Measuring the 3-30-300 Rule to Help Cities Meet Nature Access Thresholds
Published: 2023-07-02
Subjects: Environmental Public Health, Environmental Studies, Epidemiology, Geography, Physical and Environmental Geography, Public Health, Social and Behavioral Sciences
The 3-30-300 rule offers benchmarks for cities to promote equitable nature access. It dictates that individuals should see three trees from their dwelling, have 30% tree canopy in their neighborhood, and live within 300 meters of a high-quality green space. Implementing this demands thorough measurement, monitoring, and evaluation methods. Seven data and processes exist to assess these [...]
A Perspective on Conservation and Development
Published: 2023-05-25
Subjects: Biodiversity, Community-based Research, Demography, Population, and Ecology, Environmental Studies, Geography, Nature and Society Relations, Physical and Environmental Geography
Since the industrial revolution, the predominant model of economic development has involved economies of scale and unsustainable exploitation of natural resources, leading to environmental degradation and the ongoing mass extinction of species. The environmental impacts of this development-for(the sake of)-development model led to biodiversity conservation efforts that can be described as [...]

Scully et al [1] in their recent contribution review and revise past life cycle assessments (LCAs) of corn-grain ethanol’s carbon (C) intensity to suggest that a current ‘central best estimate’ is considerably less than all prior estimates. Their conclusion emerges from selection and recombination of sector-specific greenhouse gas emission predictions from disparate studies in a way that [...]
Global economic and diet transitions drove Latin American and Caribbean forest change during the first decade of the century.

Latin America and the Caribbean (LAC) contain more tropical high-biodiversity forest than the remaining areas of the planet combined, yet experienced more than a third of global deforestation during the first decade of the 21st century. While drivers of forest change occur at multiple scales, we examined forest change at the municipal and national scales integrated with global processes such as [...]
