Take urgent action to combat climate change and its impacts

Climate change is now affecting every country on every continent. It is disrupting national economies and affecting lives, costing people, communities and countries dearly today and even more tomorrow. Weather patterns are changing, sea levels are rising, weather events are becoming more extreme and greenhouse gas emissions are now at their highest levels in history. Without action, the world’s average surface temperature is likely to surpass 3 degrees centigrade this century. The poorest and most vulnerable people are being affected the most.Affordable, scalable solutions are now available to enable countries to leapfrog to cleaner, more resilient economies. The pace of change is quickening as more people are turning to renewable energy and a range of other measures that will reduce emissions and increase adaptation efforts. Climate change, however, is a global challenge that does not respect national borders. It is an issue that requires solutions that need to be coordinated at the international level to help developing countries move toward a low-carbon economy.To strengthen the global response to the threat of climate change, countries adopted the Paris Agreement at the COP21 in Paris, which went into force in November of 2016. In the agreement, all countries agreed to work to limit global temperature rise to well below 2 degrees centigrade. As of April 2018, 175 parties had ratified the Paris Agreement and 10 developing countries had submitted their first iteration of their national adaptation plans for responding to climate change.

Où en est la Tunisie concernant l’ODD #13

La Tunisie est considérée parmi les pays méditerranéens les plus exposés aux changements climatiques. A dominance aride et semi-aride (près de 96% de son espace géographique), elle subit des périodes de sècheresses récurrentes et une grande variabilité spatiale et interannuelle des précipitations. la Tunisie serait confrontée à la hausse des phénomènes climatiques extrêmes (inondations, sécheresses, désertification, tempêtes en mer et vent violents, orages foudres et grêles, feux de forêts, etc.) qui engendreraient des impacts néfastes majeurs sur les écosystèmes et les ressources naturelles, sur la santé et sur les activités économiques.
