The many opportunities for mitigating atmospheric carbon emissions in developing countries include reforesting degraded lands, implementing sustainable agricultural practices on existing lands and slowing tropical deforestation. This analysis shows that over the next 10 years, 48 major tropical and subtropical developing countries have the potential to reduce the atmospheric carbon burden by ab...
Driven by global population and standard of living increases, humanity co-opts a growing share of the planet’s natural resources resulting in many well-known environmental trade-offs. In this study, we explored the impact of agriculture on a resource fundamental to life on Earth: terrestrial vegetation growth (net primary production; NPP). We demonstrate that agricultural conversion has reduced...
Right now it is not clear how other cost and benefit factors such as production economics, sustainability and carbon sequestration, and grain quality will be taken into account in the development of the criteria. Because of current water use impairments, and the expectation that the criteria, when developed and implemented, will add to the list of impairments, there is an immediate and continui...
Concentrations of thermotolerant coliform bacteria, presumptive E. coll, and presumptive fecal streptococci were determined from ditches, brooks, and natural ponds in six agricultural areas and 22 uninhabited pristine areas in southern Finland in the summer of 1987. For comparison, the same fecal indicators were enumerated from the effluents of three wastewater t eatment plants. The objective w...
Jiang, Yan, M.S.A.B.E., Purdue University, December 2013. Estimation of Watershed Nitrate Loads on Drained Agricultural Lands. Major Professor: Jane R. Frankenberger. Estimation of nutrient load is critical for many applications in water quality management; however, infrequent data monitoring and measurement error could raise considerable uncertainty in the load estimations. The objectives of t...
This study aimed to evaluate the effects of Hana’s dam (constructed in 1996) on land use and cover changes using Landsat satellite images. Three images over 35 years (taken in 1976, 1998, and 2011) were obtained and geometric, atmospheric and topographic corrections were applied. The dam’s affected area was selected based on the interpretation of satellite imagery and local expert knowledge. Ma...
In this study, we analyze the effect of property taxes on changes between agricultural, forestry, Conservation Reserve Program, and developed land uses in Louisiana. We estimate a random parameters logit model of land-use conversion from the National Resources Inventory plot data. Our results indicate that land-use changes are inelastic with respect to property taxes. Simulation shows that curr...
Extended abstract 1- Introduction Wind erosion as an “environmental threat” has caused serious problems in the world. Identifying and evaluating areas affected by wind erosion can be an important tool for managers and planners in the sustainable development of different areas. nowadays there are various methods in the world for zoning lands affected by wind erosion. One of the most important...
INTRODUCTION In many countries around the world “developers” take the best agricultural lands for housing, and urbanization spreads rapidly. As a result, the agricultural industries are pushed into less productive lands in which the climate is not the most suitable for crops. A very good example is found in Israel. The best agricultural area is along the Mediterranean coast where the citrus ind...
