Senegal municipality budget transparency: a democratic imperative in 2026
Open Budget Index (OBI) 2023 ranked Senegal at 50/100 for national budget transparency — above sub-Saharan Africa average (35) but far from Top 10 (South Africa 87, Georgia 86, Sweden 89). At municipal level: it's worse. OBI Senegal 2024 audit evaluated 32 communes: average score 18/100. Most publish their budget in unreadable PDF, without budgeted vs realized comparison, without project detail.
Yet article 25 of the General Code of Local Authorities (law 2013-10 amended 2023) requires communes to publish their annual budget and administrative account. And law 2023-08 on decentralization reinforces transparency obligations (council minutes publication, expenses > 5 M FCFA, etc.).
An open budget portal is more than a legal obligation. It's a governance tool that makes visible where taxpayer money goes and defuses 70% of mismanagement suspicions. In Pikine, open budget deployment in 2024 raised citizen trust (Afrobarometer Senegal survey) from 31% to 52% in 18 months.
H2: Anatomy of a modern open budget portal
Homepage. Key figures: total year N budget, main revenue (3-5 categories), main expenses (5-7 categories), N vs N-1 variation. Everything on one mobile-readable page.
Sankey revenue / expense visualization. Diagram showing where money comes from (FECL, state transfers, local taxes, TOM, business licenses) and where it goes (operations, investment, salaries, public lighting, roads, schools, health). Recommended libraries: D3.js or Plotly. Development cost: 850 KFCFA-2.5 M FCFA.
Budgeted vs realized comparison. Line-by-line table: planned (finance law), committed (order placed), mandated (payment triggered), paid. Colors: green if realization > 90%, orange if 60-90%, red if < 60%. Quarterly updates.
Detail per investment project. For each project > 25 M FCFA: description, budget, status (study / procurement / works / delivered), prime contractor, schedule, photos. Pikine: 47 projects tracked this way in 2025.
Related public procurement. Link to commune ARMP markets, awardees, amounts, attribution type (open call, restricted, direct).
Citizen space. Moderated comments under each section, questions to DG, problem reports (broken streetlight, damaged road — pairable with FixMyStreet open source).
Downloads. Primary budget PDF, administrative account PDF, raw CSV / JSON data (open data, cf article 5 of this batch).
H2: Recommended technical stack
Frontend. Next.js 14 + Tailwind + D3.js / Plotly for charts. SSR for SEO, ISR for automatic quarterly updates.
Backend. Node.js API (Express or Fastify) or Python (FastAPI). PostgreSQL database for structured financial data. Source of truth: commune accounting ERP (often SIM_BA, Bourse Africaine, or rigorous Excel spreadsheets). Airbyte or n8n ETL connector to sync quarterly.
Hosting. Sonatel Cloud or Sénégal Cloud, 2-4 vCPU, 8-16 GB RAM. Cost: 480 KFCFA-1.2 M FCFA / year.
Open source reference. OpenBudget.io (used by several European cities), OpenSpending (CKAN), BOOST (World Bank, used by more than 40 countries). Adaptable to Senegalese context with a few weeks of dev.
H2: 6-month deployment methodology
Month 1 — Scoping. Existing audit (budget publications, accounting process, file formats). Workshop with DG, accountant, elected official in charge of finances. Perimeter definition (how many retroactive years? what granularity?).
Month 2 — Data architecture. Data model: budget exercise, chapter, article, line, project, supplier, market. Mapping to commune accounting plan (M14 adapted Senegal). Taxonomy definition.
Months 3-4 — Dev + integration. Portal development + quarterly ETL + 3-year history ingestion. Data quality tests (consistency revenue = expenses + balance).

H2: Civic KPIs and measurable impact
- Local OBI score (target: from 18 to 60+ in 18 months)
- Unique portal visitors / month (target: 1-3% of population)
- Citizen comments / quarter (target: 50-300 per publication)
- Citizen trust (annual survey, target +15 points)
- Administrative account publication delay (target: 3 months max after exercise close, vs 9-18 months currently)
FAQ
Which data not to publish?
Nominative beneficiary data of social aid (GDPR / Senegal data protection law). Individual salary details (publish grid, not individuals). Information on ongoing markets before attribution (competition). Everything else: by default, publish.
What optimal granularity?
Too fine = noise, opacity by information excess. Too broad = no value. Optimal level for general public: 5-7 main chapters + project detail > 25 M FCFA + markets > 5 M FCFA. For associations / journalists: downloadable raw CSV data.
How to handle "trick questions" in comments?
Published moderation charter. Systematic response in 7 working days by deputy DG or finance elected official. Factual tone, never polemic. If question reveals real error: publicly acknowledge, correct, explain. If false question: respond with sources, without aggression.
Should you do open budget if commune is very poor?
Yes especially. A commune with small budget (< 500 M FCFA / year) often has fewer qualified staff, less external control, hence more mismanagement risk (or suspicion). Open budget reinforces city hall legitimacy with partners (FECL, coop agencies, NGOs). Several donors (UNICEF, World Bank) now finance portal cost for eligible communes.
What role for civil society?
Crucial. Associations like OSIWA, Forum Civil, CONGAD do budget analysis and publish annual "budget watch". Invite them to portal editorial committee. Co-build visualizations with them. First ROI: media trust in portal (not perceived as city hall propaganda tool).
