The Role of non-timber forest products as safety-nets: A review of evidence with a focus on South Africa

Poor, rural communities are vulnerable to adversity. To secure their livelihoods, people adopt multiple livelihood strategies, including using non-timber forest products (NTFPs). NTFPs have been identified as important to rural livelihoods, as an alternative land-use option as well as in fulfilling an important safety-net function although empirical evidence on the latter’s strength is limited. Whilst NTFPs may contribute towards alleviating poverty, this safety-net function needs more critical and quantitative investigation. This includes the establishment of an applicable definition so this function can be communicated to policy makers and taken into account in national poverty alleviation strategies and, in attempts to promote resource-conserving behaviour by highlighting the value of natural resources (including NTFPs) compared to alternative land-use options. Poverty in rural households is complex and households are vulnerable to a range of shocks. During adversity households can turn to a range of possible safety-nets. What determines the use of NTFPs as a safety-net, how this safety-net function manifests and the strength of this function is poorly understood and there is need for further investigation.     

为“天府之国”农业安全把好第一道关——成都经济区生态地球化学调查主要成果

四川自然环境优越,具有发展现代农业的自然资源、生态环境和劳动力优势。但区域性农业生产环境质量,尤其是土壤的质量与安全性状况不清,使全省现代农业发展缺乏科学支撑。成都经济区生态地球化学调查成果表明,生态地球化学调查可以快速、科学、经济、有效地查明区域农业生态环境质量,为四川规划发展现代农业、调整农业结构布局、提高农产品品质提供科学依据,为四川农业和食品安全把好农业生态环境质量关。     

Gender and urban poverty: Single mothers in Amsterdam

Urban poverty in Western countries is usually defined in terms of social exclusion and integration. Welfare states can be characterized according to three modes of integration, namely market exchange, redistribution and reciprocity. This paper compares the mechanisms of the social integration of unemployed single mothers with those of unemployed men. In two deprived neighbourhoods in Amsterdam, unemployed single mothers and unemployed native-born men were interviewed about their coping strategies with respect to the labour market, social security institutions and social networks. Although the single mothers have serious financial problems, they are better integrated into society at large than the unemployed men are. The single mothers are strongly oriented towards the labour market, successful in getting support from the social security institutions, have strong and supportive social networks, and are integrated into their neighbourhoods. In the conclusion we challenge the idea of vulnerable single mothers and demonstrate the relatively successful integration of this category of women.

水环境质量的综合评价方法研究

讨论了水环境质量的定义，评价了目前水环境质量的评价方法，提出了水环境质量评价应该遵循的原则，建立了水环境质量的评价模型。指出，水环境质量的评价在不能忽略评价水资源量的同时，方法应有所突破；确定了水环境质量的评价应该遵循的全面性原则、独立相关原则、可操作原则、科学性原则、准确性原则等；在选取单项指标的基础上，组合成8个分系统，进而合成对水环境质量相关系数较大的水资源量综合评价指数、水质污染综合评价指数和生态环境综合评价指数，以此作为评价因子建立了水环境质量的综合评价模型。

信息替换的均生函数主分量多步预测

提出随着时间的推移，用新信息取代旧信息的“限定记忆”的时间序列数据处理方法。且仅对均生函数外延矩阵的前Ｌ阶方阵作主分量分析，用数目较少又包含主要信息量的主分量因子对时间序列建模。该方案用于四川省２８个县市的年平均气温的多步预测值与实况值相对误差均在±４％以内，表明该方案用于气温多步预测是有效的。
