Mechanisation of large‐scale agricultural fields often requires the application of modern technologies such as mechanical power, automation, control and robotics. These technologies are generally associated with relatively well developed economies. The application of these technologies in some developing countries in Africa and Asia is limited by factors such as technology compatibility with the environment, availability of resources to facilitate the technology adoption, cost of technology purchase, government policies, adequacy of technology and appropriateness in addressing the needs of the population. As a result, many of the available resources have been used inadequately by farmers, who continue to rely mostly on conventional means of agricultural production, using traditional tools and equipment in most cases. This has led to low productivity and high cost of production among others. Therefore this paper attempts to evaluate the application of present day technology and its limitations to the advancement of large‐scale mechanisation in developing countries of Africa and Asia. Particular emphasis is given to a general understanding of the various levels of mechanisation, present day technology, its management and application to large‐scale agricultural fields. This review also focuses on/gives emphasis to future outlook that will enable a gradual, evolutionary and sustainable technological change. The study concludes that large‐scale‐agricultural farm mechanisation for sustainable food production in Africa and Asia must be anchored on a coherent strategy based on the actual needs and priorities of the large‐scale farmers. © 2016 Society of Chemical Industry 相似文献

Malnutrition continues to be a major public health challenge especially in South Asian developing countries. The aim of the present review is to spotlight the magnitude of the prevalence of malnutrition and its dynamics in South Asian region and to suggest potential approaches for the prevention and control of this issue of public health significance. An extensive review of literature, covering malnutrition and its determinants, health and economic consequences and pragmatic preventive strategies was performed on computer based bibliographic databases (PubMed, Google Scholar, Scopus, Medline and Sciencedirect.com) to retrieve abstracts and full texts for India, Pakistan, Bangladesh, Sri Lanka and Nepal. All relevant titles and abstracts were examined and evaluated for malnutrition and its prevalence in South Asia. The results revealed malnutrition to be a major public health problem and a potential cause of high disease burden and mortality in South Asia. Compelling evidence suggests malnutrition to be the leading cause of stunting, wasting and underweight with drastic economic consequences among vulnerable populations. Reduced cognitive performance and low productivity have also been associated with micronutrients malnutrition. Suboptimal breastfeeding, inadequate food supply, micronutrient deficiencies, low household income, poor health care system, increased healthcare costs, illiteracy, unhygienic and substandard living, inappropriate child's care and the caregiver, food insecurity and on top of that vicious cycle of poverty, have been recognized as principal indicators for growing malnutrition prevalence in South Asia. Global organizations, local governments, program managers, NGOs, academia, industry in particular and the society at large need to take up the challenge to completely confiscate malnutrition from the region for economic prosperity and a healthier future. 相似文献

The power sector has been going through quite turbulent times during the past couple of years. During this time, several long-held tenets of the sector have been rewritten. As new technologies appear and as the surge of renewables dramatically transforms the system, we witness an emergence of new market players and possibilities. With key issues revolving around different problem areas, the importance of taking a multidisciplinary view on forming development strategies proves crucial in achieving desired outcomes. Having a detailed understanding of the dynamics underpinning energy markets is crucial for both decision-makers and investors. Forming a successful development strategy or a policy framework requires reconciling a string of technical, environmental, economic and social factors. Choosing the right combination of policies and technologies could fuel economic growth while still providing secure and affordable energy in line with low-carbon goals. In this light, we take Southeast Europe (SEE) as a practical example and study various questions regarding legal frameworks and development policies of countries in the region. The methodology structure allows considering environmental, economic, technology and policy issues. Each country's electricity sector is evaluated using a comprehensive database, with particular consideration to its affordability, self-reliance and sustainability. This study presents an overview to help clarify some of the aspects behind forming a successful framework capable of making the right decisions for the future. 相似文献

This paper presents the results of our corroborated study of grassroots Internet sites and authors in the nation of Kyrgyzstan, exceptional in Central Asia for its deregulated Internet policy. The study presents a set of semistructured interviews with notable grassroots Internet authors and activists, including bloggers, forum participants, and journalists, and analyzes this data via a critical communication and media studies lens to point to significant implications on emergent social, cultural, and political movements in the nation. 相似文献

Response of seasonal vegetation development to climatic variations in eastern central Asia 总被引:9,自引:0,他引:9
Meteorological records show that central Asia has experienced one of the strongest warming signals in the world over the last 30 years. The objective of this study was to examine the seasonal vegetation response to the recent climatic variation on the Mongolian steppes, the third largest grassland in the world. The onset date of green-up for central Asia was estimated using time-series analysis of advanced very high resolution radiometer (AVHRR) normalized difference vegetation index (NDVI) biweekly composite data collected between January 1982 and December 1991. Monthly precipitation and mean temperature data (1982-1990) were acquired from 19 meteorological stations throughout the grasslands of the eastern Mongolian steppes in China. Our results showed that while the taiga forest north of the Mongolian steppes (>50°N) experienced an earlier onset of green-up during the study period, a later onset was observed at the eastern and northern edges of the Gobi Desert (40°N-50°N). Responses of different vegetation types to climatic variability appeared to vary with vegetation characteristics and spring soil moisture availability of specific sites. Plant stress caused by drought was the most significant contributor to later vegetation green-up as observed from satellite imagery over the desert steppe. Areas with greater seasonal soil moisture greened up earlier in the growing season. Our results suggested that water budget limitations determine the pattern of vegetation responses to atmospheric warming. 相似文献
