The impact of global drought on biodiversity is an increasingly urgent issue of concern. Drought, characterized by a sustained lack of significant rainfall, can trigger severe ecosystem damage. Various species of flora and fauna are under pressure due to the reduction of vital water resources. One of the main impacts of drought is decreasing habitat quality. When the land becomes dry, the vegetation that supports the lives of various species begins to die. This has direct implications for fauna that depend on plants as a source of food and shelter. For example, forest loss due to drought results in the loss of wildlife species, including various mammals and birds, which play an important role in maintaining ecosystem balance. Apart from that, drought also worsens soil conditions. The erosion process will increase due to the absence of vegetation, making the soil more vulnerable to damage. This results in reduced soil fertility, which will affect agriculture and biodiversity as a whole. Degraded soil is unable to support the life of various microorganisms that are important for ecosystem regeneration. Droughts have a significant impact on water quality, especially in river and lake watersheds. A decrease in water volume results in an increase in pollutant concentrations, which are harmful to aquatic organisms. Fish and invertebrate species that are sensitive to changes in water quality are experiencing drastic population declines. This condition disrupts food webs in aquatic ecosystems, which can cause wider impacts on various species that depend on the same food sources. Adaptation of species to drought conditions is also a challenge. Although some species have the ability to adapt to dry conditions, rapid rates of change can exceed their ability to adapt. This leads to the risk of extinction for many species, especially those with narrow or specific habitats. Climate change is a major factor exacerbating drought. Rising global temperatures reduce rainfall and increase evaporation. Species that are unable to adapt quickly will face serious threats. Therefore, raising awareness about the impacts of drought and strengthening conservation efforts is critical to protecting biodiversity. Ecosystem services are also affected by drought. A decline in species diversity can disrupt important ecosystem processes, such as pollination and nutrient cycling. The connection between species and their environment makes each species play a vital role in the sustainability of the ecosystem. With the loss of biodiversity, the ecosystem’s ability to provide these services will decline. Overall, the impact of global drought on biodiversity is significant and complex. Collaborative efforts at local and global levels are needed to address these challenges. Further research and the development of effective adaptation strategies will be the key to maintaining sustainable biodiversity amidst the increasing threat of drought.
