affordable satellite imagingSatellite imaging is an amazing technology that allows humans on Earth to see pictures of space without having to leave the surface of the planet. More than that, satellite data can give vital information that will help solve problems and make changes to better society and the planet. Since this technology is expensive, organizations are trying to prioritize affordable satellite imaging.

Affordable Satellite Imaging

Satellite imaging is more complicated than it appears. Satellites are extremely expensive to create and put into use because they need to survive in space. As of April 2021, more than 6,000 satellites are orbiting Earth. About 3,000 of those are inactive, and more than 700 are imaging satellites. However, only the most wealthy and educated experts have access to the images that these satellites create and can interpret them correctly.

With an expansion of access to the information that satellite imaging collects, there could be more solutions for problems in society, including poverty. A group of researchers at the University of California, Berkeley may have made that possibility a reality.

The Creation of MOSAIKS

On July 20, 2021, Nature Communications published a study by the researchers stating that “combining satellite imagery with machine learning (SIML) has the potential to address global challenges by remotely estimating socioeconomic and environmental conditions in data-poor regions.” However, SIML has limited accessibility and use because of the resources it requires. The Berkeley team aims to lower the computational cost with a new system that rivals competitors. 

The team creating the machinery consists of the Global Policy Lab directed by Solomon Hsiang and Benjamin Recht’s research team in UC Berkeley’s Department of Electrical Engineering and Computer Sciences.

After a great deal of hard work, the team created a system called Multi-Task Observation using Satellite Imagery & Kitchen Sinks (MOSAIKS). The system has the power to analyze hundreds of data variables that satellite imaging picks up while making it affordable and easy to use.

Co-author and Ph.D. student Esther Rolf said that “We designed our [satellite images] system for accessibility so that one person should be able to run it on a laptop, without specialized training, to address their local problems.”

How MOSAIKS Affects Global Poverty

If developing countries implement MOSAIKS, it could help decide something like where is best to build a road. This knowledge would help under-served communities that currently have low access to infrastructure.  

MOSAIKS can find the best freshwater source, farmlands, highest human populations and more. MOSAIKS does all of this at a low cost and in a user-friendly way. For developing countries, affordable satellite imaging could be the key to growing further out of poverty.

Both Rolf and Hsiang are hopeful for the further development of MOSAIKS and what it can do for the future. With affordable satellite imaging technology on the horizon, the eradication of global poverty could become more of a reality.

Space Technology Combats PovertySpace technology is a multifaceted tool that can help preserve the environment and improve agricultural success. Space technology combats poverty in communities by tracking global poverty, monitoring natural disasters, measuring pollution, protecting wildlife and managing resources.

Tracking and Predicting Poverty

Space technology is an emerging method for pinpointing and combating poverty. Data from satellites and algorithms can help countries accurately determine the most impoverished communities in need of resources in order to best assist the communities.

For example, nighttime images from satellites can reveal the areas that can afford electricity and the areas that cannot. Nighttime electricity use can have greater implications for economic activity and performance, which governments can study to better understand the distribution of wealth.

Once governments understand the geography of poverty in their countries, governments can distribute resources effectively. Satellites can also capture images of crops to help farmers estimate their harvest sizes. At large, countries can use crop data to understand local economies, assist farmers with crop insurance and warn them about potential crop failure.

Monitoring Natural Disasters

Space technology also combats poverty by monitoring natural disasters around the world. Satellites track a wide range of natural disasters, including wildfires, earthquakes, tsunamis, storms and floods. Satellites can also locate human-prompted events such as industrial accidents and oil spills.

By tracking global environmental disasters, space agencies allow the international community to pinpoint at-risk areas and distribute aid accordingly. Countries can use satellite data to better prepare for environmental disasters and identify the regions that will experience the most damage, and therefore, require the most aid. Additionally, when satellites predict an impoverished community will experience a natural disaster, the community can more effectively prepare for it in order to mitigate damage and destruction.

Protecting the Environment

Satellites can also be used to measure pollution and protect wildlife. By measuring water, air and soil pollution, satellites can distinguish between natural resources that are safe to consume and natural resources that are best used for agricultural purposes. Satellites can also locate areas contaminated by oil spills and mining activities.

With this knowledge, governments can work more efficiently to contain and address pollution. Additionally, satellites protect wildlife by tracking changes in ecosystems. The use of satellites helps the global community understand and preserve biodiversity by monitoring various habitats and species.

Countries can use information from satellites to make more constructive efforts at maintaining wildlife, natural resources, and ultimately, agricultural success. Space technology combats poverty by protecting the environment and improving agriculture in impoverished areas.

Managing Resources

Space technology can also locate and manage natural resources in impoverished areas. According to the United Nations Office for Outer Space Affairs, space-based innovations are promising solutions to environmental and natural resource-related conflicts in developing countries. Remotely collected data from satellites can inform areas of study such as agriculture, geology, surveying, inventory and land use.

Experts in these fields can use knowledge from satellite data to help impoverished communities maximize land use and natural resources. As a tool for collecting expansive global data, space technology combats poverty by helping developing countries gather and monitor data to make the most informed decisions.

With the help of satellites, governments can locate vulnerable areas and direct aid to the people most in need. Space technology ensures decision-making targets those who will benefit the most.

Satellites and Food Security
Nearly 800 million people in the world do not have enough food to eat. It is no secret that more efficient farming and agricultural practices can help yield more crops to feed more people as well as bring in more income to poor farmers. In conjunction with traditional ground-based data collection of farmland, satellite imaging and sensing can help farmers monitor their crops and land condition in real time. Satellite-based technology can map cropland area and crop type, estimate area planted, estimate product yield and even detect early signs of droughts and floods. With this kind of technology, farmers may be better equipped to make informed choices about their land to protect their products. With more informed farmers, better use of resources and ultimately more crops, satellites may be an important part of ensuring global food security.

A New Wave of Tech

Precision farming is the use of technologies to inform farmers about their products. This method is not new, however, the systems in place are changing. Traditional, ground-based tests, such as soil sampling, have long been used to test the arity, salinity, and other conditions of land. These tests help instruct farmers about the optimal mix of fertilizer, pesticide and water that should be used to yield the most crops. While these tests are useful, they are expensive, time-consuming and can only provide data for a small area of land.

Satellites may provide a comprehensive solution. Equipped with imaging and sensing technology, satellites may analyze entire fields at more regular intervals for a more timely and lower-cost option. With land-use mapping and monitoring technologies, satellites cater to a variety of farmers’ needs. Farmers are using satellite technology to:

  • Analyze soil fertility.
  • Map irrigated land.
  • Monitor crop growth.
  • Produce crop yield forecasts.
  • Track crop development.
  • Measure soil moisture content.
  • Test soil chemical composition.

Depending on the program and type of imaging, the costs of satellite data may differ. The Sentinel-2, a land-monitoring system of two satellites that the European Space Agency (ESA) controls, provides vegetation imagery and moisture maps to farmers for $0.20 per acre per two months of service.

Satellites: Prediction, Protection and Prevention

In places like sub-Saharan Africa where agriculture accounts for 64 percent of all employment, satellite-based technology is vital to the survival of farmers. Ninety-five percent of sub-Saharan Africa’s farmable land lacks irrigation systems, thus making the farmland more susceptible to drastic land conditions like droughts and floods. With satellite technology and remote sensing, farmers can shift their focus from reacting to disasters after they occur to planning response before the disasters cause damage. Because low soil moisture content is an indicator of drought, satellites can measure the soil’s moisture content using microwave radiation and send an early warning to farmers in the affected area.

With these early response mechanisms, insured farmers can apply early to their insurers and receive money. Programs like the Ethiopian Productive Safety Net Program provides cash-transfers to poor households using this satellite-based technology.

People have used satellite drought imaging combined with data on local market supply and demand to bring the right amount of food aid to countries in need. Molly Brown, a researcher for NASA, uses satellite images of cropland in Niger, where farmers not only grow food for markets but also eat the crops, to estimate rising market costs. During droughts, these farmers cannot grow enough food to feed themselves and sell locally, thus demand and market prices increase. Since many rural families in Niger live on only around $400 a year, drastic price increases may mean that they cannot get enough to eat.

The goal of Brown’s research is to predict rising market prices before they occur based on satellite images of farmland. It is also to bring in enough food aid when people need it and to stop food aid when it is not necessary. Brown hopes satellites will be an important step toward ensuring food security.

Already at Work

Many organizations, large and small, have already begun harnessing the power of satellite technology and its use in agriculture. NASA has rolled out several satellite-driven initiatives to help combat food security. The Famine Early Warning Systems (FEWS) Network, established in 2000, uses NASA’s Landsat satellite imaging and remote sensing to gather data, forecast weather trends and hazards and create maps for vegetation, rainfall and water use. In order to make satellite imaging and data more accessible to the communities that could best utilize them, NASA established a web-based visualization and monitoring system, for Africa and Central America, called SERVIR, in collaboration with USAID.

Working with more than 200 institutions and training around 1,800 regional support staffers, SERVIR provides previously inaccessible satellite data, imaging and forecasts to local governments and researchers. With this information, SERVIR hopes that developing nations will be able to respond better to natural disasters, improve their food security and manage water and other natural resources.

Even private companies like Planet Labs, are investing in satellite-based technology. Planet uses many smaller, relatively inexpensive satellites for its imaging force. The company has around 140 currently deployed, enough to capture an image of the entire Earth every day. It sells imaging and monitoring data to over 200 customers, many of whom are agricultural companies.

In 2015, at the U.N. Sustainable Development Summit, Planet Labs introduced its Open Regions initiative. By making $60 million worth of its satellite imagery for certain regions available to the global public and directly accessible online, Planet Lab’s imagery brings data vital to the health of crops directly to farmers. With the U.N. deadline to end global hunger and ensure global food security by 2030, it is important for governments and organizations to look for new, sustainable opportunities to increase productivity. By looking beyond conventional, ground-based agricultural solutions and turning to the skies, farmers may find that satellites may be an important part of ensuring global food security.

Not many people would think of satellite technology as something that is helpful for developing countries, but it is an investment that can help countries achieve more sustainable development. Satellites’ ability to connect and communicate is essential for developing countries, especially in rural areas. These advancements are a boon to the Sustainable Development Goals (SDGs) that were adopted by the United Nations in 2015.

Some specific ways that satellite technology can be used by developing countries are for communication in disaster areas, obtaining information about weather for use in agriculture and fishing and sharing medical information. By improving these areas, satellite technology can be used as one solution for many SDGs. For example, by using information gathered about agriculture and fisheries, satellites are assisting in the development of economies. In some countries, illegal fishing is a problem that satellite technology can help reduce, which improves the livelihoods and security of people in the fishing industry. Communication about healthcare (for general care or in disaster areas) and education improves people’s safety and gives them access to education.

Satellite technology is helping developing countries such as Indonesia and Nigeria. In Indonesia, the U.K. space agency Inmarsat has a program aimed at improving the management of the fishing industry, which is important to the economy in Indonesia. The program uses satellite-based tools on fishing boats in order for the government to collect data that can reduce illegal fishing practices, while also being a tool to relay information about the weather to fishermen that are out at sea.

In Nigeria, Inmarsat has launched another project that is benefiting healthcare systems. Satellite technology is being used in research institutions as well as the federal and state health centers. The research institutions are using satellite technology for data collection to see what needs to be improved. The health centers use satellite technology for communication, disease surveillance and video-based training for their staff.

By helping improve communication and data collection, satellites are a beneficial investment for the sustainable development of countries. The improvements that can be made to their economies as well as their healthcare systems can improve people’s security and save lives.
