    Reducing Water Pollution from Agrochemicals in Litani River and Qaraoun Lake, Governorate of Bekaa - UTF/LEB/028/LEB 2023
    Also available in:
    No results found.

    Water pollution in the LitaniRiver and Lake Qaraoun, in the Governorate of Bekaa, poses a serious problem for human health and the environment. The source of pollution, originating from the agricultural sector, is mainly due to the excessive and indiscriminate use of fertilizers and pesticides by farmers. In particular, the runoff from agriculture contributes to poor water quality, as farmers do not employ good agricultural practices (GAP) for preserving natural resources in soil or irrigation water management, pest and crop management, and often overuse agrochemical applications. Against this background, the main objective of the project was to reduce underground, LitaniRiver and Lake Qaraounwater pollution through the promotion and application of GAP, including integrated pest management (IPM), by farmers in the Upper LitaniRiver Basin and Lake Qaraoun.

    Arsenic contamination of irrigation water, soil and crops in Bangladesh: risk implications for sustainable agriculture and food safety in Asia 2006

    Arsenic in groundwater is a major health concern in Asia and the risks from using shallow tubewells for drinking-water are well known. At present, 12 countries in the region have reported high arsenic levels in parts of their groundwater and recent studies have documented the potential risks from arsenic in irrigation water. The most well known concern is arsenic contamination entering the food chain, affecting food safety. This poses a potential dietary risk to human health in addition to the r isk from drinking contaminated groundwater. Less well known but potentially more serious is the risk to crop production. Continuous build up of arsenic in the soil from arsenic contaminated irrigation water may reduce crop yields, thus affecting the nutritional status and incomes of rural farming communities. As part of the green revolution, millions of shallow tubewells were installed throughout Asia over the last three decades. This resulted in a sharp increase of groundwater extraction for ir rigation. Considering the high number of arsenic contaminated tubewells, the amount of contaminated irrigation water entering the soil and its effects on crop yields and toxity to plants as well as to livestock and freshwater fisheries are of urgent concern. This must-read technical report for those involved with the issue of arsenic in irrigation water examines the available knowledge to date, focusing on Bangladesh where most studies on arsenic contaminated irrigation water have been carried o ut. Specific attention is given to rice owing to its importance in Asia and because it is one of the crops most sensitive to arsenic contamination. The report identifies knowledge gaps, the risks to food safety and crop production and the possible threat to sustainable development in the region. The author provides recommendations to key stakeholders concerned and advocates an integrated regional programme covering both crop production and food safety aspects within the framework of land degrada tion. Most importantly, the scale of the problem needs to be quantified and appropriate management options developed and disseminated.

    More people, more food… worse water? - Water Pollution from Agriculture: a global review 2018
    Also available in:

    Current patterns of agricultural expansion and intensification are bringing unprecedented environmental externalities, including impacts on water quality. While water pollution is slowly starting to receive the attention it deserves, the contribution of agriculture to this problem has not yet received sufficient consideration. We need a much better understanding of the causes and effects of agricultural water pollution as well as effective means to prevent and remedy the problem. In the existing literature, information on water pollution from agriculture is highly dispersed. This repost is a comprehensive review and covers different agricultural sectors (including crops, livestock and aquaculture), and examines the drivers of water pollution in these sectors as well as the resulting pressures and changes in water bodies, the associated impacts on human health and the environment, and the responses needed to prevent pollution and mitigate its risks.
