Towards a viable system for monitoring agrobiodiversity on-farm: A proposed new approach for Red Listing of cultivated plant species por Padulosi, S., Dulloo, Mohammad Ehsan

“…Monitoring of cultivated agrobiodiversity has, not surprisingly, received extremely poor attention by researchers so far. Reasons for that may include the sheer number of varieties of crop species on-farm, the diffuse presence of diversity, varying from large areas to small patches of land and home gardens, the dynamic nature of cultivation that deploys various crops and varieties in different ways, the absence of farmer based mechanisms to which to anchor a possible monitoring system, and important policy aspects, such as those related to access and use of information generated during the monitoring. …”

Evidence of differences in trypanosusceptibility in East African Zebu cattle por Rowlands, G.J., Mulatu, W., D'Ieteren, G.D.M., Nagda, S.M.

“…Despite a high prevalence of drug resistance, regular Berenil treatment appears to have maintained these cattle at reasonable levels of productivity. However, when corrected for frequencies of parasitaemia and treatment, there was significant associations between the PCV maintained by an individual and its productivity in terms of growth rate, calving interval or risk of abortion. …”
