Most rural populations in underdeveloped countries are poor, no matter how one defines poverty. The rural poor are neither a homogeneous group, nor is the incidence of poverty equally distributed among them. They do, however, share the underlying causes of their poverty. Landlessness (or absence of productive land) and poor prospects of employment at low wage rates are among the major factors. In some regions, the natural and physical environment exacerbates the conditions of poverty, even if the poor have reasonable entitlements to land. The prospects of improved living conditions for the rural poor depend on many factors. The major ones seem to be (a) population growth, (b) technical progress, (c) markets, and (d) public policy environment. The contribution of each of these factors is not easy to identify, because they act on the human condition in an interdependent and complex way. In most underdeveloped countries, the forces of market and government policies tend to work against the rural poor.

Pseudomonas syringae pv. actinidiae (Psa) causes bacterial canker of kiwifruit, which is an ongoing threat to New Zealand kiwifruit production. Disease control depends on orchard practices such as removal of visibly diseased material, pruning during low-risk periods, and the application of foliar bactericides. Although the use of copper compounds on Actinidia species (kiwifruit) can cause phytotoxicity, copper-based formulations remain a key component of Psa control in New Zealand. The effect of single copper applications on Psa infection of ‘Hort16A’ trap plants was studied over the Spring of 2014 (Sept—Nov). Psa leaf spots were observed at the beginning of October, appearing first on the untreated plants. Although the copper sprays did not achieve complete protection, particularly as the inoculum built up during November, the copper-sprayed plants always had less disease than the untreated plants.

AbstractSince spring 2020, the human world seems to be exceptionally silent due to mobility reduction caused by the COVID-19 pandemic. To better measure the real-time decline of human mobility and changes in socio-economic activities in a timely manner, we constructed a silent index (SI) based on Google’s mobility data. We systematically investigated the relations between SI, new COVID-19 cases, government policy, and the level of economic development. Results showed a drastic impact of the COVID-19 pandemic on increasing SI. The impact of COVID-19 on human mobility varied significantly by country and place. Bi-directional dynamic relationships between SI and the new COVID-19 cases were detected, with a lagging period of one to two weeks. The travel restriction and social policies could immediately affect SI in one week; however, could not effectively sustain in the long run. SI may reflect the disturbing impact of disasters or catastrophic events on the activities related to the global or national economy. Underdeveloped countries are more affected by the COVID-19 pandemic.

Engaging in disaster relief and, more recently, post-disaster reconstruction in developing countries with critical geoeconomic and geopolitical interests has become an increasingly regular and institutionalized component of China’s evolving humanitarian diplomacy over the past decade. Drawn upon novel evidence from China’s growing disaster-related humanitarian assistance to Nepal and unprecedented engagement in Nepal’s long-term post-earthquake rebuild since 2015, this article explores the dynamics behind China’s transforming humanitarian diplomacy. The findings of this article suggest that: 1) geopolitical and geoeconomic interests, represented by the Belt-and-Road Initiative, serve as a critical driver for the development of China’s bilateral partnership with other countries in the disaster sector; 2) long-term cooperation with underdeveloped countries like Nepal provides China, both government and non-state actors (NSAs), with an effective channel to engage with the international humanitarian community and to internalize humanitarian norms; 3) although humanitarian missions remain contingent and instrumental in China’s international relations, they are laying the foundations for a specialized humanitarian policy area with more relevant normative assets, more professional actors, and more sophisticated institutions; 4) NSAs, represented by private foundations and civil NGOs, have played active roles in the state-dominant cooperation in disaster management. This article also suggests that intensified geopolitical confrontations, such as military clashes between India and China along their disputed borders over the past year, would lead to a high degree of politicization of humanitarian missions and partnerships counter-conducive to humanitarian goals.

Many underdeveloped countries have been increasingly demonstrating a strong sentiment of nationalism. This sentiment has found expression in, among other ways, glorification of past traditions and idealization of qualities in the native culture. Such romanticism, if it produces a solidarity and purposeful singlemindedness, can prove expedient for mobilizing social forces necessary to lead to economic change. However, in the process of buttressing national pride and consciousness and in programming for economic development, traditional values and some institutions of the predevelopment phase will be useful only if they are retained in general form. Thus, the Meiji revolution of Japan was successful in romanticizing some of the spirit of old Japan (Bushido) but, at the same time, it adopted the concrete substance of western institutions, which prepared the transformation of the Japanese economy into a developing system. But, if national romanticism is such that it leads to sterile and slavish imitation of anachronistic forms, national energy will be diverted to nativistic frivolity and waste. Such romantic attachment does not lead to the establishment of the social milieu necessary to developing and expanding institutions which will create the conditions for the take-off phase of the economy.
