Standard Precipitation Index (SPI) analysis in Karoon 3 Watershed under climate change
The aim of this study is to investigate climate change impact on Karoon3 basin in future periods. For this purpose, the simulated precipitation of 10 AOGCM models, including BCM2.0, CGCM3T63, CNRMCM3, CSIROMK3.0, GFDLCM2.0, GISS-ER, HADCM3, INMCM3.0, IPSLCM4, MIROC3.2 MEDRES was used to simulate drought index. Monthly precipitation was calculated by inverse distance weighted method. Standard Pr...
متن کاملSoil quality improvement under an ecologically based farming system in northwest Missouri
Ecologically based farming conserves and improves the soil resource and protects environmental quality by using organic or natural resources without the application of synthetic chemicals. Soil quality assessment indicates the ability of management systems to optimize soil productivity and to maintain its structural and biological integrity. Our objective was to evaluate the effect of ecologica...
متن کاملEnhanced top soil carbon stocks under organic farming.
It has been suggested that conversion to organic farming contributes to soil carbon sequestration, but until now a comprehensive quantitative assessment has been lacking. Therefore, datasets from 74 studies from pairwise comparisons of organic vs. nonorganic farming systems were subjected to metaanalysis to identify differences in soil organic carbon (SOC). We found significant differences and ...
متن کاملDeveloping a soil quality index to compare soil fitness for agricultural use under different managements in the Mediterranean environment
Due to increasing land-use pressures, soil-quality assessment is in growing demand, thus a standard set of procedures to assign a soil quality index (SQI) would be beneficial. In this study, the effectiveness of different managements in upholding soil quality (for crop productivity) was compared using soil quality indicators incorporated systematically to determine a SQI. The managements includ...
متن کاملValuing watershed quality improvements using conjoint analysis
This paper reports on a study of valuation of multiple stream quality improvements in an acid-mine degraded watershed in Western Pennsylvania. A technique extensively used in marketing research, conjoint (CJ) analysis, is used in conjunction with a random utility model (RUM) to establish shadow valuations for various combinations of stream quality improvements in two streams. The technique show...
