Smoke management of wildland and prescribed fire: understanding public preferences and trade-offs

Journal Articles & Books
Décembre, 2014
États-Unis d'Amérique

Smoke from forest fires is a serious and increasing land management concern. However, a paucity of information exists that is specific to public perceptions of smoke. This study used conjoint analysis, a multivariate technique, to evaluate how four situational factors (i.e., smoke origin, smoke duration, health impact, and advanced warning) influence public tolerance of smoke in the northern Rocky Mountains and south-central United States.

Agricultural land market in Poland and the European Union

Conference Papers & Reports
Décembre, 2013
Pologne
Lettonie

The aim of this study was to compare the agricultural land market in Poland and in the selected countries of the European Union. The present paper compares the price changes of agricultural land in Poland and the EU. This research contains the information on institutions involved in agricultural land management in the selected EU countries. The paper presents the current state of the Polish market and its prospects for the land. Therefore, the development of the agricultural real estate market in Poland covers the years from 2004 to 2012.

Fire and carbon management in a diversified rangelands economy: research, policy and implementation challenges for northern Australia

Journal Articles & Books
Décembre, 2014
Australie

Burning of savanna is a globally important source of greenhouse gas (GHG) emissions. In Australia, burning of savanna contributes between 2% and 4% annually of the nation’s reportable emissions. Complete removal of this source of emissions is unrealistic because fire is a ubiquitous natural process and important land-management tool. In the rangelands of northern Australia, fire is used to manage habitat for conservation, control woodland thickening, manipulate pastures for grazing and is an essential component of indigenous cultural and land-management practice.

Biosphere-atmosphere exchange of reactive nitrogen and greenhouse gases at the NitroEurope core flux measurement sites: Measurement strategy and first data sets

Journal Articles & Books
Décembre, 2009

The NitroEurope project aims to improve understanding of the nitrogen (N) cycle at the continental scale and quantify the major fluxes of reactive N by a combination of reactive N measurements and modelling activities. As part of the overall measurement strategy, a network of 13 flux 'super sites' (Level-3) has been established, covering European forest, arable, grassland and wetland sites, with the objective of quantifying the N budget at a high spatial resolution and temporal frequency for 4.5 years, and to estimate greenhouse gas budgets (N₂O, CH₄ and CO₂).

Influence of Diverse Values, Ecological Structure, and Geographic Context on Residents' Multifaceted Landscaping Decisions

Journal Articles & Books
Décembre, 2010

Previous research has examined the influence of values on human-ecological decisions, yet disparate approaches render inferences across studies difficult. In this paper, we present a robust conceptualization of values, encompassing general life values, broad-based environmental orientations, and specific yard priorities, while comparatively examining how these influence residents' land-management practices.

Grassland management options under Kyoto Protocol Article 3.4. The Portuguese case study

Journal Articles & Books
Décembre, 2012
Portugal

Portugal has voluntarily committed to reporting the CO2 emissions and removals resulting from grassland management under Kyoto Protocol Article 3.4. This commitment, together with the fact that a significant proportion of grasslands in Portugal are of low productivity and are located in the regions with higher risk of desertification, brought the context and motivation to promote the expansion of permanent sown biodiverse rich in legumes.

Socioeconomic changes and forestland development: commonalities and distinctions between the eastern and western United States

Journal Articles & Books
Décembre, 2010
États-Unis d'Amérique

Impacts of rural land development on natural resources in the United States have been well documented and research on rural land development provides important inputs to land conservation policy and program development. Although numerous land-use studies have been completed for the western and eastern states, still lacking is a single study examining changes in population, housing, and land development in the two regions.

Land and water management of tidal lowlands: Experiences in Telang and Saleh, South Sumatra

Journal Articles & Books
Décembre, 2010
Indonésie

Indonesia has available over 20 million ha of tidal lowlands. In their natural state these are generally waterlogged areas that may be regularly inundated for prolonged periods. Almost 4 million ha of these tidal lowlands have been reclaimed, partly by spontaneous settlers and partly by the government.

structured multi-stakeholder learning process for Sustainable Land Management

Journal Articles & Books
Décembre, 2012

There are many, often competing, options for Sustainable Land Management (SLM). Each must be assessed – and sometimes negotiated – prior to implementation. Participatory, multi-stakeholder approaches to identification and selection of SLM options are increasingly popular, often motivated by social learning and empowerment goals. Yet there are few practical tools for facilitating processes in which land managers may share, select, and decide on the most appropriate SLM options.

Carbon stocks and carbon fluxes from a 10‐year prescribed burning chronosequence on a UK blanket peat

Journal Articles & Books
Décembre, 2015

Prescribed burning is a common land management technique in many areas of the UK uplands. However, concern has been expressed at the impact of this management practice on carbon stocks and fluxes found in the carbon‐rich peat soils that underlie many of these areas. This study measured both carbon stocks and carbon fluxes from a chronosequence of prescribed burn sites in northern England.

What impact might mitigation of diffuse nitrate pollution have on river water quality in a rural catchment?

Journal Articles & Books
Décembre, 2012

Observations of river flow, river quality and solar radiation were collated to assess the degree to which light and nutrients may be limiting phytoplankton growth at seven sites in the River Ouse catchment in NE England under average conditions. Hydraulic information derived from river network model applications was then used to determine where river water has sufficient residence time above the tidal limit to facilitate bloom development. A nitrate model (NALTRACES) was developed to estimate the impact of land management change on mean river nitrate concentrations.
