Locusts are seen on a tree on the outskirts of Sukkur, southern Pakistan, on July 1, 2020. According to the country's Ministry of National Food Security and Research, the country's annual wheat requirement is 27.47 million tons, but the crop production this year was less than 25 million tons due to multiple factors including locust attacks, untimely heavy rains and infestation of fungal disease yellow rust.
