Showing items 27523 through 27531 of 73561.Land cover changes around Lake Mutirikwi in 1984–2011 were mapped from Landsat images using traditional image classification methods including the maximum likelihood classifier algorithm. The possibility of mapping the coverage and abundance of surface floating aquatic weeds was also tested.
BACKGROUND: Dramatic disparities in a range of health outcomes persist in Alameda County, California.
Land degradation in terms of soil degradation is a major environmental issue posing threat to sustainable livelihood in the semi-arid region of Central Myanmar. However, the studies on soil degradation status and its impacts in this region are very scanty.
The spatio-temporal distribution of land cover provides fundamental data for global climate and environmental change research. In recent decades, five global land cover maps have been produced based on remote sensing data sources and methodologies.
Soils are a vital substrate for agricultural production, play a central role in regulating the global carbon budget, and are a valuable source of biodiversity. Yet estimates of the global area affected by soil and land degradation are continuing to increase.
Spate irrigation, a floodwater harvesting and management system, has for the past 70 centuries provided a livelihood for about 13 million resource-poor people in some 20 countries. Despite being the oldest, the system still remains the least studied and the least understood.
This paper develops and applies a new approach for analyzing the spatial aspects ofindividual adoption of a technology that produces a mixed public-private good. The technologyis an animal insecticide treatment called a “pouron” that individual households buy and apply totheir animals.
In this paper, we examine the effectof Section 1031 tax deferredpayment on Texas agricultural landprice. To analyze the effects, weestimate the market equilibriumprice function using the dynamicpanel model and Texas agriculturalland sales for 1965-2007.
