A mapping exercise to gauge land use in central India, with technology and traditional knowledge, aims to improve rural livelihoods by restoring forests and grasslands, and stem the flow of migration to the country's overcrowded cities.
The week-long Mapathon, conducted by research group World Resources Institute (WRI), is using data collection tool Collect Earth, and very high-resolution satellite images to study land use in Sidhi district in the central state of Madhya Pradesh.
Data collected by 10 young professionals, and 10 locals of an area of around 3,80,000 hectares (1,470 sq miles), will be a pilot to study land degradation, and how to restore the land to sustainable use, said Rohini Chaturvedi at WRI.
Rohini ChaturvediTypically, when we use high-res images, we leave out the people who are engaging with the land on a daily basis. Rohini And people in rural areas know their immediate surroundings really well ....so this exercise will break that divide.
Importance of Using Satellite Images Used in Rural Areas
Satellite images are being increasingly used in rural areas to map landholdings in the absence of updated records.
India has pledged to keep a third of its total land area under forest and tree cover.
But an expanding population and increasing demand for land for industrial projects has placed greater stress on these areas, displacing rural communities, hurting livelihoods and increasing their vulnerability to climate change.
How the Satellite Images Can Restore Land
Every year, tens of thousands of villagers migrate to India's cities in search of jobs as drought and diminishing land holdings drive down farm incomes.
Although India's forest cover has increased in recent years due to stricter laws and conservation efforts, more than 2,500 sq km (965 sq miles) of forests have been wiped out since 2013, according to official data.
More than 100 million hectares (386,000 sq miles) of land in the country can be restored, WRI estimates.
That will benefit the more than 60 percent of the population that depends directly on the land for food, fuel and fodder, Chaturvedi said.
"Landscape restoration in Sidhi and elsewhere can improve livelihood opportunities through improved productivity and food security, water availability, as well as biodiversity conservation," she said.
