I live in the area of Brighton and Hove Council. Their web site has a special councillors search page. Yours might have something similar.
Many districts have a local community group, newsletter and online web site or blog. Were I live there are several local communities online: Prestonville Association, Preston Pages, and the Fiveways Directory.
Practical Action - previously Intermediate Technology - works alongside communities to find practical, solutions to poverty, based upon technology. Technical information and ideas are available online. Visit their site to see their ingenious solutions - clay fridge pots to keep food cool without external power, floating gardens to grow food on flooded land, efficient home-made clay stoves that save fuel and reduce smoke in people's homes and small-scale electricity generators that serve whole villages - and are built and maintained by the villagers themselves, thus increasing their technological independence.
You can buy novel and interesting Practical Presents from here too, such as a floating garden that can survive floods in Bangladesh or donkey plough for families who can't afford to buy an ox.
Shared Interest is a co-operative lending society, investing in fairtrade businesses since 1990 (see also what the Fairtrade Towns co-op has to say about them). Invest your money with them and Shared Interest will be lend it to fairtrade producers and companies, to Mexican coffee co-operative Huatusco for example.
If you would like to invest your money in UK co-operative and social enterprise businesses, you should consider lending to ICOF (Co-operative and Community Finance). I particularly like the fact they help communities buy their local shop or pub to save it closing down; there are now over 200 community-owned village shops supported in this way.
Friends of the Earth and Greenpeace (UK).
The local Green party who's leader Caroline Lucas is MP for Brighton Pavilion since 2010.
The Magpie recycling co-operative, which collects and recycles more things, and more often, than the council do. When they collect your furniture (by arrangement) it is with a view to getting it re-used.
