Many Afro-Palearctic songbird migrants have declined, with conservation efforts mainly focused on the restoration of breeding habitat. However, pressures outside the breeding season might play a role. This includes the possibility that local relict populations no longer maintain the original phenotypic variation in migration patterns, with a loss of flexibility. The Great Reed Warbler Acrocephalus arundinaceus kept stable population levels in central and eastern Europe, but was almost extinct in the western part of the breeding range. In the Rhine delta the population declined from 10,000 individuals around 1950, to fewer than 100 at present. Here we document migratory timing, routes, and destinations of members of this remnant songbird population. It turned out that the remaining adults still showed high diversity in migratory phenotypes. This is even true in each of the two last tiny subpopulations in the Netherlands (of 50 and 15 pairs). So, even very small populations maintain the possible adaptive phenotypic variation, and with hindsight this justifies the breeding habitat restoration efforts currently underway.

Challenging the Eurocentric belief that abolitionism was a top-down process issued by colonial powers, this article explores the emergence of personal and group strategies for the emancipation of Black enslaved people in Libya. During the late Ottoman period, Italian antislavery activities operated in Libya and established a mission in Benghazi to host manumitted children referred to as ‘Moretti’ (‘little Moors’). The goal was to make these Moretti a group of local people close to the Catholic Church and the Italian government. The failures of the missionaries to accomplish these aims reveal the strategies and trajectories of Moretti as they negotiated their role in society, especially after Italian occupation in 1911. Historical sources reveal an informal web of solidarity using antislavery societies and creating forms of urban and social autonomy. This article details actions of solidarity among Black enslaved persons that took place in late Ottoman and Italian colonial Libya, which challenges Eurocentric antislavery narratives.

Nearly 500 kite-like structures have recently been discovered in the western Sahara using high resolution satellite images. Although four distinct types with different morphologies have been distinguished, their characteristics, topographical location and orientation in the landscape indicate that they are all most likely hunting traps.

This article centers on the life of Bilal Ould Mahmoud, an enslaved man who became a spiritual authority in the nineteenth-century Sahara. It examines how Bilal's piety allowed him to rise to prominence in a hierarchical context that subjugated him to an inferior position. Yet what makes him so fascinating to study is his ability to achieve the highest station as a Sufi saint without being attached to a Sufi order. Using Bilal's case, this article makes two important contributions to the historiographies of Sufism and slavery. First, it brings fresh perspectives to the studies of Sufism outside of ṭarīqa (Sufi orders). Second, it contributes to the studies of Saharan slavery by exploring enslaved Muslims’ experiences beyond the practice of illicit magic, and also as part of how they exercised their saintly authority as empowered agents. In the process, it analyzes the interplay among Islam, race, and slavery in the nineteenth-century Sahara.

Recent research points to a renewed scholarly interest in the West African Middle Ages and the Sahelian imperial tradition. However, in these works only tangential attention is paid to the role of Muslims, and especially to clerical communities. This essay tackles theoretical and historiographical insights on the role of African Muslims in the era of the medieval empires and argues that the study of Islam in this region during the Middle Ages still suffers from undertheorizing. On the contrary, by using a ‘discursive approach’ scholars can unravel access to fascinating aspects of the history of West African Muslims and in particular to the crucial role played by clerical communities, who represented one node of the web of diffused authority which is characteristic of precolonial West African social and political structures.

Numerous tārīḫs (chronicles) were written in Timbuktu and its surrounding world from the seventeenth to the twentieth century CE. They constitute the Timbuktu tārīḫ tradition. The tārīḫs were embedded in different political projects, which became possible and necessary only under certain historical conditions. Hence, tārīḫs do not all belong to one single genre of historical literature. A chronicle that belongs to the Timbuktu tārīḫ tradition is the twentieth-century Kitāb al-turjumān. It sheds light on history writing in the Sahel during a crucial time, namely European colonial rule and the political realities it gave birth to thereafter. One of modern historians’ most important tasks is precisely to identify, describe, and analyse the different genres within the tārīḫ tradition. We attempt to do that in the case of the Kitāb al-turjumān.

Africanists struggle with Mohamedou ould Slahi’s story for a number of reasons, not the least of which is that the Saharan region is often considered a space betwixt and between. Not only does the Sahara lie between the Maghreb and the Sahel, but Slahi’s experience illustrates how the military and political histories of counterterrorism and the intellectual and social histories of Islamist calls for religious reform are imagined as occurring elsewhere. The upswing in violence in Burkina Faso and Mali, the continued disruptions of Boko Haram, and the deep military involvement and investments in the Sahara remind us that the African continent has been an important site in the global war on terror (Thurston 2017). American and European foreign assistance, often in the form of military aid, has helped expand the surveillance capacities of African states, especially after 2001. In the case of Mauritania, American counterterrorism funds contributed to the consolidation of power in the authoritarian regime of Maaouya Ould Sid'Ahmed Taya, who ruled from 1984 to 2005, while the Mauritanian government ignored demands for democratization from its own citizens and instead pursued repressive policies that accused political opponents of Islamist activity, limiting their freedom of expression (Jourde 2007). Slahi’s story, then, can be seen as part of a much longer history of foreign incursion and neocolonial intrusion into African affairs, as the war on terror has led to a similar bolstering of authoritarian governments, an influx of military aid and funds that encourage corruption, and worrisome increases in weapons at the expense of other needed projects and investment, as happened during the Cold War (Schmidt 2013). Rather than promote economic development and democracy, these policies undermine Africa’s future.

The hyperarid climate of the central Sahara precludes permanent agriculture, although occasional temporary ponds, or etaghas, as a result of rain-fed flooding of wadi beds in the Tadrart Acacus Mountains of the Libyan Sahara allow the pastoral Kel Tadrart Tuareg to cultivate cereals. Geoarchaeological and archaeological data, along with radiocarbon dating and evidence from rock art, however, suggest a much greater antiquity for the exploitation of these etaghas. The authors propose that the present-day cultivation of etaghas mirrors attempts at flood-recession or rain-fed cultivation by late prehistoric Pastoral Neolithic groups, who first exploited residual water resources to supplement their pastoral subsistence practices.

Since 2012, when broadcasting licenses were granted to various private television and radio stations in Mauritania, the controversy around the Battle of Um Tounsi (and Mauritania’s colonial past more generally) has grown substantially. One of the results of this unprecedented level of media freedom has been the propagation of views defending the Mauritanian resistance (muqawama in Arabic) to French colonization. On the one hand, verbal and written accounts have emerged which paint certain groups and actors as French colonial power sympathizers. At the same time, various online publications have responded by seriously questioning the very existence of a structured resistance to colonization. This article, drawing predominantly on local sources, highlights the importance of this controversy in studying the western Saharan region social model and its contemporary uses.

Rain-fed cultivation in drylands—especially in arid and hyper-arid areas—is often considered to play a minor role in human subsistence. Drawing upon the results of ethnoarchaeological research in North Africa, this paper reviews non-irrigated agricultural practices in the absence of anthropogenic water-harvesting structures, and presents a proposal for how such practices can be identified in the drylands of the past. An improved understanding of the long-term development of rain-fed cultivation augments our knowledge of past land-use strategies and can inform future models of sustainable agriculture in some of the world's driest regions.

From the outside, northern Chad has long been seen as an area of lawlessness, defined primarily by its inhabitants’ alleged propensity for raiding and thieving. From the inside, northern Chad indeed appears as an area that thrives on a rhetoric of predation. This, however, is perhaps best understood not in terms of “crime,” but rather as a striving for personal autonomy, as a public denial of reciprocity in a context where notions of bounded moral community and indeed of long-term social strategies of exchange are not much in evidence.
