Project Profile of Rooftop Gardening and Organic Vegetable Production in Bangladesh
1. Executive Summary
The most important opportunity lies in transforming under-utilised rooftop spaces into organic vegetable production zones in Bangladesh, especially in urban centres. Urban rooftops are abundant in cities such as Dhaka and Chittagong. With rising demand for chemical-free produce, rooftop gardens offer both environmental and economic benefits. For example, urban studies in Dhaka show rooftop gardening to have a benefit-cost ratio (BCR) of about 1.32. Bangla Jol+2Bangla Jol+2
Therefore this project profile outlines required inputs, cost estimates in Bangladeshi Taka (BDT), market outlook, production plan and risk mitigation to create a bankable model.
2. Market & Demand Overview
The most important driver is consumer preference for fresh, organic vegetables. According to a study, city-dwellers in Dhaka are increasingly turning to rooftop gardening to avoid contaminated and adulterated food. Dhaka Tribune
Moreover, rooftop farming can contribute meaningfully: one article argues that rooftop gardening could meet about 10 % of Dhaka’s vegetable demand if large rooftop areas are utilised. The Financial Express
Besides direct food production, rooftop gardens improve urban micro-climate, help reduce heat islands, improve air quality and reduce building energy usage. MDPI+1
Given these factors, an urban rooftop organic vegetable production business in Bangladesh has a strong market base.
3. Project Scope & Objectives
Scope: Convert a rooftop of approximately 1,000 sq ft (≈ 93 m²) into an organic vegetable production system. Grow seasonal and high-demand vegetables such as tomatoes, brinjal, chilli-pepper, spinach, and gourds, using organic inputs and minimal chemical fertiliser/pesticide.
Objectives:
-
Produce enough vegetables to serve ~4-6 households or supply to local market/retail.
-
Demonstrate a viable investment model with >1.3 benefit-cost ratio and net positive returns within 1–2 years.
-
Promote urban greening, environmental benefits, and food security.
-
Scaleable to multiple rooftops or small commercial setups in urban areas.
4. Project Inputs & Cost Estimate
The most important cost categories include infrastructure, soil & containers, seeds/seedlings, organic inputs, labour and irrigation. Based on local studies, setting up might cost around Tk 25,000–30,000 for a small rooftop garden in Bangladesh. The Independent BD+1
Below is a sample cost estimate for a 1,000 sq ft setup (≈93 m²). All figures in BDT.
| Item | Estimated Cost (BDT) | Notes |
|---|---|---|
| Roof preparation (structural check, waterproofing) | 15,000 | Ensure safety and load capacity |
| Containers, raised beds, polybags | 8,000 | Recycled drums, bags |
| Soil mix, compost, organic manure | 7,000 | Coco peat/sand/compost ratio as per guidelines IJPRSE |
| Seeds / seedlings (seasonal vegetables) | 3,000 | First cycle planting |
| Irrigation setup (hose, drip, rainwater capture) | 4,000 | Efficient water use |
| Miscellaneous garden tools & accessories | 2,000 | Hoe, sprayer, stakes, etc |
| Labour / initial maintenance (3 months) | 6,000 | Part-time help if needed |
| Total Setup Cost | 45,000 | Approximate for 1,000 sq ft |
Annual Operating Cost (Year 1)
Includes seeds, compost top-up, small repairs, labour, water. Estimate: BDT 15,000.
Annual Revenue Estimation
Using a conservative yield for rooftop vegetable production: According to data in Dhaka, yield for rooftop gardens for certain crops may be ~11.9 kg tomato per roof garden per year. New Age+1
Assume mixed cropping results in revenue of BDT 80,000 in first year (at average market price BDT 40/kg across varied veg).
Thus approximate net return = Revenue 80,000 – (Setup amortised over 5 years ~9,000 + operating cost 15,000) = ~56,000 in Year 1.
Benefit–Cost Ratio (BCR)
Revenue / Total cost ≈ 80,000 / (45,000 +15,000) = ~1.33 – aligns with published BCR of 1.32. Bangla Jol+1
5. Production Plan
Crop Selection & Calendar
Select vegetables suited to rooftop and local climate: tomato, brinjal, chilli, bush bean, spinach, gourd. Studies in Dhaka show top crops include tomato (61.6% of rooftop gardens), brinjal (61%), Indian spinach (47.8%) etc. Dhaka Tribune+1
Plan two seasons per year: Rabi season (Oct–Mar) and Kharif season (Apr–Sep).
Planting Area & Layout
-
Use raised beds or containers across the 93 m² area.
-
Allocate ~60% area for fruiting vegetables (tomato, brinjal, chilli) and ~40% for leafy greens and gourds.
Organic Practices
-
Use compost from kitchen waste, properly matured, to reduce fertiliser cost. Scribd
-
Use drip irrigation or water-efficient systems; capture rainwater where possible.
-
Avoid synthetic pesticides; use neem oil, trap crops, companion planting.
Harvesting & Sales
-
Harvest weekly / bi-weekly cycles for greens; every 6–8 weeks for fruiting crops.
-
Sell to local households, neighbourhood markets, cafes or co-opt with community-supported agriculture (CSA) model.
-
Keep track of yield and costs for continuous improvement.
6. Marketing & Revenue Strategy
The most important revenue streams:
-
Direct retail: supply fresh produce to local customers at premium for organic.
-
School / office cafeteria supply: pitch rooftop produced “urban-organic” branding.
-
Value-added: small packages of herbs, salad greens, micro-greens.
Estimated revenue breakdown for first year: -
Vegetables sales: BDT 70,000
-
Herbs/micro-greens premium: BDT 10,000
Total revenue ~ BDT 80,000 (as earlier assumed).
Expand in subsequent years by increasing area, improving varieties or adding vertical planting.
7. Financial Projections (5-Year Horizon)
