The population/biodiversity paradox. Agricultural efficiency to save wilderness.

چکیده
“I know of no time which is lost more thoroughly than that devoted to arguing on matters of fact with a disputant who has no facts but only very strong convictions” (Simon, 1996). The comment aptly summarizes a common experience (including my own) in dealing with technophobes. In one sense, the genetic manipulation (GM) debate can only be conducted on a level in which the participants are prepared to enlarge their knowledge and refine their views accordingly. I consequently have tried in this article to provide plenty of facts that can be used in discussion with reasonable participants. My recommendation is to forget those who are not prepared to modify in any way a prepared (i.e. ideological) position. My own view of GM is that its primary use to mankind must come initially in helping to solve fundamental problems that currently present themselves. These outstanding problems concern population, global warming, and biodiversity. In a longer version of this article I have tried also to provide some critique of current trends toward placing ecological views into agriculture in the hope of generating reasoned discussion. The full version of this article is on my web site (www.ed.ac.uk/;ebot40/ main.html). All the information below can be obtained from the referenced articles, although I have not always indicated where.

Assessing the Ecological Impacts of Agriculture Intensification Through Qualitative Reasoning
How to feed the world without loosing what is left of biodiversity? Two answers for this question are found in the literature. On the one hand, the “Land Sparing” paradigm suggests that increasing yield by means of intensive agricultural systems would fulfill the needs of human population and save natural landscapes. On the other hand, “Biodiversity Friendly Farming” argues that agricultural in...
متن کاملWilderness preservation and biodiversity conservation - keeping divergent goals distinct
C onservation biology, as developed and practiced in the United States, has the explicit aim of maintaining and encouraging biodiversity. The term “biodiversity” was introduced in 1986 by Walter Rosen as a shorthand for “biological diversity.” Although Rosen’s original intention was quite precise, biodiversity, according to a survey of US conservation biologists, has become a fashionable scient...
متن کاملAgricultural capacity and conservation in high biodiversity forest ecosystems.
Agricultural development is a leading cause of habitat destruction that increasingly threatens global biodiversity. To help understand the likelihood and implications of agricultural expansion in areas of high conservation importance, this article examines agricultural suitability in forested portions of biodiversity hotspots and tropical wilderness areas, regions with especially rich concentra...
متن کاملWilderness and biodiversity conservation.
Human pressure threatens many species and ecosystems, so conservation efforts necessarily prioritize saving them. However, conservation should clearly be proactive wherever possible. In this article, we assess the biodiversity conservation value, and specifically the irreplaceability in terms of species endemism, of those of the planet's ecosystems that remain intact. We find that 24 wilderness...
متن کاملThreats from urban expansion, agricultural transformation and forest loss on global conservation priority areas
Including threats in spatial conservation prioritization helps identify areas for conservation actions where biodiversity is at imminent risk of extinction. At the global level, an important limitation when identifying spatial priorities for conservation actions is the lack of information on the spatial distribution of threats. Here, we identify spatial conservation priorities under three promi...
