Le changement climatique a déjà des répercussions concrètes et quantifiables sur la santé humaine, qui devraient aller en s’aggravant. Particulièrement exposés aux aléas du climat et moins capables de s’y adapter à cause de systèmes de santé et d’infrastructures défaillants, les pays à revenu faible et intermédiaire sont les plus durement touchés. Heureusement, cela fait des décennies que les experts s’intéressent aux impacts cumulés du changement climatique sur la santé, de sorte que nous comprenons de mieux en mieux les enjeux.

À cause notamment de ses effets délétères sur la santé, le dérèglement climatique pourrait replonger dans la pauvreté plus de 100 millions de personnes à l’horizon 2030. Les agents polluants associés aux émissions de carbone sont déjà responsables de plus de 7 millions de décès prématurés par an. D’ici 2030, ce sont 7,5 millions d’enfants supplémentaires qui risquent de présenter un retard de croissance, dont 4 millions sous une forme sévère (soit une augmentation de 4 %). L’Organisation mondiale de la santé (OMS) estime qu’avec le changement climatique, le nombre d’enfants souffrant de retards de croissance devrait passer à 10 millions en 2050. En Afrique, le renchérissement des denrées alimentaires lié au changement climatique pourrait atteindre 12 % en 2030 et jusqu’à 70 % en 2080 — ce qui porterait un coup brutal aux pays où la nourriture représente plus de 60 % des dépenses des ménages les plus démunis. Quant aux coûts directs pour la santé (hors dépenses dans les secteurs qui ont un impact sur la santé, comme l’agriculture, l’eau et l’assainissement), ils se situeraient dans une fourchette de 2 à 4 milliards de dollars par an d’ici 2030.
 
Le problème, c’est que 15 % seulement des pays qui se sont dotés de plans d’action contre le changement climatique y ont intégré un volet sanitaire. Conscient de cette lacune et face à l’appel grandissant des chercheurs et des agents sur le terrain, le Groupe de la Banque mondiale a élaboré un programme pour y remédier. 

Connecting Climate Change and Health for Better Development

Climate change is already having real, measurable impacts on human health, and those impacts are expected to grow. Low- and middle-income countries are seeing the worst effects as they are most vulnerable to climate shifts and least able to adapt given weak health systems and poor infrastructure. The good news is that the cumulative impacts of climate change on health have been extensively discussed for decades and understanding is growing.

Pandemics will strike but countries' preparedness is less certain

Turkey is a transcontinental country, with territory contiguously spanning two continents. It is bordered by eight countries and is circled by sea on three sides. The international airport in Istanbul is the 10th busiest airport in the world, and last year, in 2016, more than 60 million passengers went through it. Of these, two-thirds were international passengers. Yes, Turkey is very vulnerable to disease outbreaks. Indeed, all countries are.

World No Tobacco Day 2017: Why Does It Matter?

Patricio V. Marquez's picture


"Sugar, rum, and tobacco, are commodities which are nowhere necessaries of life, [but] which are ... objects of almost universal consumption, and which are therefore extremely proper subjects of taxation."

-    Adam Smith, An Inquiry into the Nature and Causes of the Wealth of Nations (1776)


World No Tobacco Day 2017 focuses on the links between tobacco use, tobacco control, and sustainable development. Does this mean that tobacco use is more than a public health issue?  The answer is an emphatic yes, rooted in robust scientific evidence accumulated over the past five decades and country experiences worldwide. Let me explain.

Statement on appointment of Dr. Tedros Adhanom Ghebreyesus

On behalf of the World Bank, I extend our very warm congratulations to Dr. Tedros Adhanom Ghebreyesus on his election as Director-General of the World Health Organization.  He brings a wealth of expertise and experience that will help steer WHO to have even greater impact. We look forward to strengthening our collaboration with WHO under the leadership of Dr.Tedros in our common pursuit of supporting countries to accelerate progress towards universal health coverage and to improve their preparedness to manage epidemic threats.
        

How a new eLearning course will help improve countries’ civil registration and vital statistics systems

Civil registration and vital statistics systems enable parents to certify
children at birth. A birth certificate provides proof of age, which enables
access to essential services (e.g., health care, education, welfare grants) and
protects against child marriage and child labor.

For some people in low- and middle-income countries, opening a bank account, taking out a loan, obtaining a driver’s license, or sending their children to school is out of reach because they don’t have official documents that prove their legal identity. Why do some people lack birth certificates, marriage certificates, family members’ death certificates, and other documentation?

Financing pandemic preparedness: from analysis to recommendations

In my blog in February I described the rationale behind the creation of the International Working Group on Financing Preparedness (“IWG”), which is focused on how to ensure sustainable funding for the first line of defence against pandemics – prevention, identification and containment of infectious disease outbreaks at a national level. The IWG had its second face-to –face meeting earlier this month in London at Wellcome Trust. The goal of this meeting was to review the analytical work that had taken place over the last couple of months and debate a draft set of recommendations. Since that meeting we have been refining these recommendations with a view to presenting them in draft form to the UN Secretary General’s Global Health Crisis taskforce on May 1 and launching the full report at the World Health Assembly on May 25.

Financing the ‘last mile’ in global polio eradication

Thirty years ago, polio affected nearly 350,000 people per year across 125 countries. Today, the poliovirus is circulating in only two countries, Afghanistan and Pakistan, where five new cases have been reported so far in 2017. But progress to eliminate polio in the region has been difficult, particularly in North-West Pakistan, an area affected by deadly flooding, ongoing conflict, and attacks against vaccine health workers.

Why nutrition is a smart development investment

“If breastfeeding did not already exist, someone who invented it today would deserve a dual Nobel Prize in medicine and economics.” - World Bank Vice President of Human Development, Keith Hansen


This is a sentiment long-shared by many of us in the nutrition community and as the global movement in nutrition grows, so does our body of evidence supporting how powerful nutrition interventions are for individuals and for societies.

On World Health Day, why I'm choosing to talk about depression

This year’s World Health Day carries a particular significance for me and for many others. The theme, “Depression: Let’s Talk,” shines a light upon a problem that oftentimes remains hidden in a dark corner of our minds, trapping us in a painful agony of sadness, loss of interest, and fear.
