Persistent illegal urban agriculture, exacerbated by food shortages, continues to compromise the environmental integrity of the capital.
Unsustainable illegal urban farming in wetlands, steep slopes and stream banks in suburban Harare including Highfield, Glen Norah, Warren Park 1, Epworth, Kuwadzana Extension, Waterfalls and Mabvuku Tafara continues cause massive land degradation, destroying ecosystems and compromising water availability.
With unpredictable weather and persistent droughts due to climate change, Harare could find itself struggling with water supplies as urban farmers disturb and vandalize wetlands for agriculture.
Environmental Management (EMA) spokesperson Amkela Sidange has expressed concern about the increase in illegal urban farming activities which she says are disrupting the city’s aquatic ecosystem.
Sidange noted that according to Article 20 of Statutory Instrument 7 of 2007, it is an offense to carry out any operation in a protected ecosystem such as wetlands, river banks and streams.
Anyone who contravenes this article is liable to a fine not exceeding level fourteen or imprisonment for a term not exceeding 6 months; or to both such a fine and imprisonment.
“Cultivation, when practiced in the mentioned areas (wetlands, banks and waterways), leads to their degradation.
“For example, wetlands in Zimbabwe cover only 3% of the country’s total land area, which is about 0.26 million hectares, but despite being such an insignificant statistic, wetlands have a vital ecological role which includes, among other things, a balance between water quality and quantity.
“Their degradation therefore involves the loss of the groundwater recharge system resulting in the drying up of boreholes and water bodies such as rivers and dams, which is very common in recent times.
“Wetlands act as the earth’s kidneys removing impurities from water, and therefore degradation of this vital ecological system results in poor quality water being available for use,” she said.
Sidange reiterated that the EMA is embarking on several initiatives and campaigns to educate city dwellers to become eco-responsible and avoid illegal urban agricultural practices.
Environmental hazards caused by unsustainable illegal urban agriculture have made it more expensive for local authorities to treat water for domestic use as it will need more chemicals to improve its quality as destroyed wetlands can no longer effectively remove impurities.
Acting Harare City Council (HCC) spokesperson Innocent Ruwende said urban farmers should seek guidance from local authority regulations before ignorantly embarking on the practice.
“Farming on wetlands, stream banks and steep slopes is illegal. We discourage such practices,” he said.
Warren Park 1-2 Councilor Tichavona Mhetu spoke to residents of his ward about the dangers of illegal urban farming.
“I held several meetings with urban farmers to highlight the sustainability issues of the farming methods they employ. I also informed them of the alarming rate at which Lake Chivero is silting up.
“I then advised them to make new applications to the council so that the council could then turn down candidates practicing riverbank farming and steep slope farming. Hundreds of farmers applied, and then I hired the director housing to come up with a model and hopefully it will be ready for the next farming season,” he said.
In Warren Park 1-2, farming on steep slopes, terrain like mountain slopes, affects slope stability, increasing the chance of landslides as well as general soil erosion.
Climate change, the product of environmentally hazardous human practices, has been felt more intensely of late, with Cyclone Ana wreaking havoc last month in Chipinge, Chimanimani, Muzarabani and Nyanga.
