“…Results are however, in contrast with the findings of [11] who reported that specialization impacts negatively on productivity of smallholder farmers in Papua New Guinea. [1,11,12,16,25,28] also reported in the same line. Their findings revealed that diversification impacts positively on the TEs of vegetable-based cropping systems in South Africa, tomato production in Oyo (Nigeria), small-scale dry season vegetable farmers in Sokoto (Nigeria), peasant farmers in Nigeria, and multiple crop farmers in Vietnam respectively.…”

This study evaluated the efficiency of diversification versus specialization of vegetable-based farms in the West region of Cameroon. The study employed the use of a questionnaire to obtain information from 70 specialized and 54 diversified farmers randomly selected from three purposively selected localities in the West region. The one-step stochastic frontier approach with a Cobb-Douglas model specification was used in analysis. Data was analyzed using the computer program, STATA version 12.0. Findings revealed that majority (71.8%) of vegetable farmers are males, with an average age of 30 years and 73.4% had attained at least a primary education. Results of the stochastic frontier analysis revealed the mean technical efficiency of vegetable farmers to be 0.863. Mean technical efficiency scores for specialized and diversified farmers were found to be 0.867 and 0.858 respectively. However, the results of a standard t-test concluded that technical efficiency is invariant of cropping system. The main sources of inefficiency were identified to be farm size, education, credit and membership to a mutual aid group, while age, sex and access to extension information and services were found to enhance technical efficiency. The study therefore recommends extension services to be reinforced on farmers who receive loan and on those who belong to mutual aid groups, in a bid to increase technical efficiency.

“…Makate et al (2016) argued that diversified cropping systems primarily reduce crop production risks by providing more income options to the farmer, therefore, making production on the farm more stable. Our finding that more diversified farms are more efficient is consistent with Nguyen (2014), Manjunatha et al (2013), Ogundari (2013), Rahman (2009) and Coelli and Fleming (2004) for Vietnam, India, Bangladesh, Nigeria and Papua New Guinea, respectively.…”

Hope for Change: Is Diversifying Production Portfolios an Ideal Strategy to Boost Farming Efficiency in Afghanistan?

In this article, I present empirical evidence on the extent of crop diversification and assess its merits as a strategy for improving production efficiency in Afghanistan. The transformed Herfindahl–Harshman index is used to measure the scale and magnitude of crop diversification. I find a compelling evidence that diversifying production portfolios significantly improves production efficiencies. This finding is critical, given that the data show that nearly a third of the farm households do not diversify, achieving, on average, about 52% of potential revenues. The estimated efficiency scores reveal that, on average, the farm households in our analytical sample of over 7,000 households achieve 74% of potential revenue, with nearly 15% of households realizing less than 50% and about 23% between 50% and 70% of potential revenue. These results infer that there exist substantial inefficacies in agricultural production that can be eliminated by employing improved management practices without having to use additional inputs and production resources and rising cost of production. Our results are robust to potential endogeneity bias in crop diversification; I account for the endogeneity problem in the stochastic frontier analysis, by employing a recent estimation approach, using instrumental variable techniques. Mapping the spatial distribution of crop diversification index and estimated efficiency scores across the country revealed that districts with higher diversification levels correspond to higher efficiency indices. Aside from crop diversification, other socio-economic factors also have critical implications for efficiency; households with access to farm assets (such as land, cattle, oxen and tractor) and extension services appear to realize substantially higher production efficiencies. A direct policy recommendation that can be generated from the findings of this study is that crop diversification should be given more recognition by policymakers to enhance productivity and resilience in agriculture.

“…Kidane and Zegeye (2018) contended that management of crop diversification is complex and requires appropriate skills and input as compared to specialized production. In Vietnam, Nguyen (2014) established a substantial inefficiency resulting from multiple crop production, which causes production loss of close to 20%. However, this finding contrasts with the study by Bangwayo-Skeete et al (2012).…”

PurposeThis paper aims to analyze the effects of crop specialization on agricultural productivity and commercialization for farmers who produce high-value crops in the Northern Savannah Ecological Zone of Ghana.Design/methodology/approachThe study used the USAID/Ghana Feed the Future (FTF) survey, which collected data on high-value crops (i.e. maize, rice and soya). Data for the analysis consists of 2,903 farm households. The study utilized the three-stage generalized method of moment estimation technique to deal with the potential endogeneity of crop specialization within the context of productivity and commercialization and heteroscedasticity issues in the data.FindingsThe study found that crop specialization positively relates to agricultural productivity and commercialization, suggesting that increased crop specialization in the production of high-value stimulates productivity and opens market opportunities for farm households. These findings imply that crop specialization seems more beneficial to farmers as it significantly improves productivity and commercialization.Research limitations/implicationsThe study was conducted in the Northern Savannah Ecological Zone of Ghana and not the entire country.Originality/valueTo the best of the authors' knowledge, this study is the first to have jointly modeled crop specialization, agricultural productivity and commercialization. The main advantage of using this system approach is that it uses more information, thereby providing more precise parameter estimates.
