+# Mali: Operational Presence
+
+**Publisher:** OCHA Mali · **Source:** [HDX](https://data.humdata.org/dataset/mali-operational-presence) · **License:** `cc-by-igo` · **Updated:** 2025-08-06

+## Abstract
+
+The Who does What Where (3W) is a core humanitarian coordination dataset. It is critical to know where humanitarian organizations are working and what they are doing in order to identify gaps and plan for future humanitarian response. This dataset includes a list of humanitarian organizations operating in Mali at Admin 3.
+
+Each row in this dataset represents subnational administrative unit observations. Data was last updated on HDX on 2025-08-06. Geographic scope: **MLI**.
+
+*Curated into ML-ready Parquet format by [Electric Sheep Africa](https://huggingface.co/electricsheepafrica).*

+## Variables
+
+**Geographic** — `organisation_accronyme` (UNICEF, OMS, USAID), `type_organisation` (ONG int, Agence UN, ONG Nat), `admin1pcod` (ML05, ML04, ML03), `region` (Mopti, Segou, Sikasso), `admin2pcod` (ML0502, ML0305, ML0506) and 1 others.
+
+**Identifier / Metadata** — `esa_source`, `esa_processed`.
+
+**Other** — `nom_organisation` (Fonds des Nations Unies pour l'Enfance, Organisation mondiale de la santé, U.S. Agency for International Development), `cercle` (Bankass, Sikasso, Mopti), `commune` (Gao, Ansongo, Koro), `cluster` (Santé, Protection, Secal*).

+## Quick Start
+
+```python
+from datasets import load_dataset
+
+ds    = load_dataset("electricsheepafrica/africa-mali-operational-presence")
+train = ds["train"].to_pandas()
+test  = ds["test"].to_pandas()
+
+print(train.shape)
+train.head()
+```

+
+## Curation
+
+Raw data was downloaded from HDX via the CKAN API and converted to Parquet. Column names were lowercased and standardised to snake_case. Common missing-value markers (`N/A`, `null`, `none`, `-`, `unknown`, `no data`, `#N/A`) were unified to `NaN`. 1,287 exact duplicate rows were removed. The dataset was split 80/20 into train and test partitions using a fixed random seed (42) and saved as Snappy-compressed Parquet.
+
+---
+
+## Limitations
+
+- Data originates from OCHA Mali and has not been independently validated by ESA.
+- Automated cleaning cannot correct for misreported values, definitional inconsistencies, or sampling bias in the original collection.
+- Refer to the [original HDX dataset page](https://data.humdata.org/dataset/mali-operational-presence) for the publisher's own methodology notes and caveats.
