In this chapter Iparraguirre D’Elia outlines the productivity performance of Northern Ireland between 995 and 00 . The results indicate that while Northern Ireland returned the highest rate of economic growth of all UK regions between 989 and 00 , its productivity performance has been poor, with most of the economic growth over this period being attributable to increasing employment levels. Nor...

OBJECTIVE To estimate the potential global economic productivity loss associated with the existing burden of visual impairment from uncorrected refractive error (URE). METHODS Conservative assumptions and national population, epidemiological and economic data were used to estimate the purchasing power parity-adjusted gross domestic product (PPP-adjusted GDP) loss for all individuals with impa...

Although the agricultural sector consumes more than 90% of the extracted water, its efficiency is lower than other sectors. Also, according to the population growth and critical role of food security, and the necessity to supply water to other sectors, an increasing pressure to save water, optimized consumption and increasing water use productivity in agriculture will occur in the future. Nowad...

Scientific productivity of middle income countries correlates stronger with present and future wealth than indices reflecting its financial, social, economic or technological sophistication. We identify the contribution of the relative productivity of different scientific disciplines in predicting the future economic growth of a nation. Results show that rich and poor countries differ in the re...

the main purpose of rainfed farming is increasing the water productivity by applying suitable agricultural management including single irrigation (si) and panting time for wheat varieties. in order to study the si optimization and determination its optimal program, a field experiment was conducted as split-split plot based on a randomized complete block design with three replications for differ...

The physiological and agronomic responses of two irrigation systems were compared in ‘Fino 49′ lemon trees (Citrus limon [L.] Burm. fil.). consisted different designs the installation (same amount water frequency): a conventional design (2L, drip lines with six drippers per tree), larger wetted surface (3L, implementing third line nine tree). Results indicated that 3L promoted better distributi...

To assess the total medical costs and productivity losses associated with the 1993 waterborne outbreak of cryptosporidiosis in Milwaukee, Wisconsin, including the average cost per person with mild, moderate, and severe illness, we conducted a retrospective cost-of-illness analysis using data from 11 hospitals in the greater Milwaukee area and epidemiologic data collected during the outbreak. Th...

Increasing crop production per unit volume of water consumption requires recognizing the most dependent variable in drip irrigation to the volume of water consumption and also identifying the most important variables independent of water productivity in surface and subsurface drip irrigation for optimal use of available water resources. The present research was carried out in Behbahan Agricultu...
