Abstract:
Sustainability of natural resources is currently a concern worldwide. The ecological and economic aspects of sustainability have received substantial research attention, but the social aspects of sustainability are less well understood. Participation by affected communities in natural resource management decisions is pivotal to social sustainability. As such, this study examined ten case studies of participation and decision-making by natural resource management groups involved in agriculture in the south-west of Australia.

Abstract:
This study aims to explore the challenges that face land use and land management in the context of the new South Africa. Approached from the African traditional religious angle the study will propose, among others, a new approach to land management and land designation. The study draws insights from literature on religious meaning of land and interviews conducted with two African traditional healers from two different black communities. The study introduces a new concept in land management, the concept of sacred space. (114-120 pages missing)

Abstract:
Rich fens are calcareous and nutrient poor wetlands with a rich flora of orchids, sedges and mosses. As many as one hundred plant species are rich fen specialists. Many wetlands have been drained historically, and transformed to agricultural land or production forests. Today rich fens cover only 2-3% of the total mire area in Sweden. Rich fen is a rare and valuable habitat also from a European perspective and is protected in the Natura 2000-network. To increase and maintain the biodiversity and ecosystem services rich fens can offer, it is important to increase the rich fen area by restoration

Though these flooding events affect many cities across the globe, it is often the less fortunate who are disproportionately impacted by such events. There are many factors as to why this is the unfortunate case, with a high number of the underprivileged urban population finding themselves living in informal settlements.

The management of natural resources entails the social construction of geographical space. Within the EuroAmerican tradition, these constructions have involved not only the definition of spaces but also the delineation of boundaries. The process of spatial construction and boundary delineation, when it includes contests among competing interests, or when it entails situations of dominance and resistance, engenders relations of power. The power relations most often take place within the realm of social, political, and economic discourse and practice. The outcomes of these power relations are le

However, existing methods for calculating carbon storage do not explicitly account for differences in carbon stored by different species of trees.

Abstract:
Agricultural landscapes provide our society with many benefits. While food production is the primary role of these landscapes, sociocultural and ecological benefits are also provided. However, the full scope of benefits that we obtain from agricultural landscapes are not always taken into account, and with the intensification of agricultural activities, more complex multifunctional landscapes are converted into simpler and less-functional landscapes. I used a heterogeneous agricultural landscape, the Champlain Valley of Vermont, as a case study to examine the interactions between landscape str

Abstract:
National parks have famously been called "America's best idea" and preserve the nation's natural and cultural resources for the enjoyment of all. One of the current working priorities of the National Park Service (NPS) is enhancing the relevancy and engagement of the national parks with diverse audiences, especially for underserved groups. To address this priority, transportation is needed to provide access to national parks, but transportation may not be equally accessible to all groups in society. Understanding the effects of transportation on visitation to the national parks by racial/ethni

Abstract:
An important aspect of forest management is the promotion of natural regeneration of commercial timber species.  To explore the potential of tree selection processes that consider species requirements for regeneration, I developed an approach to select trees to be retained as seed trees and to be felled alternative to a conventional system.  The commercial species were characterised for attributes relevant to tree selection.  The alternative approach developed to retain seed trees consisted in to retain 10-30% regarding to seven ecological attributes.  The conventional consisted of 10% retenti

Abstract:
Dans un contexte de socialisation des risques, les propriétaires et gestionnaires d’espaces naturels sont confrontés à un paradoxe opposant l’exigence croissante d’un aménagement des sites en vue de leur sécurisation, et la nécessité d’assurer leur préservation. Cette problématique revêt un relief particulier dans les espaces naturels littoraux, qui concentrent des sites d’exception en termes de biodiversité et de paysages, qui sont dans le même temps prisés des touristes et sportifs, et entourés par l’urbanisation. La gestion naturaliste de ces espaces génère des risques, voire des dommages,

Abstract:
As the demand for freshwater resources increases due to increasing human populations, degradation of available resources, and climatic changes it will become increasingly important to understand the factors that impact the physicochemical characteristics of surface water resources over space and time. This study assessed a headwater stream over the course of a year in the San Bernardino National Forest that serves as both surface and groundwater resources for the Santa Ana River Watershed region, the largest and most populated watershed in Southern California. Streams were monitored bi-weekly

Abstract:
The risk of spread and establishment of invasive species to interior habitat within urban parks is of great concern to park managers and ecologists. Informal trails as a vector for this transmission are not well understood. To characterize effects of informal trails on understory plant communities, I conducted a study of the informal trail network in Forest Park, Portland, Oregon. The system of 382 informal trails was mapped and evaluated qualitatively, and from this population a systematic sample was selected for analysis. To identify hotspots of informal trail activity, showing the relations

Full text
Abstract:
The Service Path Attribution Network (SPAN) framework provides a novel, user-centric, connectivity-based approach to ecosystem service assessment and valuation (ESAV). Ecosystem services are delivered to users through the simulated flow of some service medium (i.e., matter, energy, or information) from the ecosystems in which it originates (sources) to the people or assets which it affects (users). Along the way, the service medium may be absorbed by intervening landscape features (sinks) or captured by rival users. Crucially, the service medium is not itself an ecosystem service or benefit bu
