Accordingly, a weed mapping was conducted during July 2011, against native （Orobanche ramosa, Cuscuta spp., Sorghum halepense and Xanthium strumarium） and non native （Abutilon theophrasti, Datura stramonium, Solanum elaeagnifolium and Verbesina encelioide） weeds of Lebanon. A global positioning system （Garmin 2006） was used for precise waypoint, elevation, navigation and distance. The result of interviewing and interacting with the residents in 95 villages distributed between the Beq＇aa and the North governorates of Lebanon, along with the observations made on the route, yielded the first detection of Abutilon theophrasti in both governorates. Solanum elaeagnifolium and Verbesina encelioide were not found in the agro-ecosystems of either governorates. This is the first report of the introduction ofAbutilon theophrasti in Lebanon and the establishment of a baseline data on weeds of Lebanon. The adoption of an integrated weed management program with a quarantine and control techniques and methods is needed to manage the spreading of weeds and to lessen their ability to adapt to a constantly changing system which uses several control practices.展开更多

It aimed at the problems in the mining safety management and was put in practice in Lingxin coal mine of Ningxia Coal Industry Group Co., Ltd.. And good effect was obtained in safety work. It developed the mining dynamic safety management based on the building of occupational health and safety management system of mining enterprise and its main contents are as follows： timely identification and dynamic control of accident risk, persistent improvement of safety management performance according to the ＂PDCA＂ circle.展开更多

Employability skills need to be checked rather than unemployment problem in India. The paper further aims to explore the necessary skills to the challenges of globalizing trends. The issues, approaches, and remedial strategies are focused with reference to the people＇s skills. As the reflections of quality and competence depend on transparency and accountability of the organization, it is necessary to improve the required skills which enhance the levels of confidence. The potential employer＇s requirements are need to be worked very keenly by the institutions. The paper also deals with the effective learning process, which is at par with global counter parts. Exposure to the universal student-centered learning is emphasized to enhance the very crucial pace of work place. Finally this paper studies effective micro and macro issues regarding the dynamics of the industry by applying a broad range of employability skills complementing the technical skills.展开更多

How to ensure agricultural ecological security has become a great concern for many scholars. As an important agricultural province in China, Hubei is of great significance to Chinese food security and agricultural sustainable development. This paper aims to establish an index system of agricultural ecological security and security classification of Hubei via Analytic Hierarchy Process and Pressure-State-Response methods. An evaluation of agricultural ecological security in Hubei, with a base of the national average value in 2015, reveals that the security degree has increased by 0.07566 from 0.90150 in 2005 to 0.97716 in 2015. Results show that agricultural ecological security in Hubei has improved but failed to reach the national average and there is still large space for improvement of the security level, considering a trend of deterioration in some indexes, such as per capita water resources, population density, per unit area pesticide load of farmland, forest coverage, grassland degradation rate and average annual precipitation. Influencing factors, especially population spatial distribution, misconduct in agricultural production, insufficient ability in agricultural natural disaster prevention, deficiency of agro-ecological technology of agricultural ecological security in Hubei are analyzed. For improvement of the degree of agricultural ecological security in Hubei, some countermeasures and suggestions are discussed.展开更多

Building on local knowledge and experience these ingenious agricultural systems reflect the evolution of humankind, the diversity of its knowledge and its profound relationship with nature. These systems have resulted not only in outstanding landscapes maintenance and adaptation of globally significant agricultural biodiversity indigenous knowledge systems and resilient ecosystems, but above all, in the sustained provision of multiple goods and services, food and livelihood security and quality of life. However, many of these systems are facing severe threats from various sources including globalization. In 2002 FAO initiated an international partnership initiative： ＂conservation and adaptive management of Globally Important Agricultural Heritage Systems （GIAHS）＂. The global GIAHS initiative aims to establish the basis for the international recognition, dynamic conservation and sustainable management of such systems, agricultural biodiversity and their associated biodiversity knowledge systems, food and livelihood security, landscapes and cultures.展开更多
