I can imagine that the query should be something like this. But my SQL is not very good.

SELECT
  p.product_id as product_id,
  p.name as name,
  o.quantity as quantity
FROM
  product p
  JOIN (
    SELECT
      product_id,
      SUM(quantity) as quantity
    FROM
      order
    WHERE
      dispatch_date > DATEADD(year, -1, GETDATE())
    GROUP BY
      product_id
  ) o ON o.product_id = p.product_id
WHERE
  p.available_from < DATEADD(month, -1, GETDATE())
  AND o.quantity < 10
