We are going to talk about cocoa deforestation, land demand for sustainability, trade-offs, limits, root causes of the ecological and climate breakdown, degrowth and care.
To address the climate and ecological breakdown, multiple forms of interventions are being deployed, such as zero-deforestation commitments for commodity supply chains, renewable energy, or nature-based solutions. Leveraging Earth Observation data and spatial analyses, this thesis aims at bringing an improved understanding of the land use outcomes and the limitations of these sustainability interventions, and at exploring how to improve approaches to sustainability.
Starting by assessing the traceability and transparency of cocoa supply chains and the direct and indirect deforestation driven by cocoa in the two major producing countries, Côte d’Ivoire and Ghana, it shows that narrow sustainability interventions limited to a single crop and specific segments of the supply chain face leakages and are insufficient to stop deforestation.
Moving to the global level, the thesis assesses major land demands foreseen by 2050, showing that, together, land-based sustainability targets and pledges for conservation, restoration, renewable energy and bioenergy, and major land demands for food, fiber and timber amount to an area larger than the ice-free land surface and have important overlaps.
The thesis concludes with an analysis of the underlying causes of the climate and ecological breakdown. To mitigate the global land squeeze, it calls for breaking silos and for a systemic approach to sustainability – ultimately seeking sufficiency to reduce overconsumption and production.
