Abstract: Drawing on Harold Brookfield's seminal interventions on intensification and disintensification in tropical agriculture, the paper argues that a de‐linking of poverty and livelihoods in rural areas from farming and agricultural resources is occurring in rural South‐East Asia. This is often driven as much by changes in lifestyles and life views than by economic and environmental imperatives. The paper proposes that farming is in the process of losing its resonance and significance for the rural poor. Emerging patterns of change in the South‐East Asian countryside are used to construct a generalised framework of agrarian transition where the current trend towards pluriactivity is likely to be replaced by a mixed landscape of agrarian entrepreneurs, neopeasants and remnant smallholders. The paper concludes by reflecting on the implications of this trajectory for understanding poverty and pro‐poor interventions in the countryside.  相似文献

Abstract: It is increasingly recognised that both formal and informal institutions could be important variables in explaining the diversity of capitalist systems. However, less is known about the relative importance of regional institutions for regional economic activity and regional development, especially in developing countries. This article analyses the relative importance of regional institutions to regional capitalist systems in Southeast Asia, using the comparative institutional approach of ‘business systems’. Two comparisons are made that enable an analysis of the relative importance of regional institutions: one between two regional economies in the same country (Cebu and Negros Oriental in the Philippines) and one between two bordering regional economies in different countries (Satun in Thailand and Perlis in Malaysia). We investigate four sets of economic institutions: the extent of alliance coordination of supply and demand, the extent of collaboration between competitors, the extent of alliance coordination of sectors and access to finance. The results suggest that regional economic institutions are stronger in agricultural areas with relatively weak national economic institutions and that the presence of strong and enabling regional economic institutions is one of the factors that lead to taking advantage of favourable agricultural conditions, to economic growth and, ultimately, to catching up.  相似文献

磷肥对紫花苜蓿生产力影响的研究概述   总被引:1,自引:0,他引:1  
随着畜牧业的发展,对苜蓿的种植生产提出了更高的要求。磷肥的有效利用是影响苜蓿生产力的关键因素之一。笔者系统概述了苜蓿缺磷的主要症状,不同地区施磷量和方法对苜蓿生产力的影响,施磷提升苜蓿生产力的途径,苜蓿的磷素吸收机制以及磷素与其他养分及水分互作对苜蓿生产的影响。建议今后针对不同地区的土壤理化性质,特别是有效磷含量,测土施肥,综合不同地区的结果建立气候-土壤-施肥模型,并进一步开展磷素促进苜蓿生长的生理和分子机制的研究,以期为苜蓿研究和产业发展提供有益信息。  相似文献
