The lofty and snow-clad mountain peaks, alpine pastures, picturesque landscapes of mid-altitudes, perennial rivers, dense coniferous forests and the river valleys make the Himalaya distinct from the other parts of the world. Its world famous highland sacred places – pilgrimages and various tourists’ destinations have further enhanced its significance. Being as an underdeveloped and remote region for the centuries; the Himalaya is largely unexplored and is very little known. Similarly, geographical writings on the Himalaya are unobtainable. Yes, of course, it gives me an immense pleasure to review the Geography of Himalaya whereas; it seems very incomprehensible because of the limited access to literature. In this article, the physical and cultural aspects of the Himalayan geography are illustrated in detailed. The term ‘Himalaya’ is derived from the Sanskrit word which denotes the abode of snow. The Hindus believe it as the symbol of divinity, an abode of the Lord Shiva. Being as a source of the pious river Ganga and a land of the world famous highlands and valleys pilgrimages to Hindus, the Himalaya has tremendous cultural significance. It has also natural, economic and geo-strategic importance. It is inevitable to present here the major characteristics of the Himalaya. Its panoramic landscape makes it as the world famous tourism destination. Nonetheless, it protects India, in security point of view, from its two neighbouring states viz. Pakistan from the northwest and China from the north and northeast; regulate the climatic conditions of the Ganges Valley and the Central India and supports livelihoods for over 50 percent of the total population of India. The Himalaya also protects the mainland of India from the severe cold waves that origin from the Tibetan plateau. Scholars from worldwide have conducted studies on the various aspects of the Himalaya such as orogeny, geography, geology, land, people, occupations, farming 183 systems, culture, tourism and human races. Most of the studies were carried out on the bases of its horizontal and vertical dimensions. As the Himalaya is divided into four horizontal divisions viz. the Western Himalaya, comprises of Jammu and Kashmir Himalaya, Himachal and Uttarakhand Himalayas; the Central Himalaya includes Nepal Himalaya; the Eastern Himalaya, consists of Sikkim and Arunachal Himalayas and the eastern extension of the Himalaya comprises of Nagaland, Manipur, Mizoram, Tripura, Meghalaya and the hills of West Bengal and Assam; the scholars of different disciplines working in the Himalaya have conducted studies on particular aspect or on particular region. The whole Himalayan region from west to east has numerous universities and educational institutions and some substantial research have been produced by the scholars working in these universities and in the higher learning centres. The main purpose of this study is to review the work, carried out on the Himalaya, particularly on biogeography and biodiversity, climate change, environment, food security, agriculture, socio-economic and cultural development during 2012-2016. Development of Geographical Studies in the Himalaya: A Review In this paper, literature is reviewed on the various aspects of the Himalayan Geography and the review period is from 2012 to 2016. Biogeography and Biodiversity The Himalaya is the home of many cultivars/races and a hotspot of global biodiversity. It is a repository of faunal and floral resources. Distribution pattern of these floral and faunal species is determined by the climatic conditions, as the whole Himalaya obtains subtropical to temperate, cold, alpine and frigid cold climates. Lots of work has been carried out by the academicians and scientists on ecology, ecosystems and biodiversity of the Himalayan region. Further, a study on distribution on flora and fauna and climate change impacts on them has also been carried out by these scientists. Meanwhile, the role of geographers in studies of biogeography in the Himalayan region is limited. During the recent years, a limited work on Himalayan biogeography was conducted by forests scientists. Tree line dynamics in northwestern Indian Himalaya (Negi, 2012), timberline ecotone in the Himalayan region (Peili et al., 2012), changes in floral species (Singh et al., 2014), managing ecosystem services for enhancing climate change adaptation (Nakul, 2014), ethno-medicinal plants and use pattern in the Garo hills (Singh et al., 2014), geographical extension of Lycophyta and Fern in the Eastern Himalaya (Singh et al., 2014), monitoring ecosystem boundaries in the Himalaya (Rawat, 2012), glimpses of forestry research in the Indian Himalayan Region (Negi and Dhyani, 2012), soil-vegetation ecosystems (Sharma, 2013) and valuation of forest ecosystem services (Negi, 2013) are amongst the major significant works carried out on the Himalaya. Forest diversity, use pattern and management (Sati, 2014) and altitudinal zonation of floral biodiversity and conservation pattern in the eastern extension of the Himalaya (Sati, 2015) are the other major contributions to biogeography of the Himalayan region. 184 Environment and Climate Change Issues Environmental Geography of the Himalaya is burning, very comprehensive and a centre of discourses amongst the all stakeholders, mainly environmentalists worldwide. The whole Himalayan region is ecologically fragile, geologically sensitive and seismically and tectonically active (Sati, 2014). The global changes on the landscape and on the atmosphere of the Himalaya can be noticed everywhere. The Himalaya is more sensitive to environmental pollutions – water, air, soil and noise. Tourism activity and increase in infrastructural facilities have accentuated environmental degradation. High growth in population, shrinking agricultural land, depletion of biodiversity resources and increasing number of vehicles has altogether enhanced environmental degradation. These drivers have also influenced the climate regime as climate change has become the major issue and phenomenon in the Himalaya. The whole Himalaya is so sensitive and highly vulnerable to climate change (Singh and Mal, 2014). Further, climate change implications on the whole landscape in general and fauna, flora and on the Himalayan glaciers in particular has become an emerging concern particularly after IPCC (2007) report which says the climate change impact on the Himalayan glaciers is higher than the other parts of the world. It further says that the Himalayan glaciers are melting so rapidly (Thakur and Singh, 2014). In the Himalayan region, many governmental and non-governmental organizations are dealing with the issues of changing environment. Surface ozone concentration and its behavior with aerosols in the northwestern Himalaya (Sharma et al., 2013), black carbon concentration and its apportionment in particular matter in Mohal Kullu (Sharma et al., 2013), distribution of source particulate matter in Kullu valley (Sharma et al., 2013), ambient air pollution and its sources in the semi-rural sites in the northwestern Himalaya (Chand et al., 2013), reviving dying springs: climate change adaptation experiments from the Sikkim Himalaya (Sandeep et al., 2012), hydro-geological studies and action research for recharge and development of hill top lake restoration in Sikkim (Mahamuni and Kulkarni, 2011), local perception of climate change in the Himalaya (Chaudhary and Bawa, 2011). Consistency of local perceptions of climate change in the Kangchenjunga Himalaya landscape (Chaudhary et al., 2011), climate change accelerating hydrological hazards and risks in Himalaya (Rawat et al., 2011), rapid cost effective and high resolution assessment of climate related vulnerability of rural communities in Sikkim Himalaya (Tambe et al., 2011), global warming, glacial lakes and cloudburst in Garhwal-Kumaon Himalaya (Pranab, 2015), Himalayan tsunami: cloudburst, flash flood and death toll (Pranab, 2013), impact of climate change on Himalayan glaciers and glacial lakes (Bajracharya, 2014) and black carbon measurements during winters in an environmental observatory at Mohal-Kullu in the northwestern Indian Himalaya (2103) are amongst the major contributions in the field of environment and climate change during the recent period. The present author also published substantial research on climate change impact on agriculture (2015), socio-economy (2015) and food security (2015). 185 Food Security, Agriculture and Development Food security, agriculture and development are the major issues of discussion in the whole Himalayan region. The reason of this is that agriculture is the main base of income and economy. Meanwhile, mode of practicing agriculture is traditional and output from it is less (Anand, Chandan and Singh, 2012; Mahoa, Singh and Heitala, 2012). Although, the natural resources availability is abundant in the Himalayan region yet, these resources are widely unused (Singh and Heitala, 2014). Thus, the Himalaya is called ‘a rich land of the poor people’ (Sati and Kumar, 2004).
