The specific problem we are addressing is the adverse impact of extreme heat on building performance, indoor living conditions, and the well-being of residents in densely populated urban areas. Extreme heatwaves and the urban heat island (UHI) phenomenon have been shown to significantly increase internal temperatures in buildings, leading to discomfort, disrupted sleep, and increased energy demands for cooling. This situation is exacerbated by global warming, which directly affects densely populated urban areas like Ward no. 18 under Khulna Metropolitan city.
In Ward no. 18, with a population of approximately 52,000, the effects of extreme heat are particularly pronounced due to the lack of green spaces, disappearing trees, and the prevalent use of air-conditioners and air coolers, contributing to increased carbon emissions. Unused rooftops in the community absorb extreme heat, further elevating indoor temperatures. This environmental vulnerability is compounded by household waste management issues, as kitchen garbage often remains unused and contributes to local environmental degradation.
The scale of this problem is significant both locally and globally. In Khulna and similar urban areas worldwide, thousands of people are affected by the adverse effects of extreme heat on building and infrastructure performance, as well as on their health and well-being. Globally, urban areas are experiencing increasing temperatures due to climate change, leading to a rise in heat-related illnesses, higher energy consumption for cooling, and greater strain on infrastructure.
Several factors contribute to this problem, including urbanization, deforestation, and the lack of sustainable building and waste management practices. Our solution aims to address these factors by introducing eco-friendly rooftop initiatives and promoting sustainable practices at the household level.
Our proposed solution includes the development of eco-friendly rooftop technologies and activities to reduce heat absorption, enhance building performance, and provide residents with a space for fresh organic gardening. By utilizing unused rooftops for eco-friendly initiatives, we can mitigate the effects of extreme heat, reduce energy consumption, and create green spaces that contribute to improved air quality and community well-being.
Additionally, we plan to implement household waste management programs that encourage recycling and composting, turning kitchen garbage into valuable resources for organic gardening on rooftops. This approach not only addresses environmental vulnerabilities but also provides residents with access to fresh, organic fruits and vegetables, contributing to improved nutrition and overall health.
In conclusion, our solution aims to tackle the pressing issue of extreme heat and its adverse effects on building performance, indoor living conditions, and community well-being in Ward no. 18 and similar urban areas. By leveraging unused rooftops for eco-friendly initiatives and promoting sustainable household practices, we can create resilient, healthy, and vibrant communities that are better equipped to adapt to the challenges of climate change.
Our solution is a community-driven, household-based aerobic composting method using barrel compost production to transform kitchen garbage into valuable compost for rooftop farming in 20 high-rise buildings in Ward no. 18 under Khulna Metropolitan city, Khulna.
Here's how it works:
1. Barrel Compost Production: Each of the 20 buildings will have a pair of barrels placed on their rooftops to collect kitchen garbage from 8-20 families. These barrels will be used to produce compost through an aerobic composting process. Aerobic composting involves using oxygen to break down organic waste, creating a nutrient-rich compost that is ideal for gardening.
2. Rooftop Farming: The compost produced from the barrels will be used for rooftop farming on each building. Building owners and residents will have the opportunity to cultivate a variety of fruits and vegetables on their rooftops using this compost.
3. Community Engagement: Building owners and residents will actively participate in the project by using the compost for rooftop farming. They will also consume the harvested fruits and vegetables, promoting local food production and consumption.
4. Compost, fruits and vegetables Sales: Any excess compost, fruits and vegetables produced beyond the needs of the building owners will be sold through the RUSTIC sell center. This not only generates income but also promotes the use of compost in other gardening and farming activities.
5. Training and Support: An agriculturist from RUSTIC will organize and facilitate training sessions for building owners and residents on aerobic composting, rooftop farming techniques, and organic gardening practices. This will empower them with the knowledge and skills needed to successfully manage their rooftop farms.
6. Project Duration and Sustainability: The project will span 24 months, during which RUSTIC will provide necessary assistance and support. After the project concludes, stakeholders and RUSTIC will continue to collaborate, ensuring the sustainability of the rooftop farming initiatives and compost production.
In simple terms, our solution involves setting up composting barrels on rooftops to turn kitchen garbage into compost. This compost is then used for rooftop farming, allowing building residents to grow their own fruits and vegetables. Any extra compost is sold, and the harvested produce is consumed by the residents or sold/shared among stakeholders. Training and support are provided throughout the project to ensure its success and sustainability. By implementing this solution, we aim to promote sustainable waste management, local food production, and community engagement in Ward no. 18, Khulna.

Over the past 15 months, RUSTIC has made significant progress in implementing our pilot project, starting with two buildings and a total of 78 beneficiaries from 12 families. Our team worked diligently to mobilize and engage family members, sharing the concept and ensuring their active participation.
To begin, we conducted a thorough feasibility survey in collaboration with a civil engineer, focusing on the rooftop's weight load and structural integrity. By closely working with our agriculturist, we guided and assisted families in preparing barrel compost and setting up their rooftop farms. We allocated two separate shaded areas using nets (known as "Ghuri" or "Macha" in Bengali) to protect the plants from extreme weather conditions.
The roof space available for cultivation consisted of two areas, one measuring 1800 square feet and the other 2200 square feet. Our technical officer conducted training sessions for household members from both buildings, educating them on the collection of kitchen waste for compost production. Simultaneously, our agriculturist provided training on soil preparation, watering techniques, and compost application.
To ensure optimal growth and minimize water usage, we encouraged the use of kitchen water for irrigation, strictly avoiding the use of any detergent or chemically contaminated water. In total, we prepared 44 half barrels, filling them with the appropriate soil mixture and compost. Various vegetable seedlings, including Cabbage, Cauliflower, Green peas, Bottle gourd, Spinach, Bean, Eggplant, and Chili pepper, etc. were planted in these barrels.
After three months of diligent nurturing, we successfully harvested a substantial amount of vegetables from the rooftop gardens, amounting to an average of 120 kilograms per month. Additionally, we produced a remarkable six metric tons of compost, utilizing four metric tons within the rooftop gardens themselves. The remaining two metric tons were even sold within the community, contributing to its sustainability.
Throughout this pilot initiative, the family members directly involved in the project have gained significant benefits. Beyond the tangible outcomes of bountiful harvests and compost production, the rooftops themselves have been transformed into controlled and protected spaces, shielded from extreme heat by the presence of the rooftop gardens.
As we reflect upon our accomplishments thus far, we are encouraged by the tangible positive impact we have made on the lives of our beneficiaries. These achievements inspire us to continue expanding our efforts and implementing our sustainable rooftop gardening model to benefit even more families in the future.
