'We value our heritage most when it seems at risk; threats of loss spur owners to stewardship.' (David Lowenthal, 1996) Climate change is the greatest challenge of our times, according to the Intergovernmental Panel on Climate Change, and combating its impacts is one of the key UN Sustainable Development Goals. One symptom of our rapidly warming world is accelerated sea level rise. With 150 million people across the world living within 3 feet of today's water levels, the consequences will affect each of us directly or indirectly. Former president of Kiribati, Anote Tong, describes the relationship between sustainable development and climate change as 'inseparable'. For Small Island Developing States, addressing development challenges while planning for climate change is a constant struggle. Kiribati is a low-lying island nation in the Pacific Ocean, and is often defined by the grim prognosis for its future. Yet there are pressing development challenges which affect people's lives in Kiribati today, such as access to clean water, and dealing with increasing amounts of waste. As Claire Anterea from the environmental organisation Kirican has said 'we will drown in rubbish before we drown in water'. This project team will work with Kirican, in Kiribati, to co-design a community-level programme towards sustainable development. This grassroots approach will inform the broader development field about the specific challenges facing Kiribati, and Small Islands Developing States more generally. If heritage in its most fundamental sense is about what we value collectively, and want to preserve for the future, then it is entirely logical that academics and practitioners in the heritage field should care about the environment and sustainable development. According to a recent UNESCO report, climate change poses the greatest risk to world heritage, yet heritage concerns are not as prominent as they should be in this field. One of Kiribati's adaptation strategies is to plan for 'migration with dignity' for its population of over 110,000. We will consult with heritage organisations in Kiribati to find out how and whether they are planning for climate change and even potential displacement. This responds to more general concerns amongst global preservation professionals, such as archivists, about their own role within climate adaptation. Should the relocation of cultural resources and archives of climate-vulnerable nations be planned? How could such an enterprise could be managed practically and ethically, and by whom? The research team will also collaborate with the artist and cultural expert Natan Itonga to make a film evoking the rich cultures of Kiribati. This is part of a creative process that aims to understand the local meaning of heritage in Kiribati, and promote awareness of what is at stake. Overall, this project explores both the scope and limitations of attempts to 'preserve' heritage in face of rapid environmental change or when the natural environment itself is heritage at risk. What can be 'saved' at all when the impacts of climate change are so catastrophic for nations like Kiribati, and is it still meaningful to talk about sustainable development? This project works through ideas of loss but focuses on connections; specifically, finding enduring connections to potentially lost objects to carry us into the future, caring for our current connections to land, water and non-human life, and accepting moral connections between the most polluting- and vulnerable- countries. As Anote Tong said to participants at the Delhi Sustainable Development Summit in 2013: 'Are we here to secure the future of each other's children or just our own?' Within this project, heritage is positioned as a pivotally important field of expertise for understanding that global challenges of magnitude will nonetheless be felt locally, everywhere.

ALTER aims to demonstrate that there are real and lasting benefits for wide scale poverty alleviation, particularly for the rural poor, by tackling soil degradation at a range of spatial scales, from field to landscape, and using opportunities within agricultural as well as severely degraded land. Throughout the world, soil degradation impacts on the health, wealth and well-being of rural people in many different ways. Soils have a key supporting role in maintaining agricultural yields, water availability, water quality, resources for grazing animals and other ecosystem services. Some are perhaps less obvious but still valued such as maintaining habitats to support honey-bees and local wildlife. In Africa, soil degradation is recognised as a major constraint to alleviating poverty in rural communities. We have chosen to work in Ethiopia and Uganda where there are contrasting issues of soil degradation in mineral and organic soils are a result of agricultural land use but similar reliance in rural communities' on a range of benefits from soils. Solutions to soil degradation are not simple and require a much better understanding of how people benefit from soils, what they stand to gain if they can improve the condition of the soils that they manage whether for crops, livestock, timber production or as semi-natural areas, what they would need to do to accomplish this and what barriers may prevent this. In parallel we need to gain better insight into the likely success of different management options to improve soils. Ultimately these options will require some form of investment whether that be via money, time, resources or other mechanisms. We will investigate the relative pros and cons of these mechanisms from the perspective of local people, organisations involved with markets for Payments for Ecosystem Services and national objectives in alleviating poverty. A broader view of carbon benefits and trading is an opportunity to invest in lasting improvements in degraded ecosystems and the livelihoods of the poor that depend on these. All of this research and evidence building needs to be placed into the context of climate change. We need to establish that whatever might be suitable, acceptable and viable for tackling soil degradation now will have long-term benefits to local people and that these benefits will not be negated by the on-going changes to local climate. The ALTER project is an international consortium between The James Hutton Institute (UK), University of Aberdeen (UK), Hawassa University (Ethiopia), The Ethiopian Government's Southern Agricultural Research Institute (SARI, Ethiopia), Carbon Foundation for East Africa (CAFEA, Uganda) and the International Water Management Institute (Nile Basin & Eastern Africa Office, Ethiopia). This team brings together natural scientists, social scientists and economists to work together with rural communities and other local decision-makers and facilitators to improve our capacity to predict how human-environment linked systems respond to incentives and other drivers change. This predictive capacity is needed to be able to explore whether different options for change could result in substantive poverty alleviation.

River deltas comprise only 1% of global landscapes, yet support over half a billion people. Deltas are tightly coupled social-ecological systems (SESs), but human exploitation, environmental degradation and threats from climate change increasingly threaten these delicate interfaces between land and water. The intractable development challenge addressed by this bid is how to avoid the collapse of South and SE Asian deltas as functioning, highly productive social-ecological systems in the face of human development and the projected consequences of climate change. The proposed Living Deltas Hub focuses on the delta SESs of three major rivers in South and Southeast Asia: the Red River and Mekong (Vietnam) and Ganges-Brahmaputra-Meghna (GBM: Bangladesh, India). Deltas form part of wider river basins and so the Hub will also engage with other riparian country researchers, in Thailand, Cambodia, Laos and Myanmar. The stakes for the project are clear: 70% of the Mekong delta is highly vulnerable to flooding with 7 million people at risk. Sea level rise in Bangladesh could displace between 3 and 13 million by 2100. SE-Asian mega-deltas produce 88% of the world's rice, but the 98cm of sea level rise predicted under IPCC AR5 (2014) would render 16% of arable land in Bangladesh and 25% in Vietnam unusable by 2100. Upstream damming and sediment retention is also a major threat, with resulting delta subsidence putting 12 million people in 23 Asian cities at risk from water inundation. As human impacts increase, the need for locally-rooted sustainable development strategies underpinned by traditional knowledge becomes ever greater. The GCRF Living Deltas Hub will co-develop the transdisciplinary frameworks needed to understand delta SESs, and will work with delta-dwellers and policymakers to develop solutions that can help realise the UN Sustainable Development Goals (SDGs) in delta contexts. The Hub is novel - no other existing or previous international delta initiative has specifically addressed the SDGs by co-creating new natural and cultural heritage understandings of deltas. It is timely, as it addresses the crucial challenges of SE Asian delta degradation early in the lifespan of the SDGs and so contributes to the development of SDG monitoring and planning - globally and regionally, as well as in country contexts. The Hub is innovative as it emphasizes transdisciplinary integration of the earth and life sciences, social sciences, humanities and arts, to address these common challenges The Hub will operate on a model of 'equitable partnership', involving delta-dwellers and the research community in developing knowledge and policy for better delta futures. The Hub comprises six innovative work packages co-developed with Global South partners and research institutes addressing specific in-country and delta-scale needs. Its new knowledge will serve to build capacity and shape policy at local, national, regional and global levels. The Hub will have lasting impact through improved livelihoods and more resilient communities, sustainable management and conservation, improved monitoring of SDG indicators and better policies for sustainable development. The Hub brings together a transdisciplinary team of experts and practitioners from Global 'North' and 'South'. Hub strengths are in: coupled human and natural systems analyses; demography and international development; natural hazard modelling and coastal resilience; environmental monitoring and modelling; policy and practice of resource management, hazard, risk and resilience; SDG-focused analyses of delta systems and their vulnerability to hazards; justice and governance; behavioral finance; delta nutrition and food security; and gender-sensitive research. Working together with stakeholders from delta countries, the research team have the knowledge, expertise and track record to build new understandings of delta change, new partnerships, and new solutions.

The world is moving into an unprecedented era of dam-building with more than 3700 large dams currently planned or under construction, much of which are in DAC list countries. These projects have the potential to contribute significantly to the economic and social changes that underpin global Sustainable Development Goals (SDGs). However, past experiences show that poorly designed and planned dam projects conversely may have large negative impacts on the poor, and exacerbate political instability and environmental degradation. This proposal seeks to create the knowledge base, capacity and capability for a 'Dams 2.0' future, in which dams built in DAC list countries are selected, designed and operated to support resilient and sustainable national, regional and global development in a 2.0 degC world. This will be achieved by understanding and assessing dams as interdependent human-nexus (water-energy-food-environment) system interventions and enabling stakeholders to negotiate economic, social, political and ecological impacts despite future uncertainty. Our proposal will address this ambitious goal through unique cross- and inter-disciplinary research and capacity development partnerships between three sets of key actors. First, our project will stimulate collaboration between several UK centres of research excellence in development, water-energy engineering, economics, food security, climate change, finance and ecology (the universities of Manchester (UM), Cambridge, University College London (UCL), Surrey, Newcastle and Southampton, the International Institute for Environment and Development (IIED), and the International Water Management Institute (IWMI). Second, we will consolidate links with a carefully selected network of researchers and policy-makers in 4 countries/regions (The Centre for Science and Industrial (CSIR) - Water in Ghana, Technological University of Yangon in Myanmar, Jordanian Institute of Science and Technology in the Middle East region, Institute of Economic Growth in Delhi, India). Thirdly, we will seek to work collaboratively with some of the world's most influential development organisations such as The World Bank (WB), International Union for the Conservation of Nature (IUCN), the International Finance Corporation (IFC), The Nature Conservancy (TNC), the International Hydropower Association (IHA), and the Climate Bond Initiative (CBI). Dams 2.0 is led by a team with a proven track record in successfully managing large consortium grants across multiple countries and disciplines that focus on applied development and policy impact challenges. Our work will provide tailored guidance and build capacity for water-energy-food systems management in each of our case studies regions. In addition, our project will create a framework and accompanying software toolkit for dam system design and training worldwide. This online software will link several open access water, energy, food, and ecological simulation models to state-of-the-art decision-making under uncertainty approaches. This software will be made accessible via an associated suite of online training materials (games & modules we plan to develop with IWMI and the World Bank) for use by dam selection/design/operation teams globally in a range of settings.

Humans have massively altered flows of nitrogen on our planet, leading to both benefits for food production and multiple threats to the environment. There are few places on Earth more affected than South Asia, with levels of nitrogen pollution rapidly increasing. The result is a web of interlinked problems, as nitrogen losses from agriculture and from fossil fuel combustion cause air and water pollution. This damages human health, threatens biodiversity of forests and rivers, and leads to coastal and marine pollution that exacerbates the effects of climate change, such as by predisposing reefs to coral bleaching. Altogether, it is clear that nitrogen pollution is something we should be taking very seriously. The amazing thing is that so few people have heard of the problem. Everyone knows about climate change and carbon footprints, but how many people are aware that nitrogen pollution is just as significant? One reason for this is that scientists and policy makers have traditionally specialised. Different experts have focused on different parts of the nitrogen story, and few have the expertise to see how all the issues fit together. This challenge is taken up by a major new research hub established under the UK Global Challenge Research Fund. The "GCRF South Asian Nitrogen Hub" is a partnership that brings together 32 leading research organisations with project engagement partners from the UK and South Asia. All eight countries of the South Asia Co-operative Environment Programme (SACEP) are included. The hub includes research on how to improve nitrogen management in agriculture, saving money on fertilizers and making better use of manure, urine and natural nitrogen fixation processes. It highlights options for more profitable and cleaner farming for India, Pakistan, Bangladesh, Nepal, Afghanistan, Sri Lanka, Bhutan and the Maldives. At the same time, the hub considers how nitrogen pollution could be turned back to fertilizer, for example by capturing nitrogen oxide gas from factories and converting it into nitrate. The fact that all the SACEP countries are included is really important. It means that lessons can be shared on good experiences as well as on whether there are cultural, economic and environmental differences that prevent better management practices from being adopted. It is also important from the perspective of international diplomacy, and provides an example to demonstrate how working together on a common problem is in everyone's interest. It puts the focus on future cooperation for a healthier planet, rather than on the past. The South Asian case provides for some exciting scientific, social, cultural and economic research challenges. The first is simply to get all the researchers talking together and understanding each other. There are dozens of languages in South Asia, matching the challenge met when different research disciplines come together. This is where developing a shared language around nitrogen can really help. There are lots of nitrogen forms ranging from unreactive atmospheric nitrogen (N2), to the air pollutants ammonia (NH3) and nitrogen dioxide (NO2), to nitrate (NO3-) which contaminates watercourses, and nitrous oxide (N2O) which is a greenhouse gas. The impacts of each of these are being studied to provide a better understanding of how they all fit together. The result is an approach that aims to give a much more coherent picture of the nitrogen cycle in South Asia: What is stopping us from taking action, and what can be done about it. One of the big expectations is that the economic value of nitrogen will help. India alone spends around £6 billion per year subsidising fertilizer supply. It means that South Asian governments are strongly motivated to use nitrogen better. At which point research from the South Asian hub can provide guidance on where they might start.
