Agroecosystems: Building Resilience Through Soil, Water and Carbon Stewardship

Abstract

Agroecosystems function as complex socio-ecological systems in which interactions among soil, water, and carbon govern productivity, functional stability, and long-term sustainability. Increasing climate variability, accelerated soil degradation, and biodiversity decline have revealed the limitations of conventional intensification models, emphasizing the need for management strategies that strengthen agroecosystem resilience. In response, this chapter advances an integrated conceptual framework centered on the coordinated stewardship of soil, water, and carbon-three interdependent resources that regulate biogeochemical cycles, hydrological processes, and the ecological functioning of agricultural landscapes. At the European scale, recent assessments indicate that 27-35% of agricultural land is affected by one or two degradation processes, while 10-11% is simultaneously exposed to four or more stressors, underscoring the systemic nature of degradation and the need for integrated interventions. The chapter examines the principal dimensions of agroecosystem resilience, including biodiversity-driven functional redundancy, microbial regulation of soil processes, water-use efficiency, ecological pest management, and optimized biogeochemical cycling. Agroecological practices-such as conservation tillage, cover cropping, and organic amendments-significantly enhance soil properties, with documented increases in soil water content of up to 25%, microbial biomass carbon by 24%, and microbial biomass nitrogen by 40%. These improvements highlight the capacity of such practices to simultaneously support agricultural productivity and ecological stability. By integrating ecological principles with practical management, the chapter positions agroecosystem resilience as an emergent outcome of synergistic interactions among soil, water, and carbon, guiding the transition from short-term yield maximization toward long-term sustainability, climate mitigation, and enhanced adaptive capacity.
