In this study, a land use/land cover change analysis method was developed to examine patterns of land use/land cover conversions of cropland to urban uses and conversions of rangeland to cropland uses in the United States (US) Midwest region. We used the US 2001 and 2006 National Land Cover Datasets (NLCD) for our spatial analyses of these conversion trends. Our analysis showed that the eastern...

CARMA (CAse-based Range Management Adviser) is a system that integrates case-based reasoning with model-based reasoning for rangeland pest management. CARMA’s predictions of rangeland forage loss by grasshoppers were compared to predictions by 15 expert entomologists using either global or case-specific adaptation weights. Under both conditions, CARMA’s predictions were more accurate than CARMA...

abiotic factors, as topographic and physicochemical properties of soil, are the most important effective factor on vegetation in rangeland ecosystems which have the most important performances to forming and succession of plant vegetation. ecologic management of rangelands can be desired by better understanding of these effective factors. then, rangeland of javaherdeh (ramsar) in the northern a...

Soil erosion is one of the most critical threats to cultivated land. Yet little information available in Sub-Saharan Africa, especially on relative contributions various forms erosion. Therefore, this study’s objective was quantify soil loss by sheet and linear The study carried out sloping land rangeland Potshini catchment KwaZulu-Natal, South with an annual average rainfall 766 mm. computed u...

Spectral matching and linear mixture modeling techgeological mapping because it allowed identification and niques have been applied to synthetic imagery and mapping of the relatively pure regions of all the surficial AVIRIS SWIR imagery of a semiarid rangeland in order materials that exert an influence on the spectral response. to determine their effectiveness as mapping tools, the The maps of ...

Rain-index insurance is strongly advocated in many parts of the developing world to help farmers to cope with climatic risk that prevail in (semi-)arid rangelands due to low and highly uncertain rainfall. We present a modeling analysis of how the availability of rain-index insurance affects the sustainability of rangeland management. We show that a rain-index insurance with frequent payoffs, i....
