This report describes work undertaken on the classification and characterization
of livestock production systems within the framework of the Global Study on Interactions
between Livestock and the Environment - Global Prospects and Perspectives coordinated
by FAO, the World Bank and USAID. Dr. Amir Kassam, TAC Secretariat, contributed
his extensive expertise on the agroecozone classification of the world. Mr. Jan
Groenewold assisted throughout the study with computations and searched empirical
data on systems' distributions across the globe. Ms. Gabriela Couto also helped
in the lengthy computational procedures. Ms. Christine Ellefson-Tavella undertook
the laborious editorial work. The inputs of many others within and outside FAO,
who reviewed drafts and contributed to the discussions are gratefully acknowledged.
