- Abstract:
- ... Plant phenology—timing of seasonal life cycle events—is a primary control on ecosystem productivity. Phenology data can be used to design better management systems by adjusting the timing of grazing or managed burns relative to growth stages of key species and planning restoration activities, such as targeted grazing. Tower-mounted digital cameras (phenocams) provide a cost-effective way to collec ...

- Abstract:
- ... The response hierarchy of “Avoid > reduce > reverse” is increasingly acknowledged as the best strategy for prioritizing actions designed to address land degradation at hectare to national scales. This hierarchy is based on the assumption that the economic return on investment (ROI) will usually be higher for actions that help avoid degradation than for those required to restore already degraded la ...

- Abstract:
- ... Much of the confusion about the definition of reference conditions for land health and degradation assessments is due to differences in policy and management objectives. Selection of a historic reference where it is not necessary, such as in the definition of future land degradation neutrality, can add significant cost and uncertainty to land management projects that require some knowledge of the ...

Monitoring wind erosion is needed to inform management, with explicit monitoring objectives being critical for interpreting and translating monitoring information into management actions. Monitoring objectives should establishquantitative guidelines for determining the relationship of ...

- Abstract:
- ... As global food demand continues to grow, private landowners and agricultural managers have increased incentives to convert grasslands to expand crop production. These conversions are increasingly occurring on marginal soils susceptible to rapid degradation, which threatens delivery of diverse bundles of ecosystem goods and services (EGS). A growing number of studies have demonstrated that previous ...

We address this uncertainty by evaluating the application of ecological site concepts and state-and-transition models (STMs) for detecting and quantitatively describing the impacts of land cover change on wind erosion. We apply a dust emission model over a rangeland study area in the ...

Soil health describes the ability of a soil to function at its potential, specifically “The capacity of a soil to function as a vital, living ecosystem that sustains plants, animals and humans”.

Within a climatic regime, topography, soil characteristics, and vegetation are expected to determine how the combined effects of precipitation, temperature, and evaporative demand of the atmosphere shape the spatial and temporal patterns of water within the soil profile and across a landscape. To forecast how desert landscapes may resp ...

Land degradation increases the vulnerability of agroecological systems to climate change and reduces the effectiveness of adaptation options. Yet these interactions have largely been omitted from climate impact assessments and adaptation planning. We examine how land degradation can influence climate‐change impacts an ...

- ... Adaptive management of road networks depends on timely data that accurately reflect the impacts those systems are having on ecosystem processes and associated services. In the absence of reliable data, land managers are left with little more than observations and perceptions to support management decisions of road-associated disturbances. Roads can negatively impact the soil, hydrologic, plant, an ...
