An updated TFP series for South African Agriculture with improvements to official data on land, labour, and machinery measurements
The agricultural sector in South Africa has undergone significant shifts over the years, raising substantial concerns about food security and productivity. This comprehensive study analyses these trends and their implications to offer insights for policy formulation to address these challenges. The …
