“…The role of increased woody vegetation in fields was clearly central in the effort to build community resilience to climatic and economic shocks in Niger. The benefits of different tree and shrub species in the landscape are now becoming welldocumented in the West African Sahel (Niang et al 2014b;Sinare and Gordon 2015;Wade et al 2018) and East Africa (De Leeuw et al 2014). Despite the positive example given above from Niger, it is important to keep in mind that increased vegetation cover as such does not necessarily translate into improved livelihood conditions for people.…”

“…This will also indirectly increase soil microbiotic biodiversity and activity (Lange et al 2015). Experimental field trials have already been used and are currently being scaled out, to inform GGW decision makers as to how to increase biodiversity along the GGW path (Wade et al 2018). It has also recently been suggested that planting fast growing and/or flowering shrubs (the latter to support apiculture) in addition to trees could also diversify environmental and social benefits (O'Connor and Ford 2014).…”

“…Collaboration across knowledge systems includes different tasks in different phases of a decision process, from mobilization of knowledge in a form that can be shared across knowledge systems to the application of shared knowledge that has been translated, negotiated, and synthesized with respect for differences in knowledge, and with some contradictions kept (Tengö et al 2017). Along the GGW in Senegal, traditional knowledge gained through ethnobotanical studies has been instrumental in guiding the choice of tree species for reforestation (Niang et al 2014a, b;Wade et al 2018). In general, multistakeholder participatory approaches are central in the framework to contribute to resilience building by creating a shared systems vision that encompasses complex adaptive systems thinking, enabling broad and strategic participation, and identifying relevant governance arrangements which may be polycentric (Biggs et al 2012) or include other forms of governance that may be more appropriate for the particular social-ecological context (Bodin 2017).…”

The Great Green Wall for the Sahara and the Sahel Initiative as an opportunity to enhance resilience in Sahelian landscapes and livelihoods

Over the past 50 years, a large number of development initiatives have addressed the diverse social and ecological challenges in the Sahel, often focusing on a single entry point or action, resulting in only a limited degree of success. Within the last decade, the international development discourse has evolved to incorporate resilience thinking as a way to address more complex challenges. However, concrete examples as to how to operationalize resilience thinking are lacking. The Great Green Wall for the Sahara and the Sahel Initiative (GGW), a pan-African program with a strong reforestation focus, is the latest and most ambitious of these development programs to date. The GGW represents an ideal opportunity to apply resilience thinking at a large scale, but in order to do so, it must intelligently gather and centralize pre-existing interdisciplinary knowledge, generate new knowledge, and integrate knowledge systems to appropriately navigate future uncertainties of the diverse social-ecological systems along its path. Herein, after a brief description of large-scale reforestation history in the Sahara and Sahel and the conceptual evolution of the GGW, we propose a transdisciplinary research framework with resilience thinking at its core. It includes analysis of complex social-ecological systems, their temporal and spatial cross-scale interactions, and outcomes focused on the supply of abundant, diverse, equitable, and durable ecosystem services to support livelihoods in the region. If the research areas that comprise the framework were to be properly addressed, they could conceivably guide GGW actions in a way that would contribute to desirable future pathways.

“…Balanites aegyptiaca is an endemic sahelian species with a strong colonizing ability that ensure stable populations for this species even though regeneration happens rarely (Müller, 2008;Sop et al, 2011). In many studies carried out in some regions of West Africa Sahel, Balanites aegyptiaca, were mentioned exhibiting moderate survival rates (Wade et al, 2018) and also having vastly increased in number, to be the dominant species. This has been observed at Oursi in northern BF (Maranz, 2009).…”

Understanding woody vegetation composition and structure is important for leading management decisions in the Sahelian vulnerable zones. The objective of the study was to better knowledge woody vegetation structure and richness in natural vegetation and cropland. The study area is Kékénéné village located in Soum province, surroundings Djibo in northern Burkina Faso. In total 54 sample plots were surveyed by means of a botanical inventory of woody vegetation species. All trees ≥ 10 cm dbh were measured. The vegetation structure pattern analyzed were diameter at breast height (dbh), basal area, relative dominance, and relative density, Importance Value Index (IVI) and Family Importance Value (FIV). In total 658 trees recorded was belonging to 21 species, 9 families in natural vegetation and 11 species, 5 families in cropland. Tree density was 15.7 stems/ha and 3.7/ha respectively in natural vegetation and cropland. Tree basal area was 0.54 m² ha-1 for cropland and 0.35 m² ha-1 in natural vegetation with a mean dbh of 3.5 cm for the two occupation types. The most importance family according to FIV was Balanitaceae in cropland and Combretaceae in natural vegetation. The Sorensen' similarity coefficient of family in the two landscapes is lowest than 0.5 which means that the similarities in species family are low between the two occupation types. In natural vegetation, Anogeisus leiocarpus and Balanites aegyptiaca were the most important species in relation to IVI, while in cropland Balanites aegyptiaca, Acacia senegal and Acacia seyal were the most important species. Results reveal an abundance of Balanites aegyptiaca in both cropland and natural vegetation in the study site. Given its high socioeconomic value in this region, this tree deserves to be more valued in a perspective of management and sustainable use in Kékénéné village.
