Renewable sources of energy are gaining traction worldwide. Solar, wind power, biomass energy and geothermal heat energy are already used in applications in food value chains. Renewable energy can provide energy solutions in situations where there are challenges with traditional energy supplies. Renewable energy also has the capacity to reduce the carbon footprint of food value chains and help mitigate against climate change. Yet, the link between renewable energy and small-scale fisheries and aquaculture is not well documented. This publication introduces the current situation and proposes a way forward with regard to the use of renewable energy in small-scale fisheries. It provides general guidance for decision-makers and development specialists on the choices, benefits and challenges related to renewable energy use and uptake in small-scale fisheries. The publication will contribute to the implementation of the FAO Code of Conduct for Responsible Fisheries (CCRF) and the FAO Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in the Context of Food Security and Poverty Alleviation (SSF Guidelines). FAO’s objectives relate to better production, better nutrition and a better environment.
