The value of elaeagnus in permaculture (#journal)

Plant genus Elaeagnus: underutilized lycopene and linoleic acid reserve with permaculture potential

Elaeagnus is a genus found wild or as ornamental plants with dense shrub-like structure, fragrant blossoms and silvery foliage. The tiny oblong fruit, with red flesh and pericarp speckled with gold and silvery spots, are edible, with rich antioxidants, phenolic acids and flavonoids. The health benefits of the fruit are blood alcohol removal, pain alleviation, wound healing, cancer prevention, antimicrobial and expectorant etc. Despite this immense food and medicinal potential, the fruit of this genus are languishing in obscurity, and yet to reach mainstream market.

Living with the Land 9) Foraging (video)

Living With The Land | Part 9 | 21st Century Foraging


Wild food experimentalist Fergus Drennan has been foraging for over 25 years. By following the traditions of foraging for wild foods, medicinals and building materials, we can reconnect with our landscapes, learning to live in tune with nature. Fergus brings this tradition into the modern world through his experimental techniques such as making paper from bracket mushrooms and syrups from bullrushes. Fergus shows some common, yet wonderful plants that are not only edible, but are tasty and healthy. Introduced by Bruce Parry, presenter of the BBC series 'Tribe'.

Terraced farming in the Andes (online)

Terrace Farming – an Ancient Indigenous Model for Food Security

8 principles of IPM (#journal)

Eight principles of integrated pest management

There is a need to design cropping systems less dependent on synthetic pesticides. Consequently, the European Union requires the application of eight principles of Integrated Pest Management. Here, we propose to farmers, advisors, and researchers a dynamic and flexible approach that accounts for the diversity of farming situations and the complexities of agroecosystems and that can improve the resilience of cropping systems and our capacity to adapt crop protection to local realities.

Roof top gardens in Italy (#journal)

Techniques and crops for efficient rooftop gardens in Bologna, Italy

Urban rooftop farming favours local food production. Although rooftop farming is perceived as a sustainable system, there is a lack of quantitative studies. Researchers in a community rooftop garden in Bologna, Italy, grew lettuce, tomato, chilli pepper, eggplant, melon and watermelon. Data was analysed by life cycle assessment for environmental and economic performance. Eggplants and tomatoes showed the best environmental performances of about 74 g CO2 per kg. Eggplant production in soil was cheapest at 0.13 € per kg.

Agricultural instensifcation - what does it mean? (#journal)


The blurred boundaries of ecological, sustainable, and agroecological intensification: a review

It is neither clear nor agreed upon what is meant by agricultural  intensification. This article compares the three major uses, ‘ecological intensification’, ‘sustainable intensification’ and ‘agroecological intensification’, by analysing their various definitions, principles and practices.  Confusion is still predominant in the use of these terms, contributing to their use for justifying many different kinds of practices and interventions. Greater precision in defining the terms and the respective practices proposed would indicate more clearly what authors are aiming at with the proposed intensification.

Biodiversity can feed the world (#journal)

Using our agrobiodiversity: plant-based solutions to feed the world

How can we provide an increasing world population with an adequate, reliable and nutritious food supply? This can best be achieved through the utilization of biodiversity and the inclusion of marginal arable lands for agricultural production, while maintaining a broad gene pool to secure the potential for future plant production and supporting rural agricultural communities. The potential for approaches based on the preservation and development of existing agrobiodiversity has not been given sufficient attention in the current scientific and political debates concerning the best strategy to keep pace with global population growth.

Syrian conflict caused by over-grazing (online)

Over-grazing and desertification in the Syrian steppe are the root causes of war

Civil war in Syria is the result of the desertification of the ecologically fragile Syrian steppe - a process that began in 1958 when the former Bedouin commons were opened up to unrestricted grazing. That led to a wider ecological, hydrological and agricultural collapse, and then to a 'rural intifada' of farmers and nomads no longer able to support themselves.

Invasive worms in N. America (online)

Paper on Invasive European Worms 

In response to a question raised during my IPC talk on soil, Dan Halsey has confirmed that European earthworms are indeed invasive and damaging to forest eco-systems in North America. To those of us (Europeans) obsessed with worms as an indicator of good soil health, this comes as quite a shock. You can read Dan's enlightening paper on the subject here. Thanks for the submission Dan.

Species diversity means healthy grassland (online)

 Diversity Breeds Healthy Grassland

A French study looking at the diversity of crop species in grasslands has revealed that genetic diversity breeds healthier, more resilient environments. Researchers from the French state agricultural research institute (INRA) revealed that, not only does a mix of species of crop benefit grassland systems, but different varieties - and so a larger range of genetic diversity - within species also improves health. For optimal production of forage in grasslands it is best to plant several species and a genetically diverse range of each. They reached this conclusion by studying grasslands’ response to drought.

Agro-forestry in Brazil (videos)

Six Films Demonstrating Agro-forestry in Brazil

The Swiss Ernst Götsch is a farmer and researcher who migrated to Brazil in the early 80's and settled on a farm in the cocoa zone of southern Bahia. Since then, he's developed soil recovery techniques through planting methods that mimic the natural regeneration of forests. Götsch developed a set of principles and techniques that enable integrating food production with natural regeneration of forests, which he has termed Sintropic Agriculture. This site shows a series of high quality videos of some of these agro-forestry techniques, subtitled in English.
