How to reconcile short-term and long-term objectives in mixed farms? A dynamic model application to mixed fruit tree - vegetable systems

چکیده
Mixed fruit tree and vegetable (MFV) farms correspond to the joint production of trees crops. In temperate regions, this emerging farming system is a potentially attractive land use foster diversification agricultural systems. However, these systems combine two productive labor-intensive enterprises (orchard market gardening) in practice, feasibility depends on availability need for labor. Long-term yield predictions are needed assess economic profitability such innovative A dynamic bio-economic model MFV was developed its main properties over time. This simple state-control based yields, biological dynamics, workload requirements each enterprise. Due lack data from long-term experiments, parametrized specialized calibrated with expert knowledge. The implementation made it possible simulate management strategies crops trees, their impact dynamics. Results show that gardening enterprise has an overall higher per hectare than trees. Nevertheless, mixed composed roughly equivalent shares make decrease constraints while maintaining high level profitability. addition, intermediate can lead long term, but require addressing both short- objectives, ability farmers cope several consecutive years lower income. Further research now better understand processes underlying evolution different configurations.

For the commercial success of advanced therapies including CAR-T, they must not only be safe and effective, but also consistently produced and delivered to patients at a cost substantially less than the reimbursable rate. Regardless of whether your therapy is allogeneic or autologous, initial protocols are usually developed using laboratory equipment and skilled research staff completing asepti...

Disturbance by military maneuvers over short and long time scales may have differential effects on grassland communities. We assessed small mammals as indicators of disturbance by military maneuvers in a mixed prairie in southern Oklahoma USA. We examined sites on two soil series, Foard and Lawton, across a gradient of disturbance intensity. A MANOVA showed that abundance of small mammals was a...
