Forest management and biotechnology: the case of a selective-logging regime
One of the most important instruments to support the sustainable development of forests, and reinforce the multiple services that they provide is the selective-logging regime. This paper aims to quantify the potential benefits of biotechnology under this type of regime. With this purpose, an empirical analysis is conducted to determine the optimal selective-logging management for a stand of Pinus ...

Old growth logging: does it matter if environmental protection costs jobs?
This paper examines the assertion that "environmental protection costs jobs", a point that is thematic in the Australian state of Tasmania where banning clear felling of old-growth forests is vigorously resisted because of associated job losses. The debate between "jobs" and "environment" protagonists often originates in disagreements about political power, economic growth, distributional ...

Population growth and forest sustainability in Africa
Recent distressing trends in climate change, population explosion and deforestation have inspired this paper, which completes the existing literature by providing empirical justification to hypothetical initiatives on the impact of population growth on forest sustainability in Africa. Using three instruments of forest exploitation, the study shows how rural, agricultural and national population ...

The influence of forest harvesting on landscape spatial patterns and old-growth-forest fragmentation in southeast British Columbia
Habitat fragmentation is considered one of the major conservation issues of recent decades. We tested predictions of landscape patterns in a 352,253-ha managed forest area in southeast British Columbia. We did this by focussing on forest fragmentation concerns among old-growth, harvest, and wildfire patches in 44 delineated landscapes using patch indices as measures of landscape pattern. We found ...

Variability in Leaf Area and Stemwood Increment Along a 300-year Lodgepole Pine Chronosequence
Large disturbances such as the 1988 Yellowstone fires produce considerable spatial heterogeneity in ecosystem processes across landscapes, in part by affecting vegetation structure. However, the persistence of this heterogeneity with time since disturbance, and thus the role of large disturbances in shaping the heterogeneity of ecosystem processes over large spatial and temporal scales, remains ...

A Model for Communal Forest Management
Guna Yala, an autonomous indigenous territory inside Panama, is one of the most unusual places on the planet, where the Guna people have preserved their way of life and the forest around them thanks in large part to their exceptional land rights and sovereignty. At first glance, life on Guna Yala’s dozens of inhabited Caribbean islands seems idyllic — a place without cars, with little ...

9 Maps that explain the World`s Forests
This post is co-authored with Dave Thau, senior developer advocate for Google Earth Engine, Google's satellite image processing platform. By the time we find out about deforestation, it’s usually too late to take action. Scientists have been studying forests for centuries, chronicling the vital importance of these ecosystems for human society. But most of us still lack timely and reliable ...

Model forecasts long-term impacts of forest land-use decisions
The drive to develop crops for use as biofuel, continues to raise questions about additional uses of forest land. A cutting edge computer model developed at North Carolina State University offers detailed insight to predict the environmental impact – along with understanding forest ecosystem response to global climate change. “We think the model will help policy makers and forest ...

Economic implications of different cork oak forest management systems
The agro-silvopastoral system 'montado' is mostly dominated by Mediterranean evergreen oaks such as, cork oak (Quercus suber L.) and holm oak (Quercus rotundifolia). The 'montado' production system management aims the maintenance of a balanced sustainable land use to cope with the Mediterranean climate variability. One important issue in cork oak forests is the control shrub growth in order to ...

Shrinking forests: The many costs
In early December 2004, Philippine President Gloria Macapagal Arroyo 'ordered the military and police to crack down on illegal logging, after flash floods and landslides, triggered by rampant deforestation, killed nearly 340 people,' according to news reports. Fifteen years earlier, in 1989, the government of Thailand announced a nationwide ban on tree cutting following severe flooding and the ...

Protecting and restoring forests
Protecting the earth’s nearly 4 billion hectares of remaining forests and replanting those already lost are both essential for restoring the earth’s health, an important foundation for the new economy. Reducing rainfall runoff and the associated flooding and soil erosion, recycling rainfall inland, and restoring aquifer recharge depend on simultaneously reducing pressure on forests and on ...

Book Byte: We Can Reforest the Earth
Protecting the 10 billion acres of remaining forests on earth and replanting many of those already lost are both essential for restoring the earth’s health. Since 2000, the earth’s forest cover has shrunk by 13 million acres each year, with annual losses of 32 million acres far exceeding the regrowth of 19 million acres. Restoring the earth’s tree and grass cover protects soil ...

Planting trees and managing soils to sequester carbon
As of 2007, the shrinking forests in the tropical regions were releasing 2.2 billion tons of carbon per year. Meanwhile, expanding forests in the temperate regions were absorbing 0.7 billion tons of carbon annually. On balance, a net of some 1.5 billion tons of carbon were being released into the atmosphere each year, contributing to global warming. The tropical deforestation in Asia is driven ...

Forest & Plant Canopy Analysis - Tools & Methods
Canopy Analysis for Crop, Forest & Plant Research The range of applications of canopy cover analysis is truly astounding. Canopy analysis derives its usefulness from the vitality of the canopy. Many methods to measure canopy cover have been developed in the last 80 years to meet various objectives. Not surprisingly, there have been several comparisons of the tools in different parts of the ...

“Swapping Land” to Produce Sustainable Palm Oil in Indonesia
Indonesia has the world’s third-largest rainforest, which is a haven for biodiversity and an economic lifeline for many rural communities. However, Indonesian forests are in rapid decline and the country regularly tops deforestation hotspots lists. The key to protecting Indonesia’s forests remains reforming its massive forestry and agriculture sectors. By giving these industries the ...
