Technical efficiency and technological gaps among smallholder beef farms in Botswana: a stochastic meta-frontier approach POLICIES FOR COMPETETIVE SMALLHOLDER LIVESTOCK PRODUCTION 4-6 MARCH 2015, GABORONE, BOTSWANA Sirak Bahta International Livestock Research Institute (ILRI)

Agriculture in Botswana: The main source of income and employment in Rural areas (42.6 percent of the total population) 30 percent of the country’s employment More than 80 percent of the sector’s GDP is from livestock production Cattle production is the only source of agricultural exports Background 1
3
Dualistic structure of production, with communal dominating Background (Cont.) Cattle population 2
4
Background (Cont.) Despite the numerical dominance, productivity is low esp. in the communal/traditional sector 3
5
Growing domestic beef demand and on-going shortage of beef for export: In recent years beef export has been declining sharply (e.g. from 86 percent of beef export quota in 2001 to 34 percent in 2007 (IFPRI, 2013 )) Background (Cont.) 4
6
To measure farm-specific TE in different farm types and analyze the determinants of farmers’ TE To measure technology-related variations in TE between different farm types To Come up with policy recommendations to improve competitiveness of beef production Objective of the study 5
7
Measuring efficiency Measuring efficiency: potential input reduction or potential output increase relative to a reference (Latruffe, 2010). Technological differences Comparison of farms operating with similar technologies. However, farms in different environments (e.g., production systems) do not always have access to the same technology. Assuming similar technologies = erroneous measurement of efficiency by mixing technological differences with technology-specific inefficiency. Meta-frontier Enables estimation of technology gaps for different groups It captures the highest output attainable, given input (x) and common technology. 6

14
-The majority of farmers use available technology sub-optimally and produce far less than the potential output; average MTR is 0.756 and TE is 0.496. -Herd size, Controlled cattle breeding method, access to Agric and non Agric income, market contract (BMC), herd size and farmers’ age all contribute positively to efficiency. -On the contrary, indigenous breed, distance to markets and income and formal education did not have a favorable influence on efficiency. Conclusion and policy implications 13
15
Conclusion and policy implications 14 -It is important to provide relevant livestock extension and other support services that would facilitate better use of available technology by the majority of farmers who currently produce sub-optimally. -Necessary interventions, for instance, would include improving farmers’ access to appropriate knowledge on cattle feeding methods and alternative feeds. -Provision of relatively better technology (e.g., locally adaptable and affordable cattle breeds and breeding programmes).
16
-Access to market services, including contract opportunities with BMC. -Provide appropriate training/education services that enhance farmers’ management practices. - Policies that promote diversification of enterprises, including creation of off-farm income opportunities would also contribute to improving efficiency among Botswana beef farmers.

Metafrontier This technique is preferred in the present study because : -Enables estimation of technology gaps for different groups -Accommodates both cross-sectional and panel data The stochastic metafrontier estimation involves first fitting individual stochastic frontiers for separate groups and then optimising them jointly through an LP or QP approach. - It captures the highest output attainable, given input (x) and common technology. 7 Measuring efficiency
