This document provides an overview of the Wilderness Project's 2024 expedition to Lake Kariba, focusing on environmental monitoring, water quality, biodiversity, and conservation efforts. Lake Kariba and The Wilderness Project Overview The Wilderness Project conducted a 19-day scientific expedition along Lake Kariba to assess its ecological health, water quality, biodiversity, and human impacts, providing vital baseline data for sustainable management. ​ Lake Kariba's Geographical and Hydrological Significance Lake Kariba is the world's largest man-made reservoir, located on the Zambezi River between Zambia and Zimbabwe, covering approximately 5,580 km². ​ The expedition covered 834 km along the Zimbabwean side from the Zambezi River mouth to the Kariba dam wall. ​ The lake supports fisheries, hydroelectric power, and tourism. ​ Since its construction in 1959, it has been relatively well-studied but requires ongoing monitoring for sustainable management. Located 1,800 km upstream of the Indian Ocean, it is critical for regional water, food, and power security. Fixed Survey Sites and Data Collection Methods Systematic monitoring was established at 123 fixed sites for long-term ecological assessment. Data collected included aerial drone surveys, water quality tests, eDNA samples, macroinvertebrate assessments, pathogen samples, bat-call recordings, and island and tributary surveys. ​ Fixed sites enable comparison over time to detect ecological and water quality changes. ​ Drone flights and systematic sampling occur every 10 km along the lake shore and tributaries; eDNA and macroinvertebrates are sampled every 50-75 km. ​

This document provides an overview of a conservation-focused research expedition along the Middle Zambezi River, highlighting ecological, hydrological, and human activity data to support sustainable management and protection of the region's wilderness. Expedition Overview and Objectives The Wilderness Project conducted a 9-day research transect along the Middle Zambezi River from Kariba Dam to Luangwa Town to collect baseline data on hydrology, water quality, biodiversity, and human activity to support sustainable river management. 267 km traveled from Kariba Dam to Luangwa Town 12 team members from four African countries 31 research sites established Data collected included water quality, biodiversity, and river flow The expedition aimed to inform future monitoring and conservation efforts Middle Zambezi River and Surrounding Ecosystems The Middle Zambezi River flows through a UNESCO World Heritage Site, supporting high biodiversity and significant cultural history, with key features like Mana Pools National Park and the impact of Lake Kariba. Located between Lake Kariba and Cahora Bassa Part of the Mana Pools UNESCO World Heritage Site Supports high densities of large game, including over 6,000 hippos The landscape features mahogany, wild fig, acacia, and baobab trees Historically significant with evidence of stone age tools dating back 10,000 BC Mana Pools became a National Park in 1975 after elephant populations were nearly extirpated in the 1800s The natural landscape is maintained through local communities and conservation efforts Hydrology and Water Flow Dynamics The river's flow is heavily influenced by upstream dams, especially Lake Kariba and the Kafue River, with flow measurements indicating significant impacts from dam operations and drought conditions. ​ Total flow below Kariba Dam was 466 m³/s during the survey ​ Kafue River contributed approximately 380 m³/s, raising total flow to 849 m³/s downstream of confluence ​ River flow declines between sites likely due to dam releases and evaporation ​ Hydrological alterations affect erosion, sediment load, and aquatic biodiversity Water Quality and Environmental Conditions Water quality monitoring shows generally acceptable conditions but highlights issues like turbidity spikes and elevated pH linked to dam releases and natural processes. Water quality mostly within guidelines; turbidity spikes observed ​ Elevated pH levels require further investigation ​ Specific conductivity increased after the Kafue River confluence ​ Water quality influenced by upstream activities, including dam operations and natural weathering ​ Fluctuations in river levels impact erosion and sediment dynamics ​

This document provides a comprehensive overview of the Lower Zambezi River expedition, its methods, findings on hydrology, biodiversity, land use, and the socio-economic impacts on local communities. The Wilderness Project's Mission and Goals The Wilderness Project aims to explore, study, and protect 1.2 million km² of African wilderness by 2035 through partnerships with local communities, governments, researchers, and NGOs. Focuses on establishing hydrological and ecological baselines for Africa’s major river basins: Zambezi, Congo, Nile, and Okavango. Seeks to enhance conservation and understanding of Africa’s undocumented water sources and watersheds. Collaborates with multiple stakeholders including universities, government agencies, and local custodians. Aims to support biodiversity, ecosystem resilience, and socio-economic stability. The Zambezi River and Its Significance The Zambezi River originates in Zambia and Angola, flowing over 2,575 km to the Indian Ocean, supporting 30 million people and generating hydroelectric power. Flows through eight countries with a catchment area of 1,320,000 km². Critical for local livelihoods, food, and water security. The Cahora Bassa Dam (built in 1974) significantly altered natural flow and sediment transport, reducing peak floods and sediment by up to 70%. The river widens into the Zambezi Delta, a broad alluvial plain with diverse ecosystems, including extensive mangroves and the Marromeu Wetland. The delta has experienced landscape changes due to reduced flooding and sediment supply, leading to habitat loss and ecological shifts.

In 2023, The Wilderness Project launched a series of research expeditions in Southern Africa. One of the goals of these expeditions was to survey the Zambezi River, from its several sources to its outflow into the Mozambican Indian Ocean. As part of this effort, a research transect was conducted on the Zambezi River in Zambia — starting at the town of Chavuma at the Angolan border and ending downstream of the Barotse Floodplain at Sioma. The total distance of the transect was 560 km, all of which was travelled in purpose-built canoes. This report summarises the findings of the expedition and presents an assessment of the health, human development, and ecology of the Zambezi River between Chavuma and Sioma.

Kavango-Zambezi Transfrontier Conservation Area (KAZA TFCA), is a transboundary collaborative initiative of five Partner States, Angola, Botswana, Namibia, Zambia and Zimbabwe, in the conservation of shared natural resources and the development of the communities in and around the landscape. The TFCA is a mosaic of multiple land uses composed of: • Protected areas (PAs) in the form of national parks, game reserves; • wildlife/game management areas, forest reserves, and conservancies/ community concessions areas, and • Communal areas (settlement, pastoral, and arable farming). There are about 3 million people settled across the KAZA landscape. The human population is mainly rural communities that are largely dependent on subsistence pastoral and arable agriculture. The multiple land use status of the KAZA landscape present many development challenges and opportunities for the resident communities. Humans have been battling insect pests for as long as we have shared this planet. Insects are everywhere and no human being can avoid interacting with insects in all facets of life. In humans’ view, any insect that is found in the wrong place becomes a pest and is a source of human insect conflict. Insect pests are those that feed on, compete for food with, or transmit diseases to humans and livestock. Ecosystems modified by human activities have provided opportunities for varied insect species to successfully adapt and thrive as pests. In popular sense, “insect” refers to familiar pests or disease carriers, such as houseflies, ants, locusts, termites, grasshoppers, aphids, mosquitoes, fleas, butterflies, bees, hornets and tsetse flies. Some of the specified insects cause serious problems in people’s houses, farms, rangelands, rivers, dams and towns across the world. The Kavango-Zambezi (KAZA) Transfrontier Conservation Area (TFCA), located in the sub-tropical region, provides favourable conditions for multiplication of many insects that attack people’s crops, livestock and products and those that carry disease. Such interaction with human life causes serious human insect conflict (HIC). Massive efforts are required to suppress and manage population densities of the varied and abundant insect species in order to mitigate the HIC. This manual provides information on methods of reducing and mitigating human-insect conflict.
