Description
Globally, irrigated agriculture consumes 70% of fresh water resources and provides 40% of global food requirements. Increase in agricultural production and productivity depends, to a large extent, on the availability of water which is drawn either from river diversions (canal irrigation) or from aquifers (groundwater irrigation). Groundwater resources are often the only source of reliable clean water in many parts of the world. In most of the cases, good quality aquifers are exploited for irrigation at rates higher than natural replenishment rates leading to decline in groundwater levels. Therefore a more precise knowledge of sources of water and estimates of recharge rates, and groundwater dating to know how fast the aquifer is replenished are important aspects to assess future availability and sustainability of these resources. This CRP aims to improve capability and expertise among Member States in the use of environmental isotope techniques for better assessment and mapping of water sources for improved irrigation practices and sustainable water management in irrigated areas.
Objectives
Overall objective of the CRP is to test and develop capabilities and new methodologies in Member States in the assessment, mapping and better management of groundwater resources used for irrigation purposes. ?
Specific objectives
To develop best-practice guidelines on integrating environmental isotopes and other indicators for sustainable management of water resources in irrigated areas.
To improve the assessment of groundwater resources used for irrigation purposes for the adoption of medium-term plans aiming at the sustainable use of groundwater resources for irrigation.
To develop and test methods and approaches based on the use environmental isotopes for identifying and mapping groundwater sources used for irrigation purposes at local/regional scales.

Impact
The impact of the CRP has been substantial and far-reaching. Through the utilization of cutting-edge isotope techniques, the project has significantly enhanced our understanding of water sources within irrigation systems and their implications for agricultural sustainability. By employing isotope and hydrogeochemical techniques, the project has facilitated more accurate assessments of water quality and availability in irrigation systems. This has led to more efficient water management practices and enhancing overall water use efficiency. The project has contributed to the advancement of scientific knowledge in the field of water resource management and using isotope techniques. Research conducted as part of the project has led to the development of new methodologies and approaches that can be applied in similar contexts worldwide. The project also has positive environmental impacts by promoting sustainable water usage practices. By optimizing water use in irrigation systems, the project will help to mitigate the depletion of water resources and reduce the environmental impact associated with excessive water extraction. Insights from the project have been integrated into policy frameworks aimed at promoting sustainable water use and agricultural development, thereby influencing decision-making processes at various levels. The project had a significant impact on water resources management, agricultural productivity, knowledge dissemination, policy development, and scientific advancement. Its contributions extend beyond the duration of the project, leaving a legacy in the field of irrigation system evaluation and water resources management. Overall, the CRP resulted in having more experienced participating Member States in the application of environmental isotopes for the assessment of water sources to improve the irrigation practices and increase water and food security, as well as for a better understanding of remediation strategies and management of water resources in irrigated areas.
Relevance
The project has been highly relevant to the needs and priorities of stakeholders involved in water resource management and agricultural development. The project addressed a critical need for improved water management strategies in irrigation systems. With growing concerns over water scarcity and the sustainability of agricultural practices, there was a clear demand for innovative approaches to assess and manage water resources effectively. The project leveraged state-of-the-art isotope techniques, reflecting the latest advancements in scientific research and technology. This ensured that the project's methodologies were at the forefront of innovation and could provide valuable insights into water sources in irrigation systems. The project's focus on improving water management in irrigation systems directly contributed to several Sustainable Development Goals (SDGs), including SDG 2 (Zero Hunger), and SDG 6 (Clean Water and Sanitation). By addressing these interconnected goals, the project demonstrated its relevance to broader development agendas. The project's findings and methodologies have the potential for scalability and replicability in different geographical contexts and irrigation systems worldwide. This underlines its relevance not only at the local level but also within the broader global context of water resource management. The project demonstrated high relevance by addressing critical needs, aligning with national priorities, leveraging advanced techniques, engaging stakeholders, offering scalability and replicability, and contributing to sustainable development objectives. Its relevance ensured that it made meaningful contributions to addressing challenges in water resource management and agricultural sustainability.
