A Guide to Monitoring and EvaluatingWater Funds

This guides exposes how to sustain an  existing water funds, how  to encourage new ones and the need of  implementating a monitoring and impact evaluations. Implementation monitoring maximizesthe chanceof a water fund being successful because it allows for adaptive management, and an impact evaluationgeneratesevidence of benefits to people and nature and highlights what works.

New knowledge resource: A Guide to Monitoring and Evaluating Water Funds
TNC recently developed a new guidance doc to support water fund project managers and field staff. Available in EnglishSpanish and Portuguese, it provides practical guidance and advice on the design and implementation of monitoring for any water fund. If our "science-based" adage is to be more than marketing speak, then sustainably-funded monitoring needs to be a part of every water fund.

Opportunities to improve urban water security in Latin America with natural infrastructure

Natural Infrastructure for Water of the Guandu System, Rio de Janeiro

This report is part of a series of knowledge products of the World Resource Institute
(WRI), in which the WRI Green-Gray Assessment is applied to evaluate new solutions to the challenges of water management in Latin America. In the Rio de Janeiro Report, the study shows that the restoration of 3,000 hectares would result in a 13% return on investment for Rio´s State Water and Sewage Company (CEDAE), generating approximately $39 million in savings for the company over a period of 30 years.

Forest and Water on a Changing Planet: Vulnerability, Adaptation and Governance Opportunities

The current report reflects the importance of integrated action towards ensuring access to water for all and sustaining life on land. The provision of clean water is the most basic ecosystem service necessary for life on earth. Yet, growing demand for water caused by an increasing human population, combined with adverse effects of climate change, are creating unprecedented challenges for sustainable development.

Natural Infrastructure in São Paulo’s Water System

This report is part of a series of informational products of the Institute of World Resources (WRI), in which the WRI Green-Gray Assessment is applied to evaluate new solutions to water management challenges in Latin America. A key concept is that natural infrastructure must be considered a strategy for water management in Brazil, in Latin America, and around the world.

The São Paulo Report shows that the restoration of 4,000 hectares and the maintenance of the original vegetation can reduce soil erosion over a period of 30 years, which would diminish by 36% the displacement of soil, dirt, and sediments in the rivers that supply the Cantareira system, generating a total net savings of approximately $69 million.

A proactive approach to water management in Peru
The Peruvian government has carried out strategic water management actions and ecosystem services that contribute to sustainable development and the creation of ever greater human and institutional capacities.

Variabilidad y Cambio Climático en Guatemala - FUNCAGUA
February 2018
This study presents the conditions related to the subject over time and that could occur in the different climatic regions of the country, so that the information is an essential input for the definition, formulation, planning, and execution of projects for the reduction of vulnerability, of mitigation, and adaptation to the variability and climate change in Guatemala.

Beyond the Source - TNC
Healthy watersheds are vital natural infrastructure for cities around the world as they capture, store, and filter water. They also provide benefits for the conservation of biodiversity, adaptation, and mitigation against climate change and human health and well-being. However, 40% of areas around river watersheds show significant levels of degradation. Protecting and restoring the natural infrastructure of the watersheds can directly improve the quality and amount of water available.

The biodiversity of fish and its conservation in South America
The global demand for food, energy and housing generates unprecedented pressure on our water resources. As this happens, the protection of water sources becomes vital.

Sub-Saharan Africa's Urban Water Blueprint - TNC
This report investigates the status of urban water sources in Sub-Saharan Africa and its potential for watershed protection for the benefit of cities, rural livelihoods and nature. Protecting areas of water production is a brilliant investment opportunity for governments, civil society, and business leaders.

China Urban Water Blueprint - TNC
China is experiencing the full force of water security challenges. At least one-third of its rivers and lakes are highly polluted for human use, and 73% of the watersheds that supply water to fast-growing cities face high levels of pollution. TNC has dedicated itself to studying the state of water around the world and decided to deepen its work in China given the challenges and the importance of the country for the global economy, the environment, and human development.

Green infrastructure in the drinking water sector in Latin America and the Caribbean: Trends, challenges and opportunities
For many years in Latin America and the Caribbean the solutions to the deterioration or insufficiency of water resources in watersheds, whether due to pollution, waste, natural disasters, growth of cities, among other causes, were investments in construction of gray infrastructure works. However, the trend today is to invest in green infrastructure.
