Le changement climatique, un concept complexe et multidimensionnel

Les conséquences du changement climatique sont de plus en plus visibles au Maroc. Le schéma changeant des précipitations et de la sécheresse, l'augmentation des températures moyennes et des canicules, les inondations et l'augmentation du niveau de la mer affectent de plus en plus de nombreuses régions. Et pourtant, le taux d'émission de gaz à effet de serre (GES) du Maroc est relativement faible, comparé à celui d'autres pays. En 20162, les émissions totales de GES du Maroc ont atte ...

The consequences of climate change are becoming progressively more visible in Morocco. Changes in rainfall patterns and drought, increases in average temperatures and heatwaves, flooding, and rising sea levels are increasingly affecting several regions. Yet, Morocco has a relatively low greenhouse gas (GHG) emission rate, compared to other countries. In 20162, Morocco’s total GHG emissions reached 86127.7 gigagram of carbon dioxide equivalent (Gg CO2-eq), totaling around 0.2% of glo ...

Lors de la Conférence des Parties à la Convention-cadre des Nations unies sur les changements climatiques (CCNUCC) qui s'est tenue à Paris en 2015, les gouvernements se sont engagés à limiter l'augmentation de la température mondiale à un niveau bien inférieur à 2°C par rapport aux niveaux préindustriels. Ils se sont également engagés à atteindre, dès que possible, un pic de leurs émissions et à parvenir à la neutralité carbone au cours de la seconde moitié du siècle. Pour autant, m ...

During the 2015 Paris Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC), governments pledged to limit the global temperature increase to well below 2°C above pre- industrial levels, to peak emissions as soon as possible, and to achieve carbon neutrality in the second half of the century. Yet, even assuming full implementation of the commitments made by governments in Paris, the global concentration of greenhouse-gas (GHG) emissions will ...

With a population of approximately 200 million, Nigeria accounts for about half of West Africa's population and has one of the largest concentrations of young people in the world. Endowed with abundant natural resources, Nigeria is one of Africa's largest oil exporters, with an estimated 37 billion barrels of proven crude oil reserves, the majority of which are found in the Niger River Delta and offshore in the Bight of Benin, the Gulf of Guinea and the Bight of Bonny. Nigeria also ...

The pandemic is accelerating history, in the sense that it is leading to the speeding up of some recent trends. In the case of globalization, the pandemic will not reverse it, but it will reshape it. Here we take a bird’s eye view of global trade during the pandemic, relate it to previous trends, and guess how global value chain managers and government trade policymakers are likely to react. A Bird’s Eye View of Global Trade during the Pandemic World trade took a deep dive during ...

- There are three possible justifications for central banks to engage with climate change issues: financial risks, macroeconomic impacts, and mitigation/adaptation policies. - Regardless of the extent to which individual central banks take action in each of the three areas, they can no longer ignore climate change. Last year, extreme weather events associated with climate change – floods, violent storms, droughts, and forest fires –occurred on all inhabited continents. In at least ...

This paper is about the basic principles which should guide fertilizer policy for smallholder agriculture in sub-Saharan Africa It is not about detailed country-specific prescriptions on the “how” of policy. This important task should constitute the substance of detailed country studies. The overarching goal here is to use fertilizer to spearhead and sustain an African Green Revolution (GR). In this paper, fertilizer use is not considered as an end in itself, but as a necessary mean ...

“O! WRETCHED MORTALS, OPEN YOUR EYES” Leonardo da Vinci, creator of the ever beautiful and impenetrable Mona Lisa, noted 500 years ago that he realized the importance of water, which is, the artist jotted in his notebooks , “the driving force of all nature”, the vetturale di natura, the vehicle of nature. Da Vinci was not only acclaimed by kings and wealthy nobility like the Florentine Medici’s for his paintings , but the genius, possibly one of the greatest minds and creative pow ...

Earlier this month, the World Resources Institute based in Washington D.C. revealed that 17 countries, home to one-quarter of the world's population, are facing extremely high water stress. Below is an international press review of the global water crisis by Helmut Sorge, former Foreign editor, and Middle East expert for Germany's leading newsmagazine "Der Spiegel", and columnist at the Policy Center for the New South.    “A QUARTER OF THE WORLD IS FACING A LOOMING WATER CRISIS” “ ...
