Challenge Win - An interactive geospatial dashboard for analyzing land degradation in the Assaba region of Mauritania and the broader Sahel — built at StartHack 2025. # Addax 🌍 > An interactive geospatial dashboard for analyzing land degradation in the Assaba region of Mauritania and the broader Sahel — built at StartHack 2025. **🎬 Watch the Demo** · **📊 View the Presentation** --- ## 🏆 Award We won the **UNCCD G20 Global Land Initiative Challenge** at StartHack 2025! View the announcement on LinkedIn → ## The Problem The Sahel region is facing severe land degradation driven by a combination of climate stress and human pressures — erratic rainfall, population growth (~3% annually), overgrazing, deforestation, and unsustainable farming. In Mauritania's Assaba region, virtually all natural forest has disappeared due to decades of fuelwood cutting and agricultural expansion. Understanding these trends requires synthesizing diverse datasets (population, vegetation, precipitation, land cover) across time and geography — a task poorly suited to static reports. ## Solution Addax is an interactive web dashboard that lets researchers, policymakers, and NGOs explore two decades of environmental and demographic data across the Assaba region at the district and municipality level. It combines time-series visualizations, geospatial heatmaps, and an AI-powered chatbot that surfaces key findings on demand. --- ## Features **Population Over Time** — heatmap showing population density across districts from 2010–2020, with a time slider and total population trend chart. **Precipitation Over Time** — district-level precipitation data visualized geospatially and over time, revealing rainfall variability patterns. **GPP Over Time** — Gross Primary Production (a proxy for vegetation health) tracked at district level from 2010–2023, exposing degradation hotspots. **Land Cover Map** — spatial visualization of land cover changes across the region. **Municipality Comparison** — side-by-side comparison of any two municipalities across precipitation, GPP, or population metrics. **Dashboard Chatbot** — an AI assistant integrated directly int …
