805 million people worldwide suffer from hunger. For the most part, these people live in developing countries. According to the the United Nations Development Program (UNDP), 600 million people could be added to the previous total in 2080 because of climate change. Paradoxically, the main victims of this change are also the least responsible for it.
In just one century, the global temperature rose by an average of 0.75°C. But this trend continues to be on the rise. Climate change has major consequences on water access and agriculture: the decline in agricultural yields, crops destruction by extreme weather events, season shifts and changes, many elements impacting food safety and populations. Implementing adaptation policies is therefore an absolute necessity.
Malnutrition and lack of access to drinkable water are not the only health issues caused by climate change. Heat waves are going to become more and more recurrent, increasing the risks of death, especially among older populations. Some vector-borne diseases like malaria or dengue will spread. Allergies will also become more frequent and more potent because of the spread of allergen plant species and atmospheric pollution.
Developing and industrialized countries will all be impacted but in different ways. The only sure thing is that vulnerable populations will become even more vulnerable. Despite having local specificities, the climate change issue needs a global answer. The climate conference (COP 21) in Paris in December will be the perfect place to find one.
