There is no doubt that humanity needs an alternative agricultural development paradigm, one that encourages more ecologically sound, biodiverse, resilient, sustainable, and socially just forms of agriculture. The basis for such new systems are the myriad of ecologically based agricultural styles developed on hundreds of millions small farms that produce a large share of the food consumed today in the world, mostly without agrochemicals. Agroecology represents this paradigm: a dialogue of wisdoms between traditional agricultural knowledges and modern agricultural sciences that uses ecological concepts and principles for the design and management of sustainable agroecosystems where external inputs are replaced by natural processes. This international Agroecology short course was held from May 2nd to 5th, 2018 at the Center for “Climate Change and Biodiversity in Lakes and Wetlands” located on Polvese Island , Lake Trasimeno, Umbria (Italy), and was designed for scholars, students, farmer...

Climate change is impacting agroecosystems widely. Ecological connectivity makes regions more resilient and hence helps conserve biodiversity and combat climate change, while ecologically sound analysis and management help keep agroecosystems alive. In this context, a bioeconomic approach may help guide the integration of natural and human systems. In Umbria, the origin of this approach was the opening lecture of TreviNatura (Trevi, Italy 25-27 October 2015) delivered by Professor Andrew P. Gutierrez ( CASAS Global ) and titled  " The economy of nature and humans: the role of ecosystem services " that illustrated the often conflicting interaction between humans and nature, and how this interaction can be best understood using bioeconomics, with ecosystem services playing a central role. The region of Umbria in Central Italy is particularly amenable to developing and implementing a holistic approach to the integrated management of agricultural and natural ecosystems, because t...
