Does Conservation Planning Matter in a Dynamic and Uncertain World?
We show that while comprehensive reserve network design is best when the entire network can be implemented immediately, when conservation investments must be staged over years, such solutions actually may be sub-optimal in the context of biodiversity loss and uncertainty
Land Use and Landscape Change in the Colorado Mountains Ii: a Case Study of the East River Valley
Rural land in the U.S. Rocky Mountains is being subdivided and developed for residential and commercial use at an unprecedented rate. In the East River Valley, Colorado, land ownership parcel size began to decline sometime during the last two decades after increasing for over a century-since the first European settlement. Roughly 20% of the private land in the valley has been divided into parcels smaller than about 45 acres (18 ha), parcels that cannot economicallysupport agriculture. Development in the valley has caused significant land-cover fragmentation, especially in aspen, meadow, mixed conifer, and sagebrush cover types. Increased rates of house construction, from 3% per year during 1964-1990 to 8% per year from 1990 to 1994, and the conspicuous- ness of new roads and houses on the valley slopes, have enhanced local perception of rapid landscape change. Residents\u27 concern over land use especially focuses on the creation of ranchettes -large-lot residential areas carved out of former cattle ranches-and on the community changes associated with population growth, absentee home ownership, and class distinctions between recent immigrants and long-time residents. This paper documents these changes in the ecological and social landscape of this rapidly developing mountain valley using landscape metrics and interviews of key residents

Spatial Analysis of the Land Use Mechanism in Urban Renewal Areas: A Case Study in Hong Kong
2014 International Conference on Construction and Real Estate Management: Smart Construction and Management in the Context of New Technology, ICCREM 2014, 27-28 September 2014A growing body of research has focused on a land use mechanism, which is the basis for making decisions and policies. Previous studies on an urban land use mechanism focused mainly on urbanization and urban sprawl, while urban renewal is often a neglected area. This research aims at analyzing land use mechanisms in urban renewal areas. The Kowloon District in Hong Kong was selected as the study area for urban renewal. Regression analysis has been applied to explore the relationships between different land use types and spatial land use factors. The relative operating characteristic (ROC) values indicate the effectiveness of regression analysis. The regression results give insight into a land use mechanism in an urban renewal area, which can be helpful input for land use management.Department of Building and Real Estat
