Chinese agricultural technology transfer to African typical dry areas: practice and experience

Qiuxia MENG, Jianjie ZHANG, Wenyan XIE, Huaiping ZHOU, Qiang ZHANG

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 4,   Pages 440-454 doi: 10.15302/J-FASE-2020353

Abstract:

Africa has experienced increasing aridity and higher frequency of droughts due to climate change during the half past century with possible adverse effects on agricultural production, especially in dry areas with low rainfall. Under the auspices of the Africa Water Action Program between the Chinese Ministry of Science and Technology (MOST) and the United Nations Environment Program (UNEP), the Institute of Agricultural Environment and Resources, Shanxi Academy of Agricultural Sciences (SAAS-IAER) has worked closely with domestic and overseas partners on technology transfer in Morocco, Zambia, Egypt, Niger and Ethiopia from 2008 to 2013. A drought early warning system has been established and validated, and drought adaptation technologies have been trialed, modified, demonstrated and extended in African countries, and this shows great potential to increase crop production, water and fertilizer use efficiency and desert control in rainfed areas of Africa. The project has continued for six years and is a successful case of technology transfer and capacity building in Africa. The knowledge and experience gained will be useful to researchers, technicians, aid agencies and policy makers who work on agricultural technology transfer for in dry areas of Africa.

Management and Practice of Large-Scale Modern Coal Enterprises

An Wang

Frontiers of Engineering Management 2014, Volume 1, Issue 1,   Pages 13-17 doi: 10.15302/J-FEM-2014004

Abstract: As the coal-dominated energy structure will remain unchanged in the short term, the sustainable development of the coal industry is still serving as one of the foundations for the sound development of the national economy. The construction of modernized mines based on "four orientations", that is, orientations of scale production, modern technology and equipment, informationized management and professional working team, has been rapidly enhancing its development in the recent decade. However, in the next decade or an even longer period, the industry, with the energy centre shifting to the West of China, will be exposed to new options and development in the layout, structure, model, technology, etc.

Circumcision of preschool boys in Baghdad, Iraq: prevalence, current practice and complications

Hussein Naji, Rajaa Mustafa

Frontiers of Medicine 2013, Volume 7, Issue 1,   Pages 122-125 doi: 10.1007/s11684-013-0242-x

Abstract:

Circumcision is probably one of the most ancient surgical operations and has been performed more than any other operation. The aim of this study is to assess the prevalence of circumcision in preschool boys and to present an overview of the current practices and complications in Baghdad, Iraq. A statistical survey was conducted at the Central Teaching Hospital for Children in Baghdad, Iraq during the period April 2003 to October 2004. The survey consisted of structured interviews with the accompanying parents while waiting for their children’s routine appointments. A total of 4000 boys were included. 2 443 (61%) were circumcised and the prevalence of circumcision increased from 18% at 6 months of age to reach 92% at 6 years. Only 180 (7.4%) boys had a medical reason while the rest were circumcised for religious reasons. Parents were the only determinant in deciding the time and place of religious circumcision. Circumcision was performed by a doctor in 732 (30%) boys, by a nurse in 1276 (52%) and by a traditional circumciser in 435 (18%). Post-operative complications were encountered in 209 (8.5%) boys. Circumcision is an important surgical procedure that should be performed by trained medical staff in medical institutions. Circumcision performed by medical professionals caused significantly less complications.
