“Tackling climate change in fact represents one of the greatest opportunities to benefit human health for generations to come”, according to the co-chair of the Commission on Health and Climate, Professor Anthony Costello, director University College London Institute for Global Health. The Commission, a group of scientists convened by The Lancet journal, has published its second report on 22 June 2015.
The study brings together data on climate and population trends and quantifies the future global health impacts of climate change. It looks at both direct impacts of extreme weather like heat, floods and storms, and adverse indirect effects of food insecurity, poor air quality or even displacement. For instance, three times more people will be exposed to drought by the end of the century and four times more to extreme rainfall. In many areas, this implies no less than reversing development gains. Urgent action on mitigating climate change and preparing for its health-related challenges is needed: actual carbon emission rates have been even higher than in the worst-case scenario of the previous Lancet study (2009) on health and climate.
Major health co-benefits of climate action should encourage policy-makers to act more decisively. Fortunately, there is increasing momentum. For example, the intergovernmental Climate and Clean Air Coalition to Reduce Short Lived Climate Pollutants (CCAC), initiated in 2012, emphasises that mitigating methane, black carbon, and HFCs can help avoid two million premature deaths every year. In fact, air pollution was proclaimed one of “the leading avoidable causes of disease and death globally” by the World Health Assembly in a resolution of 26 May 2015, as every year 8 million deaths can be attributed to polluted air exposure indoor and outdoor.

In an increasingly urbanised world, global resilience cannot be achieved without cities. Separating a local from a national or international sustainability issue is increasingly difficult – be it climate change, migration, or economic development.
Climate diplomacy needs to release itself from the shackles of ‘systemic’ politics in order to achieve a climate agenda that is driven by human security interests, including equity and justice, and strengthen climate change initiatives at local, national and regional levels, in order to bridge the gap caused by the slow pace of progress at the international level.
Leaving No One Behind is the mantra of the 2019 UN-Water campaign. Foreign policy agendas of countries should apply the principle and integrate the voices of the most marginalised into the decision-making process, argues Dhanasree Jayaram.
Water is a matter of survival and plays a critical role in social, economic and environmental activities as well. With a rise in global demand for water, water crises have consistently featured among the World Economic Forum’s top global impact risks. Water insecurity, i.e., the lack of water availability for basic human needs and socio-economic development, undermines billions of livelihoods and poses significant risks for peace and prosperity by thwarting progress and fuelling displacement and conflict.
