“…The study area was chosen to encompass the main hydrological study sites investigated in southwestern Niger during the Hapex-Sahel experiment (Desconnets et al, 1997; Leduc et al, 1997). The location is at a significant distance (mean distance of 60 km) from Niamey, Niger's capital, and therefore urban influences (described in Orr, 1995 for firewood harvesting) are minimized in determining the rural land clearance dynamics.…”

“…Findings from this study indicate the importance of forests for rural livelihoods (food and income) in the research area. Past studies highlighted the seasonal fluctuation in food availability and varying reliance on forests for food in different months of the year (Orr 1995;Somorin 2010). This scoping study showed that farm, forests and markets are linked in terms of supplying sufficient food for household consumption throughout the year.…”

“…The question arises whether this transition to a more human-dominated landscape increases or decreases the system's overall resilience. While some authors who mainly focus on agricultural resilience see an increased resilience of the social-ecological system due to improved land management practices (Hiernaux, 1995;Reenberg, 2009;Sendzimir, Reij & Magnuszewski, 2011) and increased agricultural productivity (Mortimore, 2005;Aune & Bationo, 2008;Barbier et al, 2009), other authors more focused on biodiversity and ecosystem functions see a degradation of ecosystem resilience (Poupon & Bille, 1974;Fries, 1990;Schlesinger et al, 1990;Orr, 1995;K€ uppers, 1998;Batterbury et al, 1999;Diouf & Lambin, 2001;Hein, 2006;Gonzalez, Tucker & Sy, 2012;Mensching, 1985;cited in Leisinger & Schmitt, 1995;Herrmann & Tappan, 2013;Angela Hof, in litt. 2009) and ecosystem services (Vetaas, 1993;Lykke, 1998Lykke, , 2000Teklehaimanot, 2004;Wood, Tappan & Hadj, 2004;Augusseau, Niki ema & Torquebiau, 2006;UNEP, 2007;Hiernaux et al, 2009).…”

This review focuses on recent ecological changes in the Sahel. While other recent reviews focused mainly on agricultural changes, remote sensing, and the evolution and distribution of biodiversity, no review focused on ecological changes over time although these changes needed to be summarized to better understand the recent and often dramatic species declines across the Sahel during the last half century. Therefore, I conducted a literature review to summarize these changes, in particular changes to (i) land-use and land-cover, (ii) wetlands, (iii) plants, (iv) birds, especially large and migratory birds and (v) large mammals. The main conclusion is that the exceptionally severe Sahel drought in the late 20th century was extremely detrimental to both human society and nature, but thereafter, rainfall, agricultural productivity and human welfare increased again. As human populations and their ecological footprint increased dramatically, the Sahel's biodiversity continued to become more and more impoverished, whereby woody vegetation, migratory birds, and large birds and mammals suffered particularly severe declines. Besides the agricultural expansion, the other main reasons for these declines are wetland conversions, increased fire frequency, overharvesting, persecution, poisoning and death caused by human artefacts and disturbance. More effective protected areas are urgently needed, which could also generate much needed tourism revenue.
