Revealing the interactions between global biodiversity change and human food security

Lead Research Organisation: University College London
Department Name: Genetics Evolution and Environment

Abstract

Sustainable development, aimed at ensuring human well-being while protecting the Earth's natural environment for future generations, is one of the greatest challenges of the 21st century. The United Nations recently agreed on a set of Sustainable Development Goals (SDGs), which encompass both environmental and social targets, including halting biodiversity loss and ending hunger across the world. Importantly, these goals concern highly interlinked sectors: biodiversity and agriculture (largely for food production) interact within ecosystems, and regions of food consumption interact with areas of food production within the global food system. In this project, we will focus on evaluating and explaining the interactions between food production and biodiversity, and we will also quantify the role of trade linkages in shaping the impacts of food production on biodiversity globally.

In order to effectively progress towards the SDGs, it is necessary to understand the interactions between biodiversity changes and human food security. These interactions can take a number of forms, most obviously that agricultural land use for food production is one of the greatest pressures on biodiversity. However, biodiversity changes may also impact food production. Indeed, certain groups of species provide important services that support agriculture, such as pollination, nutrient cycling, and control of insect pests. Ecosystems with a higher diversity of species within these groups have been shown to have higher levels of certain ecosystem services, such as pollination, and to have more stable agricultural production through time.

In our previous research, we have used models of biodiversity to understand how human use of the land for agriculture impacts biodiversity across the world. We have also used these models to make predictions of how biodiversity might change in the future under different scenarios of how humans will use the land. However, these models have so far been relatively crude, which has prevented an understanding of the interactions between biodiversity and food security.

In this project, we will advance biodiversity models in three important ways to explain the interactions between biodiversity change and food production. First, we will ask how the effects of agriculture on biodiversity vary in different environments (e.g. differing in climate or in the surrounding natural habitat). This will help us identify those environments where agriculture has a smaller impact on biodiversity. Second, we will assess how the characteristics of agricultural systems, such as productivity, fertilizer and pesticide use cause different impacts on biodiversity. This will allow us to identify agricultural practices with smaller effects on biodiversity. Third, we will explore how different groups of species are impacted by agriculture. This will allow us to identify instances where there is feedback from biodiversity change to food security, for example if key groups of species such as pollinators are lost more than other species.

With our improved models, we will identify where around the world food production and biodiversity change are most strongly interacting. We will also investigate how global trade in agricultural products is linked to biodiversity change, to identify where food consumption has particularly strong biodiversity impacts, potentially in remote regions of the world. Finally, we will make future predictions to identify the pathways of development in human societies that are likely to lead to smaller or larger interactions with biodiversity.

Together, the model improvements and applications will provide a much better understanding of the interactions between biodiversity change and food security at the global scale, which will be key to guide environmental, conservation and agricultural policies aimed at achieving the UN Sustainable Development Goals.

Planned Impact

There are three main ways by which our proposed research will achieve societal impact. First, by feeding into international environmental processes; second, by guiding national-level policies; and third, by informing various stakeholders (governments, farmers, food retailers and consumers) of their impacts on biodiversity.

Our results will feed into international processes through established links forged by Tim Newbold and Carole Dalin. Biodiversity-focused processes include the Intergovernmental Platform on Biodiversity & Ecosystem Services (IPBES), the Convention on Biological Diversity's Global Biodiversity Outlook, and the United Nations Global Environment Outlook. Given that we address interactions between biodiversity conservation and food security, more important will be the links to international processes that consider the links between environmental change and food security. In this regard, we will work with the UN Food and Agriculture Organization (FAO) and the SDGs, in the latter case via the United Nations Sustainable Development Solutions Network (SDSN). Our previous modelling work has already produced indicators that are used by many of these processes, including IPBES and SDSN.

To inform national policy, we are working with the policy team at the Royal Society, who work with the UK government on issues around sustainable food security, with the International Institute for Environment and Development (IIED), whose work informs national policies in developing countries, and with the Sustainable and Healthy Food Systems (SHEFS) Project, which is working with national policy partners in India and South Africa. We will also respond to public consultations from the UK Department for Environment, Food & Rural Affairs (DEFRA).

Our results linking biodiversity impacts of food production to the end-consumer of these food products via international trade will inform several relevant actors of the global food system such as food retailers, supply-chain companies, farmers and individual consumers. Tim Newbold is involved in an expert group, convened by the Cambridge Institute for Sustainability Leadership (CISL), developing a tool (that uses his previous models) for businesses to assess the impact of their supply chains on biodiversity. The refined models that we develop in this project will be even more relevant for the tool, and we intend (with CISL) to seek NERC innovation follow-on funding to make this happen. Carole Dalin has also established links with Cervest, a risk management platform for agri-food markets, who are interested in using the results of the research we propose here.

To support all of the above activities, we will maintain a project website through which we will make available all of our research findings and model predictions.
 
Description We have made considerable progress on our research objectives since the last review period. Our analysis of the response of local biodiversity to characteristics of the surrounding landscape has yielded some interesting and compelling results. We show that local biodiversity is strongly affected by specific landscape characteristics. In particular, distance to forest and the percentage of natural habitat in the surrounding environment play a key role in maintaining local biodiversity across land-use types. These results have implications for how landscapes are managed in the face of future agriculture requirements to feed a growing human population. We aim to submit this piece for publication in the Spring of 2020 initially to PLOS Biology. We have also completed a major objective, by compiling the first global database of pollinator species (the initial version of which was published in Ecography). The compilation of the first global database of pest controlling species is also nearly complete. Analyses using both of these databases are now well underway. A study on the response of bumblebees to climate change, in which Tim Newbold was involved, was published in the journal Science).

Work is currently on-going on a number of new analytical studies. An extension of the above piece on landscape characteristics that looks more closely at the specific natural habitat requirements to maintain biodiversity across land uses is currently in the planning phase. Similarly, results from the above analytical piece are being used to project the impacts of landscape characteristics on biodiversity in space and under future scenarios of land-use change. Two pieces of work with a focus on insects are under way, one on the differing responses of insects to land use and climate change and one with a specific focus on pest controlling species.

In addition to this analytical work, we have been able to publish a reflection piece, summarising the main impacts of agricultural production on biodiversity and water resources. This work reflects on the findings of two recently published reports by the EAT-Lancet Commission and the Intergovernmental Panel on Climate Change. We highlight some important areas for future research that need to be considered to better understand the impacts from agriculture on biodiversity and water. This article has been published in the journal One Earth. In a similar thread, we have a perspective piece in revision at One Earth. This paper describes the complexities of the global system due to the interactions between biodiversity, food production and international trade. We highlight the need for biodiversity to be given more focus in research to get a more complete picture of the interactions and trade-offs involved.

A second review piece, under review at Environmental Science and Technology, investigates current economic and ecological models that are used to quantify biodiversity impacts. This review analyses methods that aim to connect how the consumption of agricultural commodities have impacts on habitats and species where production takes place.
Exploitation Route For now, we will continue to work on our research objectives throughout the rest of the period for which we have funding.

Description We have had impact on intergovernmental environmental negotiations and on public awareness of biodiversity declines. The Biodiversity Intactness Index, put into practice for the first time by Tim Newbold, continues to be at the core of intergovernmental reporting on biodiversity. For example, it played a key role in the recent, influential global assessment published by the Intergovernmental Platform on Biodiversity and Ecosystem Services, and is currently included in the draft list of indicators for the Convention on Biological Diversity's post-2020 Biodiversity Framework. Our ongoing work will allow important updates to this indicator as well as permitting versions of the indicator to be produced for key groups of species important for agriculture (pollinators and pest control species). One of the post-doctoral researchers on the project (Monica Ortiz) has strong connections to institutions in their home country of the Philippines, which is considered a biodiversity hotspot. Pending acceptance of an article on the impacts of intensive agriculture on local biodiversity, Monica is also exploring links to disseminate this information to government and non-government stakeholders. Tim Newbold's paper on declines of bumblebees with climate change was featured in many news outlets around the world, and was featured in several television and radio broadcasts. Tim delivered a public lecture on his bumblebees work, which is now available on the UCL lunch-hour lectures YouTube channel (https://www.youtube.com/watch?v=QdWQXSBW2JY). We continue to make connections for our impact-related work. Tim Newbold was invited to spend a day at the European Commission DG Environment in Brussels, to discuss the role of biodiversity indicators and modelling in Europe's post-2020 biodiversity strategy. Staff at the European Commission are interested in using the Biodiversity Intactness Index and the models that underpin it (which were developed by Tim Newbold) in their future work. Carole Dalin had a meeting with Bryan Vadheim and Oliver Walker at Vivid Economics, a consultancy on environmental economics, responsible for the 'Natural Resources' practice area. They are developing an economics-centered global model for land use management, which will be ready by October 2019. They will keep us in contact, they are interested in the expected outputs from this project, in particular the different impacts on biodiversity that agricultural land uses may have. They advise on the: design and implementation of business and public strategies; impact and efficiency of commercial and policy initiatives; costs and benefits of investment decisions under uncertain future scenarios consequences of changing market conditions, particularly on competitiveness; and building of effective institutions and necessary capacity Their clients are industry leaders, governments, international financial institutions, think tanks, and opinion leaders. Tim Newbold has had discussions with Sarah Giles, from the policy team at the Royal Society, who remains interested in using the outputs from this project in the future.
