OBJECTIVES To describe the food environments experienced by American Indians living on tribal lands in California. METHODS Geocoded statewide food business data were used to define and categorize existing food vendors into healthy, unhealthy, and intermediate composite categories. Distance to and density of each of the composite food vendor categories for tribal lands and nontribal lands were...

Colonization of abandoned lands by woody vegetation may be a great opportunity for ecosystem recovery given the current and future trend of land abandonment. This may help to reverse the generalized condition of ecosystem degradation of developed countries which is an urgent need. However, ecosystem recovery in abandoned lands can be seriously limited by biotic and abiotic factors. Indentify su...

As the barren lands play a key role in the interaction between land cover dynamics and climate system, an efficient methodology for the global-scale extraction and mapping of the barren lands is important. The discriminative potential of the existing soil/bareness indexes was assessed by collecting globally distributed reference data belonging to major land cover types. The existing soil/barene...

The main objective of this study is to assess the spatio-temporal dynamics of land cover/land use changes in the lower Mekong Delta over the last 40 years with the coastal Tran Van Thoi District of Ca Mau Province, Vietnam as a case study. Land cover/land use change dynamics are derived from moderate to high spatial resolution (Landsat and SPOT) satellite imagery in six time intervals ranging f...

This forum manuscript examines the importance of grazing lands for sequestering soil organic carbon (SOC), providing societal benefits, and potential influences on them of emerging policies and legislation. Global estimates are that grazing lands occupy ,3.6 billion ha and account for about one-fourth of potential carbon (C) sequestration in world soils. They remove the equivalent of ,20% of th...

Cardiovascular disease is the leading cause of death for Native Americans. For several decades, the American population has fallen victim to poor nutritional habits, where healthy, natural foods have been replaced with unwholesome foods prepared with too much sugar, saturated fat and artificial additives. American Indian and Alaska Native populations have fared no better. Being forced onto rese...

Running across Enron Field during the Owls' baseball game on Friday seemed like a ha rmless prank to Jose De La Pena. But it laiided the Baker College senior in jail for the night, and he may face fines of up to $2,500. At the game, a group of about 25 Baker students, including De \ x Pena, along with Baker Master Mickey Quinones were sitting on the third base line. Quinones had purchased ticke...

Upper Blue Nile Basin, Ethiopia. This study was conducted at the Koga Irrigation Scheme in upper basin (Ethiopia) to investigate influence of irrigation activity on groundwater system. Representative samples six shallow wells irrigated fields and four adjacent non-irrigated (rain-fed agricultural lands) were selected. Dipmeter hand GPS (GARMIN 60) used for monitoring water table depth fixing lo...

In response to earlier findings or elevated levels of selenium in the Kendrick area, two detailed geochemical surveys were conducted in 1988 to stud y the distribution of selenium in soils (0-1 m depth), and new growth of associated big sagebrush (Artemisia tridentata Nutt.) and alfalfa (Medicago sativa L.). A survey of the native rangeland focused on specific geologic units as sources of selen...
