Reassessing the warming impact of methane emissions from Irish livestock using GWP*: historical trends and sustainable futures

Irish Journal of Agricultural and Food Research
Methane from livestock production contributes significantly to Ireland’s greenhouse gas emissions. Methane emissions are generally expressed as carbon dioxide equivalents (CO2e) using the global warming potential (GWP) metric, but this conversion may ...

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

PLANTS, PEOPLE, PLANET, EarlyView.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...

Identifying opportunities for nature-based solutions with geospatialized life cycle assessments and fine-scale socioecological data

Environmental Research Letters
As we increasingly understand the impact that land management intensification has on local and global climate, the call for nature-based solutions (NbS) in agroecosystems has expanded. Moreover, the pressing need to determine when and where NbS should be
