Perhaps you should try some spelling variations:
states transport » systems transport, water transport, safe transport
transfer risks » transfer risk
net transfer » net transfers, heat transfer, money transfer
risks across » risk across, costs across, firms across
small states » small scale
agua 1 » agua e, agua 2, agua _
1 net » 16 net, _ net, 1 new

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( agua 1 net transfer risks across ) OR ( agua small states transport _ co ))~.
• Adding a wildcard symbol may retrieve word variants: (( agua 1 net transfer risks across ) or ( agua small states transport _ co ))*.
