The Kavango Zambezi Transfrontier Conservation Area (KAZA) is the world’s largest land-based transboundary conservation area. It spans parts of five southern African countries—Angola, Botswana, Namibia, Zambia, and Zimbabwe. KAZA was officially established in 2011 by the five partner countries to protect the region’s valuable, shared biodiversity and important ecosystems. At 106 million acres, KAZA is roughly the size of France and encompasses a mosaic of interconnected land-uses including national parks, forest reserves, and community managed areas.  

KAZA’s extensive woodlands, grasslands, and wetlands provide critical habitat for lions, wild dogs, and the planet’s largest population of savanna elephants to move across borders and between conservation areas. Flowing through this region are KAZA’s three main rivers, the Zambezi, Kwando, and Okavango, which support critical habitats that KAZA’s people and wildlife depend upon.  

At the heart of the KAZA vision is the premise that conservation can be the economic driver of the region, resulting in a thriving landscape where wildlife and people coexist. To achieve this, WWF assists KAZA country governments, communities, and other partners to protect wildlife, secure freshwater, promote tourism, and support the socioeconomic well-being and resilience of local communities, ensuring that the people who live alongside KAZA’s iconic wildlife are at the forefront of our conservation planning and actions.

The centerpiece of KAZA is its wildlife, which plays a critical role in maintaining KAZA’s ecosystem. This includes the world’s largest population of elephants (~228,000), more than half of Africa’s remaining savanna elephant population, which live and move through this region. As “landscape architects,” elephants clear trees in wooded areas and disperse seeds while they move and forage, which lets new plants grow and forests regenerate naturally. However, in areas with a surplus of elephants, they can actually damage the ecosystem, which is why securing KAZA as a connected landscape to allow elephants and other wildlife to freely move is so important.

It’s also a crucial conservation landscape for large carnivores, including an estimated 25% of Africa’s wild dogs, almost 20% of the continent’s lions, and approximately 15% of the world’s cheetahs. These predators help balance the ecosystem by keeping herbivore populations, such as wildebeest, zebra, and buffalo, at healthy levels.

KAZA’s rivers are also home to economically important and endemic freshwater fish. Once such species is the tiger fish, a top predator that can reach up to three feet in length and a target of the region’s sports-fishing industry.

People & Communities

KAZA has a sparse human population of approximately 2.7 million, with most residents heavily dependent on small-scale agriculture and subsistence use of natural resources. KAZA’s ultimate success depends on the commitment of these communities to sustainably use and manage their natural resources. This can only be achieved if they are active and equal participants in relevant planning and decision-making about their land and resources, and have strong incentives to value and protect wildlife. Empowered communities are also a powerful deterrent against poaching for meat and the illegal international wildlife trade. WWF has long supported community-based natural resource management efforts across KAZA, designed to advocate for and support local and Indigenous communities’ role as the rights-holders and beneficiaries of their land, water and natural resources. This simultaneously increases community resilience to the impacts of climate change and future pandemics. 

Threats

Climate change

KAZA falls almost entirely within an African geographic zone considered to be most at-risk from climate change. The impacts are already evident: changing seasonality of rainfall, heatwaves, droughts, and flooding are impacting local peoples’ livelihoods, threatening food and water security, and species’ survival. These factors can exacerbate habitat destruction and human-wildlife conflict as people and wildlife struggle to adapt and compete for access to declining natural resources.

Habitat loss, fragmentation, and degradation

KAZA's expanding human footprint is causing the loss, degradation, and fragmentation of important freshwater and terrestrial ecosystems. This forces wildlife to move through human-dominated areas, resulting in a higher risk of conflict. Agriculture, expanding villages and towns, and linear infrastructure in the form of roads, fences and railroads, are also degrading critical wildlife habitat, including wildlife corridors that allow elephants and other wildlife to move seasonally and between protected areas. The effects of climate change, coupled with the threat of large-scale dam development, risk disruption to seasonal flows of water and fragmentation of rivers.

Human-wildlife conflict

KAZA’s wildlife lives alongside human communities with their own needs for water, food, farming, and grazing land for livestock. However, longer and more frequent droughts due to climate change and increasing interactions with humans and associated development are driving competition for space and water access, and therefore human-wildlife conflict.

More conflict is predicted as populations of elephants and large carnivores rebound and reclaim their historical ranges. In some of those places, the communities living there have little recent experience or tolerance for living with wildlife.

Wildlife Crime

KAZA’s wildlife, particularly elephant, rhino, and pangolin, are threatened by poaching for their parts for the illegal international wildlife trade. In fact, wildlife crime, which is undertaken by internationally operating criminal networks, is the greatest threat for these species. Pangolins are fast becoming the most trafficked species in the region, with Namibia reporting more pangolin-related criminal cases in the past few years than for rhinos and elephants combined. There are also indications that illegal bushmeat hunting for subsistence and commercial use increased in KAZA due to the livelihood impacts of the global COVID-19 pandemic—a trend that may continue if community benefits from conservation and related activities do not increase.

Unsustainable Infrastructure Development

KAZA’s natural resources and biodiversity are threatened by development of high-impact infrastructure including large scale energy and water infrastructure, roads, railways, and urban development. This is leading to increased habitat loss and fragmentation, threatening wildlife migration corridors, agriculture, and freshwater sources. New hydropower projects, particularly in Angola where KAZA’s headwaters are located, can fragment the few remaining free-flowing rivers, blocking critical migratory routes for freshwater fishes and altering crucial downstream water flows.

What WWF Is Doing

Fighting wildlife crime

Each year in Africa, poachers kill thousands of elephants, hundreds of rhinos, and hundreds of thousands of pangolins for the illegal international trade in their ivory, horns and scales. Wildlife crime is a major threat to KAZA’s wildlife. It endangers the wellbeing and livelihoods of local people, enhances corruption, and erodes good governance. WWF is strengthening collaboration between KAZA countries to disrupt transboundary operating criminal networks through support to anti-poaching patrols, information exchange, investigations, and prosecutions.

In Namibia, WWF is supporting the country’s successful “whole of government” national wildlife crime program, a collaboration between all law enforcement agencies, civil society (including communities), and conservation partners. As a result, the number of wildlife criminals caught and receiving meaningful sentences has dramatically increased, which is also helping to deter others from committing similar crimes.

In Zambia’s Kafue National Park, WWF and partners installed an innovative anti-poaching system using thermal imaging technology to help authorities detect and respond to wildlife crime. For example, rangers and park staff can now monitor illegal incursions into the park via Lake Itezhi Tezhi using thermal cameras. Integrated artificial intelligence on the cameras enable real-time video alerts to be sent to rangers when the cameras detect illegal boats entering or leaving the park.

We also partnered with Zambia’s Department of National Parks and Wildlife and Game Rangers International to pilot a new long-range wireless technology in elephant collars to track and monitor orphaned elephant calves in Kafue. The data will help to improve conservation management plans, identify wildlife corridors, and protect elephants and other wildlife in the area.

Securing landscape connectivity

In order to ensure KAZA’s wildlife species populations are able to thrive, identifying and addressing the threats to habitat connectivity and critical wildlife corridors must be prioritized. 

To secure the long-term viability of KAZA elephants as a transboundary population, we first needed to establish a current and relatively precise baseline of elephant numbers and movements in the region. To achieve this, WWF and KAZA partner countries conducted the first synchronized transboundary survey of KAZA’s elephants in 2022. We also contributed to the region’s first elephant connectivity policy brief published in 2023. The data from these two studies will informs KAZA’s recent policy recommendations on securing and maintaining elephant movement corridors and landscape connectivity to help ensure long-term protection and management of Africa’s largest transboundary elephant population.  

Protecting KAZA’s freshwater resources

KAZA’s three main rivers—Okavango, Zambezi, and Kwando—sustain people and wildlife in southern Africa’s otherwise dry landscape. These rivers support critical migratory corridors and seasonal habitats that the region’s people and wildlife depend upon. 

WWF and partners are working to secure the region’s free-flowing rivers, particularly the Kwando River, and manage the water resources of the Kwando Basin. For example, we co-developed a “report card” on the health of the Kwando River Basin, an approach that’s been successful elsewhere in planning for the wise use of water. This supports recommended actions like implementing environmental flows for the basin and creating national and regional Kwando water resource management plans. 

In Zambia, WWF is engaging the government and other interested parties to advance low-carbon, low-cost, and low-conflict energy solutions that meet Zambia’s energy needs while limiting the impact of new hydropower development. We intend to undertake similar work in Angola to advance protections for KAZA’s headwaters.  

Reducing human-wildlife conflict

Permanent enclosure for livestock

WWF has invested in science-based connectivity studies to improve the understanding of the abundance, distribution, and movement of key conflict species including elephants, lions, and spotted hyena in KAZA. We then can identify important connectivity pathways and conflict hotspots to  guide which conflict management approaches to implement and where to do so, as well as influence land use and management decisions to prevent human-wildlife conflict from occurring in the first place. 

WWF also works with communities and local partners to find solutions to better manage and reduce conflict on the ground. Management approaches to conflict vary but successful approaches include: 

  • Predator-proof livestock enclosures: These structures successfully protect livestock from predators, most often lions and spotted hyenas, by preventing losses for farmers and reducing the likelihood of farmers killing predators in retaliation for harming livestock.  
  • Early alert systems: Using data from collared animals, these systems provide real-time alerts to communities about the presence of wildlife, particularly lions, allowing timely preventative measures. 
  • Clustered farms: Farmers cluster their agricultural fields outside of key elephant corridors and use electric fences to prevent elephants from eating their crops and causing food insecurity. 
  • Secured water storage: In search of water, elephants can damage or destroy water infrastructure so communities build elevated water storage for clean drinking water.  
  • Community Guardians: Local partners employ and train Community Guardians to help communities build new and reinforce traditional livestock enclosures, monitor wildlife, respond to incidents of human-wildlife conflict, and advise farmers on livestock management approaches to prevent conflict. 

Adapting to climate change

WWF is working to help both people and wildlife adapt to a rapidly changing climate and improve food and water security.  

Through the Climate Crowd initiative, WWF works with communities to collect and analyze data, present it back to them, and develop and implement on-the-ground climate adaptation solutions. Improving adaptation strategies benefits wildlife too, as the nature-based and nature-friendly solutions help communities cope with climate impacts while reducing pressure on wildlife and conservation areas. Following a successful pilot project assisting communities near Zimbabwe’s Victoria Falls, WWF is now scaling this work across multiple sites in KAZA, with solutions focused on increasing water security, climate-smart agriculture, alternative livelihoods, and reducing human-wildlife conflict.

Supporting community-based conservation

In Namibia, communal conservancies are a globally recognized conservation success story. They began in the late 1990s following groundbreaking legislation that put the rights to, and responsibilities for, conserving wildlife in the hands of the communities living with it. WWF, the Namibian government, and local NGO partners helped create the conservancy model and we continue to partner with local communities to help them manage their natural resources and ensure a future that includes healthy wildlife populations and sustainable economic growth. Conservancies have helped to recover many wildlife populations in Namibia, which in turn has contributed to wildlife-based enterprises like tourism, providing incentive for people to conserve wildlife.  

With the sharp downturn of tourism due to the COVID-19 pandemic, WWF has been helping to support tourism recovery in southern Africa, including developing the African Nature Based Tourism Platform. The platform connects funders to communities and small to medium-sized businesses impacted by the COVID-19 pandemic across 11 countries, including Botswana, Namibia, Zimbabwe, and Zambia. WWF is also helping communities reduce over-reliance on tourism by diversifying income sources. Wildlife credits offer one innovative financing mechanism for communities that have set their lands aside for conservation. With this approach, conservancies can increase their resilience and financial independence so that, when future shocks to the tourism industry arise, communities and conservation are secure. 

Projects

  • Wildlife Crime Technology Project

    Over four and a half years, the Google.org-funded Wildlife Crime Technology Project (WCTP) provided WWF a platform to innovate and test a number of innovative technologies, many of which have the potential to change the course of the global fight against wildlife crime. 

  • Conserving Wildlife and Enabling Communities in Namibia

    Namibia is home to an array of wildlife, from ostriches and zebras roaming the gravel plains to penguins and seals chilling in the Atlantic currents. It was the first African country to incorporate protection of the environment into its constitution. With WWF’s help, the government has reinforced this conservation philosophy by empowering its communities with rights to manage and benefit from the country’s wildlife through communal conservancies.
