MED-GOLD ( Turning climate-related information into added value for traditional MEDiterranean Grape, OLive, and Durum wheat food systems ) will demonstrate the proof-of-concept for climate services in the agriculture sector by developing case studies for three hallmarks of the Mediterranean food system: grapes, olives, and durum wheat.  Agriculture is primarily climate-driven and hence highly vulnerable to climate variability and change. Evidence suggests that the Mediterranean region is under immediate threat of shifting climate patterns and the associated ecological, economic and social effects. Developing a capacity to turn the increasingly big climate-related data into tailored climate services that can inform decision-making in agriculture is, therefore, a priority both in Europe and worldwide. The long-term goal of this project is to make European agriculture and food systems more competitive, resilient, and efficient in the face of climate change, by using climate serv...

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...

The Mediterranean diet is described by the UNESCO Cultural Heritage of Humanity website ( http://www.unesco.org/culture/ich/en/RL/00884 ) as encompassing more than just food of the various cultures. These diets are embedded in bio-cultural landscapes that are at risk from global markets, industrial agriculture, invasive species and climate change, and yet little research aimed at conserving this Mediterranean agricultural heritage is being conducted. A focus on preserving traditional Mediterranean agricultural systems provides unique opportunities to link UNESCO-SCBD’s Joint Programme on Biological and Cultural Diversity ( http://www.cbd.int/lbcd/ ​) and FAO’s Globally Important Agricultural Heritage Systems initiative (GIAHS, http://www.fao.org/giahs/ ) with the goal of developing strategies and policy to preserve this heritage and the food production systems that are its basis for future generations. An important step in this direction is the development of holistic ecosystem-level a...

The use of marginal land (ML) for lignocellulosic biofuel production is examined for system stability, resilience, and eco-social sustainability. A North American prairie grass system and its industrialization for maximum biomass production using biotechnology and agro-technical inputs is the focus of the analysis. Demographic models of ML biomass production and ethanol farmer/producers are used to examine the stability properties of the ML system. A bio-economic model that maximizes the utility of consumption having the dynamics of MLs and the farmer/producers as dynamic constraints is used to examine the effects of increased conversion efficiency, input costs, risk, and levels of base resources and inputs on the competitive and societal solutions for biomass production. We posit ML abandonment after biofuel production ceases could lead to permanent land degradation below initial levels that prohibit the establishment of the original flora and fauna.
