In 2023, the garlic yield in Tanzania was recorded at 24.43 thousand hectograms per hectare. Over the past decade, the garlic yield has been consistently declining, with year-on-year percentage variations showing a consistent downtrend. Notable annual declines include an 8.22% drop in 2015 and an 8.17% decrease in 2020. Even though there was a slight increase of 1.08% in 2021, the overall trend has remained negative. The Compound Annual Growth Rate (CAGR) over the last five years stands at -4.08%, indicating a steady decline in productivity.
Forecasts from 2024 onwards indicate that this declining trend is expected to continue, with a projected CAGR of -4.05% over the next five years. By 2028, the garlic yield is anticipated to decrease further to 18.93 thousand hectograms per hectare, representing an 18.68% decline from 2023 levels.
Future trends to watch for include potential advancements in agricultural practices and technologies that could reverse or stabilize yields. Monitoring climate conditions, soil health, and investment in sustainable farming techniques will be critical in addressing the ongoing decline in garlic yields in Tanzania.
