Access to well-informed agricultural service providers and clear unbiased education materials will simplify the transition to sustainable agricultural, reduce uncertainty, and increase the likelihood of success. 6 TABLE OF CONTENTS Forward No-till and cover crops are among the most cost effective tools to reverse soil and carbon loss and improve soil health; the economic, agronomic and environmental benefits of these practices are well known within the farming community. Transitioning from conventional farming to no-till, and incorporating the use of cover crops, requires a higher level of management and demands a substantial investment in time to learn the information necessary to succeed. Farmers face hurdles including field soil preparation, equipment purchasing decisions, and management of other impacts on agronomic practices. For many farmers, lack of knowledge is a barrier to implementation. This manual is designed to help agricultural service providers and farmers as they strive to implement new practices. It is designed for individuals already convinced of the merits of no-till and cover crops, but unsure how to implement these practices. This is a how-to manual This manual contains...

We call for a third-generation of bioenergy crops, or biomass crops, to help move society towards a sustainable bioeconomy and global food security. Third-generation biomass crops should be capable of producing both food and raw materials. Such flexibility would allow farmers to respond to global markets and buffer global food security. At the same time, third-generation biomass crops need to increase the sustainability of agriculture. To reach such ambitious goals, new biomass crops have to develop de novo from promising perennial wild species. Keywords: opinion; de novo domestication; biomass crops; perennial bioenergy crops; bioeconomy; third-generation biomass crops The dilemma of devoting productive land to fuel vs. food has made bioenergy crops controversial. The critique of first-generation bioenergy crops is particularly strong [1]. Crops such as maize, rapeseed, sunflower, sugar beet and wheat were domesticated for direct human consumption, or adapted for indirect human nutrition, through the feeding of farm animals.

Noting the contrast between nature’s prairie and annual grain monocultures the reality of nature’s wisdom and the failure of human cleverness was clear. Perennial grain polycultures research began, but with full awareness that science is embedded in dominating social organizations which must be well understood if we are to address the countless problems in our climate changing ecosphere. To that end I will give a brief history of our origins and argue for a information rich creaturely world view to replace the industrial mind. John Head, Kansas University Is the Future of Agroecological Governance also Perennial? In addition to the scientific innovations that will allow us to give an affirmative answer to the central question of this conference – “Is the Future of Agriculture Perennial?” – we must also consider and design legal and institutional innovations, especially at the global level, that can facilitate an effective transformation from modern extractive agriculture to agroecological husbandry. These reforms in agroecological governance should give special emphasis to (i) reconceptualizing state sovereignty to reflect 21st- century realities and (ii) introducing new legal entities (“eco-states”) with authority to manage agroecological matters in ways that will address the soil and climate crises.

It presents the principles, practices and technologies for the sustainable and profitable production of annual and perennial crops to meet food, feed, energy, fibre needs and foster economic growth in a world where the global population is expanding, the climate is changing, dietary patterns are evolving and natural resources are growing scarce. These issues are presented both in terms of the projected impacts of climate change (Chapter B1-2) and crop systems (Chapter B1-3). The module also describes the off-farm elements that can enable farmers to adopt climate-smart crop production practices (Chapter B1-4). A fundamental challenge is to address the needs of broad and diverse groups of stakeholders by identifying an appropriate set of climate-smart practices. This requires knowledge of the type and extent of expected changes in the climatic variables that affect crop production; the trade-offs and synergies between local climate and international markets; and the best adaptive management options for a given context. This module does not provide a rigid blueprint for action. There is no standard formula that can be applied for every context.

Ryan 1,* 1 Section of Soil and Crop Sciences, Cornell University, Ithaca, NY 14853, USA; [email protected] 2 ISARA-Lyon, 69007 Lyon, France; [email protected] (V.D.); [email protected] (C.D.) 3 Cornell Statistical Consulting Unit, Cornell University, Ithaca, NY 14853, USA; [email protected] * Correspondence: [email protected] Authors contributed equally. y Received: 1 October 2019; Accepted: 11 November 2019; Published: 14 November 2019 Abstract: Perennial grain crops are currently being developed, yet little is known about farmer interest in these new crops. We conducted an online survey in France and the United States to evaluate interest in perennial grains. Results show that 57% of the farmers who responded reported they were “interested” or “very interested” in growing perennial grains, whereas 41% reported they needed more information. Respondents consistently ranked “to increase or maintain farm profitability” and “to improve soil health” among the top reasons why they were interested in growing perennial grains. Reasons why farmers were interested, as well as their concerns about growing perennial grains, differed by country and farm type (i.e., conventional vs. organic). More farmers in France than in the United States ranked “to reduce labor requirements”, and more conventional farmers than organic farmers ranked “to reduce inputs” among their top reasons for their interest. Farmers were also asked about integration strategies and management.

  • Perennial Staple Crops of the World
    Perennial Staple Crops of the World This is a companion piece to “Climate Stability with ‘Permanent Agriculture,’” an article that appeared in the Spring 2011 issue of the Permaculture Activist. That article laid out the potential for perennial farming systems like agroforestry and perennial crops to sequester carbon while providing multiple social and ecological benefits. This article reviews perennial staple crops, a little-known group of species with tremendous potential to address world problems. Perennial Staple Crops are basic foodstuffs that grow on perennial plants. These plant sources of protein, carbohydrates, and fats can be harvested non-destructively – that is, harvest does not kill the plant or prevent future harvests. This group of crops includes grains, pulses (dry beans), nuts, dry pods, starchy fruits, oilseeds, high-protein leaves, and some more exotic products like starch-filled trunks, sugary palm saps, and aerial tubers. These trees, palms, grasses, and other long-lived crops offer the unique possibility of crops grown for basic human food that can simultaneously sequester carbon, stabilize slopes, and build soils as part of no-till perennial agricultural systems. Such production models seem the most likely of all regenerative farming practices to approach the carbon sequestering capacity of natural forest, because they can mimic the structure of a forest most closely. Perennial staple crop systems are resilient in the face of extreme weather, surviving drought, flooding, and storms better than most annuals. These food forests can be long-lived, no-till, and low-maintenance – which sounds like a rather utopian base of subsistence. They do however have harvesting and processing challenges – for example most peach palm varieties have tall, very spiny trunks that must be climbed for harvest (both dwarf and spineless forms have been selected, but not yet one with both qualities).
