CREATE TABLE table_name_10 (agri_culture_b VARCHAR(255), structural_poverty_g VARCHAR(255), income_poverty_f VARCHAR(255), mining_b VARCHAR(255))
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
