Five steps from a problem to its solution.

Help me design and build a first working prototype for this problem in West Khasi Hills, Meghalaya, India.

Problem: Villagers along the Kulsi River on the Assam–Meghalaya border can't see what the proposed dam would mean for their own village.
Who it hurts: Bodo, Garo, Khasi and Rabha villagers in West Khasi Hills (Meghalaya) and Kamrup (Assam) who live near the proposed Kulsi dam site.
The moment it hurts: Hearing that a 62-metre dam is planned upstream or downstream, without knowing whether their land, fields or homes fall in the area it would affect.
What people do today: Villagers rely on rallies, a joint protection committee and their traditional chiefs, while the project's details sit in a detailed project report costed at 2017 prices.
Why it is still unsolved: The project spans two States and a disputed boundary, its documents are technical and not shared village by village, and villagers want local communities and traditional institutions consulted before the project goes ahead.
What solved looks like: A public, plain-language page for the Kulsi project with a map of the dam site, the area it would submerge or irrigate and the 46 villages named as affected, the key figures from the project report, and a record of every consultation and consent required, in Khasi, Garo, Bodo, Assamese and English.

First, list what you would need to learn from the people affected before building, as interview questions.
Then propose the simplest version that would help, the screens or messages it needs, and the data it would use.
Keep it cheap to run, accessible, and respectful of people's privacy. Flag anything you are unsure about instead of guessing.
