Abstract：
In the context of rural Bangladesh, we assess whether agriculture training alone, nutrition Behavior Communication Change (BCC) alone, combined agriculture training and nutrition BCC, or agriculture training and nutrition BCC combined with gender sensitization improve: (a) production diversity, either on household fields or through crop, livestock or aquaculture activities carried out near the family homestead and (b) diet diversity and the quality of household diets. All treatment arms were implemented by government employees. Implementation quality was high. No treatment increased production diversification of crops grown on fields. Treatment arms with agricultural training did increase the number of different crops grown in homestead gardens and the likelihood of any egg, dairy, or fish production but the magnitudes of these effect sizes were small. All agricultural treatment arms had, in percentage terms, large effects on measures of levels of homestead production. However, because baseline levels of production were low, the magnitude of these changes in absolute terms was modest. Nearly all treatment arms improved measures of food consumption and diet with the largest effects found when nutrition and agriculture training were combined. Relative to treatments combining agriculture and nutrition training, we find no significant impact of adding the gender sensitization on our measures of production diversity or diet quality. Interventions that combine agricultural training and nutrition BCC can improve both production diversity and diet quality, but they are not a panacea. They can, however, contribute towards better diets of rural households.
摘要：
在孟加拉国农村，我们评估是否仅农业培训，仅营养行为沟通变化(BCC)，农业培训和营养BCC相结合，或农业培训和营养BCC结合性别敏感性提高：(a)生产多样性，无论是在家庭田地上还是通过作物，在家庭宅基地附近进行的牲畜或水产养殖活动，以及（b）饮食多样性和家庭饮食质量。所有治疗武器均由政府雇员实施。实施质量很高。没有任何处理增加了田间作物的生产多样化。经过农业培训的治疗部门确实增加了在宅基地花园中种植的不同作物的数量以及任何鸡蛋的可能性，乳制品，或鱼类产量，但这些效应大小的幅度很小。所有的农业治疗武器，以百分比计算，对宅基地生产水平的措施有很大影响。然而,因为生产的基线水平很低，这些变化的绝对幅度不大。当营养和农业培训相结合时，几乎所有治疗手段都改善了食物消费和饮食的措施，效果最大。相对于农业和营养培训相结合的治疗方法，我们发现增加性别敏感性对我们的生产多样性或饮食质量没有显著影响.结合农业培训和营养BCC的干预措施可以改善生产多样性和饮食质量，但它们不是灵丹妙药。他们可以,然而,有助于改善农村家庭的饮食。
