Farmers in the Vietnamese Mekong Delta face a wide range of climate-related and hydrological factors which threaten rice production. Smallholder farmers must adapt to climate change to sustain rice production as their central and most important livelihood activity. A sample was stratified across agro-ecological areas in the Delta affected by flooding, alluvial soils, acid sulphate soils, and saline water intrusion and by derived farmer typologies. A rural livelihoods approach was used in focus group discussions and in-depth interviews to identify and enumerate enabling and constraining adaptation factors. Smallholders experienced diverse natural hazards such as floods, abnormal rains, high temperatures, water scarcity, and salinity intrusion specific to the agro-ecological areas. Adaptation was constrained by labour shortages, water quality, topography, access to combine harvesters, transportation infrastructure, dryers and household savings. Adaptation was enabled by farming techniques and experience, cooperative groups, water quantity, access to information, and ability to purchase agro-chemicals through credit. Small farmers (< 1?ha) were more constrained than large farmers (> 1?ha) who had an expanded livelihood asset base. A range of policy implications are discussed, but adaptation is not just about technological fixes but requires overall improvements in a range of human, social and financial components.  相似文献

This article presents an application of Prezeworski and Teune's so-called “identity-equivalence method” to a large set of indicators of political participation. By relaxing commonly held assumptions about necessary distinctions among types of participation, it is found that the distinction between “conventional” and “unconventional” modes of participation is unnecessary, while the distinction between “government” and “nongovernment” has some merit. The findings also lend further support to the claims of Prezeworski and Teune that the identity-equivalence method is preferable to the identical indicator method.  相似文献

This paper explores the preferences that companies have as they use alternative (quasi) external sources of innovative competencies such as strategic technology alliances, mergers and acquisitions, or a mix of these. These alternatives are studied in the context of distinct industrial, technological and international settings during the first half of the 1990s. Different strategies followed by companies and the role played by routinized sets of preferences are also taken into consideration. The analysis demonstrates that these options are influenced by both different environmental conditions and firm specific circumstances, such as those related to protecting core businesses.  相似文献

This article explores the contradiction between the articulated investment policies, screening criteria or ethical charters of socially responsible investment funds and their actions demonstrated by their portfolio selection practice. The paper provides a background to socially responsible investment and Australia's contribution to greenhouse gas emissions. A discussion of renewable energy options lays the foundation for our main assertion: that this set of possible alternatives provides some new and more environmentally robust options that will better complement the underlying philosophy of funds in the socially responsible investment sector.  相似文献

We investigate whether recent changes in welfare policy affect the migration of low-educated unmarried mothers. Estimates indicate that welfare reform is associated with an increase in employment-related intrastate migration, and a decrease in non-employment related migration, both within and between states. The net effect was a small increase in intrastate migration and a small decrease in interstate migration. The close link between migration and employment suggests that welfare reform has motivated low-income women to move for economic reasons. In general, welfare policy appears to have a much larger effect on residential location because of its relationship to employment than because of benefit differences between states.  相似文献
