Microplastics (MPs) emerged as a critical global pollutant, yet their effects on soil greenhouse gas (GHG) emissions remain uncertain. This meta-analysis evaluates the effects of MPs exposure on GHG emissions and identifies key influencing factors. Regardless of any influencing factors, MPs exposure decreased NO emissions by 28.

Gas sensors are essential measurement devices that have found extensive applications across various fields, including industry, agriculture, ecological and environmental monitoring, military operations, and biomedical research. Numerous sensing methods based on a diverse range of principles-including optics, electrochemistry, and semiconductors-have been used in the development and manufacture of gas sensing technologies. However, the measurement of certain gases remains challenging when using current sensing techniques and sensors; this is particularly true for the gases that are present in solid media.

Global fluvial ecosystems are important sources of greenhouse gases (CO, CH and NO) to the atmosphere, but their estimates are plagued by uncertainties due to unaccounted spatio-temporal variabilities in the fluxes. In this study, we tested the potential of modeling these variabilities using several machine learning models (ML) and three different input datasets (remotely sensed vegetation indices, in-situ water quality, and a combination of both) from 20 headwater catchments in Germany that differ in catchment land use and stream size. We also upscaled fluvial GHG fluxes for Germany using the best ML model and explored the role of catchment land use on the GHG spatial-temporal trends.

Peatlands cover 3 % of the Danish land area, but drainage of these areas contributes to approximately 25 % of the total agricultural greenhouse gas (GHG) emissions. Paludiculture, defined as agriculture on wet or rewetted peatlands, has been proposed as a strategy to mitigate GHG emissions while keeping up production. However, little is known about the net GHG effects during establishment and how it is influenced by soil biogeochemical conditions.

Dairy farms in developing countries are key to fighting hunger and poverty. However, their environmental and economic impact in the tropical region of Peru has been scarcely studied. The CLEANED tool, developed by the Alliance of Bioversity International and the International Center for Tropical Agriculture, allows us to assess the productive situation and the environmental and economic impact of different dairy systems.
