“…Zambia emphasizes the social considerations in their management of small-scale fisheries in Lake Kariba, and, as such, the rate of exploitation of fish is considered to be intensive than that is expected. A study on the small-scale fisheries of Lake Kariba conducted both on the Zambian and Zimbabwean side revealed that; unlike the Zimbabwean management regime, Zambian fishery regulatory authorities do not limit the number of nets that a fisher can use [33].…”

Abstract:Climate change continues to pose threats to fisheries and fishery-dependent communities globally. Vulnerability to climate change is a function of exposure, sensitivity, and adaptive capacity. Sensitivity is largely determined by the differences in socio-economic conditions among communities, and conflicts over resources often exacerbate this sensitivity. This study aims to understand factors affecting the sensitivity to climate change. The objectives are twofold: first, to develop indicators affecting sensitivity and to determine how they affect sensitivity, second, to compare sensitivity of two small-scale fishing groups (fishing camps and fishing villages). The study used twelve indicators, which are categorized into two; the community characteristics and assets, and threats and conflicts. Results show that fishing camps are less sensitive to climate change than fishing villages since they have more varied livelihood sources, such as crop farming. This allows for more sources of income. Both groups experience conflict with other lake users and wildlife attacks, which amplify their sensitivity through the reduction of fishing grounds and the damaging of fishing gear. It also shows that both climate and non-climate factors affect sensitivity, and understanding this can help to increase adaptive capacity. The findings allow for formulation of policy recommendations to help strengthen the livelihoods of small-scale fisheries.

“…Lake Harvest Aquaculture is an intensive vertically integrated fish farm encompassing each stage of production in the value addition chain whereby input levels are high and the feed is commercial and stocking density in triple net floating cages is high [1, 15]. The use of triple net floating cages in Lake Harvest has resulted in the commercial production evolving from 100 tons in 1996 to 10,200 tons in 2012 to 22,000 tons in 2021 and produces fish for domestic consumption and exports [1, 15, 26]. Contrary to intensive aquaculture practiced at Lake Harvest, which requires high investment, semi‐intensive aquaculture is practiced mainly by fishery cooperatives and the rural communities and few individual fish farmers in Zimbabwe [1, 8].…”

Zimbabwe is currently rated as one of the top 10 fish producers in Sub‐Saharan Africa. Fish farming in Zimbabwe is dominated by the culture of Nile tilapia (Oreochromis niloticus) followed by rainbow trout (Oncorhynchus mykiss). Over 90% of the cultured fish is O. niloticus, which comes from Lake Kariba. Since the first decade of the 21st century, there has been a significant increase in fish production from two tons to eight tons annually. The increase in fish production has been attributed to the government and donor‐funded fishery programs. In this review, current practices, opportunities, and challenges for aquaculture in Zimbabwe are highlighted. The current practices include intensive, semi‐intensive, and extensive aquaculture systems. Consistent high market demand for fish and numerous water bodies with potential for cage culture are some of the drivers for aquaculture. Despite the industry's significant growth, there are still a number of management and production issues that need to be resolved. Weaknesses in structural issues and operational frameworks in Non‐Governmental Organizations, lack of credit facilities, subsidies, limited technology, obfuscated governance, weak fish disease surveillance mechanisms and legal frameworks, and constrained human resources capacity are some of the challenges plaguing fish culture in Zimbabwe. Cogent aquaculture policies, sustainable subsidies, intensive training of human resources and fisheries experts, strengthened disease surveillance, cheaper alternative fish feeds, reliable viable fingerling production, concerted value chain efforts, and exploration of lucrative export markets is a panacea for the fledgling aquaculture industry in Zimbabwe.

“…The simultaneous optimizing of these objectives is rarely achieved [42]. For instance, the maximum exploitation of fisheries for employment opportunities means intensifying fish exploitation, which may abrogate the FAO Code of Conduct on conservation objectives [43]. As a result, identifying a suitable management approach in a shared social and ecological system can be complex due to diverse regulations and conflicting policies among member countries [28].…”

“…Apparently, classical management approaches in tropical fisheries are subject to debate on whether anthropogenic activities (artisanal fisheries) have a huge impact on the fish productivity [25,46]. Several researchers [14,25,46] argue that in tropical fisheries, the correlation between human activities and the level of the future fish stock has no considerable impact; it is characterized by uncertainties, where placing a maximum level of fishing effort may not lead to a fixed state of fishing mortality [43]. Thus, fish stock abundance and distribution are largely influenced by environmental parameters, such as river flows that are seasonally driven by the amount of precipitation received in the catchment [43].…”

Transboundary Fisheries Management in Kavango–Zambezi Transfrontier Conservation Area (KAZA-TFCA): Prospects and Dilemmas

et al. 2023

Inland fisheries in the Kavango–Zambezi Transfrontier Conservation Area (KAZA-TFCA) offer food security to the riverine communities across the region. They also contribute towards the attainment of the United Nations’ Sustainable Development Goals 1 and 15, which aim to alleviate poverty and maintain biodiversity conservation. Despite this significant role, the fisheries have suffered severe declines in the previous decades due to multiple factors, such as overfishing and poor legislation. Furthermore, climate change is exerting pressure by altering the ecology and productivity of the river systems. The unprecedented challenges of the COVID-19 pandemic have further constrained management efforts. Attempts to address these challenges have pointed towards transboundary fisheries management as a silver bullet in moving towards sustainable fisheries management. However, the implementation of this strategy in the region has encountered numerous roadblocks, thereby subjecting the river ecosystem to a wider environmental threat, with dire consequences on livelihoods. This paper reviews existing management and governance structures together with key informant interviews to elicit primary and secondary data essential for management at the regional level. The study identifies conflicting regulations, and inadequate policies and institutions across the region as major bottlenecks affecting the successful implementation of transboundary fisheries management. Finally, the paper offers some suggestions for the improvement of fisheries management in the region.
