Unhealthy foods and tobacco remain the leading causes of non-communicable disease (NCDs). These are key agricultural commodities for many countries, and NCD prevention policy needs to consider how to influence production towards healthier options. There has been little scholarship to bridge the agriculture with the public health literature that seeks to address the supply of healthy commodities. This scoping review synthesizes the literature on government agricultural policy and production in order to 1) present a typology of policies used to influence agricultural production, 2) to provide a preliminary overview of the ways that impact is assessed in this literature, and 3) to bring this literature into conversation with the literature on food and tobacco supply.This review analyzes the literature on government agricultural policy and production. Articles written in English and published between January 1997 and April 2018 (20-year range) were included. Only quantitative evaluations were included. Studies that collected qualitative data to supplement the quantitative analysis were also included. One hundred and three articles were included for data extraction. The following information was extracted: article details (e.g., author, title, journal), policy details (e.g., policy tools, goals, context), methods used to evaluate the policy (e.g., outcomes evaluated, sample size, limitations), and study findings. Fifty four studies examined the impact of policy on agricultural production. The remaining articles assessed land allocation (n = 25) (e.g., crop diversification, acreage expansion), efficiency (n = 23), rates of employment including on- and off-farm employment (n = 18), and farm income (n = 17) among others. Input supports, output supports and technical support had an impact on production, income and other outcomes. Although there were important exceptions, largely attributed to farm level allocation of labour or resources. Financial supports were most commonly evaluated including cash subsidies, credit, and tax benefits. This type of support resulted in an equal number of studies reporting increased production as those with no effects.This review provides initial extrapolative insights from the general literature on the impact of government policies on agricultural production. This review can inform dialogue between the health and agricultural sector and evaluative research on policy for alternatives to tobacco production and unhealthy food supply.

政府政策和农业生产：范围审查，为健康农产品的研究和政策提供信息。

不健康食品和烟草仍然是非传染性疾病 (NCD) 的主要原因。这些是许多国家的关键农产品，非传染性疾病预防政策需要考虑如何影响生产，转向更健康的选择。很少有学术研究将农业与寻求解决健康商品供应问题的公共卫生文献联系起来。本范围界定综述综合了有关政府农业政策和生产的文献，目的是 1) 呈现用于影响农业生产的政策类型，2) 初步概述本文献中评估影响的方式，以及 3)将这些文献与有关食品和烟草供应的文献进行对话。本综述分析了有关政府农业政策和生产的文献。包括 1997 年 1 月至 2018 年 4 月（20 年范围）发表的用英文撰写的文章。仅包括定量评估。还包括收集定性数据以补充定量分析的研究。纳入了一百零三篇文章进行数据提取。提取了以下信息：文章详细信息（例如，作者、标题、期刊）、政策详细信息（例如，政策工具、目标、背景）、用于评估政策的方法（例如，评估结果、样本大小、限制），以及研究结果。五十四项研究考察了政策对农业生产的影响。其余文章评估了土地分配（n = 25）（例如作物多样化、种植面积扩大）、效率（n = 23）、就业率（包括农场内和非农场就业）（n = 18）和农场收入（n = 18）。 = 17）等等。投入支持、产出支持和技术支持对生产、收入和其他成果产生影响。尽管也有重要的例外，但主要归因于农场层面的劳动力或资源分配。最常评估的财政支持包括现金补贴、信贷和税收优惠。这种类型的支持导致报告产量增加的研究与没有影响的研究数量相同。这篇综述从一般文献中提供了关于政府政策对农业生产影响的初步推断见解。该审查可以为卫生部门和农业部门之间的对话以及烟草生产和不健康食品供应替代政策的评估研究提供信息。
