Followed by new crops and techniques, increases in output and land improvement, but also urban growth, agriculture became much more productive. Institutions such as enclosures and large farms are said to have increased productivity by encouraging farmers to adopt those new crops and techniques. However, there is little direct evidence for the actual impact of changes in land tenure on agricultural productivity. Indeed, the consequences of the enclosure movement on agricultural productivity has been a deeply debated topic in English economic history. The Bing-Bang was a trigger for the agricultural revolution. Indeed, the Black Death of 1348 was one of the greatest pandemics in human history. It killed 75 to 200 million people in mid-14th century. Population in England and the Low Countries recovered slowly from the plague.
