Climate Crisis: Human-Induced Factors Amplify Drought in Syria, Iraq, and Iran

 Climate Crisis: Human-Induced Factors Amplify Drought in Syria, Iraq, and Iran

In a groundbreaking study conducted by scientists from Iran, the Netherlands, the UK, and the US, alarming revelations have surfaced regarding the escalating severity of drought in Syria, Iraq, and Iran. The research, utilizing the Standardized Precipitation Evapotranspiration Index (SPEI), attributes this crisis to a combination of human-induced climate change and socio-economic water stressors, creating a complex and pressing threat to the affected regions.

Understanding the Drought Dynamics

The arid region heavily relies on rain-fed agriculture, notably wheat farming and livestock, making the population particularly vulnerable. The 3-year drought, ranking as the second worst on record, unfolds against a backdrop of socio-economic challenges, including the ongoing conflict in Ukraine impacting energy and food prices, along with regional conflicts and political unrest.

Assessment of Agricultural Drought

The research focuses on agricultural drought, considering both rainfall and evaporation estimates. The SPEI, indicating the difference between rainfall and potential evapotranspiration, serves as a key variable. Over the 36 months leading up to June 2023, the study portrays a concerning trend, highlighting extreme and exceptional agricultural drought in the fertile crescent around the Euphrates and Tigris rivers and large parts of Iran.

Human-Induced Climate Change Impact

The study not only identifies the severity of the current drought but delves into the impact of human-induced climate change. The likelihood of such a drought occurring has increased significantly, with the intensity reaching a point where, in a 1.2°C cooler world, it would not be classified as a drought at all. The escalating temperatures, primarily driven by fossil fuel burning, emerge as the key driver of drought severity.

Urgent Calls for Action

The findings underscore the vulnerability of the affected regions, compounded by limited technical capacity, rapid urbanization, and regional instability. The humanitarian crisis demands urgent efforts for more effective water management strategies, interdisciplinary response, and regional cooperation involving farmers and stakeholders in planning. Despite 'low confidence' in IPCC projections, the study emphasizes the pressing need to address increasing water stress resulting from human-induced climate change and systemic factors.

Future Implications

Unless swift action is taken to curb fossil fuel burning, such drought events are predicted to become even more common in the future. A world 2°C warmer than preindustrial levels could witness exceptional droughts, marking the worst category possible. The current high levels of water stress in the region, compounded by various systemic factors, further emphasize the need for immediate action.
