“…Whether BSCs are deemed facilitative or inhibitory for later successional vegetation may depend on how exhaustively the interaction between plants and BSCs is investigated. In fixedsand areas, BSCs may in some cases reduce infiltration (inhibitory effect) (Mitchell et al, 1998), but they also increase soil stability and serve as an N source for surviving and recolonizing trees (facilitative effects) (Tateno et al, 2003;Uchida et al, 2000). The BSC bacterial communities in the Figure 8.…”

Abstract. Knowledge of structure and function of microbial communities in different successional stages of biological soil crusts (BSCs) is still scarce for desert areas. In this study, Illumina MiSeq sequencing was used to assess the compositional changes of bacterial communities in different ages of BSCs in the revegetation of Shapotou in the Tengger Desert. The most dominant phyla of bacterial communities shifted with the changed types of BSCs in the successional stages, from Firmicutes in mobile sand and physical crusts to Actinobacteria and Proteobacteria in BSCs, and the most dominant genera shifted from Bacillus, Enterococcus and Lactococcus to RB41_norank and JG34-KF-361_norank. Alpha diversity and quantitative real-time polymerase chain reaction (PCR) analysis indicated that bacterial richness and abundance reached their highest levels after 15 years of BSC development. Redundancy analysis showed that silt + clay content and total K were the prime determinants of the bacterial communities of BSCs. The results suggested that bacterial communities of BSCs recovered quickly with the improved soil physicochemical properties in the early stages of BSC succession. Changes in the bacterial community structure may be an important indicator in the biogeochemical cycling and nutrient storage in early successional stages of BSCs in desert ecosystems.

“…The idea was initially proposed in the 1980s over concerns of desertification and received renewed attention in the early 2000s as a potential adaptation to moderate the impacts of projected future climate changes. While the plan has suffered from a lack of funding and political will, we believe the central idea of the GGW has significant potential for adaptation: similar programs have been developed in other regions (e.g., China, New Zealand) and have been successful in reducing, and in some cases reversing, desertification [16,17,19,[22][23][24][25][26]. However, we believe that the GGW needs modifying if it is to be effective, obtain the support of local communities and leverage international support.…”

Abstract:The Great Green Wall (GGW) has been advocated as a means of reducing desertification in the Sahel through the planting of a broad continuous band of trees from Senegal to Djibouti. Initially proposed in the 1980s, the plan has received renewed impetus in light of the potential of climate change to accelerate desertification, although the implementation has been lacking in all but two of 11 countries in the region. In this paper, we argue that the GGW needs modifying if it is to be effective, obtain the support of local communities and leverage international support. Specifically, we propose a shift from planting trees in the GGW to utilizing shrubs (e.g., Leptospermum scoparium, Boscia senegalensis, Grewia flava, Euclea undulata or Diospyros lycioides), which would have multiple benefits, including having a faster growth rate and proving the basis for silvo-pastoral livelihoods based on bee-keeping and honey production.

“…Desertification is one of the major environmental problems worldwide (Reynolds et al, 2007) and it occurs in almost every habitable region such as North America (e.g., Schlesinger et al, 1990;Li et al, 2008;Ravi et al, 2009), Africa (e.g., Thomas et al, 2008;Wang et al, 2010a) and northern China (e.g., Chen et al, 1996;Mitchell et al, 1998, Liu et al, 2012. The deserts in northern China are expanding at an estimated rate of 2100 km 2 ·year -1 (Chen et al, 1996;Mitchell et al, 1998).…”
