Join Frankfurt's water-saving pledge, one habit at a time

Join Frankfurt's water-saving pledge, one habit at a time The city's "Frankfurt spart Wasser!" campaign, now running its fourth-plus warm season, asks residents to treat drinking water as the precious resource it is as heat and drought periods stretch longer. Posters, tram wraps, and postcards carry pledges like "Ich dreh ab", "Ich spar's mir", and "Ich fang dich auf": turn it off, skip it, catch it. What you can do - Shower instead of bathing: five minutes under the shower uses roughly a third of a full bath (about 50 versus 150 litres), and a water-saving showerhead or flow restrictor cuts it further - Turn off the tap while brushing your teeth or lathering up: saving hot water saves energy too - Run washing machines and dishwashers only when full, on eco programmes, and look for water-efficient models when buying new - Water the garden or balcony pots in the morning or evening, collect rainwater in a barrel, and choose drought-tolerant plants How it works The city renews the campaign each warm season with posters on Litfaßsäulen, tram and digital ads, U-Bahn messaging, and postcards stocked at neighbourhood libraries, restaurants, and cafés. It is part of Frankfurt's municipal water concept for securing long-term supply, and even children get a turn, with a button-making station at the GrünGürtel-Tier's birthday festival. Why it matters Longer heat and dry spells are lowering groundwater levels in and around Frankfurt. None of these habits cost much, but multiplied across a city they ease pressure on a resource everyone assumes will keep flowing from the tap.

Hofflohmärkte, neighbourhood courtyard flea market in Munich

Hofflohmärkte, neighbourhood courtyard flea market in Munich Hofflohmärkte is a Germany-wide reuse programme: residents register a private courtyard, garden, or garage and sell pre-loved goods while neighbours follow a linked tour plan through the district in Munich. The platform runs in 30+ cities and 300+ neighbourhoods; initiator René Götz operates registration, participants organise their own courtyards. What you can do - Download the tour plan PDF for your Viertel (published about one week before each market day) - Walk the linked addresses and buy second-hand treasures from neighbours - Register your own Hof if you have landlord approval and goods to pass on How it works - Sales stay on private ground only, not sidewalks or public space - Typical hours: Saturdays 10–16, Sundays 11–16 (Munich also runs selected Friday evenings with M-net sponsorship) - No food sales; private sellers only, professional dealers are not welcome - Registration closes three weeks before each date for tour-plan marking; late sign-ups are accepted but may not appear on the map - Organisers may cancel a date if fewer than 30 courtyards register, fees are then refunded About Hofflohmärkte Neighbours register a private Hof, Garten, or Garage on Hofflohmärkte and sell used goods on scheduled Viertel days. Registered addresses appear on a tour plan published about one week before each date. Sales happen on private ground only. See city pages for local schedules and Spielregeln & Tipps for seller rules. Why it matters Every item re-homed from a courtyard is one less thing bought new or landfilled, and a chance to meet the people who live behind the front doors.

Grow clean-cookstove markets with women's last-mile groups

Grow clean-cookstove markets with women's last-mile groups Energising Development (EnDev) helps Kenya build lively markets for improved cookstoves and small solar (with GIZ, SNV, and CLASP). Households buy from producers, traders, and last-mile entrepreneurs, including women's groups and savings groups that demonstrate and sell stoves village by village. There is no single GIZ volunteer desk; the builder move is growing that market where you already cook and trade. What you can do - Buy or recommend an improved cookstove from a local seller or women's group near you, then share how it cooks in your kitchen - Join or start a savings group (chama) that sells or finances stoves on instalments for neighbours - If you produce or distribute ICS, study the climate-friendly cooking Kenya and Senegal professionalisation pattern and partner pathways on EnDev Kenya - Host a short cooking demo with your women's group, school, or market stall so new customers can taste the difference How it works EnDev strengthens producers and last-mile agents so quality stoves reach rural customers through ordinary commerce. Savings groups often make instalments workable. Use the country page to find the approach; then act through local sellers and groups already on the ground. Why it matters Cleaner cookstoves free hours, clear kitchen air, and keep more trees standing when neighbours sell and buy them together.

Join Wikimania 2027 in Santiago

Join Wikimania 2027 in Santiago Wikimania 2027 will gather editors in Santiago while hosts finalise hybrid venue plans. Neighbour tip Bring a friend who has never visited before; shared first visits help you remember names, routes, and follow-up events you might skip alone. What you can do in Santiago - Ask a volunteer what follow-up dates they recommend for newcomers before you leave the site - Read movement updates on the 2027:Wikimania wiki and Diff posts (Wikimania 2027 wiki) - Watch for scholarship and registration windows when the host team publishes them - Prepare session ideas on Latin American language communities, climate data, and decolonial archives - Join local Wikimedia Chile meet-ups listed on the wiki before the main conference week How to join Registration opens on wikimania.wikimedia.org when the host committee announces pricing and hybrid access rules. Do not book non-refundable travel until the venue is confirmed on official channels. Share one thing you learned with a neighbour when you return home; teaching doubles your own recall and spreads open routines. When & where Santiago, Chile - venue TBA per the organiser page per Wikimedia Foundation notes on Diff and the wiki. Hybrid participation details will follow venue confirmation. Why it matters in Santiago A Global South Wikimania centres editors who keep Spanish, Mapudungun, and regional knowledge online against platform churn and misinformation. Bring a notebook; details you capture on site help your block organise a return visit or small solidarity fund drive. Good to know - Is the event hybrid? Movement communications describe hybrid plans; confirm streaming rules when registration opens. - When will the venue be announced? Follow wikimania.wikimedia.org; Solarpunker skips a map marker until the address is public. - Are scholarships available? Wikimania usually offers scholarships; deadlines appear on the wiki each cycle.

Walk historic energy and transport networks

Walk historic energy and transport networks The 2026 motto NetzWERKE: Denkmale & Infrastruktur puts bridges, locks, power houses, rail sheds, and supply buildings in the spotlight. These places once moved people, water, goods, and power. On Open Monument Day they open so you can see how earlier networks still shape streets and rivers. What you can do - Search the programme for industry, Technik, or infrastructure tags near you - Visit a dated listing such as Dresden's Bahnbetriebswerk Dresden-Altstadt when it opens - Ask guides how the site fed a town: water, power, freight, or passenger rail - Carry the pattern into advocacy: keep repairable infrastructure visible in your own city How it works DSD invites owners to present monuments as network nodes, not only as pretty facades. Filter for technical monuments, then pick one deep listing with hours and access notes. Why it matters Energy and transport heritage make climate and mobility conversations tangible. You stand inside the systems that still underwrite daily life.

Corporate Sustainability Handprint at GIZ field in Frankfurt

Corporate Sustainability Handprint at GIZ field in Frankfurt Outside Germany, GIZ teams use the Corporate Sustainability Handprint (CSH), a management tool that tracks both footprint (energy, water, travel) and handprint (active contributions such as solar arrays, carpooling, and fair procurement) in Frankfurt. Sustainability officers embed CSH targets in job roles so field offices contribute to the company-wide Sustainability Programme. What you can do - NGOs and development agencies: adapt the footprint/handprint split for your own country offices, track consumption and positive projects side by side - Municipal climate teams: borrow CSH indicators for embassies, twin-town partnerships, or international NGO hubs in your city - Workplace green teams: list one measurable handprint project per quarter (bike racks, PV, reusable event kit) How it works Country offices report CSH categories aligned with climate, procurement, and biodiversity goals. Handprint projects make visible what staff build, not only what they consume. Why it matters Corporate sustainability sticks when offices compete on contributions, not just compliance spreadsheets.

Balcony Solar Network

Bulk-buy balcony solar with your neighbours Connect with people in your building to research plug-in panels, share mounting help, and walk the Vienna registration steps together before anyone plugs in. What you can do - Host a roof or courtyard info session so neighbours compare kit specs side by side - Read the Wiener Netze balcony rules and register your Kleinsterzeugungsanlage (up to 800 W) before operating - Check the city balcony-module notes: Vienna does not subsidise balcony kits; city grants target fixed plants over 1 kWp with their own metering point - If your building wants to share rooftop generation beyond plug-in kits, book free energy-community advice from the Klima- und Innovationsagentur Wien (templates also at energiegemeinschaften.gv.at) How it works Austria treats plug-in balcony kits as Kleinsterzeugungsanlagen (max 800 W). Wiener Netze has two weeks after registration to check or swap the meter; Schuko / Schutzkontaktstecker connections are not allowed. After that, households on the same facade can split delivery and mounting. Larger shared plants belong in an Energiegemeinschaft, not a balcony kit. Vendor-neutral detail also lives at erneuerbare-energie.wien. Why it matters Collective buying lowers cost and fear of the unknown. Neighbours who compare kits and paperwork together are the ones who actually get panels on the railing.

Plan circular demolition in Roskilde

Plan circular demolition in Roskilde In Roskilde, you can see how circular demolition was planned at Musicon, the old concrete works the city bought in 2003. A pre-demolition audit of Hall 12 listed what could be used again before the selective take-down began. What you can do in Roskilde - Walk the Musicon district and see old factory ground turned into a neighbourhood (CityLoops on circular demolition) - Ask the city to require a material audit before the next public building comes down - Read the two CityLoops guides: one for the audit, one for selective demolition - If you own a building, use the Copenhagen Værdibyg guide to set a reuse aim before you tender the job (Værdibyg circular demolition booklet) - Ask designers to look at the audit while they draw the next building How to join Musicon is a public district of about 200,000 square metres, a former concrete factory and gravel pit. The city did not lock it to one fixed plan. Projects grow step by step with residents, builders, and the municipality. Hall 12 was audited by Golder: a desk study, then a field study, then a list of how to handle each material, including a store of saved parts. You can walk the district. You cannot join the Hall 12 works as a volunteer day. The audit is the pattern to copy. Why it matters in Roskilde An early list stops good doors, timber, and steel from being treated as rubbish. CityLoops found that contractors do not add this audit on their own after the contract is signed, so the city has to ask for it in the tender. A Danish client can follow the same idea with the Værdibyg steps: set an aim, survey resources, and write the handling rules into the tender. Find more community projects in Roskilde. Good to know - What is a pre-demolition audit? It is a list of materials, how much there is, how clean they are, and whether they can be used again, recycled, or must be treated as harmful. CityLoops says reuse is hard to promote without that list. - When should the first clear-out happen? As soon as the last user has left, before damp and vandalism spoil loose items.
