Eco-efficiency and climate change
Last week I presented an internal seminar in CIAT together with DAPA colleague Patrick Lavelle (also from IRD). The first part of the presentation demonstrated the five reasons why the world needs an eco-efficient agriculture, then Patrick followed up by showing how we can establish eco-efficient landscapes to enable change on the ground using an example in the Amazon. The full presentation can be found here on slideshare, as always.
But I would like to highlight two of the five reasons for establishing eco-efficient agriculture on this blog post:
One is that our analyses of impacts of climate change on biodiversity show how species need to move around to survive. The implications are that we either need to double the coverage of protected areas (unlikely given other demands for land), or we need to ensure that we have productive landscapes that provide food for an increasing population that also conserve biodiversity and enable the movement of species through them. In short, we need multi-functional landscapes – food provision and ecosystem service maintenance.
The second is entirely based on a graph I spotted in a presentation made by Carlos Cano in the ICESI university recently. Ever since seeing it I was fascinated. It shows the rather shocking growth in CO2 emissions in China and Colombia, compared to the world, the USA and Europe. Whilst all the spotlight is on developed nations to make serious emissions cuts, it is developing countries that are on alarming development pathways with respect to greenhouse gas emissions. It’s inevitable that the climate change mitigation spotlight will eventually turn to emerging economies, and eco-efficiency in agriculture is a key concept for ensuring that the development pathways are climate-friendly. Check out the graph for yourselves.
