Researchers have launched a brand new e book that catalogs a whole bunch of plant species from Cambodia’s Prey Lang Wildlife Sanctuary which have identified medicinal makes use of.The e book attracts on the data of Indigenous communities who’ve discovered a use for these crops over the course of generations, and whose livelihoods and cultures are intently intertwined with the destiny of those species.The e book additionally serves to focus on the imperiled state of affairs of Prey Lang and its native species as deforestation by politically linked timber-trafficking networks continues to destroy huge swaths of this ostensibly protected space.“If the present traits of deforestation proceed,” the authors warn, “an immense physique of data about nature can be misplaced, lowering the resilience and flexibility of future generations.”
PHNOM PENH — “This e book gained’t cease deforestation, however it may possibly present what’s at stake, what we are going to lose if we lose Prey Lang,” stated Nerea Turreira-Garcia, assistant professor on the University of Copenhagen, on the Nov. 14 launch of Gifts from Nature, a e book she co-authored with Dimitris Argyriou, group engagement and know-how specialist at Forest & Peoples Organization.
The e book paperwork the wide selection of flora present in Cambodia’s Prey Lang Wildlife Sanctuary and a large number of makes use of that communities who stay in and across the forest have discovered for them.
Five years of fieldwork and 374 plant species later, what started in 2014 lastly blossomed into fruition in 2023 on the Preak Leap National Institute of Agriculture. Gifts from Nature goals to make accessible in each Khmer and English the findings from Indigenous-led analysis into the embattled Prey Lang, mainland Southeast Asia’s largest lowland evergreen rainforest.
“Lowland forests, corresponding to Prey Lang, are at larger danger of deforestation than mountain forests as they’re extra accessible to loggers and their vans,” Turreira-Garcia stated. “The significance of Prey Lang lies in its nice variety of forest sorts and plant species, a lot of that are endemic to the central plains of Cambodia, that means they are often discovered nowhere else, rendering Prey Lang a essential ecosystem.”
This ecosystem specifically has been the goal of unlawful loggers for years. Nearly 90,000 hectares (222,000 acres) of forest had been misplaced between 2002 and 2022, in line with Global Forest Watch knowledge, with greater than half of that — 48,740 hectares (120,440 acres) — misplaced since 2018, presenting a worrying pattern of unabated destruction in Prey Lang.

The roughly 490,000-hectare (1.21-million-acre) protected space has been one of the vital hotly contested forests in Cambodia, with the Prey Lang Community Network (PLCN) having mounted a fierce protection towards the politically linked timber-trafficking networks that plunder the forest’s beneficial bushes. This, in flip, led the federal government to crackdown on the PLCN, outlawing the grassroots group and banning it from patrolling the forests to guard the pure sources that its members rely on. There are an estimated 250,000 Indigenous Kuy individuals who stay in and round Prey Lang, in addition to a variety of ethnically Khmer communities.
It was from these communities that Turreira-Garcia and Argyriou discovered 20 specialists, a mixture of Kuy and Khmer residents of the 4 provinces that Prey Lang straddles, to assist doc and protect their Indigenous data of and makes use of for the forest’s bountiful flora.

Highlighting the potential medicinal and cultural worth of Prey Lang
“In the unique research, a complete of 630 makes use of had been recorded for the 374 crops and every plant had on common two makes use of, though many crops had extra,” stated Argyriou, who added that of the 374 crops, solely 279 may very well be recognized to the species degree and so Gifts from Nature solely paperwork these for which full info may very well be offered. Prey Lang’s inhabitants have discovered culinary, medicinal and ritual makes use of for these 279 species, in addition to sustainable development practices.
Of the 279 that Turreira-Garcia and Argyriou had been in a position to absolutely doc, simply 94 had been listed by the IUCN, out of which 20 are critically endangered, endangered, weak or close to threatened. The remaining 185 species stay unlisted by the IUCN, that means they haven’t been assessed and that there’s doubtless not sufficient knowledge to categorise their abundance or makes use of.
More than 1,000 samples had been despatched to 2 botanists who helped with the verification of knowledge offered by native specialists and the indexing of species. The e book builds on a 2017 research revealed by the authors, who famous that the translations from Kuy to Khmer after which to English took a substantial period of time.
Turreira-Garcia stated that whereas many books have been written on battle, poverty and politics in Cambodia, little has been written of the nation’s pure sources or those that rely on them, and fewer nonetheless draw so closely on native data.

“The researchers got here to our village and requested about these crops,” Hean Youn, a member of the PLCN who labored with the researchers, stated on the e book launch. “We understand how completely different flora can be utilized to deal with numerous sicknesses and illnesses, we all know this from our ancestors and we’re very joyful to share this data and our tales. We need them to be heard in order that extra individuals will be part of within the safety of the pure sources which are so vital to us.”
Youn detailed how his group lives alongside Prey Lang and is deeply depending on the forest for a variety of naturally occurring merchandise.
“We have to show others methods to use these conventional medicines, however we should be taught from our elders first,” he added.
In 2012, a research discovered that as a lot as 50% of the medication accredited for the reason that Eighties had been immediately or not directly created from pure merchandise, whereas 11% of the 252 medication listed as important medicines by the World Health Organization on the time had been solely derived from flowering crops. Turreira-Garcia and Argyriou warned that Prey Lang might home vital pure substances for future medicines, however the price of forest loss might imply new scientific discoveries might by no means come to mild.
“Traditional plant data is dynamic,” Turreira-Garcia stated. “New plant makes use of will emerge from new trial-and-error makes an attempt or from interpersonal and intercultural encounters, whereas some can be misplaced.”

Cambodian forest loss akin to ‘burning of a library’
This warning was underscored by Von Monin, affiliate professor on the Preak Leap National Institute of Agriculture and an adviser to the Ministry of Agriculture, Forestry and Fisheries. He famous that throughout Cambodia, there are as many as 8,000 plant species, with every native tree within the nation bearing an oblique worth of $3,700 per tree if every of its elements are used to their full potential.
But the variety and quantity of species present in Cambodia is shrinking together with its forest cowl, Monin stated. He cited official statistics exhibiting that forests lined greater than 13 million hectares (32 million acres) of Cambodia earlier than 1970, equal to greater than 73% of the nation’s land mass, however that this fell to 10 million hectares (25 million acres) by 1990 after which 8.7 million hectares (21 million acres) by 2016, leaving simply 48% of the nation forested.
Only 15.7% of Cambodia’s remaining forests had been discovered to be dense, evergreen, main forest by 2016, in contrast with 29.9% in research carried out previous to 1970, in line with Monin.
Much of those losses stem from the privatization of forested land, ostensibly underneath the guise of growth by way of financial land concessions (ELCs), though few advantages have been shared past the networks of patronage that had been awarded a lot of the nation’s greatest forests.

“During our fieldwork, we observed that in villages close to ELCs, individuals had worse dwelling requirements in comparison with the villages that had been nearer to Prey Lang,” Argyriou stated. “The forest brings abundance, and the businesses carry dependency on the capitalist system.”
Gifts from Nature is the primary try to doc a majority of the flora that exist inside Prey Lang and the reliance that largely Indigenous communities have on the forest as a direct outcome. But the data it compiles is, just like the forest, prone to being irrevocably misplaced.
“The e book exhibits that it is extremely related to make use of participatory strategies to herald the voice of native populations and Indigenous peoples in forest conservation and documentation of plant makes use of,” Turreira-Garcia stated, noting how a lot of the ecological data of those communities stays within the arms of the elders, who’re not often consulted in rural growth plans.
“During the final 5 years, two out of our 20 key informants have died,” she added. “More than half of them are above the age of 65, so the time to behave is now. We can examine the demise of an elder with the burning of a library about pure historical past — if youthful generations don’t be taught from their elders, vital environmental data can be misplaced.”

Deforestation driving Indigenous communities to destitution
As miners, loggers, concessionaires and smallholder farmers every go away their very own indelible mark on Prey Lang by clearing the forest for their very own ends, the affect is felt most keenly by the Indigenous communities, Argyriou stated.
“The lack of Prey Lang Wildlife Sanctuary could be disastrous at many interlinked ranges,” he stated, noting that selective logging and clear-cutting for plantations is bringing concerning the extinction of tree species corresponding to Dalbergia cochinchinensis (domestically generally known as krornhong), Dalbergia oliveri (neanghoun), and Cinnamomum cambodianum (tepproo).
C. cambodianum is a extremely valued tree utilized by native communities for development, in meals, for the remedy of post-partum ache and joint pains, and to terminate undesirable pregnancies. Both Turreira-Garcia and Argyriou cautioned that the medicinal makes use of listed in Gifts from Nature aren’t lab-tested and that the data introduced shouldn’t be thought of an alternative choice to skilled medical recommendation.

“As the scientific title Cinnamomum cambodianum suggests, the tree is endemic to Cambodia and is critically endangered. Hence, whether it is misplaced in Prey Lang and different Cambodian forests, it is going to disappear from Earth,” Argyriou stated. “Other threatened species embody bushes that belong to the Dipterocarp household. Locals use these bushes to faucet resin, which is commonly the one supply of earnings for the household. Without the resin bushes, already weak households might find yourself in additional excessive types of poverty.”
These bushes are sometimes focused by logging syndicates, robbing communities of an important supply of earnings.
The lack of entry to drugs, meals, firewood, timber and livelihoods sourced from the forest is coupled with the religious attachment that each Kuy and Khmer communities must the forest and the biodiversity it holds.
This, Argyriou stated, signifies that destroying the forest is tantamount to killing vital points of native tradition, however it additionally robs these communities of the power to be self-sufficient.
“If the present traits of deforestation proceed, native populations should drastically change their lifestyle that brings them away from their tradition,” he stated, noting that having to buy what they will presently discover at no cost will render many extra weak and poorer. “An immense physique of data about nature can be misplaced, lowering the resilience and flexibility of future generations.”
