To better understand the impacts of infrastructure investment on economic growth and, we used Cobb-Douglas production function model to develop the stock of public infrastructure capital into the economic growth model. It applies spatial panel data model effect analysis to statistical data of the Yangtze River Economic Zone with 131 cities from 2003 to 2016 and investigates the relationship between different types of public infrastructure capital stock and regional economic growth in different periods.
Reversing Channels and Unsettling Binaries: Rethinking Migration and Agrarian Change under Expanded Border and Immigration Enforcement
Unauthorized migration under global regimes of border and immigration enforcement has become more risky and costly than ever. Despite the increasing challenges of reaching, remaining in, and remitting from destination countries, scholarship exploring the implications of migration for agricultural and environmental change in migrant-sending regions has largely overlooked the prevalent experiences and consequences of “failed” migration.
Effect of Organic Fertilizer on Soil Bacteria in Maize Fields
Soil microorganisms play an important role in agricultural ecosystems, but their response to organic fertilizer application has not been thoroughly elucidated. Thus, high-throughput sequencing was used to investigate the responses of soil bacterial to organic fertilizer amendment (composted from pig manure) in the field during the entire growth cycle of maize plants.
Evolutionary Overview and Prediction of Themes in the Field of Land Degradation
Land degradation has become one of the major global environmental problems threatening human well-being. Whether degraded land can be restored has a profound effect on the achievement of the 2030 UN Sustainable Development Goals. Therefore, the ways by which to identify the current research status and potential research topics in the massive scientific literature data in the field of land degradation is a crucial issue for scientific research institutions in various countries.
Environmental Threats over Amazonian Indigenous Lands
This study investigates the main threats related to environmental degradation that affect Amazonian Indigenous Lands (ILs). Through a cluster analysis, we group ILs according to the set of common environmental threats that occur within and outside their limits. The results show that most of the 383 ILs are affected internally by a combination of different environmental threats, namely: deforestation, forest degradation, fires, mining, croplands, pastures, and roads.
