As the international community observed the UN World Water Day last Friday, March 22, two Central Asian countries were part of important talks at UN Headquarters in New York concerning water-sharing. Tajikistan and Uzbekistan have been engaged in a dispute over the building of a reservoir-type Rogun hydroelectric power plant in Tajikistan, which Uzbekistan has contended would disrupt flow to downstream countries, including itself. Uzbekistan, a country never absent from important meetings on water issues, proposed an alternative to the Rogun project involving the construction of smaller hydroelectric plants, which would bypass or avoid changes to the stream-flow regime. These talks bring attention to a broader nexus of water, climate and energy security in Central Asia that is worth watching closely by both regional leaders and the international community.
Water security in Central Asia
The uneven distribution of water resources poses serious problems in Central Asia. Although the sources of the largest rivers are formed in Tajikistan and Kyrgyzstan, the flow is significantly weakened by hydroelectric plants as they make their way to the downstream countries of Turkmenistan, Uzbekistan, and Kazakhstan. Accordingly, while the reservoir dam in Tajikistan collects water in summertime, Uzbekistan and Turkmenistan suffer from a lack of water for irrigation purposes, particularly during dry periods – the frequency of which has been rising. The effect on the agricultural economies of downstream countries is worrisome, with water shortages potentially inhibiting future development. Although a due diligence analysis of the project, facilitated by the World Bank, was recently conducted by an expert group, the Uzbek side refrained from supporting their findings. Instead, the Uzbek government points to a potential bias as the process was outsourced by the Tajik government to firms of their choice, without the input of all of interested parties.
The climate change aggravator
Aside from the unequal distribution of water resources, the destabilizing effects of climate change may add an additional layer of insecurity in the region. Two recent studies of the heat wave in 2010, which significantly impacted agricultural production in Russia, Kazakhstan and Ukraine, have concluded that the event had a 70-80% likelihood of being attributed to a “long-term climatic warming trend.” A 2009 report by the Eurasian Development Bank found that the main contributor to climate change in Central Asia has been a significant increase in ground air temperature, with the plains experiencing the highest rates of average annual temperature increases.

Colombia’s long-standing internal conflict and the country’s contribution to climate change share one common root cause: land concentration. Policies to strengthen access to land and to ensure sustainable land use might therefore hold the key to promoting peacebuilding in Colombia, while simultaneously reducing emissions.
As disasters wreak havoc all over South Asia, health impacts have increasingly emerged as a major concern for communities and governments in the region. It underscores the need for concerted efforts towards building synergies between the Paris Agreement, the Sendai Framework for Disaster Risk Reduction and the 2030 Sustainable Development Agenda, particularly now, in the post-disaster reconstruction phase, to ensure “building back better” and future disaster prevention.
In the Inner Mongolian county of Horinger, Northwestern China, afforestation efforts have transformed a barren, dusty landscape into a pine forest. Planting trees has diminished the sandstorms, boosted biodiversity and improved the environment generally. As the climate emergency worsens, the potential for planted trees to draw carbon out of the atmosphere is being re-examined. What can the world learn from the Chinese experience with afforestation?
Two events in August 2019 underlined the complexity of paving the way to a climate-neutral world: the publishing of the new IPCC report and the Amazon fires. Both events demand that climate diplomats move beyond a narrowed focus on energy in decarbonisation debates.
