Day 72: In Papua you can never be sure about schedules and timing until the ship has actually taken off. After an obligatory 3 hour delay, I am eventually about to embark for the previous to last stage of my journey: 4 days of navigation over a 1,100km route: Lae-Umboi-Gloucester-Kimbe-Rabaul. I still don't know how to manage the last stretch from Rabaul to Buka....

I can't believe that after 70 days of travel I am just about to complete the 28,000km dividing Italy from the Solomons without flying! It will count nothing in terms of overall greenhouse emissions, but for me, now, it's everytghing I can do to for this wonderful fragile planet. 91/

I slow travel mainly to reduce my carbon footprint (by 10 times according to available estimates) but also to experience travel as most people in this world do.

There are no bus schedules, no tickets, and buses depart when they are full. I am getting to the main departing point in Madang when it's already late in the morning - but I really wanted to talk about locals about coastal erosion in the city. Fortunately, I still find a place for me on probably the last bus, and two seats are allocated to my bulky luggage. Off we go for the last stop in Papua island before hopefully embarking for the Bismarck archipelago.

It takes 6 hours to cover 212km on "Ramu Sugars" road. It was even slower 3 yrs ago with unpaved track

The PNG government's decision to close Taiwan's representative office signals a further contraction in Taiwan's diplomatic space. It indicates that China is no longer just targeting Taiwan's small number of diplomatic allies, but Taiwan's much larger network of representative offices

We’re going to need some legal word smithing on the order of the #GPL and the #CreativeCommons licenses to make a false statement an offence in as many ways and jurisdictions as possible (any ideas, #lawFedi folks?), some #EXIF and #ID3v2 and #PNG and comparable metadata tags for carrying legal statements attesting to non-use of media synthesis (mislabelled as #genAI by GPT vendors and NPU/TPU manufacturers), some apps to interview and educate the user about media provenance and add those tags iff applicable, and some #Fediverse and web browser add-ons to filter out media lacking them unless verifiably produced before a given date.

Times of India highlights 30 years of PNG:
"This suggests that many technological breakthroughs build on existing systems. The format was not a universal replacement for all other forms of graphic files, but the combination of openness, precision and clarity of the PNG format made it a trustworthy standard that developers could use everywhere."

Day 65: After a smooth 9-hour boat ride over the Sepik river, we made it to Sisimagung, Northern Papua. This is the 65th day of my no-fly trip from Italy to the Solomon islands. The coastline is beautiful, what you could describe as paradise on earth. Coconut trees gently bend over sandy beaches and the sound of the waves quietly resound among villagers busy with their fishing nets or cooking earths. It is then all the more upsetting that this beauty is slowly but incessantly being destroyed by sea level rise. This is what Jeffery Bae, a local resident, tells me in the few hours I have here before getting on a truck to Madang. It seems impossible that a sea so quiet can become the agent of destruction, but this is precisely what happens, as Jeffery shows traditional houses made with sago and bamboo leaves having been dismantled by the latest storm surges.
"We will have to relocate", tells me Jeffrey with an empty, "but we don't know where, because right behind our village there's a swamp".
Once more, I hear the same story: no help from national, regional governments, and neither from international organisations.
How many million stories are similar to Jeffrey's, and I wouldn't hear were it not for my slow travel.

A split-surface over-under photograph by Renee Capozzola captures a traditional outrigger canoe floating above a thriving coral reef. In the top half, a person wearing a bright, colorful sarong sits aboard the wooden canoe on calm, sunlit water, with dense green mangrove forests lining the shore under a bright blue sky.

Here's a backing sheet printout I made. You can see it through the sheet you're typing on and know when you're getting close to the end of a line, the center of the page, and the diagonal line gets closer to the right as you get closer to the end of the page. 1"-ish margins.

Day 65: I cross the Sepik river in a 9-hour night boat ride. I didn't know it was possible to sleep comfortably on betel nut bags, but it is. The quiet of the sunrise in the foggy dimmed-light awakening will never die in me. So the warmth of the fellow passengers and the skipper Bendol. Incidentally, his torch faded away soon after setting off. What would he have done if I hadn't lent me my own torch to navigate the boat in the night? This is typical Papua: no thinking about the future, everything will be alright.

I slow travel mainly to reduce my carbon footprint (by 10 times according to available estimates) but also to experience travel as most people in this world do.

The original plan was to take a boat straightaway after my arrival in Angoram, in the Sepik river, but I thought I'd better take a rest instead - even if I had nothing booked. the local priest put me up and in the morning local guy Morgan shows me arob Ng the local market, open everyday. the main food from here is sago, a tree from the palm oil family, from which the locals take almost everything. from the internal pulp that is eaten raw or processed to make flour, to its leaves that are used to make up houses' roofs.
