Range management needs information on distribution of livestock. The better the distribution of the livestock, the more uniform the use of the rangeland. This study was conducted to record the path of the herd steering by the shepherd. A GPS was attached to a three year old ewe which was moving with the flock. The path of flock movement was recorded for three years on a monthly basis during the...
Concentrations and loadings (output, number day-' km-2) of fecal coliform (FC) indicator bacteria were measured from 1979 through 1984 in streamflow from 13 forested watersheds under the following range management strategies: (A) no grazing; (B) grazing without management for livestock distribution; (C) grazing with management to obtain livestock distribution, and (ID) grazing with management t...
The Egyptian vulture, Neophron percnopterus, as a globally endangered species, is significantly affected by conflicts with human, leading to the decline of this species population. Availability of food resources is known as one of the most important factors affecting the distribution of the Egyptian vulture. In this study, we employed an ensemble modelling approach to predict the suitability o...
مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...
The e¤cient operation of livestock markets is contingent upon producers accessing relevant market information which assists adjustment to production and distribution. This article provides an analysis of the value of market information gleaned by producers attending public livestock auctions. The article uses the Travel Cost Method to quantify the value of this information and notes the limitat...
Livestock predation by large carnivores and their persecution by local communities are major conservation concerns. In order to prevent speculations and reduce conflicts, it is crucial to get detailed and accurate data on predators' dietary ecology, which is particularly important in human dominated landscapes where livestock densities are high. This is the case of the endangered Iberian wolf i...
In livestock industries, reliable up-to-date spatial distribution and abundance records for animals and farms are critical for governments to manage and respond to risks. Yet few, if any, countries can afford to maintain comprehensive, up-to-date agricultural census data. Statistical modelling can be used as a proxy for such data but comparative modelling studies have rarely been undertaken for...
PREFACE This is the 11 th of a series of working papers prepared for the Intergovernmental Authority on Development Livestock Policy Initiative (IGAD LPI). The IGAD LPI was established by IGAD in collaboration with FAO and with financial support from the European Commission. Its main objective is to enhance the contribution of the livestock sector to sustainable food security and poverty reduct...
Changing land use patterns in southern Africa have potential to dramatically alter the prospects for carnivore conservation. Understanding these influences is essential for conservation planning. We interviewed 250 ranchers in Namibia to assess human tolerance towards and the distribution of large carnivores. Cheetahs (Acinonyx jubatus), leopards (Panthera pardus) and brown hyaenas (Hyaena brun...
