Hunting and fishing support diverse food systems in tropical forest areas, but carry serious occupational risks. Health and safety at work is important to human wellbeing and constitutes an element of Indigenous rights. This issue has received attention in the regulated sector, but needs additional focus in subsistence and informal economies. We draw on semi-structured interviews with Turumbo hunters and fishers in the Yangambi Biosphere Reserve region (DRC) to assess perceptions of occupational risk, especially attacks from wild animals. Fishers were concerned about drowning and cuts, while hunters cited bad weather and injuries from faulty equipment. There was gender-specific perception of risk from wild animals that reflected different roles: women noted snake bites and wasps, while men feared larger animals. Retaliatory behaviors among respondents included killing various species. The risks associated with fishing and hunting in tropical forests should be addressed in policies that consider the wellbeing of the poor.

Community-based monitoring, assessment and management of data-limited inland fish stocks in North Rupununi, Guyana
Inland fisheries are important for food security in communities around the world, especially in developing countries. In North Rupununi, Guyana, the state of exploited stocks is poorly understood, and fishery monitoring and assessment are challenging because diverse fishing gears and target species are distributed across a heterogeneous landscape. This complexity created an opportunity for community-based monitoring (CBM) to support data-limited assessment. Standardised CBM was established for the North Rupununi as part of a new inland fisheries management plan initiated by indigenous community groups with support from the government. Quantitative length-based assessments undertaken for target stocks suggested moderate levels of exploitation consistent with local perception. Our study highlights that local experts and community participants with different levels of training can collect accurate biodiversity data. Further development of CBM is important in North Rupununi. We recommend using local ecological knowledge indicators to track spatial and temporal patterns in exploitation and fish stock status.
An approach to assess data-less small-scale fisheries: examples from Congo rivers
Small-scale fisheries (SSF) account for much of the global fish catch, but data to assess them often do not exist, impeding assessments of their historical dynamics and status. Here, we propose an approach to assess ‘data-less’ SSF using local knowledge to produce data, life history theory to describe their historical multispecies dynamics, and length-based reference points to evaluate stock status. We demonstrate use of this approach in three data-less SSFs of the Congo Basin. Fishers’ recalls of past fishing events indicated fish catch declined by 65–80% over the last half-century. Declines in and depletion of many historically important species reduced the diversity of exploited species, making the species composition of the catch more homogenous in recent years. Length-at-catch of 11 of the 12 most important species were below their respective lengths-at-maturity and optimal lengths (obtained from Fishbase) in recent years, indicating overfishing. The most overfished species were large-bodied and found in the Congo mainstem. These results show the approach can suitably assess data-less SSF. Fishers’ knowledge produced data at a fraction of the cost and effort of collecting fisheries landings data. Historical and current data on fish catch, length-at-catch, and species diversity can inform management and restoration efforts to curb shifting baselines of these fisheries. Classification of stock status allows prioritizing management efforts. The approach is easy to apply and generates intuitive results, having potential to complement the toolkits of researchers and managers working in SSF and engage stakeholders in decision-making processes.
Improved practices for forest management and fish smoking in Cameroon’s mangroves
Key messages
- Mangrove forests, which serve as breeding grounds for fish and crustacea, contribute to livelihoods of communities living on Manoka Island in Cameroon. In the absence of sustainable management mechanisms, these same mangrove forests and livelihoods are under pressure due to overharvesting of wood for fish smoking.
- Sustainable woodfuel value chain options for Manoka were identified through a scoping study and exchanges at a multistakeholder platform, which built the foundation for successful participation.
- The improved brick and metal smokehouses, developed and tested in collaboration with a women’s fish-smoking association (AFUMA), reduced wood consumption by 33% and 88%, and smoking time from three days to two days and one day, respectively.
- Forest conservation, forest production and reforestation zones were designated by the Manoka Community Forest management institution based on a consensual local land-use plan with stakeholders.
- Plan Vivo, as the chosen environmental standard, contributed to the successful submission of a Project Idea Note (PIN) for a planned PES project and to developing the community’s own code of conduct for improved management of mangrove forests.
- The sustainability of interventions to reverse the mangrove forest degradation and deforestation trends on the island depends on further appropriation by the local council and other stakeholders, as well as on their capacity to replicate and scale up improved management, harvesting and smoking practices.
Worrying decline of fish in the Congo River: Evidence from a site in Tshopo Province
Key messages
- Evidence shows severe decline in many fish species in site along the Congo River in Tshopo Province
- Fish are essential sources of nutrients in local diets and important for livelihoods
- Urgent need for better management of fisheries before problem becomes even worse
- Any management solution will depend on active participation of the fishers themselves
Quantifying the contribution of mangroves to local fish consumption in Indonesia: a cross-sectional spatial analysis
Indonesia has lost more mangroves than any other country. The importance of mangroves for carbon storage and biodiversity is well recognised, but much less is known about what they contribute to the communities living near them who are called on to protect them. Malnutrition in Indonesia is high, with more than a third of children stunted, partly due to poor diets. Fish are nutrient-rich and are the most widely consumed animal source food in Indonesia, making the relationship between mangroves and fish consumption of great importance. Aquaculture is also tremendously important for fish production in Indonesia and has replaced large areas of mangroves over the last two decades. We performed a cross-sectional, spatial analysis in this study. We combined data on fish consumption for rural Indonesian coastal households from the Indonesian National Socioeconomic Survey with spatial data on mangrove forest and aquaculture area from the Indonesian Ministry of Environment and Forestry to create a cross-sectional spatial dataset. Using a mixed-effects regression model, we estimated to what extent living in proximity to different densities of mangroves and aquaculture was associated with fresh fish consumption for rural coastal households. Our sample included 6741 villages with 107 486 households in 2008. The results showed that rural coastal households residing near high-density mangroves consumed 28% (134/477) more fresh fish and other aquatic animals, and those residing near medium-density mangroves consumed 19% (90/477) more fresh fish and other aquatic animals, than coastal households who did not live near mangroves. Coastal households that lived near high-density aquaculture consumed 2% (9/536) more fresh fish, and those that lived near medium-density aquaculture consumed 1% (3/536) less, than other rural coastal households.
Technical Report on Site Based Research in Ghana and The Gambia: Land-seascape Food and Nutrition Profiles
Diversified food system strategies can improve food composition and income sources for women oyster harvesting communities dependent on seasonal fishery activities. This study focused on women shellfishers in Densu Estuary, Narkwa Lagoon, and Whin Estuary in Ghana and in Tanbi, Bulock, and Allahein estuaries in The Gambia, and to understand the status and opportunities for increasing the use of biodiversity to meet seasonal food and dietary needs. Research activities included site scoping assessments, 21 focus group discussions in Ghana (5) and The Gambia (16) and 356 random household interviews in Ghana (211) and The Gambia (145). In addition, data validation and feedback discussion meetings were conducted with communities across the six study sites. Overall, assembled data covered household livelihood characteristics, food production, food types, seasonality and expenditure attributes, tree planting, nurseries, species diversity and management, local food portfolios, and oyster and fisheries resource use challenges.
Land-use and land-cover affect inland fish catch in two rivers of Central Africa
Land-cover change can affect inland fisheries, which underpin food security of millions of people worldwide. Removal of forests from very large floodplains has been found to decrease fish catch via loss of feeding and nursery habitat for fish. However, it is unknown if similar effects occur in smaller rivers with limited floodplain areas. Little is also known about the mechanisms by which land-cover changes affect inland fish catch. Here, we assessed land-use and land-cover (LULC) effects on fish catch, diet, and condition at sites in two medium-sized rivers of Cameroon, in Central Africa. We found that LULC explained 30% of the variation in fish catch, with the catch of five species being positively, and of two species being negatively, related to floodplain forests. The niche breadth of fish diets was higher in the river surrounded by forests than in the river surrounded by agricultural land. However, contrary to expectations, condition of the fish, as indicated by occurrence of diseases or deformities, eroded fins, lesions or tumors, was not related to LULC. Our results support the notions that floodplain forests support fish populations in rivers with limited floodplain areas in ways similar to that of rivers with large floodplains, and that LULC affects fish populations via changes in fish diets and instream habitat features (i.e., riparian canopy closure, water clarity, substrate heterogeneity, and habitat volume). These effects imply that prevailing changes in LULC threaten the food and livelihood security services provided by inland fisheries, highlighting the importance of policies that maintain native vegetation along riverbanks and in floodplain areas.
Impact of Mekong River biodiversity on the food culture of women and children in Prey Veng, Cambodia
Situated in the heart of the Mekong River basin, the biodiversity of Cambodian freshwaters is high, with around 475 fish species. Fisheries have shaped Cambodian culture, including traditional diets. Fish and other aquatic animals are the main and culturally preferred animal-source foods in a population vulnerable to food insecurity and malnutrition. The food culture of consuming fish with the bones and head is nutritionally valuable, providing high-quality nutrients. The objective of this study was to assess the consumption of fish and other aquatic animals among mothers and their young children, with details on species, types of processing, and parts consumed. We interviewed 100 mothers in Prey Veng Province, Cambodia, on fish and other aquatic animals consumed by themselves and their children (one child per mother) during the preceding rainy season. To support recall of fish consumption, we used 157 cards with pictures of fish and other aquatic animal species and 11 cards with processed fish. Our results showed that species diversity in mothers’ diets was higher than that of their children; on average, mothers and children consumed 69 and 14 species of fish, eight and one species of other aquatic animals, respectively, in the preceding rainy season. On average, mothers reported they knew of 113 fish species and 14 other species available in their surrounding environments. Consuming fish with the head and bones is common among mothers but not children. Our study showed that the rich biodiversity of aquatic animals in the Mekong River is reflected in the food culture of mothers, but not in children. Consequently, children in their most critical period, do not harness the nutritional benefits from the rich aquatic biodiversity. We suggest policymakers recommend feeding young children with a larger diversity of aquatic animals and promoting fish processing to allow young children to benefit from the rich aquatic diversity and their nutrient-rich parts.
Perceptions and attitudes towards climate change in fishing communities of the Sudd Wetlands, South Sudan
The Sudd in South Sudan, formed by the White Nile’s Baḥr al-Jabal section, is one of the largest and most important wetlands in the world. Communities in the region almost exclusively depend on fisheries for food and livelihoods. Although threatened by over-exploitation and habitat changes, fish populations are also affected by climate change. Using semi-structured questionnaires, we assessed fisherfolk’s opinions of how recent variation in climate affected their livelihoods and the environment. Fisherfolk perceived that climate had changed in the past decade and were negatively impacted by this. Interviewees reported average higher temperatures, a greater frequency of floods and droughts, unpredictable timing of seasons, and erratic rainfall. Destruction of fishing villages/camps, loss and damage of fishing equipment, shifts in the fishing calendar, reduction of fish trade, and fish catch declines as well as psycho-social problems were given as the major consequences of climate change. Causes of climate change and variability were perceived to be linked to uncontrolled harvest of forest resources, anger of God and ancestors, and natural variability in climate. Most respondents expressed a desire to adopt more responsible behavior such as planting trees and establishing community nurseries, being educated on climate change risks, and sustainable fisheries management. Our results show that fisherfolk in the Sudd are troubled by climate change impacts on their livelihoods and on fish populations. In South Sudan, climate change has been reported from hydroclimatological data but concrete impacts on people remain largely unknown and of little concern because of recent wars and the poor economy. Our study provides an example of how fisherfolks’ local ecological knowledge (LEK) can be used as an early warning system of the negative impacts on livelihoods and fish populations and support adaptation to the changing climate.
