Recently, Paulownia spec. has been introduced to Central Asia in a number of small plantations. Paulownia yields timber of high quality for applications such as furniture, house construction, boat construction, and surf boards, or skis. Thus, Paulownia might offer a much-needed raw material for this region and beyond. However, Central Asia is largely occupied by drylands so that Paulownia needs irrigation. Against the background of frequent water stress across the region, this study aimed at assessing the water consumption and water productivity of that tree, using a 6-year-old plantation as study site. Trees were planted in May 2017 and cut back to their stumps in 2018. Daily crop evapotranspiration was calculated after the Penman-Monteith approach, whereby the crop coefficients were inherited from actual evapotranspiration values which stemmed from the remote sensing approach S-SEBI. Water consumption per tree was 1741 l, 4461 l, 4500 l, and 4407 l over the growing seasons 2020, 2021, 2022, and 2023, respectively. The water productivity for the stem wood over the whole time-span from planting in 2017 until 2023 was 1.59 g l-1 and 5.65 ml l-1. Given the high quality of its timber and its range of high-value applications, it can be concluded that the water consumed by Paulownia enables higher value timber and timber products than other trees that grow in comparable areas of Central Asia.

Political tensions over water management in the Central Asia region have intensified since the Soviet era, as ecological issues like the drying Aral Sea and seasonal hydropower disruptions impact downstream countries. The paper discusses the region’s water governance challenges, including climate-induced uncertainties, water resource demands, and the limited capacity of local research institutions. While Central Asia’s governments have initiated reforms, including new infrastructure and agreements, resilience in water management remains underdeveloped. The paper also explores the role of higher education institutions in fostering capacity-building for sustainable governance, emphasizing the need for local expertise and regional collaboration. The proposed establishment of a Central Asian water research platform aims to enhance science-policy integration, promote sustainable water governance, and support informed regional cooperation on transboundary water issues.

The water, energy, and food (WEF) nexus is being promoted as a conceptual idea for achieving sustainable development, that describes the interconnections and interdependencies between those three sectors. The main objective of this article is to operationalize the WEF nexus concept in lift-irrigated areas of Uzbekistan through involving local stakeholders, to investigate the WEF nexus within the lift-irrigated agriculture of the Kashkadarya region, an area heavily reliant on the Karshi Canal system. The study is grounded in the urgent need for sustainable development, with a focus on enhancing intersectoral cooperation between water, energy, and food sectors. A case study methodology was employed, incorporating semi-structured interviews with experts, alongside local farmers and scientists. Data were analysed using the qualitative analysis software, Atlas.ti. The results indicate significant challenges to intersectoral cooperation in the WEF nexus, including lack of trust, communication barriers, differing priorities, and insufficient political will. However, the findings also highlight the potential benefits of improved cooperation, such as enhanced resource efficiency, reduced operational costs, and mitigated risks from environmental stressors like drought. The study concludes that, according to stakeholders’ opinions, while the WEF nexus presents critical opportunities for advancing sustainable development in Uzbekistan, substantial barriers must be addressed to realize these benefits. Recommendations include promoting sustainable agriculture to reduce water dependency, improving energy security by diversifying energy sources, and raising awareness of the WEF nexus’s importance. Furthermore, fostering stronger stakeholder cooperation is crucial for achieving Uzbekistan’s Sustainable Development Goals (SDGs) by 2030.
