The primary aims of the study are:(1) to determine SQI values of the micro-basin in terms of land degradation and desertification.Moreover, the best-worst method(BWM) was used to determine the weighting score for each parameter;(2) to produce the soils' spatial distribution by utilizing different geostatistical models and GIS(geographic information system) techniques;and(3) to validate the obtained SQI values with biomass reflectance values. Therefore, the relationship of RE-OSAVI(red-edge optimized soil-adjusted vegetation index) and NDVI(normalized difference vegetation index) generated from Sentinel-2A satellite images at different time series with soil quality was examined. Results showed that SQI values were high in the areas that had almost a flat and slight slope. Moreover, the areas with high clay content and thick soil depth did not have salinity problems, and were generally distributed in the middle parts of the basin. However, the areas with a high slope, poor vegetation, high sand content, and low water holding capacity had low SQI values.Furthermore, a statistically high positive correlation of RE-OSAVI and NDVI indices with soil quality was found, and NDVI had the highest correlative value for June(R~2=0.802) compared with RE-OSAVI.展开更多

A list of 16 quality and safety attributes of milk products based on previous studies was compiled and used in this study. The balanced incomplete block design technique was used to build the questionnaire administered to respondents in the data collection. The multinomial mixed logit was employed to analyze the data. Results suggest that nutritive value, shelf life, availability, purity and safety are the most important attributes of milk product; while origin, fat content, food miles, packaging and handling convenience are the least importance attributes of milk products to consumers The study concludes that demand for dairy products can be significantly stimulated in the study area when these most important attributes have been considered by producers, processors and marketers.展开更多
