Where you’ll be

Sumba, Indonesia

What is not publishedthe gaps we looked for and did not find

Four of the eight pathways have nothing published and score zero: Water Integrity, Light Rhythm, EMF Harmony, and Sound and Sensory Ecology. On water, the property publishes that 90 percent of its wastewater is reused to irrigate the farm, which describes disposal and irrigation rather than the water a guest drinks or bathes in. No water source, treatment train, filtration specification, laboratory panel or swimming pool sanitation method is published. On EMF, Wi-Fi is listed among the shared facilities and no network topology, access point placement or field reading is published; the 288 solar panels are an energy disclosure and say nothing about the wireless environment. No lighting specification, colour temperature, flicker or blackout provision is published, and no background noise level, acoustic separation or fragrance policy is published. On air, both room types are listed with a fan and air conditioning as well as an en suite open air bathroom, and no filter grade, ventilation rate, carbon dioxide, particulate or volatile organic compound reading is published; no combustion source inside the guest envelope is described either way. On materials, no mattress composition, linen fibre content, textile certification, paint, adhesive or cleaning and laundry chemistry is published. On food, no cooking oil policy, cookware, kitchen or ice water specification and no additive or allergen position is published. The Archello project page for this campus could not be read because it is behind a bot verification challenge, which was not bypassed; its content is therefore unassessed rather than absent.

Regional context2 public figures about the area, none of which scores

Public data about the surrounding area. None of it contributes to the score, because a property cannot be marked down for the conditions outside it.

Safely managed drinking water, Indonesia: The World Health Organization reports 30 per cent of the population nationally, 35 per cent in urban areas, 24 per cent in rural areas using a safely managed drinking water service. This describes the country, not this property, and says nothing about what reaches a guest room here. It is recorded because it is the background against which a property's own treatment is worth publishing. Source
Ambient PM2.5 and PM10 near Sumba, Indonesia: Modelled ambient air over this location averaged 9.6 micrograms per cubic metre of PM2.5 and 13.3 of PM10 across the 720 hours to 2026-08-17, peaking at 19.8 PM2.5. The World Health Organization annual guideline for PM2.5 is 5. This is the outdoor air over the area, modelled rather than measured on site, and it is not a reading of the air inside any room.

Not published is not unsafehow to read these scores, and what this index does not promise

A low score means a property has not published information. It does not mean the property is unsafe, unhealthy or poorly run.

These scores measure disclosure. These scores describe disclosure, not property quality. This index has no commercial relationship with the properties listed unless a badge on the listing says otherwise.

Conditions change, and we will not always know. Every record is a snapshot of what a property had published when we read it, and that date is on the page. Conditions change: a property can refit, change suppliers or replace a system at any time, and nothing requires it to tell us. We re-read records and ask properties directly for updates, but there will always be a gap between what is true today and what was published when we looked. Use this as a frame of reference for what to ask, not as a substitute for asking. Take your own questions to the property before you book, and tell us if you find something we have wrong.

We report what properties publish. We do not inspect, certify or vouch for any property on this index unless a listing says we assessed it on site, and we accept no responsibility for decisions made or outcomes experienced on the basis of what you read here.

Questions travelers askwater, air, EMF, and whether it is worth it

Does Sumba Hospitality Foundation publish water quality testing?

No. Nothing is published, and we looked. That is a statement about the public record, not about safety.

What is the air quality like in the rooms?

We can only report what is published about the rooms themselves. It is claimed but not specified: the property asserts it without naming a system, supplier or measurement. Scored 1 of 3.

Is Sumba Hospitality Foundation low-EMF?

No measurement is published. Only 14 of the 70 properties we have researched publish any bedroom EMF information at all, so this is the industry norm, not an outlier.

Is Sumba Hospitality Foundation worth it?

We score evidence, not experience. On evidence, it ranks 53 of 70 researched records. The strongest documented pathways are Materials and Textiles and Food and Kitchen; nothing is published on Water Integrity or Light Rhythm.
