Crop wild relatives (CWR) are wild plant taxa genetically related to domesticated crops with trait diversity that can be used in plant breeding to sustain food security. Prioritization is a prerequisite for the cost–effective conservation of CWR as it allows CWR in a checklist to be reduced to a manageable number for active conservation action. In this study, a partial CWR checklist comprising 1651 taxa was compiled for West Africa. Prioritization of the annotated CWR checklist was based on three criteria: (i) economic value of the related crop in West Africa, (ii) CWR genetic closeness to its related crop and (iii) threat status. After applying the three criteria using the parallel method of prioritization, 102 priority CWR were selected for active conservation action. The priority CWR are related to food crops that are nationally, regionally and globally important, such as white guinea yam (Dioscorea cayenensis subsp. rotundata (Poir) J. Miège), cassava (Manihot esculenta Crantz), rice (Oryza sativa L.), wheat (Triticum aestivum L.), cowpea (Vigna unguiculata (L.) Walp.), sweet potato (Ipomea batatas (L.) Lam.), common bean (Phaseolus vulgaris L.) and sorghum (Sorghum bicolor (L.) Moench). This CWR checklist and prioritization will help in the development of a regional conservation action plan for West Africa.

AbstractCrop wild relatives (CWR) are wild plant taxa that have broader genetic diversity than crops hence they are an excellent source of genes and traits to improve crops. The potential value of CWR for agriculture and the need to protect these plants in their natural habitats (in situ) have been recognized globally. South Africa has the richest temperate flora globally, and the checklist of food and fodder CWR for the country considers 258 taxa to be high priority for conservation. A systematic conservation planning approach was used for spatial prioritization for in situ conservation actions for CWR. Protected areas were categorized on the basis of their CWR richness. The Kruger National Park has the highest number of CWR (66 taxa), but most of these are widespread and common. Fifty-seven protected areas, most of which are in the Western and Eastern Cape fynbos, are irreplaceable for protecting a number of endemic and threatened CWR. For priority CWR not adequately represented in existing protected areas, a spatial plan was developed to identify the smallest area that aligns with existing targets for the National Protected Areas Expansion Strategy, that are not transformed in terms of habitat, and that are projected to be climate change resilient. Mechanisms for ensuring uptake of the recommendations for the in situ conservation of CWR have been documented in a National Strategy and Action Plan and these include making information and data available and promoting the inclusion of CWR in current management and monitoring activities.

Tal (mount) Irbid in Irbid city, Jordan, with its continuous human occupation from the Bronze Age until the present, demonstrates the main landmark that has guided the spread of the urban growth of the city. The outcome of studies carried out at Irbid’s historic core, in relation to assessing the loss and degradation of the core’s cultural heritage, shall be analyzed, investigated, and discussed, as also concerns, obstacles, and issues of sustainability to this urban heritage conservation and tourism planning. The paper starts by defining the urban heritage for the historic core, which tends to be set aside, in the city’s rapid development. Actually, the remaining historic buildings can also provide the necessary inter-relationships between the historic core areas and the wider urban context to achieve a sustainable and integrated tourism and conservation action plan for the three heritage neighborhoods around the Tal, while building on tourism opportunities and taking into consideration the needs and the vital role of the local community. The paper concludes that urban heritage conservation and protection of the integrity and identity of the historic core city fabric can assist in its branding, promotion, and management in ways that could enhance the local community belonging, quality of everyday lifestyle, and visitors' experience.

The protective conditions under which callus cultures are grown to prevent microbial contamination and to reduce tissue desiccation cause the accumulation of volatiles in the vessel headspace and reduce the availability of oxygen for respiration. To demonstrate the importance of the gaseous atmosphere to culture growth a study was undertaken on non-morphogenic rice and wheat callus incubated under a number of environmental conditions. Changes in the gaseous atmosphere above rice (Oryza sativa L.) callus during routine culture in a petri dish suppressed growth and promoted necrosis. Incubating callus under a continuous flow of gas mixtures of known composition suggested that the inhibition of growth was caused by the accumulation of high levels of ethylene and to the rapid depletion of oxygen. In order to evaluate the importance of ethylene accumulation aminoethoxyvinyl glycine (AVG), I-aminocyclopropane-I-carboxylic acid (ACC) and silver nitrate (AgNO3) were added to the nutrient medium and ethylene was measured during callus culture. Ethylene restricted callus growth particularly under high (35°C) compared with moderate (25°C) incubation temperatures and under illuminated compared with dark incubation. Under illuminated incubation at 25°C, AVG ( 5 μM ) and AgNO3 (50 μM) improved rice callus growth by 69 and 54% respectively while ACC (100 μM) decreased growth by 15%. Furthermore, rice callus growth was better in large compared with small culture vessels since ethylene accumulation was reduced. In contrast, wheat (Triticum aestivum L.) callus grew well in the petri dish system and released very little ethylene into the culture vessel headspace. Growth was better under illuminated than darkened conditions and under moderate (25°C) compared with high (35°C) incubation temperatures. Furthermore, wheat callus growth was only marginally better in large compared with small culture vessels. Ethylene was not a restrictive factor of wheat callus growth since only low levels were detected in all conditions of incubation. Better control of ethylene and increased oxygen availability could be a way of increasing cell and tissue production for genetic engineering studies of otherwise recalcitrant species such as rice, and may be a way of improving manipulation of wheat.

Globally, the potential of medicinal plants is increasingly being recognized due to their relative availability, particularly in rural areas. This review explored the ethnobotanical and economic values of six selected medicinal plants widely used to treat and manage childhood diseases in South Africa. Acalypha glabrata, Aloe maculata, Datura stramonium, Gomphocarpus fruticosus, Rhoicissus tridentata and Vachellia karroo were selected based on their high relative frequency of citations for treating a wide range of diseases. Information was obtained from various scientific databases and ethnobotanical books. In addition to being popular for treating childhood diseases, the selected medicinal plants possess diverse applications in traditional medicine for other age groups, highlighting their general therapeutic values. This translates to extensive harvesting, trading and consumption of these plants in order to meet demands on local levels. Currently, empirical data on the economic value of the selected plants remain poorly reported. Even though South Africa has many laws to conserve and promote indigenous knowledge and medicinal plants, their commercialization remains low. Particularly the cultivation of the selected plants needs to be promoted under a participatory management action plan to stimulate the economy of the disadvantaged. A collaborative research framework for the inclusive transformation of indigenous medicinal plants is recommended to reveal their concealed beneficial properties.

The genetic diversity found in populations of crop wild relatives is an essential resource for future crop breeding, but populations are at risk of loss before germplasm has been fully conserved in genebanks. This chapter describes best practice for targeting and identifying species, and review knowledge about the variation in wild plant populations to guide the timing of collecting and approaches for genetic sampling. Indicators are presented for seed quality, ripeness and dispersal. Techniques for collection of seed, herbarium vouchers and associated data are reviewed with examples drawn from the Adapting Agriculture to Climate Change (Crop Wild Relative) project. Further research is needed to find optimal approaches for handling of seed to ensure high longevity of seed collections, and improved tools are needed to guide sampling of genetic diversity of crop wild relatives.

AbstractCrop wild relatives (CWR) are valuable gene pools for crop improvement and offer unique potential and opportunity for enhancing food security and adaptation to climate change. However, current actions towards conservation of plant genetic resources in Zambia do not adequately cover CWR occurring in the country. The article describes the process leading to the development of a national strategic action plan (NSAP) for the conservation and sustainable use of priority CWR in Zambia. Based on 59 prioritized crops, a partial checklist of 459 CWR taxa was generated from the national flora checklist of 6305 taxa. The generated CWR taxa were prioritized based on the socio-economic value of the related crop, their utilization potential in crop improvement, relative distribution and threat status to produce 30 prioritized CWR taxa. Occurrence data were compiled for all CWR inventory taxa and used in spatial analyses to establish species distribution, species richness, gaps in in situ conservation and genebank collections, and to identify priority sites for in situ conservation and ex situ collecting. Consistent with the national developmental agenda, along with the contribution of national stakeholders, spatial analyses of occurrence data of priority CWR taxa are valuable input for the development of the NSAP for the conservation and sustainable use of the priority CWR.
