Landscape Assessment & BECOME Project

The Brief

The Magaliesberg Biosphere, in collaboration with the University of Pretoria, needed to conduct a wide-reaching landscape assessment to inform their ten-year review and support the global BECOME project — a seven-university consortium investigating youth engagement and conservation in biospheres worldwide.

The objectives were twofold: capture perceptions, challenges, and benefits of living in the biosphere from diverse community voices, and increase youth participation in research — supplementing previous in-person youth workshops with a digital, scalable data collection method.

They also wanted to pilot an accessible, media-rich, mobile-first methodology that could serve as a blueprint for future NGO and impact projects across Africa and beyond.

The Challenge

Conservation research in biosphere reserves has traditionally relied on in-person workshops, paper surveys, and email-based outreach — methods that struggle to reach the communities most affected by conservation policy.

Limited Reach

Traditional paper or email-based surveys couldn't access rural, peri-urban, and youth communities at the scale needed for a representative landscape assessment.

Youth Under-Representation

Previous in-person workshops had engaged some young people, but digital-native youth needed a channel they already used daily — not another platform to sign up for.

Shallow Data

Tick-box surveys captured broad trends but missed the stories — the lived experiences, local knowledge, and emotional connections that drive conservation outcomes.

No Contact Lists

The biosphere team didn't have thousands of individual phone numbers — they needed a distribution method that worked through existing community networks, not one-to-one outreach.

The core question: How do you reach 500+ people across a dispersed biosphere — including youth, rural communities, and local stakeholders — and capture not just opinions but authentic stories, voice notes, and images, without a contact database or an app to install?

The Approach

Yazi provided a WhatsApp-based survey platform that let the biosphere team distribute a single secure link through existing community networks — WhatsApp groups, university lecturers, and Facebook — rather than collecting individual phone numbers.

Survey Design & Distribution

The survey was co-designed by the biosphere team and the University of Pretoria, with ethical clearance handled for the youth component. A secure link was shared with explanatory text and the Biosphere's logo to enhance trust.

How it worked: Instead of collecting individual numbers, the team generated a secure survey link, branded it with the Biosphere's logo and explanatory messaging, and shared it through WhatsApp groups (some with 200+ members), university lecturers, and Facebook. Respondents could reply in their language of choice, use emojis, and submit voice notes, photos, and even short videos.

The participant experience

Community members didn't need to download an app or create an account. They tapped a link in a trusted WhatsApp group and started sharing — in their own language, in their own voice, from wherever they were.

What made this different

Trusted & Familiar

  • WhatsApp is already the primary communication tool for local communities — no new app, no sign-up
  • Branded messaging with the Biosphere's logo built instant credibility and trust
  • Respondents could reply in their language of choice, using emojis, text, or voice

Media-Rich Responses

  • Voice notes — often hundreds of words long — delivered story-driven insights about daily life, conservation challenges, and local sentiment
  • Photos ranged from local landmarks to daily scenes, adding qualitative depth beyond tick-boxes
  • Video submissions captured context that text alone could never convey

Network Distribution

  • A single secure link distributed through WhatsApp groups with 200+ members each
  • University lecturers shared it with students for targeted youth outreach
  • No individual phone numbers needed — the network did the recruitment

Real-Time Monitoring

  • The dashboard showed at which question respondents disengaged, enabling messaging adjustments
  • Drop-off was tracked live and outreach strategies adapted accordingly
  • Under-represented groups were identified early and targeted with follow-up distribution

Results

Reach That Traditional Methods Could Not Achieve

Over 568 people started the survey in the first month — a scale that would have been impossible via phone calls, email, or paper surveys, especially given the dispersed geography and limited existing contact lists.

568+ STARTED THE SURVEY 100% 100+ VOICE NOTES SUBMITTED Rich Mixed DEMOGRAPHICS REACHED Broad

Rich Qualitative Insights

More than 100 voice notes and dozens of images and videos were submitted, providing context-specific evidence that written surveys alone rarely deliver. Audio and visual content allowed the research team to "hear and see" impact stories directly — supporting more nuanced reporting to funders, stakeholders, and the global BECOME consortium.

Community Voice, Captured

  • Voice notes delivered rich, story-driven insights about daily life, conservation challenges, and local sentiment
  • Photos of local landmarks and daily scenes added depth that surveys alone miss
  • Responses could be grouped by area based on self-reporting, offering geographic insight without breaching privacy

Youth & Demographic Reach

  • Effectively engaged youth through university channels and WhatsApp — a digital-native approach
  • Reached a demographically mixed sample spanning youth, adults, rural and peri-urban communities
  • Dashboard filtering by age group showed how different demographics engaged

Inside the Yazi platform

The Magaliesberg team used Yazi's dashboard to filter responses by age group, location, and response type — seeing, for example, how youth versus older adults engaged, and where the richest qualitative data was coming from.

Landscape Assessment
What do you value most about living in or near the Magaliesberg Biosphere?
Response
The mountains and the bush — it's peaceful here. My children know the birds and the trees by name.
Follow-up
That's lovely. What about challenges — what is the biggest issue facing your community in this area?
Response
Please listen to my voice note.
Voice transcript
The biggest problem is development — people are building without thinking about the land. We see more fences going up, more trees coming down. The water in the streams is not what it used to be. I worry that my grandchildren won't see the same Magaliesberg I grew up with.

Learning for Future Research

The Magaliesberg study surfaced important methodological insights for future NGO and impact research projects using WhatsApp.

Survey Design

  • Early placement of complex, reflective questions led to increased drop-off — future surveys should ease in with simpler questions first
  • A mix of checkboxes and open-ended questions kept respondents engaged across different literacy levels
  • The survey period was extended to allow for ethics approval and targeted youth outreach

Distribution Strategy

  • Sharing via trusted WhatsApp group admins with branded communications significantly boosted uptake
  • University lecturer channels proved the most effective route for youth recruitment
  • Facebook served as a useful secondary channel but WhatsApp groups drove the volume

Impact

For the Magaliesberg Biosphere

The biosphere team gathered a large, demographically mixed evidence base for their ten-year review — with qualitative depth that previous methods hadn't delivered. The ability to filter by area and see media responses helped them understand who they were reaching and what was really happening on the ground.

For the BECOME Project

The study provided a scalable, mobile-first methodology that the seven-university BECOME consortium can adapt for youth engagement and conservation research in biospheres across different countries — a replicable blueprint for community-level data collection.

It's a useful tool — you can get quite far and wide, and that's quite nice. The ability to analyse by area and see media responses helps us understand who we're reaching, and what's really happening on the ground. We'd be happy to use it again, and to recommend it to others looking for real community insight.

Why This Matters for Impact Research

Conservation and impact research has long faced a tension between depth and reach. Gathering authentic community voices — the stories, the emotions, the lived experiences that shape policy — has traditionally required in-person fieldwork that limits scale. Meanwhile, digital surveys scale but lose the richness.

The Magaliesberg study showed that WhatsApp can bridge that gap. By meeting communities on the platform they already trust, with the ability to respond in their own voice and their own language, the biosphere team captured something that neither a paper survey nor a focus group could: 568 people, dozens of voice notes and images, geographic insight, and a dataset rich enough to inform a global university consortium — all from a single secure link shared through existing community networks.
