Agricultural intensification and expansion are major drivers of the current global biodiversity crisis. It is therefore essential that we understand the nuances of the relationship between agricultural land-use, biodiversity and the ecosystem services it provides in order to mediate the effects of increasing global demand for food. While there is much work on enhancing ecosystem services on farmland, less is known about how to support a broad range of biodiversity. Indeed, while we have some understanding of the impacts of agriculture on some species and functional groups, we do not have the broad taxonomic understanding that is required if we are to avoid the unintended consequences of managing landscapes for a single or narrow range of outcomes. Even less is known about how biodiversity directly contributes to farmland production, meaning it can be devalued by farmers.
Biodiversity can be measured in a wealth of ways. An increasingly supported measure of biodiversity is that of functional diversity: the range of ways by which organisms influence ecosystem functioning. Understanding how changes in biodiversity driven by agriculture affect functional diversity is crucial for many reasons. Firstly, understanding the effects of environmental change on functional diversity provides greater generality and predictability than focussing on species’ identities alone. Secondly, the most affected species may be providing similar or unique ecological functions, leading to a loss of that function. Finally, functional traits provide the link between biodiversity and ecosystem resilience and function, and therefore ecosystem services.
The aim of this project is to gain an understanding of the relationship between agricultural land-use – in the context of the wider landscape – and functional diversity, covering a wide range of functions and taxonomic groups via the following questions: 1) which functional groups are most impacted by agricultural land-use?; 2) are communities in agriculturally intensive landscapes more functionally homogenised (and less resilient) compared to other land-uses?; and 3) how can we design agricultural landscapes to avoid loss of functional diversity and ecosystem services? The project will lead to new insights and syntheses concerning how multiple species are impacted by agriculture and how these impacts alter ecosystem functioning.
Figure 1. Functional diversity & ecosystem services – Biodiversity is linked to multiple ecosystem services: ladybirds provide pest control over aphids; jay’s disperse acorns and regenerate oak woodlands; beavers provide multiple services through engineering; many of our invertebrates pollinate to provide the food we eat. Dynamic landscape measurement – To understand how landscape structure influences biodiversity, we need to measure it in a meaningful way. We will develop dynamic and mechanistic measures of landscapes. Global case study – Distribution of the PREDICTS data, a potential source for this research. UK case study – A variety of National Trust owned landscapes (pictures from www.nationaltrust.org.uk/). Agricultural scenarios – The land-sharing, land-sparing continuum, one scientific framework under which agricultural scenarios could be developed.

The research will consist of four parts: (1) development of functional diversity metrics which provide a link between functional diversity and ecosystem functions; (2) measuring agricultural landscape structure and intensity in meaningful ways; (3) application of these metrics to a national or multi-national case study to understand the links between agricultural landscape structure and functional diversity; (4) development of agricultural land-use scenarios which reflect both policy decisions, and forward looking ‘future nature’ approaches.
You will have the opportunity to combine UK-based fieldwork on National Trust sites, with a (macroecological) study – using the PREDICTS database – into global effects of agriculture on functional diversity.
Training and skills
Students will be awarded CENTA2 Training Credits (CTCs) for participation in CENTA2-provided and ‘free choice’ external training. One CTC equates to 1⁄2 day session and students must accrue 100 CTCs across the three years of their PhD.
You will receive training in cutting edge ecological modelling and remote sensing techniques. You will also benefit from the range of applied and theoretical ecology expertise of the supervisory team. The fieldwork component of the project will allow you to develop specific ecological survey techniques. Additionally, you will be part of the growing Ecology & Biogeography group at the University of Birmingham, which has a number of researchers across all career stages in the general field of ecology. Through external collaborations you will have the opportunity to build your network.
Partners and collaboration
International Institute for Applied Systems Analysis (IIASA) is the CASE partner for this project.
The PhD project has three external partners. Prof. James Bullock at UK Centre for Ecology & Hydrology, Prof. Matthew Heard at the National Trust, and Dr. Martin Jung at International Institute for Applied Systems Analysis (IIASA). All have a wealth of expertise in functional and landscape ecology, with links to defining forward-looking policy-relevant research questions. The link with UK CEH will provide you with access to data from the Biological Records Office, and the ASSIST and AgLand projects. The link with National Trust will provide you with access to their sites across the UK. The link with IIASA will likely be in the form of a summer studentship with the Young Scientists Summer programme. Dr Jung has worked extensively with the PREDICTS data and can provide insight into this.
If you wish to apply to the project, applications should include:

Although there is the option for a fieldwork component to the project, given this fieldwork is UK-based, it fits within current restrictions due to COVID, and all relevant Health & Safety measures will be taken. Should restrictions tighten, the research can focus on the global macroecological analysis instead.
