Brochure, flyer, fact-sheetBrochureGlobal Forest Resources Assessment 2020
Key findings
2020This publication contains the main findings of the Global Forest Resources Assessment 2020 (FRA 2020). The data in FRA 2020 have been obtained through a transparent, traceable, reporting process and a well- established network of officially nominated national correspondents. The information provided by FRA presents a comprehensive picture of the world's forests and the ways the resource is changing. Such a clear global picture supports the development of sound policies, practices and investements affecting forests and forestry. -
Book (series)Technical studySmall-scale aquaponic food production – Integrated fish and plant farming 2014This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourci ng for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations fo r establishing aquaponic units; a cost–benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.

Book (stand-alone)Technical bookHome-Grown School Feeding Resource Framework
Technical Document
2018Also available in:
This Resource framework is intended as a guidance tool for stakeholders involved in programme design, implementation and monitoring of Home-Grown School Feeding Programmes and the related policy and institutional environment, including, inter alia: governments and development partners providing technical and financial assistance, as well as civil society, community based organisations and the private sector. It is a knowledge product that harmonizes the existing approaches and tools, and builds on the wealth of expertise and experience with home grown school feeding models i.e. those designed to provide children in schools with safe, diverse and nutritious food, sourced locally from smallholders, with multiple impacts on Sustainable Development Goals. This knowledge product contains a discussion of concepts, issues and experience , as well as other considerations and elements of relevance to home grown school feeding programmes. This lays the ground for a community of practice to support innovation and learning, as well as replication, adaptation and expansion of successful models of interventions, for impact at scale.This publication is the result of a broad based collaborative effort initiated and coordinated by the World Food Programme. It is authored by a team composed of experts from Rome-based Agencies including the Food and Agriculture Organization of the United Nations, the International Fund for Agricultural Development and the World Food Programme and from other partners including the Global Child Nutrition Foundation, the Partnership for Child Development, the New Partnership for Africa’s Development and the World Food Programme Centre of Excellence in Brazil. It has benefited from comprehensive reviews and wide consultations among the partner organizations at global, regional and country level, as well as with experts and members of various governments and relevant stakeholders at several relevant venues for learning and policy dialogue.
