Depopulation of rural landscapes exacerbates fire activity in the western Amazon by Uriarte, Maria, DeFries, Ruth S., Fernandes, Kátia, Gutiérrez Vélez, Victor Hugo, Baethgen, Walter E., Padoch, Christine, Pinedo Vasquez, Miguel

“…Destructive fires in Amazonia have occurred in the past decade, leading to forest degradation, carbon emissions, impaired air quality, and property damage. Here, we couple climate, geospatial, and province-level census data, with farmer surveys to examine the climatic, demographic, and land use factors associated with fire frequency in the Peruvian Amazon from 2000 to 2010. …”

Agroecological impacts of crop residue burning: a qualitative systematic review of direct and inferred evidence by Parambil-Peedika, Ashiq, Laing, Alison M., Gathala, Mahesh Kumar, Adeeth AG Cariappa, Krishna, Vijesh V.

“…Findings from broader air pollution studies, used here as secondary evidence, offer valuable inferential insights into the potential ecological impacts of crop residue burning on birds and arthropods, mediated through changes in air quality. Despite these documented consequences, agrobiodiversity considerations are largely absent from policy discussions on residue management. …”

Greenhouse gas emissions from piggery and biogas digesters in the Red River Delta of Vietnam by Dung Van Pham, Hoan Duong Cong, Arango, Jacobo, Nghia Tran Dai, Kien Nguyen Tri, Arévalo, Ashly, Douxchamps, Sabine

“…The findings show that CO2, CH4 and N2O emission rates from pig manure are at least twice as much what is allowed under the Vietnam national technical regulation on ambient air quality. However, the GHGs emission rate does not significantly differ between smallholder and industrial-scale farms in the four surveyed provinces. …”
