Presented by Engineer Noor Amir Abstract Climate change is one of the most significant environmental challenges facing Iraq, given the rising temperatures, declining rainfall, and increasing frequency of droughts and dust storms, in addition to worsening water scarcity and degradation of agricultural lands. These changes directly affect water resources, food security, human health, biodiversity, and economic development. This article aims to highlight the major manifestations of climate change in Iraq, analyze its environmental, social, and economic impacts, and review a range of sustainable solutions that could help mitigate its effects and strengthen society’s capacity to adapt. The article emphasizes the importance of integrated water resources management, the development of sustainable agriculture, the expansion of renewable energy use, the protection of ecosystems, the strengthening of environmental legislation, and regional cooperation. 1. Introduction The world is experiencing rapid climate change associated with rising global average temperatures and increasing concentrations of greenhouse gases in the atmosphere as a result of human activities, particularly the burning of fossil fuels, deforestation, and changes in land use. These changes disrupt climatic and hydrological systems and affect the distribution of natural resources and the stability of ecosystems. Iraq is considered one of the countries highly vulnerable to climate-related risks in the Middle East due to its arid and semi-arid climate, its heavy dependence on surface water resources, and the sensitivity of its agricultural sector to changes in temperature and rainfall. Furthermore, pressures resulting from population growth, poor resource management, and deteriorating water infrastructure make addressing these challenges increasingly difficult. Therefore, addressing climate change in Iraq requires a shift from temporary solutions toward long-term strategies based on scientific principles. These strategies should combine adaptation to existing impacts with the mitigation of greenhouse gas emissions within a sustainable development framework. 2. Manifestations of Climate Change in Iraq Climate change in Iraq is evident through a range of environmental phenomena whose effects overlap and influence the stability of natural resources and economic activities. Reports from the World Bank and the United Nations Development Programme indicate that rising temperatures, declining rainfall, water scarcity, dust storms, and soil salinization represent major challenges to sustainable development in the country. 2.1 Rising Temperatures Rising temperatures are among the most prominent manifestations of climate change in Iraq. They increase demand for water and energy and raise evaporation rates from rivers, reservoirs, and soil. High temperatures also increase health risks associated with heat stress and affect the productivity of workers in outdoor sectors, particularly agriculture and construction. Recurring heatwaves also lead to increased electricity consumption for cooling, placing additional pressure on the power supply system and highlighting the need to improve energy production and consumption efficiency. 2.2 Water Scarcity and Declining Water Resources The water crisis represents one of the most serious environmental challenges facing Iraq. It results from the combined effects of climate change and other factors, including declining river inflows, changes in the management of transboundary water resources, population growth, and increasing agricultural and domestic water demand. Low rainfall and increased evaporation reduce water availability in some areas, while poor irrigation network management and excessive withdrawals from water resources further intensify the crisis. The World Bank has warned of a widening gap between water supply and demand in Iraq unless appropriate reform measures are implemented. 2.3 Drought, Desertification, and Land Degradation Recurring droughts and rising temperatures reduce soil moisture and vegetation cover, making land more vulnerable to erosion and degradation. These effects are particularly evident in agricultural areas that depend on rainfall or limited irrigation resources. Overgrazing, vegetation removal, and poor soil and water management can also accelerate desertification. Consequently, soil fertility declines, agricultural productivity decreases, and economic pressures on rural communities intensify. 2.4 Dust Storms and Environmental Pollution Dry conditions, the degradation of vegetation cover, and exposed soil increase the susceptibility of certain areas to generating dust and airborne particles carried by the wind.
