Past stereotypes of indigenous pastoralists as ignorant and environmentally destructive are being revised as ecological and social science research advances. As yet, little documentation of pastoralists' ecological knowledge exists, and even less is known about how this knowledge is, or can be, applied to resource management. This paper outlines the ecological knowledge of Mongolian nomadic pas...

Abstract DairyMod is a biophysical simulation model of the dairy pasture system. It has been designed to explore dairy pasture management and incorporates the principal rotational grazing management strategies that are used in Australia. It also includes full treatment of the fluxes of water and nutrients in the grazing system, and therefore it also has utility in analyzing changes in resource ...

Economic evaluations of the benefits of integrated weed management often only consider the benefits of management in the crop phase, and ignore the impact of rotational options. In particular, non-crop phases such as annual and perennial pasture phases can have a substantial impact upon weed population dynamics and economic returns. Moreover, extended perennial pasture phases are being promoted...

For 2 grazing seasons, effects of pasture size, stream access, and off-stream water on cow distribution relative to a stream were evaluated in six 12.1-ha cool-season grass pastures. Two pasture sizes (small [4.0 ha] and large [12.1 ha]) with 3 management treatments (unrestricted stream access without off-stream water [U], unrestricted stream access with off-stream water [UW], and stream access...

one of the main resonator factors in watershed soil erosion is inappropriateland management including conversion of pasture land to dry-land farming.unfortunately, the changes of gara su watershed usages have been very common.thus, in order to understand the influence of land use on runoff rate and soil loss, soillosses were investigated and determined under both pasture and dry-land agricultur...

This paper considers the potential problems that may militate against the adoption of organic poultry production in Nigeria. Factors identified include: higher risk of diseases like coccidiosis and Newcastle disease, disease prevention and control / herd health management, disease containment in times of outbreak, land acquisition (land tenure system), market economies / cost-benefit ratio, pas...

We analyzed how three different dairy management systems –continuous grazing, confinement and management intensive grazingcompare across nine sustainability indicators set by the Dairy Stewardship Alliance. A self-assessment survey comprising animal husbandry, biodiversity, energy, community health, farm financials, nutrient, pest, water and soil management was assessed twice across the same fa...

Increasing the current precision of nutrient management will need analytical tools that aid in collecting site specific data. A technology with potential is hyperspectral remote sensing. Modern, portable spectroradiometers permit reflectance data in the spectral region between 350 and 2500 nm to be collected quickly. With the limited sampling, handling, and processing required the technology al...
