CAPE TOWN BENEFITS FROM MULTI-AGENCY COOPERATION IN MARINE AND ENVIRONMENTAL LAW ENFORCEMENT AND LAUNCHES THE CITY OF CAPE TOWNS SPECIALISED MARINE AND ENVIRONMENTAL LAW ENFORCEMENT UNIT.
MEDIA STATEMENT February 2013.
The City of Cape Town has over 300km’s of coastline, one of its greatest economic, social and environmental assets. Although the City’s jurisdiction is determined by the high-water mark, economic, recreational, environmental and illegal activities operate across these jurisdictional boundaries. The inshore marine and coastal environment including the adjacent terrestrial environment is a central component to Cape Town offering many positive opportunities and attributes. Unfortunately, the trend of illegal activities and the lack of adherence to our country’s laws and City’s by-laws are impacting negatively on the marine and coastal environment and have strong relationships with organised crime and the drug trade within Cape Town with a subsequent negative impact on residents, local livelihood opportunities and the ecotourism potential of our city.
Marine and coastal management is a national government competency, but extent of the coastline, vast coastal waters associated with resource shortages, institutional complications, and a highly driven criminal element has resulted in limited actual and visible policing in the inshore marine and coastal environment,
There is increasing recognition that under-resourced local inshore coastal and marine law enforcement has a direct relationship with Cape Town’s many social challenges, including:
The Department of Agriculture, Forestry and Fisheries (DAFF) has an active programme in supporting municipalities to become operationally effective in the near inshore marine and coastal environment within municipal boundaries in order that they may support DAFF’s law enforcement and compliance efforts. Cape Town stands to be one of the first beneficiaries of this unique and new approach by DAFF. This in conjunction with the City of Cape Town prioritising law enforcement and compliance as one of the key strategies to create the Opportunity City, the Safe City, the Caring City, the Inclusive City and the Well-run City has resulted in a new partnership between the City and a number of other law enforcement agencies.
Following a two day workshop held in June of 2012, convened in partnership between the Department Agriculture Forestry and Fisheries (DAFF) and the City of Cape Town, it was agreed and recognised that a proactive multi-agency collaboration was needed to further address marine law enforcement. This workshop resolved that considering illegal activities, economies, safety and ecology took place across jurisdictional boundaries, the most appropriate means of effective policing and enforcement was through a collaborative Cape Town Marine and Coastal Law Enforcement and Compliance Task Team. The task team is chaired and led by DAFF and is tasked with multi-agency action, shared information and collective outcomes in the best interests of all of our citizens.
The Task Team was officially established in September 2012 and comprises representatives from the Department Agriculture Forestry and Fisheries, City of Cape Town Marine and Environmental Law Enforcement Unit, SAPS Borderline Police, Table Mountain National Park Marine Unit, SARS Customs, the National Prosecuting Authority, the Department of Environmental Affairs, CapeNature Conservation and the South African Maritime Safety Association (SAMSA). These are all the agencies responsible for marine and coastal law enforcement, management and regulation. The objective of Task team is to develop and implement a Cooperative Marine and Coastal Compliance and Law Enforcement strategy for the coastal zone within the City of Cape Town Metropole.
As a measure of its commitment to this partnership and role Mayoral Committee Member for Safety and Security, Alderman J.P Smith has provided his support and approval for the development of a City of Cape Town Marine and Environmental Law Enforcement Strategy and an associated specialised Marine and Environmental Law Enforcement Unit to work directly with this new Task Team. The new specialised and dedicated Marine and Environmental Law Enforcement Unit falls within the City’s law enforcement structures. The Department Agriculture Forestry and Fisheries have been supporting the City in this initiative, including the appointment of City Law Enforcement staff as Fisheries Control Officers in terms of the Marine Living Resources Act. The members of the unit have received specialised training in many aspects of marine and environmental law enforcement. They are also all fully qualified and trained lifeguards.
The Unit will work across the City in response to needs and addressing hotspots of illegal activity and non-compliance, as well as dealing with safety and security at the City’s beaches and coastal resorts. They will provide support to the all the agencies along the City’s coastline and act as a force multiplier when required. They will also be conducting regular inshore boat patrols on the City’s newly acquired law enforcement vessel.
All partners agreed that key to this partnership was regular and on-going joint operations with an increased visible presence along the coastline. This commitment was realised with the first of what will be many joint operations conducted from the 15th to the 18th November 2012. The operation was conducted under the operational command of DAFF and the SAPS Borderline Police, together with the City of Cape Town Marine and Environmental Unit, SARS Customs and the Table Mountain National Park Marine Unit and proved to be highly effective.
The unit has already achieved considerable success through increased visible policing in the coastal zone, stringent enforcing of the City’s by-laws and the Marine Living Resources Act. The unit has also assisted DAFF and SAPS in regulating control at the slipways along the City’s coastline.
Moving into the future the City will build on the current partnerships and inter-agency cooperation that has been established and will also be focussing on awareness around the Marine and Coastal environment and regulations.

CITY OF CAPE TOWN - 11 MAY 2012 - MEDIA RELEASE.
Public warned of presence of Blue-Green Algae in Zandvlei Marina canals.
The City of Cape Town would like to alert residents to the presence of a Blue-Green algal bloom in the Marina canals at the Zandvlei Estuary Nature Reserve.
The Zandvlei Estuary Nature Reserve experienced various problems over the past few weeks which included, amongst others, a bloom of Golden Algae and fish deaths. The most recent analytical results from the City’s Scientific Services laboratory (25 April 2012) showed a decline in the extent of the Golden Algae bloom. Although the algae is still present, it does not appear to have caused further fish to die off.
The Biodiversity Management Branch of the City’s Environmental Resource Management Department is undertaking regular inspections several times a week at a number of locations in both the Marina Da Gama and main vlei area. These inspections have shown improvement in water clarity. The sand prawns are active indicating that the golden algae bloom did not impact these organisms.
However, in the last day or so there has been a visible green colour in some of the blind-ending Marina Da Gama canals. It has been established that this is as a result of various species of Blue-Green Algae (Cyanophyceae). The occurrence of these species is of concern, because they can produce toxins. Eight samples were collected from various locations around the estuary (mainly the Marina canals and the outlet channel) on 10 May 2012, and analysed to test for the presence of toxins. No toxins were detected in the samples.
Although the algal bloom is not toxic, people and their pets should not drink from or swim in the Marina canals as an extra precautionary measure. Canoeing, sailing and other non-contact recreation sports are fine and the estuary therefore remains safe for these recreational activities.
Blue-Green Algae bloom in response to nutrients and warm, still conditions. Residents are asked to assist the City by reporting any increases in the extent of the bloom or any other unusual conditions that they observe. The succession of blooms from the Golden Algae to Blue-Green Algae not surprising, as nutrients are being recycled from one species to the next as the blooms wax and wane. The City will continue to monitor the situation very carefully.
Although the Marina Da Gama canals are a concern, the rest of the vlei and the mouth is recovering from the recent Golden Algae bloom. At this stage the mouth will probably remain open for the duration of winter, in accordance with the Mouth Management Protocol.
The pondweed harvesting was halted to assist the vlei in its recovery. However, loose weed broken during winter storms and from previously cut pondweed, is at present being removed. The Zandvlei Estuary Management Forum’s pondweed task team will discuss the way forward regarding harvesting within the week.
Zandvlei is Cape Town’s last effectively functioning estuary and supports at least 23 species of indigenous fish. Estuaries are particularly important as nurseries for many marine fish species and, as such, Zandvlei not only supports recreational fishing but acts as a haven for fish stocks targeted by small-scale commercial fishers in the adjacent marine environment. Zandvlei is one of the City’s 16 official nature reserves.
