Peru: Local Financing of Water Utilities; Challenges and opportunities (#402)

The legal and regulatory framework of water utilities in Peru provides opportunities for local financing of investments. Despite this, the sector remains heavily dependent on public financing. Action has been taken by the World Bank to initiate a study investigating the barriers to local private funding. This case study illustrates that public loans, private loans and equity investment are appropriate to fund the necessary investment. 

Peru: Treated waters - communal participatory management and its impact on human development and ecosystem (#436)

The lowland valley of Chancay-Lambayeque watershed is scarce of water resources, forcing farmers to irrigate with insufficiently treated waste water, resulting in severe health issues. Action was taken through the project “Future Development of San José farmer community: Wastewater” which was a collaboration between the private and the public sectors, aiming to illustrate alternative ways to irrigate. The most important lesson is that cooperation is an important instrument for development.  

The Bahamas: The IWRM Planning Process in the Bahamas (#414)

The water resources of The Bahamas are threatened by over-abstraction, misuse and pollution. In the past, water management in the Bahamas has been conducted through a single-sector approach. To address its issues, actions have been taken to move towards IWRM and a multi-sector approach. In particular, attention has been focused on improving stakeholder participation and advancing political commitment. Presently only being partially successful, IWRM implementation in Bahamas highlights that it is a long term process. 

Transboundary: Groundwater management issues for Guarani aquifer (# 368)

The quality of groundwater recharging the Guarani aquifer is threatened in some areas by rapid land-use changes, and locally by rapid urbanisation. Action was taken by the World Bank through a GEF-funded project on the ‘Sustainable Development & Environmental Protection of the Guarani Aquifer’, which included scientific studies, institutional provisions and transboundary groundwater management. This case study reinforces the lesson to ‘think globally but act locally’. 

Transboundary: Oppportunities and Challenges for the Shared Management of Watersheds; the Trifino Plan for the Upper Lempa (#394)

The Lempa River is shared by Guatemala, El Salvador and Honduras, making its management a good example of transboundary cooperation. To reach consensus, action was taken to develop a treaty as part of a regional process.  However, since the treaty was not accompanied by strategies designed by local actors, it is somewhat weak. Nonetheless, this case illustrates that political willingness is crucial for advancing towards IWRM in transboundary watersheds. 

Transboundary: Trans-border management group for the conservation of the environment of the Goascoran River, Honduras and El Salvador (#320)

The Goascoran River basin is shared by Honduras and El Salvador and is of great environmental, economical and geopolitical importance. In 2006, action was taken to create a multi-sector instance to integrate, influence and coordinate sustainable management of the shared basin. This experience is of great value for IWRM, as the management group establishes a model of work for transboundary management.

Transboundary: Water Governance and Implementation of IWRM through Local Community Action in the Tacaná Watersheds; Guatemala & Mexico (#424)

Wathersheds of Tacana originate on the volcano, with both shared by Guatemala and Mexico. This region is of great strategic importance for both countries since they supply water to a large number of residents in the cities located downstream and are the main source of irrigation water for agriculture. In the lower reaches, fishing is an important source of income.

Trinidad and Tobago: Towards adaptive IWRM in Matura basin (#461)

The Matura watershed is located in the eastern region of Trinidad. The major threats to watershed degradation originate from anthropogenic activities that are unsustainably executed. Several mitigation measures were initiated by the regulatory agencies that constantly monitor the watershed as well as the community-based organisation, Nature Seekers.

Uruguay: Capacity building for climate disaster risk management at local level in Pantanoso watershed in Montevideo (#439)

The Pantanoso watershed in Montevideo has been identified as vulnerable to threats of intense rains and floods, posing risks to the human settlements. To combat the risks, action was taken by the local population and governmental authorities to engage in a project on Climate Related Disaster Risk Management. The key lesson is that strengthening vulnerable communities upon climate risks represents a key tool for the IWRM, since it contributes to empowering the population.
