Preserving biodiversity can be compatible with intensive agriculture
Date:2/6/2013

UNIVERSITY PARK, Pa. -- Preserving genetically diverse local crops in areas where small-scale farms are rapidly modernizing is possible, according to a Penn State geographer, who is part of an international research project investigating the biodiversity of maize, or corn, in hotspots of Bolivia, Peru and Mexico.

Hotspots are areas where cultivation of peaches and other non-traditional crops has exploded over the past decade, noted Karl Zimmerer, professor and head of the Department of Geography, and where small-scale farms are often female-run and have been previously regarded as marginal to mainstream agriculture.

"Peach-growing in central Bolivia is a vitally important income-generating strategy, even while farmers also desire and succeed in producing their Andean maize, both for eating and seed, as well as some sale," said Zimmerer, whose findings were recently published in the Proceedings of the National Academy of Sciences.

The researcher analyzed small-scale farm, or smallholder, landscapes and their farming and livelihood practices, including labor migration and irrigation issues, from 2000 to 2010 over three areas within Bolivia's Valle Alto region. Farmers had low-to-moderate incomes by national standards.

Zimmerer and his colleagues surveyed land use among 174 smallholder households to assess production inputs and outputs of maize and peach crops. Among the factors they examined were farm-level management, varietal choices and water and soil management. Zimmerer designed this data collection and analysis to use with high-resolution satellite imagery and Geographic Information Systems. These techniques enabled him to create geographic models, maps and estimates of the areas devoted to intensified peach- and maize-growing.

Zimmerer also interviewed diverse groups of land users and officials to determine similarities and differences of perspectives on biodiversity in changing farming and food syst
