The Pacific Coast Federation of Fishermen's Associations has taken legal action against 30 fossil fuel companies, arguing that the crab fishing industry is being harmed by climate change. Algal blooms, made more likely by warming ocean waters, have cut short crab fishing seasons.

Non-profit organisation Ceres has produced an overview of resources (standards, methodologies, tools, and calculators) for assessing greenhouse gas emissions from agricultural production and agriculturally-driven land use change.

The Centre for Biological Diversity has calculated the emissions produced by the food offered at the ongoing COP24 climate conference, arguing that the many meat-based options mean the menu has an “unnecessarily high carbon foodprint”.

The US Global Change Research Programme has published the second volume of its Fourth National Climate Assessment, which examines the human welfare, societal, and environmental impacts of climate change and variability across many sectors, including agriculture.

In this report, the InterAcademy Partnership expresses concern over the current state of global food systems and nutrition, and also identifies science-based initiatives that could contribute to solutions.

This report by the RISE Foundation (Rural Investment Support for Europe), co-authored by FCRN member Elisabet Nadeu, outlines the environmental and health impacts of livestock production and consumption in the EU. The report suggests that there is a “safe operating space” for livestock production, defined at the lower bound by the provision of nutrition to humans and the maintenance of permanent pasture habitats, and defined at the upper boundary by climate impacts and nitrogen and phosphorus emissions.

A recording of the launch of the report “Negative Emissions Technologies and Reliable Sequestration: A Research Agenda” can be viewed here, hosted by the National Academies of Sciences, Engineering, and Medicine. The video is around one hour long and includes an overview of the report’s findings and a question-and-answer session.

The report “Missing pathways to 1.5°C: The role of the land sector in ambitious climate action”, by the Climate Land Ambition and Rights Alliance, assesses greenhouse gas mitigation pathways that use “low-risk” land-based solutions that protect natural ecosystems and respect human rights. The report aims to provide an alternative to the IPCC’s mitigation pathways, many of which rely on mitigation approaches such as bioenergy with carbon capture and storage (BECCS).

Losses of wheat, rice and maize to insects could increase by 10 to 25% per degree Celsius of climate warming, according to this paper. This is due to two main factors: insects have faster metabolisms at higher temperatures and therefore need to eat more; and insect population growth rates will also change with temperature.

US-based consulting firm Breakthrough Strategies & Solutions has created a list of recent papers, reports, conferences, media items, jobs and other resources on the topics of soil health and soil carbon sequestration.

The Intergovernmental Panel on Climate Change (IPCC) has released a special report on keeping climate change to 1.5°C. The report says, “Limiting global warming to 1.5°C would require rapid, far-reaching and unprecedented changes in all aspects of society.”

A combination of measures including a shift towards plant-based diets, halving food waste and technological changes in agriculture (such as more efficient fertiliser application, feed additives and changes in irrigation) could significantly reduce the food system’s environmental impacts relative to 2050 projections and potentially even reduce impacts below today’s levels, according to a new paper.

The cost-effectiveness of different methods of cutting agricultural greenhouse gas emissions is often calculated using marginal abatement cost curves (MACCs). FCRN member Dominic Moran of the University of Edinburgh has quantified the uncertainties in calculating MACCs for Scottish agricultural mitigation options, including improving land drainage, improving the timing of nitrogen application, and using controlled release fertilisers. The paper suggests that policymakers may wish to exclude options that have a high uncertainty, as they may not always be as cost-effective as the MACC suggests.

This book, by Leonard Rusinamhodzi, describes the concept of ecosystems services, shows how to identify and quantify ecosystems services in the context of sustainable food systems, and examines the challenges of maintaining ecosystems services in the face of climate change.

New Zealand’s Parliamentary Commissioner for the Environment has released a report exploring how much and over what timescale the climate is affected by methane emissions from livestock. It focused on two questions. First,if methane emissions from livestock were held at current levels or followed business-as-usual trajectories, what would their contribution to future warming be? Second, what reduction in methane emissions from livestock would be needed so that they cause no additional contribution to warming?

A recent paper uses data from volcanic eruptions to estimate the effects that geoengineering with sulphate aerosols would have on agricultural production. It concludes that the damage that geoengineering would do to maize, soy, rice and wheat outputs (because of reduction in sunlight reaching the crops) would have roughly the same magnitude as the benefits of the cooling it would provide.

A carbon tax applied across the whole economy, including agriculture, could put more people at risk of hunger (in terms of dietary energy availability) than climate change itself, according to a recent paper.
