“…Harnessing indigenous and local knowledge and associated biocultural practices of the local people is an innovative strategy for conservation as well as popularization programs. Since the cultivation of such underutilized and neglected species will empower the indigenous community [5][6][7], suitable polices must be framed at the local and regional level to harness the ILK and biocultural practices of the local people for the exploration, large-scale exploitation, and also for developing the participatory crop improvement programs for the extensive utilization of such traditional and underutilized wild varieties for dietary diversification program. Therefore, conducting periodic awareness program for farmers especially women and other marginalized people is important for encouraging the introduction of various underutilized crops in their family and kitchen garden and also for developing suitable models for crop diversification based on such neglected and wild crops.…”

“…The changing climatic condition is another impediment for food production as it negatively affects the quality and availability of the critical resources as well as the quality and quantity of the agricultural production itself [5]. Since we have to enhance the food production by 70% for meeting the demand of the growing population in 2050, the cultivation of resilient, nutritionally rich, and low-resource intensive crops are of paramount importance for human wellbeing and environmental sustainability [6]. In this context, [7,8] the domestication of undomesticated, wild and neglected crops and exploiting their natural traits to [6].…”

“…Applications of geoinformatics tools such as remote sensing and geographical information system (RS & GISs) can be used for mapping the distribution of neglected and wild crops [29] in various agro-climatic regions of the world, as well as modelling their habitat suitability for identifying the most suitable areas for large-scale cultivation [17,30]. Apart from the large-scale exploration of neglected and underutilized species from diverse habitats and agroecological zones of the world, the conservation of promising species is also equally important for facilitating their future utilization [6,14]. The exploitation of indigenous and local knowledge (ILK) along with the successful incorporation of the biocultural practices of the local people are very much essential for applying the traditional mode of conservation (Figure 4), whereas the exploitation of modern techniques for germplasm storage is also essential for maintaining such vital resources for the future use [13,14].…”

Ensuring the food and nutritional demand of the ever-growing human population is a major sustainability challenge for humanity in this Anthropocene. The cultivation of climate resilient, adaptive and underutilized wild crops along with modern crop varieties is proposed as an innovative strategy for managing future agricultural production under the changing environmental conditions. Such underutilized and neglected wild crops have been recently projected by the Food and Agricultural Organization of the United Nations as ‘future smart crops’ as they are not only hardy, and resilient to changing climatic conditions, but also rich in nutrients. They need only minimal care and input, and therefore, they can be easily grown in degraded and nutrient-poor soil also. Moreover, they can be used for improving the adaptive traits of modern crops. The contribution of such neglected, and underutilized crops and their wild relatives to global food production is estimated to be around 115–120 billion US$ per annum. Therefore, the exploitation of such lesser utilized and yet to be used wild crops is highly significant for climate resilient agriculture and thereby providing a good quality of life to one and all. Here we provide four steps, namely: (i) exploring the unexplored, (ii) refining the unrefined traits, (iii) cultivating the uncultivated, and (iv) popularizing the unpopular for the sustainable utilization of such wild crops as a resilient strategy for ensuring food and nutritional security and also urge the timely adoption of suitable frameworks for the large-scale exploitation of such wild species for achieving the UN Sustainable Development Goals.

“…(Kates et al, 2017). Plant breeders developing climate-resilient crops are increasingly turning to CWR, since traits in these species have the potential to provide valuable adaptations to extreme and variable abiotic and biotic stresses, enhance nutritional quality, and improve a host of other attributes (Hajjar and Hodgkin, 2007;Maxted and Lauvie, 2016;Zhang et al, 2017;Dempewolf et al, 2017;Kell et al, 2017;Migicovsky and Myles, 2017;Monteiro et al, 2018;Nair, 2019).…”

A fter the destructive wildfire seasons of 1999 and 2000 across the western United States, Congress directed the establishment of a native seed and plant materials development program to increase the quality and quantity of native plants available for restoring public lands after wildfires. The Bureau of Land Management (BLM) initiated Seeds of Success (SOS), a US native seed collecting effort (Haidet and Olwell, 2015), as the first step in developing native plant materials that are readily available through commerce or otherwise. The program has focused on common wild native species used for environmental restoration (frequently called "workhorse" species), with collections of seed made from many populations to ensure a broad range of ecotypic as well as genetic variation (BLM, 2018).

Guar resilience in water‐restricted production

Guar [Cyamopsis tetragonoloba (L.) Taub] is an alternative crop in the Southern High Plains that thrives in semi-arid regions, due to its low water input requirements. Field experiments were conducted in 2017 and 2018 at New Deal, TX, to evaluate the response of guar ('Matador') to four levels of deficit irrigation (DI; extreme, 51 mm; severe, 127 mm; moderate, 203 mm; and mild, 279 mm). Soil moisture extraction patterns, plant height, leaf area index, yield components, seed yield, harvest index (HI), agronomic water use efficiency (AWUE), and irrigation WUE (IWUE) were measured among the irrigation levels. In both years, guar grown under extreme and severe DI extracted a major portion of the water from the 50-to-100-cm soil depth. Water deficit reduced plant height, leaf area index, and number of pods per plant in both years. However, the IWUE and 1,000-seed weight increased with reduced irrigation. There were no significant differences in seed yield, HI, and AWUE among treatments as a result of a tradeoff between increased seed weight with low pod production under lower DI treatments and increased pod production with low seed weight under higher DI treatments. Guar extracted water deeper in the soil and produced adequate numbers of pods per plant in balance with the source organ capacity to allocate resources toward optimal seed development. Our research offers valuable information about root exploration and development of larger seeds as compensatory mechanisms that can be further explored to improve the adaptability of guar under water-restricted production conditions.
