Synopsis (short abstract) The purpose of this study is to provide an updated and comprehensive database of information on the status and progresses made on the use of treated wastewater in Lebanon, to highlight data gaps and inconsistencies, and assess the potentialities of TWW using a case study approach in Caza (Province) through a GIS multilayer analysis. The study is based on the work of the FAO project 'Coping with water scarcity - the role of agriculture – Phase III', active in Lebanon since 2011, which seeks to st rengthen the safe use of treated wastewater in agriculture and deals with the agricultural component of water scarcity. The study also presents a tool to support the Government of Lebanon to meet its stated objectives for agricultural water management and to develop new policies on the use of TWW. It will further contribute to the achievement of a number of existing national strategies relating to water, agriculture, environmental management and desertification.

    Monitoring treated wastewater in the United Arab Emirates - GCP/UAE/001/AFC 2018
    Also available in:
    A major challenge faced by the United Arab Emirates is the sustainability of their natural resources, above all water. Traditionally, water demands have been met through the exploitation of groundwater. However, rapid economic development, coupled with an increased population, has significantly increased water demand. Groundwater abstraction in Abu Dhabi is currently over 25 times the average recharge rate and groundwater resources are expected to be exhausted within the next 50 years. To reduce its reliance on groundwater and desalinated water, the Emirate plans to increase the use of TWW for agriculture. The main challenge is how to do this without endangering citizens’ health or the environment. In response to this challenge, the project strengthened the capabilities of Abu Dhabi Food Control Authority ADFCA in the safe reuse of TWW for agriculture through the improved monitoring of treated sewage effluent.

    Unlocking the Potential of Treated Wastewater and Drainage Water Use for Agricultural Development in North Africa - TCP/SNE/3701 2022
    Also available in:
    Concerns over water scarcity and severe water supply shortages are driving governments to find alternative solutions, including the development of non conventional water resources In this context, the application of non conventional waters ( has the potential to help countries meet increasing water demands, particularly during years of drought Moreover, through proper planning and management, NCW reuse schemes offer economic and environmental benefits In Maghreb countries, both treated wastewater ( and drainage water ( present opportunities for the development of NCW systems Notably, the total volume of wastewater produced in Algeria, Libya, Mauritania, Morocco and Tunisia amounts to 2 33 billion cubic metres per year (FAO AQUASTAT) However, only half of the wastewater produced in the Near East and North Africa region is collected While the international community recognizes that the application of TWW can serve as an important resource for agriculture, much work is still needed to advance national policies on the matter, as well as to implement relevant safe use guidelines and practices This project was designed to support Maghreb countries with information and technical knowledge for developing TWW and DW into promising alternative sources of irrigation water This was achieved through the adoption of a holistic regional approach, by addressing technology gaps, and by ensuring the economic feasibility of interventions.
