Combining the socio-economic-cultural implications of community owned agroforestry: The Winnebago Tribe of Nebraska

Abstract

Agroforestry systems usually are examined for their biological components and somewhat for economic feasibility but rarely for their sociocultural merits. A relatively young agroforestry system was examined in view of sociocultural, biological, and economic factors through the use of decision matrices. Decision criteria were used to evaluate an agroforestry system against two alternative landuse options, a corn-soybean rotation and renting the land to an agricultural producer. Economic, sociocultural, environmental, and risk criteria were considered simultaneously with a scaled Z-statistic and then compared by using four weighting schemes. When all criteria were weighted equally, the agroforestry system had the greatest Z-score (3.4), indicating the better alternative. Placing weights on economic criteria resulted with renting the land being the best alternative (Z-score 6.6). When sociocultural factors were weighted alone, or when greater weights were placed on sociocultural factors along with moderate weights on economic and risk factors, or when community weighted objectives were used, the introduced agroforestry system had the greatest Z-scores (11.5, 6.3, and 1.1, respectively). Use of weighted decision criteria allowed for sensitivity analysis between alternatives to be explored. This is especially important when using techniques that have a greater emphasis on economic parameters that are not equally important or appropriate cross-culturally. Use of decision matrices provides a more comprehensive method for comparing the multiple, interactive, and long-term benefits of the agroforestry system and competing land uses.
