| 1 | Traditional farming in the mountainous region of Bangladesh and its modifications显示文摘Shifting cultivation is a traditional farming system practiced in the tropical mountainous areas. Although it has been widely perceived as an economically inefficient and environmentally harmful agricultural production system, recent science reviews, however, indicate that the deleterious impacts of shifting cultivation on environment may have been overestimated. Despite the pressures of agricultural intensification in areas where shifting cultivation occurs, farmers across the tropics still maintain this traditional farming system. The objective of this study was to explore existing traditional shifting cultivation practices and their various modifications including the innovative farming techniques developed by farmers in the Chittagong Hill Tracts(CHTs), the mountainous region of Bangladesh, and examine their importance with respect to recent socio-economic and environmental changes. The study revealed that shifting cultivation still exists as the most dominant farming method which supports livelihoods and culture of the hill ethnic people. However, demand for more food and household income to meet livelihood needs of an increasing population combined with a rapid deterioration of soil and water quality over decades contributed to development of innovative farming practices through fallow land farming, crop substitution, agroforestry and homestead gardening in the CHTs. Through these farming techniques farmers maintain a strong relationship with traditional knowledge system embedded in the ageold shifting cultivation practices. Today state policies and market forces act in favor of replacement of traditional farming with intensive cash crop agriculture. It seems that disappearance of traditional farming practices from the hills may threaten local biodiversity and food security. It may be recommended that shifting cultivation should be encouraged in areas where they have potential for contributing to preservation of native biodiversity and ecosystem services, and protection of local peoples' food security and cultural identity. | MISBAHUZZAMAN Khaled | 2016 | Journal of Mountain Science2016，13，8： | 1 |
| 2 | Effect of traditional management practices on woody species composition and structure in montane subtropical forests of Meghalaya,Northeast India显示文摘In Meghalaya, northeast India, the local people have the tradition of managing forest resources since early ages. The management practice varies and there are forests with high degree of protection, where no extraction(sacred forests) is allowed. There are also forests with moderate-level of protection and-extraction(reserved forests) as well as forests with low level of protection and open extraction(village forests). The present study was conducted to understand the impact of this traditional management system on the level of human disturbance, and on community composition and structure of the forests in Khasi hills of Meghalaya. The result revealed that disturbance index was low, whereas species richness, density and basal cover were significantly high in forests with high degree of protection(sacred forest) than those with low protection(reserved and village forest). Majority of endemic and threatened plant species were restricted to sacred forests as compared to the other forest types. Though these practices have ensured the sustainable use of forest resources by the local people but due to increased human-pressure and-disturbances, more effective conservation strategies need to be undertaken. Therefore, providing alternatives for fuelwood to local people, environmental education, encouraging afforestation and developmental activities involving local communities are recommended. | Aabid Hussain MIR Krishna UPADHAYA | 2017 | Journal of Mountain Science2017，14，8： | 0 |
