Legend

(E) = Evidence-based | (A) = Assumption needing validation

The diagram groups deeper causes so the full tree stays readable.

Youth Example Breakdown

Effects: Income insecurity (E), migration (E), social tension (A), lost economic potential (A), inequality (E).
Core Problem: Young adults aged 18-25 in rural communities have limited access to decent, stable employment and livelihood opportunities.
Root Causes: Skills mismatch (E), infrastructure barriers (A), weak enterprise ecosystem (A), social and cultural factors (A).

Stakeholder Validation Questions

Economic challenge: How would you describe the biggest economic challenges facing young people in this area?
Root causes: What are the main reasons young people struggle to find good work here?
Skills mismatch: What skills do local employers need compared with what young people have?
Barriers: What makes it difficult for young people to start businesses or find employment?
Local assets: What supports work well for young people, and what's missing?

Example 2: Maternal Health

Context: Rural maternal health outcomes in South Asia
Core Problem: Pregnant women in rural areas experience high rates of pregnancy-related complications and maternal mortality.
Causes: Limited antenatal care (E), cultural barriers to care (A), health system weaknesses (E).
Effects: Preventable maternal deaths (E), economic burden on families (A).

Example 3: Education Quality

Context: Primary school learning outcomes in Sub-Saharan Africa
Core Problem: Primary school students in rural communities have low literacy and numeracy proficiency by Grade 3.
Causes: Teacher capacity gaps (E), learning environment challenges (A), home-school disconnect (A).
Effects: Grade repetition and dropout (E), reduced lifetime earning potential (A).

Example 4: Environmental Conservation

Context: Community forest management in Southeast Asia
Core Problem: Forest resources in community-managed areas are declining due to unsustainable harvesting and land conversion.
Causes: Economic pressures (E), weak governance (A), knowledge gaps (A).
Effects: Biodiversity loss (E), reduced climate resilience (A).

Notice the Pattern

Across sectors, the structure repeats: a specific core problem, multi-level causes, time-horizon effects, and (E/A) tagging.

Key Takeaways Across Examples

Specificity: Population, geography, and issue are stated clearly.
Multi-dimensional causes: Economic, social, cultural, and policy factors appear together.
Depth: Direct, underlying, and structural causes are separated.
Evidence tags: (E/A) tagging stays visible throughout.
Time horizons: Effects include immediate, medium-term, and long-term consequences.
