Abstract

The Holocene epoch, all over the world, has witnessed exceptional climate and sea level changes. Although the south-west coast of India has a fairly thick deposit of Holocene sediments of 50-60 m in the South Kerala Sedimentary Basin (SKSB) and its adjoining coastal lowlands (see inset in Fig. 13.1), not much focus has been given to unfold its palaeo-climatic and palaeo-environmental potential till the beginning of the present century (Joseph and Thrivikramji, 2002; Nair and Padmalal, 2003; Nair et al., 2006; Kumaran et al., 2005; Limaye et al., 2007). South-west coast of India was affected significantly by sea level and climate changes which in turn had a strong bearing on human settlements/migration in the area. Recent advances in archaeological investigations in the Pattanam-Kodungallur stretch in Central Kerala (Shajan et al., 2004; Abraham, 2006) gave indications of shifts in human settlements in accordance with changing climates and/or sea level positions.
