Die Differenzierunggas-, rauch- und staubförmiger Immissionen bei landwirtschaftlichen,gartenbaulichen und forstwirtschaftlichen Kulturen

Summary The differentiation between acute, direct chronic and indirect chronic immissions caused by atmospheric pollution brought about by emissions having the nature of gas, smoke and dust is described. Several positive examples are quoted to the question whether indirect chronic immissions are possible without damage to growth up, yield and/or production.A differentiation has value for autotrophic and heterotrophic life forms:1. Insignificant immissions in the animate world prevail when autotrophic/heterotrophic life forms are not adversely affected, as compared with their condition in their usual situation and surroundings, i. e. when: their anatomical/morphological development, their function, their efficiency, their powers of propagation, their immunity to disease, their longevity and their physiological function and/or psychical well-being are not impaired.2. Considerable immissions in the animate world prevail when the development, function, efficiency, powers of propagation, immunity to disease and/or general well-being of autotrophic/ heterotrophic life forms, as compared with their condition in their usual situation and surroundings, are affected by reversible physiological/ psychical disturbances (direct and indirect chronic immissions) but when their longevity remains unaffected and when anatomical/morphological anomalies, changes and/or damage (acute immissions) do not occur.3. Severe immissions in the animate world prevail when the development, function, efficiency, power of propagation, immunity to disease, longevity and/or general well-being of autotrophic/heterotrophic life forms, as compared with their condition in their usual situation and surroundings, is affected or interrupted by repeated or irreversible physiological/psychical disturbances (direct and indirect chronic immissions), whereby, under certain circumstances, limited but typical anatomical/ morphological anomalies, changes and/or damage (acute immissions) occur to separate organic parts.4. Excessive immissions in the animate world prevail when the development, function, efficiency, power of propagation, immunity to disease, longevity and/or general well-being of autotrophic/ heterotrophic life forms, as compared with their condition in their usual situation and surroundings, are prevented or ended by repeated or irreversible physiological changes or by psychical disturbances (direct and indirect chronic immisssions), whereby, under certain circumstances, some organs or complete organisms suffer extended and typical anatomical/morphological anomalies, changes and/or damage (acute immissions).

世界约30个国家、地区的森林资源是增长的

把世界约30个森林资源增长的国家、地区分成4类:1.依靠雄厚的森林资源,虽经营粗放,近40年来,资源还是增长了,如苏、美、加;2.荒地造林扩大了森林资源、如新西兰、南非、斯威士兰、英国;3.通过集约经营现有林,欧洲大多数国家、日本的森林蓄积量明显增长;4.以外养内,巧妙利用外国资源,既满足了本地区木材需要,保护了自己的资源,又谋得了进口木材所需的外汇。中国应走哪条路?

Capacity for Timber Management in Small and Medium Forest Enterprises: A Case Study from the Peruvian Amazon

With the implementation of a new legal framework for more responsible forest management in Peru, private small-medium forest enterprises (SMFEs) have become the most important social actors engaged in commercial forestry in the Peruvian Amazon. Despite the role of SMFEs in contributing to employment and local economic growth, there is little information with respect to their economic performance and capacities. This is a hindrance to efforts aimed at better characterizing this important sector and its influence on the development and conservation of tropical forests. For this study, 29 private SMFEs were surveyed to inventory their capital assets in order to evaluate their capacities to carry out timber management. Results indicate that SMFEs vary greatly in terms of their produced and natural capital assets, and consequently in their forest management capabilities as well. While most SMFEs lack adequate capacity for sustainable forest management, those that had more valuable timber resources and physical infrastructure attained forest certification. SMFE capacities depend greatly on external mechanisms to ensure consistent technical and financial assistance.     

The implications and challenges of First Nations forestry negotiations in British Columbia,Canada: The Tl’azt’en Nation experience

Abstract

This article examines the implications and limitations of First Nations forestry negotiations in British Columbia (BC), Canada by assessing how effectively the Tl’azt’en Nation is able to realize benefits under the current form of negotiations. The primary goal of the Tl’azt’en Nation has always been to defend their Aboriginal interests within their ancestral lands, which would entail the cessation of clear-cutting on their traditional territory. Although the community has pursued some economic opportunities in the forestry sector to improve their socioeconomic conditions, despite their efforts, the socioeconomic status of the community remains unchanged. The collective experience of the Tl’azt’en Nation illustrates that simply obtaining certain forest tenures and short-term-based revenue sharing agreements does not adequately meet their forestry and self-sufficiency goals. Without addressing the fundamental issues and challenges facing the community, the current practice of forestry negotiations between the Provincial government and the Tl’azt’en Nation has produced no significant benefits to the community.     

Woody leguminous trees: New uses for sustainable development of drylands

Woody leguminous species are valuable crops because of their nutritional, economic, and ecological characteristics. Such crops have aided in the recovery of marginal lands for agricultural development due to their ability to fix nitrogen, control erosion, and act as a refuge for other species, in addition to their capacity to improve soil mineral composition and microbial biodiversity. Nevertheless, some leguminous trees are recognized to be one of the worst invasive species that affect negatively biodiversity and the entire ecosystem balance. In this study, we review new global uses for some woody leguminous crops, highlighting new nutraceutical and pharmacological properties, their uses as bioenergy sources, and their ecological uses for bioremediation opening new possibilities of management. We aim to bring knowledge on the multiple benefits that these woody plants continue to provide to humans from economic, social, and environmental standpoints.
