In the context of climate change, the ecosystems of protected areas are becoming increasingly important both for the preservation of biodiversity and for the livelihoods of local communities. Consequently, it is essential to examine the spatiotemporal dynamics of protected areas. This approach allows for the analysis and understanding of evolving phenomena by simultaneously integrating their spatial dimension and their variation over time, thus constituting an essential tool in geography. It also offers the possibility of representing and modeling trends as well as geographic structures at different temporal scales, thereby facilitating informed decision-making. The objective of this literature review is to provide an overview of the available scientific data on plant diversity and the trends in spatiotemporal dynamics associated with the nine nature reserves in Niger. Thus, this approach highlights the need to conduct retrospective and participatory studies for the sustainable management of these ecosystems in Niger.
Author Keywords: plant diversity, protected areas, spatiotemporal dynamics, biodiversity, sustainable ecosystem management.

Abstract: (french)
Dans un contexte de changement climatique, les écosystèmes des aires protégées acquièrent une importance majeure tant pour la préservation de la biodiversité que pour les moyens de subsistance des populations. Par conséquent, il devient indispensable d’examiner la dynamique spatio-temporelle des aires protégées. Cette approche permet d’analyser et de comprendre l’évolution des phénomènes en intégrant simultanément leur dimension spatiale et leur variation dans le temps, constituant ainsi un outil essentiel en géographie. Elle offre également la possibilité de représenter et de modéliser les tendances ainsi que les structures géographiques à différentes échelles temporelles, facilitant ainsi une prise de décision éclairée. L’objectif de cette synthèse bibliographique est de faire un état des lieux des données scientifiques disponibles sur la diversité végétale et les tendances de la dynamique spatio-temporelle associent aux neuf réserves naturelles du Niger. Ainsi cette approche montre la nécessité de réaliser des études rétrospectives et participatives pour la gestion durable de ces écosystèmes du Niger.
Author Keywords: diversité végétale, aires protégées, dynamique spatio-temporelle, biodiversité, gestion durable des écosystèmes.
