DocumentOther documentAssessment of irrigation potential in Africa - Arc-Info: a tool for the computation of the irrigation water requirements at continental level
Télédétection et ressources en eau/Remote sensing and water resources p. 115
1995Also available in:
No results found.This article is based on the FAO study “Irrigation potential of Africa: a basin approach” and it is part of the proceedings of the international workshop on “Remote sensing and water resources” (http://www.fao.org/docrep/W7320B/w7320b00.htm) organized by FAO, in collaboration with the Comité interafricain d'études hydrauliques (CIEH), the Laboratoire commun de télédétection Cemagref-Engref (LCT) and Orstom (Institut français de recherche en coopération) and published in 1997. The study FAO undertook in 1995 investigated the potential use of remote sensing and geographic information systems in water resources assessment of small watersheds in semi-arid areas of West Africa. The use of the Arc-Info geographic information system allowed to define the geographical computation units, which are homogeneous regarding average rainfall, potential evapotranspiration, cropping pattern (calendar, intensity) and irrigation efficiency. Combining information on gross irrigation water requirements, area of soils suitable for irrigation and available water resources by basin eventually resulted in an estimation of the physical irrigation potential for Africa.

Book (stand-alone)Technical reportGlobal status of salt-affected soils
Main report
2024Also available in:
No results found.Salt-affected soils, characterized by high soluble salts (saline) or exchangeable sodium (sodic), impact plant growth and occur globally, especially in arid and coastal regions. Salinization stems from natural causes (e.g. climate change, sea level rise) and human actions (e.g. poor irrigation practices, excessive water use). FAO’s Global Map of Salt-Affected Soils reveals that over 1 381 million hectares, 10.7 percent of global land, are affected, with Australia, Argentina and Kazakhstan among the most impacted countries. Increasing aridity and water demand amplify soil degradation risks, particularly in developing regions.Climate change and water scarcity threaten agricultural productivity, with substantial crop yield losses observed in saline areas. Halophytes and salt-tolerant crops provide a foundation for saline agriculture, yet many salt-affected soils remain unprotected and inadequately regulated. FAO’s INSAS (International Network of Salt-Affected Soils) underscores the need for updated data, harmonized salinity measurements, and sustainable management practices, with enhanced training and policy frameworks.Mitigation strategies like improved drainage, soil amendments, and the cultivation of salt-tolerant plants are recommended. Key recommendations include scaling sustainable practices, investing in salt-tolerant crop markets, improving data collection and water quality monitoring, conserving ecosystems, and fostering cross-sector collaboration. Such integrated efforts aim to boost food production and resilience in affected regions while protecting vital ecosystems. -
Book (stand-alone)General interest bookSynergies and trade-offs in climate-smart agriculture
An approach to systematic assessment
2021Also available in:
No results found.This publication analyses of the synergies and trade-offs that can occur within climate-smart agriculture (CSA), more specifically between its three pillars: (i) sustainably increasing productivity and incomes in agriculture, (ii) building resilience of and adapting food and agriculture systems to climate change, (iii) reducing/removing greenhouse gas emissions, where possible. The aim of this analysis is to develop a systematic characterization of possible synergies and trade-offs in CSA, as well as provide a tool to guide CSA practitioners through the assessment of synergies and trade-offs during the design and planning of CSA strategies or interventions. The ultimate objective is to support strategic decisions that enhance synergies and reduce trade-offs to achieve better results for investments in CSA. -
BookletHigh-profileFAO Strategy on Climate Change 2022–2031 2022The FAO Strategy on Climate Change 2022–2031 was endorsed by FAO Council in June 2022. This new strategy replaces the previous strategy from 2017 to better FAO's climate action with the Strategic Framework 2022-2031, and other FAO strategies that have been developed since then. The Strategy was elaborated following an inclusive process of consultation with FAO Members, FAO staff from headquarters and decentralized offices, as well as external partners. It articulates FAO's vision for agrifood systems by 2050, around three main pillars of action: at global and regional level, at country level, and at local level. The Strategy also encourages key guiding principles for action, such as science and innovation, inclusiveness, partnerships, and access to finance.
