GHz Last Mile Research Latam + BRISE

The Environmental Layer

A new dimension for qualitative research in climate communication.

Preliminary conversation
June 6, 2026

Why we're writing

Over the past five years, GHz has been Nimbly's partner for qualitative research in Brazil and Latin America. We've delivered qualitative studies, digital immersions, and cultural insights across multiple projects for Nimbly's clients, including PEC.

Recently, we've developed a new capability that we believe can change what qualitative research can do in the climate space.

The gap we see

Qualitative research captures what people feel. Environmental data captures how the world works. No one connects the two.

When a participant in Brasilia says "I worry about water shortages," we record it as sentiment. We don't know whether the aquifer beneath their city dropped 3 meters last month or held steady. We don't know if air quality in their neighborhood has been declining for six weeks. We don't know if the heatwave they mention is statistically anomalous or within seasonal norms.

That gap between lived experience and environmental reality is where some powerful insights hide.

What changed

GHz has partnered with BRISE, a Brazilian environmental intelligence startup that builds and operates microlocal sensor networks, integrates satellite imagery and public APIs, and delivers continuous environmental monitoring with prescriptive intelligence.

This isn't a data vendor. It's a research infrastructure partner with field-deployed hardware, proprietary data pipelines, and the analytical capacity to translate raw environmental signals into research-ready context.

Groundwater monitoring

Continuous aquifer-level tracking in Serra do Japi (São Paulo State), one of the last preserved Atlantic Forest regions. A single industrial operation consumes 56.6% of a protected area's water without knowing if the aquifer can sustain it.

Dengue outbreak prediction

ML models crossing 10 years of climate and epidemiological data. 73.5% accuracy using only public weather stations. Key finding: climate conditions 4 to 8 weeks prior predict outbreaks.

Amazon deforestation detection

CNNs applied to Sentinel-2 and Landsat satellite imagery. Finalist at the Tech4Positive Futures global ESG award. The project that gave birth to BRISE.

Indoor air quality

Continuous IAQ monitoring in corporate environments, tracking pollutants like formaldehyde from composite wood furniture.

Municipal Climate Atlas

95 public climate tools mapped across Brazil. 1,594 municipalities in critical condition. Diagnosis is strong; prescription is nearly nonexistent.

Immediate value

Two things we could do in the short term

Path 1

Living Context

The environmental layer as a qualitative research instrument.

Imagine the current Nimbly ethnographic study for PEC — a 3-day digital immersion exploring climate narratives across the languages of territories of Health, Love, Justice, and Energy Freedom.

Now add this: during the study, BRISE sensors are running in the participants' regions, capturing air quality indices, temperature anomalies, groundwater levels, soil moisture, and precipitation patterns.

Nothing changes for the participant. They answer the same questions, share the same stories. But on the analysis side, many things shift.

Illustrative findings

"Participants in regions where air quality deteriorated over the previous 4 weeks showed 2.3x stronger emotional response to 'Health' messages, even when they didn't consciously mention air quality."
"The Justice narrative resonated most in communities where temperature anomalies exceeded +2°C relative to the 10-year local average, suggesting lived thermal stress amplifies perceived unfairness."
"Participants in water-stressed regions spontaneously used language aligned with 'Love' ('losing what we have') at 3x the rate of participants in water-stable regions."

These are illustrative, not empirical. They show the kind of insight that becomes possible when you overlay environmental data on ethnographic research. No other qualitative research partner in the world can do this today.

Environmental variables available

  • Groundwater level
  • PM2.5 / PM10
  • CO₂
  • VOCs
  • Formaldehyde
  • Temperature
  • Humidity
  • Soil moisture
  • Precipitation
  • UV index
  • Noise levels

What if, instead of asking participants to imagine the future, we gave them possible scenarios to react to?

Path 2

The Time Mirror

Environmental projections as qualitative research stimuli.

In PEC's narrative testing studies, participants imagine a beloved place 10 years from now. Today, they imagine in a vacuum. BRISE generates local environmental projections based on actual time-series data: not global climate models, but site-specific trends from primary sensor readings.

Beyond water: projection examples across domains

Air quality, São Paulo

"Average PM2.5 exposure in your neighborhood has increased 18% over the past 3 years. At this rate, by 2036…"

Heat islands, Belo Horizonte

"Your district recorded 47 days above 35°C last year, up from 28 days a decade ago. The projection for 2036…"

Coastal erosion, Pernambuco

"Satellite imagery shows the state's south shore beaches have lost X meters of shoreline since 2016. The trend suggests…"

Urban flooding, Porto Alegre

"Your watershed has experienced Y extreme precipitation events in the last 5 years, compared to Z in the previous decade."

Each projection is local, verifiable, and built on primary data. Each triggers a qualitatively different emotional response than a generic "imagine climate change."

Extended horizon

Where this can take us

The two paths above strengthen what Nimbly already delivers to PEC. The four below explore where the environmental layer could go as the partnership with GHz + BRISE evolves.

Path 3

Environmental Triggers

Sensor data as campaign timing intelligence. BRISE detects precursor signals (declining aquifer levels, dropping soil moisture, rising urban heat island intensity, worsening air quality) days or weeks before events reach public awareness. A "dual trigger" system extending PEC's campaign activation window with geographically precise delivery.

  • Soil moisture as drought precursor
  • PM2.5 as respiratory health trigger
  • Urban temperature anomalies
  • UV index patterns

Path 4

The Invisible Crisis

Local environmental evidence as narrative infrastructure for new markets. PEC's "Later is Too Late" covers 70% of the world's population, but campaigns stay in the US. Brazil is a critical, under-explored frontier. GHz + BRISE provide local sensor-backed evidence, anchoring PEC's first locally-calibrated campaign on local proof, not global abstraction.

  • Aquifer depletion
  • PM2.5 trends
  • Urban heat islands
  • Deforestation rates
  • Disease vector conditions

Path 5

Clean Energy, Safe Water

Bridging energy policy and local environmental impact. GHz + BRISE make the causal chain observable at local scale: rising temperatures leading to reduced aquifer recharge, worsening air quality leading to healthcare costs, extreme heat driving energy demand spikes. Each link documented with primary data, connecting "clean energy transition" to "protecting your water supply" and "your children breathing cleaner air."

Path 6

The Narrative Thermometer

Environmental data as a control variable for message effectiveness monitoring. Was the message effective because it was well-crafted, or because the audience's environmental context made them more receptive? In sensor-instrumented regions, it's possible to correlate message effectiveness with actual environmental conditions during the study period. The kind of finding that generates peer-reviewed publications and strengthens PEC's scientific foundation.

What we're not proposing

This is not a pitch.

We're presenting a capability that GHz has developed by investing in BRISE: a dimension in qualitative research that doesn't exist anywhere else in the research market.

We'd like to explore, together, which of these paths — or others we could imagine together — might create value for Nimbly's clients and research practice.

The next step is a conversation.
