Showing results for: GHG impacts and mitigation
This paper finds that production of the top ten global crops has already been affected by climate change, with mixed impacts across both crop type and geographical area. Oil palm has seen a 13% decrease in yields relative to those that would have been seen under historical climate conditions, while soybean has seen a 4% increase.
In this research note, the US-based Open Philanthropy Project discusses whether animal welfare might be helped or hindered by climate-focused reductions in meat consumption. For example, the note points out that meat types with a relatively low carbon footprint (e.g. chicken) are often from smaller animals (compared to, say, cows) and thus require more animals to be farmed and killed.
This book, edited by Mirza Hasanuzzaman, Kamrun Nahar and Mohammad Amzad Hossain, provides a comprehensive overview of the response of wheat cultivation to changing environmental conditions, including extreme temperatures, drought and ultra-violet radiation.
This working paper from the UK-based policy research organisation International Institute for Environment and Development explores the costs and benefits of different scenarios for future governance of high seas fisheries (i.e. those in international waters) under a changing climate.
This modelling paper finds that strategies to mitigate climate change could put an additional 160 million people at risk of hunger by 2050, if they are not designed carefully. However, these trade-offs could be avoided at a cost of around 0.2% of GDP in 2050.
New Zealand has introduced a new bill that aims to bring emissions of long-lived greenhouse gases to net zero by 2050. A separate target has been set for methane emissions from agriculture, with planned cuts of 10% by 2030 and 24% to 47% by 2050.
The Fate of Food: What We'll Eat in a Bigger, Hotter, Smarter World, by Amanda Little, examines the innovations that are changing food production.
Extreme climate events such as droughts and heat waves are better predictors of yield anomalies than indicators of climate averages in maize, rice and soybeans, according to this paper. Irrigation can mitigate the negative yield impacts of frequent warm days.
The UK Parliament has endorsed a motion to declare a climate and environment emergency, in response to the 2019 Extinction Rebellion protests and calls from the Labour opposition. The motion, which is not legally binding, follows declarations of a climate emergency by the Welsh Government, Nicola Sturgeon, First Minister of Scotland, and several cities across the UK.
This report by United Nations Environment reviews the current state of the environment and policy responses, with a particular focus on the links between planetary health and human health. It covers the impacts of the food system and risks to food security caused by environmental degradation.
This report from the UK’s Committee on Climate Change sets out how the UK can reach net zero emissions by 2050 using existing technologies. It notes that current policies do not do enough to meet existing climate targets, and calls for “clear, stable and well-designed policies” to be introduced across the economy without delay. If replicated across the world, the plan would give a greater than 50% chance of limiting warming to 1.5°C.
Schools strike climate activist Greta Thunberg, along with several scientists, authors and campaigners, has called for “natural climate solutions” to tackle climate change and biodiversity loss simultaneously.
This report from the Japanese Institute for Global Environmental Strategies shows how lifestyles would have to change in industrialised countries and some industrialising countries in order to meet climate change targets.
This paper uses climate models to estimate that average precipitation across many crop production areas will change by more than natural variability throughout the 21st century. Changes are seen even if emissions are relatively low, but meeting the Paris climate goals could reduce the extent of cropland that is affected.
Extreme weather events such as frosts, heavy rains and droughts are the main drivers of lower olive yields in Italy, according to Professor Riccardo Valentini of the Euro-Mediterranean Centre for Climate Change. Italy has experienced a 57% drop in olive oil production in 2018.
This book by Mike Berners-Lee aims to provide a big-picture overview of how to solve the many environmental issues the world is facing now, including both systemic and personal paths of action. It is aimed at a wide audience including both policymakers and the general public. Chapter 2 is about food.
This paper retrospectively models the impacts of ocean warming on the productivity of 235 fish populations around the world representing around one third of reported global catch. It uses a temperature-dependent population model to estimate that the overall maximum sustainable yield of the fish populations dropped by 4.1% between 1930 and 2010.
