Energy Choice

The relationship between increasing income of rural households and energy choice is explored. Previous studies have been equivocal because they ignored the consideration of out-migration, which is a distinctive characteristic of present China . This study provides additional insight by considering income structure and energy structure of rural households in western China. The research was conducted in Zhouzhi County in the jurisdiction of Xi’an city, Shaanxi Province, China. Through questionnaire survey, 1074 rural households’ detailed information about their livelihoods were obtained. After descriptive statistics analysis and econometrics model analysis, we provide evidence that migration income plays a important role when rural households choosing modern energy such as electricity or gas, which shows higher income housholds like to choose cleaner but expensive energy. We also find out-migration can reduce family firewood consumption, transforming the use of firewood to other cleaner forms of energy, which can keep the ecological environment sustainable development.

Tamarix taklamakanensis is an endangered shrub endemic to the Tarim Basin and adjacent Kumtag Desert in north-western China. Here, we used two chloroplast DNA sequences, namely, psbA-trnH and trnS-trnG, to examine the genetic diversity patterns of this species across its entire covered range. A total of nineteen haplotypes were detected. The total gene diversity within the species is high. Genetic variation mainly occurred among populations, SAMOVA groups, and geographic regions. The test for isolation-by-distance showed a significant correlation between genetic and geographical distances, and the genetic landscape shape analysis showed a significant genetic divergence between the Tarim Basin and Kumtag Desert. T. taklamakanensis likely had a potential geographic range during the Last Glacial Maximum period that was much smaller than the present range predicted by ecological niche modelling. The cold and dry climate during the glacial periods of the Quaternary might be a driver of the genetic isolation and divergence detected within T. taklamakanensis, and climatic oscillations might account for the habitat fragmentation of the species. Within the inner of the basin, populations have a higher level of genetic diversity and harbor most of this genetic diversity, thus a nature reserves should be set up in this area for the in situ conservation. In addition, five genetically distinct groups within T. taklamakanensis should be treated as different management units (MUs) when implementing conservation activities.

Abstract The initial occurrence of desert landscape or eolian sand dunes is thought to have occurred long before the Pleistocene, and desertification was subsequently enhanced under cold, dusty glacial conditions. However, when and how the desert landscape persisted during both glacial and interglacial periods, defined as “permanent” desert here, remain elusive. Here, we present carbonate carbon isotope and grain-size records from the Tarim Basin, western China, revealing a detailed desertification history for the Taklimakan Desert. Our records demonstrate that after desiccation of episodic lakes at ca. 4.9 Ma, alternations of eolian sand dunes and fluvial and playa-like conditions persisted for a long period until 0.7 Ma in the Tarim Basin. The onset of permanent desert landscape around 0.7–0.5 Ma occurred concurrently with the climatic reorganization across the mid-Pleistocene transition. The occurrence of mountain glaciers on the Tibetan Plateau and atmospheric circulation changes may have controlled the formation and extreme aridification of the permanent desert in inland Asia since the mid-Pleistocene transition.
