Lake Andraikiba is the largest lake in the Vakinankaratra Region of Madagascar with an average depth of 34.38 m and a volume of 34.8 million m3. The lake provides 49% of the drinking water to the Urban Municipality of Antsirabe I with a flow rate of 500 m3/h operated by the local utility, JIRAMA. Its watershed of 128 ha hosts diverse land uses and the lake itself supports irrigation and fishing with a clear tourist potential.

However, the lake edge and its watershed are largely deforested, driven primarily by population growth and the intensification of agro-pastoral activities. As a consequence, soil erosion and subsequent sediment transport to the lake have increased over time. Sediments and eroded material may contain heavy metals and toxic substances, nutrients, and organic matter, with consequences for the lake’s ecosystem and societal functioning. Moreover, population pressures also have led to increased water withdrawals from the lake over the past 20 years (a total of 48.6 million m3 from 1997–2017). Taken together, these effects have reduced the reservoir’s storage capacity, led to clogging of piping and ducts by sediment, reduced dam safety, caused changes in lake hydrological regime and biodiversity, and affected water security for human settlements.

To address these issues, the consultant shall prepare a series of deliverables that include reports on remote sensing on Lake Andraikiba and recommendations for UNESCO World Water Quality Portal in Madagascar. The incumbent is expected to undertake remote sensing/GIS and data management aspects of this initiative and will also visit the field site to collect data with field campaigns.

Under the overall authority of the Director of UNESCO Regional Office for Eastern Africa, under the overall supervision of the Head of Natural Sciences sector and the direct supervision of
Associate Programme Specialist in Antananarivo Antenna, in close collaboration with the national coordinator of the Antenna and Associate Project Coordinator of IHP programme, the incumbent is expected to specifically render the following three deliverables:

1. A Baseline Report containing:
a. A report on the types, availability (e.g., accessibility, data location, data duration), and sources of data that could support a satellite-based or remote sensing analysis of water quality in Lake Andraikiba, with sources’ address and contact details of people in charge of the databases
b. A summary analysis of the available water quality data, with particular focus on optical properties (e.g., chlorophyll a, turbidity, total suspended sediment, Secchi depth, water temperature, colored dissolved organic matter). The analysis should include the method used to obtain the result with information on the detection limits. The analysis shall be reproducible.
c. A summary analysis of the available remote sensing data (e.g., Landsat, Sentinel I and II) with spectral information, pixel size, number of cloud-free days available for match-ups between in-situ and satellite data. See: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2019WR024883. The analysis should include a section on what type of data are currently being used by the Ministry and the Universities and the contact persons responsible for the data collection, analysis and storage.
d. An analysis of water treatment systems in the watershed, including methods, efficiencies, and water quality, water flow, and loading of effluent.

2. A Current Capacity Report on Madagascar’s current capacity to acquire, process and analyze, and understand remotely sensed and in-situ water quality data. This will explicitly include:
a. An analysis of the Ministry of Water, Sanitation and Hygiene’s and leading Universities and research centers in the country, current capacity to collect and process water quality data and satellite imagery. This can include an informal survey and should take into consideration capacities both at National and Regional levels.
b. A Capacity Building Assessment Report for the Ministry of Water, Sanitation and Hygiene and of leading Universities and research centers in the country, to be able to manage remote sensing data against Deliverable 1. What skills and capacities are needed for the Ministry to be able to develop, improve, or expand their ability to acquire, process, and analyze satellite imagery related to Lake water quality and hydrology? What timeline is reasonable? What budget is reasonable? What capacities lay in the Universities? Could we use a training of trainer’s approach
