Dr Nick Girkin

I am Assistant Professor in Environmental Science at the University of Nottingham, and lead the Sustainable Ecosystems and Global Change group. The group is currently split between the University of Nottingham, and Cranfield University where I was previously Lecturer/Senior Lecturer in Plant Soil Systems (2020 - 2023).

I am a plant and soil ecologist, and biogeochemist, working to address key environmental challenges with a focus on quantifying climate change impacts on ecosystem processes and people, and identifying opportunity for greenhouse gas flux mitigation and enhancing carbon sequestration in soils and plants. I am a Fellow of the Royal Geographical Society, member of the British Ecological Society (and co-chair of the Peatlands and Wetlands group), and a Fellow of the Higher Education Academy.

My research interests and teaching span four key areas:

1. Plant regulation of rhizosphere physics, chemistry, biology, and function. Plants regulate the rhizosphere, but soil processes are frequently species dependent, and my group’s current research is demonstrating it can also vary between crop genotypes. I have a particular interest in understanding regulation of GHG emissions and carbon sequestration.

2. The impact of management, including regenerative and sustainable agriculture on soil health, carbon, and nitrogen cycling, as well as crop yields. My research spans temperate (cereals and horticulture) and tropical agroecosystems (predominantly tea, coffee and cocoa plantations). I am interested in how changes in management ranging from alterations in tillage to the adoption of agroforestry provide environmental benefits over time, and builds climate and livelihood resilience.

3.  The resilience of ecosystems and ecosystem processes. I am interested in the impacts of climate and land use change on the ecology and biogeochemical processes across a range of ecosystems, including agriculture, peatlands, wetlands, and grasslands, in temperate and tropical regions.

4. The implementation of nature based solutions for climate change, including how such solutions can contribute to climate change adaptation and mitigation, with examples ranging from constructed treatment wetlands, to afforestation, and peatland restoration/conservation.

The impacts of regenerative farming on soil carbon, structure, and biodiversity across spatio-temporal scales

Naomi's project is focussing on the interactive effects of different regenerative farming practices (including zero tillage, cover cropping, and reduced agrochemical inputs) on soil carbon sequestration and biodiversity in UK agroecosystems.

Eda Knights

(Lead supervisor Stéphanie Swarbreck, NIAB)

Net zero Wheat

Eda's project is focussing on unravelling the impacts of genotype x management (tillage and nitrogen application) interactions in wheat, and the opportunities for the mitigation of greenhouse gas emissions, including nitrous oxide.

Gideon Asamoah

Developing low cost indicators for sustainability and soil health for West African Cocoa plantations

Gideon's research focusses on quantifying the impacts of different regenerative farming practices on ecological productivity soil health, and carbon sequestration in cocoa production in Ghana and Cote d'Ivoire.

Bright Laboan

Assessing the potential of organo-mineral fertilisers for West African cocoa farms

(Lead supervisor Prof Ruben Sakrabani, Cranfield University)

Bright's PhD project focusses on the impacts of emerging organo-mineral fertilisers on cocoa crop yields and soil health in Ghana.

Conor Walthall

Net Zero Crops: Genotypic controls over greenhouse gas production in linseed

Conor's PhD focusses on plant regulation of greenhouse gas emissions in linseed, with the aim of untangling physiological and morphological mechanisms of control, and identifying plant traits that can underpin the development of low emission crop varieties.

Hamza Othman

Assessing the climate resilience of farms and farming communities in the Niger Delta

Hamza's PhD is focussing on quantifying the impacts of different climate stressors on the resilience of agroecosystems in Nigiera, and the farming communities who rely on them for the provision of fundamental ecosystem services. 

Kirby Robinson

The organic geochemistry of the Central African peatland complex

(Lead supervisor Dr Arnoud Boom, University of Leicester)

Kirby's research at the University of Leicester focusses on the first detailed assessment of the organic geochemistry of the Central African peatland complex.
