Urban garden production possibility curve

This production possibility curve shows the trade-off facing Riverside Garden. With fixed plots, water and volunteer hours, the garden can grow more vegetable beds only by giving up some herb beds. The bowed frontier represents efficient combinations: the garden uses its resources fully at every point on it. The current plan is on the frontier, while the unused-plots point sits inside it and signals capacity that has not been put to work. Use a curve like this to discuss scarcity, opportunity cost and productive efficiency before choosing a seasonal planting plan. It gives teams a concrete starting point for reviewing assumptions, data quality and next steps together.
