“…The Islamic theory that encourages procreation in order to expand the Muslim community has also aided population growth which provoked a negative trend in land use/cover patterns. Fallow was also negated as a result of inheritance which rendered some hitherto, family farmlands to individually owned ones [18] (Issiaka et al, 2012).…”

Keita region is largely dependent on agriculture and livestock as the main economic activities with about 90% of the population are actively engaged in rural activities. However, these activities are dwindling at a rate that corresponds with increase in the ecosystem's vulnerability. The following study focused on land use/land cover change in Keita. The study aims to better understand changes through diachronic analysis by integrating remote sensing and GIS. There was an interpretation of satellites imagery (1975, 1984, 1995 and 2001), and statistical techniques were used to provide quantitative analysis of land use/cover change information and drivers underlying in the study area. The changes are affected by simultaneous influence of successive droughts (1973-1974 and 1983-1984) that have transformed ecological balance, anthropogenic and livestock impacts, ecosystems degradation and policies. The land use temporal dynamics are undergone continual degradation of vegetation, the state of land saturation results in conflicts between farmer and herders, the drop in grazing areas, bare land expansion, the erosion of stream bed, and the decline in flooded plain.

“…Four geomorphological units stand out: plateau, slope, glacis and valley [12] (p. 15). In terms of water resources, the area has a semi-permanent stream in the Maradi valley that irrigates its eastern part for around 15 km, and a few temporary pools in the Maradi goulbi [27,28]. Agroforestry parks and village forests along the valley are the two main types of forest formation.…”

Modeling the Spatio-Temporal Dynamics of Village Land in an Agropastoral Area of Niger for a Contextualized Diffusion of Agroecological Intensification Options

Spatio-temporal variability and dynamics in Sahelian agro-pastoral zones make each local situation a special case. These specificities must be considered to guide the dissemination of agricultural options with a view to sustainable development. The territorial scale of municipalities is not sufficient for this necessary contextualization; the scale of the “village terroir” seems to be a better option. This is the hypothesis put forward by the Global Collaboration for Resilient Food Systems program. By analyzing the links between farm managers and their cultivated land, as well as the spatio-temporal dynamics of “village terroirs” in three regions of Niger (Maradi, Dosso and Tillabéri), this study provides evidence of the existence and functional usefulness of the village terroir for farmers, their land management and their activities. It demonstrates the usefulness of contextualizing agricultural options at this scale. It is based on data collected through participatory mapping and surveys. Their analysis elucidates the links between “terroirs village” and the specific functioning of the agro-socio-ecosystems acting on each of them, thus laying the systemic and geographical foundations for a model of the spatio-temporal dynamics of “village terroirs”. This initial work has opened up new perspectives in modeling and sustainable development.

“…Des telles dépendances vis-à-vis de la biodiversité conduisent à la dégradation des écosystèmes forestiers. Des nombreuses études dans la bande sud du pays ont montré une dégradation des écosystèmes forestiers suite aux changements importants dans l'occupation des sols, à la surexploitation des ressources naturelles et aux sécheresses des dernières années (Mahamane et al, 2007 ;Issiaka et al, 2012 ;Hamidou et al, 2012 ;Sadda et al, 2016). Cette dégradation a conduit par endroit à la raréfaction et à la disparition de nombreuses espèces ligneuses des écosystèmes (Larwanou and Saâdou, 2005 ;Moussa et al, 2016).…”

The objective of this study is to contribute to the sustainable management of the Dasga palm trees forest by analyzing the phytodiversity and ecological parameters guiding the distribution of vegetation. The methods of phytosociological survey and multivariate analyzes were used. The vegetation surveys were carried out according to the sigmatistic approach of Braun-Blanquet (1932) and the multivariate analysis techniques used were those relating to factorial analysis of relaxed correspondence (DCA) and canonical correspondence analysis (CCA). A total of 144 species belonging to 100 genera and 50 families were recorded from 68 plots. This flora is 408 dominated by a strong presence of therophytes and species with broad pantropical and palaeotropical distribution, thus showing an arid and perturbed environment. The multivariate analyzes (DCA and CCA) sow among the variables tested; only the slope and the crops were determinants in the structuring of the vegetation by the Monte Carlo permutation test. These ecological variables would appear to be the major parameters of species distribution. Thus the understanding of the relationships between vegetation and ecological parameters can be used as a tool for sustainable management of this palm trees forest.
