kollane on tõenäoliselt keskmine või üle selle
oranz on tõenäoliselt üle keskimise ....

Kus see keskmisest soojem ja kuivem suvi on siis? Vihma, vihma ja veelkord vihma. Uhh, kõik plaanid luhtas!

I've been collecting deintfniois, and this latest one is worth having a look at:From: C. Macaskill (ed), 2013. The Agri Handbook for South Africa, 2013/14. Pretoria, South Africa: Department of Agriculture, Forestry and Fisheries/Rainbow SA Publishingp.325__________... Some notes on sustainabilityA sustainable community ideally does not depend on externalities for its functioning and survival. It would incorporate the following:It is economically viable / has an economic base / has an economic reason for being (raison d'etre). Every location / site / social group has something which makes it unique. Its uniqueness becomes its reason for existence, its magnet for attracting investment / for creating a market. New and existing communities should have some primary activity in its economic make-up. This is important for the creation of a diverse local economy. In urban areas, suburbs should be transformed into an economy which is not dependent on the CBD or commercial/industrial areas for survival. Towns should not depend on cities for their survival.It does not export waste. Limit the waste flow. Keep the biological and technological waste streams separate and upcycle it (where waste is used as resource for the next step in the community's metabolism). This approach follows nature's dictum of waste is food: it eliminates pollution. Create jobs from the waste!It does not import resources. Resources are seen as: material, energy, labour, knowledge, capital and wisdom. Anything local which can be used as catalyst / multiplier for the local economy should be developed, and regarded as a resource.It maintains and fosters diversity. Biological, social and economic. Thedegradation of natural systems is taboo i over-harvesting, loss of biodiversity, monocultures, etc). Diversity is nature's design framework.It grows social capital. Fosters conditions for society to thrive andenhances its capacity to meet its needs:•Level I: Natural systems are not damaged. To do so will undermine and limit that community sooner or later.•Level 2: This relates to conditions at the social system level: a decision made elsewhere might result in people not having access to resources, or to education. Any power that does not recognise interdependence is not sustainable.•Level 3: Successful strategies for social sustainability: participation, transparency, responsibility / accountability, honesty.Local knowledge, wisdom, culture are nurtured, tapped; this is reflected in decisions made at this level. Social and ecological implications are linked.It governs itself. The smaller and more local the government, the more participation there is and the more legitimate, accountable and effective it becomes.It is designed with the intention to facilitate all of the above. Design does not stop at the house, street, landscaping, cadastral subdivisions or planning regulations. It asks questions about what waste is produced, where it goes and how it is managed. It asks questions about how the community is managed and how it earns its keep. It asks questions about how the habitat is enriched by the resident community. In short, the designers (for there are many) must create frameworks which nurture communities and their habitats not to limit or constrain through regulations, for regulation is a signal of design failure.Adapted from Louw van Biljon's Sustainable Development Manifesto (January 2006) in which he acknowledges two crucial books as sources: Cook, David. 2004.
