The concepts of resource frontier and commodity frontier are often treated interchangeably. This article suggests the benefits of clarifying these concepts because frontiers remain important analytics for understanding drastic land‐use changes and other socio‐environmental transformations. Based on long‐term field research in different parts of South and Central America, we use frontier concepts as heuristic devices to analyze heterogeneous frontier situations and make broader generalizations. Our synchronic and diachronic analyses of frontier dynamics elucidate different frontier modalities and shifting frontier expansions. The concept of commoditizing resource frontier is introduced to explain recent frontier‐makings in Brazilian Amazonia and Cerrado and in the Nicaraguan Río San Juan. Although earlier frontier research took a short‐term time perspective and created conceptualizations based on a single modality of a particular period, our longitudinal analysis shows that drastic changes and complex overlappings are the hallmarks of frontier dynamics.  相似文献

This research explores the role of agrarian and environmental movements in contesting the development and promotion of agricultural biotechnology through trade liberalization in Latin America. Organized around themes of mobilization, participation and representation, it raises key questions about who mobilizes and how, and about the strategic dilemmas that arise when movements with different histories, membership bases and cultures of protest attempt to work together. Issues of accountability, representation and participation run through the analysis of strategies of organization and claim-making adopted by an eclectic range of groups seeking to contest the role of biotechnology in the structure of agricultural production, the institutions that manage that relationship and the discourses which sustain it. In particular, analysis centres on their responsiveness to the concerns and agendas of poorer groups in the front line of the 'gene revolution' as it plays out in the Latin American countryside, in particular in Argentina and Brazil, the key players in biotechnology in the region.  相似文献

Rural Poverty and Development Strategies in Latin America   总被引:3,自引:3,他引:3  
Several approaches to the study of poverty are discussed, to learn from their strengths as well as their weaknesses. For this purpose the concepts of marginality, social exclusion, new rurality and rural livelihoods, as well as the ethnic and gender dimensions of poverty, are examined. The debate on the peasantization (capitalization) or proletarianization (pauperization) of the peasantry sets the scene for the analysis of the different strategies adopted by peasants and rural labourers to secure their survival and perhaps achieve some prosperity. In examining the success or failure of interventions by governments, civil society and international organizations in the reduction of poverty, it is claimed that the State has a key role to perform. Furthermore, it is argued that poverty is caused and reproduced by the unequal distribution of resources and power at the household, local, national and international levels. Therefore, the starting point for the eradication of poverty has to be the implementation of a development strategy that addresses such inequalities while at the same time achieving competitiveness within the global system.  相似文献

The unrestricted international flow of genetic resources from international genebank collections is the source of perhaps one of the greatest impacts of international agricultural research. This paper examines the distribution across countries in Latin America of benefits generated from bean genetic resources held by the International Center for Tropical Agriculture (CIAT). The genealogies of commercial bean cultivars released since 1976, containing materials from the collection, are analysed to calculate for each country the source of the genetic resources used. All countries in the region are shown to be heavily dependent on imported genetic resources for their commercial cultivars. From the available information on the economic impact of these improved bean varieties, the share of economic productivity benefits associated with imported germplasm by country of origin is calculated. The benefits received by each country from improved bean germplasm are compared with the contribution of that country's germplasm to other countries. Some of the patterns in the flow and use of genetic resources are analysed.  相似文献

Latin America has a long and rich history of land administration projects stretching back to the 1980s and beyond. Unfortunately, this history has not been systematically analyzed nor recorded but is buried in a myriad of reports and other gray literature. Currently, almost every country in the region has a land administration project, incorporating cadastral reform, that is either in preparation or being implemented. It is therefore timely to consider what lessons have been learned from previous experience, in the region and elsewhere, and more specifically how this experience can inform current efforts. This paper starts with a summary of a recent World Bank/USAID initiative to compile lessons learned from land administration projects around the world and follows with the author's view of lessons learned in the context of project design, institutional reform and technical innovation.  相似文献

This article examines the expansion of the soybean complex in South America and the role of Chinese firms in expanding their presence in different sectors of the oilseed complex. The growth in trade relations between the two parties has been built on the export of primary commodities from South America and the import of Chinese manufactures—a trade pattern that reproduces core‐periphery dynamics identified by dependency theory scholars. Of particular importance in this bilateral trade is soybean, a crop that has been consolidated as the main export for several South American countries, fuelled by growing demand from China. This article explores China's role in the global political economy as a key agri‐business player and the implications for new relations of dependency by studying the strategies deployed by Chinese firms to increase their influence in the governance of the soybean nexus.  相似文献

Around two‐thirds of the global population will live in cities by 2050 requiring large urban infrastructure development. Decision‐makers and planners usually rely on standard economic accounting methods for urban planning and investments on infrastructure assets. However, standard methods fail to account for the ecosystem services benefits that living infrastructure (e.g. urban forests, open spaces) provides to city dwellers. This could generate socially inefficient configurations of urban spaces and compromise the achievement of long‐term urban sustainability targets. In this analysis, we applied a stochastic whole‐of‐life benefit–cost analysis following the System of Environmental‐Economic Accounting (SEEA) framework to compare alternative long‐term management strategies for living infrastructure in Canberra, Australia. Spatially explicit data, i‐Tree Eco and benefit transfer methods were used to estimate the stocks and flows ecosystem services benefits of urban forests and irrigated open spaces from 2018 to 2070. Our analysis suggests that a ’30 per cent canopy cover expansion’ scenario has the highest benefit–cost ratio, while the business as usual scenario, where a net loss of 400 trees is expected per year, offers the lowest benefit–cost ratio. Scenarios of expanding versus not expanding irrigated open spaces in the future both result in a benefit–cost ratio of approximately two.  相似文献

We model Central American migrant-sending household agricultural practices given labor losses and the concomitant infusion of remittances. Under the new economics of labor migration (NELM) framework, it is hypothesized that smallholder farm households invest remittance income in their land either to increase crop production or to transition to cattle ranching. We test this hypothesis by developing a combination of multivariate logistic, Poisson and beta regression techniques using Latin American Migration Project data to determine how agricultural land use change compared among migrant and non-migrant households in Costa Rica, El Salvador, Guatemala, and Nicaragua. Results indicate that a rise in months spent abroad and remittances returned do not translate into a higher percentage of farm sales, intensification or transition to cattle ranching – counter to NELM. However, farmers are investing remittances to increase row crop and pasture land holdings. These findings suggest remittance investments in quantitative increase rather than qualitative change in land use practices. Given the expansive land demands supporting low intensity smallholder agriculture and cattle, and the land degradation cattle precipitate particularly, the trend does not augur well for the sustainability of rural landscapes increasingly transformed by international remittances. Appropriate policies to champion coupled human-land system sustainability in Central America might usefully consider viable land use alternatives to remittance investments dedicated to crop and pasture expansion.  相似文献

Gastronomy has been established as one of the key elements for the promotion and consolidation of tourist destinations. The current aim is to contribute to the scientific literature in the field of the relationship between gastronomy and tourism in Latin America from the experience affirmed by North American tourists in the city of Cuenca (Ecuador). The methodology is based on a questionnaire presented to North American travelers during their visit to the city of Cuenca. The results show the existence of different segments of tourists in relation to their attitude toward the local gastronomy. Three segments are identified, and depending on their belonging to a certain segment, the tourists have different motivations with respect to gastronomy. Finally, the results permit concluding that the levels of satisfaction of the tourists differ depending on their attitude toward gastronomy, identified by the three segments.  相似文献

Paying Indigenous communities to conserve land for carbon sequestration is a controversial way of tackling climate change. Critics argue that paying for ecological services (or ‘PES’) in the form of carbon offset programmes reduces land and social relations to an economic transaction that devalues Indigenous livelihoods and communities. At the same time, empirical studies have shown that Indigenous communities have accepted and even embraced the idea of being paid to conserve land for climate change mitigation. This paper explores this apparent contradiction by investigating the implementation of Programa Socio Bosque (PSB), a PES carbon sequestration programme in Ecuador. Drawing upon primary fieldwork in the highland province of Chimborazo, it makes the case that PES programmes need to be understood as form of state power that reconfigures and reinforces the ways in which Indigenous peoples engage with the state. Particularly important in this regard is the role of the state in reinforcing the agrarian conditions under which Indigenous communities use and interpret PES payments while at the same time reconfiguring new forms of land conservation. Empirically, the research reveals important complementarities between the goals of carbon sequestration PES programmes and Indigenous land-use practices. Methodologically, it highlights the importance of situating the study of PES programmes in a context of land struggles, community–state relations and agrarian change.  相似文献

This paper examines the agroindustrialization process from two supposedly disparate views: development economics and agribusiness research. The evolution of conceptual and methodological approaches emanating from these fields is explored and general observations are made concerning farm economic interdependence, institutional and organizational change, differing scopes of interest, the causes of agroindustrialization, orientation, and the choice of microanalytic tools, terminology, and unit of analysis. Despite an impressive list of hurdles, disincentives, and disconnects, complementarities between the two fields are identified. The paper concludes by exploring the potential of bridging development economics and agribusiness research to inform the future agroindustrialization research agenda.  相似文献

If future demand for maize in Latin America and the Caribbean region (LAC) is to be met from local sources, domestic production must continue to increase. Because further expansion in the area planted to maize is precluded by the limited availability of arable land, future increases in production will have to rely heavily on the spread of productivity‐enhancing hybrid technology. Until now, the diffusion of hybrid maize in LAC has been quite variable. Using data from 18 countries, we investigate factors affecting the hybrid maize diffusion rate. Our findings validate conventional profitability‐based explanations of producer adoption behavior, but they also confirm the importance of supply‐side factors, thereby providing empirical support for the life cycle theory of seed industry development. We conclude that if policy makers in LAC are to accelerate the diffusion of hybrid maize, they will have to ensure an environment in which it is not only profitable for producers to adopt improved germplasm, but also profitable for the seed industry to produce and sell high‐quality seed.  相似文献

This article explores the role of local particularism in relation to the global interest in urban agriculture (UA). A growing movement is advocating UA, but future prospects are limited by variability, unclear expectations, vague responsibilities and leadership in the UA movement. We wonder whether the poor understanding of UA governance is associated with a public discourse and academic literature that too easily adopt the generic and universally claimed benefits. We argue here that uncritical enthusiasm results in an overly instrumental approach to governance of UA with a main focus on stimulating formal (e.g., policy making) and informal advocacy (e.g., civic engagement in UA). We do not deny the importance of formal and informal advocacy in UA development, but rather claim that the potential of UA needs a more nuanced analysis. Study of the interplay between UA advocacy and a city’s contextual characteristics is a worthy pursuit, as it may provide significant and more profound explanations for the divergence observed in UA developments. Case studies performed in Warsaw (Poland) and Ghent (Belgium) serve to illustrate the importance of context. The results suggest that neither case is likely to benefit from a governance strategy that only stimulates greater advocacy and institutional support. The inclusion of city-specific needs, opportunities and pitfalls of UA in the governance strategy can help to move UA toward its full potential. We suggest a policy-making strategy for UA that expands beyond the realm of food production alone. Ultimately, the aim is to steer away from assessing (and critiquing) UA solely against the backdrop of these generic success factors.  相似文献
