Drivers and mechanisms of forest change in the Himalayas
Global Environmental Change, 2021Abstract Mountains are critical ecosystems that have a strong influence far beyond their topographic boundaries. More than 50 million people inhabit the Himalayas, and more than one billion people depend on the ecosystem services they provide. Anthropogenic activities have driven concurrent deforestation and regeneration in the Himalayas, and ...

A group-strategyproof mechanism for Steiner forests.
2005In this paper we design an approximately budget-balanced and group-strategyproof cost-sharing mechanism for the Steiner forest game. An instance of this game consists of an undirected graph G = (V, E), non-negative costs ce for all edges e ∈ E, and a set R ⊆ V × V of k terminal pairs.

SAE Technical Paper Series, 1979
<div class="htmlview paragraph">The need for small, versatile, relatively low cost forest oriented timber harvesting equipment is a natural outgrowth of forest management as expressed through logging. Logging initially was dominated by horse energy, then by the adaptation of construction machinery to woods use, and now by woods equipment of ...

Journal of Forestry, 1947
Abstract Interest in improving output per man-day through introducing mechanized equipment is widespread. Not all devices that save labor produce savings in operating costs, particularly if they involve heavy fixed costs. The author discusses a few new developments and points out what they mean to the planner of forest operations.

Forests as Capital: Financial Mechanisms for Tropical Forest Conservation
Journal of Sustainable Forestry, 2015Tropical forest loss and degradation due to human activities have been persistent and intractable global problems. Model estimates suggest that current levels of finance for conservation and sustainable forest management (SFM) are insufficient and may need to increase by an order of magnitude in order to meet this challenge. This special issue presents

Forest Mechanization — A Challenge to the Industry
SAE technical paper series, 1967<div class="htmlview paragraph">An increasing demand for wood, accompanied by a decreasing supply of labor, is forcing the timber industry to mechanize. As industry strives towards the goal of complete mechanization, a number of challenges will be encountered.

Mechanisms of Deposition of Methylmercury and Mercury to Coniferous Forests
Water, Air, & Soil Pollution, 1995Deposition of methylmercury (MeHg) and mercury (Hg) to a coniferous forest have been investigated using field measurements. Samples of open field (OF) wet deposition, throughfall (TF) and litterfall (LF) have been collected and analyzed for MeHg and Hg during the period November 1991 to April 1994. Average concentrations in TF were 22.8 and 0.38 ng L-1,

Transfer Mechanisms Inducing a Sustainable Forest Exploitation
2005In this paper our concern is with deforestation as a global environmental issue. Foreign transfers from developed countries to forestry countries have been proposed for this goal. The problem is formulated as a Stackelberg differential game played over an infinite horizon, with the donor community as the leader and the aid recipient country as the ...

Mechanical site preparation for forest restoration
New Forests, 2012Forest restoration projects have become increasingly common around the world and planting trees is almost always a key component. Low seedling survival and growth may result in restoration failures and various mechanical site preparation techniques for treatment of soils and vegetation are important tools used to help counteract this.
