Extension and advisory services (EAS) are well recognized as a key factor in contributing to agricultural productivity and growth. However, rigorous evaluation of EAS approaches and assessment of complex national or subnational pluralistic EAS systems are rare. This working paper examines the literature on experiential and empirical insights and explores methods to assess complex pluralistic EAS systems. The authors present conceptual thinking on innovation systems and EAS, and review the IFPRI “best-fit” framework. This framework remains relevant because it is based on a holistic perspective with an impact pathway orientation. The paper aims to operationalize and improve the best-fit framework to guide the evaluation of complex EAS systems. The authors draw on and summarize existing literature to illustrate methods and tools used to analyze each component of the framework. The review pays close attention to the literature and methods for assessing the diversity of service providers and their various delivery tools and learning approaches. The discussion also pays close attention to the interaction of each component and how it affects the performance and impact of EAS from a systems perspective. This paper adds key points and considerations on how to operationalize the best-fit framework to carry out evaluations of pluralistic EAS.

Agricultural transformation and development are critical to the livelihoods of more than a billion small-scale farmers and other rural people in developing countries. Extension and advisory services play an important role in such transformation and can assist farmers with advice and information, brokering and facilitating innovations and relationships, and dealing with risks and disasters. Agricultural Extension: Global Status and Performance in Selected Countries provides a global overview of agricultural extension and advisory services, assesses and compares extension systems at the national and regional levels, examines the performance of extension approaches in a selected set of country cases, and shares lessons and policy insights. Drawing on both primary and secondary data, the book contributes to the literature on extension by applying a common and comprehensive framework — the “best-fit” approach — to assessments of extension systems, which allows for comparison across cases and geographies. Insights from the research support reforms — in governance, capacity, management, and advisory methods — to improve outcomes, enhance financial sustainability, and achieve greater scale. Agricultural Extension should be a valuable resource for policymakers, extension practitioners, and others concerned with agricultural development.

As the nature of global malnutrition changes, there is a growing need and increasing urgency for more and better information about food consumption and dietary patterns. The past two decades have seen a dramatic increase in the number, availability, and analysis of the food consumption data collected in a variety of multipurpose household surveys, referred to collectively as household consumption and expenditure surveys (HCESs). These surveys are heterogeneous, and their quality varies substantially by country. Still, they share some common shortcomings in their measurement of food consumption, nutrient intakes, and nutrition status that undermine their relevance and reliability for purposes of designing and implementing food policies and programs. This review crafts a strategic approach to the unfinished global agenda of improving HCESs’ collection of food consumption data. Starting with the priority studies recommended by a 100-country HCES review (Smith, Dupriez, and Troubat 2014), it focuses on a strategic subset of those studies that deal most directly and exclusively with the measurement of food, and that are of fundamental importance to all HCES stakeholders in low- and middle-income countries. Drawing from the literature, this study provides a more detailed, more circumspect justification as to why these particular studies are needed, while identifying key hypotheses, explaining why these studies are of growing urgency, and demonstrating why now is a propitious time for undertaking them. The review also identifies important study design considerations while pointing out potential challenges to successful implementation stemming from technical capacity, economic, administrative, and political considerations. Six key studies are rank ordered from a global perspective as follows, taking into account (1) the likely shared consensus that a topic is an important source of measurement error in estimating consumption; (2) the perceived urgency of the need for addressing a particular source of measurement error; (3) the perceived likelihood of success—that is, that the efforts will improve the accuracy of measurement; (4) whether or not the study entails modifying the questionnaire; (5) the ease with which a study may begin; and (6) the extent to which the study is independent of necessary negotiations with existing HCES stakeholders because of the types of changes it is likely to entail (in either the questionnaire or the way the data have traditionally been processed).

Household consumption and expenditure surveys (HCES) are multipurpose surveys that are routinely conducted to collect data on household food consumption and availability in more than 120 countries. HCES are increasingly being used to calculate proxy estimates of food consumption, nutrient intakes, and nutrition status, often at the individual level. Rarely, however, do they collect information on meal participation, despite growing evidence that it is an increasingly important and variable component of the quantity of food consumed or available in a household. This paper explores the significance of adjusting for meal participation in making inferences about apparent food consumption and nutrient intakes. It focuses on two distinct sets of additional information requirements for enhancing the reliability and precision of measures of food consumption: (1) individual household members’ and household guests’ meal-eating behaviors, and (2) the number and apparent nutritional significance of meals. While the most comprehensive and precise accounting of intakes of individual food consumption and nutrients requires both types of information, the magnitude of the changes required in HCES questionnaires to capture them is likely to be prohibitive. Consequently, for many HCES, a “second best” approach may be the most effective method, at least in the short term. The paper empirically explores some of the relatively few HCES that currently attempt to capture some of these information requirements. In addition, it assesses their value-added to prioritize the global agenda for strengthening HCES measurement of food consumption in support of more evidence-based nutrition policy making.

When and why do suboptimal agricultural policies persist despite technical evidence highlighting alternatives? And what explains episodes of reform after prolonged periods of policy inertia? This paper addresses these questions by applying the Kaleidoscope Model for agricultural and food security policy change to the specific case of agricultural input policy in Zambia. Since 2002, the Farmer Input Support Program (formerly the Fertilizer Support Program) has been a cornerstone of Zambia’s agricultural policy. Over the years, however, many researchers have highlighted weaknesses in the program and proposed other options. Based on semistructured interviews with key stakeholders and intensive process tracing using media, donor, parliamentary, and research reports, this paper examines how the program initially began in 2002 and during subsequent periods of reform in 2009 and 2015. Based on the findings here, periods of reform for input support programs are most likely when there is a confluence of multiple factors. These include the emergence of a window of opportunity in the form of either a focusing event (for example, a food crisis) or an institutional shift (for example, a new president or new ruling party) that coincides with broad stakeholder support for empirically grounded alternatives, available material resources, and sustained commitment from politically important policy makers.

Gold mining is the main economic activity in Madre de Dios, Peru. Despite efforts, the state has not yet managed to identify a formalization process achievable for small operators. In addition, many small-scale miners are driven by poverty and need income to provide for their basic needs. Because participation in small-scale mining is largely driven by poverty, it is likely that, in the longer term, much artisanal mining activity will disappear naturally if, through economic development, more attractive work options become available. This paper reviews the importance of illegal mining in Madre de Dios and the potential for development of the agriculture sector. It also analyzes three different policy scenarios: (1) government spending to rectify the environmental damage in the region caused by illegal mining, (2) development of the agricultural sector in the region, and (3) a final scenario with both environmental restoration and agricultural development. Results show that additional government spending in Madre de Dios does not significantly affect the rest of the country and that investment in agriculture can achieve structural change in the gross domestic product of Madre de Dios. Development of the agricultural sector also slightly increases household incomes in Madre de Dios.

Despite increases in women’s employment, significant gender disparity exists in the time men and women spend on household and care work. Understanding how social expectations govern gender roles and contribute to this disparity is essential for designing policies that effectively promote a more equitable household division of labor. In this study, we examine how a woman’s identity may affect the trade-offs between the time she spends on household and care work and her well-being, using an analytical framework we develop based on the work of Akerlof and Kranton. Analyzing data from rural Bangladesh, we find that longer hours spent on household work are associated with lower levels of subjective well-being among women who disagree with patriarchal notions of gender roles, while the opposite is true for women who agree with patriarchal notions of gender roles. Importantly, this pattern holds only when a woman strongly identifies with patriarchal or egalitarian notions of gender role.

Rising energy expenditures due to more intensive use of energy in modern agriculture and increasing energy prices may affect rural households’ agricultural incomes, particularly the incomes of the rural poor in developing countries. However, the exact link between energy costs and income among the rural poor needs further empirical investigation. This paper aims to gain a deeper understanding of the relationship between energy use and family income, using household-level panel data collected from 500 potato farmers in a poor region of Northern China, where eliminating poverty by 2020 is now the top government priority. The findings indicate that potato plays an important role in the surveyed families’ incomes, and the energy costs of potato production have a significant negative relationship with family income. However, the significance of the negative relationship is robust only for farmers with low economic standing, such as those living below the poverty line or just above it. Energy costs also have a significant negative relationship with the family incomes of those cultivating a certain size of potato-sown area, but this relationship becomes insignificant when farmers have too small of a potato-sown area. These findings indicate that in general, reducing energy costs helps the poor increase their income but is not necessarily helpful to those with high economic standing or a relatively small potato-sown area. If rural development policies are to support poverty reduction and energy savings (at least in major potato production regions), interventions aimed at energy cost reduction may be effective only for the poor whose family income depends, to a relatively high degree, on potato production.

The literature has placed great emphasis on the advantages of competition on market efficiency while ignoring the downside of competition on health. Using a natural experiment in Taiwan, we show that excessive competition comes at a health cost. In the late 1940s, half a million soldiers retreated to Taiwan from Mainland China after a civil war. They were initially not allowed to get married until the marriage ban was essentially lifted in 1959. As a large number of soldiers flooded the marriage market, men faced much stronger mating competition than before, which in turn increased the likelihood of male depression and mortality.

Contract farming (CF) is attractive as a possible private-sector-led strategy for improving smallholder farmers’ welfare. Yet many CF schemes suffer from high turnover of participating farmers and struggle to survive. So far, the dynamics of CF participation have remained largely unexplored. We employ duration analysis to examine factors affecting entry into and exit from different maize CF schemes in northern Ghana, focusing specifically on the impact of development projects on CF entry and exit. We find that agricultural development projects reduce the likelihood of scheme entry and increase the likelihood of exit. Our findings confirm concerns that, if interventions are not planned in accordance with relevant private-sector actors, private-sector initiatives can be hindered by competing development projects.
