Multiple sources of local knowledge: a global review of ways to reduce nuisance from the beneficial weaver ant Oecophylla
The weaver ants Oecophylla smaragdina and O. longinoda are abundant in tropical Asia, Australia and Africa. Although local people and a handful of scientists appreciate the benefits these tree-dwelling ants bring in terms of medicinal and food source, protection of tree crops, and enhancement of fruit and nut quality, Oecophylla has one major drawback: it also bites people. Perception of this ...

Earth out of sync rising temperatures throwing off seasonal timing
A newly hatched chick waits with hungry mouth agape for a parent to deliver its first meal. A crocus peaks up through the snow. Rivers flow swiftly as ice breaks up and snows melt. Sleepy mammals emerge from hibernation, and early frog songs penetrate the night. Spring awakening has long provided fodder for poets, artists, and almanac writers. Even for a notoriously fickle time of sunshine, ...

The socio-cultural impacts of economic changes to matrilineal Garo society in Bangladesh
An extension of the Garo hill towards south in Bangladesh along the mid-northern boundary with India is inhabited by a hill tribe called the Garo. They have a distinctive socio-economic background and culture. Their way of life has its origin in the uniqueness of the physiographic characteristics of the area which impelled them to live in isolation for long. But recently, with the initiation of ...

Impacts of fertilization on water quality of a drained pine plantation: a worst case scenario
Received for publication December 8, 2008. Intensive plantation forestry will be increasingly important in the next 50 yr to meet the high demand for domestic wood in the United States. However, forest management practices can substantially influence downstream water quality and ecology. This study analyses, the effect of fertilization on effluent water quality of a low gradient drained coastal ...

A methodology to estimate the future extent of dryland salinity in the southwest of western Australia
Received for publication January 27, 2009. In the southwestern agricultural region of Western Australia, the clearing of the original perennial vegetation for annual vegetation-based dryland agriculture has lead to rising saline groundwater levels. This has had effects such as reduced productivity of agricultural land, death of native vegetation, reduced stream water quality and infrastructure ...

Methane flux in cropland and adjacent riparian buffers with different vegetation covers
Received for publication September 12, 2008. While water quality functions of conservation buffers established adjacent to cropped fields have been widely documented, the relative contribution of these re-established perennial plant systems to greenhouse gases has not been completely documented. In the case of methane (CH4), these systems have the potential to serve as sinks of CH4 or may provide ...

Responsibility for the forest in Cote d'Ivoire: where are we now?
Forest management in Cote d'Ivoire has been completely revised over the past 20 years with the introduction of joint management and the sustainability approach. However, the policies implemented so far have shown themselves to be wanting in terms of conservation. They have run into problems linked to a lack of effectiveness, and a failure to give secure land tenure to peasants. To make these ...

Greenhouse impact of fossil, forest residues and jatropha diesel: a static and dynamic assessment
Biofuels have been recognised as one option for mitigating climate change. However, in order to show the sustainability of biomass-based fuels, an assessment of the savings in Greenhouse Gas (GHG) emissions compared to fossil fuels needs to be clearly shown. There are two ways to measure the greenhouse impact of an activity. It can be done statically or dynamically, by using Global Warming ...

Forest value orientations of interest groups in three regions varying in importance of commercial forestry
Differences in forest value orientations of interest groups were studied in Southeastern Finland, the Mauricie in Quebec, Canada and Central Labrador in Canada. The comparison is based on the idea that the current state of the forest, which reflects among other differences in the history of forest use of the area, interacts with people's forest values. The objective was to study whether people's ...

Preserving Russia's carbon sink: strategies for improving carbon storage through boreal forest protection
The boreal forests of Siberia, which store 40000 million tons of carbon and account for 25% of all non-ocean carbon absorption in the northern hemisphere, play a critical role in maintaining global climate balance. Siberia's forests, however, are being destroyed and degraded at an ever-increasing rate. This paper discusses the impact of Siberia's forests on the global carbon cycle, and what ...

Thailand's disappearing forests: the challenge to tropical forest conservation
Despite the ever-increasing concern about their conservation, tropical forests in Thailand are undergoing depletion and degradation, because the government pursued a policy of increasing national revenue through commercial logging and forest encroachment for the expansion of commercial agriculture until the end of 1980s. The pace of deforestation was further accelerated by the ever-growing ...

Barley yield and nutrient uptake for soil amended with fresh and composted cattle manure
Limited research exists on the long-term effect of fresh (FM) versus composted manure (CM) from beef cattle on barley (Hordeum vulgare L.) yield and nutrient uptake. Barley was grown (1999–2007) as silage on an irrigated clay loam soil in southern Alberta where organic amendments and fertilizer were annually applied for 9 yr in the fall of 1998 to 2006. The treatments were three rates (13, 39, 77 ...
