Global energy demand is likely to increase by 50% by 2040. This trend is most pronounced in developing countries with strong population and economic growth. Bioenergy must be part of the response to mitigate global climate change and reduce our dependence on fossil fuels. However, there are concerns over bioenergy production competing with land and water reserves. One solution is the growth of bioenergy feedstocks to produce biogas on semi-arid land that is too dry for conventional agriculture, with plants possessing the highly water-use efficient crassulacean acid metabolism (CAM) form of photosynthesis. These plants use 10-fold less water than common C3 and C4 crops for the same amount of biomass produced. The large amount of water stored in their succulent tissues that is leftover after processing as well as the highly nutritious digestate resulting from the anaerobic digestion (AD) of the plant matter can be used to supplement local agriculture. This research aims to biochemically characterise a selection of CAM species and varieties to determine the most promising biogas feedstock candidate(s) for AD in semi-arid lands.BBSRC priority areas: bioenergy, sustainably enhancing agricultural production, environment and land use, living with environmental change.

到2040年，全球能源需求可能会增加50%。这一趋势在人口和经济增长强劲的发展中国家最为明显。生物能源必须成为减缓全球气候变化和减少我们对化石燃料依赖的对策的一部分。然而，人们担心生物能源生产会与土地和水资源储备竞争。一个解决方案是在半干旱土地上种植生物能源原料，以生产沼气，因为半干旱土地对传统农业来说太干燥了，植物具有高度用水效率的景天酸代谢（CAM）光合作用形式。这些植物使用的水比普通C3和C4作物少10倍，生产同样数量的生物质。加工后剩余的肉质组织中储存的大量水分以及植物物质厌氧消化（AD）产生的高营养物质可用于补充当地农业。本研究旨在通过生物化学方法对一系列CAM物种和品种进行筛选，以确定半干旱地区最有前途的生物气原料候选者。BBSRC优先领域：生物能源，可持续地提高农业生产，环境和土地利用，与环境变化共存。
