Biotechnology for resilience in the urban-rural gradient

Abstract

The urban-rural gradient constitutes a continuous and dynamic socioecological system, in which natural, productive, and urban processes are closely intertwined, generating direct effects on human health, food security, and biodiversity. The pressures arising from urbanization, agricultural intensification, and climate change highlight the need for integrated approaches that strengthen territorial resilience without fragmenting their social and environmental components. In this context, biotechnology emerged as a strategic tool capable of articulating differentiated solutions along the gradient, provided that it is applied from an ethical, participatory, and systemic perspective. Its potential lies not only in technological innovation but also in its capacity to integrate local knowledge and respond to the specific needs of each context, from densely populated urban areas to rural and peri-urban landscapes. The applications analyzed—including generative traditional regenerative production systems, resilient agricultural practices, local bioinputs, and genetic and ecological conservation strategies—demonstrate that biotechnology can simultaneously strengthen food security, environmental health, and livelihood stability. These experiences show that there is no single solution, but rather a set of adaptable tools that enable context-specific responses aligned with the social and ecological diversity of the urban-rural gradient. In this way, biotechnology, conceived as a bridge between scientific innovation and community knowledge, is consolidated as a key for promoting more just, functional, and regenerative territories capable of sustaining human well-being without compromising the integrity of the ecosystems that support them
