In this study, a field experiment was conducted during 2017–2020 in 3 farmland areas, each with different altitudes and climate conditions, in northern Xinjiang, China, to analyse the plastic residue pollution and greenhouse gas emissions. The effects of plastic film mulching (PFM) versus no mulching (NM) methods in drip-irrigated maize production were investigated, regarding maize yield, economic returns, and greenhouse gas (GHG) emissions. Different maize hybrids with three different maturation times and two planting densities were chosen to further investigate how those differences more specifically affect maize yield, economic returns, and greenhouse gas (GHG) emissions under each mulching method. By matching the required accumulated temperatures of various maize varieties to environmental accumulated temperatures, along with filmless and higher density planting and modern irrigation and fertilisation practices, yields increased, and at the same time, residual plastic film pollution and carbon emissions were found to decrease. The study highlights that advancements in agronomic management are an important step towards reducing pollution and achieving carbon peak and carbon neutrality goals.
The Ocean Plastics Charter aims to bring together leading countries, sub-national governments, businesses, and civil society organisations to commit to a more resource-efficient and sustainable approach to keep plastics in the economy and out of the environment. With this charter, it aims to transition to a more sustainable and resource-efficient method of managing plastics. Through[…]
These regulations are intended to promote sustainable development, food security, and the sustainable management of fishing activities in Palau’s waters. They also intend to create economic returns, employment generation, and export earnings from the sustainable harvesting of tuna and tuna-like species by encouraging the development of domestic fishing industries and a local tuna market. These[…]
This subchapter E of Title 40 of the Code of Federal Regulations outlines the pesticide programs, including registration and classification procedures, policies, special review procedures, standards, labelling requirements, packaging requirements, data requirements, and good laboratory practice standards. It also covers state registration of pesticide products, rules of practice governing hearings under the federal Insecticide, Fungicide,[…]
The Plastics Roadmap aims to decrease littering and other environmental harm brought on by plastics, prevent needless use, enhance plastic recycling, and replace traditional polymers derived from fossil fuels combined with various substances and liquids. To guarantee more focus on sustainable product development, reuse, product recyclability, and the growing usage of recovered plastics, these objectives[…]
The regulations aim to enhance aquaculture pollution prevention and control, protect aquatic ecosystems, ensure product quality and safety, and promote sustainable development. They consist of 24 articles divided into four sections: general provisions, delimitation of prohibited areas, pollution prevention and control, and environmental monitoring and supervision of fishery waters.
