By Arild Angelsen, David Kaimowitz

This publication has been built from a workshop on Technological swap in agriculture and tropical deforestation equipped through the heart for overseas Forestry examine and held in Costa Rica in March, 1999. It explores how intensification of agriculture impacts tropical deforestation utilizing case stories from assorted nation-states, utilizing various agricultural items and applied sciences and in differing demographic occasions and marketplace stipulations. counsel is additionally given on destiny agricultural learn and extension efforts.

Mathematical Modeling for System Analysis in Agricultural Research

This booklet presents a transparent photo of using utilized arithmetic as a device for bettering the accuracy of agricultural examine. for many years, information has been considered as the basic software of the clinical strategy. With new breakthroughs in pcs and software program, it has turn into possible and essential to increase the normal strategy in agricultural study via together with extra mathematical modeling methods.

Forest fragmentation in the southern Rocky Mountains

The forests of the southern Rocky Mountains of Colorado and Wyoming are a part of this region's usual historical past, offering invaluable ecological worth, crucial ordinary assets, a number of possibilities for out of doors sport, shelter for local organic variety, and solitude to americans who are looking to get away our crowded towns.

Biotechnology has come to a degree the place, by means of exchanging many of the age­ outdated practices of breeding, it will probably produce novel and stronger crops and animals which may larger serve people and their reasons. The suggestions of mobile and subcellular engineering, reminiscent of gene splicing and recombinant DNA, cloning, hybridomas and monoclonal anti­ our bodies, construction of human insulin, protein engineering, commercial fermentation, synthetic insemination, cryopreservation and ovum trans­ fer, plant tissue tradition and somatic hybridization, nitrogen fixation, phytomass construction for biofuels and so forth have complex drastically some time past decade, a result of availability of higher apparatus and the consolida­ tion of information.

Techniques in Wildlife Investigations. Design and Analysis of Capture Data

Thoughts for natural world Investigations emphasizes the layout of box experiences and the statistical inferences that may be made up of saw adjustments in animal abundance and populations. the data offered here's of price not just for flora and fauna administration but in addition for social and fiscal decision-making relating to the environmental results of human actions on flora and fauna populations.

The commodity booms discussed in this book by Wunder (Chapter 10) and Ruf (Chapter 16) provide good examples of such situations. 2. Endogenous prices The second main macroeconomic feedback mechanism operates via price changes. These include both output and input prices (including wages, although the previous section indirectly dealt with wage changes). If innovations substantially increase the supply of agricultural output (and possibly greatly increase the demand for labour), output prices may go down while wages and other input prices may rise.

Particularly damaging floods occurred in the 1830s and again in the 1850s, and the Swiss Forestry Society helped convince authorities that forest problems were partially responsible for the floods. In response to a petition from the society’s president, Elias Landolt, in 1856, the federal government commissioned a major survey of forest condition under Landolt’s supervision. The report concluded that forests were being depleted and that deforestation had made river discharge more irregular and increased the risk of avalanches and falling rocks (Landolt, 1862).

4 Some people use the term 'land-intensive' interchangeably with 'land-saving' or 'yield-increasing'. It is, however, by no means self-evident whether land-intensive means that farmers use a lot of land per unit of labour and capital (also referred to in the literature as extensive land use) or the opposite. 5 One could argue that agricultural intensification should be defined in terms of output per unit of the scarce factor. Since labour is often the scarce factor at the forest frontier, a third option would be to divide through by labour in equation (1), and focus on labour productivity (output per worker) and the land and capital requirements per worker.
