Understanding scavengers, predators, their communities, ecosystems and conservation challenges

Vultures are a highly intelligent group of birds that provide important ecosystem services. Yet, populations of old-world vultures decreased dramatically in the last decades owing to anthropogenic factors. Efficient conservation strategies that address critical threats such as indiscriminate poisoning or depleted food sources need to be developed. At the same time, their behaviour including social interactions is still poorly understood. Building on high-tech tracking equipment and AI-based analytical tools, GAIA aims at better understanding how vultures communicate, interact and cooperate, forage, breed and rear their young. Additionally, the GAIA scientists research the social foraging strategies of white-backed vultures and the information transfer within carnivore-scavenger-communities. In the animal kingdom it is common across taxa that the search for food is undertaken not only as individuals but in a group. Animals forage together or rely on knowledge from other individuals to find food. This so-called social foraging presumably yields benefits, for example concerning the amount of food that is found, the size of prey that can be hunted or the time required to access food. GAIA investigates species-specific mechanisms in behaviour and communication as well as the incentives, benefits and possible disadvantages for individuals.

By further understanding these intra- and inter-speficic connections and interactions, GAIA also contributes to better understanding roots of human-wildlife conflicts (which are often connected to carnivore behaviour) and to species management. In Namibia for example, research into the lion communities helps understanding their spatial behaviour and mitigating contacts with the local population (e.g. cattle farmers) to manage human-wildlife conflict (GBF target 4). This knowledge is also utilized to observe and manage local lion populations sustainably to benefit people (GBF target 9), balancing conflict mitigation and tourism.

This building block is enabled by experience, funding and access: GAIA had the resources to hire excellent scientists with years of experience in investigating animal behaviour, spatial ecology, carnivore-scavenger interaction, intraspecific communication and human-wildlife conflicts. Additionally, GAIA stands on the shoulders of several decades of integration into science and stakeholder communities in wildlife management and conservation in southern Africa. This allowed access to protected/restricted areas with research permits to tag birds and collar carnivores for example. 

Newly published research results from the project (https://doi.org/10.1016/j.ecolmodel.2024.110941) confirm the benefits of cooperation and social information for foraging success. The results highlight social foraging strategies such as “chains of vultures” or “local enhancement” as overall more advantageous than the non-social strategy. The “chains of vultures” strategy outperformed “local enhancement” only in terms of searching efficiency under high vulture densities. Furthermore, the findings suggest that vultures in our study area likely adopt diverse foraging strategies influenced by variations in vulture and carcass density. The model developed in this study is potentially applicable beyond the specific study site, rendering it a versatile tool for investigating diverse species and environments.

Community engagement

Communities must benefit from the data collected, and we ensure they do.

We support quarterly data-sharing meetings between Northern Rangelands Trust (NRT) community conservancies and Big Life Foundation, creating an open forum where data informs collaborative decision-making. This includes town planning, land-use strategies and community-led conservation initiatives.

By sharing insights on wildlife movements, environmental conditions and human activity, communities can plan together for peace, security and the prevention of human-wildlife conflict (HWC). These sessions empower conservancies to co-develop solutions across landscapes, strengthening cross-border cooperation and ensuring that data drives action where it’s needed most.

Control over data sharing or privacy.

Community stewards are empowered and trained to collect data through different sensors, using the IoT network to feed data into control rooms and Earth Ranger. 

 

Technical support and training

CCF provides a holistic digital ecosystem integrating landscape-scale technology, training and community engagement to drive meaningful change, contributing to GBF Target 20 – Strengthen Capacity-Building, Technology Transfer, and Scientific and Technical Cooperation for Biodiversity.

Launching in June 2025, the Protected Area Technician (PAT) Training Programme has been developed by CCF to empower local communities to protect nature.

This tailored programme is designed to build practical, in-demand skills that create real opportunities—from entry-level technician roles to long-term careers in leadership and consulting within protected areas. Co-developed with industry experts and rooted in local needs, the curriculum blends hands-on field training with applied conservation technology knowledge.

Participants will graduate with job-ready skills to support and maintain vital conservation tech infrastructure. They’ll also have the opportunity to earn a PAT Certification, with a pathway to a globally recognised Cisco Certification—unlocking even broader career potential in the conservation and tech sectors.

By investing in local talent, the PAT programme helps communities take a leading role in protecting the natural landscapes they call home.

Monitoring of impact will take place through the first cohort of learners, focusing on their career journeys and personal development outcomes

Centralising data for management and control

A visualisation platform for real-time protected area management, helping managers make informed, conservation-related operational decisions. A community of users is now sharing best practices and innovative concepts, engaging EarthRanger as it extends beyond just elephant protection to a diversity of wildlife, ecological and community applications.

CCF has a long-term partnership with the AI2 Team, which developed this software. 

  • Data flows seamlessly from field-based hardware through the network into Earth Ranger
  • Diagnostic information is key to good support and maintenance.
Transporting data from the field to the operations room

From soil moisture and water levels to animal migrations and habitat health, data from sensors travels via Cisco LoRaWAN gateways and Actility’s ThingPark™ Platform to central operations rooms, where platforms like EarthRanger provide a comprehensive 360-degree view of ecosystem health and threats. Previously, these have been donated by Cisco Inc. 
These LoRaWan gateways now support over 800 IoT sensors across protected areas. 

  • When using LoRaWAN, data is transmitted wirelessly to a gateway. The gateway listens for the corresponding signals and transmits them to a LoRaWAN network server, which is connected to the Internet.
  • Deploying a LoRaWAN network is quicker and much more accessible than setting up a conventional cellular system.
  • Operation requires minimal infrastructure. Setting up cables and making connections to the power line is not required. Network design and optimisation are also simplified, as with one gateway, you can cover a larger area very effectively.
  • Reliable and long-term : The gateways are robust and come with a 7-year warranty, offering peace of mind and operational security for protected area managers working in harsh and remote conditions.
  • Unmatched coverage in rugged terrain: LoRaWAN technology continues to outperform alternatives in remote and rugged landscapes, providing extensive and reliable coverage across challenging terrain where cellular connectivity is limited or non-existent.
  • Seamless regional asset tracking: The system supports device roaming, allowing for uninterrupted tracking of assets across different regions without manual reconfiguration—an essential feature for mobile wildlife monitoring and conservation equipment.
  • Cost-effective: By leveraging low-cost, commodity-based hardware and integrating standard radio modules, LoRaWAN devices reduce overall deployment costs significantly. Compared to cellular or Wi-Fi-based solutions, this makes wide-area sensor networks more financially accessible for conservation teams.
  • A scalable and sustainable alternative: With its low power consumption, long range and minimal infrastructure needs, LoRaWAN provides a sustainable alternative to satellite communication. It enables real-time environmental monitoring in even the most isolated locations.
  • Widespread adoption for Conservation: Outside of this partnership, over 200 protected areas across the country are now using LoRaWAN to monitor vital resources like water, food, and habitat health. This growing adoption is helping secure a resilient future for wildlife, ecosystems, and the communities that depend on them.
