    As marginal drylands, all project sites share similar environmental constraints such as recurrent droughts,
    water shortages, shallow soils and the threat of land degradation. As they occur in different economic,
    political, social and cultural environments, it will be interesting to address similar bio-physical problems
    from different perspectives stemming from varying anthropogenic factors. More importantly, the

    Parasitic nematodes, especially
    Haemonchus contortus,
    are among the most common and
    economically important causes of infectious
    diseases of sheep and goats owned by
    pastoralists and small holder farm
    ers in East Africa. In Kenya, control of these infections
    mainly relies on the use of anthelmintic dr
    ugs. However, ethnoveteri
    nary medicine (EVM)
    preparations are widely used by pastoralists
    and small holder farmers (SHF) for treatment
    of their livestock agains

    Con la finalidad de evaluar productividad, consumo y eficiencia biológica en vacas Frisón Neozelandés (FN) y F1 Jersey-Frisón Neozelandés a pastoreo, se emplearon 23 vacas FN y 24 F1, primíparas, paridas entre el 23/7 y el 27/9 de 2001, en la Estación Experimental Oromo, Universidad de Chile, X Región. La información se recopiló en tres períodos, de 21 días cada uno. Al inicio de estos, las vacas se encontraban en 66, 126 y 220 días de lactancia. Los animales fueron pesados diariamente con el fin de obtener el peso vivo (PV) promedio y la tasa de variación del peso.

    ACIAR funded a collaborative project between research organisations in Southeast Asia for ILRI and regional partners to explore new ways to control helminth parasites in the tropics. The project aimed to increase small ruminant production in Southeast Asia by controlling internal parasites, which are one of the major constraints to sheep and goat production in the tropics. Control of internal parasites also provides an avenue for general improvement in husbandry methods.

    Little of the current focus on landscape fragmentation has focused on rangelands or pastoral lands. This paper investigates the existing evidence for causes and processes of fragmentation in pastoral lands and its effects of landscapes and peoples. More conceptual work is needed on the definition of loss and fragmentation, particularly efforts to clarify fragmentation from whose (or what's) perspective.

    The objectives of this study were to: (a) estimate milk and beef yields obtained from cows grazing pastures in different stages of degradation; (b) estimate income losses as a result of the degradation process; (c) estimate the proportion of pasture areas found in each stage of degradation within the six administrative regions of Honduras; and (d) identify different strategies and costs to recuperate degraded pastures. Data came from two surveys executed during a workshop carried out in March 2004.

    The Ethiopian Boran cattle evolved from the Borana pastoralists’ successful breeding strategiesunder the harsh conditions of arid rangelands. At present two types of this breed are known toexist in the Borana rangelands: the Qorti, or the typical Boran, and the Ayuna, its local variantwith smaller body weight and lesser demands on pasture. This paper illustrates the impact ofexternal interference on the maintenance of the Boran cattle breed in its original habitat.
