Article
Full-text available
A tool for calculating the economic and environmental impacts of the use of byproducts of industrial processes that can substitute for perishable resources was presented. This was exemplified by fly ash (the fine fraction of ash originating from coal burned to generate electricity and collected by filtering exhaust gases leaving the furnace), added...

הערכה הערכה כלכלית לכדאיות הטיפול במינים פולשים הוכן ע"י אפרת הדס, אורי נווה, גל זגרון, ציפי סבג פרידקין מינים פולשים שחדרו לישראל עלולים להסב נזק רב לאדם, לסביבה, לתשתיות ולחקלאות. יתרה מכך, המינים פולשים נחשבים לגורם השני בחשיבותו באובדן המגוון הביולוגי, ופוטנציאל הנזק שלהם גבוה. בעבודה שפורסמה בנובמבר 2020 (הדס וחוב') הוצגה הערכה כלכלית לעלות...

Chapter
Anticipating benefits of leaching salts when irrigating with low quality water is problematic due to the complexities of water and salt balances in soil–crop systems and diverse and changing economic realities. We hypothesized that coupling of current physical–biological modeling of soil–crop–salinity interactions with robust economic data would pr...
Article
Interest in desalination to provide irrigation water is on the rise, but there are few tools enabling consideration of feasibility based on both crop responses and economic parameters. We present a biological-physical model for crop response to salinity coupled with economic calculations of farm based costs and benefits to determine profitability o...
Article
Full-text available
The structure and function of the family farm in Israel might become a central theme in discussions on the question of food security in 2050. Therefore, a discussion of the future organizational structure for agricultural production required is an important issue. The purpose of this paper is to present a case study of the long-term historical deve...
Article
Full-text available
The article highlights the benefits of adopting the practice of long-term planning with the aim of helping decision makers and politicians to in-clude scenario thinking in the process of determining food security in Is-rael, 2050. This study addresses the question of food security, a step that is in contrast with agricultural planning consideration...
Data
According to the Water Authority of Israel, Israel's water economy is on the brink of a crisis. Demands are increasing, exceeding the capacity of the natural sources, which are being depleted. Water, as a resource in short supply, necessitated admin-istrative actions in order to attain its efficient utilization, in accordance with the goals set by...
Article
Full-text available
The purpose of this article is to show that a vital and critical element may be missing when discussing project management. This element refers to the reward effect and to the coordination between information flow and organizational processes. The average organizational reward system causes a knowledge worker to reject almost all project management...
Article
Full-text available
The role of agriculture in the Israeli economy has been declining and in the years to come the importance of using land for non-agricultural purposes is going to be vital. The role which agriculture will play depends on careful social cost/effectiveness studies of the alternative uses of land. It will be necessary to forecast land use requirements...
Article

The positive impact of desalinated water on agricultural crops is becoming clearer through different projects and experiments, raising the need to check the feasibility of desalinated water in agriculture. In this work the authors tested the impact of desalinated water in terms of salts on the growth of bananas in the short term, and the economic f...

Treatment of primarily-domestic sewage wastewater involves on-site greenhouse gas (GHG) emissions due to energy inputs, organic matter degradation and biological nutrient removal (BNR). BNR causes both direct emissions and loss of fertilizer value, thus eliminating possible reduction of emissions caused by fertilizer manufacture. In this study, we...

The role of agriculture in the Israeli economy has been declining, and a combination of essential trends has resulted in the emergence of tourism as alternative sources of economic growth in rural areas. These changes have created a new situation, in which tourism-related developments in the rural areas of Israel have become part of the activities...
Article
Full-text available
Sewage effluent for land application is becoming an increasingly important source of irrigation water in many semi-arid regions of the world. Two main approaches to the use of sanitation to upgrade effluent for reuse in agriculture were analyzed: (i) sanitizing to the level required for each crop; or (ii) upgrading all effluent to the sanitary leve...
