Dr Lucie Büchi completed studies in population biology and genetics, followed by a PhD thesis in theoretical community ecology, at the University of Lausanne (Switzerland). She then worked 7 years as a researcher at Agroscope (Switzerland), the Swiss national centre for agricultural research. before joining the Natural Resources Institute in 2018. At Agroscope, she developed projects on the impact of cropping practices, such as reduced tillage and the use of cover crops, on crop production, soil fertility, weed competition etc. She also studied biological nitrogen fixation by legume cover crops, and developed a soil cover agri-environmental indicator for monitoring purpose for the Swiss government. At NRI, Lucie Büchi works as a crop ecologist with a focus on the management of cropping systems in tropical and temperate climates, and on sustainable agriculture approaches such as regenerative agriculture and agroecology. In addition, she is interested in interdisciplinary research around gender and intersectional inequalities related to agriculture, in the Global North and South.
Dr Lucie Büchi has a strong interest in finding solutions to decrease the impact of agriculture on the environment through innovative cropping practices, with a focus on crop production, nutrient cycling, and soil properties.
Among these, cultivation of cover crops, which are crops used only for the environmental services they could provide, and not for direct economic value, has been at the centre of many previous projects.
Lucie’s main research interests are:

Soils are key to sustain food production. An important component of soils is organic matter, which contributes to soil fertility and crop growth, and consists of about 58% carbon. This soil organic carbon also helps to fight climate change, as the more carbon is in the soil, the less in the atmosphere contributing to greenhouse effect and global warming. The primary objective of this project is to empower farmers to estimate the level of soil organic carbon content in their fields, through the assessment of soil colour. This easy and accessible method will be validated against laboratory assessment, which is usually more costly and time consuming. The project aims to develop a new, accessible method and will contribute to raising awareness on soil health and carbon sequestration that can be used to adapt farm management practices towards net zero targets.

Weeds represent a major pressure on food production worldwide, by decreasing yields and contaminating harvests. It is thus crucial to study weed ecology to better understand how to control them now and in the future. In particular, the question of which traits (i.e. characteristics) favour the invasion and growth of new weeds into arable fields is key to understand how weediness emerges. In this project, we addressed the question of the traits underlying weed emergence in the grass species Vulpia myuros, also called rattail fescue. This species originates from the Mediterranean region and has been naturally present in Europe for centuries. However, V. myuros has emerged as a weed in recent years, benefiting from changes in cropping practices, in particular the reduction of tillage intensity. This species thus offers a unique opportunity to study the early stage of its invasion of arable fields. The traits characterising weediness in V. myuros will be studied by phenotyping wild and weed populations, i.e. we will measure important traits along the life cycle of the plant, from germination to flowering and seed production. The phenotyping of these populations in a growth chamber and greenhouse set up will reveal the similarities and differences in important traits among wild and weed populations and identify traits that are important to explain weediness. This project will shed new light on the traits underlying weed emergence in a species that may pose problems for food production in the future, and provide insights for improved control methods.

The proposed project will bring innovation by quantifying, for the first time, the impact of cover crops and non-chemical weeding strategies on soil health, production efficiency, and juice quality in UK vineyards. Project outputs will include evidence-based recommendations for growers on the best ground management approaches to suit UK vineyards. Industry-wide uptake of these practices would demonstrate to the public, the horticultural sector and retailers that the viti industry is committed to achieving environmental and net-zero goals. We propose to carry out the first full-scale experiments and commercial trials of cover cropping and mechanical weeding strategies in UK vineyards to identify and tailor optimal soil management approaches for the UK industry. The trial sites will serve as long-term research facilities on commercial holdings in Kent, and our intention is that they host separate but allied future research on beneficial insects and soil pathogens. We intend to commercialise project outputs through an existing route.

Goal: We propose to perform a high-resolution multi-functional genomic and environmental characterization of Ethiopian highland agri-systems, focusing on Enset and ten regionally and globally important crops that together comprise a range of complementary cropping agri-systems in the Southern Ethiopian highlands, seeking to enhance their role in future resource provision, and generating clear economic and social impact on the livelihoods they support.

Goals: 1. Identify and assess trade-offs between intensification (maximising productivity and profits) and sustainability (provision of ecosystem services, climate and market resilience) in coffee monocultures and agroforestry systems
2. How to meet growing demand for agricultural products and sustain livelihoods of farmers, in a context of climate change and market variation, while maintaining ecosystem services that are required for production and society as a whole
