I am a classic geography nerd so what really excites me is the interaction between humans and the natural world. I love discovering pieces of the puzzle and fitting them together to form the bigger picture of our life on earth – how we evolved alongside nature, how we used and misused natural resources to fuel our development and how can find a way to re-balance our relationship with nature to live sustainably.

General nerdiness aside I am particularly interested in issues of sustainability, natural resources management, biodiversity conservation and environmental governance.

My PhD research uses Madagascar as a case study to investigate the intersection of these issues; the environmental-trade offs of mining in biodiversity hotspot. Madagascar is endowed with extensive and varied mineral resources which so far remain relatively untapped. It is also considered one of the world’s hottest biodiversity hotspots, home to an exceptional variety of flora and fauna with extremely high rates of endemism, much of which is confined to the ever-dwindling forests. There is substantial overlap between Madagascar’s mineral resources and its biological wealth which raises the dilemma – how can Madagascar use its mineral wealth to develop without trading-off biodiversity?

I will investigate this question by evaluating the benefits and environmental impacts of different forms of mining in Madagascar (large-scale industrial, small-scale formal and informal artisanal) in an attempt to determine which forms of mining could yield the greatest benefits for the least environmental costs. So far, I have used cutting-edge statistical methods for impact evaluation to determine whether Madagascar’s largest mine is on track to deliver no net loss of forest (as a proxy for biodiversity) through application of the mitigation hierarchy and biodiversity offsetting. If successful, this would show the economic contributions of industrial mining (which in Madagascar cannot be understated) can be achieved without trading-off biodiversity.

Next, I will combine quantitative and qualitative methods to investigate the impacts of artisanal gem mining. In Madagascar, artisanal mining is illegal, unregulated, insecure, and often unsafe. However, it employs up to 500,000 people, often providing a ‘last line of defense’ when other modes of income generation fail. As such, it makes a vital contribution to local livelihoods and can stimulate local development. Whilst the majority of artisanal mining (particularly for gold) is long-term and diffuse, over the past 30 years there have been a series of high-profile rushes for gemstones, involving tens of thousands of miners converging on area to dig for riches. First, I will investigate the validity of media reports that artisanal gem rushes within the Eastern rainforests led to extensive deforestation, forest degradation and illegal bushmeat hunting. Then I will compare the impacts (positive and negative) of an artisanal gem rush with a small, formal, ethically-minded gem mine that set up at the same location after the rush had ended. I want to investigate community perceptions of the two different forms of mining and the associated environmental impacts to determine which yielded the greatest benefits for the lowest costs.

Finally, I plan to do some large-scale scenario modelling of existing alternatives to mining to determine whether there is a viable alternative that could an generate equivalent economic contribution to mining and if so, what would be consequences of this on land cover?

The research will span the environmental and social sciences, although focussing mostly on the former, and integrate both primary and secondary sources of data. Primary data will be obtained through fieldwork and analysis of satellite imagery. The project will involve in-depth use of Geographical Information Systems and R statistical software.

The infographic is a work in progress but it aims to visually depict the idea behind biodiversity offsetting.

The UN Sustainable Development Goals (SDGs) lay out society’s ambition to deliver social and economic prosperity for all, while conserving nature on land and sea (SDGs 14 and 15 respectively). However, ‘business-as-usual’ approaches to solving social and economic development challenges may compromise our ability to achieve the SDGs that are focused on eliminating our impacts on species, ecosystems, and the climate (Spaiser et al. 2017; Hickel 2019). How can we enable nature to thrive through the Great Acceleration? 

Sophus zu Ermgassen’s research takes an interdisciplinary approach to exploring global solutions. His core PhD is focused on how to resolve the potential conflict between SDGs 9 (the expansion of the world’s infrastructure networks, with a minimum of $60 trillion projected to be spent on new infrastructure by 2040), and SDGs 14 and 15. In this context, he focuses on understanding the role and outcomes of No Net loss/Net gain policies and biodiversity offsets, a globally-significant mechanism for attempting to resolve perceived trade-offs between infrastructure and biodiversity (Bull and Strange 2018). His methods include evidence-synthesis, spatial mapping, causal inference and surveys.
