Agriculture–nutrition linkages (ANLs) have been increasingly investigated in the literature. However, nutritional returns and costs of household agricultural production practices (APPs) in semisubsistence settings are poorly understood. We fill these knowledge gaps using pooled cross-section data sets in Tajikistan, where semisubsistence farming and undernutrition coexist despite relatively good agricultural infrastructure and education systems. Agricultural diversification, yield enhancement, production expansion are positively associated with various nutritional outcomes, particularly in areas with poor food market access. Decomposition exercises suggest that nutritional returns and costs of these APPs vary across households, and the adoption of APPs is driven by the expected nutritional returns. In Tajikistan, improving nutrition through household ANLs requires growing the smallholder agricultural sector in multiple dimensions, including diversification, intensification, and expansion, while also understanding better the pathways of ANLs and addressing bottlenecks at appropriate stages of such pathways.  相似文献

In this paper we look at the manner in which ideas coming from complexity science change our understanding of the cognitive powers of agents that is really necessary to explain the evolution of markets and of firms. The general ideas behind complex systems dynamics and evolution are presented and then two examples are treated in detail. The first in an evolutionary model of a market in which some new product is developed by competing firms and their “task” is to find a strategy in terms of quality and price that will be sustainable. This essentially requires agents/firms to discover mutually compatible strategies, and to create thereby sustainable market niches. The second example considers the internal structure of firms, in terms of their constituent working practices and skills. It demonstrates that it is precisely their ignorance of the consequences of adopting any particular practice that generates diversity in the emergent capabilities of firms, exploring the dimension of potential demand and therefore leading to a successful and sustainable business sector. The work supports the notion that the cognitive abilities that are involved are not about deduction and logic, as a traditional view of rationality might suggest, but are about the development and contraction of interpretive frameworks, which will be different for each player. The paper links these examples to a general recognition of the idea that complex, multi-agent systems evolve through successive “structural attractors”—multi-dimensional dynamical systems—with temporary structural stability. Because real systems contain both the structure and deviations from it, then there is a constant probing of structural stability and the possibility of qualitative change to a new structural attractor. This resembles the ideas in biological evolution related to “punctuated equilibria,” but it also links this to the idea of emergent and evolving networks of interaction, never of course near thermodynamic equilibrium.   相似文献

The emerging body of knowledge has indicated the positive relationship between spirituality and corporate social responsibility (CSR), yet our understanding of how spirituality can play a role in CSR in general, and in tourism in particular, remains limited. This research takes a qualitative case study approach to the role of spirituality-inspired CSR by providing an empirical investigation of tourism businesses in Bali, Indonesia, where the Hindu based Tri Hita Karana philosophy drives its cultural identity. A total of 20 qualitative interviews and two focus groups were conducted with Bali tourism stakeholders including businesses, government, community and NGOs. The findings show that spirituality plays an important role in CSR in Balinese tourism in three dimensions, namely (1) as a key element of the broader social and cultural context to create a conducive external environment for CSR; (2) as a CSR driver to inspire business leaders; and (3) as a complement to CSR governance, though with limitations. This research contributes to the literature by providing an empirical narrative that demonstrates strong multi-layered links between spirituality and CSR and the implications for tourism destinations in spirituality-oriented cultures.  相似文献

This paper presents a green economy indicator framework for tourism destinations which has been developed in the case study destination of Bali, Indonesia. Whilst the term “green economy” can have many interpretations, here it refers to the global strategy framework surrounding Rio+20, as well as the policies and strategies being developed by tourism destinations as a response. Many uncertainties remain about the effectiveness of these efforts and how they may be measured. For lesser developed countries in particular, reliable data is often difficult to obtain and this study uses a case study approach to identify the relevant, and measurable, indicators in this context. First, a nominal group technique was applied to identify the green economy issues for local tourism stakeholders. The indicators were then selected based on the green economy literature and a review of the available secondary data for the destination. Data on greenhouse gas emissions from tourism was identified as one of the critical gaps and an estimate is provided to show how this could be obtained and monitored. While this indicator framework was developed specifically for Bali, the case study may be relevant for many other island destinations in the lesser developed world that are experiencing rapid tourism growth.  相似文献

This paper reviews the literature on economic development as it relates to indigenous people in the United States and Canada, and focuses on how institutions affect economic development of reservation and reserve economies. Evidence shows that strong property rights to reservation and reserve land and natural resources, whether communal or individual, are and always have been important determinants of productivity. Political and legal institutions that are perceived as stable and predictable to tribal members and to non‐Natives also improve economic opportunities for indigenous people living on reservations and reserves. Research reviewed here also shows that culture and acculturation are important in the development process. Although our emphasis is on North America, the findings are applicable to indigenous people in other parts of the world and shed light on growth questions that loom large for developing countries around the world.  相似文献

Community Supported Agriculture (CSA) programmes have recently received attention for their potential to influence food lifestyle behaviours and health outcomes, though studies have mostly drawn from small samples (n?t-tests assess if paired means are statistically different, and multiple regressions of paired differences on socioeconomic factors, self-reported health, and years of CSA enrolment estimate the effect of respondent characteristics on behaviour change. The results strongly suggest that CSAs have the potential to positively impact shareholders’ food lifestyle behaviours and health outcomes, and that those reporting ‘poor health’ prior to CSA enrolment exhibited the most change overall. These results should be taken as an initial, yet promising, analysis of the impact of CSA participation on shareholder food lifestyle behaviours and health outcomes.  相似文献

There have been repeated calls for a ‘new professionalism’ for carrying out agricultural research for development since the 1990s. At the centre of these calls is a recognition that for agricultural research to support the capacities required to face global patterns of change and their implications on rural livelihoods, requires a more systemic, learning focused and reflexive practice that bridges epistemologies and methodologies. In this paper, we share learning from efforts to mainstream such an approach through a large, multi-partner CGIAR research program working in aquatic agricultural systems. We reflect on four years of implementing research in development (RinD), the program’s approach to the new professionalism. We highlight successes and challenges and describe the key characteristics that define the approach. We conclude it is possible to build a program on a broader approach that embraces multidisciplinarity and engages with stakeholders in social-ecological systems. Our experience also suggests caution is required to ensure there is the time, space and appropriate evaluation methodologies in place to appreciate outcomes different to those to which conventional agricultural research aspires.  相似文献

This paper considers whether the National Economic Association and its journal the Review of Black Political Economy have enhanced the scholarly status of black economists. A bibliometric analysis reveals that while the typical black economist has never published in the Review of Black Political Economy, the share of black economists publishing in the Review of Black Economy approximates the share of all articles published on the economic and political economy of race by black economists, and the share of articles published in the Review of Black Political Economy by black economists appears higher than typical journals in economics—particularly for black economists employed at Historically Black Colleges and Universities. We also find that similar to other economics journals non-black economists dominate the share of published articles, and publications in the Review of Black Political Economy appear to be consistent with Lotka’s Law of scientific productivity suggesting that the journal is a standard outlet for research no different from any other science journal. Our results imply a plausible counterfactual that if the National Economic Association and Review of Black Political Economy did not exist, the scholarly status of blacks in the economics profession would have been lower than currently observed.  相似文献
