Murang’a: A Murang’a-based non-governmental organization, Women in Climate Change Organization (WICCO), has urged residents to adopt vertical gardening and water harvesting techniques as sustainable ways to improve food production and protect the environment. Speaking in Githama Village of Kandara Sub County during a community training session, WICCO chairperson Diana Muthoni emphasized the importance of agroecology in addressing food insecurity, shrinking land sizes, and climate-related challenges.
According to Kenya News Agency, Muthoni outlined how agroecology can protect soils and reduce reliance on conventional agricultural chemicals, thereby building resilient communities. She highlighted that vertical gardens, water harvesting, and soil-friendly practices can help households secure food, improve nutrition, and conserve the environment. Vertical gardening, in particular, was championed as an innovative and productive method of growing food in cone-shaped gardens, made from durable HDP polythene.
These vertical gardens can accommodate between 80 and 120 seedlings, with some models supporting up to 150 plants of spinach and kales. Muthoni explained that a well-established cone garden could last up to 15 years, offering an economical and sustainable solution for families with limited land space. By utilizing kitchen gardens, families can reduce the need to purchase vegetables frequently, as these gardens require minimal space and water.
Water harvesting is another major innovation promoted by WICCO, especially as climate change affects rainfall reliability in the region. Muthoni stated that training residents on harvesting water during the rainy season can ensure sufficient supplies during dry months, thereby improving family nutrition.
During a practical demonstration, agronomist Lawrence Njuguna emphasized the efficiency and nutritional benefits of vertical gardens. These gardens use minimal water and can support up to 150 plants of spinach or sukuma wiki, sufficient to feed a household of up to six people. Njuguna explained that a vertical garden with a circumference of about six meters can be harvested within 4 to 6 weeks. The ideal soil mixture involves one part soil to one wheelbarrow of manure, which enhances water retention and reduces the need for frequent watering.
Residents were advised to ensure their sites are well-drained and level before setting up the gardens. Njuguna also cautioned against using water containing chlorine directly on plants, as it may inhibit growth. To promote natural pest control, WICCO has encouraged farmers to plant onions within the cone gardens, which can repel insects without harmful chemicals.
Training on water harvesting techniques, such as installing gutters and using storage tanks to collect rainwater, was also provided to residents. These steps are expected to significantly alleviate water challenges in many households. Joseph Ng’ang’a Chege, a resident, expressed gratitude for the training, noting that the skills learned would help families achieve food security and possibly generate surplus for sale.
