Impact of grazing densities,animal types,supplemental feedings on forest‐steppe pasture
The pastoral livestock production system carried on in natural open pastures in Mongolia has played a crucial role in the domestic economy.Socio‐economic reform included the introduction of a market economy, which was accelerated in the early 1990s, exerted a large influence on the system : the livestock population continued to increase ; it reached historical high 32.9 million in 1998 ; and the number of herders continued to increase in the 1990s.In the course of the changing, excessive grazing in natural pastures especially in and around centers was alarming as herders and livestock were more densely concentrated there than in other areas ( Enkhamgalan, 1995 ).These situations, which have continued until today, may demonstrate the decreasing sustainability of the production system.Then, JIRCAS and Mongolian State University of Agriculture have been conducting a project entitled.Development of a Sustainable Agro‐Pastoral System in the Dry Areas of Northeast Asia ( Apr 2006‐Mar 2011 ) to solve conflicting problems, such as pasture conservation, and increasing or maintaining the herdersincome.An experiment was started in/nearby the animal and human population center.This paper introduces the experiment, and some of its first‐year results are presented.
