Global drought has become one of the most serious environmental challenges in the era of climate change. This phenomenon is increasingly widespread, affecting ecosystems, agriculture and human life throughout the world. Data shows that rising global temperatures and erratic rainfall patterns contribute significantly to the increase in the frequency and intensity of droughts. One of the main causes of drought is climate change, which results in faster evaporation of water and reduced groundwater reserves. In this context, land degradation also plays a major role, where unsustainable agricultural practices damage the soil structure, reducing its ability to store water. Excessive use of water in irrigation further worsens the condition, considering that many regions depend on limited water sources. The socio-economic impact of drought cannot be underestimated. The shortage of clean water is triggered by an increase in water demand for consumption and agriculture, causing conflicts between water users, especially in densely populated areas. Public health is also threatened because drought often causes the spread of disease due to poor sanitation. Agriculture is the sector most vulnerable to the impacts of drought. Crops that rely on irrigation suffer significant losses, and farmers are often forced to switch from food crops to more drought-resistant crops, which does not always guarantee food security. The instability of agricultural product prices due to supply shortages further exacerbates this situation. Mitigation and adaptation initiatives are needed to overcome the global drought challenge. Modern irrigation technology, such as drip irrigation systems, can help optimize water use. Additionally, sustainable water management practices, such as water conservation and rainwater storage techniques, are important to implement in various communities, especially those prone to drought. Public education regarding the importance of efficient water use is also very important. Water conservation awareness campaigns can teach individuals to minimize waste and change daily habits. Involving local communities in water resource management can create solutions that are more appropriate to the local social and cultural context. At the policy level, governments around the world need to develop programs and regulations that support sustainable management of water resources. International cooperation is also very necessary, considering that many areas experience cross-border impacts. In addition, investment in water research and innovation to find new solutions to the drought problem is a strategic step. Meanwhile, global public awareness of the increasing impacts of drought can mobilize collective action. Social media and digital platforms can be used to disseminate information about best practices for dealing with drought. By raising awareness and encouraging action at local, regional and global levels, the global drought challenge can be met more effectively. Ultimately, the integration of ecosystem-based approaches is key to building resilience to drought. By restoring ecosystem functions, such as reforestation and wetland restoration, the environment can better adapt to climate change. Through cross-sector collaboration and creating sustainable solutions, the world can tackle this increasingly urgent drought challenge.
