Purpose: The aim of this article to examine key irrigation management issues and their implications for future research and extension developments.
Design/Methodology/Approach: Peri-urban landscapes are important as they supply fresh fruit, vegetables, turf, ornamental plants and other farm products to the cities. In this study, the Hawkesbury–Nepean Catchment (HNC) was used as a case study and a number of farmers were selected to examine how they use the available technologies for irrigation scheduling to make better decisions for developing water management strategies on their farms. The farmers who participated in the study were mainly growing fruit, turf, vegetables, pasture, olive trees and cut flowers.
Findings: It was observed that a range of factors influenced correct irrigation scheduling decisions of farmers, including their limited understanding of the soil-water-plant relationship, costs of implementing soil-moisture monitoring technology and finding a date for irrigation activity that is compatible with their other farm tasks. It was also found that the farmers’ experiential knowledge played an important role in their irrigation scheduling decisions. The study indicated that irrigation scheduling approaches, which have a low labour requirement and are cost effective and easy to use would be helpful to farmers.
Practical Implications: The study highlighted that there are some irrigation management issues for research and extension that are specific to peri-urban farming and as such they need to be addressed to improve irrigation management and to cope with future water scarcity in urban and peri-urban landscapes.
Originality/Value: This is one of few studies that examine irrigation scheduling issues in a peri-urban context. The study has revealed that irrigation scheduling in reality cannot be an exact science, but it needs to accommodate various farmer constraints in field situations and may have implication for extension activities in peri-urban and other regions. 相似文献
Rapid advances in technology and increased access to technology tools have created new instructional demands and expectations on teachers. Due to the ubiquitous presence of technology in K-12 schools, teachers are being observed on both their pedagogical and technology integration practices. Applying the technological pedagogical and content knowledge (TPCK) framework, the purpose of this study was to determine, through the Delphi research method, a consensus among experts of what should be contained in a classroom observation tool that simultaneously facilitates evaluating pedagogy and technology integration. The study resulted in a list of 30 indicators. 相似文献
The 21 st century classroom requires instructors with more advanced skills and competencies to deliver materials in a way that engages students both traditional and non-traditional. Traditional students have come to expect the incorporation of technology into their classrooms because they have grown up with it and can see its usefulness, while non-traditional students may need additional resources online in order to reinforce new concepts. By employing Web 2.0 technologies, like online video and discussion boards, into both the online and traditional on-campus classrooms, instructors can address both isolation and different learning styles, as well as address issues relating to problems with understanding concepts being taught and respond positively to feedback provided by both the students and administrators. In addition, utilizing Web 2.0 technology in the online classroom can reduce the isolation that many students feel in these classrooms by ensuring students can communicate with other students as well as the instructor. 相似文献
Implementation of digital tools and processes in Higher Education Institutions (HEIs) as an emergent activity depends on the sociomaterial relationships between institutional factors that dynamically interact with each other. This article systematically explores through a literature review some of the most relevant and up-to-date published studies to identify the ‘important factors’ to consider for the implementation of digital tools and processes in HEI. The goal of the paper is to turn these factors, conceived initially as previous conditions or characteristics of the institutions or people, into a list of strategic elements to be fostered by HEI leadership teams to promote better implementation of digital tools and processes in their institutions. In the final part of this work, we propose a framework that reflects these elements in a visual approach that highlights the activity-centred character of the framework as well as the emergent character of the implementation process itself. 相似文献
The paper investigates how technological change in an industry influence which individuals will identify and exploit entrepreneurial opportunities. We propose that the introduction of new development tools will change knowledge-barriers to entry because they enable the abstraction of specialized knowledge that was previously needed for development. Empirically we test the argument using data from the web design industry in a Nordic country during the period 1992–2003. We compare the education and experience of founders before and after the introduction of web administration tools in 1998 and find a significant difference, which supports the main thesis of our argument. 相似文献
