Climate resilience of Uganda’s Power sector- a new peer-reviewed book chapter using the CLEWs methodology

A new book chapter authored by KTH-dESA PhD student Vignesh Sridharan explores the resilience of Uganda’s power sector to climatic changes. The chapter—co-authored by Eunice Ramos (KTH), Mark Howells (KTH), Constantinos Taliotis (The Cyprus Institute), Paul Basudde  (UG-MEMD), and Isaac V. Kinhonhi (UG-ERA)—sheds some light on the implementation of minimum environmental flow conditions on major Ugandan Rivers and their impact on hydropower generation. A water balance model developed in WEAP is used to inform an electricity sector expansion model developed in OSeMOSYS, to analyse the impact of climatic changes and the implementation of flow regulations on the cost of electricity generation. The figure above illustrates the methodology of the model development. The study concludes that irrespective of the climate, if key environmental services have to be maintained, there will be a reduction in hydropower generation in the country, and proper adaptation measures need to be taken to avoid disruptions in power supply.

KTH-dESA support the Libyan and Tunisian consultation workshops on the sustainable development of  shared aquifer waters

The two national consultation workshops for Libya and Tunisia were held back-to-back between 01-4 April 2019, in Hammamet in Tunisia.  A delegation of authorities and experts from the water, energy, agriculture and environmental fields discussed enhancing transboundary cooperation in the North Western Sahara Aquifer System (NWSAS) shared between Libya, Tunisia and Algeria. The discussions during the two workshops were informed by a participatory assessment of intersectoral “nexus” trade-offs and synergies in managing the NWSAS, developed jointly by the Water Convention Secretariat serviced by UNECE, the Global Water Partnership Mediterranean (GWP-Med), the Sahara and Sahel Observatory (OSS) and KTH. Youssef Almulla, PhD candidate at KTH-dESA, presented the key challenges and suggested solutions related to the energy sector in the NWSAS region. Furthermore, he presented the results of the GIS-based modelling developed to address key nexus questions in a quantitative manner. These presentations (and others) served as inputs for the group discussions that elaborated on packages of multi-sectoral solutions and their possible implementation at national and transboundary levels.

A CLEWs publication on cross-scale impacts of local decarbonisation decisions

A new paper by PhD candidate Rebecka Engström explores cross-scale nexus impacts from a local case example in Sweden. The implementation of an ambitious municipal plan to reach a fossil free local energy system by 2030 is modelled through a set of stylized scenarios. Land use and water impacts are traced through the system, and results show that impacts on these resources are highly path-dependent, both in terms of magnitude and in terms of geography. Some decarbonisation pathways have larger water impacts nationally, while others may affect land use locally or internationally more. Each of these resource systems is linked to different Sustainable Development Goals (SDGs). The study thereby highlights that trade-offs and synergies between SDGs are non-static, but vary between pathways. It concludes that local action to tackle climate change and enhance local sustainability are imperative, but needs to consider non-local implications across the CLEW-nexus and across the SDGs.
