Ghana’s air fails to meet global health benchmarks, public health advocates say. The evidence is visible and routine: commuters report stinging eyes on congested corridors, dry coughs intensify during the harmattan season, and built-up neighbourhoods retain heat long into the evening. In response, the Nurture Nature Foundation (NNF) is advancing a direct, scalable remedy—“One House, One Tree”—that would require at least one tree to be planted and maintained at every home, school, office, estate, and shopfront, and embed that standard within national planning and permitting procedures.
Under the proposal, trees would be treated as essential infrastructure rather than ornamental features. Site plans submitted for approval would indicate species selection, setbacks, root-zone protection, and canopy spread; permits and completion certificates would be contingent on verified planting and basic watering provisions. NNF is urging households and private developers to act immediately, while calling on the Ministry of Works and Housing—working with allied agencies—to codify the requirement in building regulations and to apply heightened benchmarks to public projects, supported by periodic survival audits to ensure compliance and long-term maintenance.
Why this matters now
Trees are low-cost, high-impact infrastructure. They absorb harmful gases and particulate matter, reduce heat through shade and evapotranspiration, stabilize soil, buffer floods, and improve mental well-being. In dense settlements dominated by concrete and roofing sheets, a single well-placed tree can lower ambient temperatures, filter roadside dust, and create micro-habitats for birds and pollinators. Scaled nationally, One House, One Tree becomes a public-health intervention, a climate-adaptation tool, and a job creator in nurseries, landscaping, and long-term tree care.
Policy needed
Voluntary campaigns raise awareness; they do not restructure the systems that shape cities. To reverse declining air quality and climbing urban heat, Ghana must move from goodwill to governance—clear rules, measurable standards, and public accountability.
Update building codes and permit checklists.
Trees should be treated as essential urban infrastructure. NNF proposes a minimum green indexper parcel: at least one shade or fruit tree per dwelling, with larger estates meeting a per-unit tree ratio. Architectural submissions must include tree-placement drawings that show setbacks from walls, safe distances from utilities, likely canopy spread at maturity, and root-zone protection. Planning authorities should publish approved lists of indigenous, climate-resilient species by ecological zone, reducing guesswork, failed plantings, and maintenance burdens.
Tie compliance to the certificate of occupancy.
Rules matter only when verified. No project should receive a completion certificate until approved trees are planted and basic water stewardship is in place—mulch basins to retain moisture, simple roof-runoff harvesting into drums or swales, or routing appropriate greywater to tree pits. This moves landscaping from a decorative afterthought to a functional requirement that cools streets, filters dust, and shields public health.
Use incentives smartly.
Regulation sets a floor; incentives raise the ceiling. NNF recommends fast-track permitting and modest property-rate rebates for developments that exceed baseline standards with edible orchards, tree-lined corridors, or biodiverse clusters around schools and clinics. Districts can partner with women and youth groups to operate nurseries that supply bulk seedlings at subsidized rates—pairing environmental outcomes with local jobs in propagation, planting, and aftercare.
Mandate green in public procurement.
Government must lead. New public housing, schools, health centers, markets, and transport hubs should meet higher tree-shade benchmarks and publish survival audits at 6, 12, and 24 months. A public dashboard of trees planted, survival rates, and cooling hotspots addressed would reinforce accountability and improve outcomes year after year.
Plan from Day One
Urban planners and environmental advocates say tree integration should begin at concept stage, not after construction. Under the “One House, One Tree” approach, greenery is treated as core infrastructure—planned alongside water, power and drainage—to reduce heat, improve local air quality and enhance neighborhood livability.
For architects, the guidance is technical and specific. Building orientation should prioritise cross-ventilation, while trees should be positioned to perform defined functions: shading east–west walls, moderating temperatures over car parks, cooling pedestrian routes and filtering roadside dust. Designs are expected to anticipate canopy size and root behaviour at maturity to avoid conflicts with power lines, pavements, foundations and roof-drainage systems.
Developers are encouraged to translate site-level measures into district-scale networks. Plans should map continuous street-tree alignments on primary and secondary roads, locate pocket parks to disrupt heat islands and reserve space for shared orchards that double as community gathering points. The intent is to convert greenery from scattered ornament into connective infrastructure that links streets, homes and public facilities.
Workplaces and campuses are advised to blend ornamental, medicinal and edible species to lower cooling loads and support employee well-being. Properly sited shade can reduce daytime energy demand and expand the usability of outdoor areas for meetings and circulation.
For homeowners, officials recommend practical, low-maintenance selections and placements. A mango near the veranda supplies shade and fruit; moringa by the kitchen offers daily leaves; coconut or sea-almond along suitable boundaries provides breeze-friendly cover without structural risk. Basic measures—mulch rings, downpipe water-harvesting and seasonal pruning—can materially improve survival and performance. Advocates argue that when trees are planned with the same discipline as utilities, they receive appropriate siting, safety clearance and upkeep, delivering benefits over decades.
Restore the Coast
Nurture Nature is also calling for the rehabilitation of Ghana’s historic coastal green belt, once characterized by coconut groves and native vegetation that cooled settlements, stabilized dunes and protected roads and homes. They contend that restoration is simultaneously a climate-adaptation measure, a tourism strategy and a component of the blue economy.
District-level partnerships are proposed to replant climate-resilient coconuts and salt-tolerant native species in staggered age classes, maintaining continuity as older trees age out. The expected outcomes include cooler microclimates for residents and visitors, improved dune stability through deeper root systems and reduced glare and surface temperatures under expanded canopies.
Where sites meet recognised methodologies, stakeholders suggest linking restoration to credible carbon projects. Properly verified initiatives could generate carbon credits, creating a reinvestment loop to finance seedling supply, maintenance crews and livelihood diversification. Proponents stress the need for transparent governance to ensure that revenues support local communities and long-term stewardship.
In brackish zones, the programme would integrate mangrove and lagoon-edge restoration to filter water, blunt storm surges and provide nursery habitats that sustain local fisheries. Implementation would be guided by clear stewardship agreements, seasonal care schedules and site-specific species lists to keep costs predictable and outcomes consistent. Advocates say the result would be a cooler, more resilient and more visually appealing coastline with measurable economic benefits grounded in sustainable management.
Women and Youth
A greener Ghana must also be a fairer Ghana, and advocates say the transition will endure only if it creates dignified work and pathways to entrepreneurship—particularly for women and young people who are often first to feel climate and economic shocks. The proposed “tree economy” is designed to meet that test by embedding livelihoods across the value chain, from seed to product.
High-value tree crops. In ecologically suitable belts, agricultural planners recommend expanding cocoa and coffee under shade-tree systems that conserve soil moisture, moderate temperature extremes and rebuild on-farm biodiversity. Properly designed agroforestry layouts—combining canopy species with intercrops and living mulches—can balance food, fibre and income while buffering farms against rainfall variability and heat stress. Extension services would prioritise pruning calendars, grafting techniques, seedling spacing and soil-health practices, enabling smallholders to lift yields without degrading land.
Tech-enabled extension. To reduce the lag between research and practice, stakeholders propose a digital toolkit that includes drones for field scouting, pest and disease mapping, and shade-canopy assessments; mobile learning modules for quick dissemination of best practices; and remote advisory hotlines to triage outbreaks in real time. The approach is intended to lower the cost of knowledge, improve responsiveness during critical windows and make advanced agronomy accessible to women and youth who may lack legacy networks.
Post-harvest innovation. Value frequently leaks after harvest through spoilage and poor grading. The programme promotes solar or efficient biomass dryers to stabilise quality and reduce losses, alongside compact processing hubs capable of turning husks, pulp and pruningsinto inputs for cosmetics, beverages, bio-char and organic fertilisers. By closing loops and monetising by-products, these hubs help communities capture additional revenue while reducing waste and emissions—key steps in building a circular economy around trees.
Community nurseries. At the front end of the pipeline, the plan calls for contracting women and youth groups to operate nurseries that supply municipalities, developers and farmer co-ops with hardy, zone-appropriate seedlings. Nursery enterprises provide steady seasonal income, build local expertise in species selection and hardening, and ensure reliable supply during planting windows. Advocates argue that rooting environmental targets in livelihoods will make trees a backbone of shared prosperity, rather than symbols confined to photo opportunities.
Conclusion
Ghana now faces a practical choice: treat trees as essential infrastructure or continue absorbing the costs of dirty air and rising urban heat. The path forward is specific and shared. The Ministry of Works and Housing—working with allied agencies—should table and adopt “One House, One Tree” requirements within the current calendar year, embedding survival audits and zone-specific species lists into codes and permits. Architects and planners must integrate trees as functional design elements from the earliest sketches, specifying protection, watering and establishment protocols through to handover. Developers and landlords can set the market standard by committing publicly to a tree-per-unit ratio—or higher—paired with annual survival reports and clear remediation where plantings fail.
Execution belongs equally to local government and the private sector. District assemblies should budget for nurseries, community training and routine survival audits, while recognizing exemplary neighbourhoods and circulating lessons across districts. Businesses and philanthropic donors can accelerate scale by sponsoring district pilots, seedling drives, maintenance teams and stewardship training, with transparent reporting to keep outcomes credible and replicable. Households, finally, anchor the effort: plant what you can care for—start with one tree, then add another—using mulch, harvested rainwater and seasonal pruning to ensure survival.
The objectives are measurable and close at hand: cleaner air, cooler homes and streets, greener coasts and stronger local livelihoods. “One House, One Tree” is not a slogan but a work plan—delivered one plot, one street and one district at a time—until the country’s built environment and its living canopy stand in balance.
