Pakistan Implements New Sustainable Agriculture Concept for Arid Regions

Pakistan is considering an innovative concept that involves the integration of water supply, energy, and food production systems. This approach has the potential to ensure the resilience of the country’s agro-industrial complex, especially in the context of acute water resource shortages. The main goal of this strategy is to reduce dependence on resource-intensive technologies and guarantee food security with minimal environmental impact.

WEF Nexus Research: New Pathways for the Agricultural Sector

An unconventional approach known as the WEF Nexus (Water-Energy-Food Nexus) was presented in a study published in the journal Agricultural Systems. This is the first quantitative model that offers comprehensive management of water, energy, and food systems for transitioning to sustainable agriculture. The research group was led by Professor Chen Yaning from the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences. According to the researchers, the developed model can be applied not only in Pakistan but also in many other semi-arid regions of the world. The key question they seek to answer is how to increase agricultural sector productivity amid the depletion of natural resources.

Data analysis covering the period from 1991 to 2021, which included indicators of agriculture, hydrology, and energy, revealed a significant disproportion between resource consumption and final outcomes. The agricultural sector in Pakistan uses nearly 90% of all available freshwater, while wheat yields remain at only half of the global average. Projections for 2031 indicate that to increase productivity by 15.1%, pesticide use will need to increase by 82.25%, fertilizers by 19%, and cultivated area by 5.42%. However, this will lead to further reductions in water (by 4.22%) and energy (by 6.15%) reserves.

Innovations to Enhance Agricultural Production Efficiency

Such trends underscore the relevance of moving away from traditional resource-intensive approaches. The WEF Nexus concept involves optimizing water use, developing renewable energy sources in the agricultural sector, rational application of agrochemicals, and strengthening inter-agency coordination.

“Strategies focused solely on expanding areas or increasing chemical use are no longer viable,” emphasized Hasan Iqbal, the lead author of the study.

Among the practical solutions proposed by the researchers are the implementation of drip irrigation systems capable of reducing water consumption by 15–20%, transitioning to solar energy to lower energy costs, and integrated pest management, which allows for a reduction in chemical use by up to 40%. The authors emphasize that in the face of climate challenges and increasing pressure on natural resources, comprehensive solutions are critically important for water-scarce countries. In Pakistan, the proposed model could be implemented in the coming years, opening new opportunities for the sustainable development of the agricultural sector.
