-Land changes are results from complex social and biophysical systems and their interactions (Turner et al., 1995). Such interactions result from processes that act on different hierarchical levels. At the global scale, the national and international commodities market (beef, grains and timber) drives demand for land change. This way, these changes cannot be adequately understood without knowing their linkages to decisions and structures made elsewhere. In this sense, understanding the role of networks is essential to understanding land-use structure. Such networks can be physical, such as infrastructure networks, and logical ones, such as market chains, linking a certain location to distant consumption or influential sites.  
  
-In general, a network is a set of items, which we will call vertices or sometimes nodes, with connections between them, called edges. Examples include the World Wide Web, social networks of acquaintance or other connections between individuals, organizational networks and networks of business relations between companies. In Newman, the author reviews some work on the structure and function of networked systems as network metrics <explain some the network metrics>.+Land changes are results from complex social and biophysical systems and their interactions (Turner et al., 1995).

At the global scale, the national and international commodities market (beef, grains and timber) drives demand for land change.

 +A network is a set of items, which we will call vertices or nodes, with connections between them, called edges. Networks exist everywhere and at every scale and can be physical, such as infrastructure networks, and logical ones, such as market chains, linking a certain location to distant consumption or influential sites. Several works argue that networks are important tool to describe complex systems, REFS. <gpm>

 +We believe which networks can be a important tool to link the actor of land change to global scenarios, as market and police public in land change modeling. However, is necessary to solve some specific challenges:
