Is an integrated farm more resilient against climate change? A micro-econometric analysis of portfolio diversification in African agriculture 总被引:1,自引:0,他引:1
This paper examines whether an integrated farm that owns both crops and livestock is more resilient under global warming than a specialized farm in crops. Using around 9000 farm surveys across Africa, we explore how farmers choose one of the farm types and how the net revenue of each type varies across the range of climate in Africa. The results indicate that an integrated farm increases in number while a specialized farm decreases across Africa under climate predictions for 2060. The relative profitability of each system against each other also changes. An integrated farm becomes relatively more profitable over specialized farms half a century from now. The impacts of climate change on integrated farms range from 9% loss to 27% gain depending on climate scenarios. Behavioral models can capture portfolio diversification benefits that agro-economic models cannot measure. 相似文献

The mandate and competence of the International Monetary Fund (IMF) does not cover food and agriculture policies. While there is anecdotal evidence that the IMF engages in these policies regardless, the state-of-the-art lacks a systematic empirical foundation to identify the extent of its mission creep into these sectors. Based on a combination of machine and human coding, we present a comprehensive database on the IMF’s policy interventions in food and agriculture. Using new data on ‘conditionalities’—policies that governments must implement to access IMF credit—we assess to what extent the IMF has targeted these sectors for the period 1980 to 2014. Our analysis evaluates the agricultural content and ideological orientation of conditions according to whether they promote a developmental state, a night-watchman state, or neither. We find about 2% of all IMF conditions (1105 of 58,406) directly target food and agriculture issues. These are present in 43% of all IMF programs (332 of 781); and affect 100 countries (of the 131 countries that have had an IMF agreement). In addition, our analysis reveals that 59.2% of these conditions embody policy measures in line with night-watchman state policy preferences, 40.1% are model-neutral, and 0.7% developmental. Within the model-neutral category, 23.9% are conditions oriented towards building state capacity; 2.7% have a poverty reduction content; and 2.9% contain pro-environment policies. The IMF’s primary reason for targeting food and agriculture is to enforce fiscal discipline by removing subsidies, yet our analysis identifies that only 8% of these policies abolish subsidies. A more consistent explanation of the IMF’s interest in food and agriculture is its broader mission creep into development policy, and its deep-rooted pro-market ideology. 相似文献

The contribution of women to labor in African agriculture is regularly quoted in the range of 60–80%. Using individual, plot-level labor input data from nationally representative household surveys across six Sub-Saharan African countries, this study estimates the average female labor share in crop production at 40%. It is slightly above 50% in Malawi, Tanzania, and Uganda, and substantially lower in Nigeria (37%), Ethiopia (29%), and Niger (24%). There are no systematic differences across crops and activities, but female labor shares tend to be higher in households where women own a larger share of the land and when they are more educated. Controlling for the gender and knowledge profile of the respondents does not meaningfully change the predicted female labor shares. The findings question prevailing assertions regarding substantial gains in aggregate crop output as a result of increasing female agricultural productivity. 相似文献

East–West union co‐operation in Europe is discussed as the most serious test to cross‐border union solidarity, in the light of new frameworks capable to make sense of transnational trade union activity and alternative to theoretical nationalism. The empirical assessment of trade union chances reviews the activities of trade unions in the UK, Germany, Austria and Poland on foreign investment, migration and movement of services. Secondary evidence and case studies show that the strength of transnational union action does not depend on the country, but rather on its form. ‘Structural’ Europeanization remains weak (e.g. in most European Works Councils), while network‐based action is displaying strong developments, especially on migration, but least on the movement of services. 相似文献

Criteria for assessing the adequacy of a national average diet are proposed, and the global average cereal production per capita needed to provide an adequate average diet is calculated. The technical feasibility of maintaining global food production per capita up to the year 2050 is assessed. The required input of nitrogen fertilizer is estimated and the water supply in relation to crop evapotranspiration is discussed. It is shown that maintenance of the present global cereal production per capita would be accompanied by a moderate increase in grain consumption per capita in the less-developed countries, but that this will involve a major increase in the net import of grain from the more-developed countries. Achievement of a satisfactory average diet in the less-developed countries as a whole cannot be achieved until the population of this group of countries has declined to a level substantially below its future peak. 相似文献

The challenge of organic agriculture – that it might provide new forms of participation around food – has been hard to encapsulate in the conventional circuits of democracy. One answer to this ‘offer’ has been for consumers to purchase organic items as a way of demonstrating support for the organic sector. This paper argues that although this strategy may have been successful in the past, there is increasing evidence that there is a convergence between sections of the organic movement and the dominant multiple retailers. Through a wide range of evidence, including an analysis of how organic products are promoted and of how organic farm businesses are configured, this paper suggests that the potential of the organic movement is increasingly being circumscribed. 相似文献

Rapidly expanding global trade in the past three decades has lifted millions out of people out of poverty. Trade has also reduced manufacturing wages in high income countries and made entire industries uncompetitive in some communities, giving rise to nationalist politics that seek to stop or reverse further trade expansion in the United States and Europe. Given complex and uncertain political support for trade, how might changes in trade policy affect the global food system’s ability to adapt to climate change? Here we argue that we can best understand food security in a changing climate as a double exposure: the exposure of people and processes to both economic and climate-related shocks and stressors. Trade can help us adapt to climate change, or not. If trade restrictions proliferate, double exposure to both a rapidly changing climate and volatile markets will likely jeopardize the food security of millions. A changing climate will present both opportunities and challenges for the global food system, and adapting to its many impacts will affect food availability, food access, food utilization and food security stability for the poorest people across the world. Global trade can continue to play a central role in assuring that global food system adapts to a changing climate. This potential will only be realized, however, if trade is managed in ways that maximize the benefits of broadened access to new markets while minimizing the risks of increased exposure to international competition and market volatility. For regions like Africa, for example, enhanced transportation networks combined with greater national reserves of cash and enhanced social safety nets could reduce the impact of ‘double exposure’ on food security. 相似文献

The development of short supply food chains (SSFCs) is a noteworthy phenomenon in Europe. This paper questions whether these SSFC contribute or not to the preservation and/or development of urban agriculture in the Ile-de-France Region (Paris and surrounding areas), where agriculture still represents a major land use activity (more than 50%). Based on documentary and empirical research the analysis shows that a quarter of farms are involved in SSFC in this region. Taking different forms, these SSFC initiatives are for the majority very recent, they often develop in the frame of hybrid forms of farming. Even though the contribution of SSFC in the total food supply of the Parisian region is poorly informed, and probably very small, the recent interest of consumers, inhabitants, and territorial stakeholders in organic and/or local food is real and has encouraged various types of incentives and commitments. The development of SSFC in the Paris region nevertheless faces numerous obstacles such as the scarcity of land and labour and the environmental impacts that still remain controversial. Promoting the role of SSFCs in the preservation of a sustainable urban agriculture requires access to more statistical and comparative data, which are currently unavailable. 相似文献

We aim to contribute to a better understanding of the dynamics that are driving EU politicization and the rising Euroscepticism of workers and unions in the public sphere. One explanation frames the rise in Euroscepticism in cultural terms, emphasizing workers’ alleged primordial attachment to their nation. A second uses socioeconomic frames, linking growing Euroscepticism to the increasingly neo‐liberal direction of the EU. The weight of these competing frames in the referendum campaigns on the EU Constitution in France and the Lisbon Treaty and the Fiscal Treaty in Ireland cannot be measured easily, as the categorization of a phrase as socioeconomic or cultural is in itself subject to political classification struggles. We therefore presents the findings of an inductive lexical analysis of all Irish Times, all Le Monde and all worker‐ or union‐related articles published in almost all national media outlets during the mentioned referendum debates. This was made possible by the Alceste software package that allowed us to analyse very large corpuses of articles inductively. Our analysis reveals that socioeconomic terms dominated policy debates in both countries. The findings question existing EU politicization studies that were measuring the salience of different frame types by deductive analysis. 相似文献

Increasingly, multi-stakeholder processes have been recognized as being necessary to the development of public policies seeking to promote systemic innovation in response to complex and multidimensional challenges, such as household food security, rural development, and environmental change. Saint Lucia, a small island developing state located in the Caribbean, has been grappling with a wide range of agriculture, food and nutrition security challenges with varying degrees of policy success. Recognizing the significance of the challenge, this paper explores the nature of the stakeholder interactions surrounding the development of Saint Lucia’s 2009–2015 National Agricultural Policy and considers some of the implications for food and agriculture-related policy outcomes. Results reveal a general lack of supportive conditions for effective multi-stakeholder processes, including low stakeholder participation levels, conflicting roles of different forms of social capital in the interactions between stakeholders, and missing “boundary” organizations capable of facilitating a transition towards more flexible and adaptive institutions, enhanced knowledge exchange and learning, and greater trust among stakeholders in the policy network. Future avenues for research and development are subsequently identified. 相似文献

We studied which European Union (EU) economy was more attractive prior to Brexit for employees in supervisory positions. We estimate the extra wage that supervisors earn relative to their subordinates—the wage premium to supervision (WPS)—at different quantiles of distribution of wages for 26 European economies. We find that the UK rewards supervisors more than other EU economies. Moreover, the WPS increases with wage and so increases wage inequality. Over 10% of the WPS depends on the national economic context. We discuss the implications for immigration and policymakers in relation to the post-Brexit process. 相似文献

The number of strategic alliances for R&D activities in the biotechnology industry is sharply increasing. Some studies show that each alliance partner type has different alliance motives, resources and capabilities, organizational structures and cultures, and degrees of competition with partners, which can lead to different performances of strategic alliances. In this regard, this study conducts an empirical analysis of the different impact of each type of alliance partner on technological innovation performance and finds the moderating effect of absorptive capacity and potential competition by categorizing strategic alliances for R&D activities in the biotechnology industry into three types: vertical-downstream alliances, vertical-upstream alliances, and horizontal alliances. This study analyzed 206 Korean biotechnology firms and their strategic alliances for a total of 292 R&D activities. The results of the analysis showed that vertical alliances have a positive impact on technological innovation performance, while horizontal alliances have an inverted U-shaped relationship with technological innovation performance caused by the effect of competition. Additionally, it was confirmed that the R&D intensity of biotechnology firms has a moderating effect of increasing the impact of vertical-upstream alliances on technological innovation performance. 相似文献

Collective trademark and regional product qualification in food-processing industries have become a growing challenge for farmers in developing countries. This challenge is the target of collective action-based programs aiming at framing the cooperation context that would enable a local community to turn inherited resources and know-how into new market opportunities. Literature acknowledges that social capital is a crucial local resource for successful collective actions since it is a source of trust and collective commitment within a community. This paper deals with testing the role of this resource in the collective action case of the cheese producers in Aculco (Mexico). Focusing on the connectedness dimension of social capital, we propose an original methodology that relies on the multiplex and structural properties of social networks. This allows us to disentangle the opposite and ambivalent effects of social capital on the ability of a community to reach the goals assigned by the collective action program. Our empirical study shows that these critical properties can work in favor of adherence to collective action but can also create elite capture, clannish behaviors and entry barriers, thus showing a failure of collective action. 相似文献

This study explores the relationship between corporate social performance (CSP) and corporate financial performance (CFP) within the context of a specific component of CSP: corporate charitable giving. A model of the determinants of the extent of corporate charitable giving is estimated and used as the basis of a classification that groups firms according to the difference between their actual and their predicted intensity of gift giving. The financial performance attributes of the classification are explored. We found that firms with both unusually high and low CSP have higher financial performance than other firms, with unusually poor social performers doing best in the short run and unusually good social performers doing best over longer time horizons.

Consumers play an integral role in the labor process of app-based food delivery services through their consumption behaviors and performance ratings of workers. Some therefore see them as a potential ally of workers, whereas others view them as beholden by capital. This quantitative study uses power resource theory and a Rasch model to appraise consumers' understandings and attitudes toward working conditions in this segment of the “gig” economy. Drawing on two surveys of 1820 Australian consumers, we find that consumers are a potential yet heterogenous coalitional power resource who may align with workers on certain entitlements like minimum wages. 相似文献

Millions of smallholder farmers in developing countries participate in different types of sustainability standards. A growing body of literature has analyzed the welfare effects, with mixed results. Yet, there are important knowledge gaps. First, most existing studies have looked at the effects of one standard in one country. When comparing between studies it is unclear whether dissimilar outcomes are the result of different standards or different local conditions. Second, most studies have used cross-section data, so that selectivity issues remain a challenge. Third, existing work has primarily analyzed effects in terms of purely economic indicators, such as prices and income, ignoring other dimensions of household welfare. We address these shortcomings using panel data from small-scale coffee producers in Uganda and comparing the effects of two of the most popular sustainability standards, namely Organic and Fairtrade. Welfare effects are analyzed in terms of household expenditures, child education, and nutrition. Results show that Organic and Fairtrade both have positive effects on total consumption expenditures. However, notable differences are observed in terms of the other outcomes. Organic contributes to improved nutrition but has no effect on education. For Fairtrade it is exactly the other way around. We explore the mechanisms behind these differences. 相似文献

When do formal control and trust matter? A context-based analysis of the effects on marketing channel relationships in China 总被引:3,自引:0,他引:3

Formal control and trust are two typical governance mechanisms employed to safeguard business transactions. Yet the effectiveness of each mechanism for firm relationship outcomes remains unclear. Some relevant literature suggests that formal control and trust simultaneously can help secure transactions, whereas other research argues the two control mechanisms can substitute for each other. This study applies social embeddedness theory and differentiates strong tie from weak tie relationships. In so doing, it reveals the role of strong versus weak social ties in leading to parallel conclusions about the relationship between formal control and trust and their effects on relationship outcomes. On the basis of empirical tests in a Chinese marketing channels context, this study finds that the joint effects of formal control and trust on governing transactions depends on the relational tie that the focal partners share. Specifically, formal control and trust complement each other only in weak tie relations. On the basis of this new perspective, the authors offer theoretical and managerial implications for managing interfirm governance mechanisms in transitional economies such as China. 相似文献
