In a joint report focusing on Iraq, Syria and Yemen, the International Committee of the Red Cross (ICRC) and the Norwegian Red Cross demanded greater assistance, saying the combined effects of climate change and armed conflict create an alarming cocktail of humanitarian woes.

The Climate Funds Update database, which collates information from 27 UN, World Bank and other multilateral funds, listed only 19 single-country projects in Iraq, Syria and Yemen that have been approved for funding as of January 2022, the report said.

It noted the total amount disbursed to date is just $20.6 million -- less than 0.5 percent of the money spent on climate projects worldwide.

"Current climate finance distributions almost entirely exclude the most fragile and unstable places," said the 56-page report.

"It's clear from a humanitarian perspective that this must change," said Anne Bergh, secretary-general of the Norwegian Red Cross.

Grappling with an eight-year civil war, the University of Notre Dame's Global Adaptation Initiative ranks Yemen as one of the region's most climate-vulnerable countries, topped only by Sudan and Afghanistan.

"In Yemen, it is not uncommon for people to flee their homes seeking safety from conflict only to then leave that new location because the land cannot be farmed" due to drought and water scarcity, the ICRC said in a statement.

The United Nations ranks Iraq, still recovering from decades of conflict, as one of five countries most impacted by some effects of climate change including drought.

Syria is also at heightened risk following more than a decade of war that has battered the country's infrastructure.

"Death, injury and destruction are the devastating and well-known effects of armed conflict," ICRC regional director Fabrizio Carboni said in a statement.

"Less well-known are the challenges residents must endure and overcome because of this terrible combination of conflict, climate change and environmental degradation."
