The research team, led by Esther Mufungizi Ahana of the Université Evangélique en Afrique in Bukavu, interviewed 63 stakeholders across the two conflict hotspots, including 56 farmers, two community leaders and five wildlife or institutional actors. A further 24 people from all of these categories took part in two focus group discussions, one in each village. Data collection ran from August to October 2025 and combined semi-structured interviews, focus groups and non-participant field observations of farms, wetlands, riversides and known conflict sites. Interviews were conducted in French, Swahili or Kifuliru, transcribed verbatim and analyzed thematically, with triangulation across sources, methods, member checking and peer briefing used to strengthen the credibility of the findings.

What emerged is a portrait of multidimensional vulnerability. Every single one of the 63 interviewees reported crop destruction by hippopotamuses, and 51 described fatal attacks on people. Participants said the animals destroy harvests, make nighttime and early-morning movement dangerous, and contaminate the river water that communities rely on for washing, fishing, livestock watering and, in some cases, domestic use. One resident of Katogota told the researchers that hippopotamuses constitute a permanent threat, attacking people in the fields and creating insecurity especially at night, and that after the animals pass through, the river water often becomes contaminated and causes illness among children and livestock. The authors stress that such statements capture perceived risks rather than verified health outcomes, since the study conducted no water testing, pathogen surveillance or veterinary assessment.

The timing of danger follows a biological logic that villagers often understand poorly. Hippopotamuses are herbivores that graze on land mainly under cover of darkness, and where agricultural fields sit directly on their feeding routes and wetland corridors, encounters are almost inevitable. Female hippos become exceptionally aggressive while nursing their young, perceiving any nearby human as a threat to their calves. Fifty-two of the 63 participants identified these reproductive and maternal-care periods as especially dangerous. One Kamanyola resident explained that when females are nursing, they attack anyone who approaches, causing damage and loss of human life. The researchers emphasize that this aggression is not random but rooted in defensive instincts, meaning that risk peaks predictably in precisely the zones where farming has expanded.

The legal framework compounds the tension. Hippopotamuses are protected under Congolese conservation law, and laws prohibiting retaliation place residents in what the authors call a moral and security dilemma: defending crops and lives can bring severe criminal penalties. A respondent in Kamanyola described how people who kill a hippopotamus that threatens them are immediately transferred to Bukavu and imprisoned. Forty-three participants said wildlife protection appears to take precedence over human safety, and fifty-seven felt that insufficient attention is paid to the risks and losses they endure. There is no compensation mechanism for affected households, and the researchers link this absence to deep institutional mistrust and to perceptions that the state prioritizes ecological and tourism values over community survival.

These grievances have a political-ecological dimension. The study deliberately pairs the One Health framework, which treats human, animal and ecosystem health as interdependent, with political ecology, which examines how power relations and institutional arrangements distribute environmental risks and benefits. The Ruzizi Plain lies at roughly 800 meters elevation between the Mitumba Mountains and the Congo-Nile Ridge, with semi-arid conditions and alluvial soils that support intensive farming. Earlier ecological surveys along the Ruzizi River recorded 145 hippopotamuses, alongside hundreds of feces, footprints and tracks, with activity concentrated in the Nyangara and Kahorohoro wetlands and damage hotspots including Katogota. Habitat fragmentation has accelerated through armed conflict, population displacement, agricultural expansion and urbanization, and despite legislation barring settlement within 100 meters of riverbanks and lakeshores, such settlement remains widespread.

The human consequences extend well beyond lost harvests. Sixty-one of the 63 respondents described substantial psychological and social effects: persistent fear, recurrent bereavement, trauma after deaths, and a feeling of abandonment by public authorities. One Katogota participant said it is impossible to go two years without witnessing deaths caused by hippopotamuses, and that neighbors, brothers, sisters, fathers and mothers become victims while communities feel ignored. Food insecurity deepens as agricultural income collapses, and residents reported resorting to improvised crop-protection measures and even gathering food in high-risk areas. The authors frame this as an unequal distribution of risk in which local communities absorb the costs of living with wildlife without adequate protection, a pattern they interpret through the lens of environmental justice.

Adaptation efforts so far have been only partially effective. Non-governmental organizations and state authorities have built protective enclosures, but residents told the researchers these structures cannot withstand the strength of hippopotamuses, eroding trust in state-led interventions. Other measures discussed included restoring public electricity services to light village perimeters and even providing food resources to divert animals from fields. Participants also mourned the erosion of traditional, non-lethal deterrence: night guarding, fires, shouting and drumming, practices that elders once used to keep animals away. Such techniques have lost effectiveness as animals habituate, while restrictive rules now forbid communities from acting, leaving them dependent on decisions made elsewhere. From a One Health standpoint, the authors argue, this exclusion of local knowledge undermines the community participation that integrated management requires.

The study’s recommendations are correspondingly structural rather than purely technical. The researchers call for policy revision, community co-management of hippopotamus populations, training of local eco-guards, fair compensation schemes for losses, and stronger coordination among health, veterinary and conservation services. They propose community-based monitoring committees that bring together health workers, veterinarians, customary authorities and conservation officers, alongside targeted training on zoonotic risks, injury prevention and trauma management, and participatory land-use planning that increases separation between farms, settlements and intense hippopotamus activity zones. Because agricultural fields near water points form recognized One Health hotspots globally, the authors argue that conservation policy which ignores water quality, wound infections and psychosocial stress will fail on its own terms.

Ultimately, the researchers conclude that the conflict in the Ruzizi Plain is not merely an ecological or agricultural problem but a manifestation of broader socio-political, health and environmental challenges. They are candid about the limits of their evidence: all findings on zoonotic exposure, water contamination and health impacts reflect stakeholder perceptions, and no epidemiological or environmental measurements were taken. They recommend future quantitative work on hippopotamus populations, agricultural losses and health-risk mapping to build an evidence base for coexistence strategies. Until then, the study stands as a warning that when strict conservation law meets desperate livelihoods with no compensation, no participation and no alternatives, the result is a cycle of grief, resentment and retaliatory killing that endangers both the people of South Kivu and one of Africa’s most iconic semi-aquatic mammals.

The study, published in the International Journal of Anthropology and Ethnology, draws on six field visits between September 2024 and May 2026, thirty-five interviews, twenty-three household visits including five oral histories, direct observation, and a dense body of policy and administrative documents. Its lead author, Qingyuan Li, and co-author Yan Ma, both of the Chinese Academy of Social Sciences, set out to answer a deceptively simple question: how do formal rules, culturally embedded practices, and monitored ecological change actually shape one another on the ground? Their answer challenges the way co-management is usually evaluated, which tends to treat institutions as the mechanism, ecology as the outcome, and culture as decorative background.

Wuyishan is an unusually revealing place to ask such questions. It is the only one of China’s first five national parks that overlaps a UNESCO World Heritage property inscribed under both cultural and natural criteria. Taoist texts from the Tang dynasty classified the mountain as the Sixteenth Grotto-Heaven, a sacred site within a ranked geography of numinous peaks. Zhu Xi, the towering figure of Neo-Confucianism, wrote and lectured there for more than five decades, founding the Wuyi Jingshe academy in 1183. Tea has been cultivated, classified, and traded from the region for centuries, traveling Dutch East India Company routes to Europe as bohea and overland along the Great Tea Road to Russia. The Fujian section of the park today covers more than 1,000 square kilometers, nearly 80 percent of the park, contains 28 natural villages and 3,415 registered residents, and has 66.4 percent of its land collectively owned.

The researchers’ framework demands a strict evidentiary standard. A relationship counts as co-constitutive only when a documented governance episode shows reciprocal change across at least two domains: a change in one domain traceable to an alteration in the form, meaning, or consequences of another. Mere co-presence, broad coupling, or descriptive entanglement does not qualify. This distinction matters because it converts a fashionable metaphor into something that can be tested, and potentially falsified, in other protected areas.

The clearest co-constitutive episode in the dataset involves a forest easement in Aotou Village. Under China’s tripartite rights system for collective forest land, ownership stays with the village collective while the park administration acquires specified protection authority for a fixed contractual period. Intensive bamboo management had created tension between watershed protection and village livelihoods. When easement agreements restricted intensive use in exchange for compensation, villagers were initially suspicious. Their insistence on retaining collective ownership shaped how the agreement was designed and interpreted, while the park’s contractual clarity and reliable payments shaped what villagers were willing to accept. The decisive feedback was not an abstract indicator but something everyone could see: water running clear downstream again. As one villager put it, when the water cleared and the compensation arrived on time, people knew the arrangement could work. At the scale of the Fujian section, the 2025 annual report records bamboo-forest easements covering about 6,053 hectares.

Tea culture supplies the second movement of the argument. Local growers evaluate their product through shanchang, a place-based category linking mountain shape, rock and soil, shade, moisture, surrounding vegetation, and cultivation history to sensory quality. A related idiom describes ideal tea-forest structure as wearing a cap, belt, and shoes: forest retained on hilltops moderates exposure and runoff, vegetation along slopes slows erosion, and ground cover protects soil and tea roots. This is not folklore appended to agriculture; it is a compact local model of forest–tea ecology. A tea farmer in Tianxin Village explained that the famous rock rhyme and rock bone and floral fragrance of Wuyi tea come from the harmonious ecological environment of each shanchang, adding that the ecological environment is the community’s rice bowl. Yet the researchers are careful to note the limits of cultural logic alone: shared ecological knowledge does not automatically produce restraint when tea prices soar, which is precisely where formal institutions enter as complementary enforcement.

That complementarity is visible in the Yanzike ecological tea garden, a demonstration project that translates traditional forest–tea knowledge into a standardized agroecological model. Taller trees provide shade and regulate microclimates, soybeans and rapeseed serve as green manure, and tea varieties are matched to local conditions, reducing chemical fertilizers and pesticides. Photovoltaic pest-control lamps and displays of temperature, humidity, and particulate matter make environmental conditions visible to managers and visitors alike. An interviewee described the project as an application of traditional ecological wisdom in which traditional culture and modern science jointly construct a modern ecological tea garden. Cultural knowledge lends the intervention legitimacy; scientific and administrative resources make it transferable.

Ritual does similar work in public. The tea-offering and mountain-calling ritual, jicha hanshan, descends from Song-dynasty customs and a Yuan-era rite at the Imperial Tea Garden, where in 1332 officials erected a platform from which drums were beaten and calls made for tea buds to emerge around the solar term of Jingzhe. Today the practice is listed as municipal-level intangible cultural heritage and staged publicly at tea sites. A scenic-area official summarized its ecological ethic succinctly: to ask the mountains for a living, one must respect them. The researchers treat such public staging analytically rather than romantically, noting that heritage presentation recontextualizes ritual and introduces commercial incentives, but they conclude that ritual gives conservation a culturally grounded language through which ecological responsibility is communicated and made meaningful.

Ecology, in turn, feeds back into governance through two complementary channels. Administratively, the park’s 2025 monitoring program conducted six rounds of surface-water sampling at 33 locations using 24 parameters, established 44 soil-monitoring plots, and recorded eight newly identified taxa, bringing the cumulative total to 62. Forest coverage in the Fujian section stands at nearly 94 percent. Situated observation runs alongside: a Hongxing Village resident who combines a family rock-tea business with work as a forest ranger patrols daily with a partner, flies a drone, and uploads images through standardized reporting procedures. His terrain familiarity directs where monitoring attention goes, while the reporting system converts local observation into evidence that travels across administrative levels. The park-wide system comprises 80 forest rangers and 98 patrol grids. Compensation and employment close the loop: in 2025 the administration paid 21.85 million renminbi to owners of ecological public-welfare forests and collective rights holders, and employed 72 conservation personnel, 80 rangers, and 26 checkpoint staff. Residents’ tea-sector income was estimated at roughly 1.3 billion renminbi.

The authors are candid about asymmetry. Public agencies retain legal and spatial authority; communities influence how rules operate and how ecological outcomes are interpreted, not the formal allocation of power. Reciprocity does not imply consensus or harmony. But the comparative payoff is concrete. The framework identifies four enabling conditions for similar dynamics elsewhere: durable institutional channels for evaluation and revision, ecological knowledge embedded in livelihood practice, visible connections between ecological quality and livelihood or identity, and organizations capable of translating situated observations across administrative levels. Where those conditions hold, whether in pastoral Sanjiangyuan, in contractual parks modeled on the Makuleke case in South Africa, or in tribally co-managed Bears Ears, culture can function as a practical medium of governance rather than a heritage label. Where they do not, the Wuyishan configuration may simply fail to emerge. Either way, the study offers something rare in conservation scholarship: a testable account of how rules, meaning, and mountains make each other.
