Reform of tenancy systems and agrarian development: A Latin American case study

The present study employs recent World Bank data to shed light, in a global context, on the transformation of changes in income and inequality into poverty reduction for a large number of countries in sub-Saharan Africa (SSA). The study begins by discussing SSA's progress on poverty. Next, it presents data on how various African countries have fared in terms of the incidence of poverty relative to other countries, with special emphasis on the period since the mid-1990s, when SSA generally experienced a growth resurgence. The paper then decomposes performance on poverty into changes in income and inequality for a sample of SSA countries that have the requisite data. The paper finds that recent progress on poverty has been considerable, in contrast to the earlier, 1980–early 1990s, period. Compared with the progress in a global sample of countries, however, progress has been mixed: nonetheless, although African countries lag behind the Brazil, India, China and Russia group of countries as a whole, many of them have outperformed India. Furthermore, while income growth is found to be the main engine for poverty reduction in SSA in general, the role of inequality is crucial in certain countries. Viewed in a global context, moreover, the low levels of income have inhibited the effectiveness of income and inequality improvements in reducing poverty in many African countries.     

Payments for agrobiodiversity conservation services: An overview of Latin American experiences,lessons learned and upscaling challenges

Many developing countries face a major challenge today: how to safeguard the biodiversity maintained in the fields of the rural poor - which constitute a national and global public good - whilst meeting those same people's development needs and rights? A solution to this dilemma has thus been sought in adapting the design and implementation of Payments for Ecosystem Services (PES) concepts to the conservation of agrobiodiversity.Here we review the application of nine such Payments for Agrobiodiversity Conservation (PACS) schemes that have been applied to date in four Latin American countries over the period 2010–2018. These covered 130 threatened varieties across a number of major food crops, and involved over 100 farming communities and 1,100 farmers (45 % of which were women). Conservation service offers were received through a competitive tender mechanism. Average bid offers revealed high heterogeneity, varying between US$675/ha. to ten times as much.In relation to issues identified as key to PES, such as spatial targeting, differentiated payments and conditionality, the underlying design of the PACS schemes may be considered solid. PACS-related prioritisation processes allow for the a priori identification of sites with high ecosystem service densities and high threat levels. The use of competitive tenders permits accounting for cost heterogeneity in the provision of conservation services and for payments to be differentiated. Conditionality is strong.In terms of implementation, a “back of the envelope” calculation based on the results of the competitive tenders suggests that conservation costs are modest. For a priority conservation portfolio of 100 varieties (which may be from different crops) each with a target area of five hectares, costs would amount to just under US$860,000 over twenty years or US$70,000 p.a. at a 5 % discount rate. The small-scale and one-off nature of the interventions realised to date, along with threatened crop variety seed availability constraints, have however meant that environmental effectiveness has been incomplete in the short-term (area cultivated with specific threatened varieties increased, but still below the “not at risk” threshold). The establishment of systematic monitoring systems is required to determine longer-term impacts and inform more regular PACS interventions within a dynamically evolving systems context.     

Poisoned,Dispossessed and Excluded: A Critique of the Neoliberal Soy Regime in Paraguay

This paper challenges the recent hailing of agricultural biotechnology as a panacea for food insecurity and rural poverty in countries of the global South. Based on an empirical investigation of the neoliberal soy regime in Paraguay, I document how the profound transformation of this country's agricultural mode of production over the past two decades, spurred by the neoliberal restructuring of agriculture and the biorevolution, has jeopardized rural livelihoods. In particular, I demonstrate how the transgenic soyization of Paraguay's agriculture has led to an increased concentration of landholdings, as well as the displacement and disempowerment of peasants and rural labourers who have been rendered surplus to the requirements of agribusiness capital. At the same time, the consolidation of this new agro‐industrial model has fostered a growing dependence on agrochemicals that compromise environmental quality and human health. Thus, I argue, a development policy based on industrial monocropping of genetically modified (GM) soy is inappropriate, unsustainable and unethical.     

土地调整的合理性与必要性：一个研究述评

研究目的:以公平和效率目标为线索探讨土地调整的合理性与必要性,以便更好地推动相关研究和指导土地产权管理制度的建设与完善。研究方法:文献资料法,对比分析法。研究结果:(1)从合理性来看,土地调整体现了村民的集体成员权,并在社会保障、土地利用效率与社会资源配置方面发挥较大作用;(2)从必要性来看,一方面市场补偿机制的缺失导致了调整对农业生产绩效负面影响的产生,另一方面,土地流转作为替代性机制运转受限,土地确权作为政策约束面临着实践困境的同时也忽视了调整的社会、政治功能。研究结论:在现阶段土地调整仍有一定的存在空间,未来要逐步健全调整的替代制度,并加强不同制度之间的衔接和配套建设。     

Women's Land Rights and the Trap of Neo-Conservatism: A Response to Jackson

In response to Cecile Jackson's article, I argue here that Jackson has seriously misrepresented my work, often attributing to me the opposite of what I have said, and turned nuanced and balanced formulations into one-sided extremes. I seek to correct the important misrepresentations, as well as outline my substantive differences with Jackson. In particular, her argument that women should not claim family land for risk of destabilizing family relations could, by extension, have deeply conservative implications for all forms of women's struggles to enhance their freedoms and capabilities. In many South Asian communities, conflict is equally inherent in women choosing their own marriage partners or professions, or seeking gender-equal education, or wanting freedom of reproductive choice or free public interaction. The fear of family conflict could tie women down on numerous such counts as well. Jackson also overextends the resistance to women's claims in family land by treating South Asia as a uniform entity. The analysis in my book on this subject shows a substantial regional variability in kinship structures and social norms, which would make for much less resistance in southern South Asia than in the north, providing promising initial avenues for extending women's land claims. Also, unlike Jackson, I do not locate the process of women acquiring land rights in each woman's isolated struggle within the family, but in a collective struggle that seeks to build support across multiple tiers of society.     

Transfers of landowner willingness to accept: A convergent validity and reliability test using choice experiments in two Canadian watersheds

We examined the reliability and validity of transferring estimates of marginal willingness to accept and compensating surplus. In doing so, we used data from two case studies applying choice experiments to elicit landowner preferences for incentive-based wetland conservation programs in two adjacent watersheds in Southern Ontario, Canada (Grand and Upper Thames Rivers in parallel in 2013). The choice experiment data were modeled in willingness to accept space using a generalized multinomial logit. Transfer reliability was investigated by calculating transfer errors, while validity was investigated by testing the equality of utility functions as well as by assessing the similarity of welfare estimates using traditional hypothesis tests and equivalence tests. The main findings are that transfers of willingness to accept are similar to existing transfers of willingness to pay in terms of validity and reliability. Additionally, a sensitivity analysis finds that including demographic variables in the choice model can lead to lower transfer validity though does not substantially affect reliability. Though further research is required, our results suggest that willingness to accept can be transferred as part of policy analyses.     

Agricultural trade and poverty in Chile: a spatial analysis of product tradability

Many questions have arisen about the relationship between international agricultural trade and poverty in developing countries. This article explores these questions by analyzing local agricultural tradability indices, which measure the degree to which commodities produced in a particular region are traded internationally. Data are examined for Chile, a middle‐income country with a history of international agricultural trade over the last decades. Empirical results indicate that a higher agricultural tradability index is associated with lower poverty rates across Chilean comunas.

Extension services,product quality and yields: the case of grapes in Argentina

This article studies the impact of publicly subsidized agricultural extension services on yields and product quality. We use panel data from grape producers in Mendoza, Argentina to estimate the impacts of farmer trainings. We find a negative overall impact on yields and evidence of a positive average impact on the adoption of higher‐quality grape varieties. By analyzing the dynamic pattern of the estimated effects, we find evidence of a temporary decrease in yields suggesting the existence of an adjustment process following the introduction of higher‐quality grapes. The overall negative effect on yield is driven by a sharp drop in the year of participation. This fades after year one, and two to three years after treatment we observe increases in higher‐quality grape production. Findings reinforce the importance of temporal dimension of extension services.     

Trade and Biotechnology in Latin America: Democratization, Contestation and the Politics of Mobilization

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.     

Poverty and Dependency in Indigenous Rural Livelihoods: Mapuche Experiences in the Andean Foothills of Chile

Rural livelihoods are complex systems of interrelating factors that include human, social, natural, physical and financial capitals. By looking at these capitals in the context of a rural Mapuche community in the Andean foothills, in the local area of Curarrehue (Araucanía Region), it is possible to discern the different challenges being faced and how these can be contextualized in terms of poverty and vulnerability linked to a limited resource base, and also the strong dependent relation with the state and its diverse public policies in the region. Using semi‐structured interviews with the community members, public‐sector officers and academics, and also field observations, this complex local scenario is analysed with a view to understanding the threats that exist for Mapuche livelihoods and the assets that they can mobilize to counter these threats. The paper concludes that physical, natural and financial assets are severely limited and remain the reasons why there is heavy dependency on state resources to maintain these subsistence livelihoods. Traditional knowledge is losing ground against increasingly transcultural influences and practices, while endemic biodiversity is being replaced with monoculture. Consequently, community members (human capital) – in particular, the younger generations – are leaving the community to seek more viable livelihood options, mostly in urban areas. These factors point to the limitations of these local livelihoods based on dependent small‐scale subsistence farming continuing in their current form. This situation poses a serious challenge for Mapuche rural communities and their traditional practices, and also for the Chilean state and the relationship between the two.     

Hegemony,Technological Innovation and Corporate Identities: 50 Years of Agricultural Revolutions in Argentina

The technological changes that have occurred since the mid‐1960s in Argentine agriculture – first the Green Revolution and then the Agribusiness Paradigm – have been conceptualized as revolutionary not only with regard to their productivity improvements but also because they brought with them a change of mentality. Based on two different business conceptions, during each period an agrarian elite led the ‘revolutionary’ process, offering a technological response as the means of guaranteeing agriculture's ‘survival’ after various crises. For each period, we can identify a correspondence between the status given to technology, the conception of business and the type of government regulation. This paper analyses how the proposition of a ‘technological revolution’ corresponds to the construction of the ideological leadership through which the agrarian bourgeoisie managed to orientate agrarian development.     

Interaction between crop insurance and technology adoption decisions: The case of wheat farmers in Chile

This paper examines relationships between crop insurance and input technology decisions among Chilean wheat farmers. Using nationwide farm‐level data, a bivariate probit model is estimated. We investigate the extent to which the adoption of production input technologies is associated with farmers’ participation in the insurance program. We find that relationships between insurance and technology decisions are significant only for family farmers. In particular, there is a negative relationship between participation in the insurance program and the adoption of modern irrigation. Interpretations based on the role of input technologies on insurance adoption and adverse selection behaviours are discussed.     

WTO后时代的新选择:农业支持替代农业保护

The Impact of Migration,Remittances and Public Transfers on Technology Adoption: The Case of Cereal Producers in Rural Kenya

Risk and liquidity constraints are major obstacles to the adoption of modern technologies in many rural African countries. Migration and remittances can help rural households overcome these constraints and increase the adoption of modern technologies. We analyse the impact of migration, remittances and government transfers on the adoption of improved seeds in rural Kenya. Using data from the World Bank, two stage least‐squares estimates show that both migration and remittances positively affect the adoption of improved seeds. However, three stage least‐squares estimates reveal that the adoption of new technologies is more related to migration than remittances.

论流转语境下土地经营权的性质及内涵 ——以物债区分为视角

研究目的：确定土地经营权的权利性质及内涵,并以物债区分为视角对其流转关系进行研究。研究方法：规范分析法。研究结果：《民法典》在用益物权部分引入的土地经营权却呈现诸多债权化的法律特征,其根源在于立法者将其租赁关系一并纳入了物权法的规范视角,导致流转语境下的“土地经营权”并非严格意义上的一种权利类型,而是包含租赁权在内的集合性概念。研究结论：在承认流转语境下土地经营权包含租赁权的前提下,仍应坚持将狭义的土地经营权定性为用益物权,赋予农民专业合作社等入股企业用益物权人的法律地位。同时在法无明文规定时,坚持区分土地经营权的物权式流转和债权式流转,按照“物权优先于债权”的基本法理处理土地经营权之多重流转关系。     

The Interaction of Global Value Chains and Rural Livelihoods: The Case of Smallholder Raspberry Growers in Chile

This paper integrates aspects of global value chain and sustainable rural livelihoods analyses in an exploration of the local impacts of agri‐food globalization in Chile. In particular, it examines the evolution of the raspberry export sector in the context of Chile's non‐traditional agricultural export boom, and considers its importance to smallholder growers and rural households in central Chile. The paper first outlines the geography and structural configuration of the global value chain for Chilean raspberries, and considers modes of governance and forms of coordination between key actors within the chain. Second, the terms and implications of smallholder grower participation in the value chain are explored in a discussion of access to key livelihoods assets. The paper concludes that institutional support to smallholders, even in the case of a crop that is widely seen to have a small‐scale ‘size bias’, remains integral to their capacity to comply with required safety and quality standards and gain and retain market access via the value chain.
