A study was conducted to quantify runoff and soil loss under the cultivation of prominent medicinal and aromatic plants in the high hills of Nilgiris, in order to assess their relative soil and water conservation efficiencies. Six species, namely Geranium (Pelargonium graveolens), Rosemary (Rosmarinus officinalis) , Cineraria (Ceneraria maritima), Thyme (Thymus vulgaris), Mentha (Mentha piperita) and Digitalis (Digitalis purpurea) were planted in 15 m × 5 m plots on 15 percent land slope. Geranium recorded highest average green biomass yield followed by Digitalis, Cineraria, Mentha and Rosemary. Runoff and soil loss was maximum under Thyme followed by Cineraria because of their poor canopy cover. The lowest average annual soil loss and run off, over four years, was observed from Digitalis followed by Mentha and Geranium due to their quick establishment and higher canopy coverage. Relative Soil and Water Conservation Efficiency (RSWCE) varied from 36.4 per cent under Cineraria to 96.6 percent under Digitalis with Mentha, Geranium and Rosemary registering RSWCE of 95.1, 88.4 and 87.8 percent, respectively. It is suggested that Digitalis, Mentha, Geranium and Rosemary cultivation could be the best options for a diversified land use system as well as for cover crop, intercrop and vegetative barrier in the Nilgiris for effective soil conservation.- Management of Fringe Forests for Rural Livelihood and Forest Conservation

This paper reviews status, policies and programmes for fringe forest development in India and gives a vision statement for the development of fringe forests of the country, based on global and regional events which have changed the emphasis in the forestry sector in the way stakeholders perceive how forests should be managed in future and how dovetailing ongoing activities, programmes and resources of the line departments can develop rainfed social and ecological capital of the country in a holistic manner for a win-win situation for all concerned.Keywords

Assessing vulnerability to climate change and variability is an important first step in evolving appropriate adaptation strategies to changing climate. Such an analysis also helps in targeting adaptation investments, specific to more vulnerable regions. Adopting the definition of vulnerability given by IPCC, vulnerability was assessed for 572 rural districts of India. Thirty eight indicators reflecting sensitivity, adaptive capacity and exposure were chosen to construct the composite vulnerability index. Climate projections of the PRECIS model for A1B scenario for the period 2021-2050 were considered to capture the future climate. The data on these indicators were normalized based on the nature of relationship. They were then combined into three indices for sensitivity, exposure and adaptive capacity, which were then averaged with weights given by experts, to obtain the relative vulnerability index. Based on the index, all the districts were divided into five categories with equal number of districts. One more district was added to 'very high' and 'high' categories. The analysis showed that districts with higher levels of vulnerability are located in the western and peninsular India. It is also observed that the highly fertile Indo-Gangetic Plains are relatively more sensitive, but less vulnerable because of higher adaptive capacity and lower exposure.Keywords
