Abstract

nClimate change remains one of the most important phenomena affecting the geographical distribution and movement patterns of vector-borne diseases. In South Asia—characterized by high population density, rich biodiversity, and sharp climatic differences—there is growing evidence of the relationship between increasing temperatures and erratic precipitation along with the behavior of insect vectors. This research aims to evaluate the effects of climate environmental changes on the distribution and seasonal activity of important vector insects like Aedes aegypti, Anopheles stephensi, Phlebotomus argentipes, and tick species. A systematic review of epidemiological literature along with climate data and vector monitoring data from 2010 to 2024 were analyzed using spatial analysis through geoinformatics. There is striking contemporaneous evidence of both longitudinal and vertical shifts in the habitats of some vectors and now many more disease-carrying species are being reported from regions which were earlier considered non-endemic like the Himalayan foothills and the semiarid plains. Much of this newly affected documented areas are gradually facing increased cases of dengue, malaria and leishmaniasis. Most of the pathogen incubation periods in the vectors has reduced due to the rise in temperatures while the prolonged precipitation and humidity levels have aided in higher breeding and better survival of the vectors. The study emphasizes the importance of focused climate change public health strategies, responsive multisectorial vector monitoring, and geo-specific anticipatory frameworks including preemptive climate adaptable measures aimed at the vulnerable population groups. It draws attention towards the need for transnational collaboration, enhanced infrastructure, and public health information systems to address the rising danger associated with climate-sensitive vector-borne diseases in South Asia. These observations will help guide policymakers, public health experts, and researchers formulate effective plans for long-term preventive measures.nn
