Green Agriculture: foundations for biodiverse, resilient and productive agricultural systems

There are many visions on how to achieve a sustainable agriculture that provides enough food and ecosystem services for present and future generations in an era of climate change, increasing costs of energy, social unrest, financial instability and increasing environmental degradation. New agricultural systems that are able to confront the challenges of a rapidly changing world require a minimum of ten attributes that constitute the defining elements of a Green Agriculture. A major challenge is to identify a set of thresholds that any agricultural production strategy must meet, beyond which unsustainable trends caused by the farming technologies would lead to tipping-point phenomena. Only those styles of agriculture that meet the established threshold criteria while advancing rural communities towards food, energy and technological sovereignty would be considered viable forms of Green Agriculture. Considering the diversity of ecological, socio-economic, historical and political contexts in which agricultural systems have developed and are evolving in, it is only wise to define a set of flexible and locally adaptable principles and boundaries of sustainability and resiliency for the agroecosystems of the immediate future.
