The global energy sector is facing considerable pressure arising from climate change, depletion of fossil fuels and geopolitical issues around the location of remaining fossil fuel reserves. Energy networks are vitally important enablers for the UK energy sector and therefore UK industry and society. Energy networks exist primarily to exploit and facilitate temporal and spatial diversity in energy production and use and to exploit economies of scale where they exist. The pursuit of Net Zero presents many complex interconnected challenges which reach beyond the UK and have huge relevance internationally. These challenges vary considerably from region to region due to historical, geographic, political, economic and cultural reasons. As technology and society changes so do these challenges, and therefore the planning, design and operation of energy networks needs to be revisited and optimised. Electricity systems are facing technical issues of bi-directional power flows, increasing long-distance power flows and a growing contribution from fluctuating and low inertia generation sources. Gas systems require significant innovation to remain relevant in a low carbon future. Heat networks have little energy demand market share, although they have been successfully installed in other northern European countries. Other energy vectors such as Hydrogen or bio-methane show great promise but as yet have no significant share of the market. Faced with these pressures, the modernisation of energy networks technology, processes and governance is a necessity if they are to be fit for the future. Good progress has been made in de-carbonisation in some areas but this has not been fast enough, widespread enough across vectors or sectors and not enough of the innovation is being deployed at scale. Effort is required to accelerate the development, scale up the deployment and increase the impact delivered.

Ecosystems are under threat worldwide - natural habitats are being lost and the remaining areas are degraded and fragmented. Developing countries in the tropics have some of the world's highest concentrations of endemic species, but very high rates of land-use change. Climate change is already affecting tropical species, and there is particular concern about whether they will be able to shift from areas that become too hot or dry, across fragmented landscapes, to reach refuges in montane regions. If land-use change and forest degradation continue too intensively in these countries, species and ecosystem functions will be lost, leading to detrimental impacts on the livelihoods of local people dependent on these lands. Habitats across a landscape can be thought of as an "ecological network", and these networks need to have sufficient habitat area, quality and connectivity to be functional. Robust ecological networks require stronger protection of existing habitat and restoration of degraded forest. Policy makers and nature conservation practitioners are increasingly thinking about biodiversity conservation at landscape scales, but continuing land-use change leads to difficult decisions about how to prioritise habitat preservation and restoration, and technologies are lacking to allow practitioners to be able to do this. There is huge potential for landscape prioritisation to be informed by NERC-funded research. We have developed a model based on ecological understanding of range shifts, which quantifies how different elements of a habitat network contribute to long-distance connectivity. This model can also identify the best habitat to preserve, or locations to target for restoration. We have also quantified biodiversity in fragmented tropical forest habitats, and shown how land-use change affects forest species, in particular the extent to which they can persist in selectively logged forest, small forest fragments, extensive plantations and intensive plantations. This knowledge can now be used innovatively with new technologies and data, particularly remotely sensed data, to enable large-scale sustainable land-use planning for tropical developing countries under climate change. This project will develop an online spatial decision support tool for planning robust and resilient habitat networks under climate change. Our tool will be co-created and tested with partners in Ghana, Indonesia and Malaysia, locations where landscape planning is urgently required to support the livelihoods of local communities and other stakeholders dependent on building resilient landscapes under environmental change . Our partner organisations are responsible for sustainable forest planning and biodiversity protection in their countries, balancing biodiversity and socio-economic needs of landscapes. Our partners have proposed specific case studies that exemplify the most pressing choices and alternative scenarios they face - our new tool will be applied with their existing data to highlight priorities for action. Priorities will be based on connectivity benefits for biodiversity, weighted by economic costs and stakeholder preferences. The most tangible and long-lasting output of this project will be the freely available web interface to our tool, backed by a high-performance computing cluster in Liverpool that will perform the analyses. This interface makes the tool globally accessible, and is vital for future users in developing countries, because computing power limitations would preclude them running a desktop version. The project will also provide face-to-face training to relevant stakeholders in our partner countries, and online tutorial materials tailored to the needs of developing countries. Hence we will build capacity for our tool to be used as part of multidisciplinary projects addressing development challenges in future, to find efficient solutions where vital networks of natural habitat coexist with the needs of local stakeholders.

Universal access to a secure electricity supply is essential for the economic development and welfare of the population of Burkina Faso. Rapid urbanisation and an increased use of air conditioning (AC) has led to an 8.4% annual increase in the country's electricity demand since 2010. The nation's generation capacity is unable to keep up, resulting in frequent power outages, and a 45% dependence on energy imports creating high and volatile costs for consumers. An uninterrupted and affordable electricity supply would increase household incomes; improve education of children; save time and money collecting alternative fuels, particularly for women; improve the productivity of businesses; and accelerate the installation of new electricity connections. These direct benefits would reduce current rates of social and economic poverty, unemployment, illiteracy and emigration in the country. Upgrading the country's electricity generation and supply system is a long-term challenge, but in the short-term, our project partners, the Government of Burkina Faso and national electricity utility, SONABEL, believe the implementation of demand side management (DSM) programmes (electricity efficiency and flexibility) in the housing sector (which accounts for 33% of national electricity use) would better balance supply and demand and unlock these beneficial development outcomes. The Government has also committed to reduce electricity demand and improve energy efficiency in homes to cut Green House Gas emissions and help mitigate the effects of climate change, a phenomenon that disproportionately effects the Sahel region where Burkina Faso is located and is itself further exacerbating electricity demand as households are increasingly using AC to stay cool. However, at present, there is almost no data on household electricity demand, efficiency or flexibility in Burkina Faso for a successful, evidence based implementation of DSM. The aims and objectives of this research and partnership building project will address this substantial gap in knowledge. The project has been developed collaboratively with the Government of Burkina Faso and SONABEL to ensure the research delivers the data and evidence they need. For the direct research, a socio-technical residential electricity study will be undertaken with 100 households in Ouagadougou. Field measurements of electricity demands and internal temperatures of homes will provide empirical insights into households' electricity load profiles, use of AC, time-of-use and peak loads. An efficiency and flexibility survey will be completed to understand households' current practices and opportunities for improving energy efficiency at home, as well as identifying load shifting and curtailment actions that households would be willing to implement to prevent power outages. Diversity in responses due to the socio-technical characteristics of the households and dwellings will be studied. Simultaneously a range of partnership building activities (e.g. research visits, project meetings, workshops, mini conference) will be undertaken. These are tailored to the stage of the project programme to either inform the delivery of the direct research or form a platform for discussion, dissemination and impact generation of the research findings. An international network of 6 Universities will be created where future research on energy and development challenges in Burkina Faso and other African countries will stem. The network will also act as a platform for ongoing mutually beneficial exchange of knowledge and skills. To deliver development impact within the project's life time, workshops with the Government and SONABEL will turn the research findings into evidence based recommendations to inform future policy and DSM programmes. Project partner GGGI will use their extensive network, to engage wider stakeholders and beneficiaries, so a range of routes to impact are achieved.

Illegal gold mining operations are a growing problem in Ghana, owing to the practice of alluvial mining techniques and the heavy use of toxic chemicals, which leads to significant pollution by cyanide, mercury, other heavy metals and organic contaminants, of the water sources that serve the local population. The mining and other local communities are thus deprived of access to clean water, leading to serious health problems. In addition to any chemical treatment of the effluent water, there is an urgent need to develop physical absorbents to remove the pollutants, which, however, need to be both efficient and cost-effective. Microporous zeolite materials are very effective absorbents and ion exchangers, which can be tuned to be highly selective towards adsorbate(s) of interest, with the accompanying release of non-toxic ions into the environment. They can be synthesised from readily available materials and are compact, cheap and simple to maintain in full-scale operations. This cross-disciplinary project will bring together an experienced team of geochemists, physicists, computational and materials scientists from academia and industry to develop efficient synthetic zeolites, made from naturally available minerals, for the cost-effective treatment of waste water from gold mines, before its discharge into the environment. The zeolites will be characterised and tested on a laboratory scale before up-scaling both synthesis and filtration process into an operational treatment plant to serve a local metropolitan population.
