“…High-yielding, deep rooted, perennial, herbaceous plants prevent erosion, build soil organic matter, support diverse belowground microbial communities, provide ecosystem services, and produce seeds and biomass that can be harvested mechanically (e.g., Crews & Cattani, 2018;Crews et al, 2016;DeHaan et al, 2016;Glover et al, 2010;Pimentel et al, 2012). There are various ways in which perennial crops can be incorporated into agricultural systems, including rotation with annuals, in perennial monocrops, or in perennial polycultures (Cattani, 2014;Ryan et al, 2018).…”

Societal Impact Statement Agroecosystems are constantly evolving to meet the needs of a growing population in a sustainable manner. Concerns about ecological impacts of agriculture, including soil loss, have focused attention on crops that provide both agricultural products and ecological services. Perennial, herbaceous crops that live for multiple years and can be harvested mechanically produce large root systems that may reduce soil loss; however, these species are largely absent from agriculture. The diversity of wild, perennial, herbaceous legume species documented by the Perennial Agriculture Project Global Inventory (PAPGI) increases resources available to breeders of perennial, herbaceous legumes, and raises awareness about untapped wild plant diversity in future crop development. Summary Concerns about soil health and stability are focusing attention on crops that deliver both agricultural products and ecological services. Deep rooted, perennial plants that build soil organic matter, support diverse belowground microbial communities, and produce edible seeds are key components underpinning ecological intensification; however, few perennial, herbaceous crops have been domesticated for food. To facilitate development of edible, perennial, herbaceous crops, including perennial grains, we constructed an online resource of wild, perennial, herbaceous species—the Perennial Agriculture Project Global Inventory (PAPGI; http://www.tropicos.org/Project/PAPGI). The first component of this project focuses on wild, perennial, herbaceous Fabaceae species. We extracted taxonomic names and descriptors from the International Legume Database and Information Service. Names were added to PAPGI, a special project within the botanical database TROPICOS, where they link to specimen records and ethnobotanical and toxicological data. PAPGI includes 6,644 perennial, herbaceous Fabaceae species. We built a searchable database, a framework for the ongoing incorporation of more than 60 agriculturally important traits for perennial, herbaceous legumes. Here we highlight food and forage uses for 314 legume species, and toxicological data for 278 species. The novel contribution of PAPGI is its focus on wild, perennial herbaceous species that generally have not entered the domestication process but that hold promise for development as perennial food crops. By extracting botanical information relevant for agriculture we provide a dynamic resource for breeders and plant scientists working to advance ecological intensification of agriculture, and for conservation managers working to preserve wild species of potential agricultural importance.

“…It is a form of ecological intensification, a process that harnesses ecological services to sustain production, support ecosystems, and minimize anthropogenic effects of agriculture [8] . As agroforestry research expands [7], [9] , attention is focusing in part on the role of herbaceous perennial crops to improve agriculture sustainability [10], [11] . Perennial plants with deep, robust root systems prevent erosion, sequester carbon, and absorb and retain more water [12], [13] ; they access and absorb minerals housed deep in the soil, incorporating them into the plant body [14] .…”

Malnutrition is a global public health concern and identifying mechanisms to elevate the nutrient output of crops may minimize nutrient deficiencies. Perennial grains within an agroforestry context offers one solution. The development and integration of perennial crops for food has critically influenced dialogue on the ecological intensification of agriculture and agroforestry.However, the nutrient compositions of wild, perennial, herbaceous species, such as those related to the common bean ( Phaseolus vulgaris ) are not well known. In this study, seed amino acid and ion concentrations of perennial and annual Phaseolus species were quantified using ionomics and mass spectrometry. No statistical difference was observed for Zn, toxic ions (e.g. As) or essential amino acid concentrations (except threonine) between perennial and annual Phaseolus species. However, differences were observed for some nutritionally important ions among and within lifespan groups. Ca, Cu, Fe, Mg, Mn, and P concentrations were higher in annual species.Intraspecific variability in ion concentrations and amino acids was observed within species; further, ion concentrations and amino acids differ among annual species and among perennial species. Ion and amino acid concentration appear to be largely independent of each other. These results suggest variability in ion and amino acid concentrations exist in nature. As new crop candidates are considered for ecological services, nutritional quality should be optimized to maximize nutrient output of sustainable food crops.
