On optimal forest management: a dynamic programming approach
This paper studies optimal any-aged forest management, including uneven-aged and even-aged management as special cases. The approach is based on applying a dynamic programming approach. Dynamic optimisation is applied to study optimal profit-maximising harvesting policies, based on decomposing the forest management problem to smaller subproblems. The optimal harvesting policy implies a ...

Impacts of harvest residue management on soil Carbon stocks in a plantation forest
The impacts of plantation forest management on soil C stocks in New Zealand need to be better understood for the purposes of C accounting under the Kyoto Protocol. We investigated the impacts of three harvest residue management treatments on C and N stocks in a scoriaceous forest soil: whole-tree harvesting plus forest floor removal, whole-tree harvesting, and stem-only harvesting. Volumetric ...

The wealth of forests
The day I first set foot in a tropical rainforest, in Malaysia in the early 1980s, I experienced something profound. From the echoes of gibbons calling from the canopy in the early morning mist to the iridescent flash of a bird in a beam of sunlight, rainforests are a sensory delight as well as a marvel to anyone’s scientific curiosity. As I subsequently watched these forests dwindle and, ...

Group method of data handling (GMDH) in modelling of growth dynamics of trees irrigated with wastewater
This paper describes the formulation and analysis of growth dynamics models for trees irrigated with wastewater. The models can be used to obtain the characteristics of a species, depending on treatment conditions and climate factors, at all stages of growth. The experiments were carried out at the University of Patras to identify the characteristics (height rate and mortality) of the forest tree ...

Project - Green Thar (Rajasthan)
Rajasthan comprises mostly of the wide and inhospitable Thar Desert, facing low yields, scanty irrigation facilities, low fertility and high alkalinity of soil. In pursuit of creating lush green forest in middle of Thar, SankalpTaru is developing orchards of pomegranate and other fruit bearing trees by providing horticulture farming in the rural villages. This is enabling poor farmers to sustain ...

Opportunities to Generate Cash Flow for Family Forests Using Conservation Payments
There has been significant discussion about the merits of stacking conservation payments over the past few years. A simple explanation for credit stacking is when landowners are paid for conservation practices on their property that provide multiple benefits to the environment. Examples of credits types that might be stacked include: endangered species, water quality, wetlands, and carbon. ...

Why Our Buildings Should Be Made From Wood
If done correctly, using wood for buildings would have a number of environmental benefits without loss of biodiversity or carbon storage capacity. Although it may seem counterintuitive, it would be better if we built buildings from wood than from concrete, brick, aluminium and steel. We use millions of tons of these modern materials every year. They have many valuable properties, but are ...

Biomass harvesting: how forest thinning can help prevent wildfires
Every year, wildfires plague the nation. Once there’s an ignition source, dry foliage in country areas can quickly go up in flames, spreading through woodlands or grasslands quickly. While some wildfires can be small, others can be devastating and blaze through thousands of acres. While there’s no way to predict where wildfires may start, there are ways to minimize the damage of ...

Assessing agroforestry`s advantages
Agroforestry, the deliberate placement of trees into crop and livestock operations, can help capture substantial amounts of carbon on agricultural lands while providing production and conservation benefits. However, we currently lack tools for accurately estimating current and projected carbon values in these systems. In North America, windbreaks are an effective carbon-capturing option. Only ...

Climate and Economic Benefits of Agroforestry Systems
Introduction Agriculture is well known as a significant contributor to global greenhouse gas emissions, but emerging practices in land management have the potential to curtail these emissions and reverse much of the ecological and climate harm caused by overly intensive systems. One such practice, cultivation and conservation of trees in agricultural practices, or agroforestry, is an important ...

How can we create jobs, reduce food prices and boost economies?
The fate of heads of state across the globe is tied in large part to their ability to ensure employment, economic growth, and access to cheap food and clean water. Rising food prices have helped topple dictators across the Middle East. Europe, the United States, Japan and other major economies are spending trillions of dollars to restore growth and jobs. Too often, efforts to address ...

Find and Monitor Tree Crops for Sustainability
We can monitor agricultural production around the globe using satellites. Recently, there has been an increase in the number of satellites and the frequency and resolution of images being captured. Such large amount of data on a daily and weekly basis can be used with AI to detect crops. Current Best Practices Supply chain companies use manual scouting and surveys up to three times a season ...

Deer eating your plants? Tips for solving deer problems:
‘Deer’ can refer to any one of almost a hundred different species spanning the globe. The most common species in the U.S. are the white-tailed deer (in the east, southeast and Midwest) and the mule deer out west. Deer numbers have increased considerably since man has virtually eliminated their major predators. Suburbs encroaching on formerly natural open areas, woods and farm ...

Can superfoods boost the planet’s health, too?
As demand for African and Asian tree-based superfoods grows, researchers and entrepreneurs eye ways to maximize benefits for the environment. It can seem like new health food fads pop up every week — fads that often fade as quickly as they appear. Two gaining steam lately, though, may be worth a longer look: baobab and moringa. Traditional fare in parts of Africa (and for moringa, Asia as ...
