Hydroponic Growing in Chile

Santiago’s surrounding landscape is shaped by several stand-alone hills with the mountains of the Andes chain visible from most points in the city.

Santiago’s surrounding landscape is shaped by several stand-alone hills with the mountains of the Andes chain visible from most points in the city.

In Latin American countries like Chile, there is an increasing interest in learning about hydroponics and the solutions it can offer to agriculture in the region.

Hydroponics first came to Latin America during the 1970s. At the outset, it was used to market vegetables considered luxury items. By the mid-1980s, hydroponic farming began to be a popular alternative among the very poorest, who adopted the practice in the hillside slums surrounding most large Latin American cities. See More

Innovations in Agriculture

After a 14-hour flight from Sydney, the Qantas Airbus 380 landed soon after midnight in Dubai.  Progress through the airport was rapid, and I was soon on a taxi heading for Abu Dhabi, the site for the ‘The Global Forum for Innovations in Agriculture (GFIA)’ meeting organised at the instigation of the Cooperation Council for the Arab States of the Gulf (GCC).

Jakarta … towards food security

Jakarta_02In Jakarta, Indonesia, urban farming and hydroponics are initiatives that are increasingly being utilised to feed the city’s expanding population and ensure food security. PH&G looks at hydroponic strawberry production in Bandung, and also talks to one of the country’s largest hydroponic growers, which not only supplies supermarkets across Jakarta, but also runs an educational facility to train hydroponic professionals of the future.

Varroa Mite

The 1.5mm-long parasite, Varroa destructor, is the apex pest of honey bees worldwide, hindering the beneficial insects' ability to pollinate a range of fruit, vegetable, flower and nut crops (Image courtesy of the US Dept. Of Agriculture, Agriculture Research Service)

Varroa is a genus of parasitic mites associated with honeybees. This pinhead-size pest attacks developing bee larvae and adult bees, resulting in deformed bees, reduced lifespan and ultimately, the destruction of the colony or hive. MIKE NICHOLS reports on the New Zealand experience and the impact of Varroa mites on honeybee populations, the honey industry and crop pollination. He highlights the potential of using domesticated bumblebees for pollinating horticultural crops. See More

COIR: Sustainable Growing Media

Coir dust after sieving.

Coir is a natural fibre extracted from the husk of coconut and used in a wide range of  domestic products including floor mats, door mats, brushes and mattress filling. However, in recent years, there has been an increasing interest in the use of this renewable resource as a  horticulture growing medium.

Urban Aquaponics

In backyards, business spaces and community centres across Sydney, hobbyists and professional growers alike are increasingly turning to aquaponics as an alternative, relatively low-cost method for producing food in an urban environment.

AQUAPONICS: Myth or Magic?

Typical aquaponic floating raft bed system.

Typical aquaponic floating raft bed system.

There is considerable interest worldwide in the ‘sustainability’ that aquaponics (the growing of fish and a horticultural crop in the same system), appears to offer in terms of food production, but the actual science behind aquaponics is extremely limited. Much of this interest appears to be emotive, rather than factual, and the purpose of this article is to attempt to clarify where aquaponics can be scientifically proven.
