Preface

This document is part of the study, Interaction between Livestock Production and the Environment, requested by a number of donor agencies and carried out under the supervision of FAO, World Bank, and U.S. A.I.D. The study is organized into the following nine agroecozone-production system combinations:

LGT	Livestock Grassland-based Systems in Temperate Zones and Tropical Highlands
LGH	Livestock Grassland-based Systems in Humid and Subhumid Tropics and Subtropics
LGA	Livestock Grassland-based Systems in Arid and Semiarid Tropics and Subtropics
MRT	Mixed Rainfed Systems in Temperate Zones and Tropical Highlands
MRH	Mixed Rainfed Systems in Humid and Subhumid Tropics and Subtropics
MRA	Mixed Rainfed Systems in Arid and Semiarid Tropics and Subtropics
MIT	Mixed Irrigated Systems in Temperate Zones and Tropical Highlands
MIH	Mixed Irrigated Systems in Humid and Subhumid Tropics and Subtropics
MIA	Mixed Irrigated Systems in Arid and Semiarid Tropics and Subtropics

Additionally, two landless (confined, nongrazing) livestock production systems are described:

LLM	Landless Livestock Monogastric Systems
LLR	Landless Livestock Ruminant Systems

This report is Volume III of Environmental Impact Assessment of Livestock Production in Grassland and Mixed Rainfed Systems in Temperate Zones (LGT and MRT) and Grassland and Mixed Rainfed Systems in Humid and Subhumid Tropic and Subtropics (LGH and MRH) (excluding Africa). It includes Grassland-based Systems in Humid and Subhumid Tropics and Subtropics (LGH). It was executed through contract TF/INT/599-001/DEN/AGAD of December 31, 1994, between Grazingland Management Systems, Inc. and The Food and Agricultural Organization of the United Nations.

The Report was written by:
