TLDR
In this paper, the authors show that the direction of land use change depends on the production zone in which it takes place, and that land in distant rainfed agropastoral zone is disintensified through land abandonment and an increase of the fallow period, land in nearby irrigated agropasteoral zone are intensified through more frequent cropping, and the use of high-yielding potato varieties, fertilizers, and pesticides.Abstract:
Farmers in the Upper Canete valley have both disintensified and intensified land use. The direction of land use change depends on the production zone in which it takes place. Although land in the distant rainfed agropastoral zone is disintensified through land abandonment and an increase of the fallow period, land in the nearby irrigated agropastoral zone is intensified through more frequent cropping, and the use of high-yielding potato varieties, fertilizers, and pesticides. Simultaneous intensification and disintensification contradicts Boserup's theory of agricultural intensification, which predicts unilinear change for all land use systems within a village territory. Population has decreased in the Upper Cante valley, but this factor alone cannot explain the dynamics of land use. Land use change is also driven by differences and complementarity between production zones, their distance from the villages, and social, economic, and technological change.read more

Quantifying the expression of potato genetic diversity in the high Andes through growth analysis and modeling
TL;DR: A comparative growth analysis of nine genotypes was conducted to describe their performance under the prevalent conditions in the high Andes, demonstrating the adequacy of the model, which explained more than 82% of the variations in growth parameters.

The conditions of agricultural growth
TL;DR: In this paper, Boserup argues that changes and improvements occur from within agricultural communities, and that improvements are governed not simply by external interference, but by those communities themselves using extensive analyses of the costs and productivity of the main systems of traditional agriculture.

Smallholders, Householders: Farm Families and the Ecology of Intensive, Sustainable Agriculture
TL;DR: The authors argues that the practice of small-holders is more efficient and less environmentally degrading than that of industrial agriculture which depends heavily on fossil fuel, chemical fertilizers, pesticides and herbicides.
