Africa is speeding toward a new crisis: an explosive increase in air pollution, with all its human and economic costs.

Africa is by no means alone in suffering the modern curse of air pollution. No less than 92% of the world’s population is now exposed to pollution levels exceeding World Health Organisation limits.[1] Nor is Africa “over-represented” in the global death toll from air pollution as it stands today. The total of premature deaths attributable to each of the two main types of air pollution, ambient particulate matter pollution (APMP) and household air pollution (HAP), stood at around 3 million.[2] Of these, Africa accounted for around 250,000 premature deaths from APMP, less than its share of the global population would suggest, and over 450,000 premature deaths from HAP, roughly in line with its share. In comparison, it is China, with its 900,000 deaths from APMP and 800,000 deaths from HAP that dominated the global death toll in 2013. Continue reading

Le climatologue et l’instituteur

Par Laurent Bossard, Directeur, Secrétariat du Club du Sahel et de l’Afrique de l’Ouest (CSAO/OCDE)

(English version follows)

image-finding-problems-to-fit-solutionsDans le deuxième opus des Notes ouest-africaines du Secrétariat du CSAO/OCDE («Les impacts climatiques dans le Sahel et en Afrique de l’Ouest: Le rôle des sciences du climat dans l’élaboration des politiques » ), Carlo Buontempo et Kirsty Lewis du Met Office UK s’interrogent sur le rôle des sciences du climat dans la formulation des politiques.

J’avais envisagé d’intituler ce blog « Ne laissez pas les climatologues s’occuper (seuls) du changement climatique ! ». Après tout, les auteurs eux-mêmes ne soulignent-ils pas que les climatologues ne sont pas nécessairement bien équipés pour identifier les éléments essentiels du climat et du changement climatique au regard des problématiques humaines ? J’ai toutefois finalement renoncé  du fait d’une admiration sincère pour cette corporation dont la lourde tâche est de nous aider à construire un avenir meilleur pour la planète.   Continue reading

Africa’s Blue Economy: An opportunity not to be missed

By Dr. Carlos Lopes, UN Under Secretary General & Executive Secretary of the UN Economic Commission for Africa

Blue-economyThe world’s oceans, seas and rivers are a major source of wealth, creating trillions of dollars’ worth in goods and services as well as employing billions of people. Three out of four jobs that make up the entire global workforce are water-dependent. It is forecasted that the annual economic value of maritime-related activities will reach 2.5 trillion euros per year by 2020, while the International Energy Agency estimates that renewable energy from the ocean has a power potential sufficient to provide up to 400% of current global energy demand. Yet Africa’s blue potential remains untapped. Continue reading
