Without changes in consumption, along with sharp reductions in food waste and postharvest losses, agricultural production must grow to meet future food demands. The variety of concepts and policies relating to yield increases fail to integrate an important constituent of production and human nutritionbiodiversity. We develop an analytical framework to unpack this biodiversity-production mutualism (BPM), which bridges the research fields of ecology and agroeconomics and makes the trade-off between food security and protection of biodiversity explicit. By applying the framework, the incorporation of agroecological principles in global food systems are quantifiable, informed assessments of green total factor productivity (TFP) are supported, and possible lock-ins of the global food system through overintensification and associated biodiversity loss can be avoided.
Consequences of Increasing Food ProductionThe quest for greater crop output for food and non-food products [1-3] leads to both an increase in agricultural land use and an increase in yields, typically achieved through an intensification of cultivation methods that help to close yield gaps (see Glossary) [4,5,62]. This, in turn, leads to a loss of biodiversity in agricultural landscapes [7] and increases pressure on natural diversity [8], which continues declining despite ongoing efforts for protection [9]. The avoidance of food waste and dietary changes offer two demand-side options to reduce pressure on food production [10], but these have thus far not been achieved at the macro level [11].Biodiversity is a crucial component of ecosystem functions that are essential for agricultural production, such as soil fertility, pollination, and biocontrol (i.e., the control of plant pests by their natural enemies) [12][13][14][15]. This interdependence of biodiversity and agricultural production has led to a variety of concepts that aim to optimize the management of agricultural landscapes, balancing yields, biodiversity, and sustainability [16]. These concepts make use of agroecological principles [17], promote organic farming [18] suggest ecological intensification [19], or sustainable intensification (SI) [20], compare land sharing and land sparing concepts [21][22][23] and take the perspective of managing a coupled socioecological system (SES). While there is much published research on the SES concept, quantitative, empirically-based, and model-based implementations are largely lacking or their improvement through process-based validation is pending [24]. As a result, it is currently not possible to capture and quantify the biodiversity-production mutualism (BPM) in its entirety. However, recent research provides the necessary basis for such a comprehensive, quantitative, process-based understanding of the BPM concept [15,24,25].
