| 1 | Paradigm and Ecological Implication of Changing Agricultural Land-use:A Case Study from Govind Wildlife Sanctuary,Central Himalaya,India显示文摘The paper scrutinizes that the changes in any sub-system(i.e.agriculture,livestock and forest) have direct impact on biophysical and social processes in village ecosystem of the central Himalayan region.In view of this,we studied the changes in spatial patterns of agricultural land use and dependency of agroecosystem on forest and animal husbandry over a period of two decades.Based on data analysis it was found that the cultivation of some traditional crops has either been abandoned in the area or declined by 25%-85% due to introduction of cash crops viz.,potato,kidney bean and apple farming with acreage increased up to 51%-72% in the last three decades.Livestock population of different categories has declined drastically by 17%-75%,and has resulted shortage of farmyard manure,deterioration of soil quality and fertility which leads to un-sustainability of agriculture system.The changes in agrobiodiversity have led to the dramatic increase in soil loss and runoff from the croplands together with the increase pressure on forests.The economic evaluation of each crop showed higher monetary benefit from cash crops as compared to traditional crops.Among all the evaluated crops,the monetary output/input ratio was found highest(3.04) for kidney bean and lowest(1.26) for paddy.Changes in land use and management have improved household income but at the cost of forest degradation,less productive animal husbandry and loss of agrodiversity in the region.Therefore,there is an urgent need to bring desirable changes in agricultural policy,research,land use and efficient management of the resources for maintaining sustainability in agro and Himalayan forest ecosystem. | Vikram S.NEGI Rakesh K.MAIKHURI Lakhpat S.RAWAT | 2012 | Journal of Mountain Science2012，9，4： | 3 |

| 4 | Climate change impact in the Western Himalaya:people's perception and adaptive strategies显示文摘The Himalaya represents a vast mountain system and globally valued for its significant role in regulation of global as well as regional climate that has direct impact on biodiversity and ecosystem services crucial for sustenance of millions of people in Himalaya and adjoining areas. However, mountain regions worldwide are impacted by climate change and at the same time represent distinctive area for the assessment of climate related impacts. Climate change impacts in Himalayan region have its implications on food production, natural ecosystems,retreat of glacier, water supply, human and animal health and overall human well being. The livelihood and food security of the people inhabited in region largely depend on climate sensitive sectors i.e.agriculture, livestock, forestry and their interlinkages with each other, and has the potential to break down food and nutritional security as well as livelihood support systems. People's perception and understanding of climate can be an important asset when it comes to adaptation to climate change impact;however it is not taken into consideration for the development of policy design and implementation of modern mitigation and adaptation strategies by governments and other civil society organizations.The knowledge of local people and farming communities for rural landscape management and sustainable use of bioresources is gaining credence as a key strategy to cope up with the climate change.Therefore, the present study analyzes the indigenous knowledge of local people and their perceptions on climate change, and also documented adaptation approaches at local level in mountain ecosystem of western Himalaya. The study could be useful to policy makers to design appropriate adaptation strategies to cope up with the impacts of climate change. | Vikram S.Negi Rakesh K.Maikhuri Dalbeer Pharswan Shinny Thakur Pitamber P.Dhyani | 2017 | Journal of Mountain Science2017，14，2： | 1 |
| 5 | 印度北方河流中主要鲤科鱼类卡拉鲃的年龄和生长(英文)显示文摘为了获得印度北部赣达(Ganga)盆地河流中野生卡特拉鲃种群的年龄结构和重要生长参数,对该鱼的年龄和生长进行了研究。鳞片取自商业捕捞和实验室饲养的样品。根据研究分析,该鱼最大年龄可达8龄;巴吉拉蒂河(Bhagirathi R.)的种群平均体长为521·51 mm,退算体长为288·9 -1132·3 mm;旁遮普邦(Punjab)Satluj河种群平均体长为641·6 mm,退算体长为335·4 -1096·08 mm。2龄时,种群线性生长率(Cl)和体重增加率(Cw)表现出迅速下降的趋势。其它生长参数值(Clt)也呈现快速下降。退算体长差异(ANOVA)分析显示,生活在赣达盆地不同流域中的种群, 1+-4+龄组的长度差异较明显(P<0·05) ,高龄组(5+-8+)差异不显著。根据本项研究结果,提出了对印度北部赣达盆地相关河流中生活的野生卡特拉鲃种群资源持续利用的对策。 | Prashant K.DEEPAK Uttam K.SARKAR Raje S.NEGI Samir K PAUL | 2008 | 动物学报2008，54，1： | 0 |
| 6 | The Potential Contribution of Wildlife Sanctuary to Forest Conservation: A Case Study from Binsar Wildlife Sanctuary显示文摘Forest vegetation of a protected area(Binsar Wildlife Sanctuary) in Kumaun region(west Himalaya) was analysed for structure,composition and representativeness across three different altitudinal belts,lower(1,600-1,800 m a.s.l.),middle(1,900-2,100 m a.s.l.) and upper(2,200-2,400 m a.s.l.) during 2009-2011 using standard phytosociological methods.Four aspects(east,west,north and south) in each altitudinal belt were chosen for sampling to depict maximum representation of vegetation in the sanctuary.Population structure and regeneration behaviour was analysed seasonally for two years to show the establishment and growth of tree species.A total of 147 plant species were recorded from the entire region of which 27 tree species were selected for detailed study.Highest number was recorded at upper(18 species),and lowest at lower altitudinal belt(15 species).The relative proportion of species richness showed higher contribution of tree layer at each altitudinal belt.The population structure,based on the number of individuals,revealed a greater proportion of seedling layer at each altitudinal belt.The relative proportion of seedlings increases significantly along altitudinal belts(p<0.05) while opposite trends were observed in sapling and tree layers.The density of sapling and seedling species varied non-significantly across seasons(p>0.05).The density values decreased in summer and increased during rainy season.As far as the regeneration status is concerned,middle and upper altitudinal belts showed maximum number of species with fair regeneration as compared to lower altitudinal belt.Overall density diameter distribution of tree species showed highest species density and richness in the smallest girth class and decreased in the succeeding girth classes.This study suggests that patterns of regeneration behaviour would determine future structural and compositional changes in the forest communities.It is suggested that the compositional changes vis-à-vis role of ‘New' and ‘Not regenerating' species need priority attention while initiating conservation activities in the sanctuary.This study calls for exploring other less explored Wildlife Sanctuaries in the Himalaya and across the world,to achieve overall biodiversity status in these protected areas and thus to justify their role in conserving biodiversity in the region. | Balwant RAWAT Vikram S.NEGI Janhvi MISHRA RAWAT Lalit M.TEWARI Laxmi RAWAT | 2013 | Journal of Mountain Science2013，10，5： | 0 |
