Drainage water and its investment in agriculture in Muqdadiyah city

الملخص

Water scarcity and the deterioration of water resources are among the most prominent challenges facing the agricultural sector in Iraq, particularly in resource-limited areas such as Muqdadiyah District in Diyala Governorate. With the continued decline in water revenues from traditional sources, the need to explore unconventional alternatives has emerged, including agricultural drainage water. This research aims to study the status of drainage water in Muqdadiyah City, in terms of its quantity, quality, and potential impact on agricultural production when reused after treatment or within certain standards. The research also discusses the environmental and economic aspects associated with the reinvestment of this water, with a focus on crops that tolerate high salinity levels and the use of appropriate irrigation methods. Preliminary results indicate the presence of significant quantities of drainage water, but its quality varies depending on the region and drainage source. Some samples show high levels of salts and heavy metals, requiring partial treatment or mixing with fresh water. With the adoption of modern agricultural technologies and rational water management, drainage water can contribute to alleviating the water crisis and achieving relative sustainability for local agriculture in Muqdadiyah.
