Relationships between vegetation indices and surface reflectance: Implications for detecting and monitoring sandification in arid regions

open access: yesEcological Indicators
Terminal lakes in arid regions are increasingly vulnerable to sandification under water scarcity and climate stress. Taking the Qingtu Lake region in China’s Shiyang River Basin as a case study, we evaluated different vegetation indices and surface ...

POVERTY, LAND DEGRADATION AND CLIMATIC UNCERTAINTY [PDF]

open access: yesOxford Economic Papers, 1997
This paper studies farmers who operate in a risky environment at a minimum level of subsistence. In particular we investigate how poverty influences the soil conservation decision in the absence of formal insurance markets. It is shown that the consequences for the optimal soil conservation decision from poverty differ across the three agricultural ...
