Water-Energy-Food for Policymakers: What does it mean?

This briefing by the International Institute for Sustainable Development (IISD) explains the Water-Energy-Food (WEF) nexus, highlighting the need for integrated policy approaches to avoid unintended consequences when managing these three interdependent essentials. It details IISD's efforts to operationalize WEF security through watershed-based management in Canada and stakeholder engagement in Suriname.

• The Water-Energy-Food (WEF) nexus refers to the critical relationships between water, energy, and food security. Traditional approaches to meeting these needs are often unsustainable, leading to issues such as climate change, nutrient loading to waterways, and groundwater depletion. Policies or investments that focus on only one of these three elements often overlook these interconnections, which can lead to serious unintended consequences.
• In the Lake Winnipeg watershed, IISD is implementing a project to improve WEF security by harvesting cattail (Typha). This process provides a sustainable bioenergy source in forms such as ethanol, biochar, syngas, and condensed biomass (bales, cubes, pellets). The harvesting removes 10 to 40 kilograms of phosphorus per hectare, which helps reduce algal blooms in Lake Winnipeg; this phosphorus can then be recovered from ash to be used as agricultural fertilizer.
• In Suriname, IISD is applying WEF principles to mining development by using collaborative and analytical approaches to help residents understand development impacts. The project emphasizes that WEF monitoring requires two types of indicators: outcome-based indicators, which measure socio-economic and physical changes like energy sources and water quality, and process-based indicators, which track the integration of actions, such as the level of stakeholder involvement in decision-making.
