N4W's 6th Call for Proposals: Call for Ideas now closed
Thank you to everyone who submitted an idea to N4W's 6th Call for Proposals! The Call for Ideas period closed on October 16th, 2026, and our team is now reviewing all submissions.

Through this Call, we aim to partner with local champions seeking to ideate and develop Nature-based Solutions at landscape scale, to address water scarcity, flooding, and water quality issues. Selected applicants receive in-kind technical assistance from our N4W team to support program preparation and capacity-building.

What happens next?

All submissions are going through a Rapid Screening to identify the 20 most promising ideas. Shortlisted applicants will then be invited to submit a Detailed Proposal.

• Mid-November 2026: Shortlisted applicants receive an invitation to submit a Detailed Proposal.
• About 2½ weeks after the invitation: Detailed Proposal deadline.
• Mid-February 2027: Notification to successful applicants, followed by project scoping with the N4W team.

Due to the high number of submissions, we can only contact shortlisted applicants directly. We appreciate your patience during the review process.
