Community-based conservation can support livelihoods and biodiversity, while
reinforcing local and Indigenous values, cultures, and institutions. Its delivery
can help address cross-cutting global challenges, such as climate change,
conservation, poverty, and food security. Therefore, understanding trends in
community-based conservation is pertinent to setting and implementing global
goals. We undertook a horizon scan to prioritize 15 emerging threats and oppor-
tunities expected to impact the future effectiveness of community-based con-
servation. Topics relate to global biodiversity policy; human rights; shifting
human geography; inclusion, diversity, equity, and access; conservation finance
and income; and economic reforms. Our findings offer guidance on strengthen-
ing community-based conservation to achieve global environmental and devel-
opment goals.
Motivations for a horizon scan on community-based conservation
Community-based conservation strives to integrate culturally sensitive socioeconomic develop-
ment with nature conservation to catalyze benefits for both people and nature. It aims to foster
stewardship of local ecosystems and biodiversity by enabling, championing, and elevating local
and collaborative governance systems and management practices [1–3]. The discourse on
community-based conservation has evolved to embrace localvalue systems and knowledge, de-
colonize conservation, support human well-being, and ensure the equitable distribution of bene-
fits and costs from conservation [4,5]. The practice of community-based conservation can either
be grassroots driven or implemented top-down, for example, via government directives or poli-
cies of the funding institution [2].
Effective implementation is dependent on delivery mechanisms, community characteristics, the
wider socioeconomic and political context [6], and proactive adaptation [7]. Outcomes can be
mixed, with initiatives prone to negative social outcomes when local world views are ignored or
resource management rights not effectively devolved [8]. Critiques highlight that existing legisla-
tion around natural resource management and an overemphasis on economic benefits under-
value cultural connections with place, commodify nature, and create economic competition
Highlights
The intertwined, global issues of climate
change, rapid biodiversity loss, and fail-
ure to eradicate poverty present a
wicked problem; they need to be ad-
dressed jointly, because each has impli-
cations for communities on the ground,
and one can fuel another.
For decades, community-based con-
servation has tried to tackle these
inter-related challenges with mixed
success and, at times, counter-
productive results, but has arisen as
a promising and popular approach
on global agendas.
We undertook a horizon scan on
community-based conservation and
identified 15 topics that offer opportuni-
ties to yield positive change for people
and the planet. The analysis also pro-
vides insights into pitfalls to avoid in
achieving 2030 global policy targets.

and associated decision inequities, even violence, ultimately disenfranchising rather than
empowering communities [4,7,9,10]. Community rights remain limited in many regions; nonethe-
less, community-based conservation has proven resilient, innovative, and continues to spread
[7,11]. The total land area legally recognized as under the direction of Indigenous peoples
and local community (IP&LC, see Glossary) is almost as large as that in protected areas
owned and managed by governments [12]. Moreover, territories under Indigenous stewardship
either legally or de facto cover more than a quarter of the planet’s land area and encompass
many biodiversity hotspots and ecologically intact ecosystems [12,13].
Thus, community-based conservation can contribute to policy developments and influence
legislation in three inextricably linked and worsening global predicaments: climate change, bio-
diversity loss, and the broader economic and social dimensions of the United Nations (UN)
Sustainable Development Goals (SDGs). Against a reality of unfavorable temperature tra-
jectories, Parties to the UN Framework Convention on Climate Change (UNFCCC) are
struggling to develop mechanisms to implement the Paris Agreement’s1.5°Ctargetfor
global warming [14]. Given the biodiversity crisis [15], Parties to the Convention on Biologi-
cal Diversity (CBD) have concluded protracted negotiations for the Kunming–Montreal
Global Biodiversity Framework (GBF [16]). Halfway through the implementation timeframe
for reaching the 2030 SDGs, progress is in jeopardy considering intersecting impacts from co-
ronavirus disease 2019 (COVID-19), the largest number of violent conflicts since World War II,
and climate change [17].
Community-based conservation can not only support, but also be significantly impacted by these
multilateral policy instruments. Therefore, we implemented a horizon scan in 2021 to understand
threats and opportunities expected to hinder or facilitate community-based conservation effec-
tiveness within the coming 10–15 years. Horizon scanning is a foresight technique for detecting
early signals of future change (as opposed to identifying past or current trends). The technique
gathers, organizes, and prioritizes new and existing evidence of emerging threats and opportuni-
ties in a structured and transparent way, using diverse information sources [18]. This supports
better coordination of resources, responsive policy, and on-the-ground action to pursue oppor-
tunities early and mitigate threats before they fully materialize [19].
Our process for gathering and prioritizing threats and opportunities in community-based conser-
vation sought to maximize globally representative ideas (Box 1). A three-person facilitation team
coordinated the systematic, stepwise consensus-building process [20] by which collaborators
analyzed and evolved ideas gathered via an online global survey (see Figure I in Box 2).
Previous environmentally focused horizon scans have informed policy, funding, and decision-
making [21]. By highlighting upcoming risks and opportunities in community-based conservation
for global policy and local grassroots audiences alike, we aim to encourage proactive strategies
and actions to safeguard biodiversity and enhance human well-being.
The top 15 emerging topics in community-based conservation
The prioritized topics fall into six broad themes related to: (i) global biodiversity policy; (ii) human
and community rights; (iii) shifting human geography; (iv) inclusion, diversity, equity, and access;
(v) conservation finance and income; and (vi) economic reforms (Figure 1). Many could exert either
negative or positive effects on community-based conservation, as evident in the brief descriptions
that follow (for further detail and a link to longer descriptions, see SM4 in the supplemental infor-
mation online). Examples in Table 1 illustrate how each topic may entail implications for conserva-
tion actors at local to global scales.

Global target to conserve 30% of Earth by 2030
Target 3 of the GBF aims to conserve 30% of the planet by 2030 while ensuring equitable gover-
nance, respecting IP&LC rights, and accommodating genuinely conservation-compatible sus-
tainable use [16]. This target could expand area-based conservation beyond conventional
protected area management and governance categories to recognize, learn from, include, and
foster other effective area-based conservation measures (OECMs) [26]. Conducive to
community-based conservation and IP&LC stewardship, such measures could redefine effec-
tiveness and create opportunities at scale [26], while helping to reinforce IP&LC rights. Although
the wording of this target tries to guard against top-down, fortress-style conservation, it may still
drive such outcomes to the detriment of IP&LCs and community-based conservation, depending
on how the GBF is implemented within national political and policy contexts.
Global ecosystem restoration commitments
The UN Decade on Ecosystem Restoration and the US$12 billion Global Forest Finance
Pledge at UNFCCC in 2021 have renewed global commitments to restore nature [14,27]. More-
over, UNFCCC now recognizes the centrality of ecosystem restoration for climate-change mitiga-
tion and adaptation [14]. Such high-level commitments risk encouraging large, unsustainable
initiatives that may help carbon capture, but excuse continued emissions, harm biodiversity,
and/or exclude local communities from decision-making [28–30]. Conversely, these commit-
ments can help communities (re)build resilient social–ecological systems if they embrace the
rights and autonomy of IP&LCs, Indigenous and traditional knowledge (ITK), adaptive man-
agement, and, as encouraged by target 2 of the GBF, focus on ecological integrity and connec-
tivity alongside ecosystem services and functions [16].
Box 1. Ensuring globally representative input and perspectives
Diverse inputs and perspectives are critical to gaining a comprehensive overview; people who think differently (for
which demographic, geographic, and occupational diversity serve as good proxies [22,23]) are thought to maximize
collective wisdom and objectivity [24]. Many horizon scans elicit inputs primarily from an invited group of ‘experts’.
However, who and what defines an expert is contentious, and poses the risk that certain worldviews dominate. Some
recent scans have mitigated this by (remotely) soliciting initial ideas from as many different contributors as possible to
capture diverse global views [25].
The horizon scan presented here took a two-pronged approach. First, it was guided by a culturally diverse steering
committee and working group (the ‘collaborators’) from 24 nations in South, Central, and North America, Southern,
Central, and Northern Europe, West, Central, East, and Southern Africa, Western, South, and Southeast Asia,
Australia, and the Pacific Islands. The group purposefully comprised approximately equal numbers of women and
men at different career stages with varied disciplinary ba ckgrounds (plant, animal, and marine biology, natural resource
management, environmental science, environmental policy, social and cultural anthropology, human geography,
history, rural and sustainable development), diverse geographic and ecosystem expertise (marine, fres hwater, and ter-
restrial systems, tropical to polar, and across all continents) and distinct roles across community-based conservation
(research, practice, policy, and funding).
Second, it used an open online global survey (see SM1 in the supplemental information online) to elicit ideas on emerging
threats and opportunities in community-based conservation. The online survey was created in nine languages (Arabic, tra-
ditional and simplified Chinese, English, French, German, Hindi, Portuguese, and Spanish), posted on 20 online media fo-
rums (subscription lists, websites, etc.), and directly emailed to at least 2189 people worldwide with a known or inferred
interest in community-based conservation. Recipients were encouraged to share the survey with others. Participants were
asked about: (i) their experience with community-based conservation and vision for success; (ii) observed and anticipated
impacts of the COVID-19 pandemic on community-based conservation efforts; and (iii) threats and opportunities they think
might hinder or facilitate effective community-based conservation within the next 15 years. Responses, collected from
March through May 2021, were anonymous, but respondents could choose to provide a name or organization for public
acknowledgement of participation (see SM2 in the supplemental information online). Responses were encouraged from
both individuals and groups to, for example, overcome language or literacy barriers by one person facilitating input from
team or community members.

Increased recognition of Indigenous and community rights
Growing emphasis on Indigenous, traditional, and community rights in global environmental pol-
icy [31], as exemplified by the US$1.7 billion pledge for tenure rights at the 2021 UNFCCC [32],
aspires to undo historic injustices and recognize the value of IP&LC knowledge and practices
in conservation [33]. Likely to further influence funding, legislation, and national policies, it may
foster improved environmental justice, given increased mapping of IP&LC rights [34] and possible
reinforcement by OECMs. This should increase recognition and support of community-based
conservation efforts. However, rights without resources are insufficient [35] and can be
undermined by conflict or the widespread rise of authoritarianism [36].
Growing violence against environmental human rights defenders
Threats and violence against environmental human rights defenders are rising, with record
numbers of murders and attacks in 2020 [37]. Increased attention from donors, international
fora, multilateral policy, media, and the public provides momentum to better integrate conser-
vation and human rights efforts. Security concerns can thwart community-based conservation
efforts. Existing mechanisms within the UN and EU, and pioneering Latin American legislation,
such as the Escazú Agreement [38], have the potential to mitigate against violations
associated with large extractive industries and conservation elites, but must be implemented
effectively.
Unpredictable and irregular human migration
More people than ever before were displaced by conflict, violence, and natural disasters in
2020–2022 [39]. Climate-induced disasters may displace up to 1 billion by 2050, with the
poorest disproportionately vulnerable [40]. Mobility can physically create space for conserva-
tion or reinvigorate talent pools by diversifying perspectives and experiences, potentially
Glossary
Black, Indigenous, and people of
color (BIPOC): term used to
acknowledge solidarity among, but also
differences in, the injustices faced by
various marginalized groups.
Buen Vivir:a departure from the
modern development narrative toward a
more biocentric, relational, and collective
understanding of well-being, where the
subject ofwell-being is not the individual,
but their interrelationship with their
cultural–natural environment.
Climate-smart approaches (CSA) to
agriculture, fisheries, and
aquaculture: actions to transform food
systems toward sustainable and climate
resilien t practic es, across agriculture,
commercial, and artisanal fisheries, and
aquaculture. Objectives encompass
sustainably increasing productivity and
incomes; adapting and building
resilience to climate change impactsand
variabilities; and reducing or removing
greenhouse gas emissions during
harvest, production, and the entire value
chain.
Conservation basic income: novel
biodiversity conservation funding
strategy that goes beyond conventional
market-based instruments.
Convention on Biological Diversity
(CBD): in force since 1993, the CBD
has three main objectives: ‘conservation
of biological diversity; sustainable use of
the compo nents of biological diversity;
fair and equitable sharing of the benefits
arising out of the utilization of genetic
resources’. This recognizes that
biological diversity is about not only
plants, animals, microorganisms and
their ecosystems, but also people and
our need for food security, medicine,
fresh air and water, shelter, and a clean
and healthy environment. The CBD
Conferenceof the Parties (CoP) governs
the Convention and advances its
implementation through decisions made
at periodic meetings.
Convivial conservation: convivial
(literally: ‘living with’)conservationoffers
a new and integrated approach to
understanding and practicing
environmental conservation.
Doughnut economics: informed by
ecological, feminist, institutional,
behavioral, and complexity economics,
doughnut economics is centred on
progression toward an economy with a
strong social foundation and an
unbroken ecological ceiling for the
sustainability of humanity.
Box 2. Gathering and prioritization ideas on threats and opportunities
The process for identifying priority topics followed methods similar to other horizon scans in conservation (e.g., [21,25]) with
the distinction that initial ideas were elicited via a global, open online survey, where participation was not limited to specific
invitees (Figure I). In total, 1175 people (555 individuals and 36 groups, which self-reported to encompass another 620 indi-
vidual respondents) submitted suggestions regarding threatsand opportunities emerging in community-basedconservation.
These respondents originated in 107 nations, including Indigenous nations, and resided in 109 countries. They performed a
variety of non-mutually exclusive roles in community-based conservation (48% research, 48% practice, 17% policy, 12%
funding, 10% local governance, and 10% other) for initiatives in diverse settings (69% terrestrial, 68% rural, 29% marine,
20% freshwater, 10% urban, and 0.5% other) across all global regions. Most had 7 or more years of experience in
community-based conservation (8% <1 year, 12% 1–3 years, 17% 4–6 years, 18% 7–10 years, 13% 11–15 years, 32%
>15 years; see SM2 in the supplemental information online). More respondents identified as male (58%) than female
(41%); 1% chose ‘other’gender identification or preferred not to answer. Their knowledge backgrounds ranged from gov-
ernment, protected area management, and biological sciences to farming, forestry, Indigenous and traditional ecological
knowledge, anthropology, law, business, education, political science, and tourism. Jointly, these participants submitted
ideas for 1483 threats and 1044 opportunities.
A total of 39 collaborators helped consolidate and prioritize these ideas by adapting the Delphi method [20], with at least 14
collaborators actively contributing at each step. The process involved synthesis, shortlisting, in-depth investigation, itera-
tive rounds of debate, and anonymous ranking to identify the top 15 emerging topics expected to shape the future of com-
munity-based conservation (Figure I). Coordinators grouped submitted ideas into 261 topics. Collaborators then scored
these on a 0–100 scale for novelty, plausibility, impact, pervasiveness, and horizon scan ‘worthiness’, which combines
the prior four characteristics via fuzzy logic (further details in SM2 in the supplemental information online). Mean ‘worthi-
ness’scores (raw and transformed into z-scores to reflect that not all collaborators used the full 0–100 value range) served
to identify a shortlist (Box 3). Collaborators then researched shortlisted topics to substantiate or dispute horizon scan ‘wor-
thiness’in a first round of debate, followed by once more assigning ‘worthiness’scores, another round of debate, and fur-
ther scoring. Debates were held anonymously and asynchronously via an online facilitation platform. Contentious topics
with highly diverging scores were given particular attention to promote consensus.

Figure I. The steps and people involved in distilling future threats and opportunities proposed by survey
respondents into a priority list of topics deemed highly relevant to the effectiveness of community-based
conservation over the next 10–15 years.
Environmental human rights
defenders: the UN General Assembly
defines these as: ‘Individuals and groups
who, in their personal or professional
capacityand in a peaceful manner, strive
to protect and promote human rights
relating to the environment, including
water, air, land, flora and fauna’.
Environmental, social, and
governance ( ESG): three factors
increasingly considered in addition to
profits in business to assess corporate
sustainability and ethical impact, material
risks, and growth opportunities.
Escazú Agreement: a2021
agreement among Latin American and
Caribbean governments as the first
environmental treaty of the region, which
enshrines the right of every person,
present and future, to a healthy
environment and sustainable
development. It is the first global
agreement with provisions on
environmental human rights defenders,
substantiating the high risks faced by
advocates and activists.
Global Biodiversity Framework
(GBF): at CoP14 of the CBD, a decision
was made to adopt a comprehensive
and participatory process to create a
post-2020 GBF, moving the world
toward the 2050 Vision of ‘living in
harmony with nature’. This landmark
document was finalized and adopted at
CoP15 as the Kunming–Montreal GBF
in December 2022.
Global Forest Finance Pledge at
UNFCCC CoP26: at the UNFCCC
CoP26, 130+ leaders, representing
more than 90% of the world’sforests,
committed to collaboratively halting and
reversing deforestation and land
degradation by 2030. Pledges were
made by globalleaders, industry,NGOs,
and community groups; this included
US$12 billion for forest-related climate
finance between 2021 and 2025 from
12 countries collectively.
Indigenous and traditional
knowledge (ITK): knowledge–
practice–belief complex encompassing
Traditional Ecological Knowledge (TEK)
and Indigenous Knowledge (or Native
Science). TEK refers to the evolving
relationships between living beings
(including humans) and their environment,
culturally transmitted generation to
generation. Indigenous knowledge is the
local knowledge held by Indigenous
peoples or local knowledge unique to a
given culture or society. Indigenous
knowledge and TEK are inter-related, but
not necessarily the same, concepts.

facilitating community-based conservation. More typically, however, displacements perpetuate
conflict and environmental degradation, erode community cohesion, undermine resource-use
planning, dilute ITK, and weaken cultural connections to place and nature [41,42].

the coming 15 years, and their thematic grouping. There is an assumed connection between topics within the same
theme. Broken arrows represent a direct connection between topics acrossthemes; additional, subtler connections may exist.
Indigenous peoples and local
community (IP&LC): ethnic groups
(typically) descended from, and

a given area, as opposed to groups that
have more recently settled, occupied, or
colonized the area.
Offset: mechanism in which individuals
or organizations compensate for their
carbon emissions or biodiversity loss
they cause by financially supporting
carbon capture or biodiversity
conservation elsewhere.
Other effective area-based
conservation measures (OECMs):
the CBD at CoP14 defined this as ‘A
geographically defined area other than a
Protected Area, which is governed and
managed in ways that achieve positive
and sustained long-term outcomes for
the in-situ conservation of biodiversity,
with associated ecosystem functions
and services and where applicable,
cultural, spiritual, socio-economic, and
other locally relevant values’.
Paris Agreement: to achieve a
climate-neutral world by the mid-21st
century, this legally binding international
treaty aims to limit global warming to
1.5°C relative to preindustrial levels.
Sustainable Development Goals
(SDGs): adopted in 2015,the UN SDGs
are global development targets, set to
be achieved in all countries by 2030.
UN Decade on Ecosystem
Restoration: joint initiative (2021–2030)
of the UN Environment Program and the
Food and Agriculture Organization of the
UN calling for the global protection and
revival of ecosystems for the benefits of
people and nature.
UN Framework Convention on
Climate Change (UNFCCC): with
near-universal membership (197
Parties), the UNFCCC entered into force
in 1994 and is the parent treaty of the
2015 Paris Agreement and the 1997
Kyoto Protocol. It aims to stabilize
atmospheric greenhouse gas levels to
prevent dangerous human–climate
interactions, allow ecosystems to adapt
naturally, and enable sustainable
development.
Unbanked populations: people who
do not have an account at a physical or
online financial institution. About
1.4 billion adults, mostly in developing
economies,remained unbankedglobally
in 2021.

Power shifting toward local actors
Heightened global recognition of continued, historically rooted injustices offers momentum to re-
dress international, national, and local power imbalances and mismatched goals within conserva-
tion partnerships [43]. However, mistrust is deep-seated and can spark protests, tensions, and
violence between those with and without power [e.g., big, well-funded international nongovern-
mental organizations (NGOs) vs. local, volunteer-based civil society organizations] [9]. Anticipated
growth of marginalized voices in decision-making gives hope that fair, transparent, inclusive gov-
ernance will advance socially just and culturally sensitive conservation approaches, such as com-
munity-based conservation, that avoid elite capture of resulting benefits [35].
Co-creating knowledge across disciplines and cultures
COVID-19 and associated travel constraints highlighted the need for interdisciplinary knowledge
and greater reliance on local leadership and community expertise. Although not a new concept
[44], knowledge co-creation with local and Indigenous stakeholders, including women, is increas-
ingly valued, but still often underutilized and misunderstood in environmental decision-making
[45]. Renewed interest may advance efforts to respectfully interweave knowledge systems, sup-
port cultural revival, and recognize Indigenous and Global South researchers and local actors
[46], facilitating genuine community-based conservation. Risks include tokenism, misrepresenta-
tion, and continued discrimination.
Conservation finance for grassroots initiatives
There is growing interest in dispersing funds to local-level and IP&LC initiatives [47]. Funders, as
well as emerging markets and new financing mechanisms, such as carbon finance, biodiversity
credits, and debt-for-nature swaps, could be tailored to suit and reach grassroots organizations
([48], but see [49]). Combined with capacity building and strategic support, these could
strengthen community-based conservation by aligning decision-making with local level resources
[47]. However, given that grassroots access remains rare [50], top-down imposition of locally in-
appropriate conservation measures remains a risk.
Diversifying conservation-compatible livelihoods
The stark economic downturn since 2020 has highlighted the urgency of sustainably diversifying
income and livelihoods for community-based conservation [51]. Options for conservation compat-
ible livelihoods are expanding [52] given growing online connectivity [53], increased environmental
and social responsibility in businesses [54], investment in sustainable enterprises [55], and conser-
vation finance mechanisms (e.g., environmental impact bonds) [47] or basic income schemes [56].
Adaptation to local contexts and careful evaluation via developing interdisciplinary metrics, includ-
ing culturally based indicators [57], are key for proof-of-concept to encourage wider adoption.

Locally based climate-smart agriculture and fisheries
Climate-smart approaches (CSA) to agriculture, aquaculture, and fisheries, aimed at en-
hancing the sustainability and climate resiliency of food production systems [58,59], draw upon
not only ITK, but increasingly also remote sensing, robotics, and artificial intelligence [60,61].
An over-reliance on technological innovation can make CSA inaccessible or socially inappropri-
ate. Moreover, it may undermine possible co-benefits to community-based conservation, such
as revived application of ITK, reduced biodiversity impacts, and improved livelihood resilience
[61,62]. Therefore, continued rollout of CSA requires forward-thinking and inclusive policy, legis-
lation, and capacity-building tailored to diverse contexts and stakeholders.
Mobile finance augmenting economic potential
Continued growth in mobile financial services has overcome cost, geographic, and identity-
verification barriers to provide previously ‘unbanked’populations with basic transaction ac-
counts, savings, credit, and insurance, which they previously lacked access to [63]. Benefits for
community-based conservation include increased financial and market literacy, pay-as-you-go
access to critical services (e.g., health, education, and utilities), expanded business opportunities,
and improved financial resilience [64–66]. However, unequal, gender-biased access could
deepen the digital divide [67]. Moreover, digital transaction records raise concerns over privacy
and misuse by corporations (predatory advertising) or fraudsters [65].
Leveraging 'basic income'
The COVID-19 pandemic has accelerated implementation of cash transfers comparable to tem-
porary basic income [68–70]. Prior pilot schemes indicate that basic income improves health, ed-
ucation, and income-generating capacity [71,72]. A ‘conservation basic income’for
communities connected to areas of conservation interest could support the environmental and
socio-economic goals of community-based conservation by reducing reliance on resource ex-
traction, balancing opportunity costs, and empowering social innovation [56,72]. Conditions
(even implicit ones [73]), safeguards, financing, and complementary conservation measures re-
quire careful consideration.
Changes in tourism and travel patterns
Dramatically reduced tourism in 2020–2021 in light of COVID-19 highlighted the social and envi-
ronmental impacts of the sector, both positive (e.g., people’s presence deterring poachers or in-
come) and negative (e.g., garbage, disturbance, or unemployment causing overexploitation),
inspiring momentum for reform toward more purposeful, sustainable, and regenerative tourism
[74–76]. Community-based conservation initiatives might in future benefit from atypical tourism,
such as agritourism, cultural immersion, wellness stays, digital nomadism, and virtual tours
[76–78]. Nonetheless, avoiding heavy dependence on tourism-derived income is key to resilient
jobs and operational budgets, especially because concern over greenhouse gas emissions
may reshape travel [79].
Moving away from conventional economics
COVID-19-induced social and economic upheaval initially amplified calls for economic reform
[80], or at least green economic recovery. However, green growth may insufficiently mitigate cli-
mate and biodiversity crises unless social, ecological, and intergenerational outcomes are prom-
inent in evaluating wealth [81]. There are growing efforts to identify more comprehensive
indicators of well-being [57]. Community-based conservation, already pursuing holistic concep-
tions of what constitutes ‘wealth’, can both guide and benefit from wider adoption of transforma-
tive, sufficiency-focused frameworks, such as doughnut economics,convivial conservation,
and Buen Vivir, each of which take into account both environmental and human needs [82–85].

Trends in Ecology & Evolution, Month 2023, Vol. xx, No. xx 9
Strengthened corporate norms and standards
Private sector partnerships for community-based conservation initiatives may grow as regulators,
investors, and consumers pressure corporations to improve their environmental, social, and
governance (ESG) outcomes [55,86,87]. Environmental reporting increasingly includes biodi-
versity impacts [88,89], and efforts to standardize metrics will help minimize greenwashing [90],
but must allow for contextually tailored safeguards reflective of local sociocultural conditions.
Communities could benefit through fair pricing, provision of amenities, and conservation support
if corporate ESG efforts avoid large-scale, flawed offset projects that ignore local people and/or
biodiversity.
Shortlisted topics that did not make the top 15 are summarized in Box 3, alongside information on
how each group of topics (top 15, shortlist, and longlist) distinguished itself in terms of novelty,
plausibility, impact, and pervasiveness.
Horizon scanning insights
Implications for policy, funding, and management
The topics identified, and their emerging or future impacts on community-based conservation,
have diverse implications for current and potential future stakeholders. Depending on what
Box 3. Shortlisted topics
The following topics were shortlisted, investigated, and debated, but did not make the top priority list. When two topics
were deemed inter-related, they were considered both individually and jointly.
•Ideologies that clash with local realities restrict or divert available funding (e.g., when animal rights groups oppose all
consumptive use of wildlife).
•Impacts from the COVID-19 pandemic reinforce feedback cycles between poverty, biodiversity loss, conflict, and
disenfranchisement.
•Blanket trade regulations on wildlife and natural products hamper income opportunities for community-based conser-
vation initiatives.
•Ecological and socioeconomic implications of facilitating market expansion, digitally or otherwise, for sustainable prod-
ucts from community-based conservation initiatives.
•The digital divide widens as internet access and technological literacy innovates information sharing and engagement.
•Schemes to accrue conservation funds based on, for example, royalties for use of nature-based imagery, branding,
and marketing.
•Retargeting and reforming international cooperation and foreign aid to support conservation finance.
•Community-partnered, culturally appropriate, renewable and green energy technologies, such as floating photovoltaics.
•Capitalizing on synergies and complementarities of community-based conservation with emerging global social change
movements.
•Coordinated responses to, and impact tracing of, corrupt practices (including land grabbing) that affect communities.
•Pandemic mitigation measures and risk of zoonotic disease trans mission impede community-based conservation operations.
•Pandemic-induced awareness of zoonotic disease promoting conservation.
•Awareness of gender, gender identity, and their cultural context as critical considerations in conservation and development
interventions.
•Increased recognition of the concept and effectiveness of community-based conservation models motivating growing
implementation.
•Uniting individual and shared interests for social mobilization around collective goals, despite individualism.
•Increasing recognition of the rights of nature (e.g., when rivers are assigned legal personhood) and legal recourse for
environmental damage.
•Insecure land tenure and resource management rights at national and local levels.
Although selected among the original 261 topics based on horizon scan ‘worthiness’scores, shortlisted topics also
scored higher on novelty (Student’st-test = –8.24, d.f. = 1127, P<0.001) and stood out when novelty, plausibility, im-
pact, and pervasiveness scores were summarized as additive (Student’st-test = –3.89, d.f. = 1135, P<0.001) or
geometric means (Student’st-test = –4.96, d.f. = 1175, P<0.001). In turn, the top 15 topics scored higher than
these shortlisted topics in impact (Student’st-test = –3.39, d.f. = 635, P<0.001), pervasiveness (Student’st-test =
–3.33, d.f. = 631, P<0.001), additive (Student’st-test = –4.00, d.f. = 631, P<0.001), and geometric means (Student’s
t-test = –3.60, d.f. = 649, P<0.001).

trajectory each topic follows, outcomes for community-based conservation and global targets
under the CBD, UNFCCC, and SDGs could be detrimental or favorable. The foresight that this ho-
rizon scan offers regarding emerging threats and opportunities provides a powerful opportunity to
proactively address risks and promote actions that steer topics along a positive trajectory.
In the immediate, five of the top 15 topics have direct relevance to the Kunming–Montreal GBF
targets. The topics on global ecosystem restoration commitments and on conserving 30% of
Earth by 2030 offer insights relevant to GBF targets 2 and 3 on restoration and the global 30 ×
30 target, respectively. The topic on CSA relates to target 10 on sustainable agriculture; strength-
ened corporate norms and standards to topic 15 on improving the environmental and social per-
formance of businesses and financial institutions; and increased recognition of Indigenous and
community rights is relevant to topics 1 (spatial conservation planning), 3 (protecting 30% of
Earth), 5 (stemming overexploitation), 8 (minimizing climate change impacts), 9 (sustainable
use), and 21 (involvement through free, prior, and informed consent) [16].
Insights generated by the top 15 topics are also relevant well beyond multilateral biodiversity pol-
icies. Table 1 provides a sample of audiences for horizon scan findings. The diversity of audiences
emphasizes how unconventional stakeholders may become important participants in, or cham-
pions for, community-based conservation. For many conservation actors, organizations, such
as the International Sustainability Standards Board or the Global Impact Investing Network, are
unlikely to have previously come to mind as potential partners. We acknowledge that audiences
in Table 1 primarily reflect organizations acting at a broader than local scale, because many of the
top 15 topics relate to issues beyond the control of individual communities. Nonetheless, the
topics entail lessons pertinent to communities; collaborators are working on disseminating
grassroots-relevant insights via appropriate channels.
Synergies and conflicts between topics
Many of the top 15 topics share current or projected future linkages (Figure 1). Therefore, the tra-
jectory of one can affect others. For example, a solution to support conservation finance for
grassroots initiatives via tailored, accessible funding mechanisms could aid transparent and
grassroots-accountable implementation of ecosystem restoration commitments and SDGs. Sim-
ilarly, strengthened recognition of IP&LC rights means that, more than ever, conservation inter-
ventions of any kind are expected to carefully consider rights and social justice. This can
promote co-creation of knowledge across disciplines and cultures. It is also shaping policy instru-
ments, with, for example, the text for at least six of the 21 goals proposed for the GBF making
reference to recognition or, participation by, and rights for, Indigenous people.
Conversely, if recognition of IP&LC rights is hampered by the current era of global democratic roll-
back and growth in top-down-heavy national governance, any gains from decolonizing conserva-
tion and creating greater local and grassroots autonomy may also be lost, undermining the trend
of power shifting from global toward local actors.
Convergent findings
We are unaware of any prior horizon scans specifically on community-based conservation, but
recent scans in related fields independently (and unbeknown to our collaborators) highlighted
several topics shortlisted or prioritized here. For example, both our shortlist and the 2023 annual
horizon scan of global biological conservation issues[21] feature innovative, decentralized energy
solutions, such as power generation through floating solar panels or microhydro operated by In-
digenous peoples
i
. Our shortlisted topic on internet access and technological literacy made the
top list in a 2020 forest and forest livelihoods horizon scan [91]. A horizon scan on challenges
Trends in Ecology & Evolution OPEN ACCESS
Trends in Ecology & Evolution, Month 2023, Vol. xx, No. xx 11
and solutions for sustainable rangelands in Australia identified the need for diversifying livelihoods
and meaningful cultural knowledge exchange, both among our top 15 [92].
Such overlap lends credence to the valueof the horizon scanning process for detecting weak sig-
nals. At the same time, each horizon scan focuses on a specific context. Thus, discrepancies are
expected and highlight nuanced differences in the context-specific relevance of any signal.
Challenges and contentions
We defined novelty based on personal familiarity plus a sense of who else may have heard about
a topic. Collaborators struggled at times to balance novelty with the more familiar risk assessment
criteria of plausibility, impact, and pervasiveness, which can be particularly hard to judge for newly
emerging topics or those undergoing a step-change in relevance or impact. For that reason,
some of the most vigorous debates (and highest standard deviations in scores) centered on
topics least known to collaborators. Examples include leveraging ‘basic income’, which made
the top 15, and increasing recognition of the rights of nature, which did not. Notably, economic
and legal expertise, which might have reduced uncertainty on these topics, was under-repre-
sented in the collaboration. However, significant distinctions between long-listed, shortlisted,
and ultimately prioritized topics in the additive and geometric means across novelty, plausibility,
impact, and pervasiveness, suggest that collaborators managed to successfully capture all four
facets in their intuitive horizon scan ‘worthiness’scores.
Horizon scans can vary considerably in scope, scale, and complexity [93]. Although conservation
generally is an interdisciplinary field, community-based conservation is particularly multifaceted
given its goal of benefitting both nature and people and consequent position at the juncture of de-
velopment and conservation. This is reflected in the diverse nature of priority topics identified
(Figure 1), and undoubtedly added to the vigor of debate, with tensions perceived by some col-
laborators between topics on rights and social change versus topics focused on technical and
financial advances.
At times, discussions among collaborators were side-tracked by debates over whether identified
trends were good versus bad, when the ultimate goal was to highlight changes regardless of their
desirability. Similarly, questions arose over for whom or for what we were assessing impact, and
whether impacts on biodiversity outcomes were equal to impacts on people. Such conundrums
emphasize that conservation, and community-based conservation in particular, is inseparable
from ethical considerations for which there are no universally agreed norms [94,95].
Concluding remarks
In pursuing both biodiversity conservation and human well-being, community-based conserva-
tion embraces the perspective that economy, society, and the environment are nested rather
than intersecting spheres. Society cannot exist without the environment, and the economy rep-
resents a subset of social interactions [96,97]. It is this perspective that makes community-
based conservation a potentially powerful approach for addressing current global, intercon-
nected crises.
This horizon scan has yielded suggestions for how to strengthen community-based conservation
as an approach, given emerging opportunities and risks. Implementation may require additional
investigations (see Outstanding questions). Proof of widespread impact will only be seen if
community-based conservation approaches can be effectively scaled organizationally and geo-
graphically [2,98]. There is immense potential, especially if certain conditions take hold, such as
if support from private enterprise and ESG materializes with appropriate standards and
