Locating people living in poverty, such as through door-to-door surveys, sometimes is difficult. Therefore, scientists are now turning to satellite images.
Childhood Poverty, Parental Abuse Linked to New Health Problems Years Later
Growing up in poverty or being abused by parents can lead to accumulated health problems later in life, suggested a new research.

‘Scientists are now turning to satellite images to locate people living in poverty.’
"Our method, which requires only publicly available data, could transform efforts to track and target poverty in developing countries," the researchers said in their paper. According to World Bank data from 2000 to 2010, 39 out of 59 African countries conducted less than two surveys, from which nationally representative poverty measures could be constructed.
Overall, surveys are costly, infrequent, and cannot always reach countries or regions within countries, for instance, due to armed conflict.
Center and States Must Move Together to End Poverty in India: Narendra Modi
The political deadlock over Land Acquisition bill is seriously impacting rural development, including the creation of schools, hospitals, roads, irrigation projects.

However, nightlight data alone is not effective at differentiating between regions at the bottom end of the income distribution, where satellite images appear uniformly dark.

Silk Production Has Hiked in India, Offers Farmers A Way Out of Poverty
In a delicate procedure, the tribal community extracts the silk thread from cocoons spun by the worms by boiling them to make them softer and collection easier.

The researchers then developed a sophisticated learning algorithm that categorizes these features and found that this method did a surprisingly good job predicting the distribution of poverty.

"We demonstrate an accurate, inexpensive, and scalable method for estimating consumption expenditure and asset wealth from high-resolution satellite imagery," the study said.
"It also demonstrates how powerful machine learning techniques can be applied in a setting with limited training data, suggesting broad potential application across many scientific domains."
