The document discusses the complex relationship between agriculture and health in Sri Lanka. It notes that most poor people depend on agriculture for their livelihood and income for health services. Certain types of agricultural programs in Sri Lanka have been more successful at achieving food security and nutrition goals, such as expanding cash crop production and access to credit. However, increased income alone does not ensure better nutrition, which depends on other factors like food expenditures, distribution within families, and health/hygiene. The key is better integrating health and agriculture interventions and policies to address issues like diseases linked to irrigation projects.
