26 of the estimated maximum 72 Javan rhino have been poached by two gangs in the last five years. Absolutely shocking news!
I am an ecologist, and I have been lucky to work with white rhino in Africa. This work has involved capturing rhino, dehorning and moving them – methods used to try to save rhino from poachers.
Poachers target these large, plant-eating mammals for the illegal trade in rhino horn, fuelled by demand from Asia, principally China and Vietnam, where the horn is perceived as a status symbol, a cure for illness and an aphrodisiac.
Poaching is the main threat to the African rhino, but it was not considered a risk for the critically endangered Javan rhino in Asia. So rare and difficult to detect are Javan rhino, which live in dense jungle, that it was thought poachers would not be able to find them.
However, recent testimony from poachers arrested in Indonesia has indicated that 26 of the estimated maximum 72 Javan rhino have been poached by two gangs in the last five years. That is shocking news.
This revelation turns a worrying situation into an emergency – and demands increased efforts to save the Javan rhino from extinction.
How many Javan rhino are there?
Indonesian police arrested 13 members of two poaching gangs who revealed the otherwise undetected loss of rhino from Ujung Kulon National Park, the home of the world’s only remaining Javan rhino population, on the island of Java in the Indonesian archipelago.
Javan rhino were once widespread in southeast Asia. The last one outside of Indonesia was poached in Vietnam in 2010.
The actual number of rhino killed by the poaching gangs cannot be verified. It’s possible that sources within the government or conservation teams are passing information to poachers.

While Indonesia harbours the greatest amount of rainforest in Asia, over 74 million hectares (three times the land area of the UK) have been lost in the past 50 years to palm oil extraction and paper mills.
Indonesia’s forest cover has fallen from 80% to less than 50% amid one of the fastest deforestation rates in the world. Pandeglang, the Javan region containing the national park, has lost nearly 10% of its rainforest since 2000.
All scientists know about the abundance of Javan rhino is gleaned from camera traps, remote cameras that are triggered to take photos by passing animals. The last government population estimate was released in 2019.
A report published in 2023 criticised this estimate because 18 of the rhino counted had not been detected by a camera trap for three years, and three of the rhino counted were known to be dead.
Saving the Javan rhino from extinction
Indonesian conservationists have focused on habitat loss as the leading threat to Javan rhino, as it deprives the species of breeding opportunities. Scattered across separate fragments of jungle, rhino are unlikely to find each other during the brief window when females are receptive to mating.
There is also evidence of inbreeding, exacerbated by there being more adult males than females. Some biologists have called for Javan rhino to be taken into captive breeding programmes.
With just 46 Javan rhino in the wild (perhaps even less), poaching could wipe out the species or reduce it to such a low number that low breeding success deals the final blow.
Ujung Kulon National Park is located on the western tip of Java. Achmad Soerio Hutomo/Flickr, CC BYSo, what now? It is likely that the Javan rhino cannot afford to lose any further animals to poaching, and vital that further poaching is prevented. The Indonesian government has now increased security in the national park with police and military combining forces.
Allowing forests to naturally regenerate and planting corridors of trees between jungle patches will help the remaining rhino find suitable habitat and each other. Conservationists have also called for cutting down trees in some locations to allow fresh, young trees with more accessible leaves to grow.
Research has also shown that removing an invasive palm boosts the availability of rhino food plants. Livestock must be excluded from the park too, as domestic cattle can transmit disease.
As far back as 1986, conservationists called for some rhino to be moved out of the park (perhaps to the neighbouring island of Sumatra). Splitting an already limited population is risky, but not establishing the safety net of at least one other population elsewhere is riskier still.
What if a tsunami hit the park? And the park may already be near capacity, as it is estimated to be able to support only 68 rhino.
Bringing Javan rhino into captivity and using reproductive technologies on stored eggs and sperm (techniques in development for the more common white rhino) may also need to be considered. Although, it is still possible that captive breeding may not be required: camera traps have photographed newborn Javan rhino, as well as adults, as recently as March 2024.

Indonesian Ministry of Environment and ForestryScientists don’t know much about Javan rhino biology. There have been few studies of wild rhino and only 22 have ever been kept in captivity, the last of which died more than 100 years ago. More research is needed to understand as much as possible about Javan rhino ecology and reproduction – in the wild and from museum specimens.
More effective habitat and wildlife conservation across Indonesia will benefit other Indonesian species, including the Sumatran tiger, Sumatran elephant, all three species of orangutan, and the Sumatran rhino (estimated population of 24-47, making it the world’s most endangered rhino).
If effective conservation action is not taken now, the remaining Javan rhino population will go the same way as that in Vietnam.

Protecting Peru’s Grasslands Vital for Spectacled Bears
Protecting Peru’s Grasslands Vital for Spectacled Bears | A recent study highlights the importance of conserving Peru’s high-altitude puna grasslands to support the foraging habits of the vulnerable Andean bear AKA Spectacled Bear. The research reveals that these bears prefer young bromeliad plants in specific grassland areas and tend to avoid regions impacted by livestock. Conservation efforts focusing on these habitats could enhance the bears’ survival prospects.

The Andean bear, also known as the spectacled bear due to distinctive facial markings, is native to the Andes Mountains and currently classified as vulnerable by the International Union for Conservation of Nature (IUCN). A study published on December 18, 2024, in PLOS ONE emphasizes the critical role of high-elevation puna grasslands in Peru for the species’ foraging activities.
Researchers conducted extensive surveys in and around Manu National Park, focusing on two bromeliad species: Puya leptostachya and Puya membranacea. They observed that Andean bears selectively foraged in approximately 16.7% of available bromeliad patches, showing a preference for young plants located on east-facing, steep slopes at the forest’s edge. Notably, the bears avoided areas with active livestock grazing but were found in regions where livestock had been absent for several decades, indicating a potential for habitat recovery and reoccupation by the bears.
The study suggests that the cessation of livestock grazing can lead to the restoration of puna grasslands, making them more suitable for Andean bears in a relatively short timeframe. This finding underscores the need for targeted conservation strategies that mitigate human disturbances, particularly livestock grazing, to preserve these essential habitats.
Lead author Nicholas Pilfold from the San Diego Zoo Wildlife Alliance stated, “Using the largest collection ever of field data on the feeding behavior of Andean bears in high elevation grasslands, we found that the bears actively selected for specific food resources within the grasslands, indicating that these areas are of nutritional importance to the bears.”
The findings advocate for conservation managers to prioritize the protection and restoration of high-altitude grasslands bordering cloud forests, considering the adverse impacts of livestock on these ecosystems. Implementing such measures is vital for the sustenance and recovery of Andean bear populations in Peru.

Tucuxi Sotalia fluviatilis
Tucuxi Sotalia fluviatilis
IUCN Red List Status: Endangered
Location: #Brazil, #Peru, #Colombia, #Ecuador
Found throughout the #Amazon and Solimões River systems, including major tributaries and large lakes. Their range spans lowland rainforest areas of Brazil, southeastern Colombia, eastern Ecuador, and southern Peru.
The #Tucuxi, a small freshwater #dolphin of #Peru, #Ecuador, #Colombia and #Brazil now faces a dire future. Once common throughout the Amazon River system, they are now listed as #Endangered due to accelerating population declines. Threats include drowning in fishing nets, deforestation, mercury poisoning from gold mining, #palmoil run-off, oil drilling, and dam construction. A shocking 97% decline was recorded over 23 years in a single Amazon reserve. Without urgent action, this elegant and playful river dolphin could vanish from South America’s waterways.

Share to BlueSky Share to TwitterAppearance & Behaviour
Tucuxis are often mistaken for their oceanic dolphin cousins due to their streamlined bodies, short beaks, and smooth, pale-to-dark grey skin. But these freshwater dolphins are wholly unique—adapted to life in winding river systems where water levels rise and fall dramatically with the seasons.
What sets them apart is their remarkable intelligence and tightly knit social groups. Tucuxis are playful and curious by nature. They leap from the water in graceful arcs, sometimes spinning mid-air.
The Tucuxi, sometimes called the ‘grey dolphin’ due to their uniform colouring, resembles a smaller oceanic dolphin, with a streamlined body and slender beak. Their colour varies from pale grey on the belly to darker grey or bluish-grey along the back.
They travel in small groups of two to six, displaying coordinated swimming patterns. In rare cases, they may form groups up to 26 individuals, particularly at river confluences. Known for their agility, they leap and spin in the water with a grace that belies their size. Tucuxis are particularly drawn to dynamic habitats like river junctions, where waters mix and fish gather.
Threats
- Widespread deforestation from palm oil plantations Palm oil plantations are rapidly expanding across the Amazon, clearing vast tracts of forest that stabilise riverbanks and filter water. This deforestation leads to increased sedimentation in rivers, altering flow patterns and reducing water clarity—conditions that directly disrupt the Tucuxi’s feeding and movement. Run-off from fertilisers and pesticides used in palm oil monocultures also poisons aquatic ecosystems, harming Tucuxis other Amazonian dolphin species and the fish they rely on.
- Toxic mercury pollution from gold mining Artisanal and illegal gold mining in the Amazon releases massive quantities of mercury into the water, contaminating fish and other aquatic organisms. Tucuxis, as top predators, ingest this mercury through their prey, which accumulates in their tissues and causes neurological damage, weakened immunity, and reproductive failure. Mercury exposure is one of the most insidious threats, as it persists in ecosystems long after mining has ceased.
- Incidental drowning in fishing nets Tucuxis are frequently caught and killed in gillnets and other fishing gear as bycatch. Tucuxis and other Amazonian dolphins often inhabit the same confluence zones and productive fishing grounds targeted by local communities, making entanglement almost inevitable. Many carcasses are never recovered, having either been discarded by fishers or lost to river currents, meaning actual mortality rates are likely far higher than reported.
- Deliberate hunting for use as fish bait Though illegal, Tucuxis continue to be targeted and killed in parts of Brazil, especially near the Mamirauá and Amana Reserves, where they are used as bait in the piracatinga (catfish) fishery. This brutal practice involves harpooning or netting dolphins and using their flesh to lure fish, often alongside the killing of Botos. Despite a national ban, weak enforcement and ongoing demand mean this threat persists in remote and lawless regions.
- Illegal fishing with explosives and toxins In certain areas, particularly in Brazil and Peru, fishers use home-made explosives and poisoned bait to stun or kill fish en masse. These destructive methods harm or kill Tucuxis who are attracted by the sudden appearance of dead or stunned prey. The concussive force of explosions and the ingestion of poisoned prey result in slow, agonising deaths for affected dolphins.
- Construction of hydroelectric dams Dams fragment Tucuxi populations by blocking their movement along river corridors, reducing access to feeding and breeding grounds. These projects alter seasonal water flow, raise water temperatures, and flood critical habitats—conditions that significantly disrupt dolphin ecology. Brazil alone has 74 operational dams in the Amazon basin, with over 400 more planned, posing a long-term existential threat to freshwater cetaceans.
- Run-off and contamination from palm oil, soy and meat agriculture In addition to habitat loss, palm oil and soy plantations along with cattle ranching generates enormous volumes of chemical-laden waste, which enters waterways and poisons aquatic life. This pollution affects Tucuxis both directly and indirectly—exposing them to harmful substances and killing off sensitive fish species. As plantations replace biodiverse forests, the ecosystem becomes less resilient, accelerating the decline of species like the Tucuxi.
- Bioaccumulation of heavy metals and industrial pollutants Tucuxis, like many river dolphins, suffer from exposure to persistent organic pollutants such as PCBs, DDT, and flame retardants, as well as heavy metals like lead and cadmium. These toxins accumulate in dolphin tissues over time, weakening their immune systems, interfering with reproduction, and making them more vulnerable to disease. Contaminants originate from industrial waste, agriculture, and mining, and are now widespread across the Amazon basin.
- Habitat fragmentation from infrastructure and oil development Roads, oil pipelines, and shipping corridors criss-cross many parts of the Tucuxi’s range, slicing through their habitat and increasing the risk of collisions with boats. These developments also bring noise pollution, which can interfere with echolocation and communication. Fragmentation leads to isolated subpopulations, reducing genetic diversity and making recovery more difficult.
Geographic Range
The Tucuxi inhabits the Amazon River basin, spanning: Brazil, Peru, Colombia, Ecuador These river dolphins occur as far west as southern Peru and eastern Ecuador, and as far north as southeastern Colombia. They are notably absent from Bolivia’s Beni/Mamoré system, the Orinoco basin, and upper reaches above major waterfalls or rapids.
Their range includes wide, deep rivers and lakes, avoiding turbulent rapids and shallow areas. Despite overlapping with the Amazon River Dolphin (Inia geoffrensis), Tucuxis do not enter flooded forest habitats and stay closer to main river channels.
Diet
Tucuxis feed on more than 28 species of small, schooling freshwater fish, including members of the characid, sciaenid, and siluriform families. During the dry season, fish are concentrated in shrinking waterways, making them easier to catch. In contrast, flooding season disperses prey into forested areas, beyond the Tucuxi’s reach. They prefer to feed at river junctions and along confluences, where nutrient-rich waters concentrate fish populations.
Mating and Reproduction
Little is known about their mating behaviours. However, individuals appear to remain within familiar ranges for many years, and females likely give birth to a single calf after a long gestation. Calves are dependent for an extended period, learning complex navigation and foraging skills in rapidly changing river systems. The estimated generation length is 15.6 years.
FAQs
How many Tucuxis are left in the wild?
There is no comprehensive global population estimate. However, surveys from 1994–2017 in Brazil’s Mamirauá Reserve show a 7.4% annual decline—amounting to a 97% drop over three generations (da Silva et al., 2020). If this trend reflects the wider Amazon basin, the species could be on the brink of collapse.
How long do Tucuxis live?
Exact lifespans are unknown, but based on reproductive data and life history modelling, their generation length is around 15.6 years (Taylor et al., 2007), suggesting natural lifespans of 30–40 years.
How are palm oil and gold mining affecting Tucuxis?
Out-of-control palm oil expansion results in massive deforestation and run-off, clogging rivers with sediment and toxic agrochemicals. Gold mining adds mercury into aquatic ecosystems, where it bioaccumulates in fish—Tucuxis’ main food source. These pollutants cause reproductive harm, neurological damage, and immune system failure in dolphins.
Do Tucuxis make good pets and should they be kept in zoos?
Absolutely not. Tucuxis are intelligent, wild animals. Keeping them in captivity is deeply cruel and has no conservation benefit. Wild capture destroys families and can devastate local populations. If you care about these dolphins, say no to the exotic pet trade and the cruel zoo trade.
What habitats do they prefer?
Research in Peru’s Pacaya-Samiria Reserve shows that Tucuxis prefer river confluences and wide channels, particularly during the dry season when fish density is higher (Belanger et al., 2022). Feeding activity is especially concentrated in areas where whitewater rivers meet blackwater tributaries, creating nutrient-rich hotspots.
Take Action!
The Tucuxi is vanishing before our eyes. To protect them:
• Boycott palm oil and gold products linked to Amazon destruction.
• Choose fish-free and vegan products to reduce pressure on river ecosystems.
• Support indigenous-led conservation across the Amazon.
• Campaign for a ban on destructive dams, and the end of illegal fishing.

Why Pangolins Are So Special
#Pangolins of #Africa and Asia are the world’s most trafficked animal. Tragically they are disappearing due to illegal poaching as well as habitat loss for agribusiness like #palmoil. They get their name from the Malay word pengguling, which translates to “rolling up” in reference to their balled-up protective pose when threatened. Pangolins play an essential part in ecosystem health, keeping insects in check with their highly sensitive tongues and sense of smell. These remarkable and critically endangered animals deserve a break from savage and cruel #poaching and palm oil #deforestation. Help them when you #BoycottPalmOil #Boycott4Wildlife
The remarkable #pangolin is named ‘pengguling’ in Malay. Looking like a #pokemon or a scaly #dragon 🐉 they rid ecosystems in #Africa and #Asia of excess insects. Help them survive, be #vegan and #Boycottpalmoil 🌴🚫 #Boycott4Wildlife @palmoildetect https://wp.me/pcFhgU-92l

Pangolins play a vital role in ecosystems by controlling insect populations, particularly ants and termites, which helps maintain ecological balance.
Pangolins are fascinating creatures known for their unique appearance and distinctive scales. They are mammals belonging to the order Pholidota and are native to Africa and Asia. Due to their primary diet of ants and termites, pangolins are often referred to as “scaly anteaters”.
The African pangolin species are dispersed throughout southern, western, central and east Africa.
Pangolins face rapid declines across Asia and Africa, with all eight species classified as vulnerable, endangered, or critically endangered. They are threatened by poaching and habitat loss, driven by the demand for their meat and scales.
Pangolins are the most trafficked wild mammal in the world. Their meat is considered a delicacy in Asia while their scales are also used in traditional medicines, fetching huge sums on the black market. As many as 8.5 million pangolins are estimated to have been removed from the wild in west and central Africa for the illegal trade between 2014 and 2021.
The trade route analysis of pangolin trafficking points to Lagos as the main connection point both domestically and worldwide, including south-east Asian countries. Malaysia, Laos and Singapore also serve as key transit countries for pangolin-scale shipments from Nigeria.
China and Vietnam are the main destinations for these illegal shipments.
I am a zoologist who’s passionate about the environment and biodiversity conservation. I am also the founder and chair of Pangolin Conservation Guild Nigeria. In my view, effective protection, law enforcement and changes in consumer behaviour are necessary to address the complex drivers of poaching and trafficking.
What makes pangolins special
Pangolins are interesting for a number of reasons.
Scales: Unlike any other mammals, they are covered with keratin scales. This adaptation is a defence against predators. The scales, made of the same material as human fingernails, provide armour-like protection as they curl into a ball when threatened, shielding their vulnerable underbelly. The scales can account for up to 20% of a pangolin’s total body weight. A pangolin’s scales are a reminder of the incredible diversity of adaptations in the natural world.
Habitats: Pangolins, as a group, are also adaptable to different environmental conditions. Their habitats include tropical forests, dry woodlands and savannahs. Some pangolin species, like the white-bellied, are adept climbers and spend much of their time in the canopy, foraging for insects among the branches. These arboreal habits provide them with both food and shelter, as well as protection from ground-dwelling predators. Other pangolin species, such as the ground pangolins, live on the forest floor or in grasslands. They may dig burrows underground where they retreat for rest and safety, particularly during the heat of the day or to escape potential threats.
Defence: The name “pangolin” originates from the Malay word pengguling, which translates to “rolling up”. They tuck in their head and limbs and curl into a tight ball when faced with danger, wrapping their body in a protective layer of overlapping scales. This has helped pangolins survive predators such as big cats, hyenas and humans.
Diet: Pangolins primarily feed on ants and termites, making them essential players in controlling insect populations within their ecosystems. They find the insects using their keen sense of smell and their tongues – which are often longer than their bodies. These long tongues are coated with sticky saliva, allowing them to probe deep into ant and termite nests to extract their prey. Their strong claws are also well-suited for tearing open insect nests and breaking through hard soil to uncover hidden prey. Pangolins’ diets play a crucial role in maintaining the health and stability of their environments.
Pangolins in Africa
In west and central Africa, the giant pangolin is distributed in a variety of habitats, including primary and secondary forests, swamp forests and wooded savannahs. Temminck’s pangolin (Smutsia temminckii) is the most widely distributed African pangolin, occurring mainly in southern and east Africa. The black-bellied pangolin (Phataginus tetradactyla) is an arboreal pangolin species, and occurs in west and central Africa. The white-bellied pangolin (Phataginus tricuspis) is the most frequently encountered pangolin in Africa. The white-bellied pangolin is found in north-central and south-western Nigeria.
White-bellied Pangolin Phataginus tricuspisIn Nigeria, pangolins are found in various habitats, including forests, savannahs and grasslands. Their distribution and abundance in Nigeria are uncertain, highlighting the need for further research and conservation efforts.
Lagos, Nigeria’s commercial capital, serves as a hub for the illegal trade of pangolins. It is a transit route to Cameroon and is involved in shipments of pangolins from sub-Saharan Africa to Asia. Cameroon is at the centre of wildlife trafficking in central Africa. It is both a source country of animal products as well as a transit route for contraband from neighbouring Republic of Congo, the Democratic Republic of Congo and the Central African Republic.
In 2022, Nigerian customs officials seized 1,613 tonnes of pangolin scales and arrested 14 people. In October 2023, Nigeria burned four tonnes of seized pangolin scales, valued at US$1.4 million. Officials said this was the first time they had publicly destroyed seized wildlife products to discourage illegal trafficking.
Why pangolin conservation is important
Pangolin conservation is crucial for several reasons.
Firstly, pangolins play a vital role in ecosystems by controlling insect populations, particularly ants and termites, which helps maintain ecological balance.
They also contribute to soil health through their digging behaviour, which aerates the soil and promotes nutrient cycling.
Moreover, pangolins are indicators of ecosystem health. Their presence or absence can reflect the overall well-being of their habitats. Protecting pangolins helps safeguard biodiversity and the integrity of their ecosystems.
They also have cultural and economic value in many regions, contributing to ecotourism.

Palm Oil Deforestation and Disease-Carrying Mosquitoes
Short version
A 2023 study published in Nature has found that cutting down rainforest to grow palm oil makes it easier for certain disease-carrying bugs like Aedes albopictus mosquitoes to thrive.
The study looks at how these changes in land use affect the local weather and environment, which in turn makes it easier for the mosquitoes to complete their life cycle.
Specifically, turning forests into palm oil plantations can increase the chances of these mosquitoes growing by about 11%, which drops to around 5% as the palm oil plants mature. This could lead to more frequent outbreaks of diseases carried by these mosquitoes.
Aedes albopictus is known to transmit pathogens and viruses, such as the Yellow Fever, Dengue Fever, Chikungunya fever and Usutu virus. The study suggests careful policy-making and planning is urgently needed to assess how we use land, balancing the need for palm oil farming.
There are strong inherent risks to public health from palm oil agriculture and vector-borne diseases. #Boycottpalmoil

Abstract
A major trade-off of land-use change is the potential for increased risk of infectious diseases, a.o. through impacting disease vector life-cycles. Evaluating the public health implications of land-use conversions requires spatially detailed modelling linking land-use to vector ecology. Here, we estimate the impact of deforestation for oil palm cultivation on the number of life-cycle completions of Aedes albopictus via its impact on local microclimates. We apply a recently developed mechanistic phenology model to a fine-scaled (50-m resolution) microclimate dataset that includes daily temperature, rainfall and evaporation. Results of this combined model indicate that the conversion from lowland rainforest to plantations increases suitability for A. albopictus development by 10.8%, moderated to 4.7% with oil palm growth to maturity. Deforestation followed by typical plantation planting-maturation-clearance-replanting cycles is predicted to create pulses of high development suitability. Our results highlight the need to explore sustainable land-use scenarios that resolve conflicts between agricultural and human health objectives.
Introduction
Agricultural development has an extensive impact on natural and socioeconomic systems worldwide1,2. The globally rising demand in versatile tropical crops, such as oil palm, has led to a rapid increase in agricultural exploitation in developing countries3,4. Although agricultural development can bring important economic benefits, it has well known implications for biodiversity and carbon storage especially in areas where agricultural land directly replaces pristine tropical rainforest5. Currently, however, the measurable health risks of different land-use types remain poorly evaluated and human health impacts are therefore rarely integrated into land-use decision making.
Infectious disease transmission is an important dimension of human health that can be affected by agricultural land-use change. Patz et al.6 proposed that changing landscapes could become ‘unhealthy landscapes’ because of numerous examples of land-use change being linked to infectious disease risks (e.g., Lyme disease, Nipah virus). Since then, numerous studies have linked agricultural land-use change to increased infectious disease incidence7,8,9,10. In a recent meta-analysis, Shah et al.11 found that exposure to agriculture on average almost doubled the risk of being infected by any pathogen, with the highest effect sizes being observed for tropical tree crop monocultures including oil palm (odds ratio (OR) = 3.25) and rubber (OR = 2.27).
One mechanism that could help explain such associations is a change in microclimatic conditions following the change in land cover, which may favour the development of disease vectors12,13. Ectothermic arthropod vectors are highly sensitive to changes in environmental temperature, which govern their metabolic rates and development, and therefore their fitness and population growth rates14,15. In addition, many disease vectors respond to changes in humidity and/or rainfall due to their aquatic life-stages, which require the availability of adequate water bodies for development15,16. The precise effects of climate on population abundance are nevertheless highly vector-specific.
The changes in microclimate associated with deforestation for agricultural expansion offer considerable potential to impact disease vector development. Forest canopies typically buffer against extremes in local temperature and humidity through interception, transformation and storage of solar radiation, leaf transpiration and altered airflow17. Landscapes in transition to tropical tree-based agriculture, such as rubber or oil palm plantations, often encompass a strong gradient in land-use intensity with many differences in vegetation cover, canopy height and community complexity. Both on a relatively small spatial and temporal scale, vegetation in these landscapes can range from 50 + meter high intact or selectively logged tropical rainforest, to clear-cut open land, to 10–20 m full-grown plantation trees, all with varying microclimatic features. Recently, Jucker et al.18 performed high-resolution modelling of microclimate in a transitioning oil palm landscape and showed that deforested areas and oil palm plantations experienced substantially higher daily temperatures and lower relative humidity compared with rainforest areas. Older plantations experienced lower temperatures and higher relative humidity than younger plantations, although they remained warmer and drier than the rainforest areas. Predicting how these microclimate differences might in turn impact mosquito development and thereby, potentially, vector-borne disease (VBD) risks, is essential to be able to direct both large- (i.e. deforestation) and small-scale (i.e. cultivation design) land-use policy decision making.
Multiple field and experimental studies have demonstrated that land-use change can accelerate disease vector development through altering microclimates19,20,21,22. Mechanistic models of vector development could be an important tool to translate these observational findings into predictions across different settings, and, eventually, into land-use policies23. By explicitly incorporating environment-development relationships, they are also useful in evaluating the complex interplay of different environmental variables, such as temperature and humidity. Multiple studies have, for instance, already assessed the complex effects of global climate change on local disease vector development using mechanistic models and have predicted an acceleration of disease vector development resulting in expanding as well as shifting global distributions in the coming decades24,25,26,27,28. Mechanistic modelling studies that incorporate the effects of land-use change are scarcer and are typically limited by lack of adequately fine-scaled datasets that can capture the microclimatic variation attributable to vegetation cover differences29,30.
Here, we extended a recently developed spatially explicit physiological development model for the mosquito Aedes aegypti28 to predict the impact of fine-scaled, tree cover-related changes in microclimate on the number of life cycle completions of the related arboviral disease vector Aedes albopictus. Detailed land-use and microclimate data from Malaysia18 was used to capture the impacts of tropical forest conversion to oil palm plantation on mosquito development at appropriate spatio-temporal scales31. A comprehensive representation of the interactions between microclimates and vector development is provided by evaluating the separate and combined effects of temperature and humidity. We use our results to infer the trajectories of mosquito population growth according to realistic land-use succession scenarios within an oil palm-agricultural landscape. With this study, we aim to determine to what extent a forest-to-plantation transition could enhance mosquito development as a result of changes in local temperature and humidity linked to land-use change. Our results have important implications for evaluating vector-borne disease risks of agricultural expansion.
Conclusions
We predict that microclimate change by deforestation for oil palm, which can occur in a mere months, could increase disease vector development suitability to an extent comparable to decades of global warming. Our model predicts that plantation maturation to higher vegetation cover moderates A. albopictus development rates, although suitability remains increased in lowland plantations compared to original forest areas. These results stress the importance of tropical forest protection and give directions for alternative oil palm plantation systems that minimize public health risks12,28.
