Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_6463 ( "District" text, "2010 Population (000)" real, "2008 GDP (USD bn) a" real, "2008 GDP per capita (USD) a" real, "Agri culture b" real, "Mining b" real, "Manufac turing b" real, "Services & cons truction b" real, "Exports (USD mn) 2011" text, "Median mo. salary (USD) a e" real, "Vehicles (per 1000) d" real, "Income poverty f" real, "Structural poverty g" real )

### 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?

### Accurate SQL ###

SELECT COUNT("Agri culture b") FROM table_6463 WHERE "Income poverty f" < '13.6' AND "Mining b" = '1' AND "Structural poverty g" < '7.8'
