One of the world’s major issues is climate change, which has a significant impact on ecosystems, human beings, agricultural productivity, water resources, and environmental management. The General Circulation Models (GCMs), specially the recently released (coupled model intercomparison project six) CMIP6 are very indispensable to understand and support decision makers to identify adaptation strategies in response to future climate change in a basin. However, proper selection of skillful GCMs and future climate assessment is a prior task to climate impact studies.

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.

Coastal lands are often affected by salinization, which leads to a deterioration of soil structure and a decrease in land productivity. As a widely used soil amendment, biochar has been proven to improve poor soil properties and promote crop growth and N adsorption and utilization. However, the effects of biochar on soil fertility, N use efficiency (NUE) and balance in coastal salt-affected soil have rarely been reported.

Vegetable extraction has been considered a new paradigm of adequate development for the Amazon Region by ecological movements, international organizations, and foreign governments. This study evaluates whether the supply of extractive products transformed into economic value can ensure the livelihood of families and prevent deforestation. The study was conducted at the extractive reserves Alto Juruá, Rio Ouro Preto, and Rio Cajari during two periods: January to March 2017 and January to March 2019. A total of 384 interviews were conducted—234 in 2017 and 150 in 2019.

Since the dawn of Brazilian trade, extensive cattle farming has predominated. Brazil’s extensive pasture-based system uses pasture plants adapted to climate and soil conditions with limited use of purchased inputs. However, new technologies such as integrated crop and livestock systems have recently been adopted, with government support and public policies that are intended to encourage increased agricultural production in Brazil.

Buckwheat is an important coarse grain often grown in China’s marginal and dry mountainous areas; however, few empirical studies have quantified the factors that increase land productivity and encourage buckwheat farmers’ market participation.

The Mekong Delta region has been seriously affected by climate change, with increasing temperatures, sea-level rise, and salinization strongly impacting agricultural activities of the region. Recent studies have shown that groundwater exploitation also contributes significantly to land subsidence throughout the delta. Thus, combating climate change now makes it necessary to design strategies and policies for adapting to and mitigating climate change and subsidence, not only at the individual level (mainly farmers), but also at the institutional level (province and region).

COVID-19 caused a major shift in consumer behavior online at companies that focused on offering products to a traditional and more diverse (LGBTTTQI+) market. For this reason, an online survey was carried out through the digital platforms Facebook and LinkedIn in the last months of the pandemic (COVID-19) to determine how interpersonal influences and electronic word of mouth (eWOM) affect the intention to buy back online products and services, even after the pandemic.

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.

Plastic bag pollution in the marine environment is an urgent issue that has negatively impacted the sustainability of marine biodiversity. Studying effective ways to design advocacy messages that can promote individuals’ intentions to reduce, reuse, and recycle plastic bags in order to mitigate plastic bag pollution in the effort to help restore marine biodiversity is necessary. Utilizing emotional appeal messages, such as messages that are designed to elicit audiences’ feelings of empathy, can promote a variety of pro-environmental behaviors.

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).

Based on a case study in each country, this study documents the views of Mozambican and Tanzanian smallholders regarding Chinese agricultural investments and the extent to which investors abide by their legitimate land tenure rights as defined by the Voluntary Guidelines for the Responsible Governance of Tenure of Land, Forests and Fisheries in the Context of National Food Security (VGGTs). The VGGTs offer guidelines to government on how to protect the land tenure of rural communities when land is being acquired for large-scale land investments.
