Api, se scompaiono loro ci estinguiamo tutti

Posted on

Ci siamo preoccupati moltissimo della scomparsa delle api, e ne siamo ancora molto preoccupati. E’ facile capire l’entità del problema visto che gli alveari degli allevamenti sono costantemente monitorati. Ci stavamo, però quasi per dimenticare degli altri insetti impollinatori: tra cui api, farfalle, vespe, coleotteri etc. Dico quasi perché, il mondo della ricerca non ha mai smesso di preoccuparsene. Recentemente è stato compiuto il primo studio su scala mondiale proprio su questi ultimi. L’Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), il 26 febbraio ha emesso il suo primo report dedicato appunto al declino della biodiversità degli insetti impollinatori. Il titolo del report parla chiaro “il nostro cibo dipende dagli insetti impollinatori che sono sotto minaccia” quindi non solo le api domestiche, ma tutti gli insetti così detti utili. All’Ipbs partecipano 124 membri di governi che collaborano con più di 1000 scienziati di tutto il mondo. In sintesi ecco i risultati: esistono 20.000 specie diverse di insetti impollinatori selvatici, il 90% dei fiori selvatici dipendono da questi insetti, il 75% della produzione alimentare dipende dagli insetti impollinatori (non solo le api domestiche) il cui valore ammonta a 577 miliardi di dollari, di questi insetti il 16% è a rischio di estinzione, il 40% tra api e farfalle selvatiche sono a maggior rischio di estinzione.

A Cohesive Urban Agriculture System

Posted on Updated on

RotterdamUrbanAg_640_425_80

Daylight filters through the filthy glass roof. Dead plants hang forlornly from a steel frame. The drained swimming areas are now just sunken tiled pits, covered in dirt and surrounded by fake rock formations. At this abandoned swimming pool in the center of Rotterdam, two guys are spending a lot of time hanging out in the dank basement and former changing rooms. Tropicana—the former “tropical swim paradise”—closed its doors to the public in 2010. For three years it sat dormant, until August this year. That’s when Mark Slegers and Siemen Cox started using the complex’s windowless spaces to grow pink oyster mushrooms. Co-owners of RotterZwam, the two entrepreneurs go around the city collecting used coffee grounds to make the substrate that feeds the mushrooms, and then sell the fungi locally.

The term “urban agriculture” has received a lot of buzz in the last few years. Balcony tomatoes have become hip; Wellingtons are now a staple of European street fashion. For critics, however, small-scale private initiatives like window boxes and backyard chickens are a good way to encourage popular interest in gardening, not a viable way to feed hungry cities. The fragmented nature of these personal projects often prevents food produced in this way from reaching those truly in need. Such individual efforts need a system.

In Rotterdam, the beginnings of such a system are beginning to take shape. City officials and residents have come together to create one of the most coherent, citywide urban agriculture programs in Europe. The municipal government has made food production a priority, facilitating private initiatives through its generous regulations and open-minded approach to creative strategies. The city believes that urban agriculture offers multiple benefits: local food production encourages social interaction, increases public green space, mitigates the urban heat-island effect and strengthens biodiversity.

EU about Urban And Peri-Urban Agriculture

Posted on Updated on

periurbanagriculture

Urban and peri-urban agriculture has been defined as the cultivation of crops and rearing of animals for food and other uses within and surrounding the boundaries of cities, including fisheries and forestry. It comprehends a multifunctional of food production activities, as well as herbs, medicinal and ornamental plants for both home consumption and for the market. It contributes to fresh food availability of the urban dwellers, as well as to the greening of the cities and the productive reuse of urban waste. In developed countries, urban and peri-urban agriculture is recognized for this provision of local food, as well as recreational, educational and social services. In developing countries, urban and peri-urban agriculture provides income and employment and contributes to local economic development, poverty alleviation and the social inclusion of the urban poor and women. This type of agriculture mostly remains an informal sector that is not well integrated into agricultural policies or urban planning. From the perspective of the European Union policies, we will mention the Common Agricultural Policy (CAP). The CAP 2007-2013 supported several projects on peri-urban agriculture by the LEADER approach (community-led local development method for mobilising and developing rural communities through local public-private partnerships). Regarding the CAP 2014-2020, its measures are applicable to all farmers, including those located in urban and peri-urban areas, who fulfil the eligibility criteria (written question E-002381-14, 12 May 2014).

Mushrooms Are The Next Big Thing In Urban Agriculture

Posted on

The UN forecasts that nearly 70% of the world’s population will live in cities by 2050 so it’s clear we need to grow more food in our cities. No surprise then to see a boom in Urban Agriculture, with projects starting up in cities the world over.

Typically these use methods ranging from traditional raised beds to high tech, expensive aquaponics set ups.

There’s another solution out there and one that is about to take off: growing Oyster mushrooms on used coffee grounds. This method has 3 main advantages:

  1. Quick grow cycle (just 6 weeks!)
  2. High value crop
  3. Can be grown underground or in empty buildings

Why Grow On Coffee Grounds?

Normally, growing Oyster mushrooms requires expensive pastuerisation equipment to sterlise the straw, but growing on coffee is much easier as the brewing process pastuerises the grounds.

And there’s no shortage of grounds! So, by making use of all this waste you can add to a supply of local healthy food.

Picture a world in 5 years from now where there’s a Urban Mushroom Farm in every city. That’s what we at GroCycle are working towards. If you want to find out more sign up for more info about our online course, which opens for enrollment again at the end of this month.

PUBBLIC SPACE TO CREATE LIVING SEED BANKS

Posted on

P1120931-747x560

Though seed banks are valuable, Landlife believes that beauty and liveability lie in releasing their potential, and unlocking public space to create living seed banks, even in the world’s most densely-populated cities, like New York, Hong Kong and Chengdu. As well as fields, spaces in waiting are exciting for their own spontaneous nature, and we can inject a little rhythm with deliberately sown and tended seed for the joy of the evolutionary dance. We sowed several areas in Liverpool with the glorious red poppy, which had evocative connections in different ways, in England for its connection to memories of the first world war, which its poignant centenary. But for many—both the Chinese community and passers by—it was the pure joy of the unremitting red.

Raised Beds: simple solution

Posted on Updated on

Raised beds make tasks like weeding or harvesting simpler. The 3-foot height of the Finkelsteins’ beds lifts the garden to countertop level. But soil fills only the top 10 inches of space. Jeremiah Brophy, who built the beds for the Finkelsteins, explains how they are made:

1. A frame of 2-by-4s, clad in 1-by-12 planks, establishes the size of each bed. (In this case, the beds are 4 feet wide by 16 feet long.) Vertical 2-by-4s and cross braces provide stability at 4-foot intervals down the length of the bed.

2. In most of the Finkelsteins’ beds, empty plastic milk crates stacked 26 inches high support the weight of the soil. In others, sturdy plastic barrels, cut to a height of 26 inches, do the lifting.

3. Atop the barrels or crates is a flat sheet of hardware cloth, a galvanized welded-wire mesh. The hardware cloth is bent upward about 2 inches at the edges and secured to the wooden sides of the beds with fence staples.

4. Heavy-duty, water-permeable landscape fabric rests on the hardware cloth to hold the soil in place. The fabric extends to the top of the frame and is stapled to the wood.
