Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

From "Our Common Future", The Brundtland Commission, 1997

Social justice is a key condition for sustainability!


(1) Authentic food production


"Authenticity will be the buzzword of the 21st century. But what is authentic? Anything that is not devised and

structured to make a profit. Anything that is not controlled by corporations. Anything that exists for its own sake, that

assumes its own shape" (from "Time Line" by Michael Crichton, 2000)

Conventional broiler production

Organic broiler farming


WHO

really cares and pays for quality

FOOD ?


Detection frequency of pesticide residues in strawberries in 2004/2005 (n=36)(source: URL://http://www.lgl.bayern.de)

Conventional foodstuff is regularly contaminated with undesired substances due to the use of chemical-synthetic pesticides.In 2004, more than 35,000 t of pesticides were applied in Germany.

Organic farming renounces completely the use of chemical-synthetic pesticides.


Concept: (1) Authentic food

Aim: fresh local produce (not necessarily produced organically, however, best option is to make organic farming compulsory in EU)

high quality food (primary and secondary compounds)

no anthropogenic contaminants (e.g. pesticides)

transparent management (consumer reliance)

Preserving Baltic food culture

reduction of transport costs

Sustainability gain:

reduced energy consumption

regional identity is strengthened

promotion of rural development

increase in biodiversity


World P resources are limited! ...........50 - 100 years left

only!

(2) Food production in the peak oil, peak phosphorous and climate change era


Agriculture is the largest consumer and non-point emitter

of P


The ecological “footprint“ of P in agriculture ...

... leaves behind hard evidence

The production of each ton of phosphoric acid generates 5 tons of phosphogypsum.

About 60% of the total P load to waterbodies in Germany are non-point losses; contribution of agriculture: 90%.

High P loads cause excessive algae growth resulting in eutrophication.

P fertilization is essential to satisfy the nutrient demand and warrant soil fertility. But excessive P applications enhance the risk of P losses to waterbodies by run-off and erosion.

Mineral P fertilizers add significant amounts of U to soils.

Thermochemical treatment of sewage sludge ashes

BAM/ASH DEC-Procedure (Adam et al. 2009):

Thermochemical treatment at 850 – 1000 °C and addition of Cl-donor increases P-availability in citric acid from 29% in raw ash up to 97.4% in recycled fertilizer product.

Heavy metals are released as volatiles by >95% (Cd, Cu, Pb, Zn), 50-70% (Mo, Sn) and <30% (As, Cr, Ni).


EU regulation No. 1774/2002 permits the co-incineration of carcass meal in coal fired plants. Meat meal of category 2 and 3 can be applied as NP fertilizers.

Category 2 material may contain non-transmittable diseases and residues of medicinal substances.

P in MBM is hardly plant available.

P-recycling: Rendering

AVE 2009

Incineration of MBM destroys pathogens and preserves P (Rosyadi 2003)!


Concept: (2) Food production in the peak oil, peak phosphorous and climate change era

Aim: warranting food security at different scales (regional, national, global scale)


maintenance of high-quality food production under constraints of limited resources and changing environmental conditions by strengthening low input systems such as organic farming close to urban centres and urban agriculture


Help by Organic against Torrents

HOT

(3) Local cross-compliance by expanding organic farming


The HOT model area: catchment of the river Schunter:

Total area: 600 km²

Sealed land: 14%

Agricultural land 362 km² (49% arable, 11% pasture)

Average area flooded actually: 101 km²

Estimated area flooded after complete change to organic farming: 60 km²

As a rule of thumb, organic management of soils

multplies the infiltration rate by factor 2


Concept: (3) Local cross-compliance by expending organic farming

Aim: Reducing negative impacts of conventional farming on infiltration capacity of soils for rainfall


Direct interaction between consumer and producer by providing sealing compensation to organic farmers in

order to reduce impacts of climate change

HOT adds value to agricultural production which is not covered by product prices, but which is highly regarded by the society and thus needs to be rewarded by direct money transfers.

HOT brings organic farms closer to urban centers/markets.

The benefits of HOT are system immanent.


Food or Fuel?

“World hunger is not created by lack of food but by poverty and landlessness,

which deny people access to food. Industrial agriculture actually increases

hunger by raising the cost of farming, by forcing tens of millions of farmers off

the land, and by growing primarily high-profit export and luxury crops"

(Kimbrell, 2002)

20% of Egypt`s population are considered as absolute

poor

44% live beyond the upper poverty line

(4) Closed regional concepts for food and energy production


Concept: (4) Closed regional concepts for food and energy production

Aim: Improving global food security and social justice of availability of resources

Combined food and energy production must not compromise food and energy production locally and globally


Closed energy and nutrient cycles

EcoRegion Partner Conference, Asker (Norway) 24-26 May 2011(5) Education programmes


Concept: (5) Education programmes

Aim: Change of consumer behaviour in terms of deliberate selection of non-processed food, preparation of food and housekeeping

Improving perception of “good food”

Sensibilising for marketing traps: big packs, advantage offers (buy 1, get 1 free)

Improving farming methods: legal separation of industrial animal industry from animal housing on farms; implementation of new technologies (e.g. Precision Agriculture)


Minimising disposal of food

Change of dietary habits (fresh instead of processed food)

Improved health for instance by reduced obesity

Best of Good Practices


Title: F4N - Farmers for Nature

Eco Region good practice: The BSR and other rural areas in Europe are used for agricultural production, recreation and a place to live. Therefore, farmers' involvement in landscape conservation and management is crucial. As the number of farmers has been declining continuously, the risk for loosing nature and landscape conservationists increases. Thus, reorganisation of existing structures and financial rewards are important to protect the regions’ nativeness and originality and to guarantee the future of valuable natural heritage landscapes for locals and tourists.

Trouble-shooting: The inter-sectorial good practice aims at the preservation of nature, landscape and cultural identity of the countryside and brings together farmers, regional organisations and public. All partners elaborated suitable solutions that combines a healthy agrarian management and the EU's Common Agrarian Policy (CAP).

Title: “De-sealing market“

Eco Region good practice: The rural districts Weißeritzkreis and the protected landscape Saxon Switzerland are located in the watershed of rivers and concepts for de-sealing and renaturation measures have been elaborated and tested. It was shown that the compilation of such areas in a “de-sealing market” and subsequent re-use are ideal compensation measures for essential actions such as street building activities without wasting valuable agricultural areas.

Trouble-shooting: The good practice aims at monitoring soil sealing. Registered are inoperable agricultural areas, areas sealed by impermeable covers and abandoned buildings. Concepts for unsealing measure and re-use of these areas are developed.

Title: Precision agriculture to increase the efficiency of farming and promote its environmental compatibility

Eco Region good practice: The quality of agricultural soils can differ considerably even within a small area. These locally varying site properties are additionally influenced by natural features such as hollows, slopes or ridges and cultivation-related impacts such as compaction or erosion. In current agricultural practice these differences in fields are transferred into variable rate operations. Precision agriculture has the potential to significantly increase economic and ecological benefits.

Trouble-shooting: The good practice aims at developing rules, which enable farmers to adjust cultivation techniques to the spatial variation of soil features in the field. Ecologically sensitive areas are addressed with respect to environmentally compatible cultivation techniques. The management guidelines were tested with respect to their agronomical, ecological and economic efficiency on production fields.

Title: Central Tyre Inflation System (CTIS) for tractors

Eco Region good practice: Soil compaction is a major problem on heavy soils and closely related to heavy machinery. Plant growth, soil water regime and gas exchange are affected. An automatic control technology enables the flexible adaptation of the tyre pressure to environmental conditions. The new tyre control technology guarantees driving safety and increases their life span of tyres. On average, the automatic tyre control saves 10 % of fuel. Result is a soil-friendly, energy-efficient and more economical proceeding.

Troubleshooting: The good practice aims at developing a Central Tyre Inflation System, which automatically adapts tyre pressure to changes in soil characteristics on fields and on particular ground.

Title: Sustainable and safe re-use of municipal sewage sludge for nutrient recovery (SUSAN)

Eco Region good practice: P is an essential plant nutrient and cannot be substituted by any other element. Since phosphate rock deposits are a limited non-renewable resource, P-recycling from secondary raw materials is essential to preserve this resource. Municipal sewage sludge contains besides P, but is regularly contaminated with organic and inorganic xenobiotics. Thermo-chemical treatment of sewage sludge is a sustainable way for a safe use of this resource in agriculture rather than dumping it when being incinerated or deposited.

Troubleshooting: This good practice delivered a P-containing thermo-chemically treated sewage sludge ash that is as efficient as conventional P-fertilisers.

Potential of P-recycling of P-containing secondary raw materials from industrial processes, sewage sludge and offals in Germany

The annual P demand of German agriculture is as high as 560,000 t. Full P recovery from sewage sludge, carcass and meat bone meal could satisfy about 13% of the total P demand.
