    While population growth and economic development are putting unprecedented pressure on renewable, but finite water resources, especially in arid regions, scarce land and water resources are affecting food security and sustainable water management. FAO identified the need to implement a digital database built upon remote sensing and information technologies that can monitor and report on agricultural water productivity over Africa and Near East, accessible through the FAO Water Productivity through Open access of Remotely sensed derived data portal (WaPOR). The WaPOR database is now operational at continental level (all African and Near East countries covered by the 250 m spatial resolution data), national level (two beneficiary countries can access the WaPOR database at 100 m resolution) and subnational level with a spatial resolution of about 30 m, so far including eight areas of interest (river basins or irrigation schemes). Water Accounting Plus (WA+) reports based on remote sensing have been completed for three river basins as planned (Litani in Lebanon, Awash in Ethiopia and Jordan basin). An action framework at national level for capacity building and participatory decision making is currently being developed to make effective a “demand-driven” approach based on national and local needs.

    Given the scarcity of land and water resources, global strategies to increase food production should focus efforts on increasing production per unit resources, i.e. the combined increase of production per unit land surface (yield expressed in kg/ha) and the increase of production per unit water used (water productivity expressed in kg/m³). The FAO portal to monitor WAter Productivity through Open access of Remotely sensed derived data (WaPOR) uses satellite information to compute and map key variables related to water and agriculture, such as evapotranspiration, biomass production and water productivity. The provision of near real time information through such open access data portal enables a range of service-providers to assist farmers attain more reliable yields and to improve their livelihoods; irrigation operators have access to new information to assess the performance of systems and to identify where to focus investments to modernize the irrigation schemes; and government agencies will be able to use the information to monitor and promote the efficient use of natural resources. This report presents the work undertaken to identify key stakeholders in the agriculture and Information and Communication Technologies (ICT) sector and the capacity needs of farmers to improve water productivity in a sustainable manner, through two components; the first surveys the role and capacities of various stakeholders in the ICT and agriculture sector in Lebanon, and the second presents and analyzes the results of a survey into the capacity needs of farmers in relation to the use of ICT in agriculture in the Bekaa valley.

    Seasonal mapping of crop types and water use in Northern Gaza Strip: insights from remote sensing and field surveys (2021–2023) 2024
    Also available in:
    No results found.

    This study focuses on assessing crop productivity and water use efficiency in the northern region of Gaza through remote sensing and field measurements. It aims to accurately map and identify crop types in the study areas using remote sensing data, including satellite imagery and in situ measurements. The objective of this study is to conduct crop type mapping and water consumption mapping based on evapotranspiration (ET). Calculating evapotranspiration alone does not give definitive indicators, because it does not calculate leaching requirements of crops, nor does it calculate the efficiency of irrigation systems using remote sensing techniques. The study covers the period from 2021 to 2023 and focuses on the summer and winter seasons in East Gaza city (Al-Shujaia), Beit Hanoun and East Jabalia North Gaza.
