A wood density and aboveground biomass variability assessment using pre-felling inventory data in Costa Rica
BACKGROUND The high spatio-temporal variability of aboveground biomass (AGB) in tropical forests is a large source of uncertainty in forest carbon stock estimation. Due to their spatial distribution and sampling intensity, pre-felling inventories are a potential source of ground level data that could help reduce this uncertainty at larger spatial scales. Further, exploring the factors known to ...
متن کاملSurvey of Directional Felling and Analysis of Effective Factors on Felling Error (Case Study; Iranian Caspian forests)
Economic and environmental logging is important for sustainable wood production in the Caspian forests, north of Iran. Predetermination of the skid trail network and directional felling is a usual recommended method to reduce logging impact. The aim of this study was evaluation of directional felling and finding factors effective on felling error. Totally 135 trees were selected randomly for di...
متن کاملI Monitoring Water Quality at a Food Waste Composting Site
In 1993, the Georgia Diagnostic and Classification Prison (located near Jackson, GA) initiated an on-site composting operation to convert food waste into a useable by-product. Each week, inmates compost about 20 tons of food waste, which are mixed with ground cardboard, hay, yard leaves, or wood products. The operation takes place on a 1.2-ha site (3 acres) that drains towards a small, paermial...
متن کاملOn Barriers to Institutional Composting and Commercial Composting Sustainable Development
Introduction During this research project, we attempted to identify and overcome barriers and resistance to the establishment of organic waste (leaf and yard waste and food waste) collection and diversion programs within public and private institutions in the region that generate large amounts of organic wastes. As only 2.4% of food waste (EPA 1997) is recovered or recycled, there is 97.6% of f...
متن کاملOn-site Composting of Restaurant Organic Waste: Economic, Ecological, and Social Costs and Benefits
On-site composting is examined as an alternative method of organic waste disposal in San Francisco Bay Area restaurants. Since 74% of an average restaurant’s waste stream is compostable material, composting and reuse of organic material would redirect a significant portion of the waste stream from landfills. Economic, ecological, and social costs and benefits of three methods of organic waste d...
