Protecting animals, ecosystems and biodiversity is one of the big challenges of our time. With climate change dramatically impacting the planet and transformations in society such as housing development and urbanisation, protecting ecosystems and the life they sustain has become increasingly challenging. One of the most difficult challenges that environmental researchers and protection organisations now face is fully understanding how the elements of a fragile ecosystem react to global and local changes.
In a new Dr Alice Johnston, Lecturer in Environmental Data Science, says ecosystem and biodiversity research needs major change, to include models that can be widely applied across environmental research, rather than just focusing on specific problems and questions.
“Robust land management policies and practices are needed to promote and restore ecological resilience in the face of human-driven change. Models are increasingly used to support environmental decisions, providing an understanding of the possible consequences of these policies and practices before their implementation” says Dr Johnston. “But because most ecological models are developed for specific purposes, it’s a real challenge to build the broad information base needed to predict how complex ecological systems respond to multiple management practices across diverse landscapes.”
“What we need are fewer ecological models that are collaboratively developed to account for multiple scales. Such an approach would bridge distinct fields of ecology as we know them today to identify organising principles for biodiversity, providing an evidence-base for safeguarding ecosystems across interrelated environmental problems.”
Dr Johnston advocates capitalising on progress that has already been made in ecological modelling to systematically test the predictive power and computational cost of existing scale-specific models at multiple scales. AI-driven methods like those used in climate change forecasting could then extrapolate biodiversity predictions from local to global environmental problems.
Such advances in ecological modelling have relevance to several ongoing projects in 撸撸视频, including Defragmenting the fragmented urban landscape (DEFRAG) and Restoring Resilient Ecosystems (RestREco). Both Natural Environment Research Council funded projects are taking a multi-dimensional and multi-scale approach to understand how a range of ecosystems (urban, grassland, forest) both respond to disturbance and support critical services such as air quality and water regulation.
