Restoring degraded soil structure (journal)

Patterns and Factors of Soil Structure Recovery as Revealed From a Tillage and Cover-Crop Experiment in a Compacted Orchard

Degraded soil structure recovery is much less documented than structure degradation and compaction. In this field experiment, the effects of rotary spade tillage followed by Sorghum cover crop on the degraded structure of the soil from an orchard were evaluated. A large and significant improvement of the structure quality scores were obtained. Analysis revealed a significant impact of the tillage and root development on the structure recovery, larger than the effect of SOC content. This structural change pattern was similar to those reported from other studies. Though the observed final structure quality of the top layer was good, its vulnerability remains large due to its small SOC to clay ratio.

Permaculture and soil organic matter (journal)

Effects of Permaculture Practices on Soil Physicochemical Properties and Organic Matter Distribution in Aggregates: A Case Study of the Bec-Hellouin Farm (France)

Authors studied the impact of permaculture and biointensive micro-gardening practices on soil physicochemical properties and soil organic matter (SOM) distribution. The physicochemical properties of soils in permaculture implemented for 7 years were compared with a soil under pasture and a soil under conventional agriculture. Permaculture/ biointensive micro-gardening practices enhanced SOM storage and modified the distribution of SOM, while substantially improving nutrient bioavailability and strongly affecting soil properties. The effects of permaculture practices on soil properties would certainly vary depending on geopedoclimatic context, justifying the need to implement the approach for other soil types.

Assessing crop/livestock/forestry systems (#journal)

Crop, livestock and forestry performance assessment under different production systems in the north of Mato Grosso, Brazil

Integrated crop–livestock–forestry systems are a priority theme in the public policy of the Brazilian government. Lack of technical and scientific knowledge may be contributing to the low adoption of these complex systems. Ten production systems were evaluated from 2011 to 2015, including crop production (soybean/corn), livestock (palisade grass pastures with Nellore steers) and forestry (Eucalyptus urograndis H13), in both single and integrated systems. A negative influence on the grain yields in the fourth and fifth years for soybean and the third year onward for maize was observe. Forage availability and animal weight gain were increased by the rotation of crop–livestock, while no differences were found for wood volume yield.

Eating organic lowers risk of cancer (online)

Eating organic food lowers risk of certain cancers, study suggests

Eating organic food could cut the risk of cancer, a new study has found. Non-Hodgkin’s lymphoma and breast cancer rates were lower among those who more frequently eschewed conventional food, according to researchers from the Centre of Research in Epidemiology and Statistics in Paris who examined data from nearly 70,000 adults. The reduced risk may be because those who eat organic are not exposed to the chemical pesticides and medicines which are generally used to treat regular fruit, veg, meat and fish, they suggested.

Carbon negative district heating (online)

Tampere’s Hiedanranta to be the first in Finland to produce carbon-negative district heating

The commercial production of carbon-negative district heating has begun for first time in Finland. The Carbofex factory heats up wood and turns it into a mineral, i.e. biochar. This happens through pyrolysis. When the biochar is used as a soil amendment it will sequester carbon permanently in the soil. The production process also produces waste heat. That heat will be bought by Tampereen Sähkölaitos Oy, which will distribute it to its own customers via its district heating network, heating thirty high rise blocks.

Biochar included in IPCC report (online)

Biochar and PyCCS included as negative emission technology by the IPCC

Biochar was included for the first time as a promising negative emission technology in the new IPCC special report, 8th October 2018. The inclusion of biochar is an important milestone for mitigating climate change and fostering research on pyrogenic carbon. Since the EU is obliged to fund research in negative emission technologies due to the Paris Agreement, it can be expected that biochar research and development will start to receive more funding in the near term. Here, authors provide a short summary on pyrogenic carbon capture and storage (PyCCS) and relevant excerpts from the new IPCC special report. 

Agroecology in Canada


 Agroecology in Canada: Towards an Integration of Agroecological Practice, Movement, and Science
This article surveys the current state of agroecology in Canada, giving particular attention to agroecological practices, the related social movements, and the achievements of agroecological science. In each of these realms, we find that agroecology emerges as a response to the various social and ecological problems associated with the prevailing industrial model of agricultural production that has long been promoted in the country under settler colonialism.

Agroforestry boosts ecosystem services (#journal)


Modelling tree density effects on provisioning ecosystem services in Europe
One constraint on the uptake of agroforestry is a lack of knowledge on how specific agroforestry designs affect productivity. A biophysical model called Yield-SAFE, was used: (1) to quantify the food, material and biomass energy production of four case study systems, and (2) to quantify how tree density determined the supply of ecosystem services. The modelled results showed that including trees in pasture or arable systems increased the accumulated energy of the system in comparison with monoculture. The greatest accumulated energy occurred in the highest tree density agroforestry system at all the case study sites. This suggests that the capture of environmental resources, such as light and water, for obtaining provisioning services is most effective in high density agroforestry systems.

Intercropping effects on maize (thesis)


I (Chris WB) found this MSc thesis completely by chance while looking for something else. Although neither permacultural nor organic, it provides a great methodology for studying the effects on yield and insect contol of different intercropping systems. I am posting it here mainly because of the methodology and the literature review which may be useful to others, but if you want a snapshot of the results, the study found maize grows best when intercropped with cluster bean or field bean, both of which have substantial economic benefits. Most of the inter crops clearly reduced insect damage compared to maize alone, with maize/field bean and maize/cluster bean creating the lowest population of insect pests.

Polyculture doubles CO2 sequestration (online)

Species-rich forests store twice as much carbon as monocultures

Species-rich subtropical forests can take up, on average, twice as much carbon as monocultures. An international research team with the involvement of the University of Zurich has evaluated data from forests grown specifically for this purpose in China with a total of over 150,000 trees. After eight years, such species-rich forest plots stored an average of 32 tons of carbon per hectare in above ground biomass. By contrast, monocultures averaged only 12 tons of carbon per hectare—less than half as much.

Kevin Anderson's radical response to IPCC (online)

Professor Kevin Anderson responds to the IPCC report
The UK's foremost radical expert gives his response, and his challenge: 'The responsibility for global emissions is heavily skewed towards the lifestyles of a relatively few high emitters. Almost 50% of global carbon emissions arise from the activities of around 10% of the global population, increasing to 70% of emissions from just 20% of citizens. Impose a limit on the per-capita carbon footprint of the top 10% of global emitters, equivalent to that of an average European citizen, and global emissions could be reduced by one third in a year or two.'

Agroforestry greens The Sahel (Journal)

Hydraulic Redistribution by Native Sahelian Shrubs: Bioirrigation to Resist In-Season Drought

Hydraulic redistribution (HR) by woody vegetation has been proposed as a potential water source for crops in intercropped systems. The native woody shrub, Guiera senegalensis, grows across the African Sahel and has shown profound yield benefits to associated pearl millet crops, especially in drought years. The authors tested whether this benefit resulted from the shrubs performing hydraulic redistribution (HR). They found millet biomass production when intercropped with shrubs was over 900% greater than crops grown without shrubs. This finding illuminates HR and water transfer as an important mechanism in agroforestry in a region where food security is a serious issue.

Evidence for permaculture principles (journal)


Permaculture—Scientific Evidence of Principles for the Agroecological Design of Farming Systems

Permaculture practitioners have long been using design principles without them ever being scrutinized. Here, the authors review the scientific literature to evaluate the scientific basis for the design principles proposed by permaculture co-originator, David Holmgren. Scientific evidence for all twelve principles is presented. Even though permaculture principles describing the structure of favorable agroecosystems were quite similar to the agroecological approach, permaculture in addition provides principles to guide the design, implementation, and maintenance of resilient agroecological systems.

Agroforesty is climate resilient (online)

 Planting water – Agroforestry research at Ernst Götsch in Bahia

The agroforestry movement is growing fast under the Brazilian sun. In all corners of the country, people are now turning bare lands into bountiful food forests. All of them inspired by one man who, 40 years ago, set out to plant a system that would take agroforestry to a higher stratum. His name is Ernst Gotsch. New research at his cocoa farm suggests that agroforestry creates greater climate resilience in forests.

How fast the carbon clock is ticking (online)

How fast the carbon clock is ticking

"In the Paris Agreement, all countries worldwide decided to limit global warming to well below 2°C (ideally as much as 1.5°C) compared to pre-industrial levels. This is extremely ambitious and essentially means that we are tightening our carbon budget. In concrete terms, it means that reaching the 2°C target with a medium probability would allow us to emit at maximum only about 720 gigatonnes (Gt) of CO2 between 2018 and 2100 into the atmosphere (stand 1.1.2018).¹ However, at present the world is still emitting 40 Gt of carbon dioxide.⁴ This equals 1,268 metric tonnes per second."

Mercator Research Institute on Global Commons and Climate Change have produced an online, interactive carbon clock. It allows you to explore different policy options and how much time different scientific thought would allow.

Permaculture national curriculum in Timor-Leste (online)


Permaculture/Agroecology system in Timor-Leste National School Curriculum for Basic Education


In 2013, the Ministry of Education of Timor-Leste decided to reform its national curriculum for Basic Education. Permaculture school gardens had been part of the discipline of Arts and Culture. The organization behind this movement is Permatil (Permaculture Timor-Leste), established in 2002. This school garden program now became part of formal education. 1415 schools have introduced school gardens, to help  students learn how to grow seasonal food crops that can contribute to the school feeding program, shifting from passive learning inside classrooms into activities outside the classroom, and providing beauty to the school landscaping. Students and communities learn how to copy the model into their home garden to improve health and nutrition of the wider family.

Permaculture in resilience research (journal)


Designing for resilience: permaculture as a transdisciplinary methodology in applied resilience research
This paper examines the relationship between resilience research and permaculture. Applying permaculture as a tool in research design can enable research to contribute more directly, immediately, and effectively to building community resilience. The author considers three case studies that involve permaculture as both research topic and methodology. Each provides evidence that research activities contribute to community resilience, and that this can be attributed to the application of permaculture principles and methods in research design. In particular, permaculture embeds iterative processes of action learning to enhance adaptive capacity within communities. The author suggests that this may be an instance of a general situation whereby research both incorporates and enhances existing learning processes that contribute to community resilience.

Local knowledge in permaculture design (online)


Permaculture Design: Linking Local Knowledge in Land Use Planning for House Compound

This study attempts to understand the knowledge of local people in planning and designing a permaculture system. In particular, this study identifies land use planning for permaculture zones, and design elements in permaculture zones. The results discussed that local people, regardless of their locations either urban or rural, tend to take into account the natural layout, interior architecture and internal activities in planning and designing the zones for their house compound. The zoning is not only beneficial for efficient energy use, but also sustainable both in environmental, social and economic aspects appropriate to the livelihood and culture of local people. Therefore, local knowledge should be considered when designing a permaculture system.

Permaculture's effect on soil carbon and fertility (online)

Permaculture practices effect on soil fertility and organic matter distribution in aggregate-size classes
In identical geopedoclimatic conditions, the authors compared Soil Organic Matter (SOM) allocation and soil fertility in a pasture under permaculture with a soil under conventional agriculture. Permaculture practices increased bioavailable nutrients Ca, Mg, K and P, total nitrogen concentrations and organic carbon stocks, which was explained by the very large manure inputs. Permaculture practices had little effect on soil aggregation. Permaculture practices may enhance soil fertility and SOM storage, but further research is needed. In addition, a carbon balance should be performed to determine if the additional OC storage corresponds to a net sink of CO2.

The real cost of cheap food (book)

The Real Cost of Cheap Food
This book critically examines the dominant food regime, by seriously asking whether we can afford cheap food and exploring what exactly cheap food affords us. The author argues that the social and environmental costs of cheap food will be paid for by future generations and examines international development, national security, health care, industrial meat production, organic farming, corporate responsibility, government subsidies, food aid and global commodity markets. The book concludes by suggesting ways forward, going beyond the usual solutions such as farmers markets, community supported agriculture, and community gardens.

Big potential for urban farming


 Big data suggests big potential for urban farming
This new study estimates that urban agriculture could produce 180 million tonnes of food each year. Urban agriculture could also provide other benefits worth $160 billion each year, globally, including energy savings through insulation of rooftops, reducing the urban heat-island effect by increasing vegetation cover, avoiding stormwater runoff, fixing nitrogen and controlling pests.

Only a paradigm shift will stop climate change (online)

Liberal philanthropy is dooming the planet to climate disaster

The Hewlett Foundation's philanthropic initiative to address climate change is set to fail, according to a strategy document setting out the initiative’s five-year plan, and committing $600 million to address climate change. While the Hewlett strategy document is certainly not all bad, its avoidance of specific solutions like regenerative agro-ecology, radical de-fossilization of the economy and biochar is bizarre. Its core approach appears to be based on an inexplicable ignorance and obfuscation of some of the most relevant scientific findings. Real solutions are available, but they do not sit easily within the existing paradigm. They point to a radical paradigm shift, a new type of civilisation, and a new type of human for a truly sustainable and prosperous world.

We're all subsidising environmental destruction (online)

Two stumbling blocks on the road to regeneration: externalities and subsidies

 The prevailing opinion among today’s political and economic elites is that economic globalisation is in some sense inevitable. Rather than being inevitable, economic globalisation is, in fact, the result of a number of carefully chosen policies. Paradoxically many of these directly contradict the basic tenets of classical free market economic theory, from which the proponents of economic globalisation draw inspiration and authority. By understanding the key reasons why the global economy behaves as it does today, we will be in a better position to discern the core patterns underlying economic behaviour and to change them. Two key drivers of today’s global economy are externalities and subsidies.

Microgreen/mushroom permaculture (journal)

Expanding Herbal Microgreen-Mushroom Permaculture Can Be an Efficient Way toRecycle Agricultural Waste While Treating and Feeding the World

A sustainable cycle of substrate utilization is beginning to manifest with plant waste being used as mushroom substrate, and spent (used) mushroom substrate being used in place of traditional soil, for herbal microgreen growth. This approach to efficiency and conservation an example of permaculture, or the development of agricultural ecosystems intended to be sustainable and self-sufficient.

The urgency of climate action (online)

Three Things We Don’t Understand About Climate Change

Thinking about climate change is not something that comes natural to humans — or ‘consumers’ as we have been called for decades. It is not only emotionally unpleasant, but analytically extremely challenging. Most of us do not grasp how immediate this situation has become, how fast it is progressing and what the scale of change needed is. After individuals, nations and corporations understand the urgency and the rate, they should be honest about the scale of action needed in order to avoid collapse of the biosphere and thus civilisation.

UK farmers who meet the sustainability challenge (report)

New report with aim to investigate how the science of agroecology can play a central role in the way our green and pleasant land is managed in the future.

A new report commissioned by the Land Use Policy Group and funded by Scottish Natural Heritage has taken a unique approach to help UK farmers meet the sustainability challenge by using the experiences of farmers that have ‘redesigned’ their farming systems utilising natural resources, such as clover grass leys in the crop rotation, to secure a healthier future for the environment and their businesses.

The aim was to investigate how the science of agroecology can play a central role in the way our green and pleasant land is managed in the future.

Analysing the practical experiences of a group of farmers from Scotland, England and Wales the report aims to unravel farmer expectations, risks and opportunities to help form future policy in the UK based on agroecological farming practices.

The group of fourteen farmers involved in the study were quite diverse and wide ranging – from small scale to large commercial enterprises with on-farm approaches covering agroforestry, pasture-fed livestock systems, organic and integrated farming with direct drilling and/or integration of livestock in arable operations.

The report has recommendations for further action to support agroecology, including the need to develop a support programme to facilitate the transition towards more sustainable farming systems.

Key questions for restoring degraded ecosystems (journal)



One hundred priority questions for landscape restoration in Europe


Free open access until 3rd May 2018

Scientists and researchers outline the key questions that we need to answer to ensure restoration of marine and terrestrial landscapes in Europe is as effective as possible.

Ecological restoration is the process of assisting or allowing the recovery of an ecosystem that has been degraded, damaged, or destroyed.  It is an increasingly important element in strategies aimed at reducing biodiversity loss and reversing declines. It is especially relevant in the intensively managed, farmed, urbanised and industrialised landscapes common in Europe.

The questions are usefully divided into eight sections:

  • conservation of biodiversity; 
  • connectivity, migration and translocations; 
  • delivering and evaluating restoration; 
  • natural processes; 
  • ecosystem services; 
  • social and cultural aspects of restoration; 
  • policy and governance; and economics


The growing research effort investigating larger-scale ecological processes and connectivity (such as the needs of migratory species, the impacts of climate change on species' ranges, and the need to restore ecosystem function) is increasingly focusing attention on large or landscape-scale conservation and restoration. The questions presented in this paper highlight areas where this research could usefully be focused, in order to ensure that restoration projects are carried out in the most appropriate locations, using the best methods and effectively including all stakeholders, in order to maximise their success.

Regen ag for profit and biodiversity (journal)

Regenerative agriculture: merging farming and natural resource conservation profitably

Most cropland in the United States is characterized by large monocultures, whose productivity is maintained through a strong reliance on costly tillage, external fertilizers, and pesticides. Despite this, farmers have developed a regenerative model of farm production that promotes soil health and biodiversity, while producing nutrient-dense farm products profitably. When evaluated, regenerative farming systems provided greater ecosystem services and profitability. Pests were 10-fold more abundant in insecticide-treated corn fields, and although regenerative fields had 29% lower grain production they had 78% higher profits over traditional corn production systems.

Species richness linked to a healthy diet (journal)

Dietary species richness as a measure of food biodiversity and nutritional quality of diets

Biodiversity is key for human and environmental health. Available dietary and ecological indicators are not designed to assess the intricate relationship between food biodiversity and diet quality. The authors applied biodiversity indicators to dietary intake data and assessed associations with diet quality of women and young children. Data from 24-hour diet recalls of 6,226 participants (34% women) in rural areas from seven low- and middle-income countries were analyzed. A total of 234 different species were consumed, of which <30% were consumed in more than one country. Compared with Simpson’s index of diversity and functional diversity, species richness (SR) showed stronger associations and better diagnostic properties with micronutrient adequacy. For every additional species consumed, dietary nutrient adequacy increased by 0.03 (P < 0.001). Dietary SR is recommended as the most appropriate measure of food biodiversity in diets.

Why we must keep carbon unburned (online)


We need to stay below 1.5 Degrees: Un-burnable Carbon overtakes Peak Oil

While the peak oil conversation has been very important in the first decade of the 21st Century, climate change has now almost eclipsed this issue. Now that there is increasing scientific certainty that to be safe humanity would be wise to keep global warming below 1.5 degrees Celsius, the issue is less whether and when we will run out of fossil fuels and much more how we will manage to agree on a global carbon budget and declare almost 80% of the remaining fossil fuel reserves as unburnable. While the potential fossil fuel reserves left might be twice as much as the current listed reserves, the carbon budget we have to stick to in order to have 50% chance to stay under 1.5 ºC of global average warming is less than a fifth of current fossil fuel reserves.

Coke CEO promises a world without waste (online)


Why a World Without Waste is Possible

Every hour, an estimated 900 metric tons of plastic waste entered our oceans. That’s the mass of nearly 600 mid-size sedans. That’s unacceptable. It’s also unsustainable. If left unchecked, plastic waste will slowly choke our oceans and waterways. That’s why Coca-Cola have announced a bold, ambitious goal: to help collect and recycle a bottle or can for every one we sell by 2030. Regardless of where it comes from, we want every package to have more than one life. This is our vision for a World Without Waste.

Climate and tech: biggest global risks (online)

Climate and tech pose the biggest risks to our world in 2018

We live in an era of unprecedented technological, scientific and financial resources. I remain optimistic about the future, yet the risks to our world are increasing not reducing. They are systemic in nature and require a collective will to address them. Unfortunately, this is happening at exactly the time that nationalism, protectionism and populism are rising, and rules-based multilateralism is declining. I fear we may squander the opportunity to move towards a more sustainable, equitable and inclusive future. We must act together and we must act now.

GMO food labelling laws in the USA (online)

The Laws of Labels: What You Need to Know about GMO
Many people are concerned about GMOs and tend to select food products with labels that are non-GMO certified in an effort to make healthier choices. If you are a food manufacturer or plan to sell your home-grown products to a mass market, you should be aware of the laws of labeling foods GMO or non-GMO in your country or state. If you work to produce certified organic food products, your products are already non-GMO. This is a result of certifications that require manufacturers to abstain from using any genetically modified ingredients. Manufacturers producing organic food can therefore use non-GMO labeling, such as:
· GMO free
· Made with non-GMO ingredients
· Always non-GMO
· Non-GMO certified
If you have a food business or are a manufacturer in the USA, there are other GMO labeling laws you should know to ensure that your products are marketed and sold to customers with correct, true information.
