Our modern crops need some help in the immunity department.

theconversation – When you pick up the perfect apple in the supermarket it’s easy to forget that plants get sick just like we do. A more realistic view might come from a walk outside during summer: try to find a leaf without a speck, spot or blemish. Tough, huh? Those are the signs of a microscopic battle waged every day in and on plants.

Plants get sick too. Carsten Niehaus

Just like us, plants are covered in microbes. And just like us, plants have evolved an immune system to protect against the dangerous ones. But our current agricultural system works against plants’ natural immune defenses, by limiting the tools plants have to fight back and restricting evolution of new tools.

MOOC: Powering Agriculture—Sustainable Energy for Food

~ Đào Thu Hằng ~ Bình luận về bài viết này

poweringag.org – We are happy to announce that the global initiative “Powering Agriculture: An Energy Grand Challenge for Development” (PAEGC) is launching a free Massive Open Online Course (MOOC) in cooperation with TH Köln – University of Applied Sciences. The 8-week course, which will run from Feb. 1 – Mar. 27, 2016, introduces challenges and solutions for sustainable energy use in the agriculture and food industry.

Background

Around one third of the energy used worldwide goes into the production and processing of food from field to table. Given the current energy system mix, the agrifood industry sector is however heavily dependent on fossil fuel inputs for production, transport, processing and distribution, and contributes significantly to greenhouse gas emissions. With a continuously growing world population the need for food and for energy to produce it is increasing. At the same time millions of farmers and processors in developing countries and emerging economies lack access to clean energy technologies for irrigation, drying, cooling, storage and other processes.

How can these needs be met sustainably?

We have to produce more food with less energy, make energy use more efficient, and introduce and upscale more clean energy technologies.

About the Course

This MOOC will introduce participants to the Energy-Agriculture Nexus and introduces approaches for sustainably providing energy throughout all stages of agricultural value chains. Challenges but also solutions will be analyzed, concrete technologies will be examined focusing on their utility to promote access to clean energy. Participants will further be familiarized with relevant external influences such as market conditions, politics, and financing schemes of “powering agricultural” projects. Learning materials, developed by well-known experts, will be available as texts as well as videos on a week-by-week basis and are accompanied by assignments that will require the application of the newly learned skills.
