Abstract
The study aims to assess how SNAT, its implementation mechanisms, the Territorial Planning Programs (PATs), and SNAT Dashboard, contribute to reducing regional disparities and preparing Algeria's landscape for future environmental and economic challenges. The research methodology includes a qualitative examination of government planning documents and spatial policy frameworks. Results suggest that while SNAT provides a comprehensive structure, its effectiveness in enhancing shadow regions largely relies on improved coordination among sectors and successful implementation at the local level. The study recommends bolstering multi-level governance, establishing strong monitoring and evaluation systems, and incorporating knowledge-driven strategies for sustainable, competitive, and balanced territorial development. Ultimately, revitalizing shadow areas is crucial for SNAT to realize comprehensive national development and integration in Algeria.
