This paper documents a significant impact of climate variation on urbanization in sub-Saharan Africa, primarily in arid countries. By lowering farm incomes, reduced moisture availability encourages migration to nearby cities, while wetter conditions slow it. The paper also provides evidence for ruralurban income linkages. In countries with a larger industrial base, reduced moisture shrinks the ...

Farm ponds in Yunlin County first appeared in 1,622 and have played roles in habitation, production, the ecology, culture, and disaster reduction. Farm ponds largely disappeared with the development of urban areas and the industrial sector; thus, effective preservation of the remaining ponds is critical. The criteria to evaluate the preservation value of farm ponds is established by expert ques...

This paper documents a significant impact of climate variation on urbanization in sub-Saharan Africa, primarily in arid countries. By lowering farm incomes, reduced moisture availability encourages migration to nearby cities, while wetter conditions slow it. The paper also provides evidence for ruralurban linkages. In countries where cities are starting to develop an industrial base, reduced mo...

S cientific research has always been a collaborative undertaking, and this is particularly true today. For example, between 1981 and 2001, the average number of coauthors on a paper for the Proceedings of the National Academy of Sciences U S A rose from 3.9 to 8.4 [1]. Why the increase? Biology has always been considered the study of living systems; many of us now think of it as the study of co...

Much remains to be done before agricultural trade is as liberal as world trade in manufactures. But agriculture is distorted by more than agricultural policies. In developing countries especially, farming is discouraged not only by farm protection policies in high-income countries but also by those countries' own manufacturing policies and distortions to services markets. This paper explores th...

Production of improved varieties of cotton for export and local consumption, establishment of ginneries, farm to plant transport services, storage and handling facilities, production of chemicals including natural dyes, industrial starch, caustic soda, hydrochlorides and other finishing chemicals as well as production of textiles. Cotton production has been selected as one of the special Presid...

this article wants to propose this theory that farm corporations are agropolitan development models in iran. as over-concentrating investments to the urban areas did not lead to a trickledown effect to the rural areas. to the extreme, there are ideas to minimize linkages with the urban economy, and to make the rural areas pursue self-sufficiency by maximizing its potentials. however, against th...

In this case study we present our observations of a query processing engine running at a server farm operated by one of our industrial partners. We examine the query engine response time (termed MSBFS) under a variety of conditions. Observations show that there is a persistent residual increase in the server processing time that is only reset with rebooting the hardware.

The socio-economic development of largely subsistence-oriented rural areas is a prominent policy objective in Laos. Whereas in the surrounds of major urban centres and regions with favourable infrastructure and market access a dynamic industrial and service sector have emerged, most of the countryside remains economically undeveloped. Cultivation of commercial tree species is acknowledged as a ...
