This research initiative in Arunachal Pradesh is a build-up on the first phase of studies in the north-east that led to the publication of an earlier UNESO-sponsored MAB book series, entitled "shifting agriculture and sustainable development: an interdisciplinary study from North-East India". Emphasising upon linking knowledge systems, this volume expands up on a community participatory developmental paradigm based on hybrid technology interventions for ecological conservation linked with development of the region.

The present investigation deals with the influence of heavy metals, Zinc, Cobalt and Nickel on chlorophyll content of algae Pithophora aequalis.
