Beyond the Numbers: What 25 + Years in Conservation Have Taught Me About Impact

 From protecting ecosystems and changing behaviors to rethinking how we measure success

For more than 25 + years, I have dedicated my professional life to conservation. I spent over two decades working with NGOs, primarily focused on protecting species, conserving ecosystems, and addressing the threats driving biodiversity loss. Over the last four years, my journey has taken me into the private sector, working in nature-based carbon projects, with a particular focus on community strategies.

Moving between these two worlds has given me a different perspective on a question that has followed me throughout my career: How do we really know that our conservation efforts are making a difference?

I have seen projects celebrate the number of people trained, workshops delivered, hectares covered, or communities engaged. I have also seen the growing emphasis on rigorous measurement and verification in carbon markets, where environmental claims must be supported by evidence.

Both experiences have taught me something important: what we measure shapes what we prioritize. But what we choose not to measure can be just as revealing.

The Conservation Challenge Was Never Just Ecological

I began my career focused on nature: species, habitats, ecosystems, and the complex threats affecting their survival.

Like many conservationists, I quickly learned that ecological challenges rarely have purely ecological solutions.

Deforestation, habitat degradation, overfishing, and biodiversity loss are often connected to human decisions, economic realities, social norms, governance systems, and the way people interact with natural resources.

At one point in my career, I began working with an approach grounded in a simple but powerful idea: many conservation challenges are rooted in human behavior. If we want to change conservation outcomes, we need to understand what drives people's decisions and what can motivate and enable them to act differently.

That realization changed how I approached conservation.

I immersed myself in theories of social and behavioral change, learning how attitudes, social norms, incentives, perceived barriers, and collective action influence decisions. More importantly, I learned to translate those concepts into conservation strategies.

It became clear that raising awareness was not the same as changing behavior. And changing behavior was not necessarily the same as achieving conservation impact.

There was a chain of change we needed to understand, test, and monitor.

That lesson has remained central to my work ever since.

The Problem with Counting What Is Easy to Count

Conservation and development projects have long relied on indicators that demonstrate implementation: people participating, workshops conducted, agreements signed, hectares under management, or organizations supported.

These numbers are useful, but they can also create an illusion of success.

Imagine a conservation project that trains 500 farmers in sustainable practices. The project reaches its target, reports successful implementation, and closes with positive results.

But what happened afterward?

Did farmers adopt different practices? Were those practices economically viable? Did they reduce pressure on surrounding forests? Did biodiversity benefit? And were the changes sustained?

The difference between delivering an activity and achieving impact can be enormous.

Of course, the conservation sector has developed sophisticated approaches to ecological monitoring and impact evaluation. But in practice, funding cycles, donor reporting requirements, limited resources, and implementation pressures can lead us to prioritize what is easiest to demonstrate.

Sometimes we become very good at measuring how much we do without sufficiently understanding what changes because of it.

We need to move from measuring the delivery of conservation to measuring the changes that conservation interventions are intended to create.

What Carbon Markets Have Made Me Question

Entering the private sector, particularly nature-based carbon markets, introduced me to another level of scrutiny around environmental impact.

In high-integrity carbon projects, emission reductions or removals must be quantified and monitored using defined methodologies, with independent verification of climate claims. Baselines, additionality, leakage, permanence, and uncertainty are not optional details. They are essential to understanding whether the climate benefits being claimed are credible.

This discipline has made me reflect on how we approach the social dimension of conservation.

We recognize that communities, their decisions, livelihoods, rights, and relationships with natural resources are fundamental to long-term conservation outcomes. We invest in engagement processes, livelihood initiatives, capacity building, governance, and benefit-sharing arrangements.

But are we measuring whether these strategies actually work with the same seriousness that we apply to climate outcomes?

Are we evaluating the quality of participation, changes in behaviors, the effectiveness of community governance, livelihood improvements, or the distribution of benefits?

And are we using that information to improve our projects?

Carbon can be quantified in tons. Social change cannot be reduced to a single metric. But that does not make it any less important or any less measurable.

It simply requires different approaches, combining quantitative evidence, qualitative analysis, and the perspectives of the people involved.

How We Work Matters as Much as What We Achieve

One of the strongest convictions I have developed throughout my career is that the way conservation projects engage with communities is not simply a means to achieve environmental targets.

It matters in its own right.

Free, Prior and Informed Consent (FPIC), respect for human rights, meaningful participation, equitable benefit sharing, and accessible grievance mechanisms are fundamental to responsible conservation.

They cannot be reduced to checklists, signed documents, or the number of consultation meetings conducted.

A community may attend multiple meetings without having a meaningful voice in decisions. An agreement may be formally documented without everyone fully understanding its implications. A benefit-sharing mechanism may exist without being perceived as fair or transparent by the people it is intended to serve.

These are not minor implementation details. They can determine whether a project builds trust, respects rights, and creates the conditions for long-term collaboration.

And they deserve to be monitored.

Are people adequately informed? Do they feel their voices influence decisions? Are commitments being fulfilled? Are grievances addressed effectively? Are women and marginalized groups able to participate meaningfully? Are benefits reaching those they are intended to reach?

Importantly, respect for rights is not conditional on whether it improves conservation performance. It is a responsibility in itself.

A project cannot claim success solely on the basis of environmental outcomes if the processes used to achieve them undermine people's rights or well-being.

The Real Power of Monitoring Is What We Do with the Evidence

Perhaps the most important lesson from working across different conservation approaches is that monitoring should never be an end in itself.

Too often, monitoring is treated as a reporting function: collect the data, update the indicators, prepare the report, and move on.

But conservation takes place in complex and constantly changing social and ecological systems. Our assumptions are not always correct. Interventions do not always work as expected. Communities' circumstances change. New risks emerge.

This is why adaptive management is so essential.

A community strategy should not be a fixed set of activities established at the beginning of a project and implemented regardless of what happens on the ground.

It should be a living strategy, informed by evidence and continuously adjusted.

If a livelihood initiative is not reducing pressure on forests, we need to understand why. If participation is increasing but trust is declining, we need to reconsider our approach. If a behavior change intervention is not leading to the expected adoption of sustainable practices, we need to revisit our assumptions.

And if communities tell us something is not working, that feedback should influence what happens next.

This is where my early experience applying behavioral and social change theories connects with my more recent experience in carbon markets.

A theory of change is not just a diagram in a project proposal. It is a set of hypotheses about how and why change should happen.

Monitoring allows us to test those hypotheses.

Adaptive management allows us to act on what we learn.

The purpose of measuring impact is not simply to prove that we were right. It is to discover where we need to do better.

Two Worlds, One Opportunity

After more than two decades in NGOs and four years in the private sector, I have come to appreciate what each can contribute.

The conservation NGO sector brings deep ecological knowledge, experience in participatory approaches, understanding of social and behavioral change, and decades of working with communities and complex conservation challenges.

High-integrity carbon markets bring a strong emphasis on measurable climate outcomes, long-term monitoring, verification, and accountability.

Neither approach has all the answers.

The NGO sector can benefit from continuing to strengthen its focus on measurable, lasting outcomes rather than primarily reporting activities and outputs. Carbon project developers, meanwhile, need to apply greater rigor to understanding social outcomes, rights, community relationships, and the effectiveness of their engagement strategies.

The opportunity is not to copy one sector's approach into the other. It is to bring together ecological science, social and behavioral insights, rights-based approaches, rigorous monitoring, and adaptive management.

It is also to recognize that conservation outcomes and social outcomes are interconnected without assuming that one can substitute for the other.

A forest can be standing while community concerns remain unresolved. A community program can be well received without reducing threats to biodiversity. Both dimensions need attention, evidence, and accountability.

The Question I Keep Coming Back To

Looking back on my journey, I realize that my understanding of conservation impact has continued to evolve.

I started by focusing on what needed to be conserved. I learned to ask what human behaviors and decisions needed to change. And more recently, I have become increasingly focused on how we measure those changes, understand their consequences, and use that knowledge to guide implementation.

Today, I believe we need to ask ourselves more demanding questions.

Not just how many people participated, but whether their participation was meaningful.

Not just how many activities we implemented, but what changed as a result.

Not just whether we delivered on our plans, but whether those plans are still the right ones.

Not just whether we can demonstrate environmental impact, but whether we are achieving it while respecting rights and contributing to positive social outcomes.

And, above all, whether we are willing to change course when the evidence tells us we should.

Because the real measure of conservation success is not how much we do, or even how much we measure. It is what changes for nature and people, how those changes are achieved, and whether they last.

After 25 + years, I am still learning. And perhaps that is the most important lesson of all: effective conservation requires not only the commitment to act, but also the humility to question, measure, listen, and adapt.
