The purpose of this paper is to investigate the influence of four components of social capital on farmers’ participative behaviour in collective actions for constructing and operating small-scale groundwater irrigation systems on the Guanzhong Plain, Shaanxi Province, China.

The four components (social networks, social trust, social reciprocity and social participation) were derived by employing exploratory factor analysis. Logistic model was used to estimate the influence of these components on farmers’ participative behaviour. Information was obtained from a field survey covering six counties in 2011 of Shaanxi Province, China.

The findings indicate that considering different components of social capital allows for a better understanding of farmers’ participative behaviour. The authors find that higher levels of social trust and social participation lead to a higher propensity for collective action, while social reciprocity reduces the probability of participation. Other socio-economic factors and farming characteristics such as education levels, cultivated area, cropping patterns and grain subsidies also have a significant impact.

The findings suggest creating favourable conditions for communication and information exchanges between households, which enhance their trust of each other, and encourage farmers to participate in collective affairs. Moreover, supportive rules are necessary for the future development of collective action. The results of this study also have implications for national irrigation plans for small-scale irrigation facilities in other developing countries.

A consideration of the different components of social capital allows for a more precise understanding of farmers’ participative behaviour.

The purpose of this paper is to uncover the national intellectual capital (NIC) of South Africa by making comparisons with Poland and Romania.

Based on a database of an NIC measurement model spanning 2001-2015, this study plotted the development trend of the NIC and its component capitals – human, market, process and renewal capitals. Their correlations with GDP per capita (ppp) (GDP hereinafter) were also presented.

The NIC of South Africa is lower than that of both Poland and Romania. Except for the increase of its human capital together with its GDP, the other capitals have lower relevance. Poland experienced highly correlated growth for its NIC and GDP, shedding light for South Africa. The qualitative findings are also reported.

The IMD database carries South African data only for the African continent. Therefore, this paper cannot cover other countries from the continent.

There are three implications from both the quantitative and qualitative analyses: initiate national transformation from the two core issues of education and health; invite and provide attractive incentives for South African returnees from abroad and members of local private sectors to take part in the national transformation efforts; and learn from the NIC development pattern of Poland and Romania by investing in market capital and process capital as soon as possible for faster results.

The research findings of this paper unveil the root of the social problems in South Africa, including education, health, high unemployment and so on. Suggestions are provided for mid-term and long-term potential solutions.

This paper demonstrates the value of an NIC in the economically successful Poland whose growth and GDP growth occurred at a similar pace.
