Drivers and mechanisms of forest change in the Himalayas

Global Environmental Change, 2021
Abstract 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 ...

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.

A group-strategyproof mechanism for Steiner forests.

2005
In 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.

Forest Oriented Mechanization

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 ...

Mechanizing Forest Operations

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, 2015
Tropical 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

Mechanisms of Deposition of Methylmercury and Mercury to Coniferous Forests

Water, Air, & Soil Pollution, 1995
Deposition 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,
