Introduction
I graduated in Organic Agriculture and Food Systems at Hohenheim University in October 2014 with a thesis about Amaranth breeding, together with the Institute of Plant Breeding. During my studies, I also collaborated with the Italian Seed State Authority and the Institute for Animal Production (Hohenheim University). After graduation, I collaborated with the Milan State University and with FiBL Switzerland. I then obtained a PhD in agronomy at INRA Bordeaux, working on global modelling for organic agriculture. Currently, I am an associate professor in agronomy at Bordeaux Science Agro

Article
Full-text available
The future of the livestock sector is critical due to its significant contributions to global warming, water and air pollution, biodiversity loss, as well as ethical considerations on animal welfare. Beyond the evidence that a decrease in livestock production can limit its environmental footprint, livestock also plays a positive role in most agroec...
Article
Full-text available
Agricultural trade and globalization pose new challenges for resource management and governance. In particular, many countries are dependent on imports of non-renewable mineral phosphorus (P) fertilizers for their agriculture. We propose a framework to assess the possible impacts of future disruptions in P resource availability by comparing countri...
Article
Full-text available
Organic agriculture is widely accepted as a strategy to reduce the environmental impacts of food production and help achieve global climate and biodiversity targets. However, studies concluding that organic farming could satisfy global food demand have overlooked the key role that nitrogen plays in sustaining crop yields. Using a spatially explicit...
Article
Full-text available
Livestock animals play a key role in organic farming systems by providing nutrients for croplands through manure production and nutrient-dense food for human consumption. However, we lack global, synthetic view about livestock productivity in organic farming and about its differences with conventional farming. Here we fill this important gap of kno...

La mise en œuvre à grande échelle des principes de l'agroécologie et de l'agriculture biologique est uneoption proposée pour répondre aux enjeux de durabilité de l'agriculture. Toutefois la capacité de telssystèmes à répondre aux enjeux de sécurité alimentaire globale reste posée. La place de l'élevage estau centre du débat, notamment en raison de...
Article
Full-text available
The debate about organic farming productivity has often focused on its relative crop yields compared with conventional farming. However, conversion to organic farming not only results in changes in crop yields, but also in changes in the types of crops grown. To date, the effects of such changes on global crop production have never been systematica...
Thesis
Organic agriculture is often proposed as a promising approach to achieve sustainable food systems while minimizing environmental impacts. Its capacity to meet the global food demand remains, however, debatable. Some studies have investigated this question and have concluded that organic farming could satisfy the global food demand provided that ani...

Full-text available
The debate on whether Organic Agriculture can feed the world is highly controversial. Currently most studies have focused on the relative productivity of organic vs conventional farming at the crop level, without taking into consideration nutrient availability. Our main objective is to assess the supply of organic products under scenarios of dramat...
Article
Full-text available
Cropland use activities are major drivers of global environmental changes and of farming system resilience. Rotating crops is a critical land-use driver, and a farmers’ key strategy to control environmental stresses and crop performances. Evidence has accumulated that crop rotations have been dramatically simplifed over the last 50 years. In contra...
Article
The global demand for cacao has recently increased. To meet this demand, the cultivated area has been expanded in tropical forest areas and production has intensified by replacing traditional agroforestry systems with monocultures. This has led to a loss of biodiversity in cacao-growing areas. More sustainable production systems such as agroforestr...
Poster
Cocoa production systems can vary from a mono-cropping (MC) full sun plantation to a highly diversified successional agroforestry (SAFS). Mono-cropping is still the most common one but recently agroforestry (AF) systems have raised more interest because of their expected long-term resilience. Nevertheless, information about the influence of croppin...
Poster
Full-text available
Cocoa cropping systems vary from full-sun monocrops to highly diversified agroforestry systems, which combine the cocoa production with by-crop such as bananas or plantains and trees with different functions. Additionally, these systems can be organically or conventionally managed. Although labour demand is one of the main activities contributing t...
Article
Full-text available
Alternative agricultural systems, like organic and local agriculture, are becoming increasingly important in Europe to the detriment of conventional methods. As a matter of fact, sustainable agriculture, which started as a niche sector, has been able to conquer a significant share of the European agro-food market. Institutional promotion along with...

Today, the ability of Organic Agriculture to “feed the world” is a highly debated topic. Several authors has attempted to compare the productivity of organic agriculture versus conventional agriculture. Those studies do not consider the consequences of a potential dramatic development of organic systems on crop productivity due to the possible risk of a limited availability of nutrients to sustain the production. A second limitation of such studies lies in the lack of accounting for differences in crop rotations between organic and conventional systems. The main objective is to address those two limitations and to assess the food production capacity of organic agriculture if it was to develop dramatically at the global scale using a spatial-explicit modelling approach.
