韩国是如何在海上扩大国土的?

打开韩国的卫星图,会发现看上去不大的韩国大部分国土皆为山地丘陵,适合大规模农业生产的平原地形稀少。可能正是因为这样不利的自然条件,这个国家的人口高度集中于几个大城市,尤其首都首尔。     

Land Use Changes in Himalaya and Their Impacts on Environment, Society and Economy： A Study of the Lake Region in Kumaon Himalaya India

The traditional resource use structure in Himalaya has transformed considerably during the recent past, mainly owing to the growth of population and the resultant increased demand of natural resources in the region. This transformation in resource use practices is particularly significant in the densely populated tracts of Himalaya. As a result, cultivated land, forests, pastures and rangelands have been deteriorated and depleted steadily and significantly leading to their conversion into degraded and non-productive lands. These rapid land use changes have not only disrupted the fragile ecological equilibrium in the mountains through indiscriminate deforestation, degradation of land resources and disruption of the hydrological cycle, but also have significant and irreversible adverse impacts on the rural economy, society, livelihood and life quality of mountain communities. It has been observed that the agricultural production has declined, water sources are drying up fast due to decreased ground water recharge and a large number of villages are facing enormous deficit of critical resources, such as food, fodder, firewood and water, mainly due to unabated deforestation. As a result, the rural people, particularly the women, have to travel considerably long distances to collect fodder and firewood and to fetching water. It is therefore highly imperative to evolve a comprehensive and integrated land use framework for the conservation of the biophysical environment and sustainable development of natural resources in Himalaya. The land use policy would help local communities in making use of their natural resources scientifically and judiciously, and thus help in the conservation of the biophysical environment and in the increasing of the productivity of natural resources. The study indicates that conservation of forests and other critical natural resources through community participation, generation of alternative means of livelihood, and employment in rural areas can help increase rural income as well as restore ec

富庶到贫穷的千年转变

<正>孟加拉是世界上50个最不发达国家之一,人民生活十分贫困,经济基础薄弱,资源贫乏,生产力水平落后,人口整体素质低下;经济以农业为主,约80%的人口生活在农村,农业产值占国民产值55%。孟加拉国也是海上丝绸之路上重要的沿途国之一,与中国有着悠久的贸易、文化交往历史。历史证明,海上丝绸之路不仅促进了中国各民族的融合,还贯穿东西,加强了中国、印度次大陆、波斯、欧洲和阿拉伯地区之间的政治、经济和文化交流。作为与中国的参照对象,印度是很值得研究的对象。而印度古代史的
