Rural Development Trends and Land Use Policy in Colorado: Contributors to Habitat Fragmentation?

Fragmentation of wildlife habitat is a primary driver of global species decline. A major contributor to habitat fragmentation in the United States is rural residential development. Rural development in Colorado is occurring at rates far greater than the national average. Additionally, the lack of state-level planning control coupled with a lack of comprehensive, effective planning tools at the local level creates conditions that contribute to habitat fragmentation in many rural counties. Greater oversight and involvement in land use planning is needed by the state level to assist county governments. This study provides five recommendations to strengthen Colorado state land use policy in order to reduce habitat fragmentation.

Land use practices near tributary rivers and their influence on duckweed (Lemna obscura) bloom in the southern part of Lake Maracaibo, Venezuela: Sustainable solutions to address the issue

This study examined the relationship between land-use practices near tributary rivers in South Lake Maracaibo and the appearance of duckweed (Lemna obscura) in the lake. Four rivers were studied: The Mucujepe, Capaz, Guamo and Frio. Eight factors were assessed: rivers, sediments, erosion, soils, fertilizers, water quality, land use activities and vegetation corridors. Satellite images, official cartography, field visits and observations, water samples and personal communication with organizations involved were held to get an accurate and current assessment of the conditions. The study revealed the land-use practices surrounding the Pan-American Zone Rivers contribute to the duckweed blooming in Lake Maracaibo.

Onsite Wastewater Model Performance Code Implementation Plan

As the population of Colorado continues to grow, the impacts from individual sewage disposal systems, or onsite wastewater systems (OWS), are becoming more apparent. Increased use of OWS impacts not only water quality but land use and development as well. These impacts have led to the need for a new generation of wastewater regulations in the state, a transition from the historic prescriptive requirements to a more progressive, performance-based system. A performance-based system will allow smarter growth, improved water quality, and cost savings for both the regulatory agencies and the OWS industry in Colorado. This project outlines the challenges and essential elements required to make this transition, and provides guidance on how to meet the challenges and overcome barriers to implementing a performance code in Colorado.
