Rapid population growth, urbanisation, migration and economic and social activities have local, regional impacts on climate. One of the major human influence in the temperature trends is the land use/landcover changes and its radiative forcing’s. Kerala have experienced a drastic transition from a rural entity to a ‘rurban’ entity within a short span of time. This has caused apparent micro-climatic changes measurable only by time series analysis of constituent effects on the rurban environment. Such effects are measurable through time series analysis of – effects on permanent vegetation; ambient temperature; and rainfall amounts. Such a study shall focus on the known urban areas and its immediate sprawl areas. In Kerala, these effects may primarily be measurable in Thiruvananthapuram, Kochi and Kozhikode cities, given the growth of these cities in the last 25 years.
