这项研究揭示了粮食作物专业化和多样化之间的困境。我们使用家庭调查数据来估计作物多样化对八个发展中和转型经济体农村家庭的营养（膳食多样性）和收入（出售的作物）的影响。我们发现，尽管农业对收入的贡献不大，但绝大多数家庭都种植农作物。大多数农业用地用于生产主粮；还生产水果和蔬菜等高价值商品，但数量有限。描述性统计和回归结果都表明，在控制了家庭特征之后，农作物种植数量、家庭农作物收入和我们用于膳食多样性的两个指标之间存在正相关关系。
This study sheds light on the dilemma between food crop specialisation and diversification. We use data from household surveys to estimate the effects of crop diversification on nutrition (dietary diversity) and on income (crops sold) of rural households from eight developing and transition economies. We find that the vast majority of households grow crops despite the modest contribution of agriculture to income. Most agricultural land is devoted to staple food production; high-value commodities such as fruits and vegetables are also produced, but in limited quantities. Both descriptive statistics and regression results show a positive correlation between the number of crops cultivated, household income from crops and the two indicators we use for dietary diversity, also after controlling for household characteristics.
