Forests, health and climate change
Forests are essential to our survival and well-being. Forests clean our air, our water, our soil and they regulate our climate, amongst many other things. Trees and forests are not always associated with urban landscapes. However, there too they provide invaluable, often invisible, services. Simply by acting as 'green oasis' in our concrete jungles, they offer recreation and health services for ...

Environmental impacts of community-based forest management in the Philippines
Community-based forest management (CBFM) is a major strategy in managing forest lands in the Philippines. Forest and land management activities implemented in CBFM project sites include management of tropical forests (enrichment planting, timber stand improvement or TSI and limited harvesting), rehabilitation of degraded lands (reforestation, assisted natural regeneration (ANR)) and agroforestry. ...

The role of natural purified humic acids in modifying Mercury accessibility in water and soil
Received for publication April 17, 2008. Contamination of soils with mercury can be a serious problem. It can be mobilized or stabilized by humic substances (HS) containing binding sites with reduced sulfur that can have different binding capacities for CH3Hg+ and for Hg2+. In this work we investigated the influence of different humic acids (HAs, extracted from lignite, compost, and forest soil) ...

Soil water recharge for grassed and forested land covers on the Oak Ridges Moraine, southern Ontario, Canada
Soil water recharge (R) below 1 m depth was estimated via a 1-d water balance for grasslands, hardwood stands and red pine plantations on the Oak Ridges Moraine (ORM) in southern Ontario, Canada. Annual R values (431–696 mm) were in the order of previous estimates for outcropping sands and gravels on the ORM (∼400 mm); however, they only partially supported hypothesized differences in R ...

Soil water reserve estimation and vegetation relationships in a Mediterranean sub-humid forested catchment
A simple water balance model was used to calculate soil water reserve in a Mediterranean forested catchment. The relationship between soil water reserve and leaf water potential and stem water content was analysed. The usefulness of these variables as plant water status indicators was tested. The analyses were developed with a seven-year-long database (2001–2007) in the case of soil water content ...

Soil CO2 efflux in uneven-aged managed forests: temporal patterns following harvest and effects of edaphic heterogeneity
AbstractForest management is expected to influence soil CO2 efflux (FCO2) as a result of changes in microclimatic conditions, soil properties, and root dynamics. We measured FCO2 during the growing seasons of 2003 and 2004 in both gap and non-gap locations within stands ranging from 0 to 10 years after the most recent harvest in a selection-managed northern hardwood forest in central Ontario, ...

Projection of future climate change impacts on nonpoint source pollution loads for a forest dominant dam watershed by reflecting future vegetation canopy in a Soil and Water Assessment Tool model
This study is to assess the future impact of climate change on hydrological behavior considering future vegetation canopy prediction and its propagation to nonpoint source pollution (NPS) loads. The SWAT (Soil and Water Assessment Tool) model was used for the assessment. For a forest dominant ChungjuDam watershed of South Korea, the MIROC3.2hires climate data of SRES A1B and B1 scenarios were ...

Cokriging spatial interpolation of soil water dependent repellency parameters determined with two different tests
The nonlinear behavior of water repellency (WR) with respect to soil water content (g) may be described by curve parameters derived from two widespread methodologies such as the water drop penetration time (WDPT) and molarity of an ethanol droplet (MED) tests. While the former measures WR persistence in terms of the infiltration time of a water drop sitting on the soil surface, the latter ...

Turning abandoned rice fields into mangroves
What do you do when mangroves fail to naturally recolonise abandoned rice fields in one of the most precious mangrove deltas of the world? Pieter van Eijk reports on a recent mission to Western Africa that paves the way for large-scale mangrove recovery through a so-called ‘ecological restoration’ approach. While small on a map, Guinea Bissau is one of the most sizeable mangrove ...

Tree Spades and Environment: trees and our world
This article in about the usefulness of trees. For our progress we need to cut them down, so we need to replace them at a higher rate to compensate the deforestation using everything we have, like tree spades and environment rules. Trees provide us lots of benefits. Even if you look through a window and see green trees outside, it can reduce your blood pressure, anxiety and stress of your mind ...

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 ...

Benefits of minimum tillage case study
In Hungary, the MARGINS project is being conducted near Lake Balaton - the largest lake in Central Europe. The lake is renowned for its beauty and wildlife. Its surrounding hilly landscape is covered with rich brown forest soil. This landscape is, however, prone to soil erosion -in particular, rills develop when soil is weakened by excessive tillage and exposed to intense rainstorms. If not ...
