The Quest for Fit-for-Purpose Earth Observation and Remote Sensing Data

New data sources and innovative approaches using big data techniques, spatial analysis, predictive modeling, and other technologies are creating a range of new datasets that can help measure and monitor SDG-related targets and indicators. And while data availability is vital to tackling any global agenda, more data does not always guarantee good decision-making. To take meaningful action--whether it be a global crisis, like the COVID-19 pandemic, or the recent earthquake in Haiti--policymakers and other SDG stakeholders must understand what data are fit-for-purpose. Earth observation (EO) and remote sensing products have emerged as an important source of data that present an opportunity to monitor environmental, agricultural, and other SDG-related indicators in fine temporal and spatial resolutions. With the increase of near real-time information, how do users identify the best-suited data source for their application of interest?

Covid-19 and Gridded Population Data: New Models, Data Platforms, and Research Highlights

As we continue to confront the COVID-19 pandemic, one could argue that never before has timely and accurate population data been so critical. Population data is necessary to understand everything from the spread of the virus and who is impacted, to where vulnerable populations are located, and levels of population density for establishing effective social-distancing measures. And gridded population data are playing an important role in helping researchers access this type of information. Gridded population maps distribute data using grid cells, combining census results with additional information, such as geospatial data from satellites, to ensure more frequent and granular estimates, which are vital during a constantly evolving epidemic. In this blog, we explore how gridded population data are being used by researchers to inform the COVID-19 response.

Engaging the Scientific Community in the Use of Gridded Population Data

As the world continues to face the immense challenges posed by Covid-19, nontraditional data sources, including gridded population data, play an important role in tracking the virus’ spread and ensuring that no one is left behind. Gridded population maps distribute data using grid cells, combining census results with additional information, such as geospatial data from satellites, to provide more accurate and timely population estimates. However, as our recent report on gridded population data and joint webinar with the International Science Council revealed, while they offer great promise, many policymakers and researchers are still largely unaware of gridded population data, particularly their nuances and potential applications for sustainable development and Covid-19.

Leveraging Population Data in a Time of Crisis

During the current health crisis, knowing where people are located, what conditions they are facing, and their access to basic services and infrastructure is essential. Helping to answer these key needs, gridded population data have emerged and can play an important role in mapping individuals’ vulnerability and ensuring that no one is left behind. Gridded (or raster) population maps represent the distribution of population in rows and columns of grid cells, typically defined by their latitude-longitude coordinates. Population data is redistributed across these grid cells and combined with satellite imagery and other sources to provide more accurate and timely population estimates. Yet, as TReNDS’ recent report, Leaving No One Off The Map: A Guide To Gridded Population Data For Sustainable Development, demonstrates, many policymakers and other users remain largely unaware of these tools, including their nuances and strengths and weakness for potential application. There is a critical need for more validation work and capacity-building in countries. These issues were highlighted during a recent virtual debate, “How Can We Leverage Population Data In A Time Of Crisis,” hosted by TReNDS in partnership with SciDev.net.

Gridded Population Data Has a Role to Play in Ensuring an Inclusive Response to COVID-19

Like any health issue, the impacts of Covid-19 are strongly gendered. Men are believed to be more susceptible to the virus, while women are more exposed in other ways: to an increased care burden, to heightened incidences of gender-based violence, to limited work opportunities, and to job losses. Understanding these gendered experiences and responding accordingly requires data that is disaggregated. It means going beyond the totals of people accessing facilities or losing their jobs, but disaggregating figures on the balance of men and women facing these challenges, including inequalities and discriminatory effects.

Gridded Population Datasets: Which One Is Fit For Purpose?

Access to timely and reliable data on population is critical to delivering global development programs and humanitarian assistance. It helps governments, donors, and implementing partners understand what services people have access to and the challenges they face both geographically and socially. Gridded population datasets — spatial databases on global populations that can be analyzed within mapping software — enable this to be achieved. But awareness of them is low.

In the Fight Against Covid-19: What Do We Know and to Whom Can We Turn for Answers?

One could argue that during the current global pandemic, data has never played such an important role. It is relied on for life and death decisions that are impacting billions of people around the globe. In particular, the need for accurate and real-time data, which many in the data for sustainable development community have been advocating for years, has come to the forefront of mainstream conversations. Yet in the haze of the countless Covid-19 data dashboards and discussions on data, much of the data being reported (especially in the United States) is incomplete, confusing to the general public, and being miscommunicated by journalists and politicians alike. As the spread of Covid-19 continues to increase at an alarming rate, policymakers and citizens each face numerous limitations.

Big Data in a Time of Crisis: Maximizing its Value – And Avoiding its Risks – In the Fight Against COVID-19

It is estimated that approximately 2 million people around the world have been infected by the coronavirus, and the numbers continue to grow. Yet the data being reported are primarily coming from national governments, which are – for the most part – basing it on who has been tested, which likely reveals only a fraction of the scale of the pandemic. There’s a critical need for real-time reported data from hospitals, health clinics and outreach facilities, based not only on testing, but on symptoms and other key determinants. In addition, we need to know in real-time who lacks access to a health clinic or other basic services, and which clinics don’t have personal protective equipment (PPE), ventilators or beds – as well as where the most vulnerable people live, their age, gender and other crucial demographic information. If there is one thing this pandemic has exposed, it is the acute weakness of the world’s data systems.

Gridded Population Data is Key to Leaving No One off the Map

The 2030 SDG Agenda promises to leave no one behind, but to fulfill this promise we need quality, timely, and accurate population data to account for everyone everywhere. Recent innovations in geospatial technology and remote sensing have paved the way for gridded population datasets to help fill these important gaps, but information is still lacking on their unique characteristics, potential, and limitations. These issues were highlighted during this week’s webinar, “Leaving No One off the Map: Gridded Population Data for Decision-Making,” hosted by TReNDS in partnership with Geospatial World Media featuring TReNDS Co-Chair and Director of CIESIN, Bob Chen, and TReNDS Manager, Maryam Rabiee.
