Links between water and conflict seem to crop up everywhere one looks these days. The Horn of Africa will soon face a sixth consecutive failed rainy season in 2023—its worst drought on record. Not only is this drought a consequence of global climate change, but it has also led to widespread food shortages and local civil conflicts. And over the past year in Ukraine, Russian troops have directly damaged that nation’s already vulnerable water systems, including pipelines, pumping stations, and treatment facilities. These repeated attacks on water infrastructure have not only undermined local livelihoods in Ukraine, but they have also polluted surface waters and threatened biodiversity.

Already facing water stress, much of Latin America (such as the western slopes of the Andes and the dry corridor of Central America) is projected to experience intensified periods of drought in the coming decades, further complicating development efforts in the region. At the same time, heavy floods are the most common natural disaster in the region, disrupting life for countless people. According to the World Bank, in Latin America and the Caribbean alone roughly $14 billion per year is required to meet the 2030 water and sanitation targets of the United Nations Sustainable Development Goals. Typically, investments at this scale have been made by governments and large firms that invest in traditional infrastructure such as dams. But with ever-growing development needs and increased understanding of the impacts of climate change, Nature-based Solutions (NBS) are gaining momentum as a new way of incorporating environmental considerations into development responses.

As the climate crisis continues to worsen, climate finance remains a fraction of what is needed. The Climate Policy Initiative estimates that $579 billion was spent on average on climate finance in 2017/18. This includes domestic and international investment from both the public and private sectors towards climate mitigation and adaptation actions. Of this amount, only $30 billion—five percent—was allocated for climate adaptation. This amount stands in stark contrast to $180 billion, which the Global Commission on Adaptation estimates is needed every year to build resilience to current and future climate impacts. This catastrophic funding gap is intensifying climate security threats and elevating the vulnerability of people across the world, particularly in coastal urban centers.

“It is in Brazil’s interest to climate-proof the nation,” said Wilson Center Senior Fellow Sherri Goodman during a recent International Military Council on Climate and Security (IMCCS) event. Referencing a new IMCCS  report, Climate and Security in Brazil, Goodman, who is also Secretary General for the IMCCS, said that Brazilian leaders ought to develop counter-deforestation and climate plans as critical elements of the national security agenda.

Climate change will upend the 21^st century world order. It will redefine how we live and work, and change the systems of production, trade, economics, and finance. Even now, in the midst of a global pandemic, it is clear that climate change will be the defining issue of this century. In fact, COVID-19 has only underscored the inadequacy of our responses to global crises and heightened the urgency of this call to action. 21^st century diplomacy will have to raise climate ambition, shape the transformative systems change needed, and promote and facilitate new modes of multilateral collaboration.

“The gender perspective highlights how pre-existing inequalities and vulnerabilities are exacerbated in conflict and in disasters,” said Susanne Kozak, a doctoral candidate at Monash University at a recent event hosted by the Environmental Peacebuilding Association and University of Melbourne’s Faculty of Science.

When Farhad Ahma returned to his native country last year on a work trip, his first thought was of his small daughter back home. The air around him was so thick with pollution, he couldn’t imagine she would survive the climate in this region of northeastern Syria. Ahma himself struggled to breathe almost as soon as he arrived, nauseated by the heavy smell within a couple hours. He was born and raised nearby, in a city called Qamishli, but he had lived in Berlin for some time now. Returning was a shock to his system.

Some older Wuhan residents still talk about paddling across the city in their boats, traversing the 100-plus lakes that were once connected by a network of canals. This once-leisurely activity takes on different meaning today as citizens navigate some of the worst floods in decades. Hubei Province, where Wuhan is the capital, is among the 27 central and southern Chinese provinces affected by floods that have caused CNY 86 billion (USD $12.3 billion) in nationwide economic losses in June and July of this year.
