Impact of economic drivers on mangroves of Indian Sundarbans: an exploration of missing links

Export of shrimps and prawns using intensive cultivation in the Sundarban area of Indian Bengal had a negative impact on mangrove forests in 1980s. Land conversions from agricultural use and mangrove forest to shrimp ponds are significant. The impact of changing economic factors such as trade on mangrove forests is evident but as yet this link is not clearly understood by decision-makers. In this context, this study analyses the impact of economic driver on land use changes by combining socio-economic data (economic variables) and satellite data (land use change). Using the panel data method for 1986–2004 in eight administrative units of the Sundarbans area, the study identifies relative return and productivity of labour for various types of land use together with population density as the major drivers of land use change. Identification of these drivers would help to design an effective response policy for management of this UNESCO Heritage site. Copyright Springer Science+Business Media B.V. 2012
