The demand structure of resources for new economy is different from the traditional one in that its development may significantly change China’s economic location map and spatial pattern. Based on 343 administrative units of prefecture-level cities in China, this research constructs the measurement index system of terrestrial surface natural resources under the orientation of the new economic demands; this research mainly analyses the spatial distribution characteristics and geographical mechanism of natural resources by means of the spatial autocorrelation and spatial similarity calculation methods. The results show that: (1) The structure and endowment of natural resources under the orientation of the new economic demands need to be reexamined. The significance of a good environment and ecological resources has been highlighted. The coupling of resource elements better reveals the availability of natural resources. (2) The natural resources decrease from southeast to northwest, showing a pattern of “abundant in the south and east and scarce in the north and west”. Natural resources have a significant positive correlation in spatial distribution with two types of agglomeration: high-high agglomeration and low-low agglomeration, showing the local agglomeration feature of “high in the south and low in the north”. (3) Natural factors such as temperature, precipitation and altitude affect the spatial distribution of natural resources, with the temperature being the most significant. This indicates that the original natural environment and its role are the geographical mechanism for the formation and distribution of natural resources. The results could provide a reference for the development and the optimization of China’s new economy.

Purpose of the Study: Egyptian agriculture suffers from many problems related to the use of available economic resources, the most important of which is lack of optimal utilization of resources, wasteful use of agricultural production inputs, reduced efficiency of irrigation water use, and the fertility of agricultural lands are deteriorating, in addition to increasing rates of encroachments on agricultural lands and shifting it from agricultural use to other non-agricultural uses, which limits the agricultural sector ability to achieve high growth rates, especially with the increasing global production of biofuels from crops that individuals consume as food, including wheat and corn, which constitutes an explicit threat to Egyptian food and national security. Objectives: The research aimed to: Estimate the changes in the sources and components of the total productivity of the factors for the main cereal crops in Egypt in the presence and absence of carbon dioxide emissions, Environmental impact assessment of changes in the productivity of these crops. Methods: The study applied analytical approaches to measure changes in productivity, as parameter analysis methods are used as methods of the aggregate production function, and non-parameterized methods of estimation, in addition to (Malmquist, 1953) which is one of the most important indicators of measurement changes in productivity and relies on a Data Envelopment Analysis (DEA) to measure efficiency and changes in TFP productivity and identify the sources of changes in productivity through changes in technical competence and technological change, as the two most important components of the change in total productivity. Results: Wheat Crop: Wheat crop by estimating the change in the different efficiencies of the wheat crop with co2 emissions, it was clear that a decrease in technological change (TC) during the study period, and thus a decrease in the average change in the total factor productivity (TFP), while without co2 emissions effect, the average change in the total factor productivity of (TFPc) indicates an increase in the actual wheat efficiency which is low due to the environmental impact of the emissions. Rice Crop: Rice crop by estimating the change in the different efficiencies of the rice crop with co2 emissions, it became clear that a decrease in the average technological change (TC), thus increasing the average change in the total factor productivity of the (TFP), whereas, without co2 emissions, it was found that the average change in the total factor productivity of the (TFPc) for the study areas was higher. Summer Maize Crop: It was clear that the average technological change (TC) for the summer maize crop with co2 emissions, decreased during the study period, and therefore a decrease in the average change in the total factor productivity of the (TFP), but without co2, an increase in the annual average of the change in technical efficiency (TEC), and a decrease in the average technological change (TC), i.e. in the use of technology, and an increase in the average change in the total factor productivity (TFPc).

In the present study, an attempt has been made to analyze the growth on the basis of secondary data in area, production and productivity of major crops in Jammu region for the period from 1984-85 to 2013-14. The comparison has been made over the time to examine the trends and it was observed that in Jammu region rice, maize and wheat crop dominated the area and these crops together occupied more than 84 per cent of gross cropped area during the last three decades. The entire period 1984-85 to 2013-14 found that rice, maize, wheat, millets, condiments and spices, fruits and vegetables, fodder crops had positive area growth while pulses, barley, jawar, bajra, sugarcane, oilseeds and fibers had negative area growth. The production was positive for rice, wheat and pulses and negative for maize whereas as yield was recorded positive for rice, wheat and pulses and negative for maize crop. The study concluded that most of the cultivated land is dominated by cereals groups, therefore, need for crop diversification which ultimately leads to protection of soil health, regular returns, employment opportunities as well as better and balanced diet for the local people in the region.

Abstract Background The local social and physical environment influences health outcomes and individual behaviour. It remains unknown if the environmental influence is independent of individual socioeconomic status (SES). We studied the spatial distribution of mammography screening uptake in the Swiss urban population of Geneva and determined its independence from SES. Methods We used individual-level geo-referenced data (n = 5 002) from the participants in the Bus Santé study, a population-based cross-sectional study ongoing in Geneva since 1992. Data from 1992 to 2014 have been included in this study. Local indicators of spatial association (LISA) were calculated and used to assess the spatial dependence of mammography uptake (defined as having had a mammography in the past). We report unadjusted spatial clusters; adjusted for neighbourhood income and individual educational attainment; and for demographic variables (age and Swiss nationality). Furthermore, we evaluated the association between the distance to the nearest screening centre and the identified spatial clusters. Results Mammography uptake was not randomly distributed, with spatial clusters overlapping with those of SES. Spatial clusters were reduced to 56.2% of their initial size (n = 1,033) after adjustment for SES variables. Adjustment for age and nationality further reduced the proportion of individuals exhibiting spatially-dependent behaviour (to 36.5% of the initial size). Distance to the nearest screening centre was not associated with the spatial distribution of mammography uptake. Conclusions High definition spatial distribution studies using analysis of individual data allow identifying spatial clusters which are not based on pre-determined administrative units (e.g. postal code) but rather on individual behaviour. Persistent spatial clusters after adjustment for SES and demographic confounders suggest additional area-level determinants influencing the spatial distribution of mammography uptake. Key messages High definition spatial studies can help uncover new patterns of health outcomes distribution independent of SES and based on individual behaviour, rather than administrative units. While SES explains a great proportion of the spatial distribution of mammography uptake, other still elusive factors may be contributing to the observed spatial inequalities in mammography uptake.

With the construction of Grand Canal Culture Belt being upgraded to a national strategy, the authors used GIS and other analytical techniques to give an overview of 2,834 recreational resource points distributed in 49 prefecture-level administrative units of eight provinces or cities along the Grand Canal Culture Belt, analyzed the features of their quantitative and spatial distribution, finding that: (i) the recreational resources along the Grand Canal are spatially related to the major river systems, lakes and arteries of communication; (ii) the recreational resources along the Grand Canal are generally distinguished by a spatial agglomeration of “two poles and two sub-centers”, in which the natural recreational resources are distributed in the pattern of “three points and one line” while the cultural recreational resources are distributed with a notable feature of polarization. On that basis, the authors proposed several suggestions about the utilization of recreational resources along the Grand Canal Culture Belt: (i) Establishing a system of diversified recreational products by adapting to local conditions; (ii) building national scenic byways along the Grand Canal by relying on major river systems and arteries of communication; (iii) giving priority to the development of four recreational sections of the Grand Canal and foster core growth poles.

Abstract A field evaluation of the technical performance of centre pivot sprinkler irrigation system was carried out during the maize crop growing season and when operating with different working speeds: S1 - 40%, S2 - 60% and S3 - 80%. For this goal, four uniformity measurements are to be considered in the evaluation; coefficient of uniformity (CU), distribution uniformity (DU), potential efficiency of low quarter application (PELQ) and actual efficiency of low quarter application (AELQ). The first step of evaluation of the sprinkler irrigation system is to compare the measured uniformity values with the standard values, DU ≥ 75%, CU ≥ 85%, AELQ and PELQ ≥ 90%. Effect of variation of speed produced CU values of 80.3, 82.7 and 86% for S1, S2, and S3 speed, respectively. Furthermore, DU standard value was obtained at S3 speed of 82%. Moreover, AELQ and PELQ were below the acceptable standard level of 90% for all speeds. Non-uniform water application leads to over or under irrigation in various parts of the field which can result in wasted water and energy. Therefore, regular evaluation of the irrigation equipments is needed to efficiently and effectively manage irrigation.

SUMMARYExperiments made over a period of 2 years (1975–6) covering three crop seasons at Pantnagar, India, on the comparative utility of intercropping the principal maize crop with legumes in economizing fertilizer N requirements of the former, indicated that among soya bean, cowpea, pigeonpea and groundnut, soya bean was the most suitable. At 40 kg N/ha intercropping maize with soya bean gave 19·5% more yield than taking it as a pure crop. When the option to use adequate fertilizer N does not exist, as is invariably the case with the average Indian farmer, intercropping maize with legumes, such as soya bean, is the logical way out. All the intercropping treatments left sufficient residual fertility to significantly increase yield of a wheat crop given no fertilizer which followed maize.
