AI Article Synopsis

  • Changes in how land is used, like building more houses and businesses, greatly affect the environment around the Yellow River, which is a very important river for the area.
  • Researchers created a model to show different future land use possibilities for the Yellow River Basin from 1990 to 2020, helping to plan for 2030 while keeping the environment in mind.
  • The study found that building more construction sites is harming the land and nature, but protecting grasslands and woodlands can help the environment and keep things balanced in the future.

Article Abstract

Land use changes have profoundly influenced global environmental dynamics. The Yellow River (YR), as the world's fifth-longest river, significantly contributes to regional social and economic growth due to its extensive drainage area, making it a key global player. To ensure ecological stability and coordinate land use demand, modeling the future land allocation patterns of the Yellow River Basin (YRB) will assist in striking a balance between land use functions and the optimization of its spatial design, particularly in water and sand management. In this research, we used a multi-objective genetic algorithm (MOGA) with the PLUS model to simulate several different futures for the YRB's land use between 1990 and 2020 and predict its spatial pattern in 2030. An analysis of the spatiotemporal evolution of land use changes in the YRB indicated that construction land expansion is the primary driver of landscape pattern and structure changes and ecological degradation, with climate change also contributing to the expansion of the watershed area. On the other hand, the multi-scenario simulation, constrained by specific targets, revealed that economic development was mainly reflected in land expansion for construction. At the same time, grassland and woodland were essential pillars to support the region's ecological health, and increasing the development of unused land emerged as a potential pathway towards sustainable development in the region. This study could be used as a template for the long-term growth of other large river basins by elucidating the impacts of human activities on land use and rationalizing land resource allocation under various policy constraints.

Background: The aim of this study is to investigate the effect of soil water stability on maize (Zea mays L.) yield, water use, and its photosynthetic physiological mechanisms, and to innovate the relationship between maize and soil water, which currently only considers soil water content and neglects soil water stability.

Methods: An organized water experiment was conducted on maize.

Professor, Department of Civil Engineering, Toronto Metropolitan University, Toronto M5B 2K3, Ontario, Canada.

In recent years, the impact of transportation activities on carbon (CO) emissions has gained global attention. In China, the severity of CO emissions from transportation is a pressing issue, necessitating the development of effective emission reduction strategies. This study uses taxi GPS data from Xi'an, China, to explore the spatial patterns and influencing factors of CO2 emissions.

Anaerobic co-digestion is emerging as an option for wastewater biosolids management. Variations in treatment parameters can impact odour emissions and, in turn, odour nuisance reduces community acceptance and alternatives for beneficial reuse of biosolids via land application. This study assessed odour emissions from digested sludge and biosolids resulting from the anaerobic co-digestion of wastewater sludge with beverage rejects (beer and cola) and food wastes.

The transition between aquatic and terrestrial habitats leads to extreme structural changes in sensorial systems. Olfactory receptors (OR) are involved in the detection of odorant molecules both in water and on land. Therefore, ORs are affected by evolutionary habitat transitions experienced by organisms.

Bats provide important ecosystem services, particularly in agriculture, yet integrating bat management into conservation plans remains challenging. Some landscape features considerably influence bat presence, diversity, and ecosystem service provision. Understanding the relationship between landscape structure, composition, pest suppression, and ecosystem services is crucial.
