year between 2009 and 2012. In November 2010, the International Monetary Fund described the Zimbabwean economy as "completing its second year of buoyant economic growth". The pan-African investment bank IMARA released a favourable report in February 2011 on investment prospects in Zimbabwe, citing an improved revenue base and higher tax receipts. In January 2013, the finance ministry reported that they had only $217 in their treasury and would apply for donations to finance the coming elections. By 2014, Zimbabwe had recovered to levels seen in the 1990s but growth faltered between 2012 and 2016. Inflation was 42% in 2018; in June 2019, the inflation rate reached 175%, leading to mass unrest across the country. Minerals The mining sector is lucrative, with some of the world's largest platinum reserves being mined by Anglo American plc, Zimplats, and Impala Platinum. Zimplats, the nation's largest platinum company, has proceeded with US$500 million in expansions, and is also continuing a separate US$2 billion project, despite threats by Mugabe to nationalise the company. The Marange diamond fields, discovered in 2006, are considered the biggest diamond find in over a century. They have the potential to improve the fiscal situation of the country considerably, but almost all revenues from the field have disappeared into the pockets of army officers and ZANU–PF politicians. In terms of carats produced, the Marange field is one of the largest diamond-producing projects in the world, estimated to have produced 12 million carats in 2014 worth over $350 million. , Metallon Corporation was Zimbabwe's largest gold miner. Agriculture Zimbabwe's commercial farming sector was traditionally a source of exports and foreign exchange and provided 400,000 jobs. However, the government's land reform program badly damaged the sector, turning Zimbabwe into a net importer of food products. For example, between 2000 and 2016, annual wheat production fell from 250,000 tons to 60,000 tons, maize was reduced from two million tons to 500,000 tons and cattle slaughtered for beef fell from 605,000 head to 244,000 head. Coffee production, once a prized export commodity, came to a virtual halt after seizure or expropriation of white-owned coffee farms in 2000 and has never recovered. For the past ten years, the International Crops Research Institute for the Semi-Arid Tropics has been assisting Zimbabwe's farmers to adopt conservation agriculture techniques, a sustainable method of farming that can help increase yields. By applying the three principles of minimum soil disturbance, legume-based
