“…Une évolution assez similaire a été observée dans les zones oasiennes, où l'extension de la surface irriguée sur des franges désertiques s'est réalisée exclusivement à partir des nappes souterraines. Ce type d'investissements a été orienté vers la culture de la pastèque et de variétés marchandes du palmier dattier, créant une rupture marquée entre l'oasis traditionnelle diversifiée de polyculture-élevage et les extensions à base de monocultures supposées plus « modernes » (Hamamouche et al, 2018). Logiquement, les mêmes phénomènes de surproduction des pastèques et d'épuisement des nappes sont apparus, accentués par le climat très aride de ces régions.…”

Le secteur agricole constitue une activité importante au Maroc, représentant 14 % du produit national brut et employant 40 % de la population active. Avec l’émergence de la pandémie de la Covid-19, il a été ébranlé par des incertitudes économiques et par la distanciation physique qui a accentué les contraintes du travail. Toutefois, l’agriculture s’est imposée comme une activité cruciale, puisqu’elle a continué à assurer l’approvisionnement alimentaire à des prix abordables. La pandémie, qui s’est déclarée en une année très sèche, a offert une opportunité pour réviser les principales contraintes auxquelles fait face le secteur agricole : manque d’eau et faible rémunération du travail. Elle a aussi attiré l’attention de l’opinion publique sur les quantités importantes de denrées vivrières importées. La balance des paiements des produits alimentaires demeure négative, malgré des exportations de produits agricoles mises en relief par le discours officiel. En outre, des études récentes ont montré que ces dernières dépendent avant tout d’usages accrus et souvent déraisonnables d’eau souterraine, malgré les subventions à la conversion des systèmes d’irrigation gravitaire vers le goutte-à-goutte. Des suivis d’exploitations ont démontré que ces subventions ont généré une expansion de la surface irriguée avec des cultures à besoins hydriques élevés. Cette situation doit être considérée comme l’opposé de l’objectif recherché : une amélioration de la valorisation de l’eau. Il faut donc reconnaître que l’agriculture de l’ère post Covid-19 devra être différente. Un changement de paradigme doit s’opérer où la valorisation de l’eau pluviale figurera dans les priorités, de concert avec la souveraineté alimentaire. Il doit englober différentes dimensions, comme la préservation de l’environnement, le développement du monde rural et de systèmes alimentaires durables, mais aussi garantir l’inclusion sociale et de meilleures rémunérations du travail agricole, afin d’assurer son attractivité et réduire l’exode rural.

“…At a larger scale, the palm groves in the Algerian Sahara expanded from 5.5 million palm trees in 1959 to 12 million in 2000, and to 17 million in 2011 (see Kuper et al, 2016). In a context of socioeconomic change, massive urbanization (from 24% in 1966 to 68% in 1998 (Côte, 2005)) and social emancipation, these extensions endangered the collective irrigation schemes inside the oases (see Hamamouche et al, 2018). This was sometimes due to destructive water-related interactions (decline in water tables due to excessive pumping or rising water tables of the phreatic aquifer due to receiving the excess pumped water from deep aquifers), but was also linked to the departure of the former sharecroppers towards these extensions (or to other economic sectors), seen as less coercive and more profitable environments (Bisson, 2003).…”

“…The general purpose of these policies has been to guarantee food security by reducing import dependence and developing economically deprived areas (Laoubi & Yamao, 2012). In this sense, the south of Algeria (climatically affected by the Sahara Desert) has been particularly involved in specific programmes within a national strategy known as Saharan agricultural transformation (Hamamouche et al, 2018).…”

Soil Use and Management

Efficient land‐use management could be optimized through appropriate advice regarding land suitability and achieving a reasonable yield while preserving soil and environmental conditions. The main objective of this study was to determine and define those locations capable of wheat cultivation with irrigation in the municipality of N’goussa (Southern Algeria). Expert opinion (EO) method was used for selecting minimum soil data set (MDS‐EO), where six influencing soil properties (sand, pH, salinity, organic matter, gypsum and lime) and other three key parameters (slope, land use/land cover, and proximity to roads and electricity network) were considered important for irrigated wheat cultivation in the study area. Indicators were weighted according to principal component analysis (PCA) loadings and summed. PCA revealed that the selected nine indicators are appropriate for accounting 73.63% of the total variance. Two maps of land suitability were created here (expressed as a soil quality index within a range from 0 to 1) from multivariate analysis and already known standard scoring functions (SSFs) by using two data sets (pure and scored). The distribution of soil quality index (IQI) showed that above 70% of the land was moderately (MS) to highly suitable (HS) for irrigated wheat. The estimation accuracy of soil quality classes has been evaluated using random forests (RF), having as a dependent variable the final class of land suitability used in each map. It was determined that estimation accuracy could reach 60% (pure data set) and 65% (scored data set) at 0.5 cut‐off value for soil quality classes. Final prioritizing according to ranks of sensitivity index (SI) and efficiency ratio (ER) showed that IQI obtained from scored data set is the most suitable approach in soil quality assessment of arid areas. Therefore, it could be applied in southern Algeria for land management, integrated planning and environmental assessments.
