"When nitrogen limited fields are targeted ... yield gains are predicted to double. When nitrogen and irrigation co-limitations are targeted ... yield ... tripled." Lots of potential to raise yields in Indian rice production with tried and tested technologies. www.nature.com/articles/s41...
Rice production in India is a foundation for global food security, but strategies for sustainable intensification are uncertain. By combining large-scale surveys with predictive modeling, the authors ...
"using biofuels to achieve 0.7 ± 0.3 Gt CO2-eq yr−1 mitigation would require new nitrogen inputs to croplands of 21–42 Tg N yr−1. " 1 Tg is 1 million tons. So that sounds like... a lot of nitrogen. www.nature.com/articles/s43...
Decarbonization strategies can perturb the nitrogen cycle through elevating nitrogen inputs to the environment, potentially driving increased eutrophication. This Review explores the potential synergi...
Global crop production is getting more water-efficient. This new paper finds that "nearly 80% of crops reduced global average unit [water footprints] as crop yields improved and cultivation centred around more productive areas" iopscience.iop.org/article/10.1...
Electrification reduces deforestation and fuelwood collection in this case study from Côte d’Ivoire: www.sciencedirect.com/science/arti...
This paper investigates the impact of electrification on household practices related to deforestation in Côte d’Ivoire, specifically focusing on the e…
Landless agriculture is possible but energy-intensive. While not an immediate solution to land-related problems, this could one day - with the right energy system - usher in opportunities for conservation that we can only dream about today. Review: bmcbiol.biomedcentral.com/articles/10....
The vast majority of the food we eat comes from land-based agriculture, but recent technological advances in agriculture and food technology offer the prospect of producing food using substantially le...
Ouch. Systematic review finds that of 561 degrowth studies, large majority are "opinions rather than analysis", very few use modelling, use ad-hoc and subjective policy advice and lack policy evaluation, and few studies adopt a system-wide perspective. Doesn't make them wrong - but need to step up.
In the last decade many publications have appeared on degrowth as a strategy to confront environmental and social problems. We undertake a systematic …
More evidence that cheaper fertilizer leads to reduced deforestation through land sparing: www.sciencedirect.com/science/arti...
This study explores the impact of fertilizer (urea) prices on local deforestation by exploiting the exogenous variation in the world price of urea inc…
