| 英文摘要 | This study sought to understand why and how the area of irrigated agriculture in Janos County, in northwestern Chihuahua, Mexico, has tripled since 1987. Expansion of agricultural frontiers has often been attributed to state policies and programs or von Thunian land-rent dynamics. Here, a political ecology approach relying on qualitative interviews with landowners was used to understand the drivers and patterns of conversion from native rangeland to crops. Results show that socioeconomic patterns of agricultural frontier expansion evolved over time, with different drivers at different phases. State policies, especially the land reform, were initially important for settling the agriculture frontier in small farms. Subsequently, economic differentiation, intensification, and growth of existing farms drove expansion. Since 2010, expansion has been driven by investment-oriented land purchases by absentee owners and larger-than-family farms. The Janos case details what may be common but underappreciated temporal dynamics at agricultural frontiers. |
