March 2020 Agroecology and carbon neutrality: what are the issues? Pierre-Marie Aubert, Marie-Hélène Schwoob, Xavier Poux

Key Messages The TYFA scenario is based on the generalisation of organic farming (abandoning synthetic pesticides and fertilizers), the extension of agroecological infrastructures and the adoption of healthy diets, to feed 530 million Europeans by 2050 (despite a 35% drop in production). It leads to a 40% reduction in GHG emissions (35% for direct non-CO2 […]

March 2020 Battle over cocoa prices: a missed opportunity for a fairer and more sustainable chocolate Frédéric Amiel

A last-ditch action The three-week threat by Ivory Coast and Ghana of a blockage of cocoa sales for the 2020-2021 season (production is generally sold several months in advance on futures markets) marked a turning point in a sector historically characterised by a balance of power unfavourable to producers. While the price, set on international […]

March 2020 IPCC report on the ocean: what are the main climate change-related threats? Jean-Pierre Gattuso

The IPCC report on the ocean, of which you are one of the co-authors, has already had a considerable global impact. He makes a striking observation of the impact of climate change on the ocean. Indeed, it appears that the impacts of climate change on the ocean and cryosphere as well as future risks are […]

March 2020 European Union: Five years to deliver the Green Deal Lola Vallejo, Nicolas Berghmans

The political guidelines for the new Commission (2019-2024), proposed by Ursual von der Leyen highlights (six)1 key political fields.

March 2020 The ongoing biodiversity loss and how it can be stopped Yann Laurans, Aleksandar Rankovic

Key Messages The Global Assessment shows that biodiversity collapse on the continents is primarily due to land use changes related to agriculture, particuarly linked to the increased consumption of animal products. Regarding oceans, pressure from fisheries is the main cause of the decline. This suggests the adoption of commitments relating to food and agricultural systems. […]

Climate change, biodiversity erosion, demographic change, urbanisation, air pollution, soil degradation, natural disasters, industrial accidents, health crises, social mobilisations, international summits… This is the first atlas gathering all the data on the ecological crisis of our time.  Book available at Les Presses de SciencesPo

March 2020 Agricultural value chains facing the biodiversity challenge: the cocoa-chocolate example Frédéric Amiel, Yann Laurans, Alexandre Muller

Key messages The cocoa/chocolate value chain is characterised by a high concentration of processors. There has been a fourfold decrease in the number of grinding plants in Europe in recent decades, which has decreased the sector’s adaptability to sustainable production’s constraints, leading to the maintenance of a structural cocoa overproduction at the global level.   […]

March 2020 The Citizens’ Climate Convention: what for? Sébastien Treyer

It is clear that the ecological transition is not progressing or transforming the society as rapidly as needed, a fact we demonstrated in a study published towards the end of 2018. Topics such as the electricity mix and the carbon tax have drawn considerable attention and controversy. Experts and academics have identified the level of […]

March 2020 How can developing countries reduce methane emissions? Benoît Blanc

Methane, a greenhouse gas forgotten in the fight against climate change? For the last 10 years, each year, 10 Mt of methane2 have been emitted more than the chemical reactions in the atmosphere can degrade, and the atmospheric concentration of this pollutant has increased,3 placing it on a warming trajectory at 4°C. It is therefore […]
