We describe and label four types of monitoring—surveillance, implementation, effectiveness, and ecological effects—that are designed to answer very different questions and achieve very different goals. Surveillance monitoring is designed to uncover change in target variables over space and time; implementation monitoring is designed to record whether management actions were applied as prescribe...
Resource managers are increasingly engaging with tribes and first nations and looking for methods to incorporate their perspectives, priorities and traditional ecological knowledge (TEK) into public land and resource management. Many initiatives that engage tribes and their TEK holders only seek tribal input, such as biological data, that is most easily integrated into existing management struc...
Addressing environmental management problems at catchment scales requires an integrated modelling approach, in which key bio-physical and socio-economic drivers, processes and impacts are all considered. Development of Decision Support Systems (DSSs) for environmental management is rapidly progressing. This paper describes the integration of physical, ecological, and socio-economic components i...
Global environmental challenges require approaches that integrate biodiversity conservation, food production, and livelihoods at landscape scales. We reviewed the approach of conserving biodiversity on “high-nature-value” (HNV) farmland, covering 75 million ha in Europe, from a resilience perspective. Despite growing recognition in natural resource policies, many HNV farmlands have vanished, an...
This paper presents a theoretical framework for analyzing human-environment issues that examines shifting, dialectical relationships between social and power relations, cultural beliefs and practices, and ecological processes to allow an interdisciplinary, complex assessment of social and environmental change in Nepal. The purpose of this analysis is to capture the complexity and non-static nat...
wetlands as water resources have a special place in the semi-arid plateau of iran and boundary determination is necessary for their effective conservation and conflict resolution among stakeholders that are dependent on these resources. determination of the wetland boundaries should be commensurate with environmental features affecting on it which normally extend beyond water extent. ecological...
A mathematical policy model of oak woodlands is presented. The model illustrates the policy uncertainties that exist in the management of oak woodlands. These uncertainties include: (1) selection of a policy criterion function, (2) woodland dynamics, (3) initial and final state of the woodland stock. The paper provides a review of each of the uncertainty issues. The final section of the paper d...
The importance of developing multi-disciplinary approaches to solving problems relating to anthropogenic pollution is now clearly appreciated by the scientific community, and this is especially evident in boreal ecosystems exposed to escalating threats of petroleum hydrocarbon (PHC) contamination through expanded natural resource extraction activities. This review aims to synthesize information...
The purpose of this research was to investigate the interaction between the type of management approach and the type of combating desertification projects on soil fertility function and it is especially important in monitoring and evaluation of these projects. For this purpose, at the first, the range of three types of combating desertification projects including bush planting, constructing a c...
