India has contributed a lot to this process in international negotiations. However now, the mechanism needs to be implemented at national, state and local levels. Country should be ready with national strategy and action plan and like various other countries pilot projects could be started in different parts of the country to draw lessons for full-fledged implementation of REDD+. Deforestation is not much of the problem in the country. So focused efforts should be made for addressing the drivers of degradation and for conservation and sustainable management of forests in the country. Enough potential exists for enhancement of forest carbon stocks in various kinds of forests, in trees outside forests in both urban and rural landscapes, and in coastal areas. This needs to be harnessed with the help of a huge network of JFM communities in the country. India has developed tremendous capabilities in use of remote sensing, which can be utilized for development of reference levels and carrying out measurement, reporting and verification of carbon stocks. However, capacity needs to be built at state and community levels for mainstreaming REDD+ at all levels in the country.

It may alter the distribution and quality of natural resources. Considering the vulnerabilities of forests and irreversible impacts of climate change on forests, long term planning for forest conservation and management is the urgent need of the hour to ensure and maintain the long-term mitigation potential of forests. In this study multi-disciplinary literature review, interviews with researchers in a variety of related fields, and consultation meetings with selected practitioners at the national, regional, and local levels were conducted. The findings of study highlighted the current status of knowledge, strengths, gaps and constraints in research pertaining to climate change adaptation and mitigation aspects of forests in India.

Forestry sector in developing countries is recognized as one of the largest and low cost mitigation options to address climate change. The present study was conducted to assess the multi-temporal biomass carbon mitigation in the temperate forests of western Himalaya using satellite (Landsat MSS, TM, ETM?) and forest inventory data. Forest type density mapping was done through on-screen visual interpretation of satellite data. After conducting preliminary survey in 2009, 45 quadrats (0.1 ha) were laid in six forest types for collecting field inventory data viz., diameter at breast height, tree height, slope and aspect. Biomass carbon (t ha-1) was estimated for different forest types with different crown densities (open with 10-40% crown density and closed with [40%) using recommended regression equations, ratios and factors. A decreasing trend of carbon (145.13-134.87 mt) was observed over the period of time. Temporal biomass carbon dynamics was analyzed for REDD? opportunities. The temporal variation of carbon observed was found to be more useful for claiming benefits under negative options (deforestation and forest degradation) of REDD?. The study doesn't take actual conversions to CO 2 into account. However, the findings are useful in establishing baseline emissions through temporal carbon losses. Further, the study helps in identification of location specific socioeconomic drivers of losses that can be used for appropriate mitigation interventions.

Eucalyptus tereticornis (Mysore Gum) is most widely planted species in India. In the present paper an attempt has been made to assess the primary production of the species in different agroecological regions ofIndia. Depending on length of growing period (LGP) and precipitation, country has been divided into six agroecological zones and available data on biomass produetion has been stratified into different agroecological zones. In general biomass varied from 11.9 t/ha in three year old plantation to 146 t/ha in 9 year old plantation in moist regions. In dry tropical region it varied from 5.65 t/ha in 5 year plantation to 135.5 t/ha in 9 year old plantation. In dry tropical regions biomass accumulation was more in cooler areas as compared to warmer areas. Where water is not the limiting factor comparatively higher mean annual temperature of around 25°C seems to produce higher biomass. A higher share of leaf biomass was observed in dry region. The root/shoot ratio was also higher in dry tropical region.

Earlier Sir H.G. Champion had compiled his monumental work 'Preliminary Survey of Forest Types of India and Burma' in 1936. The original work of 1936 was revised by Sir H.G. Champion with S.K. Seth which was published as 'A Revised Survey of the Forest Types of India'. Their work helped the forest managers and researchers all over the Indian sub-continent to prepare management plans for the scientific management of forests. India's forest types are very diverse in their compositions with a long evolutionary and geological history, occurring under many climatic and edaphic conditions. They have been undergoing subtle but significant changes in the composition of forests since the forest types were revised by Champion and Seth. These changes have taken place on account of climatic changes and anthropogenic causes (biotic pressure as well as management interventions). The present study was conducted by revisiting various forest types. It was aimed at assessing the changes that have occurred over a period of time since they were revised by Champion and Seth. The field survey covered more than 200 forest types and subtypes representing very diverse climatic and edaphic conditions across the country. The sample plots were generated randomly across different forest types. Data collected from the field surveys were analyzed for preparing the change matrix of forest types, basal area, importance value index, stem density and diversity indexes including similarity indexes. Impact of climate change on the vegetation was critically examined to see the species level responses to the changes in the rainfall and temperature regimes over the past years. The study has indicated many changes occurring at species and forest subtypes levels. The species level changes were observed largely in Shorea robusta (Sal), Tectona grandis (Teak) and Bamboo forests with regard to their distribution and species density. The study has indicated the absence of teak from very moist and moist teak sub-type and occurrence of many moist deciduous and semi-evergreen species. In central India, the low rainfall regime has shown the decline of Sal and occurrence of dry deciduous species. The study revealed that both positive and negative changes have been witnessed in various forest types. These findings could be used by the policy makers, scientists and foresters for evolving suitable strategies for futuristic management intervention so that the objectives of sustainable forest management are realised. The new classification of forest types has been proposed reflecting the present ecological, climatic, bio-geographic and edaphic influences on the vegetation composition and stand formation. In the proposed new classification, 10 major groups and 48 subgroups were identified.
