water and sanitation by the Ministry of Health. These projects had a high level of community involvement which increased the sense of ownership.
In Kazakhstan, the issue is not one of scarcity but of management, a problem that can be solved through applying the principles of IWRM. The government of Kazakhstan consequently initiated a water resources management project aiming at strengthening water management organisations and by instituting the practice of IWRM. In this process, training, workshops and dialogues both within and outside the water sector are crucial.
In the village of Parakar, untreated wastewater contaminated agricultural lands, jeopardised food safety and posed severe health risks. In 2010, the Parakar community supported by partners from the Country Water Partnerships of Armenia initiated and developed a demonstration pilot project for domestic wastewater treatment. Particular attention was given to community involvement. This case illustrates the value of small scale solutions.
For many businesses, issues of water scarcity are becoming increasingly relevant to their activities, manifested as increased costs or difficulties to obtain water as users compete for rights. To understand water dependencies in time and space, many companies apply the measure of water footprint, estimating water use throughout the value chain. Using this measure can give important insights into variation between countries in terms of how much of the water relates to production.
To supply water to a growing population, an aqueduct was built in the watershed of El Limón River in Tovar municipality. However, this aqueduct does not provide sufficient supply, creating conflicts among the communities. To solve these, agreements on the use and conservation of water resources have been made among the communities, involving both rural villages and urban areas. This illustrates the benefits of a participatory approach.
In Carabobo State, the urban and agricultural expansions are the main causes of watershed problems resulting from degradation of forests, deforestation and inadequate solid waste management. Since 2009, action has been taken to combat these developments through participatory public policies which focus on environmental education and sustainable development. The key to the success of the project has been extensive capacity building in combination with concrete management tools.
