Since 2002, a range of South African policies have attempted to address the disproportionate burden of food and nutrition insecurity on the population. Yet malnutrition among the poor has worsened. This study reviewed policies to examine their implications for food security and the treatment of malnutrition. Policies enacted between 2002 and 2017 were retrieved from government departments and the data were thematically analysed. A preliminary analysis shows that policy has aided production through input provision and capacity building. Taxation, school nutrition programmes and social grants are some of the food access initiatives, whilst micronutrient supplementation, breastfeeding campaigns and food fortification are policies specifically focused on nutrition. However, despite these interventions, food insecurity has remained due to gaps in and contradictions among policies and the lack of coordination in policy development and implementation, especially across sectors. To improve food and nutrition security, government must better engage with ideas about how to address food and nutrition security systemically, and develop the appropriate coordination mechanisms for a more holistic approach to this challenge.
自2002年以来,南非的一系列政策都试图解决粮食和营养不安全给人口带来的不成比例的负担。然而,穷人的营养不良状况已经恶化。这项研究审查了政策,以审查其对粮食安全和营养不良治疗的影响。从政府部门检索了2002年至2017年间颁布的政策,并对数据进行了主题分析。初步分析表明,政策通过提供投入和能力建设帮助了生产。税收、学校营养方案和社会补助金是获得粮食的一些举措,而微量营养素补充、母乳喂养运动和食品强化是专门关注营养的政策。然而,尽管采取了这些干预措施,但由于政策之间的差距和矛盾,以及在政策制定和执行方面缺乏协调,特别是在各部门之间缺乏协调,粮食不安全仍然存在。为了改善粮食和营养安全,政府必须更好地参与如何系统地解决粮食和营养问题的想法,并制定适当的协调机制,以更全面的方式应对这一挑战。

While a large body of literature documents the existence of informal arrangements to share risk across and within households, there has been little research on the various coping strategies through which risk sharing takes place, and how these strategies function. This study attempts to fill this gap in the literature and examine whether, and to what extent, individual labour-supply behaviour is one of such coping strategies used by households facing risk. Our hypothesis is that, as with a small business, individuals adjust their employment behaviour in the event that one of their household members experiences a variation in their labour supply, that is, either gains or loses a job. Using a unique dataset that collects employment histories for each family member in Tanzania, our results confirm our hypothesis and show that the labour supply of the household members is an important determinant of employment transitions, and that these effects are greater for women than for men. In the context of low-income countries, we interpret these findings as evidence that the household works as a risk-sharing institution built around women’s labour supply.
虽然大量文献记录了家庭之间和家庭内部存在非正式的风险分担安排,但很少有关于风险分担发生的各种应对策略以及这些策略如何发挥作用的研究。本研究试图填补文献中的这一空白,并检查个人劳动力供应行为是否是以及在多大程度上是面临风险的家庭使用的这种应对策略之一。我们的假设是,就像小企业一样,如果家庭成员中的一个经历了劳动力供给的变化,也就是说,要么获得了工作,要么失去了工作,个人就会调整自己的就业行为。使用收集坦桑尼亚每个家庭成员就业历史的独特数据集,我们的结果证实了我们的假设,并表明家庭成员的劳动力供应是就业过渡的重要决定因素,并且这些影响对女性比对男性更大。在低收入国家的背景下,我们将这些发现解释为家庭作为一个围绕女性劳动力供应建立的风险分担机构的证据。

Many governments adopt agricultural policies that affect production incentives across commodities. In addition, severe market failures in the form of high marketing margins often lower the prices that farmers receive. Yet the impacts of excessive market-access costs for farmers has not been sufficiently analysed, particularly in sub-Saharan Africa (SSA). Using the newly available FAO/MAFAP dataset, we augment the GTAP model with domestic support and border protection, as well as data on market development gaps (MDGs) in selected SSA countries. We undertake several policy simulations to explore the impacts of changes in excessively high marketing costs. Our findings indicate that addressing MDGs can bring positive overall benefits, with particularly strong gains accruing to sectors and countries with very negative MDGs, such as the non-traditional crops in Ethiopia. In other cases, reducing positive MDGs, which operate as protection of certain sectors from imports, is projected to lead to a decline in exports and output, such as in the case of Ethiopian oilseeds.
许多政府采取的农业政策会影响各种商品的生产激励。此外,由于市场利润率过高,严重的市场失灵往往会降低农民获得的价格。然而,市场准入成本过高对农民的影响还没有得到充分的分析,特别是在撒哈拉以南非洲(SSA)。利用最新的粮农组织/MAFAP数据集,我们在GTAP模型中加入了国内支持和边境保护,以及特定SSA国家的市场发展差距(MDGs)数据。我们进行了几次政策模拟,以探讨过高的营销成本变化的影响。我们的研究结果表明,实现千年发展目标可以带来积极的总体效益,特别是具有非常消极千年发展目标的部门和国家,例如埃塞俄比亚的非传统作物,可以获得特别强劲的收益。在其他情况下,减少积极的千年发展目标——其作用是保护某些部门免受进口——预计将导致出口和产出下降,例如埃塞俄比亚油籽的情况。

This study aimed to analyse the extent to which land- and water-use rights enable/deter the productive use of irrigation water. Data was collected from 242 sampled smallholders in three study areas in KwaZulu-Natal. The findings indicate that the productive use of irrigation water is positively influenced by land- and water-use rights, with scheme committees being the first point of contact for smallholders when they need access to land and water. A provincial body of scheme committees is needed through which smallholders can capacitate each other in how they can improve access, appreciate the role of collective action and deal with challenges related to water, land and markets by applying their experiences. This body can be represented in policy formulation and aid in policy implementation. This paper shows that land and water policy alone cannot improve smallholder productivity, and that enhancing the productive use of irrigation water requires a holistic approach that considers the accessibility of input and output markets.
这项研究的目的是分析土地和水的使用权能在多大程度上促进/阻碍灌溉用水的生产性利用。数据收集自夸祖鲁-纳塔尔省三个研究区的242名抽样小农。调查结果表明,灌溉用水的生产性利用受到土地和水的使用权的积极影响,当小农需要获得土地和水时,计划委员会是他们的第一个联络点。需要一个省级计划委员会机构,通过这个机构,小农可以相互帮助,了解如何改善获取途径,认识集体行动的作用,并通过运用他们的经验来应对与水、土地和市场有关的挑战。该机构可参与政策制定并协助政策执行。本文表明,仅靠土地和水政策不能提高小农的生产力,提高灌溉用水的生产性利用需要一种考虑投入和产出市场可及性的整体方法。

Climate change and heat stress are expected to worsen the issue of water scarcity that is affecting the agricultural sector, among others through increased crop prices and costs, in addition to changes in yields. A crop-mix optimisation model was developed that maximises Egypt’s net revenue while lightening the impacts of climatic change throughout the study period – from 2013 to 2030. The optimal cropping pattern was obtained through iteration of the model on an annual basis using the projected values of the following variables: yield, arable land, costs, prices and consumptive water use. The model is restricted by sets of constraints concerning water and land availability. These variables were projected under different climate-change scenarios using various modelling techniques. The model improves the cropping pattern in Egypt by favouring crops that achieve high profitability while using a small amount of water for irrigation and crops that have a comparative advantage in the above-mentioned variables, while decreasing all crops that are nonprofitable, that use a large amount of water for irrigation, and that are heat intolerant. As a result, the total net revenue is expected to double at the end of the term. The system of models integrated in this study establishes a platform for decision makers to examine different strategies and policies.
除产量变化外,气候变化和高温胁迫预计将使影响农业部门的水资源短缺问题恶化,其中包括农作物价格和成本的上涨。在整个研究期间(从2013年到2030年),开发了一种作物组合优化模型,使埃及的净收入最大化,同时减轻气候变化的影响。利用产量、耕地面积、成本、价格和耗水量等变量的预测值,对模型进行年度迭代,得到最优种植模式。该模型受到有关水和土地可用性的一系列约束的限制。这些变量是在不同的气候变化情景下使用各种模拟技术预估的。该模型改善了埃及的种植模式,有利于灌溉用水少、盈利高的作物和在上述变量上具有比较优势的作物,而减少了所有无利润、灌溉用水多、耐热的作物。因此,总净收入预计将在学期结束时翻一番。本研究整合的模型系统,为决策者检视不同的策略和政策建立了一个平台。

Climate change effects on crop productivity and welfare sensitivity analysis for smallholder farmers in Malawi 气候变化对马拉维小农作物生产力的影响及福利敏感性分析

The effects of climate change on smallholder agriculture under different crop technologies, namely conservation agriculture, Falbedia albida, optimal fertilisation and intensive farming, were analysed against the conventional subsistence farming in Malawi. A biophysical economic modelling approach was used over a 60-year period to assess changes in crop productivity, total welfare and land-use options. The results indicate varying decreases in crop yield. For instance, when compared to the crop yield in 2010, maize yield decreased by -20% under subsistence farming and -0.1% under intensive farming in the seventh decade (2061 to 2070). Adaptation to climate change effects increased total welfare by 24% and producer revenues by 44% when compared to no adaptation. To optimise the welfare of smallholder farmers in Malawi, the study recommends increasing the adoption of intensive farming, conservation agriculture and Falbedia albida to at least 9.5%, 12% and 10% of total cultivated area in the 7th decade respectively. The study also reveals that farmers’ inability to optimise land use has a higher negative impact on welfare when compared to the effect from climate change. This means that the optimisation of crop and technology choices may play a more vital role in improving farmers’ welfare than mere adaptation to climate change.
以马拉维的传统自给农业为例,分析了气候变化对采用不同作物技术的小农农业的影响,即保护性农业、Falbedia albida、最佳施肥和集约化农业。在60年的时间里,使用了生物物理经济建模方法来评估作物生产力、总福利和土地利用选择的变化。结果表明作物产量有不同程度的下降。例如,与2010年的作物产量相比,在第七个十年(2061年至2070年),自给农业的玉米产量下降了-20%,集约化农业的玉米产量下降了-0.1%。与不适应相比,适应气候变化的影响使总福利增加24%,生产者收入增加44%。为了优化马拉维小农的福利,该研究建议在第70个十年中,将集约化农业、保护性农业和苜蓿的采用率分别提高到至少占总耕地面积的9.5%、12%和10%。该研究还表明,与气候变化的影响相比,农民无法优化土地利用对福利的负面影响更大。这意味着,在提高农民福利方面,作物和技术选择的优化可能比仅仅适应气候变化发挥更重要的作用。

This paper evaluates the impact of variety awareness and nutrition knowledge on the adoption of biofortified crop varieties using a sample of 661 households from Kisii and Nyamira counties in Kenya. The study employs the average treatment effect (ATE) framework to control for information on the KK15 bean variety and knowledge of its nutritional attributes among small-scale farmers. The results show that farmers who had knowledge of the nutritional attributes of KK15 beans were more likely to adopt relative to those who were only aware of the variety. A nutrition attribute knowledge gap of 8% was estimated, which represents the potential adoption loss due to a lack of knowledge of the nutritional benefits. Adoption of biofortified crops can therefore be improved by disseminating information on the varieties and their nutritional attributes. This can be achieved by entrenching nutrition information in extension packages disseminated to farmers.
本文以肯尼亚Kisii和Nyamira县的661户家庭为样本,评估了品种意识和营养知识对采用生物强化作物品种的影响。本研究采用平均处理效应(ATE)框架控制小农对KK15豆品种信息及其营养属性的了解。结果表明,了解KK15豆类营养特性的农民比只了解该品种的农民更有可能采用KK15。据估计,营养属性知识缺口为8%,这代表了由于缺乏对营养益处的了解而导致的潜在采用损失。因此,可以通过传播有关品种及其营养特性的信息来改进生物强化作物的采用。这可以通过在向农民分发的推广包中加强营养信息来实现。

Smallholder rural farmers are exposed to diverse idiosyncratic and covariate shocks that lead to high income and consumption volatility. Formal cash management tools, which are important for managing risk and volatility, often break down due to high information asymmetries and the transaction costs of operating in rural areas. Given this, community-based cash management tools have continued to be a dominant means of managing risk in rural areas. Community-based cash management tools can be home grown or externally induced, e.g. NGO-initiated savings groups. This study finds that participation in such savings groups significantly expands access to the financial resources that can be used to purchase goods and services, as well as to the social networks that are needed to support smallholder farmer livelihoods. However, the impact on access to physical and natural capital (at least in the short to medium term) is not significant, thus calling for complementary development interventions to reduce smallholder farmers’ vulnerability.
农村小农面临不同的特质和协变量冲击,导致高收入和消费波动。正规的现金管理工具对管理风险和波动性很重要,但由于信息高度不对称和在农村地区开展业务的交易成本,这些工具往往失效。有鉴于此,以社区为基础的现金管理工具继续是农村地区管理风险的主要手段。以社区为基础的现金管理工具可以是本地开发的,也可以是外部诱导的,例如非政府组织发起的储蓄小组。本研究发现,参加此类储蓄团体大大扩大了获得可用于购买商品和服务的金融资源的机会,以及支持小农生计所需的社会网络。然而,对获得物质和自然资本的影响(至少在短期到中期)并不显著,因此需要采取补充性发展干预措施,以减少小农的脆弱性。

Using an original database from French archives on French trade statistics, this article undertakes a comprehensive study of the nature and dynamic of French sectoral trade for the period 1880 to 1912. The results highlight a common trend regarding Franco-colonial trade compared to French trade with non-French colonies. In particular, we found that French trade with its colonies was based mainly on imports of primary products and exports of manufactured goods, meaning that the Empire was used as the main dispenser of French exports and the country’s main provider of natural resources. Statistics also emphasise that the event of colonisation was followed by an increase in trade between France and its own colonies, while colonisation by Britain and other colonising countries did not affect trade between France and non-French colonies. The article finally reveals that trade with French colonies was unbalanced and unidirectional, without any advantage in favour of those colonies.
本文利用法国贸易统计档案的原始数据库,对1880年至1912年期间法国部门贸易的性质和动态进行了全面研究。与法国与非法国殖民地的贸易相比,结果突出了法国殖民地贸易的共同趋势。特别是,我们发现法国与其殖民地的贸易主要基于初级产品的进口和制成品的出口,这意味着帝国被用作法国出口的主要分配者和该国自然资源的主要提供者。统计数据还强调,殖民事件之后,法国与自己的殖民地之间的贸易增加,而英国和其他殖民国家的殖民并没有影响法国与非法国殖民地之间的贸易。文章最后揭示了与法国殖民地的贸易是不平衡和单向的,没有任何有利于这些殖民地的优势。
