This paper aims to investigate the spatial patterns of livestock and poultry breeding in China. Using statistical yearbook and agricultural survey in 2007, the county-level populations of livestock and poultry are estimated as equivalent
clustering trends of the 3 indicators are examined respectively. Furthermore, the thematic map series (TMS) and related gravity centers curve (GCC) are introduced to explore the spatial patterns of livestock and poultry in China. As a result, the China’s
livestock and poultry breeding would be classified into 8 types : extremely sparse region, sparse region, relatively sparse region, normally sparse region, normal region, relatively concentrated region, concentrated region and highly concentrated region.
Shoreline erosion : a cautionary note in using small farm dams to determine catchment erosion rates
Data from 10 small dams in SE Australia show that shoreline erosion due to farmlivestock access to the dams can account for a significant proportion (up to 85%) of sediment contained in the dam. The volumes of sediment resulting from such shoreline
erosion may be of the same order as the volumes produced by gully erosion in the dam's catchments, prompting caution in using farm dams to which livestock have access to determine small catchment erosion rates. Other issues, related to the trap efficiency
, also mean that erosion estimates based on farm dam sedimentation should be treated with caution.

Human activities in the southern side of the Pyrenees have increasingly been concentrated in the valley bottoms. This shift has created strong competition among differing land uses : hay cultivation for livestock, road construction, tourist

The crucial feature of this study is the district-level analysis of all properties of over 1000 ha farmland. In addition to the farmland, the total areas of the farms, the livestock holdinds and the quality of their soil have also been analysed

The paper develops a spatial rural economy model of adaptation to rural change that accounts for a multitude of rural enterprises across a diversity of ecosystems in South America using household surveys. Adoptions of crops, livestock, forests
and both specialized and diversified enterprises are modeled. Livestock, forests, and a diversification into crops, livestock, and forests are key adaptation strategies. Adaptation behaviours are closely tied with ecosystem changes under global warming.
