TL;DR: In this paper, the authors summarized the current understanding and concerns of plastics pollution (microplastics or nanoplastics) on natural ecosystems and provided a background assessment on the adverse effects of plastic pollution on terrestrial and aquatic ecosystems; interlink the management of plastics with sustainable development goals; address the policy initiatives under transdisciplinary approaches through life cycle assessment, circular economy, and sustainability; identify the knowledge gaps; and provide current policy recommendations.

TL;DR: In this article, a comprehensive review on physical processes involved in microplastics transport in riverine ecosystems is presented, highlighting how appropriately empirical transport models explain vertical and horizontal distribution of microplastic.

TL;DR: In this article, the impacts of dry spells in soybean and identified better management of water resources under varying water-scarce conditions were examined using field experiments and modeling studies, and the results showed that plants subjected to water stress during flowering and vegetative growth stages had significantly lower yields and total dry matter.

TL;DR: In this article, a survey was developed to understand smallholder farmer perceptions regarding the anticipated impacts of the COVID-19 pandemic on their agriculture practices and social well-being.

TL;DR: In this paper, the impact of cropping systems and water management practices on yield of different crops were simulated using the Decision Support System for Agrotechnology Transfer-Cropping System Model.
