Recent estimates show the world population could reach 10 billion people by the year 2050. That leads to the continuous chatter of whether or not we’ll be able to feed a growing population with our current resources.
Food availability starts with enough land to grow crops for human and animal consumption. The good news here is that we have more cropland than we previously believed.
A new map showing cropland worldwide was recently released. It revealed that there are 1.87 billion hectares — or 4.62 billion acres — of cropland on Earth. This estimate is 15 to 20 percent higher than earlier assessments.
This clearer picture comes from a more accurate understanding of areas that were never mapped before or that were mapped incorrectly. The study was led by the USGS (United States Geological Survey) as part of the Global Food Security-Support Analysis Data at 30 m Project. The map was created using mostly Landsat satellite imagery with 30-meter resolution, the highest spatial resolution of any global agricultural dataset.
India tops the list with the most cropland at 179.8 million hectares (444.3 million acres). That is almost one-tenth (9.6 percent) of the world’s net cropland area. Coming in second is the United States, with 167.8 million hectares (414.6 million acres; 8.9 percent of global cropland). China is third, with 165.2 million hectares (408.2 million acres, 8.8 percent of global cropland), and Russia is fourth with 155.8 million hectares (384.9 million acres; 8.3 percent of global cropland).
Cropland makes up more than 80 percent of the total area in countries like Moldova, San Marino, and Hungary. It represents between 70 and 80 percent of the land in Denmark, Ukraine, Ireland, and Bangladesh. For countries like the Netherlands, United Kingdom, Spain, Lithuania, Poland, Gaza Strip, Czech Republic, Italy, and India, cropland covers 60 to 70 percent of the ground.In comparison, cropland represents just 18 percent of all land in both the United States and China.
