Integrating Indigenous and Scientific Soil Knowledge for Climate-Resilient Environmental Management in Smallholder Agriculture

Abstract

Climate change is placing increasing strain on smallholder agricultural systems, as described in recent literature, particularly in semi-arid areas with land degradation, soil decline, and climate variability. In these settings, land serves as a critical juncture linking environmental processes, agricultural production, and human decision-making. Although scientific land-use and soil-management approaches rely on measurable, scalable solutions, they often lack consideration of local variations and socio-economic factors. Whereas indigenous knowledge based on land knowledge offers contextual and experiential perspectives yet is rarely incorporated into formal adaptation models. This research uses a conceptual integrative approach by integrating and meshing indigenous knowledge with science for soil and land management for climate adaptation. By studying knowledge systems across various agroecological systems, the study explores areas of overlap and difference between these approaches. These findings highlight the complementary importance of indigenous and scientific perspectives in explaining soil processes. Indicators discovered within indigenous practices, including soil color, plant composition, and biotic activity, map onto scientific indicators such as soil organic carbon, nutrient status, and physical properties. However, the convergence of these knowledge systems is hampered by bureaucratic, policy, and implementation barriers. To overcome such barriers, this study presents the co-created land-based adaptation framework under three domains: indicator integration, practice integration, and scale integration. This framework provides an interpretable, realistic process for integrating traditional and modern indigenous forms of knowledge to improve land and soil management practices in times of climate change. The framework's focus on linking local relevance with scientific rigor aims to develop climate-resilient, context-sensitive, and inclusive agricultural systems.
