Biography
I am an ecologist interested in how agricultural landscapes best support biodiversity and ecosystem functions, especially how pollinators and their multiple stressors (such as habitat loss, pesticides and climate change) affect pollination services and farmers' agricultural resilience. I enjoy interdisciplinary research, and my projects combine ecological field data and model predictions with psychology and economic valuations to understand the uptake and effectiveness of different pollinator conservation practices across Europe (A View Across Fields) and under climate change scenarios (Plan Bee). I am also interested in how agricultural practices expose bees to multiple pesticides and how these effects scale beyond traditional studies focusing on single substances in focal fields. My ecotoxicological research, led by Dr Rundlöf at Lund University, supports the basis for a more realistic, systems-based pollinator pesticide risk assessment that we are helping to define in the IPol-ERA project. Impact-driven, my research is transdisciplinary. I enjoy communicating and disseminating my work to multiple stakeholders: farmers, agricultural industries (levy boards, seed companies), land managers, beekeepers, scientists, and conservation organisations.

- Title
- A view across fields: interdisciplinary perspectives for bees in agricultural landscapes
- Summary
- Biodiversity conservation must be both functional and sustainable to respond to global environmental change. By modifying environments, humans are critical to this. However, international policy lacks an appreciation beyond the 'rational' (ecology and economic) of what motivates or constrains people's conservation efforts (Fig. 1). We will address this through the lens of pollinator conservation in agricultural systems. First, we will extend and validate an ecological model to generate systematic predictions of two bee species' (with contrasting ecologies) reproductive output and pollination services in different landscape contexts. We will then combine this information with predictors of people's engagement (e.g. perceptions) in conservation with specific practices costs to provide stakeholders (policymakers and farmers) with robust, generalisable, and holistic recommendations for pollinator conservation. Furthermore, we integrate ecological and economic perspectives into a validated ecological-economic model to elucidate how landscape-scale management of high-scoring conservation practices can maximise cost-effectiveness for farmers, policymakers and society. In doing so, we aim to demonstrate how a paradigm shift to an interdisciplinary approach can provide policy-ready solutions to land-use change and ultimately increase engagement in biodiversity conservation.

- Title
- Plan Bee: interdisciplinary pollinator conservation for changing agricultural landscapes
- Summary
- Biodiversity conservation must be ecologically effective and socially sustainable to mitigate environmental change, now and in the future. We will address this through a lens of bee conservation in agricultural systems, where multiple drivers such as habitat loss, climate change and pesticide risk threaten bees and pollination services. Our project will extend our ecological model to generate predictions of bees' reproductive output and pollination services in response to habitat loss and climate change. We will test these drivers in isolation and combination to improve the assessment of the combined effects of these multiple drivers on biodiversity. We will then use our ecological model to explore strategies to handle these combined effects - pollinator conservation practices, to fight the twin challenges of habitat loss and climate change in agricultural systems. Finally, we combine this information with people's intent to implement these conservation practices to identify synergies (e.g. increased bee populations and crop pollination services) or trade-offs (e.g. increased bee populations at a cost to the farmer) that may facilitate or impede future bee conservation efforts. Thus, we aim to demonstrate how a paradigm shift to an interdisciplinary approach can provide policy-ready solutions to environmental change and ultimately increase engagement in biodiversity conservation.
