Groundwater plays a critical role in supporting economic activities in Africa, particularly in regions affected by climate change-induced water scarcity. This study examines the economic implications of groundwater in relation to conflict dynamics in these regions. The findings underscore the need for developing equitable water management strategies to mitigate conflict and promote sustainable development in Africa.
This article looks at how to make fiscal, monetary and prudential policies greener in order to address the massive financing needs and major risks associated with climate change.
Starting with the observation, based on the recent experience of the financial and health crises, that the separate and independent implementation of monetary and fiscal policies undermines their effectiveness, this study also shows the need for, and strategic role of, a green policy mix that ensures the coordination of fiscal, monetary, and prudential policies to meet the challenges of climate change.
Agglomeration bonuses (ABs) are payments conditional on the contiguity of landowners’ conservation areas. It is widely accepted that, by encouraging landowners to cooperate, ABs promote more cost-effective biodiversity conservation than instruments targeting landowners individually. This article challenges this conclusion by studying the impacts of different AB designs, some of which explicitly aim to enhance cooperation while others do not. Specifically, we study whether differentiating the bonuses between internal (within-landholding) and external (between-landholdings) boundaries affects AB cost-effectiveness. Using an economic-ecological model and game theory, our simulations on realistic landscapes show that differentiating the two bonuses (in favor of internal ones) generally increases AB cost-effectiveness. The two bonuses are indeed largely substitutable, with internal outperforming external bonuses. However, when the regulator’s budget is tight, external bonuses can complement internal ones at the margin. The complexity of compensation between plots belonging to different landholdings is a key element in explaining these patterns. Given this complexity, the most cost-effective schemes are characterized by little or no cooperation between landowners. Regarding policy, we conclude that differentiated ABs are cost-effective schemes that should be part of the regulators’ toolbox.
Bioenergies from dedicated crops or wood have faced substantial criticisms due to their significant land requirements. Certain bioenergy pathways, such as biogas generated from crop residues, manure, or food waste, appear to be exempt from this criticism. However, these feedstocks are byproducts of agricultural activities that generate emissions not covered by current climate policies in most countries.
Dans tous les domaines de nos vies et face aux nouvelles fractures (climatiques et écologiques, du travail ou de santé, numériques ?) mais aussi de façon plus philosophique voire politique, et en la reliant à quelques-unes des grandes notions de notre époque, cet ouvrage explore les potentiels et la modernité d’une idée dans toute la force de sa jeunesse : la mutualisation.
Séminaire en présence d'Adam George (SOAS, University of London).
Adam George présente un modèle macroéconomique SFC environnemental britannique intégrant émissions de CO2 et investissements verts de tous les agents économiques. Le modèle trimestriel analyse l'impact des politiques énergétiques selon le rapport capital vert/capital conventionnel. Quatre scénarios fiscaux verts sont testés (2022-2035) : taxe carbone, investissement...
Le laboratoire GAEL (Grenoble Applied Economics Laboratory) et la Chaire Energie et Prospérité organisent un workshop sur l’économie de la bioénergie les jeudi 9 et vendredi 10 octobre 2025 sur le campus universitaire de Grenoble.
