Perhaps you should try some spelling variations:
integration efforts » international efforts, conservation efforts
irrigation schemes » irrigation scheme, irrigation systems
asian integration » urban integration, american integration, spatial integration
supply scale » supply case, supply scheme, supply social
supply asian » supply asia, supply design, supply ann

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( supply scale irrigation schemes. ) OR ( supply asian integration efforts. ))~".
• Adding a wildcard symbol may retrieve word variants: (( supply scale irrigation schemes. ) OR ( supply asian integration efforts. ))*.
