Carbon sequestration in nutrient-deprived agricultural soils in SSA seems to hold a great potential to tackle two of the most pressing issues of our time: food insecurity and climate change. Carbon-rich soils increase the resilience of agricultural systems due to their improved water holding capacity, soil aggregation, and nutrient supply and hence, contribute to food security. At the same time, carbon sequestration in soils is regarded as one important nature-based solution to mitigate climate change. Nevertheless, the concepts proposed by scientists, how to improve soil health and soil fertility vary widely, and large discrepancies exist around the need for chemical inputs to quickly increase food and other biomass production. The different approaches might result in potential trade-offs between high levels of crop yields and carbon sequestration. During the two panel discussions, we would like to have a closer look at different land management practices and their synergies and trade-offs regarding climate change mitigation and current and future food production.
The guiding questions to the panel are:
→ What are the technical and socio-economical potentials of different soil management approaches on the given cropland (ISFM, conservation agriculture, organic agriculture, …) for (A) achieving food security and (B) carbon sequestration?
→ What are the tradeoffs associated with each of those approaches (currently and in a situation of advanced global warming)?
→ Is there a corridor within which those approaches can meet and achieve good results for crop production and eventually food security on one side and carbon sequestration on the other side under different ecological and socio-economical conditions in tropical countries, in particular Sub-Saharan Africa?

Panelists, presentations and background information day 1
Gatien Falconnier is Systems Agronomist at CIRAD, based in Harare, Zimbabwe. He holds a PhD in Production Ecology and Resource Conservation from the University of Wageningen in the Netherlands. His research focuses on the contribution of agroecological intensification to poverty alleviation, food security, and climate change adaptation and mitigation, in the smallholder context of the Global South. This contribution is assessed using experiments with farmers, participatory research and farm/crop modelling.
Lydie-Stella Koutika is a soil scientist also acting as Director for Research Centre on Productivity and Sustainability of Industrial Plantations (CRDPI) at Pointe-Noire, Republic of the Congo. She obtained an engineer degree in agronomy with the specialization in soil science and agro chemistry at the Timiriazev Institute at Moscow, Russia in 1991 and a PhD in soil science at the Université Henri Poincaré, (merged to Université de Lorraine), Nancy, France in 1996.
For the duration of her career, she has been fascinated with soil organic matter (carbon and nitrogen) and phosphorus cycling in different ecosystems. During the last decade, she has been working on forest plantations, especially on how to sustain inherently nutrient-poor soils in the Congolese coastal plains.
She has been a “Research in Brussels” fellow (2003-2004), an International Rothamsted Research fellow, UK (2009-2010), an international TWAS-ENEA fellow (September 2018-May 2019), Italy and a member of ‘The Phosphorus Sustainability Research Coordination, Network (P RCN) University of Arizona. She is a member of Scientific and Technical Committee (STC) of the ‘4 per 1000’ “Soils for food security and climate Initiative” since 2016 and member of Global Soil Biodiversity Initiative (GSBI) since 2019. She is a laureate of ‘African Union Kwame Nkrumah Regional Scientific Award for Women’ (2014), The World Academy of Science (TWAS) -Al-Kharafi Prize (2018) and FAO Glinka World Soil Prize (2021).

Rolf Sommer is director of the department of Agriculture and Land Use Change at WWF in Germany. Previously he worked as Principal Scientist at the International Center for Tropical Agriculture (CIAT) in Nairobi, Kenya.
Developing and finding sustainable management solutions addressing the complexity of achieving food and nutritional security, sustainable agricultural development, the conservation of nature, biodiversity and agro-ecosystem functioning has been at the core of Rolf’s work ever since. This includes protecting or rehabilitating soil fertility and health at field level, improving the livelihoods of smallholders through improved, competitive and eco-efficient productions systems at farm level, biodiversity, nature and landscape protection and rehabilitation at the watershed /regional level, and carbon sequestration and climate change mitigation at global scale.
Rolf holds a PhD in Agronomy and a MSc in Biology, and in the last 20 years have published over 50 peer-reviewed articles and numerous conference proceedings and online publications (see http://scholar.google.com/citations?user=tAIw8ykAAAAJ&hl=en).
