Improving integrated management of water resources and their uses in Brazil - INTERAGUAS

This international technical cooperation project is an instrument that aims to leverage the major goals established for the Water Resources Sector, more specifically, to act as support for the implementation of actions included in the components of Water Resources Management and Intersectoral Actions, contained in the Water Sector Development Program – INTERÁGUAS, supported by the Loan Agreement (8074-BR) between the Government of Brazil and the World Bank. It aims to contribute to the development of actions aimed at strengthening the Integrated Management of Water Resources and its multiple uses. In general, its immediate objectives are: (i) Improve the Integrated Management of Water Resources in Brazil; (ii) Strengthen the Interrelationship between Urban Policies and Water Resources; (iii) Develop Actions for the Revitalization of Hydrographic Basins; (iv) Develop Actions to ensure the Management of the INTERÁGUAS Program. This technical cooperation presents an aspect of integration of water resources sectors, incorporating actions aimed at the revitalization of watersheds and urban management in Brazil, which will allow achieving the expected results.

How has IICA integrated NBS into its projects?

The project integrates NBS elements into its Technical Report on available technologies and practices to improve water use efficiency. Among the technologies indicated, Agroforestry Systems and Water Tanks are considered nature-based solutions, as they contribute to the preservation of natural resources while promoting social well-being by enabling agricultural water use and food production.

In addition, another Technical Report from the project presents proposals for the implementation of interventions aimed at revitalizing urban microwatersheds. Among the proposed interventions, the following stand out as NBS: the implementation of Sustainable Hydrological Regime Management with sustainable urban drainage systems, including permeable pavements, rain gardens, and detention reservoirs, as well as the restoration of degraded Permanent Preservation Areas (PPAs). "The revegetation of riverbanks and the restoration of aquifer recharge zones are priority measures to restore the ecological function of microwatersheds and increase water retention capacity. These actions are directly aligned with the strategic guidelines that emphasize the importance of nature-based solutions to promote multiple benefits, including the mitigation of extreme climate events."

Another product of this project that provides nature-based solutions is the Technical Report on Guidelines for Aquifer Recharge Actions, which outlines three types of recharge systems based on natural processes: Box Recharge System, Trench Recharge System, and Channel Recharge System.

 

What lessons learned can you share about collaborating with farmers to implement NBS?

 

Farmers can learn from these experiences about the possibility of using agroforestry systems in their production and installing cisterns to improve water use efficiency. These solutions can be implemented as nature-based solutions if combined with environmental conservation goals.

 

What examples of NBS innovation can you share from your experience at IICA?

Rain gardens, agroforestry systems, cistern installations, and aquifer recharge systems are examples of NBS innovation covered by the technical experiences of this project.

How are you promoting NBS education and training among farmers?

In this project, regarding NBS-related products, only technical reports published in official government media were produced.
