Conservation

"Conservation, study of the loss of Earth’s biological diversity and the ways this loss can be prevented. Biological diversity, or biodiversity, is the variety of life either in a particular place or on the entire planet Earth, including its ecosystems, species, populations, and genes. Conservation thus seeks to protect life’s variety at all levels of biological organization." (Pimm 2020)

Monitoring runoff using Earth observation data

When rain falls on Earth, the water starts moving and flowing downhill through sewers and rivers as runoff. Runoff is extremely important to recharge surface water bodies and groundwater. Furthermore, runoff changes the landscape by action of erosion. It is an integral part of the water cycle (Earth Science Data Systems 2021). 

Why space gardening should come down to Earth

When you think about agriculture, you probably imagine a few basic things in your mind. Huge stretches of flat land, massive harvesting machines, the heat on your skin from sunlight and, perhaps most importantly, soil. This image in your mind is a common one. Humans have been tilling, seeding, and farming land since the dawn of civilization, and modern industrial farm techniques tend to dominate our conception of agriculture. 

Pourquoi Devrions-Nous Utiliser le Jardinage de l'Espace sur Terre

Merci à Martin Sarret d'avoir traduit cet article volontairement.

Les caractéristiques élémentaires de l´agriculture nous viennent tous assez facilement à l´esprit. De larges étendues de terrain, d'imposantes machines de récolte, la chaleur du soleil sur la peau et, peut-être le plus important, la terre. Cette image mentale est finalement assez logique. L´humanité laboure, ensemence et cultive la terre depuis la nuit des temps, et les techniques agricoles industrielles modernes ont tendance à s'accaparer notre imaginaire sur l'agriculture.

Interview with Dieudonne Ilboudo, Water and Environment Specialist, General Office of Agro-Pastoral Development and Irrigation of Ministry of Agriculture, Animal and Fisheries Resources of Burkina Faso

This interview provides an in-depth look at my expertise and experience in water resource management, environmental conservation, and the integration of AI and remote sensing technologies in Burkina Faso. My passion for water management stems from my desire to protect precious resources and my belief in the essential importance of providing water to communities, a principle reinforced when I joined the Ministry of Agriculture in 2021. As a Water and Environment Specialist at the General Office of Agro-Pastoral Development and Irrigation, I am responsible for irrigation systems, lowland rice-growing areas, and the protection of water infrastructure, while integrating innovation and remote sensing technologies to improve performance. My work also focuses on community conservation, including the removal of invasive aquatic plants from reservoirs and the treatment of gullies to combat soil erosion. I have experience in remote sensing and AI-based applications such as ML and DL for monitoring flood risks, erosion, and irrigation systems. I use machine learning algorithms such as CNN, Random Forest, U-Net, and SVM to analyze satellite images, predict the spread of invasive plants, and optimize water use. My research on integrating traditional knowledge into water management highlights the SoaSoagha concept, a collective work approach in Burkina Faso that promotes community conservation. Traditional rainwater harvesting, floodplain management, and small earthen dams (soussous) align with modern hydrological models, while sacred forests and customary water rights have been revealing, demonstrating indigenous methods of ecosystem protection. My project on AI-powered aquatic invasive plant management integrates machine learning (Satellite image analysis to classify areas with a high probability of aquatic plant presence), deep learning (Precise segmentation of invasive plants, such as water hyacinth and others, in these identified areas), and community engagement to extract, classify, and convert plants into compost, biogas, and biochar. My work highlights the importance of combining technological innovation and traditional knowledge to strengthen climate resilience, ensure water security, and promote sustainable development in Burkina Faso and beyond.

Outline steps for a solution

Phase 1: Planning and Stakeholder Engagement – To do

The first phase involves defining the objectives of the monitoring system and identifying measurable success indicators aligned with conservation priorities and local needs. This is followed by engaging key stakeholders such as the National Environment Management Authority (NEMA), Kenya Wildlife Service (KWS), Water Resources Authority (WRA), Nyandarua County Government, and local community-based organizations. Stakeholder consultations are critical for gathering input on data needs, identifying decision-making gaps, and ensuring buy-in from both policy actors and community leaders. A situational analysis should be conducted to map existing infrastructure, technical capacity, internet access, and human resources available on the ground, helping to identify opportunities and constraints for implementation.

Phase 2: Data Collection and System Design – In progress

In this phase, a comprehensive monitoring framework is developed, specifying the key indicators to be tracked, such as seasonal water extent, land cover transitions, and flood-prone zones. Relevant Earth observation datasets are selected, including Sentinel-1 SAR for water extent, Sentinel-2 for habitat classification, JRC Global Surface Water for historical trends, and CHIRPS for rainfall data. A prototype dashboard is developed using Google Earth Engine, visualizing these datasets through maps, time series graphs, and interactive overlays. Simultaneously, field validation activities are conducted to ground-truth satellite-derived maps. This includes collecting GPS points, photos, and observations on vegetation, land use, and visible signs of degradation, ensuring the remote sensing outputs are accurate and contextually relevant.

Phase 3: System Testing and Expansion – To do

Once the prototype is ready, it is tested with stakeholders through pilot sessions and community workshops. These engagements are used to collect feedback on the dashboard’s usability, relevance, and user experience, particularly for non-technical audiences. Revisions are made to improve clarity, layer toggling, labelling, and interpretability. In parallel, basic physical interventions begin, such as the installation of simple water gauges, informational signboards, and boundary markers for conservation zones. These elements help translate digital insights into tangible tools for the community. Plans for expanding field infrastructure, such as creating buffer zones or establishing a local conservation hub, are also explored during this phase.

Phase 4: Deployment and Knowledge Sharing – In progress

Following successful pilot testing and system refinement, the full monitoring platform is deployed on a publicly accessible hosting environment, such as Firebase, Earth Engine Apps, or a custom-built website. The platform is shared with agencies and conservation partners, accompanied by a rollout plan that includes formal training sessions. These capacity-building workshops are designed to empower users, ranging from government officers to youth groups, with the skills to interpret dashboard outputs and use the data in planning and response. User guides, translated materials, and offline summaries are provided to support long-term usability and local ownership.

Phase 5: Monitoring, Maintenance, and Scaling – To do

The final phase focuses on monitoring the performance and real-world impact of the system. Regular evaluations are conducted to assess usage, data accuracy, stakeholder engagement, and improvements in environmental decision-making. Lessons learned are used to refine system features, add new datasets, and introduce functionalities such as alert notifications or mobile-friendly access. The success of the Lake Ol’ Bolossat solution creates a foundation for scaling to other endangered wetlands across Kenya, such as Lakes Baringo, Naivasha, or Kanyaboli. Finally, the project contributes to the broader Space4Water and open science communities by publishing methods, code, and findings on platforms like GitHub and Earth Engine’s asset repository, ensuring transparency, replicability, and collaboration.

Results

The Lake Ol’ Bolossat monitoring system, currently at prototype stage, holds significant potential to transform how freshwater ecosystems are managed at local and national levels. By integrating satellite-derived water and habitat data into an accessible dashboard, the system aims to bridge the gap between Earth observation science and on-the-ground conservation action. Once implemented with key stakeholders and end users, the following impacts are anticipated:

  1. Support for Environmental Agencies and County Governments: The system could enhance the capacity of institutions such as the National Environment Management Authority (NEMA), Kenya Wildlife Service (KWS), Water Resources Authority (WRA), and the Nyandarua County Government by providing timely, location-specific data for decision-making on lake and wetland management.
  2. Early Warning for Hydrological and Ecological Risks: The dashboard could enable stakeholders to detect abnormal patterns in water extent, such as persistent shrinkage or sudden expansion, triggering early intervention to prevent ecological degradation or disaster impacts on nearby communities.
  3. Community Awareness and Engagement: By visualizing seasonal and long-term changes, the system can be used to build awareness among residents, farmers, and water users around Lake Ol’ Bolossat, empowering them to engage in sustainable practices and to advocate for the protection of the lake.
  4. Policy-Relevant Monitoring Tool: The platform can serve as a long-term environmental monitoring tool to support the implementation of wetland protection policies, local water catchment strategies, and integrated land use planning frameworks.
  5. Scalability to Other Freshwater Ecosystems: Once validated, the approach used at Lake Ol’ Bolossat can be adapted to other small inland water bodies across Kenya and East Africa, particularly those facing similar risks of drying, encroachment, or biodiversity loss.
  6. Alignment with Global and National Development Goals: The system supports Kenya’s contributions to Sustainable Development Goals (SDGs), particularly:
  • SDG 6: Ensure availability and sustainable management of water and sanitation
  • SDG 13: Take urgent action to combat climate change and its impacts
  • SDG 15: Protect, restore and promote sustainable use of terrestrial ecosystems and halt biodiversity loss
