Mechanization in Ghana: Searching for sustainable service supply models:

This paper assesses the sustainability of the current supply network for mechanization, given government policy. Stylized models of mechanization supply are developed based on experience in Bangladesh, China, and India during similar stages of agricultural transformation. Ghana’s supply network is then analyzed in light of key lessons from the Asian experience. The analysis focuses on two policy issues: (1) whether the current model promoted by the government has left enough room for the private sector to develop the supply chain, including machinery imports and trade, and (2) whether this model can better link smallholders’ demand for mechanized services to its supply, such that supply can further induce demand and mechanization can broaden its role in agricultural transformation.

Agricultural mechanization in Ghana: Is specialization in agricultural mechanization a viable business model?

The Government of Ghana (GoG) since 2007 has been providing subsidized agricultural machines to individual farmers and private enterprises established as specialized Agricultural Mechanization Services Enterprise Centers (AMSECs) to offer tractor-hire services to small-scale farmers across the country. Current demand in the country is primarily focused on land preparation services, especially plowing. This paper assesses whether AMSEC enterprises are a viable business model attractive to private investors. Using firm investment theory and field-based data on costs, revenues, and tractor efficiency, this research examines the profitability of specialized agricultural mechanization service provision with a focus on land preparation. Findings suggest that the AMSEC model is not a viable business model, even with the current level of subsidy. Low operational scale is the most important constraint to the profitability of investment in specialized agricultural mechanization service provision. With such a low operational scale, it is essential to consider various options for introducing low-cost, small tractors suited to the current farming scale in the country. Also, a used tractor model is one of the options available for policymakers in the country. Tractor-hire services can play an important role in transforming smallholder agriculture, but with heavy subsidies on big and costly tractors, the subsidy policy can distort supply chain development. As a result, many better-suited and lower-cost machines are unlikely to be introduced into local markets.

Farm transition and indigenous growth: The rise to medium- and large-scale farming in Ghana

This paper characterizes the transition from small-scale farming and the drivers of farm size growth among medium- and large-scale farmers in Ghana. The research was designed to better understand the dynamics of change in Ghana’s farm structure and contribute to the debate on whether Africa should pursue a smallholder-based or large-scale oriented agricultural development strategy. The results suggest a rising number of medium-scale farmers and a declining number of smallholder farmers in the country, a pattern that is consistent with a changing farm structure in the country’s agricultural sector. More important, findings show that the rise to medium- and large-scale farming is significantly associated with successful transition of small-scale farmers rather than entry of medium or large farms into agriculture, reflecting small-scale farmers successfully breaking through the barriers of subsistence agriculture into more commercialized production systems. The findings in this paper also suggest that some of the factors thought to be important for change in farm structure are no obstacle to farm size growth, even though they may foster transition. Notably, the results here diverge from the patterns observed in Zambia and Kenya, which indicate that the emergent farmers came mostly from the urban elite. Unfortunately, past and current policy discussions have not featured these emergent farmers sufficiently in the quest to transform agriculture in Ghana. Government should capitalize on these emergent farmers who have a demonstrated ability to graduate productively as it strives to address challenges in the smallholder sector.

Changes in Ghanaian Farming Systems: Stagnation or a Quiet Transformation?

This research was designed to understand better the patterns of agricultural intensification and transformation occurring in Africa South of the Sahara using the Ghanaian case. The paper examines changes in farming systems and the role of various endogenous and exogenous factors in driving the conversion of arable lands to agricultural uses in four villages within two agroecologically distinct zones of Ghana: the Guinea Savannah and Transition zones. Using essentially historical narratives and land-cover maps supplemented with quantitative data at regional levels, the research shows that farming has intensified in the villages, while farmers have increased their farm size in response to factors such as population growth, market access, and changing rural lifestyle. The overall trend suggests a gradual move toward intensification through increasing use of labor-saving technologies rather than land-saving inputs—a pattern that contrasts with Asia’s path to its Green Revolution. The findings in this paper provide evidence of the dynamism occurring in African farming systems; hence, they point toward a departure from stagnation narratives that have come to prevail in the debate on agricultural transformation and intensification in Africa South of the Sahara. We conclude that it is essential for future research to expand the scope of this work, while policies should focus on lessons that can be learned from these historical processes of genuine change.

How Can African Governments Reach Poor Farmers with Fertiliser Subsidies? Exploring a Targeting Approach in Ghana

Abstract African governments have been pursuing reforms to improve the targeting of fertiliser subsidy programmes, but recent experience suggests that these reforms have not ensured that subsidies reach intended beneficiaries. Using a targeting approach based on proxy means tests with carefully selected indicators, this paper suggests that Ghana’s fertiliser subsidy programmes can be targeted to the country’s poor and smallholder farmers more efficiently and more cost-effectively. While a universal subsidy in 2012 is estimated to have reached 11 per cent of poor farmers, the proposed targeting approach would have reached 70 per cent of the poor farmers in northern Ghana and 50 per cent of poor farmers in southern Ghana. Targeting reduces the costs of leakages by about 72 per cent, thus justifying the costs of administering targeted programmes using the poverty proxies. Furthermore, we show that once the initial models are constructed, the targeting approach can be used for nearly 20 years without any significant losses in accuracy. We propose that policy-makers should consider implementing this targeting approach on a pilot scale involving a few communities and, if found successful in practice, in a larger-scale programme.
