A stable farmland tenure can optimize farmers’ allocation of production factors and then determine the income level and structure of farmers. In recent years, the reform of China’s farmland tenure system had been making efforts to strengthen the stability of farmland tenures. Will the farmland tenure security restrict agricultural development? Based on the data of the 2018 China Labor Dynamics Survey (CLDS), this paper empirically analyzes the impact of farmland tenure stability on rural household income and its mechanism.
Malaysia’s Forest Pledges and The Bornean State of Sarawak: A Policy Perspective
Malaysia deforested 6.3 million hectares since independence; 91% of which occurred before Malaysia pledged, at the Earth Summit in 1992, to maintain a minimum 50% of its terrestrial area under forest cover. However, under economic and population pressure, Sarawak—the largest contributing state to the country’s current forest cover of 54.8%—shows continuing deforestation even after 1992.
In Pursuit of Local Solutions for Climate Resilience: Sensing Microspatial Inequities in Heat and Air Pollution within Urban Neighborhoods in Boston, MA
Environmental hazards vary locally and even street to street resulting in microspatial inequities, necessitating climate resilience solutions that respond to specific hyperlocal conditions. This study uses remote sensing data to estimate two environmental hazards that are particularly relevant to community health: land surface temperature (LST; from LandSat) and air pollution (AP; from motor vehicle volume via cell phone records).
Reducing Octane Number Loss in Gasoline Refining Process by Using the Improved Sparrow Search Algorithm
Gasoline is the primary fuel used in small cars, and the exhaust emissions from gasoline combustion have a significant impact on the atmosphere. Efforts to clean up gasoline have therefore focused primarily on reducing the olefin and sulfur content of gasoline, while maintaining as much of the octane content as possible. With the aim of minimizing the loss of octane, this study investigated various machine learning algorithms to identify the best self-fitness function. An improved octane loss optimization model was developed, and the best octane loss calculation algorithm was identified.
Effects of the Most Appropriate Proportion of Phytohormones on Tree-Ring Growth in Clones of Hybrid Larch
The increase in the atmospheric carbon dioxide concentration promotes its accumulation in trees by regulating the synthesis and transportation genes for endogenous hormones, such as IAA and GA, which are key factors in regulating various life activities, including growth rings.
