Within the framework of the Convention on the Conservation of Biodiversity and the implementation of the program “Agrobiodiversity for the improvement of nutrition, health and quality of life” by joint research of the Department of Acclimatization of Fruit Plants of the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine and the Institute for Biodiversity Conservation and Biosafety of the Slovak Agricultural University in Nitra created the International Network AgroBioNet. The scientific and organizational activities of the network are focused on the development of international cooperation in the field of non-traditional, neglected, and underutilized plant species that contribute to food security. AgroBioNet has more than 50 registered researchers and 250 experts, and unites research institutions, educational institutions, research stations, and farms from 21 countries. Five scientific conferences and 435 published articles for the period 2005–2020 (20 to 50 publications per year) on agrobiodiversity conservation, information on new, non-traditional, neglected, and underutilized plant species have contributed to the expansion of research on their bioecological, biochemical and medicinal properties (including antioxidants) properties, technologies of cultivation and reproduction, practical use and introduction in farms and private gardens.

Genebanks were established out of a recognised need not just to provide genetic variation to support breeding objectives but to prevent crop diversity from being lost entirely for future users. Such conservation objectives may have led, over the past few decades, to a gradually diminishing connection between genebanks and current users of diversity. While there continues to be large-scale distribution of germplasm from genebanks to recipients worldwide, relatively little is known or published about the detailed trends in the demand for genebank materials. Meanwhile, the rapid expansion of the applications and uses of modern genomic technologies and approaches is, undoubtedly, having a transformational impact on breeding, research and the demand for certain genetic resources and associated data. These trends will require genebanks to be responsive and to adapt. They also provide important opportunities for genebanks to reorganize and become more efficient individually and as a community. Ultimately, future challenges and opportunities are likely to drive more demand for genetic diversity and provide an important basis for genebanks to gear up.

Abstract The valorization of plant genetic resources and their direct use in local markets can make a significant contribution to the preservation of agrobiodiversity, while also contributing to the sustainability of rural communities. Indeed, plant genetic resources are a precious source of genes, and they represent an important crop heritage for the quality and sensory characteristics that are required by both farmers and consumers. However, an efficient strategy of agrobiodiversity conservation is strictly connected to product marketability and to consumer preferences. In the present study, choice experiments that involved 920 consumers were carried out to determine their willingness to pay for ancient local tomato varieties (landraces) rather than commercial varieties based on their preferences, and to determine how much they valued these products. The results obtained indicate that consumers are willing to pay premium prices for ancient local tomato varieties (an additional €0.90 kg−1), thus demonstrating their increasing attention to sustainable food and the willingness to contribute to agrobiodiversity conservation and enhancement. These results provide the basis for planning strategies and programs to support the cultivation of these landraces and the development of regional and national markets to acknowledge their characteristics, which will considerably increase the effectiveness and efficiency of conservation strategies.

Selective utilization of limited crop species threatened some other crop species. This trend rendered some crop species into underutilised grain crops throughout.  At this backdrop, the present authors inventorised  agrobioversity in Khandesh region of Maharashtra(India).  The area was visited in different seasons.  The tribal farmers were interviewed to tap down information with respect  to agroclimate, yield, characteristic features etc.  Actual field visits were also made in study area.  The crop species were deciphered using standard state, regional and district floras, besides the manuals and cyclopedia of cultivated plants.  Total 17 exotic crop species were investigated belonging to cereals, millets, pulses and edible oil-yielders.  The data accrued has been evaluated with the relevant national and international scenario.  A need for their conservation is earmarked with particular emphasis on underutilised millets.  The subject-matter is further dilated in view of their importance for the welfare tribal people in the area and developing countries.

The study was conducted in Nawalpur district of Nepal to assess status of on-farm management and associated knowledge of agrobiodiversity. Further, this study identified the farmers perception and their local interventions in on-farm agrobiodiversity conservation and management. The snowball and simple random sampling technique were used to identify the farmers practicing on-farm management and those who do not respectively. The pretested questionnaire was administered to 100 farmers of two villages, 50 from each village, from 2nd to 5th March 2018. Descriptive and analytical statistical tools were used to determine and compare the factors associated with on-farm management of agrobiodiversity. The study revealed that out of 98.0% of the respondents practicing on-farm management, almost all had home garden followed by 74.50% involved in value addition, 59.20% agrodiversity fair, 55.10% Community Biodiversity Management (CBM) and 36.10% travelling seminar. There was a significant relation between the type of the farming system and CBM (at p 0.00), travelling seminar (at p 0.043) and value addition (at p 0.036). The majority of respondents were commercial farmers, they sell what they produce for livelihood, and were practicing on-farm management of agrobiodiversity. Different means of information were used, where major being the information given by the respondents. Lack of government’s technical support and information on Community based Biodiversity Management (CBD), were the major reasons for farmers for not being able to acquaint with it, and practice it on local conditions. Proper training and awareness, agricultural promotion programs are the absolute imperative to improve on-farm agrobiodiversity conservation and management status. SAARC J.

Drought is the main factor of abiotic stress in dryland rice cultivation, responsible for considerable productivity losses and grain quality damages, as well as genetic erosion of local varieties of this crop. The use of indices in the drought tolerance estimation in grains of this crop is acquiring importance for its advantages in the operationalization of tests of comparison between genotypes and their effectiveness in the differentiation of responses to drought stress. Among local dryland varieties of rice preserved by small-scale farmers in far western Santa Catarina, different responses to drought tolerance are expected. The identification of these differential responses is important in the context of agrobiodiversity conservation, genetic improvement, and as an alternative to the effects of climate changes. The objective of the present study was to evaluate thirty-four local varieties of dryland rice from far western Santa Catarina regarding drought tolerance. For this aim, this work used the DTD (Drought Tolerance Degree) methodology. Fifteen varieties showed greater resistance when submitted to a water restriction level of 10% in water moisture. On the other hand, six varieties were more resistant to moderate stress (20%). Finally, three varieties were among the most resistant in the two applied stress levels.

Rural development policies today include significant directions towards ecological transition and sustainability. Biodiversity plays a fundamental role, especially in fragile environments. The North African oases, for example, are socio-ecological structures with delicate balances in terms of natural resources, where the activation of participatory conservation approaches appears today to be very useful, aiming at long-lasting results. This type of approach was applied in the oasis of El Hamma, in Tunisia. The socio-ecological analysis was carried out through semi-structured interviews with different stakeholders of the oasis. The results were used to activate focus groups and to identify, in a participatory way, a conservation strategy for the species and the varieties at risk of erosion or disappearing. From this research, a wide spread of non-traditional date palm and vegetables emerged in a very diverse social context. These products were recognized as highly significant in terms of traditional knowledge by all stakeholders. Therefore, a Maison des semences and a public conservation center for perennial species were created, representing the first step of a participatory conservation model. Seeds of 11 traditional annual species, 10 date palm varieties and, in perspective, many other fruit species and vegetable varieties have been introduced into conservation.

The rich agrobiodiversity of China is under unprecedented threat, experiencing a dramatic loss of many valuable local varieties and wild relatives of main crops. The country's formal conservation system of ex situ genebanks faces serious challenges to address this loss. Community seed banks can play a key role to complement the conservation activities of these genebanks and provide other important collective goods, such as evolutionary services, but although they have been around for some 35 years in various parts of the world, in China they have a much shorter history. In recent years though the number has increased to almost 30 in 2020, in particular due to the efforts of the China Farmers' Seed Network. The community seed banks in the country are very diverse in terms of functions and services, forms of management and institutional linkages. Compared to the most common functions of community seed banks in other countries, China is bringing an important design innovation through two new functions: adding value to seed and produce through innovative marketing strategies, and building regional and national seed system linkages and fostering collaboration. The review of community seed banking not only provides rich empirical evidence, but also makes an important contribution to theory. Building on the achievements of community seed banking in the last decade, there is scope to scale this kind of very valuable agrobiodiversity conservation approach through more effective uptake and support by relevant national policies.

AbstractGenomics-based, longitudinal comparisons between ex situ and in situ agrobiodiversity conservation strategies can contribute to a better understanding of their underlying effects. However, landrace designations, ambiguous common names, and gaps in sampling information complicate the identification of matching ex situ and in situ seed lots. Here we report a 50-year longitudinal comparison of the genetic diversity of a set of 13 accessions from the state of Morelos, Mexico, conserved ex situ since 1967 and retrieved in situ from the same donor families in 2017. We interviewed farmer families who donated in situ landraces to understand their germplasm selection criteria. Samples were genotyped by sequencing, producing 74,739 SNPs. Comparing the two sample groups, we show that ex situ and in situ genome-wide diversity was similar. In situ samples had 3.1% fewer SNPs and lower pairwise genetic distances (Fst 0.008–0.113) than ex situ samples (Fst 0.031–0.128), but displayed the same heterozygosity. Despite genome-wide similarities across samples, we could identify several loci under selection when comparing in situ and ex situ seed lots, suggesting ongoing evolution in farmer fields. Eight loci in chromosomes 3, 5, 6, and 10 showed evidence of selection in situ that could be related with farmers’ selection criteria surveyed with focus groups and interviews at the sampling site in 2017, including wider kernels and larger ear size. Our results have implications for ex situ collection resampling strategies and the in situ conservation of threatened landraces.
