Abstract

In-field conservation of locally domesticated crop varieties ameliorates agrobiodiversity losses, but the interaction among nationally regulated socioeconomic factors at the local scale tends to discourage this. Analyses of household surveys conducted in Ecuador demonstrate that state and nongovernmental institutions interact to discourage cultivation of locally domesticated varieties of beans (Phaseolus spp.). Land privatization, agricultural extension, and credit programs favor market production of introduced modern bean varieties, and locally domesticated varieties are noted for favorable nutrition, culinary, and agroecological qualities. Resolving disconnections between the market and social values for landrace beans may provide agrobiodiversity conservation opportunities.  相似文献

We used households as the primary unit of analysis to synthesize agrobiodiversity research in small-scale coffee farms and cooperatives of Nicaragua and El Salvador. Surveys, focus groups, and plant inventories were used to analyze agrobiodiversity and its contribution to livelihoods. Households managed high levels of agrobiodiversity, including 100 shade tree and epiphyte species, food crops, and medicinals. Small farms contained higher levels of agrobiodiversity than larger, collectively managed cooperatives. Households benefited from agrobiodiversity through consumption and sales. To better support agrobiodiversity conservation, our analysis calls for a hybrid approach integrating bottom-up initiatives with the resources from top-down projects.  相似文献

The global shift to small- and medium-scale irrigation is potentially compatible with high-agrobiodiversity production. A case study of the Cochabamba region in central Bolivia between 1990 and 2002 is designed to examine new interactions of irrigation with agrobiodiversity through change and continuity of landscape structures and functions. Irrigation change contributed to increased commercial potato and peach farming. Still persistent interactions of canal woodland habitat (landscape matrix including uncultivated or “wild” agrobiodiversity) with patches of cultivated agrobiodiversity helped ensure nutrient transfer and likelihood of gene flow. Farmers' field-level responses continued to include agrobiodiversity, especially multiple farmer varieties (FVs) of Andean maize. Capacities of social–ecological resilience in the period from 1990 to 2002 are estimated to have been moderate in anthropogenic canal woodlands (> 95 percent continued cover, albeit with reduced connectivity) and cultivated agrobiodiversity (viable with local loss of Andean potato FVs) and moderate-high in wild agrobiodiversity (viable with reduced capacity due to modified weed management). Indigenous “ethnodevelopment” applied to Andean community irrigation contributed positively to social–ecological resilience, albeit with significant limitations. Findings recommend that global change policies build emphasis on the interactions of water resource and agrobiodiversity management.  相似文献

Local geography and gender are two major factors determining which crop varieties are cultivated in a case study of two rural villages in Bangladesh. This paper explores the interrelationships between gender, agrobiodiversity, and the use of, and preferences for, improved and local crop varieties. These are examined in relation to rice, minor field crops, and home garden fruits and vegetables. Reasons for both the displacement and the persistence of local varieties (LVs) are analysed in comparison to improved variety (IV) diffusion. The research evaluates agrobiodiversity through the number, types, and varieties of crops grown in fields and home gardens. The desired agroecological, economic, and cultural characteristics of crops grown document how respondents rank their variety preferences. Variety preferences and the perceived importance of LV preservation are compared with what is actually grown. The study indicates that there was little variation between villages in their approach towards the use of IV and LV rice; IVs were cultivated for their high yields and LV rice for taste and culinary uses. However, there were significant differences in relative agricultural dependence between the two villages which led to unique variety preferences. In both villages, women's preferences for IVs or LVs play a major role in crop choices, particularly as they manifest themselves in gendered domains of authority.  相似文献

Seed management has until recently been neglected in agrobiodiversity research. Gender dimensions in seed selection, processing, storage and exchange embody critical task areas in the human management of diverse crop species and varieties. This paper focuses on women's roles in seed management in field and homegarden crops in Bangladesh and reports on the findings of a study in two villages in Tangail District. Seventy-five women were surveyed with a questionnaire and subsets interviewed in-depth; focus groups conducted for women and men provided a means of cross-checking responses. Three distinct areas of agrobiodiversity were addressed: the gendered divisions of labour among agricultural tasks; the pervasiveness of seed saving among respondents; and seed management practices and techniques. The results indicate that while men have greater authority over field activities, homegarden production is the exclusive domain of women. Seed management is seen as an extension of women's domestic duties: women are responsible for all seed processing, storage and exchange for field as well as homegarden crops. The vast majority of seeds sown are saved on-farm by women, revealing important cultural, economic and environmental implications for agrobiodiversity conservation and local differences.  相似文献

To document the diversity of geographic (physical and human) influences on seed exchange, an important component of traditional agricultural systems, household surveys were conducted in four villages in the Mexican Bajío. This research reviews and contributes to an understanding of the purpose, structure, and scale of seed exchange and threats to seed movement. Based on the household survey data, the main factors that distinguish seed exchange at the village level include whether or not the same seed was grown the previous year, what farmers look for in a seed source, and where they have acquired their original seed. When the household survey data are analyzed based on gender, rather than village, different results are obtained. We discuss the diversity of possible influences on the current seed systems in four Bajío communities surveyed and address the possible consequences for agrobiodiversity conservation.  相似文献

Field work to survey and investigate the Anhui Yaoluoping Macrofungi Nature Reserve was undertaken in order to understand and rationally develop macrofungi resources. The results showed that there are, in total, 101 macro-fungal species and varieties, including 59 kinds of edible mushroom, 20 kinds of medicinal mushroom, and 8 kinds of toadstools, grouped according to their economic values. The species belong to 5 classes, 13 orders, 43 families and 67 genera, Another 14 species are unknown fungus food or medicine and remains to be further developed. They are widely distributed in broad-leaved forests, mixed forests, coniferous forests, bamboo forests, wastelands and areas with other vegetation types. Large fungi resources are abundant; some varieties are rare and very valuable to develop. Among those of value are some edible and medicinal mushrooms, anti-cancer sulfur bacteria, morchella, gold equivalent cow bacilli, pine mushrooms, etc. Some species and species resources have still not been fully investigated. These large fungi can be domesticated and cultivated, and have very good commercial development prospects.  相似文献

Abstract

Collaborative conservation has been touted as a viable option for addressing contentious natural resource stewardship issues in a way that represents the diverse voices impacted by, and involved in, conservation decisions. Engaging meaningfully in collaborative conservation involves overcoming a unique set of challenges while also realizing opportunities. In this special issue, we use the term collaborative conservation evaluation to encompass research and evaluation related to collaborative governance and collaborative natural resource management projects, programs, or decision-making processes that leverage a participatory approach, involve multiple stakeholders, and incorporate a range of contemporary evaluation approaches. Here, we provide a series of articles and tools intended to highlight different approaches to evaluation that utilize a variety of methodologies adapted for different contexts. We intend for these articles to spark further conversation and inspire future directions in evaluating collaborative conservation for researchers and practitioners.  相似文献

The aim of this study is to assess the Iberian populations of Forsskaolea tenacissima L. according to its biogeographical interest, habitat, geographical range and conservation status. Results point out that they are restricted to gravel wadis of Tabernas Desert (SE Spain), are scarcely included in protected areas and represent historically isolated populations with relict behaviour. We also describe a new association, Senecioni-Forsskaoleetum tenacissimae. Conservation status of species is cause for concern and two conservation actions must be carried out. Firstly, protected areas should house Forsskaolea populations and secondly, phytosociological characterization of a community allows inventorying its habitat and directing conservation efforts to community level.  相似文献

ABSTRACT. This article examines how peasant farmers build and maintain agrobiodiversity in home gardens found in two traditional peasant communities along the Marañón River in the Peruvian Amazon. Data were gathered through household and garden surveys as well as in‐depth interviews with garden tenders in an upland mixed agricultural village and a lowland fishing village. Substantial variations in cultivated plant diversity were encountered in gardens between and within the villages, which are found to be related to differential exchange of seeds, cuttings, suckers, and other planting material as well as to specific garden and household characteristics. Planting material flows along multiple pathways—from gift giving and purchase to inheritance and scavenging—to the gardens, reflecting a complex and often extensive network of exchange that enables the establishment and maintenance of home garden plant diversity in seemingly isolated and small communities. Further research is needed to identify broader geographical and sociocultural patterns of agrobiodiversity in Amazonia.  相似文献

How researchers describe groups living within or near the world's tropical rain forests has important implications for how and why these groups are targeted for assistance by conservation and development organizations. This article explores how data about market behavior can be used to assess one aspect of forest peoples’ livelihoods: their “dependence” on forest resources as a source of market income. With the intent of revealing the importance of methodology to how we describe forest peoples’ livelihoods, I draw from a multiyear survey of market activity among the Tawahka Sumu of Honduras and distinguish nested measures of the Tawahkas’ engagement in forest‐product sale. Results indicate that whether or not the Tawahka —or any forest group — can be considered financially “dependent” on forest resources depends on the spatial and temporal scales at which data are aggregated. As a group, the Tawahka earned 18 percent of total market income from forest‐product sale, but their group profile masked a high degree of heterogeneity at the village and household level. Similarly, multiyear data indicated that while group‐level generalizations adhere from year to year, they belie considerable change in households’ market behavior across years. I discuss three ways in which the findings are relevant to the theory and practice of conservation and development in the humid tropics. I emphasize the importance of spatial scale in interventions, how market‐oriented conservation schemes can benefit from a broader conceptualization of the economic context in which forest‐product sale occurs, and how longitudinal analysis can reveal the dynamism of forest peoples’ livelihoods.  相似文献

Mexico has a heterogeneous climate due to its geographical location. Half of the Mexican territory is dryland, mostly in the centre and north of the country, within which agriculture is the main activity in the primary production sector. At present, climate variability has a strong impact on Mexican agriculture. This study analysed rainfall variability, its impact on the agricultural productivity in terms of harvested quantity and productivity of 1996‐2014, and in parallel, the role that socioeconomic development plays on the well‐being of the population who live in areas with rainfed agriculture and a semi‐dry climate. The data obtained were analysed with the Statistical Analysis System. A positive correlation was found between rainfall and productivity (r = 0.76 for maize; r = 0.711 for beans). Rainfall variations therefore have a great impact on agricultural productivity, on food security and on the economy. Besides production losses, a parallel consequence is marginalization of the population because producers' income is increasingly reduced due to smaller crop volumes.  相似文献

Development zones in China are planned as self-contained communities in order to achieve a locally balanced distribution of jobs and homes. Yet the plans are often defied by the market, leading to jobs-housing imbalance as an undesired consequence. In this paper, we examine the case of Suzhou Industry Park (SIP) to explore what has actually happened within a Chinese development zone. Our study reveals the de facto qualitative jobs-housing imbalance within SIP notwithstanding the de jure quantitative balance as envisaged in the local land-use plan. This finding explains why most workers within SIP have to search for homes far away from their workplaces. The qualitative imbalance is attributable to a series of interrelated factors, including (a) the oversupply of industrial land vis-à-vis the undersupply of land for public facilities and residential amenities, (b) the unaffordable house price for local workers, and (c) the increased use of automobiles by commuters. On top of its policy implications, this paper also reflects on the fundamental relationship between planning and market as a broader intellectual perspective to study urban China’s mobility, housing and social issues.  相似文献

We investigated the implementation and sustainability of village conservation agreements and village conservation grants facilitated by an integrated conservation and development project (ICDP) around the Kerinci Seblat National Park, Sumatra, Indonesia, 5 years after the project closed. Forty-three percent of agreement actions (n = 180) and 30% of grant activities (n = 74) were sustained. Informants identified numerous factors influencing success, but statistical tests failed to detect simple explanations. Conservation-livelihood agreements have a greater chance of success when preexisting factors are understood and the purpose of the agreement itself is clearly defined.  相似文献

海南芒果业现状、存在问题与对策   总被引:3,自引:0,他引:3  
海南从建臆的1984年开始,实施以琼西南部为重点的芒果产业发展计划。1988年海南建省后,调整热带作物的结构和布局,增加投入,加强科技指导,大力发展早、中熟良种芒果,在短短几年时间内,芒时生产得到了迅速发展。到1998年底全省种植芒果面积达36340hm^2,总产量达58300t,分别比建省前的1987年增加12.6倍和34.5倍。现已成为我国和主要芒果生产基地之一。鉴于我省在短短几年内芒果迅速发展,因此,芒果发展热应适当降温,今后应以优良品种为基础、科技为动力、高产优质高效为目标、改造和提高低产芒果园为中心,完善不同优良品种规范化栽培技术措施,尽快攻破保鲜、贮运、加工难关,走集约化和产业化之路,努力隆低生产成本,增强市场竞争能力,让海南芒果飘香世界,确保芒果业持续稳定发展。  相似文献

The differences in knowledge of biological resource use between societal and demographic groups are often poorly understood; yet they are an important element of sustainability. Differences in gender and generational knowledge of locally useful woody plant species in South African savannas are examined. The results showed that young people and middle-aged females were highly knowledgeable. Over half of the total 267 woody plant species in nine use categories (i.e., medicinal, fruits–seeds, fuelwood, beverage, cultural, furniture, craft, fencing and housing poles) had multiple uses. Therefore, differences in knowledge of resource selection and use between social or demographic groups (for example based on gender and age) may appropriately inform conservation prioritisation, planning and monitoring.  相似文献

Connectivity initiatives typically require conservation action on private lands as a complement to public reserve systems, so they are more likely to succeed if underpinned by knowledge of the social factors influencing landholders' participation. Using a combination of social survey and market research techniques, we identify spatially referenced landholder segments. Using a number of behavioral and attitudinal constructs, including three psychographic constructs not previously used for identifying segments—sense of place, lifestyle motives, and nature values—we identify three lifestyler and two farmer segments, and show that the characteristics of lifestyler segments are more nuanced than previously thought. Preferences for four corridor connectivity initiatives are found to differ across landholder segments, which indicates the importance using a targeted approach for designing connectivity conservation programs. The results highlight the importance for achieving corridor connectivity of the Blue Collar Lifestyler segment, a lower sociodemographic segment not previously identified in the literature.  相似文献

Policy Boosterism,Policy Mobilities,and the Extrospective City   总被引:1,自引:1,他引:0  
Abstract

This study develops the notion of “policy boosterism,” a subset of traditional branding and marketing activities that involves the active promotion of locally developed and/or locally successful policies, programs, or practices across wider geographical fields as well as to broader communities of interested peers. It is argued that policy boosterism is (1) an important element of how urban policy actors engage with global communities of professional peers and with local residents, and (2) a useful concept with which to interrogate and understand how policies and policy knowledge are mobilized among cities. A conceptualization of policy boosterism and its role in global-urban policymaking is developed by combining insights from the burgeoning “policy mobilities” literature with those of the longstanding literature on entrepreneurial city marketing. It is supported by illustrative examples of policy boosterism in Vancouver: the city's Greenest City and Green Capital initiatives, the use of the term “Vancouverism” among the city's urban design community, and demonstrations of new urban technologies during the 2010 Winter Olympics that were used to market a particular vision of the city's governance to people from elsewhere, but also—crucially—to local audiences. The article concludes by highlighting four foci that might frame future work at the intersections of policy boosterism and policy mobilities.  相似文献

While the United Kingdom's emerging brand of Third Way Urban Policy (TWUP) often associates itself with a kind of anarchic vision of self-regulating and self-reproducing local communities, it can in fact be thought of as a thinly veiled moral crusade against vulnerable residents living in deprived neighborhoods. Indeed TWUP might be best conceived as a "flanking support" for the neoliberal turn in urban governance in British cities; morally commendable communities are defined as those who can reattach themselves to the "mainstream" and stand on their own two feet within the terms set by neoliberal market economics. When these morally charged interventions fail to connect locally, they have the potential to stir conflict over who has the authority to judge forms of community life. Mapping and accounting for the uneven development of moral conflicts over community is therefore a pressing concern. To this end, this paper presents a comparative analysis of the different ways in which moral disputes over community have surfaced in two neighborhoods, in particular—the Gorbals in central Glasgow and Ballymun in north Dublin, neighborhoods that have become iconic of the British approach to urban renewal.  相似文献
