The Given

Four on-farm plantations (KRNAP Vrchlabí, the Orchard of Reconciliation in Neratov, Podyjí National Park, and Šumava National Park) were successfully established in a traditional form, with large orchard trees on seedling rootstocks. Certain accessions (cultivars) for on-farm conservation in the given locality were selected, according to the incidence and presentation of genotypes in these particular areas. This information was obtained by localization of fruit trees <I>in situ </I>and the determination of certain cultivars. Nursery stock production for onfarm plantations is described. Because of the longevity of the plantation, seedling rootstocks were used for the production of planting materials for the on-farm plantations. Techniques of on-farm plantation establishment and orchard management are stated within the paper. Four established on-farm plantations have ensured the long-term preservation of landraces in their original areas.

Interest in local landraces has unfortunately decreased over, the last decades, in which they have been continuously subjected to a high genetic erosion in favour of new modern varieties. Within the Puglia region (S-E Italy), Foggia province was found to be the richest in vegetable landraces. In the present study, six garlic landraces collected from this area have been assessed for their chemical composition (minerals, organic acids, free sugars, volatile, and phenolic compounds) along with their main morpho-biometrical traits. A commercial genotype was also considered as a reference standard. The landraces show a large variability, but in general high morphological standards, high levels of cations and phenols, and low levels of volatile-(S)-compounds in comparison with the commercial genotype and the literature values. ‘Aglio di Peschici’ and ‘Aglio Rosso di Monteleone di Puglia’ are very rich in minerals and phenols (mainly ferulic acid and iso-rhamnetin). This increase in knowledge on the chemical properties of these garlic landraces could represent a tool for encouraging the consumption of a food product. At the same time, the consumption of these landraces would stimulate their cultivation and could highly contribute to protection against the risk of erosion of agro-biodiversity by their in situ/on-farm conservation.

Conservation of crops is based on <I>ex situ </I>collection into gene banks. Additionally, crop’s wild relatives can be conserved <I>in situ</I>, and landraces and obsolete cultivars also can be conserved using the on-farm method. The definition and methodology of on-farm conservation is discussed. On-farm conservation has been set up in the Czech Republic as model examples in several institutions dealing with nature protection, education, cultural conservation, as well as by some private farmers. Problems, plus positive and negative experiences are presented. On-farm conservation in open-air-museums in the natur (skansens) as well as in the national parks, seem to be suitable ways forward for the Czech Republic.

Abstract The critically endangered Brazilian pine, also called araucaria, (Araucaria angustifolia (Bertol.) Kuntze) is a key species of the Araucaria moist forest (AMF, Mixed Ombrophilous Forest). Illegal timber extraction, agricultural conversion and severe degradation have reduced the AMF to only 13 per cent of its original cover, with climate change imposing additional challenges for cold adapted species such as araucaria. Previous studies have assessed climate change impacts on A. angustifolia, but have been limited by analysis constraints. Here, we used a machine learning technique to understand how land use and climate change might affect the distribution of A. angustifolia, and to evaluate the effectiveness of existing protected areas (PAs) to conserve this species. Our results demonstrated that despite the recent efforts to conserve the Atlantic Forest, conversion of natural habitats into forest plantation still occurs within araucaria’s distribution range. Our model predicted a drastic reduction in environmentally suitable areas for this species of up to 77 per cent in the coming decades. Also, the existing PAs show low efficacy to protect suitable areas in the future. Combined, these results suggest that A. angustifolia will be under great threat within the next few decades and the development of conservation strategies to save this species is essential. Ideally, the conservation programs should integrate in situ and on farm approaches, including forest management strategies. Although in situ strategies play an important role as gene banks, on-farm strategies can be used to promote the restoration and expansion of A. angustifolia populations in the areas predicted as suitable.

The Impact

Farmers use various seed systems to obtain seeds for their next crop. The diversity of seeds determines, together with other aspects of the farming system, the biodiversity in farmed areas. Conservation strategies for crop genetic resources distinguish ex situ, on-farm and in situ components. The on-farm management of such resources is highly influenced by the seed systems that farmers use. Next to primary and secondary centres of diversity, this chapter introduces a tertiary source of diversity, based on the creation of new diversity through modern breeding. The impact of different seed systems on the management of crop genetic diversity is also analysed.

Genetic erosion can result in the loss of sorghum landrace genetic diversity. In the study areas, although it is generally believed that genetic erosion had occurred, there are no data on its amount and extent. Thus, this study is aimed to assess farmers’ perception about the use of sorghum landraces and their genetic erosion and to identify suggested reasons for the replacement of sorghum landraces. To this end, a field survey of 1200 farmers, randomly selected over the three districts (Tenta, Mekdela, and Delanta) during 2006 to 2015/2016 main cropping seasons, was undertaken. Structured questionnaire survey of households, focused group discussions, key informant interviews, and field observations were used to collect data. Moreover, the data for samples collected during 1980 were obtained from the Ethiopian Biodiversity Institute (EBI). Sorghum landrace history profile analysis indicated that there was an insight in the use of local varieties among local farmers over the past three or above decades. However, there is a reduction trend due to the different selection criteria described by farmers. “Kokita,” “Merar,” “Marchuke,” “Tinkish” (except for “Necho-Tinkish” and “Jofa-Tinkish”), and “Fesho” were totally excluded (lost) by local farmers attributed by home consumption preferences. The interviewed farmers indicated that genetic erosion had occurred. Genetic erosion of 100% was observed in white sorghum in Mekdela and 66.7% in Delanta and Tenta districts. Likewise, genetic erosion of red sorghum, 25%, 20%, and 75%, respectively, was detected in Tenta, Mekdela, and Delanta. For yellow sorghum grains, genetic erosion was 33.4% in Tenta and 66.7% in Mekdela and Delanta. Genetic erosion for “Tinkish” was found to be 66.7% in Tenta and 50% in Mekdela and Delanta. Based on farmer responses, genetic erosion was attributed to reduced benefits from landraces, drought, climate change, market price and demand, and reduction in land size. The actions of both natural and conscious selection on farm were also discussed in detail as genetic erosion scenarios. Therefore, attention should be given to conservation of farmers’ varieties in which involving farmers’ participation is very important in order to use their indigenous knowledge for conservation of FVs and on-farm conservation strategies should be practiced for FV sustainable use. Thus, genetic resource conservation is attained.
