Agricultural TFP Growth and Food Security in Southern Africa (2000-2025)

Bornwell Mutale's dataset contains a balanced panel of 260 country-year observations for 10 SADC nations from 2000 to 2025. It includes agricultural Total Factor Productivity (TFP) indices, growth rates, decomposition components, nine regression determinants, and two food security indicators. The data combines observed values (2000-2020) with projected values (2021-2025) and is structured across seven worksheets for analysis and replication.

Use Cases

• Decomposing agricultural output growth into input contributions and TFP residual using the provided growth accounting results.
• Analyzing determinants of TFP growth via panel regression with variables like government investment, trade openness, and climate anomalies.
• Tracking trends in food security indicators such as undernourishment prevalence and dietary energy supply across SADC countries.
• Comparing technical efficiency change and technological change components of TFP across countries and over time.
• Replicating econometric models (Pooled OLS, FE, RE, 2SLS) for the study of agricultural productivity determinants.

Strengths

• Provides a balanced panel of 260 observations, ensuring consistent coverage across 10 countries and 26 years.
• Includes both observed data (2000-2020) and clearly flagged projected data (2021-2025), extending the analysis horizon.
• Contains a detailed codebook for 25 variables and seven structured worksheets supporting full analysis replication.

Limitations

• Projections for 2021-2025 are based on OLS trend extrapolation from a short 2016-2020 base period, which may reduce reliability.
• The exact row count for the primary dataset is not explicitly stated in the provided metadata.
• Data freshness is limited for projections, as the underlying source data is from 2023.
