A comparative study on livelihood of undisturbed forest village and relocated village is presented. Analysis revealed that agriculture as a sole occupation could not provide livelihood to the tribal. The relocated village (Tetu in Amravati district) was settled on agriculturally poor soils. Denial of access for NTFP collection and poor agricultural productivity were the main factors that led to impoverishment of villagers. Similarly, villages in Gondia district situated in similar domain/settings had relatively better soils, but could not support the population adequately. However, permission to collect NTFP made the difference. It was also observed that apart from modernising agriculture, it is essential to impart skills to the villagers to derive income from sources other than agriculture (e.g. pisciculture, poultry) before displacing them. It was also apparent that the relocation on fringes of forest with poor soils could force tribal to utilize forest resources without heed to conservation. The policy for relocation thus needs to be formulated based on the findings.Keywords

Antarctic ice core records have provided unprecedented information on past climatic changes and forcing factors on decadal to millennial timescales. The glaciochemical and stable isotope records of a shallow ice core from the coastal Dronning Maud Land (East Antarctica) were used here to reconstruct the coastal Antarctic environmental variability during the past ~470 years. Sea salt ion data indicate a significant additional contribution of chloride ions compared to sea water values, possibly through atmospheric scavenging. The nitrate (NO3 -) profile exhibit significant temporal shifts than that of the sulphate (SO4 2-), with a major shift around 1750 AD. The changes in NO3 - record are synchronous with the proxy record of solar activity ( 10Be profile from a South Pole ice core), suggesting enhanced NO3 - values during periods of reduced solar activity like the Dalton Minimum (~1790-1830 AD) and Maunder Minimum (~1640- 1710 AD). The δ18O records reveal that the more negative V values were coeval with several events of increased NO3 - concentrations, suggesting enhanced preservation of NO3 - during periods of reduced air temperatures. The δ18O and δD records of the core also suggest significant short-term and long-tem variability with more negative values indicating relatively lower air temperatures prior to 1715 AD. The δ18O records also revealed a significant warming of 2.7°C for the past 470 years, with a warming of ~0.6°C per century.Keywords
