The scale of the review is impressive. The researchers searched four major databases, PubMed, Scopus, Google Scholar and AGRICOLA, using carefully constructed Boolean search strings that combined terms for biodiversity conservation, ecosystem protection, human impacts, socio-economic development, poverty alleviation and sustainable development with geographic terms covering Africa and sub-Saharan Africa. That search identified 439 publications. After applying the rigorous four-step PRISMA process of identification, screening, eligibility and inclusion, only 36 studies survived the methodological gauntlet. Of those, roughly 64 percent focused on conservation initiatives themselves, including protected areas, community-based management and the human activities that threaten biodiversity, while the remaining 36 percent examined socio-economic outcomes such as ecosystem services, carbon sequestration, tourism and recreation. The narrow funnel is itself telling: far fewer studies than expected rigorously connect ecological data with economic outcomes, leaving policy-makers to navigate a landscape of fragmented evidence.

The theoretical backbone of the review rests on three frameworks that give the findings analytical teeth. The Sustainable Livelihoods Framework examines how conservation affects the five capitals that rural households depend on: natural, financial, human, social and physical. The Human-Environment Systems framework treats ecological health and human well-being as a single dynamic system, making trade-offs and synergies visible rather than hidden. The Capability Approach, rooted in human development thinking, asks whether biodiversity initiatives expand or constrain the freedoms and opportunities available to African communities. Together, these lenses shift the debate away from the tired framing of fences versus people, and toward a systems view in which conservation success and human prosperity are treated as coupled variables that rise or fall together.

The evidence for coupling is striking. In Tanzania’s Kihansi River Basin, the successful reintroduction of the Kihansi spray toad, a species once extinct in the wild, depended directly on involving local communities in natural resource management, demonstrating that inclusive governance can rescue even the most technically demanding conservation programmes. In East Africa, research on pastoralist-wildlife interactions found that coexistence can actually improve local livelihoods and incomes, countering the assumption that livestock and wildlife are always in conflict. Yet the same continent offers cautionary examples: in South Africa’s Kavango-Zambezi Transfrontier Conservation Area, interactions between people, livestock and wildlife drive disease transmission, including foot-and-mouth disease and trypanosomiasis, alongside fierce competition for grazing and water. In Tanzania’s Maasai Steppe, expanding agriculture and pastoralism are accelerating land-use change with significant consequences for biodiversity. The lesson is that context determines everything, and interventions imported without local adaptation routinely fail.

The threats catalogued in the review read like a diagnosis of a patient in intensive care. Rapid population growth and urbanisation are projected to consume between 11 and 33 million hectares of natural habitat globally by 2100, with African urban expansion running above the global average and fragmenting the corridors that large mammals need to survive. Agricultural expansion, from cotton cultivation in the Mid-Zambezi Valley to broad-scale cropland conversion in West Africa, destroys habitat while pesticides and monoculture farming degrade what remains. Industrial and domestic pollution has pushed toxic metal concentrations in some East African agro-ecosystems beyond FAO and WHO soil health limits, and poor urban waste management in South Africa and elsewhere drives respiratory and waterborne disease in low-income communities. Overexploitation compounds the pressure: overfishing depletes marine and freshwater stocks, charcoal burning and overharvesting strip woodlands, and poaching has devastated iconic species.

The poaching statistics are among the most dramatic in the entire review. Tanzania’s elephant population collapsed by 72 percent between 1977 and 1991, falling from roughly 203,000 animals to 57,334, with the heaviest losses concentrated in the Selous Game Reserve and Serengeti National Park. Black rhinos suffered similarly catastrophic declines. The review notes that trade bans under CITES, the Convention on International Trade in Endangered Species, have been a cornerstone of protection for four decades, but it also flags a worrying set of factors that sustain illegal trade: inelastic demand for ivory and rhino horn, a long trading history, ambiguous property rights, negative economic incentives and inadequate enforcement. Responses have included Tanzania’s nationwide Operation UHAI and the global ivory ban, and the review argues that future efforts should pair robust law enforcement with advanced technologies such as drones and AI-based monitoring.

Governance emerges as perhaps the single most decisive variable. In a study of 109 resource management areas, law enforcement was the key factor determining great ape survival, outweighing even the economic benefits of tourism or research. Weak governance, corruption and poor enforcement of conservation laws allow illegal activities to flourish, and armed conflict makes everything worse: during civil unrest, weakened conservation capacity opens the door to poaching, habitat destruction and wildlife trafficking, as the situation in the Democratic Republic of Congo’s Virunga National Park illustrates. Invasive alien species add another layer of biological stress, with South Africa’s Cape region contending with dozens of established invaders, from wattles and pines to Eastern grey squirrels, that alter fire regimes, water resources and even urban infrastructure. Climate change interacts synergistically with all of these drivers, shifting species distributions, stressing sub-Saharan fisheries and, in Tanzania, projected to shrink suitable habitat for three tsetse fly species by 12.9 to 23.1 percent by 2050, a change that doubles as a predictor of sleeping sickness hotspots.

Yet the review is emphatic that conservation, done well, pays. Healthy ecosystems deliver pollination, clean air, water purification, soil fertility, pest control, climate regulation, flood protection, tourism revenue, cultural value, genetic resources and fisheries. The numbers are concrete: afforestation could mitigate an estimated 4.9 gigatonnes of carbon dioxide per year by 2050 at a cost of about 200 US dollars per tonne, while Kenya’s Mukogodo dryland forest landscape stores a cumulative 682 tonnes of carbon per hectare in forest reserves and generates sequestration potential worth roughly 40 million US dollars annually. Ecotourism employment across Southern Africa has measurably lifted rural household incomes and improved community perceptions of conservation. National parks such as Kruger, Serengeti and Virunga anchor legal protection, scientific research and tourism economies simultaneously. The review’s schematic logic is straightforward: where biodiversity is depleted through overexploitation, communities lose nearly everything, from tourism income to pollination services; where it is managed wisely through parks, reserves, reforestation and ecotourism, benefits flow sustainably.

The path forward, according to the authors, demands integration rather than trade-offs. Their recommendations include strengthening collaborative conservation strategies across borders, adopting sustainable and pollinator-friendly agriculture, expanding protected areas, deepening community-based conservation with genuine financial incentives, and implementing targeted policies that support both ecological resilience and human well-being. Innovative financing, public-private partnerships and inclusive governance structures all feature prominently. The review is candid about its own limits: reliance on secondary data may miss local nuance, the continental scope smooths over country-specific ecological and political realities, and marine biodiversity, indigenous knowledge and industrialisation impacts remain under-researched. Future work, the authors argue, should prioritise long-term monitoring, interdisciplinary collaboration, scalable models and emerging tools such as artificial intelligence and remote sensing.

What makes this review resonate beyond academic circles is its refusal to treat Africa’s biodiversity as a luxury to be protected from Africans. The evidence assembled here shows that the continent’s wildlife, forests and fisheries are not obstacles to development but infrastructure for it, as fundamental as roads and power grids. When enforcement fails, when communities are excluded, when agriculture expands without ecological guardrails, both nature and livelihoods collapse together. When parks, people and policy align, as the Kihansi toad’s return and the carbon-rich forests of northern Kenya demonstrate, prosperity and biodiversity reinforce each other. For a continent whose ecosystems underpin economies from the Serengeti to the Zambezi, that insight may be the most valuable export of all.

The COVID-19 pandemic exposed just how fragile healthcare systems can be when a novel pathogen crosses from animals into people, and how far-reaching the socio-economic fallout of a global health crisis becomes. It also renewed international attention on the One Health approach, a framework that emphasises the interdependence of human, animal and environmental health and highlights the role of intact ecosystems in reducing the risk of future pandemics. For the Philippines, these linkages are especially urgent. Recent assessments show that the country, one of the world’s recognised megadiverse nations and a global biodiversity hotspot, faces a concerning conservation impediment. If current declines continue unchecked, the ecosystem services provided by threatened species will erode, and the risk of wildlife-associated disease transmission will rise in parallel. The authors frame pandemics not as random misfortunes but as ecological events shaped by human disruption of nature, a reframing they argue offers a stronger basis for integrating conservation, health security and sustainable development.

The scientific logic linking forest loss to disease is well established in the literature the authors draw upon. Deforestation, wildlife hunting and unsustainable consumption degrade habitats and shrink species populations, forcing wildlife into closer proximity with human settlements and domestic animals. Research on land-use change in Southeast Asia has shown that such intensified contact increases opportunities for pathogen spillover and the emergence of novel infectious diseases, with studies of rhinolophid bats demonstrating how the livestock revolution and expanding cropland raise the risk of zoonotic coronavirus transmission. Over the past two decades the Philippines has lost more than one million hectares of tree cover, disrupting the ecological barriers that previously minimised interactions between wildlife, livestock and humans. Climate change compounds the problem: rising temperatures and shifting land use push bats, rodents and birds toward agricultural areas and human habitation, while warmer, wetter conditions expand the habitats of disease vectors, fuelling outbreaks of malaria, dengue and other infections in both human and wildlife populations.

Despite this growing evidence, the Perspective finds that One Health remains poorly integrated into Philippine biodiversity policy and practice. An analysis of research trends from 2000 to 2025 shows that One Health-related themes, including pandemic preparedness, public health and disease emergence, have been markedly underrepresented in national research output, with a notable increase only after the COVID-19 pandemic. Biodiversity-related studies remain considerably fewer than those focused on diseases and public health. The gap is especially striking for bats, which serve as natural reservoirs for a disproportionate number of zoonotic pathogens: fewer than 30 percent of bat species have been examined in disease-related studies, and both taxonomic and disease-type coverage across the order remain critically limited. Perhaps most tellingly, the Philippines is one of the Southeast Asian nations still lacking a national One Health Strategy, even as the region is recognised as a hotspot for emerging animal and human infectious diseases with potential for global spread.

The authors argue that this gap represents a missed opportunity to address the ecological drivers of disease emergence before they escalate into health and societal crises. Citing the Berlin Principles on One Health, which reaffirm the interdependence of human, animal and ecosystem health with economic and socio-political systems, they describe biodiversity conservation and One Health as mutually reinforcing endeavours: protecting biodiversity sustains health, and promoting health security strengthens environmental protection. Integrating One Health principles into conservation functions as a nature-based intervention and a preventive health strategy, helping to avert disease emergence while simultaneously protecting species. Shielding wildlife habitats from overexploitation minimises spillover risks to people and livestock, and curbing illegal wildlife trade conserves threatened species while reducing zoonotic risks associated with wildlife handling and consumption. The approach, they stress, should not be confined to disease surveillance but extended to actively safeguarding the wildlife and natural systems that sustain all life.

One persistent obstacle is institutional fragmentation. Biodiversity monitoring and disease surveillance in the Philippines largely operate independently, with the conservation and public health sectors rarely coordinating their efforts in a sustained manner. Agencies responsible for the environment, health and agriculture often work in isolation, producing fractured responses to deeply interrelated problems. The authors propose integrating these systems through coordinated monitoring of wildlife, livestock and human health across biodiversity-rich landscapes, which would enable early detection of both ecological tipping points and emerging infectious threats. They also recommend a dedicated One Health or Zoonotic Disease Unit with clear authority, adequate staffing and a defined budget, alongside a unified One Health-Biodiversity Fund built through interagency collaboration among the departments of health, environment, agriculture and science and technology, with investments distributed across capacity building, surveillance and early detection, open data sharing, prevention, and education.

Wildlife use presents one of the most delicate dimensions of the challenge. Hunting remains vital for the survival and socio-cultural heritage of rural and Indigenous communities, yet unregulated hunting has become a major driver of species decline in tropical forests. Large-bodied mammals and birds, including fruit bats, flying foxes, pangolins, wild pigs, civets and hornbills, are targeted for bushmeat, medicine and the exotic pet trade, creating interfaces where pathogens can cross species barriers when infected animals are handled or sold without safeguards. The authors do not call for an outright ban. Instead, they point to Republic Act No. 9147, the Wildlife Resources Conservation and Protection Act of 2001, which permits Indigenous Peoples to hunt wildlife for traditional subsistence rather than commercial trade, supported by the Indigenous Peoples’ Rights Act. The path forward, they argue, lies in health education, disease surveillance and wildlife monitoring in hunting areas, safe hunting zones, enforced quotas and alternative sources of protein and livelihood developed in genuine partnership with local communities.

Community engagement emerges throughout the paper as a prerequisite rather than an add-on. One Health approaches that centre local communities build environmental stewardship alongside health risk awareness, and link conservation to livelihood programmes such as community forestry, agroforestry and ecotourism, reducing dependency on wildlife exploitation and the frequency of human-wildlife conflict. Community-based forest management has been shown to reduce poverty incidence, easing pressure on agricultural expansion and limiting conflict at the wildlife-human interface. Indigenous and local communities bring generational knowledge of sustainable resource use that no external programme can replicate, and their meaningful inclusion in conservation planning, monitoring and decision-making is what makes One Health workable in practice. Expanding primary health clinics in remote, underserved areas bordering wildlife habitats, amplifying veterinary services in high-risk zones, and training protected area managers, rural health workers and community members to identify and report zoonotic risks would further anchor the approach on the ground.

Data infrastructure is another cornerstone. Effective conservation and zoonotic risk assessment depend on robust, open and FAIR, findable, accessible, interoperable and reusable, biodiversity data, such as those mobilised through the Global Biodiversity Information Facility. Integrating biodiversity information with health systems allows governments to identify overlaps between species persistence and disease vulnerability and to build early warning systems that fuse environmental and epidemiological data. Yet much Philippine biodiversity data remains poorly mobilised, and accessible zoonotic disease information is scarce: the global repository ZOVER holds only 24 records for Philippine bats, covering just seven of the country’s 78 bat species, and 19 records for ticks. The authors call for systematic wildlife disease surveillance, platforms for predicting high-risk species and areas, and strengthened university networks such as the Philippine One Health University Network, or PhilOHUN, to advance coordinated research regionally.

Ultimately, the Perspective reframes the extinction crisis as a public health, economic and ecological resilience concern. In a megadiverse country where habitat loss, wildlife trade, agricultural expansion, urbanisation and climate change overlap, biodiversity decline signals the weakening of the very systems that regulate disease transmission, support food and water security, sustain livelihoods and buffer communities from environmental shocks. The authors urge that One Health be embedded in national biodiversity and climate plans, supported by a national One Health council, interdisciplinary university programmes and biodiversity-health observatories, and adapted to the country’s institutional capacity and socio-ecological context. Poverty, inequality and limited resources make implementation difficult, but the alternative, responding to the next pandemic after it emerges, is far costlier. Conservation, they conclude, should become the foundation for a healthier Philippine society, in which ecosystem protection contributes directly to human well-being, animal health and environmental security for generations to come.
