The Pennsylvania Constitution contains a unique Environmental Rights Amendment (“ERA”) creating an individual right to “clean air, pure water, and to the preservation of the natural, scenic, historic and esthetic values of the environment.” The ERA also includes a public trust element...

This article provides a description and analysis of the dozen types of legal tools that are available to reduce U.S. greenhouse gas (GHG) emissions by at least 80% from 1990 levels by 2050. The “80 by 50” target and similarly aggressive carbon abatement goals are often referred to as “deep...

The issue of climate change has at long last made its way into mainstream policy discussions in the United States. However, the focus both in the United States and internationally has been on reducing energy production and transportation emissions. This has led the media, policy makers and the...

The study is geographically focused on the Manila Trench, located in the west Pacific Ocean, South China Sea, west Philippines. The research aims at the geological mapping, analysis and visualizing variations in the submarine geomorphology of the Manila Trench. Technically, the work was done...

Public trustees at the state, federal, and tribal level are tasked with ensuring that those responsible for destroying or damaging natural resources sufficiently compensate the public for its loss. Those trustees have the fiduciary duty to maintain and restore the natural resources within the...

Aquatic life water quality criteria are numeric or narrative descriptions of water quality that protect aquatic life from unhealthy water conditions. The Clean Water Act (CWA) requires the U.S. Environmental Protection Agency (EPA) to develop and, as necessary, revise “criteria for water...

Vegetation of Cameroon includes a variety of landscape types with high biodiversity. Ecological monitoring of Yaoundé requires visualization of vegetation types in context of climate change. Vegetation Indices (VIs) derived from Sentinel-2 multispectral satellite image were analyzed in SAGA GIS...

The study area is located in western Pacific Ocean, Mariana Trench. The aim of the data analysis is to analyze the potential influence of how various geological and tectonic factors may affect the geomorphological shape of the Mariana Trench. Statistical analysis of the data set in marine...

Cartographic visualization is a key means for the analysis of the Earth’s environmental processes. In view of the rapidly increasing multi-source data, cartographic approaches are updated accordingly. Mapping of countries characterized by complex geologic settings, such as Tanzania, requires...

Integrated mapping is essential in geological studies to assess risks of earthquake hazards. Cartographic techniques have become a commonplace approach to visualizing data in the continuous geologic and geophysical fields. However, traditional GIS mapping is a manual process with a...
