Systemic intervention to tackle the constraints and challenges facing stakeholders and the performance of the agricultural sector in Ghana

Constraints and challenges in Ghana´s agricultural industry limit its throughput. A policy constraint is an issue when it comes to agricultural sustainability. A fresh approach to interventions and capacity-building using systems thinking approach; the four levels of thinking and the Evolutionary Learning Laboratory during a stakeholder workshop in Ghana has shown remarkable impact on the ability of the agricultural industry to evolve, improve, and raise its efficacy. With stakeholder´s interventions, the Bayesian belief network (BBN) models indicated that, agricultural productivity level will rise from 57.5 to 92.2% reducing poverty level from 44.9 to 10.0% below the poverty line. Also farmers yield and profit increased. The BBN revealed the impact of uncertainty on management systems to be accounted for in the decision making process. This means that decision makers can balance the desirability of an outcome against the chance that the management option selected may fail to achieve it.
