To be clear, nexus projects do exist that have put principle to practice with impressive results. In Central Asia, for example, research by the International Water Management Institute (IWMI) demonstrates that substantial savings can be achieved in water and energy if more efficient irrigation technologies are adopted. As a result of this finding, the government of Uzbekistan adopted a policy of irrigation efficiency which led to a drastic increase in efficient drip sprinkler systems in the last three years. And in India, solar-powered pumps for irrigation have reduced carbon emissions and improved access to irrigation with multiple benefits for food and nutrition security, health and livelihoods for smallholder farmers. While not without challenges, projects to tailor this technology to specific circumstances, minimizing environmental impacts and maximizing social and economic benefits, have had remarkable successes.
