La prise en compte de la consommation de capital, qu’il soit fabriqué ou naturel, est devenue une question fondamentale dans toute évaluation de la performance économique ou mesure de la richesse créée aux niveaux sectoriel ou économique global. S’il est plus simple de mesurer cette consommation dans le cas du capital fabriqué ou dans celui des ressources minières, les méthodes proposées sont loin de faire l’unanimité dans le cas des ressources naturelles dites faiblement renouvelables, comme c’est le cas des eaux souterraines.

Le présent travail se propose d’évaluer la valeur économique de la consommation de ces dernières dans le cas Maroc, et plus particulièrement dans le secteur productif, c’est-à-dire dans l’irrigation. La méthode adoptée se base sur le prix hédonique, tel que reflété dans le prix de la terre, et sur l’évaluation des multiplicateurs calculés à l’aide de la matrice de comptabilité sociale. Les résultats démontrent que la surexploitation des nappes souterraines ne contribue que marginalement à la création de la richesse, mesurée par la valeur ajoutée, et que les faibles gains obtenus ne justifient nullement la perte d’un capital aussi stratégique de points de vue social etéconomique.

    Africa is acutely affected by the ongoing global democratic recession. In 2020, a military coup took place in Mali.

Yet polling data and activism on the ground shows African youth believe in and are prepared to fight for democracy. ...

    If the recent peaceful transfer of power in Madagascar heralds a new trend, then the Malagasy people can dream big. For decades, the exercise of economic-cum-political power in the hands of a tiny elite has held the entire nation hostage. Today, the high poverty rate—around 80% (2021) stands in stark contrast to the natural resource abundance of this huge enormous island. There is hope, however, that with political stability, the Plan d’Émergence Madagascar (PEM) President Andry R ...

    This year, the Conference of the Parties (COP27) will be held in in Sharm el-Sheikh, Egypt. On the outset of this auspicious occasion, it is befitting to reflect upon contemporary climate adaptation and mitigation policies, from a southern and African point of view. Indeed, climate change is one of the stickiest policy problems of the 21st century, because it is inherently a global and multidimensional problem entailing a bundle of policy features. Following the consecutives shocks ...
