Article
Green manure can be a source of nutrients for crops to spare some of the mineral fertilizer required for sustainable intensification of agriculture in smallholder context. We explored with a calibrated model the potential of legume green manure to help spare mineral fertilizer for sustainable intensification of rainfed rice production in Madagascar...
Preprint
Identification of best performing fertilizer practices among a set of contrasting practices with field trials is challenging as crop losses are costly for farmers. To identify best management practices, an ''intuitive strategy'' would be to set multi-year field trials with equal proportion of each practice to test. Our objective was to provide an i...

Article
In the mountainous areas of South-East Asia, family farms have shifted from subsistence to input-intensified and market-oriented maize-based farming systems, resulting in a substantial increase in farm income, but also in new environmental threats: deforestation, biodiversity loss, soil erosion, herbicide leaching and soil fertility degradation. In...
Chapter
Crop models are powerful tools to explore agricultural impacts and adaptation to climate change. They are extensively used to predict the effect of climate change on agriculture. In this chapter, the authors review how crop models take into consideration climate variables and how they are used for climate change impact assessment studies, leading t...
Conference Paper
Rainfed agriculture on smallholder farms across the tropics is crucial for food security and livelihoods when availability of irrigated land is limited. Coarse-textured soils with low organic carbon and poor inherent fertility prevail in these systems (Tittonell and Giller, 2013). In the absence of sufficiently remunerative market, smallholders can...

Current cropping systems in Europe are characterized by high productivity but rely on simplification of crop rotations and high level of chemical/synthetic inputs which has led to soil, water and air pollution and loss of biodiversity (e.g. Stoate et al., 2009). Diversification of cropping systems with grain legumes offer the opportunity to improve...

Project
Identify efficient strategies that foster long term soil carbon sequestration in agricultural systems - Quantify and model soil carbon sequestration dynamics and its determinants in different agricultural systems at crop-soil, farm and landscape scales - Deliberate amongst stakeholders about soil carbon sequestration pathways - Share knowledge, tools and experience on soil management options Questioned on the 4/1000 initiative on soil carbon (C) sequestration to face climate change (CC), several Labex Agro units and their partners propose to pull together their research capacities in order to provide new insights in soil C sequestration, the DSCATT project proposes to explore the potential for sequestering C in cultivated soils, taking into account the sustainability of agricultural practices in the context of global changes. DSCATT operates at 4 sites (in Senegal, Zimbabwe, Kenya, and France). The project addresses 3 interrelated scales of fields, farms or territories. At field level, research focuses on how biomass production and soil C sequestration relate, in different soil and climate conditions. Two approaches complement each other. One studies at the soil-plant interface the processes regulating the forms and residence time of C in soils. It includes the analysis of interactions between nutrients and C storage, the role of deep roots and in soils with contrasting storage potentials. The other approach determines the C balances under different practices. Farms will be characterized in order to propose practices likely to improve complementarities amongst the activities of rural households. At this scale, DSCATT research will focus on farmers' practices (for crops, livestock, forestry…) and assess the impacts of farmers' practices on their objectives (income, food security…), taking into account their main constraints (cash, labour…). The project will assess the social and economic determinants of farmers’ decisions and of trade-offs between farm activities. At the territory (or farmers' network) level, the different compartments of agroecosystems and the organic matter flows will be studied. The project will analyze the role of the socio-economic and biophysical contexts and will test several possible changes and their impacts on soil C sequestration dynamics, economic performance of farms and food security. This scientific knowledge and the viewpoints of the farmers involved will be shared and used for a transdisciplinary assessment of several C sequestration strategies in agricultural soils. Considering changes and uncertainties, a multi-criteria and prospective evaluation approach is proposed. It will allow iterations between evaluation and redefinition of strategies to cope with global changes in agriculture. The sharing and dissemination of the knowledge enriched by the project will target several audiences (farmers, students and teachers, policy makers) through a variety of communication media and assessment tools. DSCATT will link the knowledge on processes governing the preservation of C sequestration and farmers' multiple objectives and constraints.
