| As the third paper in our three-part series on Wisconsin brownfields, this paper reports the results of a survey on the objectives of brownfields redevelopment, constraints to the redevelopment, the role of the state's Department of Natural Resources (DNR), and institutional controls. The 260 survey respondents include elected officials, staff from economic development and planning agencies, attorneys, private sector representatives, and professionals at nonprofit organizations. We find that: 1) respondents value both economic and environmental gains associated with brownfields redevelopment; 2) the high costs of cleanup are the principal barrier to brownfields redevelopment; 3) no single factor stands out as constraining DNR's ability to oversee cleanups;... |

| More than three-quarters of Mexico's coffee is grown on small plots shaded by the existing forest. Because they preserve forest cover, shade coffee farms provide vital ecological services including harboring biodiversity and preventing soil erosion. Unfortunately, tree cover in Mexico's shade coffee areas is increasingly being cleared to make way for subsistence agriculture, a direct result of the unprecedented decline of international coffee prices over the past decade. This paper summarizes the key findings of a three-year study of deforestation in Oaxaca, one of Mexico's prime regions for growing shade coffee. First, we find that deforestation during the 1990s was significant. Second, the loss of tree cover can likely be slowed by promoting... |

| Managed forest ecosystems-agroforestry systems in which crops such as coffee and bananas are planted side-by-side with woody perennials-are being touted as a means of safeguarding forests along with the ecological services they provide. Yet we know little about the determinants of land cover in such systems, information needed to design effective forest conservation policies. This paper presents a first-ever spatial regression analysis of land cover in a managed forest ecosystem-a shade coffee region of coastal Mexico. Using high-resolution land cover data derived from aerial photographs, along with data on the institutional, geophysical, socioeconomic, and agronomic characteristics of the study area, we find that plots in close proximity to urban centers... |
