Dr. Kanto Razanamalala, a recipient of the 2020 Young Researcher Award from the Foundation for Research on Biodiversity (FRB), is working to address food insecurity in Madagascar through her research on soil biodiversity. Her project focuses on identifying bacteria and fungi in the soil that transform organic matter into nutrients for plants, ultimately improving soil fertility. This research aims to promote sustainable agricultural practices that prioritize soil health.
The FRB's Young Researcher Award recognizes young scientists who are actively engaged in biodiversity research and its associated societal challenges. The award is part of a larger effort to establish partnerships between public institutions, companies, and society to produce useful knowledge for action. Dr. Razanamalala's project was selected by the French Global Environment Fund (FFEM), which supports initiatives that combine local and scientific knowledge to address environmental challenges.
Dr. Razanamalala's thesis explored the identification of bacteria and fungi in the soil and their activities that transform organic matter into nutrients for plants. By analyzing soil samples and microbial biodiversity, her research aimed to identify agroecological practices that can promote beneficial microorganisms in the soil. Her findings showed that climate, soil conditions, and agricultural practices influence microbial processes that affect soil fertility.
The results of Dr. Razanamalala's research have significant implications for farmers in Madagascar. She found that tillage can disrupt microorganisms involved in nutrient storage, leading to decreased soil fertility over time. In contrast, adding compost to the soil promotes the development of beneficial microorganisms, allowing for nutrient storage and improved soil health. These findings highlight the importance of considering soil biodiversity in the development of sustainable agricultural practices.
Dr. Razanamalala's research also contributes to the broader understanding of soil biodiversity in Madagascar. Currently, only 1% of soil organisms have been identified, and this lack of knowledge has significant implications for food security and environmental sustainability. Her research is among the first in Madagascar to study the molecular diversity of soil bacteria and fungi, identifying microorganisms linked to soil fertility processes.
The outcomes of Dr. Razanamalala's project have been used to develop a decision-support tool for technicians and farmers to visualize the long-term impact of different agricultural practices on crop yields and soil fertility. This tool can help promote sustainable agricultural practices that prioritize soil health and biodiversity. Future research will focus on extending her findings to new regions of Madagascar, identifying and disseminating adapted agroecological practices that balance food security and soil conservation.
Dr. Razanamalala's work has the potential to make a significant impact on food security and environmental sustainability in Madagascar. By promoting sustainable agricultural practices that prioritize soil health, her research can help reduce food insecurity and protect the country's natural resources. Her findings also highlight the importance of continued research into soil biodiversity and its role in maintaining ecosystem services.
