“…The study took place in the Beni Isguen oasis (186 ha) and its peripheral extensions, called N'Tissa (855 ha), located south of the town of Ghardaia (Figure 2). This oasis is part of a series of oases of the desert civilization of the Ibadite community (Côte, 2002) all located on the Wadis M'zab and N'Tissa, or their tributaries. The oases are situated along the small irregular valleys on a rocky plateau, which seem to intertwine, hence its analogical name of Chebka (lit.…”

“…This was the case, for example, of large-scale pivot irrigation systems (Otmane & Kouzmine, 2013). Conversely, when oasis communities reappropriated policy discourses that promoted Saharan agriculture and gained access to know-how, technology, markets, land and water, territorial dynamics emerged́ in the ancient oasis as well as in the new agricultural extensions (Côte, 2002;Hamamouche et al, 2018). In the M'Zab Valley, the local community has not only readapted its community irrigated system following the introduction of modern pumping technology while shaping new management institutions, but has also introduced age-old circular practices in the new agricultural extensions based on managed aquifer recharge and sober use of shallow groundwater.…”

One of the most elaborate community initiatives for the management of groundwater consists of managed aquifer recharge and use. In the oases in the M’zab valley in the Algerian Sahara, the collective action that upholds these initiatives has been challenged in past decades by the development of intensive groundwater use with individual pumps in new agricultural areas. However, faced with water shortage and inspired by the more circular irrigation practices in oases, farmers are increasingly creating local use loops in these extension areas by installing recharge devices and using water more carefully. This study analyzes the functioning of the circular managed aquifer recharge and use system in Beni Isguen oasis, and how farmers have reinvented it in agricultural extensions, creatively combining it with modern technologies to engage in market-oriented agriculture. Reinventing circular practices in new agricultural extensions can contribute to more environmentally sustainable forms of agriculture.

“…In the 11th century, five towns called 'ksour' grew around the M'zab river (from upstream to downstream: Ghardaïa, Melika, Béni Isguen, Bounoura and El Atteuf), along with six dams and five palm groves (Cote 2002). Outside the valley, Figure 1 | Geographic localization of the M'zab cities (Bensalah et al 2018).…”

“…This trend was mainly due to population growth and the exploitation of wells in the Albian aquifer varying from 250 to 1,000 m in depth. It should be noted that the population in the M'zab valley increased from 18,000 in 1986 to 135,000 in 2002 (Cote 2002), and it was estimated to be 196,019 inhabitants in 2018. According to Abdellah Haba Aina, an agro-ecologist and former member of the local association for the environment protection of Beni Isguen, 'Before 1985, the only water supply source was the subsurface aquifer and the flood waters that enabled the recharge of the artificial water table.'…”

In the M'zab valley, dry toilets represent an ancestral dry sanitation system, serving as a source of fertilizer thanks to human excrement valorization. However, in the 20th century, local populations began to shun these systems. The objective of this article is to illustrate the importance of dry toilets on agricultural and environmental scales in ancient M'Zab, and the renewal of these systems in response to sanitation problems in the oasis after their decline. The hypothesis put forward is that dry toilets can act as a complementary system to conventional sanitation systems. Data were collected through interviews with the local population. Our results show that the use of dry toilets, and the resulting use of human excrement as fertilizer, has gone through three phases. First, a phase of strong recycling dynamics, followed by a second phase of decline in dry toilet use which is linked to the discovery of the Albian aquifer and flush toilet adoption. The third phase is characterized by dry toilet reuse in response to oasis degradation caused by sanitation and environmental problems. Some oasesians have taken the initiative to revert to dry toilets to ensure oasis system sustainability and to revive the practice of recycling human waste.
