有机农业的基本标准及其产品的开发

在现代化农业面临的生态平衡失调、资源能源危机、环境污染和食物品质下降等一系列严重挑战面前,早在本世纪三、四十年代就有一些学者和实际工作者提出要发展有机农业来解决现代化农业带来的问题。所谓有机农业指的是一种在生产过程中不使用人工合成的化肥、农药、生长调节剂和家禽家畜饲料添加剂的农业。为了推动有机农业在世界范围内的发展,由来自英国、瑞典、南非、美国和法国等5个国家的5个单位的代表于1972年11月5日在法国发起成立了“国际有机农业运动联合会(International Federation of Organic Agr-iculture Movements,简称IFOAM)。其宗旨是联合世界上从事有机农业的单位和个人以建立一个在生态上、环境上和社会上是持续发展的农业。经过20多年的发展,这个组织已成为当今世界上最广泛、最庞大、最权威的一个拥有来自80多个国家500多个集体会员的国际有机农业组织。在该组织的推动下,世界上有机农业运动发展比较迅速,据欧洲共同体11个

Linnaeus’ study of Swedish swidden cultivation: Pioneering ethnographic work on the ‘economy of nature’

Carl Linnaeus’ work on the ‘economy of nature’ was a major early development in what became the modern field of ecology. This analysis suggests that a key subject of this work that has been ignored or misunderstood for 250 years is the rural livelihoods, especially swidden (or slash-and-burn) agriculture, which Linnaeus studied during his expeditions through rural Sweden. Rereading his reports in the light of modern work on swiddens, political ecology, and the history of science affords a new appreciation of Linnaeus’ insights into traditional systems of resource exploitation. The logic of nutrient cycling in swidden agriculture and its utilization of natural dynamics to serve human ends exemplify the principles of the ‘economy of nature’, and gave Linnaeus a philosophical basis for understanding and defending this system of agriculture as well as other rural resource use systems in Sweden. This analysis sheds new light on Linnaeus’ ethnographic work, his view of folk environmental knowledge, and his often derided identification with Sweden’s ethnic peoples.

Developments in greenhouse gas emissions and net energy use in Danish agriculture - how to achieve substantial CO(2) reductions?

Greenhouse gas (GHG) emissions from agriculture are a significant contributor to total Danish emissions. Consequently, much effort is currently given to the exploration of potential strategies to reduce agricultural emissions. This paper presents results from a study estimating agricultural GHG emissions in the form of methane, nitrous oxide and carbon dioxide (including carbon sources and sinks, and the impact of energy consumption/bioenergy production) from Danish agriculture in the years 1990–2010. An analysis of possible measures to reduce the GHG emissions indicated that a 50–70% reduction of agricultural emissions by 2050 relative to 1990 is achievable, including mitigation measures in relation to the handling of manure and fertilisers, optimization of animal feeding, cropping practices, and land use changes with more organic farming, afforestation and energy crops. In addition, the bioenergy production may be increased significantly without reducing the food production, whereby Danish agriculture could achieve a positive energy balance.     

Urban expansion and the loss of prime agricultural lands in Puerto Rico

In many countries where the economy has shifted from mainly agricultural to industrial, abandoned agricultural lands are lost to urbanization. For more than 4 centuries the Puerto Rican economy depended almost entirely on agriculture, but sociopolitical changes early in the 20th century resulted in a shift to industry. This shift in the economy, and an increase in population, has resulted in an increase in urban areas. This study describes the rate and distribution of urban growth on the island of Puerto Rico from 1977 to 1994 and the resulting influence on potential agricultural lands. Urban extent and growth were determined by interpreting aerial photographs and satellite imagery. The 1994 urban coverage was combined with a soil coverage based on agricultural potential to determine the distribution of urban areas relative to potential farmlands. Analyses showed that in 1977, 11.3% of Puerto Rico was classified as urban. After 17 years, urban areas had increased by 27.4% and urban growth on soils suitable for agriculture had increased by 41.6%. This represents a loss of 6% of potential agricultural lands. If this pattern of encroachment by urban growth into potential farmlands continues, Puerto Rico's potential for food production in the future could be greatly limited.
