Climate Change And Subsistence Farming - 2247 Words

2.2 Climate Change and Subsistence Farming Climate change has the potential to transform food production, especially the patterns and productivity of crops, livestock, and fishery systems; and to reconfigure food distribution, markets, and access (Nelson et al., 2009). Chen et al. (2012) observed that climate change has already had a negative impact on Asia through extreme temperatures, frequent flooding and droughts, sea level rise, and increased salinity of water supplies for rainfed agricultural areas. Most Asian countries are quite dependent on their domestic supplies of rice. The International Rice Commission (2003) indicates that Bangladesh, China, India, Indonesia, and Vietnam are the major producers of rice, producing more than 70% of the world’s volume. The Asian rice-producing countries tend to consume most of their domestic rice production. Nevertheless, Thailand and Vietnam are able to export some rice to neighboring countries such as Bangladesh, Indonesia, and the Philippines. Dasgupta et al. (2009) identi fied ten developing countries whose land areas are most exposed to the potential threat of a one-meter rise in sea level. Among the countries most affected by sea level rise are Bangladesh, China, Taiwan, and Vietnam and these are all rice-growing and rice-consuming countries. Using a partial equilibrium global rice trade model, Chen et al. (2012) investigated the potential impact of sea level rise combined with climate-induced crop yield change on global riceShow MoreRelatedDeforestation And Its Effects On Society1308 Words   |  6 Pagespopular belief, however, deforestation can also provide as a benefit. It allows people internationally to have access to a common resource, lumber, and creates room for employment; in some areas, deforestation could actually positively affect climate change. It is critical to weigh both pros and cons of deforestation as well as its effects on society, environmentally and economically. Deforestation’s negative outweigh the positives; how ever, the positives are crucial to function our society globallyRead MoreSubsistence Agriculture And Economic Development915 Words   |  4 Pages1) Mellor, J.

These climate conditions such as extreme heat, wetlands, and thick woods greatly obstructed the development of the tribal civilization. Tribal civilization relied on fishing, collecting, and hunting. Tribal bands were typically nomadic, moving around the various terrains in a given area. Their movements were often repetitious, and would mostly occur because of food migrations or seasonal plant changes.
