The future of production systems in a globalized world

Abstract

Human life is ultimately dependent on ecosystem services supplied by the biosphere. These include food, disease regulation, and recreational opportunities. Over the past 50 years, humans have changed ecosystems more rapidly and extensively than at any other time in human history, primarily to meet our growing demands for provisioning ecosystem services (eg food, freshwater, and timber). These changes have impacted other ecosystem services (eg climate regulation and erosion control). Current demand for ecosystem services is growing rapidly. How these demands are met will play a major role in determining the ecological, economic, and cultural future of the planet. While much is known about improving management of production systems to be more sustainable, research gaps remain. Challenges for ecologists include understanding the connection between management regimes, ecosystem structures and provision of multiple types of ecosystem services, understanding interactions among ecosystem services, and exploring the role of thresholds and resilience in production systems. Understanding these systems and how to manage them to ensure resilient provision of multiple ecosystem services is a key challenge for ecology. © The Ecological Society of America.
