Brochure, flyer, fact-sheetBrochureTravaux de la FAO concernant les forêts pour la sécurité alimentaire, la nutrition, la santé et le bien-être 2021Le programme du Département des forêts de la FAO en faveur de la sécurité alimentaire et de la nutrition, en phase avec le concept «Une seule santé», incite les communautés mondiales et régionales et les gouvernements nationaux à se focaliser sur le potentiel à long terme des forêts, lesquelles sont aptes à procurer des bénéfices durables en termes de sécurité alimentaire, de nutrition et de santé humaine, plutôt que de se concentrer sur des considérations économiques à court terme.

Book (series)Technical studyAgriculture 4.0 – Agricultural robotics and automated equipment for sustainable crop production 2020This report presents and reflects on the opportunities that new technological developments related to automation and precision agriculture (e.g. robotics) can offer to agriculture in developing countries. These technologies are mainly targeted to support farmers that struggle with the cost of labour when harvesting crops and to tackle the declining availability of manpower for general cropping operations. This report also explores the possible applications of agricultural technology, presents the current trends and discusses some of the principle challenges to successful adoption for sustainable agricultural mechanization in developing countries.

Book (stand-alone)Technical studyDeep-ocean climate change impacts on habitat, fish and fisheries
FAO Fisheries and Aquaculture Technical Paper No. 638
2019Also available in:
No results found.This publication presents the outcome of a meeting between the FAO/UNEP ABNJ Deep-seas and Biodiversity project and the Deep Ocean Stewardship Initiative. It focuses on the impacts of climatic changes on demersal fisheries, and the interactions of these fisheries with other species and vulnerable marine ecosystems. Regional fisheries management organizations rely on scientific information to develop advice to managers. In recent decades, climate change has been a focus largely as a unidirectional forcing over decadal timescales. However, changes can occur abruptly when critical thresholds are crossed. Moreover, distribution changes are expected as populations shift from existing to new areas. Hence, there is a need for new monitoring programmes to help scientists understand how these changes affect productivity and biodiversity. The principal cause of climate change is rising greenhouse gases and other compounds in the atmosphere that trap heat causing global warming, leading to deoxygenation and acidification in the oceans. Three-dimensional fully coupled earth system models are used to predict the extent of these changes in the deep oceans at 200–2500 m depth. Trends in changes are identified in many variables, including temperature, pH, oxygen and supply of particulate organic carbon (POC). Regional differences are identified, indicating the complexity of the predictions. The response of various fish and invertebrate species to these changes in the physical environment are analysed using hazard and suitability modelling. Predictions are made to changes in distributions of commercial species, though in practice the processes governing population abundance are poorly understood in the deep-sea environment, and predicted
