Professor Andrew Geddes' research on international migration has directly impacted upon the thinking of officials and the subsequent reshaping of policy at national and international levels concerning connections between environmental change and migration. Impact has occurred in several countries and at different governance levels. The result is that a previously deterministic policy debate about environmental change triggering mass flight is now based on a changed and far more sophisticated understanding of the evidence with different assumptions now informing policy development. Geddes was appointed in 2009 by the UK Government's Chief Scientific Advisor to be a member of the 6-member Lead Expert Group overseeing the `Foresight' report Migration and Global Environmental Change: Future Challenges and Opportunities (MGEC) for the UK Government Office for Science, published in 2011. The report and associated work has had major international reach and has informed policies and practices in UK government departments (DFID, DEFRA) and the agendas and operations of the European Union (especially the Commission), World Bank and within the UN system.
Research at Oxford's International Migration Institute (IMI) on the driving forces of global migration processes, conducted in conversation with international stakeholder groups, has significantly affected the ways in which migration is conceptualised and viewed by experts, international organisations and governments involved in formulating migration and development policies. The new perspective arising from IMI's research fundamentally challenges the common assumption that migration is driven by poverty and distress, and holds that migration is in fact an integral part of the process of human and economic development. This view was adopted by the United Nations in the UNDP Human Development Report 2009 and has significantly influenced the UK government's Foresight report on Migration and Global Environmental Change.
A comparative methodology to assess the impact of climate change in different countries, implemented by Gosling for a report commissioned by the UK Department of Energy and Climate Change (DECC), informed EU negotiations at the 2011 UN climate change conference in Durban, South Africa. The conference concluded with the Durban Platform for Enhanced Action - a `road map' by which global legal agreement on climate change is to be implemented no later than 2015. For the first time, government ministers and their advisers attending an international conference were able to compare the impact of climate change in different countries, including those where scientific institutions have limited research capacity.
The United Kingdom is today better adapted to climate risks as a result of a sustained programme of research completed by the School into the impacts of climate change on ecological, social and infrastructural systems. This work has had significant and continuing impact on the design and implementation of UK (and international) climate adaptation strategies and policies, especially with regard to flooding, the built environment and water and coastal management. Decision-support tools (such as climate scenarios and options appraisal) and direct policy advice produced by the School have been used by numerous public and private sector organisations to inform and guide their adaptation strategies and investments.
Preference-satisfaction models of welfare dominate environmental policy but are problematic both in respect to the value placed on environmental goods and as a basis for environmental decision making. The Philosophy Department at the University of Manchester (UoM) has developed an alternative characterisation of well-being, along with tools for its measurement and employment in policy making. Impact is delivered via a UK-based project on climate justice, focused on a need to conceptualise, measure and map vulnerability to the impacts of climate change associated with flooding and heatwaves. The framework developed has had a major influence on adaptation planning at both local and national levels, allowing authorities to identify concentrations of climate disadvantage, and to formulate policies that address specific sources of disadvantage in different locations.
Information on the potential impacts of climate change across the world, and on the effects of policies designed to reduce emissions, is fundamental to inform the development of climate mitigation and adaptation policy. Research conducted at the Unit has been critical to the establishment of a target 80% cut in UK carbon emissions by 2050, as enforced by the Climate Change Act (2008), and provided an affirmation of the relevance of the 2f0b0C global mean temperature rise target central to national and international climate mitigation policy. Research into the global consequences of climate change, particularly for water resources and river flooding, has been used by the Department for Energy and Climate Change (DECC) to assess the impacts of un-mitigated climate change and the effects of different mitigation policy options.
Significant climate change is forecast for the Middle East by the end of this century, leading to — amongst other things — greater water scarcity and falling agricultural productivity. LSE research resulted in the development of the Palestinian Authority's first climate change adaptation strategy. This in turn led to the creation of a Palestinian national committee on climate change and, with the implementation of specific recommendations from this research, the strengthening of climate change planning within the Palestinian Authority. The research also shifted regional priorities for the United Nations Development Programme (UNDP), which subsequently included climate change in its 2011-2013 Strategic Framework as a policy priority for development work in the occupied Palestinian territory.
Professor John Broome's research on the ethics of climate change and on our associated responsibility to future generations has had a significant impact on those involved in policy decisions concerning climate change. Most notably, Professor Broome is serving as Lead Author for Working Group III of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (the IPCC), which is a unit of the United Nations and the leading international body for the assessment of climate change: its work is directed by, and approved by, governments. He is also a member of the IPCC's Synthesis Report. In addition, he has raised public awareness of the ethical issues with which he has grappled through a series of publications and lectures.
Lived experiences of ordinary people and how they rationalise events provides rich insights for several disciplines e.g. medicine. With climate change, whilst the value of anthropogenic activity is increasingly recognised, models based on positivist scientific rationality still dominate. What is yet unclear is how a global citizenery understands climate change through its own individual and group "lived experiences". This research is significant in that it seeks to conceptualise and theorise what is meant by the "lived experience" of climate change and how this shapes the "lay rationality" and actions of people in both the developed and the developing world.
Hope's research in developing the PAGE2002 model of climate change has been used extensively by government agencies in the UK and US, as well as the IMF and the international community in order to improve their calculations for global carbon emissions and setting carbon emissions targets. The model was used in the UK government's Eliasch Review, in order to calculate the costs and benefits of actions to reduce global deforestation; by the US Environmental Protection Agency, in order to calculate the marginal impact of one tonne of CO2 emissions; and the IMF, whose calculations using the PAGE2002 model form the basis for their guidance on carbon pricing.
