The R's (Reduce, Reuse and Recycle) for Climate Resilience Wastewater Systems in Barbados (3R-CReWS)

The R's (Reduce, Reuse and Recycle) for Climate Resilience Wastewater Systems in Barbados (3R-CReWS)

Barbados is facing a climate crisis with an increase in average temperatures, and the number of consecutive hot days. Additionally, annual levels of precipitation are projected to decrease by about nine per cent, extending the dry season by two months. Barbados is experiencing “absolute water scarcity”. Approximately 310 m3 of water is available per person per year, placing Barbados among the most water-scarce countries in the world, and this problem is likely to become worse due to climate change. 

The climate crisis and limited water availability are already impacting food security through the high cost of importation. To counter this, Barbados is seeking to increase food production as an adaptation measure. This project aims to make more water accessible through investment in the circular economy by using carbon neutral and climate-resilient water and energy management technologies that ensure water is protected, managed, recycled, reused, and conserved. The project will contribute to the enhancement of the health, well-being, and productivity of Barbadians.
