CREATE TABLE table_34952 ("Region/country" TEXT, "1985-1990" FLOAT, "1990-1995" FLOAT, "1995-2000" FLOAT, "2000-2005" FLOAT)

When 2000-2005 is smaller than 2.52, and 1990-1995 is less than 0.37, what's the total of 1995-2000?
SELECT SUM("1995-2000") FROM table_34952 WHERE "2000-2005" < '2.52' AND "1990-1995" < '0.37'
SELECT SUM("1995-2000") FROM "table_34952" WHERE "1990-1995" < '0.37' AND "2000-2005" < '2.52'
