Problem Tree is a diagram or model used to visualize and solve a problem by breaking it down into smaller, more manageable sub-problems. Here is a sample for the cause analysis of dust bowl. The diagram starts with the main problem at the root and branches into smaller problems, such as economic recession, climate changes and poor farming practices. This Problem Tree helps to structure thinking and provides a visual representation of the problem-solving process in handling natural disasters. This type of diagram is commonly used in problem-based learning, decision-making, and systems analysis.
