I was going to suggest SOFIA as well as the most recent. Haven't seen other data, it seems that growth is pretty much topping off, so the 2014 data aren't probably that far from reality. Number of farms is growing quickly in Europe, but still negligible on world scale.
There is always a 2 years lag in statistics so that they are accumulated (and validated) at the national level and then the international level. The most updated data are for 2014 with the FAO/SOPHIA.
The most authentic data you would get in FAO 2016 report for 2014 production which was estimated at about 27 million tons wet weight (value USD 6 or 7 billion). As other experts commented, you will get only after two years only not sooner.
