Book excerpt: The Addressing Fisheries and Aquaculture in National Adaptation Plans Supplement provides technical guidance on the integration of fisheries and aquaculture in the formulation and implementation of National Adaptation Plans (NAPs) and complements FAO’s Addressing agriculture, forestry and fisheries in National Adaptation Plans – Supplementary guidelines (referred to as NAP-Ag Guidelines, FAO 2017a). It aims to draw the attention of policy makers and government officers responsible for NAP planning and processes generally, as well as fisheries and aquaculture officers at country level, specifically. It collates and analyses relevant information from fisheries and aquaculture to support the sector’s ability to take part in national climate change adaptation planning processes.
