Download Is There a Farm-Size Productivity Relationship in African Agriculture? Evidence from Rwanda Book in PDF, ePub and Kindle
Whether the negative relationship between farm size and productivity that is confirmed in a large global literature holds in Africa is of considerable policy relevance. This paper revisits this issue and examines potential causes of the inverse productivity relationship in Rwanda, where policy makers consider land fragmentation and small farm sizes to be key bottlenecks for the growth of the agricultural sector. Nationwide plot-level data from Rwanda point toward a constant returns to scale crop production function and a strong negative relationship between farm size and output per hectare as well as intensity of labor use that is robust across specifications. The inverse relationship continues to hold if profits with family labor valued at shadow wages are used, but disappears if family labor is rather valued at village-level market wage rates. These findings imply that, in Rwanda, labor market imperfections, rather than other unobserved factors, seem to be a key reason for the inverse farm-size productivity relationship.

Agricultural Productivity in Africa: Trends, Patterns, and Determinants presents updated and new analyses of land, labor, and total productivity trends in African agriculture. It brings together analyses of a unique mix of data sources and evaluations of public policies and development projects to recommend ways to increase agricultural productivity in Africa. This book is timely in light of the recent and ongoing growth recovery across the continent. The good news is that agricultural productivity in Africa increased at a moderate rate between 1961 and 2012, although there are variations in the rate of growth in land, labor, and total factor productivities depending on country and region. Differences in input use and capital intensities in agricultural production in the various farming systems and agricultural productivity zones also affect advancements in technology. One conclusion based on the book’s research findings derives from the substantial spatial variation in agricultural productivity. For areas with similar agricultural productivity growth trends and factors, what works well in one area can be used as the basis for formulating best-fit, location-specific agricultural policies, investments, and interventions in similar areas. This finding along with others will be of particular interest to policy- and decisionmakers.

This paper proposes a new interpretation of the farm size-productivity relationship. Using two rounds of the Ethiopian Rural Household Survey, and drawing on earlier work on five countries in Sub-Saharan Africa, the paper shows that the relationship between farm size and productivity is neither monotonic nor univocal. Most previous studies that tested the inverse farm size-productivity relationship used ordinary least squares estimation, therefore reporting parameter estimates at the conditional mean of productivity. By expanding these important findings to consider the entire distribution of agricultural productivity, the analysis finds sign switches across the distribution, pointing to a "direct-inverse-direct" relationship. Less productive farmers exhibit an inverted U-shape relationship between land productivity and farm size, while more productive farmers show a U-shape relationship that reverses the relationship. In both cases, the relationship points toward a threshold value of farm size; however, the threshold is a minimum for the less productive farmers and a maximum for the more productive ones. To the left of the threshold, for very small farmers, the relationship between productivity and farm size is positive; for the range of middle farm size, the relationship is negative; and to the right of the threshold, the relationship is direct (positive) again. From a policy perspective, these findings imply that efficiency-enhancing and redistributive land reform should consider farm size in the proper context of the present and potential levels of agricultural productivity. The results and their policy implications underline the relevance of the most recent efforts of the international development community to collect more reliable georeferenced data on farm size and agricultural productivity.

Download The Relationship Between Farm Size and Efficiency in South African Agriculture Book in PDF, ePub and Kindle
November 1995 Commercial farms in South Africa could become significantly more efficient if they became smaller. The government could encourage that trend by removing policies and distortions that favor large over small farms. Drawing on international evidence, van Zyl, Binswanger, and Thirtle discuss the sources of economies of scale. Using representative farm-level survey data for South Africa's six major grain-producing areas and one irrigation area for the period 1975 - 90, they: * Describe the structure of South African agriculture, detailing the distribution of farm sizes and results from previous studies of farm-size efficiency. * Analyze the evidence on scale efficiency in the former homelands. * Analyze the relationship between farm size and efficiency in commercial farming and discuss how policy affects that relationship. Clearly policy has a crucial impact on the relationship between farm size and efficiency. They find that: * Farms in the former homelands seem to be scale-inefficient, which is unsurprising, given the historical lack of access to support services and infrastructure, policies that discriminate against farmers in the homelands, and the extremely fragmented and limited land-use rights of farmers there. * There is an inverse relationship between farm size and efficiency in the commercial farming areas for the range of farms analyzed, regardless what method is used. This inverse relationship seems to become stronger and more accentuated as policy distortions -- which tend to favor large farms over small ones -- are removed. * Large farms tend to use more capital-intensive methods of production, while smaller farms are more labor-intensive. And managerial ability seems to be better on larger farms. There is an inverse relationship between farm size and efficiency in South African agriculture despite South Africa's history of policies favoring relatively large mechanized farms. Clearly, efficiency gains could be significant if commercial farms became smaller. To encourage that trend, policies and distortions that favor large farms over small should be removed. This paper -- a product of the Office of the Director, Agriculture and Natural Resources Department -- is part of a larger effort in the department to design appropriate strategies for land reform.

Enhancing the productivity of agriculture is vital for Sub-Saharan Africa's economic future and is one of the most important tools to end extreme poverty and boost shared prosperity in the region. How governments elect to spend public resources has significant development impact in this regard. Choosing to catalyze a shift toward more effective, efficient, and climate-resilient public spending in agriculture can accelerate change and unleash growth. Not only does agricultural public spending in Sub-Saharan Africa lag behind other developing regions but its impact is vitiated by subsidy programs and transfers that tend to benefit elites to the detriment of poor people and the agricultural sector itself. Shortcomings in the budgeting processes also reduce spending effectiveness. In light of this scenario, addressing the quality of public spending and the efficiency of resource use becomes even more important than addressing only the level of spending. Improvements in the policy environment, better institutions, and investments in rural public goods positively affect agricultural productivity. These, combined with smarter use of public funds, have helped lay the foundations for agricultural productivity growth around the world, resulting in a wealth of important lessons from which African policy makers and development practitioners can draw. 'Reaping Richer Returns: Public Spending Priorities for African Agriculture Productivity Growth' will be of particular interest to policy makers, development practitioners, and academics. The rigorous analysis presented in this book provides options for reform with a view to boosting the productivity of African agriculture and eventually increasing development impact.

"This paper considers the relationship between farm size and productivity. It begins by discussing measurement issues and conceptual issues related to agricultural productivity, including the well-documented difficulty of measuring inputs and outputs in smallholder production systems. The paper then considers the relationship between farm size and productivity, documenting patterns both across countries and within countries. Across countries, there is a weak but positive relationship between farm size and the value of agricultural output per unit of land (i.e. yield). A much stronger positive relationship holds for agricultural output per unit of labour, which is closely correlated with farm size across countries. Within countries, the relationship between farm size and yield is often negative (the widely documented 'inverse farm size-productivity relationship'). However, even within countries, there is typically a strong positive relationship between farm size and labour productivity. The paper concludes by considering the policy implications, if any, of the relationships between farm size and agricultural productivity"--Page 4.

This paper argues that partial productivity measures are inappropriate and at times misleading for assessing the performance of agricultural production technologies and systems. This is especially true where substantial changes in resource stock and flows accompany the production process. Superlative-index based total factor productivity measures are a more appropriate technique to compare production efficiency and sustainability of alternative systems. Mathematical formulations of intertemporal and interspatial total factor productivity measures with and without considering changes in resource stock and flows are shown. Then three case studies from sub-Saharan Africa in which this approach was applied are reviewed. These studies show that total factor productivity measures are biased if changes in resource stock and flows are not appropriately accounted for in intertemporal comparisons, and differences in input intensity are not accounted for in interspatial comparisons.
