From the office to the field: Areas of tension and consensus in the implementation of the National Environmental Policy Act within the US Forest Service

Journal Articles & Books
Diciembre, 2010

We conducted an online survey (n = 3321) followed by five focus groups with Forest Service employees involved in compliance with the National Environmental Policy Act (NEPA) to explore agency views of how NEPA should be implemented within the agency. We filter these perceptions through the lenses of different functional groups within the agency, each with its own role in agency compliance with NEPA and its own suite of perceived accountabilities.

Effects of landscape protection on farm management and farmers' income in Norway

Journal Articles & Books

Noruega

Protected Landscapes (PLs) are increasingly used in Norway to conserve cultural (human modified) landscapes. In many cases the maintenance of agricultural activities in PLs is required to preserve landscape character. Whilst research exists on land conservation policies in general, the particular effects of PL on management and adjustment of the farms involved have not received attention in the literature. We present results from a questionnaire sent to owners of agricultural land within PLs in Norway.

Collective management on communal grazing lands: Its impact on vegetation attributes and soil erosion in the upper Blue Nile basin, northwestern Ethiopia

Etiopía

Collective action, on communal grazing land, has evolved in the highlands of northwestern Ethiopia to mitigate the problems of feed shortage and land degradation due to overgrazing. The exercise is liked by farmers for improving the availability of natural pasture during the long dry season when other feed sources get depleted. However, large portions of the communal grazing lands are still managed under free grazing throughout the year.

method for assessing work productivity and flexibility in livestock farms

Changes affecting livestock farming systems have made farm work a central concern for both the sector and for farmers themselves. Increased pressure on farms to be competitive and productive together with farmers’ demand for greater autonomy, holidays or time to spend on private activities and the family converge to underline the two key dimensions of work – productivity and flexibility – required for the assessment of work organization.

Assessing biodiversity conservation conflict on military installations

Journal Articles & Books
Diciembre, 2012

Conflict over endangered species conservation on military lands is becoming increasingly important as militaries attempt to balance an increased operational tempo with endangered species conservation. Successfully managing this conflict has major implications for biodiversity conservation given the US military alone manages over 12 million ha of land providing habitat to hundreds of at risk species, 24 of which are endemic to military installations.

Measurement methods on pastures and their use in environmental life-cycle assessment

Grassland agriculture plays an important role for livestock production and land management throughout the world. It is challenging to estimate the available feed on pasture plots. For this study, a rising plate meter was calibrated in swards of the organic experimental station of Trenthorst in northern Germany to calculate grazing intake of cattle and to determine biomass regrowth.

Accuracy and cost of models predicting bird distribution in agricultural grasslands

Journal Articles & Books
Diciembre, 2010

Numerous agro-environmental indicators have been developed to assess the impact of farming systems on biodiversity. They can be combined into logistic models for predicting the presence of species of ecological interest. In general, several models are available for a given species and their practical value depends on their accuracy and the cost of measurement of their input variables.

Willingness of Iowa agricultural landowners to allow fee hunting associated with in-field shelterbelts

Journal Articles & Books
Diciembre, 2009

In 2004, four focus groups consisting of agricultural landowners were organized in Northcentral Iowa to assess opportunities for hunting along in-field shelterbelts and on adjacent lands. A majority of respondents (95%) allowed/practiced some hunting on their lands. About 55% of respondents indicated that the potential existed for developing a fee hunting market associated with in-field shelterbelts.

Security and equity of conservation covenants: Contradictions of private protected area policies in Australia

Private land conservation is becoming a popular policy approach, given the constraints of increasing public protected areas, which include reduced availability of land for purchase, insufficient budgets for acquisition, and escalating management costs of small, isolated reserves. Conservation covenants represent a common policy instrument, now prominent in the United States, Canada and Australia, employed to compliment the protected area network.

Local innovation in a global context: documenting farmer initiatives in land husbandry through WOCAT

Innovation by farmers in land husbandry was the focus of the project Promoting Farmer Innovation (PFI), which was operational in Kenya, Tanzania and Uganda from 1997 to 2001. One of the project's final activities was to document best-bet innovations. It was decided to make use of a questionnaire available under the World Overview of Conservation Approaches and Technologies (WOCAT) to collect data on a selection of these technologies. Data were fed back into WOCAT's global database.

yield gap of global grain production: A spatial analysis

Journal Articles & Books
Diciembre, 2010
Global

Global grain production has increased dramatically during the past 50years, mainly as a consequence of intensified land management and introduction of new technologies. For the future, a strong increase in grain demand is expected, which may be fulfilled by further agricultural intensification rather than expansion of agricultural area. Little is known, however, about the global potential for intensification and its constraints.
