Human-Wildlife Conflicts in Paschim Kusaha Village of Koshi Tappu Wildlife Reserve,Sunsari District,Nepal

Human-wildlife conflict has been one of the most trouble-causing issues in many areas of Nepal including Eastern Nepal. This study assessed the human-wildlife conflict status in Paschim Kusaha Village of Koshi Tappu Wildlife Reserve (KTWR), Sunsari District, Nepal. Data were collected from 47 respondents of different households through questionnaire surveys and formal and informal interviews. Results revealed that the most destructive wild animals were wild elephants, wild boar, and wild water buffalo and the most raided crops were paddy (63.83 %), maize (19.15%), and potato (17.02%). Most of the encounters between humans and wildlife were recorded at night (after dusk and before dawn) (78.72%). Local people were suffering from damage of physical properties, human harassment or nuisance, and depredation of cropland due to wild animals. A total of 70% of respondents had a positive attitude towards conservation despite disturbing human mortality records (22 deaths in the last five years) from the reserve area and surrounding. Awareness of wildlife behavior together with conservation and easy access to compensation schemes were suggested to minimize conflicts in the area.     

Shifting dynamics of nature,society and agriculture in the Hindu Kush Himalayas: Perspectives for future mountain development

Current approaches for sustainable mountain development have several persisting warning signals. Economic globalization, profitoriented market development, and infrastructure development have significantly altered traditional nature-society interactions, increased environmental pressures, and challenged agricultural sustainability in the mountains. Some of the effects of globalization could also be beneficial. Social differentiation and disintegration of mountain communities' have weakened their collective stakes on natural resources resulting in decline in initiatives such as community forestry, collective water management, domestication of rapidly disappearing herbal species, and balancing of economic and ecological concerns. Population growth, food insecurity, unemployment, and increasing economic gaps between rich and poor have led to out-migration of youth. Sustained action promoting ownership of new initiatives for rehabilitating degraded mountain landscapes through macro-level global/national initiatives, mountain specific planning and development efforts is severely lacking in many areas on the Hindu Kush Himalayan region. Therefore, there is an urgent need for widening the scope of efforts directed to help mountain areas and communities, and a future thinking approach to enhance the sustainability of mountain areas as they are a valuable natural resource for humankind. This paper discusses the issues, opportunities, and provides suggestions for the future of mountain development.     

Detrital chromian spinels from beach placers of Andaman Islands,India: A perspective view of petrological characteristics and variations of the Andaman ophiolite

Along the east coast of the Andaman Islands, abundant detrital chromian spinels frequently occur in black sands at the confluence of streams meeting the Andaman Sea. The mineral chemistry of these detrital chromian spinels has been used in reconstructing the evolutionary history of the Andaman ophiolite. The chromian spinels show wide variation in compositional parameters such as Cr# [= Cr/(Cr + A1) atomic ratio] (0.13–0.91), Mg# [= Mg/(Mg + Fe²⁺) atomic ratio] (0.23–0.76), and TiO₂ (<0.05–3.9 wt%). The YFe³⁺[= 100Fe³⁺/(Cr + A1 + Fe³⁺) atomic ratio] is remarkably low (usually <10 except for south Andaman). The ranges of chemical composition of chromian spinels are different in each locality. The spinel compositions show very depleted signatures over the entire island, which suggests that all massifs in the Andaman ophiolite were affected under island‐arc conditions. Although the degree of depletion varies in different parts of the island, a directional change in composition of the detrital chromian spinels from south to north is evident. Towards the north the detrital chromian spinels point to less‐depleted source rocks in contrast to relatively more depleted towards the south. The possibilities to explain this directional change are critically discussed in the context of the evolution of Andaman ophiolite.
