“…Local natural resources are depleted as a result, the ecological balance is disturbed, and infrastructure is overburdened. In the study of Yang et al (2021), an analysis of remote sensing data from six development periods and building data vectors (weighted average building height, building volume, and floor area ratio) was conducted, as well as field studies, using the Jinshitan tourist area in China's Liaodong Peninsula as an example (Pi et al, 2022). Between 1988 and 2016, the weighted average building height, volume, and floor area ratio all increased continuously, while the proportion of those employed in the non‐agricultural sector increased by 99.57%.…”

Comparing the per capita incomes of urban and rural households reveals a sizable income disparity in the latter, as well as an uneven distribution of income across China's regions. This article discusses and ranks the drivers that affect rural development. Among the most critical are farmer support factors, transportation infrastructure development, information and communication technology development, and rural entrepreneurship. The decline in the Engel coefficient, which reflects changes in welfare and income elasticity estimates of food demand, and income elasticity itself, indicates that food demand for Chinese farmers has become extremely inelastic. The ranking of China's regions in terms of per capita income growth shows that the intended policy of wealth equalisation of the country's population is being followed.The objective is to modernise agriculture and reduce regional disparities for China to achieve the status of a moderately developed country shortly, which will require state assistance. The emphasis is on farmer welfare, rural areas, and agriculture. In the face of massive population densities, regional disparities, and vast heterogeneous territory, the land consolidation practice is demonstrated in various regions as a platform and lever for rural life revitalisation. Rural tourism development is defined as a means of generating additional jobs and ensuring the long-term viability of villages.The rural elite's decisive role in leading the agricultural sector's restructuring is emphasised. Central and local governments can use the results to strengthen the legislative framework, develop plans and programmes, and identify rural development models.

Applying Wind Erosion and Air Dispersion Models to Characterize Dust Hazard to Highway Safety at Lordsburg Playa, New Mexico, USA

et al. 2022

Lordsburg Playa, a dry lakebed in the Chihuahuan Desert of southwestern New Mexico (USA), is crossed by Interstate Highway 10 (I-10). Dust from the playa threatens highway safety and has caused dozens of fatal accidents. Two numerical models—the U.S. Department of Agriculture’s Single-Event Wind Erosion Evaluation Program (SWEEP) and the American Meteorological Society and U.S. Environmental Protection Agency Regulatory Model (AERMOD)—were used to simulate and predict the generation and dispersion of windblown soil, dust, and PM10 from playa hotspots and estimate PM10 concentrations downwind. SWEEP simulates soil loss and particulate matter emissions from the playa surface, and AERMOD predicts the concentration of transported dust. The modeling was informed by field and laboratory data on Lordsburg Playa’s properties, soil and land use/land cover databases, and weather data from meteorological stations. The integrated models predicted that dust plumes originating on the playa—including a large, highly emissive area away from the highway and a smaller, less emissive site directly upwind of the interstate—can lead to hourly average PM10 concentrations of tens, to hundreds of thousands, of micrograms per cubic meter. Modeling results were consistent with observations from webcam photos and visibility records from the meteorological sites. Lordsburg Playa sediment contains metals, as will its dust, but human exposures will be short-term and infrequent. This study was the first to successfully combine the SWEEP wind erosion model and the AERMOD air dispersion model to evaluate PM10 dispersion by wind erosion in a playa environment. With this information, land managers will be able to understand the potential levels of dust and PM10 exposure along the highway, and better manage human health and safety during conditions of blowing dust and sand at Lordsburg Playa.
