Halfway There? The Land Sector’s Contribution to Closing the Emissions Gap

To mitigate or not to mitigate?

To mitigate or not to mitigate?

A new report by the Union of Concerned Scientists summarizes the current state of knowledgde on the potential for climate change mitigation in the agricultural, forestry and other land use sectors: Half or more of emissions reductions needed to keep global temperature rise under 2 degrees could come from land sectors of major emitting countries.

The total mitigation potential in the land sector world wide is up to 13 Gt CO2eq per year, of which only eight countries – Brazil, China, the Democratic Republic of the Congo, the European Union, India, Indonesia, Mexico, and the United States can contribute around 7 Gt Co2eq/year. This would be 76% of the emissions gap in 2020 and 44% in 2030.

An interesting aspect of such estimates of mitigation potentials is that they assume carbon prices of up to $100 per ton. At this, it is difficult to imagine that only emissions from the land use sector would be taxed from climate policies, Rather, such policies would also and primarily involve the energy sector. This by itself would already bring down emissions and reduce the demands for mitigation from the land use sector. Indeed, recent results from a comprehensive climate policy study suggest that with average carbon prices of at most $60 over the period to 2100 and the use of adequate technologies, the land use sector would have to contribute only about 1.1 GtCO2eq/year if a 2 degree target is to be attained.

So, the sector’s potential for greenhouse gas mitigation should be more than sufficient.


A new climate for farming

In a new web special A New Climate For Farming Nature Climate Change presents a collection of articles and opinion pieces that deal with the various aspects of agriculture and climate change:

Climate change fundamentally alters the way that farmers need to plan and manage their operations. This is necessary to avoid the worst impacts of climate change while reducing greenhouse gas emissions and meeting growing demand for food, fuel and fibre. This is a grand challenge for farmers and has the potential to touch the lives of everyone that uses farmed produce; in short, all of us. In this focus, Nature Climate Change presents a variety of original research and opinion pieces that highlight important themes in our understanding of the effects of climate change on agriculture, agriculture’s influence on the climate and our capacity to adapt to better face these challenges.

Modeling climate change and agriculture: a special issue of Agricultural Economics

AgEconAgMIPA highly interesting series of articles on economic foresight modeling in the area of agriculture and climate change has been published in the January 2014 special issue “Modeling climate change and agriculture” of Agricultural Economics.

The articles present analyses of the future consequences of climate change and global socio-economic development trends for agricultural production, food consumption, along with the potential impacts of alternative policy responses to these developments. All articles are outputs of the Agricultural Model Intercomparison and Improvement Project (AgMIP) and the Inter-Sectoral Impact Model Intercomparison Project (ISI-MIP), which brought together key global economic modeling groups in a cross-model scenario comparison exercise.

The articles are not only insightful with respect to the projections themselves, but also give a very good impression of the present global economic modeling landscape. It is also highly valuable that identical scenarios have been simulated with a large number of simulation models. This provides important evidence about the degree of uncertainty in the model projections and helps understanding root causes for differences in model results.
