In recent years, many governments have intiated a process of recognising, regulating and linking up with primary animal health delivery systems that have been developed within rural communities. Others have been more cautious, deferring their decision until concerns about their safety, quality, impact, international credibility and sustainability can be clarified. This book uses both original research and studies by authors from a broad range of disciplines to critically examine each of those concerns. It equips those involved in livestock and veterinary policy to come to an informed judgement on the potential role of Community Based Animal Health Workers (CBAHWs).
