Book Description
This paper examines the factors causing agricultural success or failure among colonists in the Transamazon Highway colonization project. A brief description of the project includes resons why, after only five years of operation, the focus of the project turned from small farmers to large agro-business or corporate development.

Book Description
This study is aimed at estimating carrying capacity for the human population in a portion of Brasil's Transamazon Highway colonization area a variety of assumptions. Special emphasis is given to the effect of variability in a number of factors related to agricultural production and comsumption. Carrying capacity is defined operationally in terms of a gradient of increasing probability of colonist failure with population density within a limited range of densities. Both the criteria defining a "failure" and the critical value for the maximum acceptable probability of colonist failure can be culturally defined. Multiple criteria, including both comsumption and environmental quality measures can be used. Failure probabilities for carrying capacity estimation aretaken to be sustainable over a long period of years. A computer simulation is developed which reproduces many features of the agroecossystem of which the colonists are a part, including sectors for agricultural production, resource allocation, product allocation, and population. Gradients of failure probabilities for the estimation of carrying capacity are constructed from information output by the simulations. Both deterministic and stochastic runs are made, allowing the assessment of the importance of variability. Variability in crop yields results in colonist failure frequencies based on a number of criteria which greatly exeed the goals of Brazilian planners, despite restrictions on the data set which tend to make simulation results over-optimistic.
