“…An insurance policy against such losses of plant biodiversity is the use of seed banks (Hawkes et al 2012;Raven et al 2013). In this case, seed from populations or species demonstrated to be at extreme risk of extinction can be stored to ensure survival and the long-term maintenance of genetic diversity.…”

Constraints to and conservation implications for climate change adaptation in plants

Contemporary climate change is having widespread impacts on plant populations. Understanding how plants respond to this change is essential to our efforts to conserve them. The key climate responses of plant populations can be categorised into one of three types: migration, in situ adaptation, or extirpation. If populations are to avoid extirpation then migration and/or in situ adaptation is essential. In this review we first articulate the current and future constraints of plant populations, but trees in particular, to the different adaptation strategies (e.g. space availability, rate of change, habitat fragmentation, niche availability). Secondly, we assess the use of the most appropriate methods (e.g. natural environmental gradients, genome and transcriptome scans) for assessing and understanding adaptive responses and the capacity to adapt to future challenges. Thirdly, we discuss the best conservation approaches (e.g. assisted migration, biodiversity corridors, ex situ strategies) to help overcome adaptive constraints in plants. Our synthesis of plant, and particularly tree, responses and constraints to climate change adaptation, combined with the identification of conservation strategies designed to overcome constraints, will help deliver effective management actions to assist adaptation in the face of current and future climate change.

“…Sorghum is used for many purposes, e.g., food, animal feed, fuel, house construction, and fences, and consists of over 20 different species of which some come from East African and some from the Western, Central and Southern regions. Ethiopia holds ex situ 4% of the world's sorghum genetic stock (FAO, 1998 andHawkes et al, 2000). The crop exists in tremendous variety throughout the areas of sorghum production in Ethiopia (Gebrekidan, 1979;de Wet and Harlan, 1971).…”

Although in-situ conservation is increasingly considered an efficient way of conserving plant genetic resources, little is known about the incentives and constraints that govern conservation decisions among small farm holders in developing countries. Using a choice experiment approach, we investigate Ethiopian farmers' crop variety preferences, estimate the mean willingness to pay for each crop variety attribute, and identify household specific and institutional factors that govern the preferences. We find that environmental adaptability and yield stability are important attributes for farmers' choice of crop varieties. Farmers are willing to forgo some income or output in order to obtain a more stable and environmentally adaptable crop variety. Among other things, household resource endowments (particularly land holdings and livestock assets), years of farming experience, and contact with extension services are the major factors causing household heterogeneity of crop variety preferences. Based on our experimental results, we derive important policy implications for on-farm conservation, breeding priority setting, and improved variety adoption in Ethiopia.

“…IVP methods are also essential components of plant genetic resource management and are becoming increasingly important for the conservation of rare and endangered plant species (Almeida et al 2005, Sidhu 2010). These techniques also facilitate the application of genetic manipulation procedures (Ueno et al 1996) and long-term storage (Hawkes et al 2000). In addition, indirect IVP through callus culture is considered to be the most efficient method for crop improvement by the production of somaclonal and gametoclonal variants.…”
