    Land use changes often lead to soil erosion, land degradation, and environmental deterioration. However, little is known about just how much humans accelerate erosion compared to natural background rates in non-agricultural settings, despite its importance to knowing the magnitude of soil degradation. The lack of understanding of anthropogenic acceleration is especially true for arid regions. Thus, we used 10Be catchment averaged denudation rates (CADRs) to obtain natural rates of soil erosion in and around the Phoenix metropolitan region, Arizona, United States.

    Globally, agricultural soils are being evaluated for their role in climate change regulation as a potential sink for atmospheric carbon dioxide (CO2) through sequestration of organic carbon as soil organic matter. Scientists and policy analysts increasingly seek to develop programs and policies which recognize the importance of mitigation of climate change and insurance of ecological sustainability when managing agricultural soils.

    Intensive silviculture is practiced in many parts of the world but is rare in the public forests of western Canada. Here, we make the argument that intensive silviculture could be justified in Alberta but has not been implemented due to philosophies and policy decisions by foresters from government, industry and academia. These include adherence to long rotations, management goals that are aimed at sustained total volume yield rather than economic value, limitations in the types of stands that are allowed to be regenerated and models that do not include intensive silviculture options.

    Community orchards could play a valuable role as nature-based solutions to complex challenges we face today. In these unique plantings, a variety of nut- and fruit-producing trees and berry shrubs are often established together on public spaces to provide the community with healthy, fresh food. Interest in these plantings has been increasing in the United States, even more so since the COVID-19 pandemic highlighted vulnerabilities in our food systems. However, the roots of community orchards can be traced back to Indigenous foodways which have persisted for millennia.

    Land use and land cover change (LULC) is an essential component for the monitoring environmental change and managing natural resources in areas of high natural and cultural biodiversity, such as the Amazon biome. This study was conducted in in the northern Amazon of Ecuador, specifically in the Diversity and Life Zone (DLZ) of the Yasuní Biosphere Reserve (YBR). The general aim was to investigate the territorial dynamics of land use/land cover changes to support policies for environmental and sociocultural protection in the DLZ.

    Habitat conservation banking is a policy instrument for conserving endangered species by providing financial incentives for the landowners in the United States. This policy instrument aims to protect habitat, but little or no thought has been given to its financial performance. A financial analysis of habitat conservation banks (HCB) informs policymakers and conservation biologists of the long-term success of this policy and the future of HCBs. This paper evaluates 26 habitat conservation banks (HCB) in California by calculating their Net Present Values (NPV).

    The ecosystem services concept has emerged as a guiding principle in natural resource management over the past two decades, and an ecosystem services approach to management is currently mandated as a core element of United States National Forest planning. However, the concept of ecosystem services has been interpreted and operationalized in a variety of ways, leaving a pronounced knowledge gap regarding how it is understood and implemented in different contexts.

    Land degradation is a global issue receiving much attention currently. In order to objectively reveal the research situation of land degradation, bibliometrix and biblioshiny software packages have been used to conduct data mining and quantitative analysis on research papers in the fields of land degradation during 1990–2019 (data update time was 8 April 2019) in the Web of Science core collection database. The results show that: (1) during the past 20 years, the number of papers on land degradation has increased.

    Landscape architecture programs in the United States are assessed based on the quality of the professional education received by their students. Research is becoming an increasingly important part of the profession as evidence-based landscape architecture grows, and it is critical that university faculty provide information that can be used in professional practice to resolve important environmental and social issues.
