Table schema:
CREATE TABLE table_name_10 (agri_culture_b VARCHAR, structural_poverty_g VARCHAR, income_poverty_f VARCHAR, mining_b VARCHAR)

Question: Income poverty f smaller than 13.6, and a Mining b of 1, and a Structural poverty g smaller than 7.8, so what is the total number of agriculture?
SQL: SELECT COUNT(agri_culture_b) FROM table_name_10 WHERE income_poverty_f < 13.6 AND mining_b = 1 AND structural_poverty_g < 7.8
