Global warming and the future of food

While one in eight people in the world is threatened by a deadly heat wave in South Asia which has already claimed the lives of nearly 100 people, it is time to recognize that the climate crisis is a health crisis.

It is not an isolated problem. In South Africarecent floods claimed the lives of more than 400 people, across the sahel violence and insecurity increase as people struggle with hunger, malnutrition and other factors exacerbated exponentially by climate change, and in place as Colombiahealth and food security are at risk as floods displace communities and trigger disease outbreaks.

This is the most pressing health and humanitarian challenge of the 21st century. A quarter of a million people are expected to die each year from climate change between 2030 and 2050 if we do nothing about it, according to the World Health Organization (WHO).

Climate change affects the social and environmental determinants of health – clean air, safe drinking water, sufficient food and safe shelter. According to recent IPCC report on climate changeclimate change has adverse effects on human health ranging from mortality from extreme events, morbidity from rising temperatures and heat waves, malnutrition and susceptibility to disease.

And for the first time ever, the IPCC report includes mental health as a key area affected by the climate crisis, noting that climate change has adversely affected the physical and mental health of people around the world.

People are losing their homes and loved ones as conflicts erupt over scarce resources in places like the Lake Chad Basin, and they dread the stress as we face the prolonged impacts of COVID-19 and the specter of other zoonotic pathogens that will increase as heat and environmental damage push animals out of their traditional areas, according to Harvard.

And even as countries and communities emerge from the COVID-19 crisis, it is clear that the pandemic has reinforced pre-existing structural inequalities, heightened systemic challenges and risks, and threatens to reverse hard-won progress in achieving the Sustainable Development Goals (SDGs) .

Climate change is expected to further increase the risks. We are already seeing “irreversible” damage from climate change. According to the IPCC report, more than 3 billion people – nearly half of the world’s population – live in “settings that are highly vulnerable to climate change”. And the direct costs of climate change to the health system – not counting health-determining sectors such as agriculture, water and sanitation – are estimated at between $2 billion and $4 billion per year by the WHO. .

Rethinking climate and health

Adaptation to climate change will be one of the main highlights of the Climate Talks in Egypt. World leaders have the opportunity to connect the dots between health, food security, livelihoods, sustainable economic development and climate action as we come together to accelerate the ambition of Nationally Determined Contributions to the Paris Agreement and sprinting to achieve the lofty goals set out in the 2030 Agenda for Sustainable Development.

Most nationally determined contributions have identified health as a priority concern. At COP-26 on 50 countries have pledged to build climate-resilient, low-carbon health systems. These include 47 countries, accounting for more than a third of global healthcare emissions. Fourteen countries have also set a target date to achieve net zero carbon emissions in their healthcare system before 2050.

There are a number of entry points that can help countries achieve these goals. Key opportunities arise from adaptation interventions that contribute to food and water security, climate-informed health planning that can feed into national adaptation plans, early warning systems for climate-sensitive infectious diseases capacity building of health facilities to develop protocols and prepare for changing health needs resulting from the climate crisis, public health education campaigns and community-level investments in facilities water and sanitation and other infrastructure that prevents the spread of disease.

When you think about it as a whole, the climate and health crisis is surprisingly complex. In places like Egypt, people need air conditioning units just to survive over 120 degree days. But more alternating current means more greenhouse gases. We therefore also need to rethink economic development, incentives for renewable energy and the reduction of hydro-chloro-fluorocarbons and other pollutants that literally poison our planet.

We must also rethink climate resilience in our cities, on the farm and in the marketplace, redefining our approach to trade and economic development as we adapt to the new challenges of the 21st century.

Management of climate-health actions

The good news is that we are making progress.

With funding from the Global Environment Facility Special Climate Change Fundthe United Nations Development Program (UNDP) and WHO have helped local governments lead climate change adaptation efforts to protect Human health in Barbados, Bhutan, China, Fiji, Jordan, Kenya and Uzbekistan.

In Barbados, community public health campaigns have promoted the safe use of wastewater. In Bhutan, the government has improved its ability to predict climate-sensitive infectious diseases. And in China, three pilot cities have set up a heat-health alert system.

With GEF funding, UNDP partners with WHO to build resilient health systems in Asian Least Developed Countriesincluding Bangladesh, Cambodia, Lao PDR, Myanmar, Nepal, Timor-Leste and Small Island Developing States such as Kiribati, the Solomon Islands, Tuvalu and Vanuatu. Among the various outcomes, the programs will advance climate-informed health planning and early warning systems, build the capacity of health facilities, implement public health campaigns, and support localized community actions directed at the crisis. climate and health.

There’s a bigger picture here. Ultimately, projects designed to achieve food and water security, advance ecosystem-based adaptation, or improve livelihoods will help us solve these interconnected problems. In partnership with governments, donors, the private sector, civil society and other key stakeholders, the current UNDP program climate change adaptation portfolio is intended to benefit 126 million people with $1.6 billion in investments from vertical funds and bilateral donors, as well as an additional $3.8 billion from partners.

This good start, but far from the 20 to 40 billion US dollars of annual expenditure for adaptation to climate change called for at the Glasgow climate talks.

Taking a system-wide approach, embracing new technologies and ways of working, engaging with the private sector and activating locally-led climate action is essential if we are to address to this crisis.

Millions of lives are at stake. It’s time to step up and make climate action – and climate-health action – a global priority. It is our investment in planet Earth, our investment in future generations, our investment in a better world.
