That’s why we need people who can bridge the gap—helping teams understand the potential, select the right datasets aligned with real project needs, and combining them with ground realities to generate practical insights.

But as the volume of data increases and the landscape expands, it may become harder for non-technical users to navigate and fully benefit from earth observation.

Second, the satellite data ecosystem will continue to grow—driven by ongoing research advancements, new satellite missions, and faster processing technologies. That’s good news.

In later stages, satellite data—when combined with knowledge from the field—can lead to more practical and robust insights than would be possible without it.

Even years later, the key lessons still apply:
First, satellite imagery should be seen as an input to your work. In the early stages, it helps you leverage its key advantages to generate initial observations, raise meaningful questions, and guide fieldwork.

A few years ago, I used satellite imagery for the first time in an impact evaluation with ADE in Rwanda—when COVID made fieldwork impossible. Applying satellite data in a real-life case helped me understand both its advantages and limitations —lessons I now share in this blog article.

Not Just Theory: Lessons from Using Satellite Imagery in Real-Life Impact Evaluation Discover how satellite imagery can fill data gaps, support impact evaluation, and generate actionable insights when combined with field knowledge.

🛰️ Satellite imagery won’t replace fieldwork — but it can take you much further than you think.

An image of Esther Duflo and the quote: "The key to fighting poverty is not grand gestures, but small, tested interventions that actually work." - Esther Duflo And more: French economist Esther Duflo has transformed the study of poverty and economic development, applying rigorous field experiments and geospatial analysis to assess real-world impacts. She has used GIS data to study how infrastructure projects—like dams and transportation networks—affect economic growth and poverty, ensuring that policies are backed by evidence rather than assumptions. In 2019, she became the youngest person and only the second woman to receive the Nobel Prize in Economics, alongside Abhijit Banerjee and Michael Kremer. Her groundbreaking work combines economics, field research, and GIS mapping to create effective solutions for global poverty. Through her research, policymakers gain real insights into how geography shapes economic opportunity.

#WomensHistoryMonth Day 16: Esther Duflo revolutionized the fight against poverty by applying data-driven research and GIS analysis. A Nobel Laureate in Economics, she maps the impact of infrastructure & policies on communities, ensuring interventions truly work. #Shero #GISChat

Sentinel-2A: Extended Campaign Starting March 13, 2025 Copernicus Data Space Ecosystem - Europe's eyes on Earth

⏰𝗥𝗲𝗺𝗶𝗻𝗱𝗲𝗿⏰
The #Sentinel-2A extension campaign begins in 𝘁𝘄𝗼 days, improving the global revisit frequency of the Sentinel-2 constellation. Particularly beneficial for observing tropical regions in Africa and South America with high #cloud cover.

Anthropogenic climate change doubled the frequency of compound drought and heatwaves in low-income regions - Communications Earth & Environment From 1981 to 2020, low-income regions experienced a faster increase in the frequency of compound drought-heatwaves events than high-income regions, and the increase is attributed to anthropogenic clim...

Queridos periodistas,
No se debe usar "desastre/catástrofe natural". Los desastres provocados por riesgos naturales son siempre el resultado de las acciones y las decisiones humanas. Un desastre no es natural y que las acciones humanas pueden prevenir y mitigar sus impactos. Aquí otros conceptos:
