Summary
Farm structure and land use in the Great Plains were influenced by farmer
Area of Science:
- Agricultural Economics
- Rural Sociology
- Environmental History
Background:
- Debate exists on whether farm extensification/intensification aligns with farmer life course and farm family cycles.
- Existing theories need validation within diverse agricultural development contexts.
Purpose of the Study:
- To test farm- and life cycle theories in the context of US Great Plains agricultural development (1875-1930).
- To analyze the relationship between family, farm, and land use patterns over time.
Main Methods:
- Utilized unique longitudinal data linking families to farms across 25 Kansas townships.
- Employed multilevel statistical modeling to account for environmental diversity and temporal trends.
Main Results:
- Farmer's age, household size, and structure significantly correlate with farm extent and land use intensity.
- Environmental variation, particularly aridity, was a primary determinant of farm structure.
- Findings support the simultaneous influence of life course and environmental factors on farm development.
Conclusions:
- Validates farm and life cycle theories in the historical context of the Great Plains.
- Highlights intergenerational motivations in farm development, including both sons and daughters.
- Emphasizes the critical role of environmental conditions in shaping agricultural systems.

Impact of Social Context on Individuals
Social psychology examines how the real or imagined presence of others influences individuals' thoughts, feelings, and behaviors. A key concept in this field is the role of social context in shaping behavior. The same individual may act differently depending on the social setting, due to the varying expectations and norms associated with each environment. This context-dependent behavior illustrates the influence of social roles, which prescribe appropriate conduct in specific situations.Social...
Habitat Fragmentation
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
Ecological Disturbance
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a forest...
Migration
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
Gene-Environment Interactions
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...
Dimensions of Health and Illness
The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.
