הדברה-ניקוי כללי ממזיק מסוים- מדבר
19/03/2014 15:35
עדו הרפז
הדברה הינה ניקוי מוחלט ממזיק מסוים- הפיכת הצמח והאזור שלו למדבר..
כלומר מקום בו לא גדל כלום מלבד הצמח אותו אני רוצה לגדל.
זו גישה מאד קיצונית אשר גורמת לשימוש בחומרים מסוכנים לאדם ולסביבה ולעיתים חומרים אשר השאריתיות שלהם- כלומר הזמן בו הם משפיעים על המזיק והסביבה הוא ארוך מאד ולאחר מכן כאשר הם נשטפים אל הקרקע ואל מי התהום הם ממשיכים לפגוע לזמן ארוך בסביבה.
בכדי למנוע - לא להדביר . למנוע ממזיק להגיע אל הצמח או החיה שאני מעונין לגדל אני מציע שיטה מאד פשוטה, אך מעט יקרה ומסורבלת. 
השיטה מוכרת לנו בתור חממה, בית גידול. מבנה סגור בו אני מגדל את הצמחים או בעלי החים שאני רוצה לגדל ובכך אני מונע מבעלי חים וצמחים לא רצויים להגיע אל הגידול שלי.
ניתן לראות היום כיסויי רשת מעל מטעים, בננות , עגבניות פלפלים , תותים ועוד.
נכון להיום כאשר חומרי ההדברה הולכים והופכים לרעילים יותר.(כמו גם התרופות והאנטיביוטיקה שאנו צורכים) ראו החקלאיםפ כי פתרון מניעה פיזית כנגד מזיקים, הוא פתרון יעיל ביותר.
אין נזק לסביבה, אין נזק לפרי, הכיסוי הוא לאורך זמן כך שהעלות ביחס לריסוס היא נמוכה .

Israel’s Center for Urban Agroecology

The B.Z. Mosenson Youth Village

Agroecology is the science and art of growing plants and animals in ways that are consistent with natural ecosystem processes; it is a way of growing plants and animals in harmony with nature. 

Urban agroecology utilizes all available urban areas (rooftops, walls, parks, and even traffic islands), and provides produce of significant and variegated nutritional value in a limited area.  This is all accomplished through a process that conserves resources and that is integrated within the urban environment from  ecological, aesthetic, and social perspectives.  Successful urban agroecology must develop innovative systems that combine advanced agricultural and ecological knowledge with an understanding of the needs and the way of life of the city. 

The Center for Urban Agroecology

The Center for Urban Agroecology is located on the campus of the B.Z. Mosenson Youth Village and utilizes various kinds of spaces throughout the village.   The different agricultural areas offer a wide range of solutions for intensively growing fruit and vegetables in an urban environment.  The Center also utilizes water and waste recycling systems and has its own composting area.  Urban waste treatment and the use of its products in the city’s space is an integral part of urban agroecology, which works toward the creation of sustainable cities. 

Youth for a Sustainable Future

Students at the Mosenson Youth Village are given leadership roles in the Center for Urban Agroecology.  Curently, courses in agroecology are offerred to Mosenson students, but there is much potential to teach other communities, bringing together people from all walks of Israeli society: Jews, Arabs, orthodox, secular, immigrants, senior citizens, youth, etc.  Because  the visiting groups coming to Mosenson to learn agroecology will be drawn from a wide swathe of Israeli society, Jewish as well as Arab, the project also promotes pluralism and diversity, as well as food sustainability.  Training will take place at Mosenson, and upon returning home, participants will receive ongoing guidance and supervision as they set up agroecological hubs.

About the B.Z. Mosenson Youth Village:  The Mosenson Youth Village is one of the oldest and most prestigious educational institutions in Israel. Founded in 1941, the school during its early years was a loving and nurturing home to hundreds of refugees and Holocaust survivors as they sought to rebuild their lives in the Jewish State.  Today, the Mosenson Youth Village proudly continues and embraces this grand tradition of Zionist youth education.  The school's population is a wonderful mix of native Israelis from all over the country and from various socio-economic levels, and also children from new-immigrant families—whether from the former Soviet Union, Ethiopia, Argentina, or other countries.  In addition to agriculture, the current school curriculum emphasizes science and technology (as well as art and sport), and the school remains committed to providing a healthy learning environment where children from very different sectors of Israeli society thrive and flourish as they study, play, and live together in mutual respect.


 

9 Urban Agroecological Hubs on the Campus of the Mosenson Youth Village

1. Greenhouses for vegetables: The size (20 sq. meters) and the shape (domed) of each greenhouse is appropriate for the roof of a private house and is designed to provide a family of 5 with all of its vegetables.  The vegetables grow in containers separated from the ground and benefit from controlled temperature, watering, and fertilizing regimens.  After watering, runoff is gathered in an underground reservoir from which the water is recycled for the gardens of the Village.

2. Vertical farming: This hub features a way of growing leaf-vegetables and spices vertically.  One side of the apparatus is designed to be raised in order to provide increased exposure to the sun and to save on space.   Some of the spices grown in this hub are used for natural and environmentally-friendly pesticides. 

3. An Orchard in containers: In this hub, seven different kinds of trees yield fruit at different times of the year.  The hub approximates what could be grown on the roof of a normal apartment building.  The trees grow in containers of inert soil; the small size of the container limits the growth of the tree, making it easier to work with and allowing for possible re-location.  Runoff water is recycled.

4. Shade garden: The water needs of this hub are supplied through a re-use of the water from the Village’s agriculture.  The shade garden is especially appropriate for hot and dry areas, where it is important to emphasize the creation of pleasant micro-climates (cool, shady areas) and the conservation of water.

5. Hub for the biological treatment of home runoff: The Mosenson Village’s kitchen’s waste water is channeled to this hub for the biological treatment of runoff.  Water treatment if accomplished through an innovative method that is based on plants and microorganisms that grow on the roots of these plants.  The treated water gravitates to the terraced garden (see below).  This hub is itself an attractive hydroponic garden and is situated in the center of the Village. 

6. Terraced garden: This hub contains a terraced, seasonal flower garden separated from the ground by recycled plastic Israel’s Center for Urban Agroecology

6. Terraced garden: This hub contains a terraced, seasonal flower garden separated from the ground by recycled plastic sheeting (which prevents water loss and assures a garden that is protected from ground and water contamination).  The treated kitchen water flows from terrace to terrace by way of gravitation.  The garden also hosts a small landscaped waterfall and pond that use solar energy.

 

7. Produce pyramids: This hub features vertical, pyramid structures that contain a special soil/compost mixture.  The different heights at each level on the sides of the pyramid offer an opportunity to stagger the yield of the produce being grown.  This hub demonstrates great flexibility for urban settings—formerly “dead” spaces as small as 1 square meter can host produce pyramids. 

8. Aquaponics: This hub showcases a food production system that combines conventional aquaculture (raising fish for food or show) with hydroponics (cultivating plants in water) in a symbiotic environment.   In aquaponics, water from an aquaculture system (rich in fish wastes) flows to a hydroponic system where the by-products are broken down by nitrogen-fixing bacteria into nitrates and nitrites, which are utilized by the plants as nutrients. The water is then recirculated back to the aquaculture system.  If the fish in question are not carnivorous, the plants that are grown can serve to feed the fish, fully closing the aquaponics circle.  

In the diagram of aquaponics below, the pipe colored in gray brings the water from the fish to the plants, and the pipe colored in blue brings the purified water from the plants back to the fish. 


 


9. Rooftop farming: This hub sees in the roof of any home great potential for improving the quality of life of the family tending the roof’s garden as well as for the whole urban landscape.  The advantages of rooftop farming are many: 

Improving urban air quality by the absorption of carbon-dioxide and emission of oxygen 

Enhancing the appearance of the urban landscape with attractive roofs, Reducing the phenomenon of “insolation,” whereby solar radiation is absorbed by roads and buildings—and this heat is then stored in area buildings 

Cnserving rainwater 

Decreasing noise pollution

Providing residents with fresh produce.
