This paper argues that the incipient tensions over the Brahmaputra between India and China has become a considerable threat and cause for concern to the downstream dwellers of India's North East Region (NER), especially Assam and Arunachal Pradesh. It enlarges the term 'Brahma-hypothesis' and considers Chinese 'hydro-hegemony' over the Brahmaputra as a 'national security' threat to India. It also argues that apart from having the occasional Memorandum of Understanding (MoU) with China, India should seek to develop with China and other countries a multilateral diplomatic agreement regarding the management of the Brahmaputra River to secure India's vital interests at national and regional levels. This is also necessary to minimise the sense of insecurity continuously growing in the minds of the people of the NER. [ABSTRACT FROM AUTHOR]

The Ganges, Brahmaputra, and Meghna (GBM) river system flows through five countries – Bangladesh, Bhutan, China, India, and Nepal – characterized by large population, limited land resources, and frequent floods and natural hazards. Although the GBM region is well endowed with water sources, this is one of the poorest regions in the world. Its economy and human and environmental health depend on water, and water is thus at the heart of sustainable development, economic growth, and poverty reduction. This paper examines the opportunities for, and potential socio-economic benefits of, water resource management in the GBM region in the face of changing climate. It argues that water can be an entry point for addressing challenges common to the region, particularly through multi-purpose river projects that store monsoon water, mitigate the effects of floods and droughts, augment dry season river flows, expand irrigation and navigation facilities, generate hydropower, and enhance energy and environmental security. The paper emphasizes the importance of effective regional cooperation in water management to achieve these benefits. Upstream–downstream interdependencies necessitate development of a shared river system in an integrated and collaborative manner. [ABSTRACT FROM PUBLISHER]

Abstract: Aeolian sandy land in the Yarlung Zangbo River basin has attracted the attention of many researchers. However, its dynamics as well as its relevance to various factors has rarely been reported with integrated studies. In this paper, spatio-temporal dynamics of the aeolian sandy land in the basin was studied by interpreting Landsat images acquired from 1975, 1990, 2000, and 2008 with the help of geographic information system (GIS) technology. Spatially, the results showed a decreasing trend from west to east, which is from the Maquanhe wide valley in the headwater area to the middle and lower reaches of the river basin. Temporally, aeolian sandy lands in the basin showed a slow increasing trend, with an increase of 10.5% during the 1975–2008 period, spreading most quickly during the period of 1990–1999. The factors related to dynamics of aeolian sandy land were analyzed from the perspectives of two driving factors, climate changes and human activities. The climate-dominated natural factors are the internal driving forces for the development of aeolian sandy lands, and the human factors are the external driving forces responsible for the increase of the aeolian sandy land area.
