In environmental science, innovation often comes out of necessity. For ecologist and researcher Dr. Mubarak Mahmud, whose areas of expertise are forestry, agroforestry, and climate change adaptation, the necessity to create a low-cost but highly accurate way of measuring tree height led to an award-winning innovation. His Mahmud Method is changing forestry research with its low-cost, scientifically accurate, and affordable alternative to established measurement devices such as clinometers and LiDAR.
Having a Ph.D. in Ecology from Université Paris-Saclay, France, and in one year of research background at the French National Research Institute of Agriculture, Food, and Environment (INRAE), Dr. Mahmud has dedicated his life to studying nitrogen fluxes, greenhouse gas emissions, and sustainable land-use practices. His most recent invention, the Mahmud Method, is already being integrated into forestry courses, conservation strategies, and climate change policies globally.
Innovation Born from Necessity
Dr. Mahmud was spurred into creating the technique due to the very high cost and lack of availability of classical tree height-measuring tools. Certain researchers, particularly from the developing world, have no access to costly LiDAR instruments or advanced clinometers, making measurement of the tree difficult.
“The Mahmud Method was born out of necessity,” Dr. Mahmud explains.
“Traditional tools are often expensive, require specialized training, or are simply unavailable in many parts of the world. My goal was to create an affordable, scientifically accurate, and easy-to-use alternative that empowers researchers, conservationists, and even local communities to conduct precise forestry measurements with minimal equipment.”
Scientific Foundation: Thales’ Theorem and Mathematical Precision
In essence, the Mahmud Method utilizes Thales’ theorem, a geometric principle whereby height is able to be calculated using proportions and triangulation. The method is acquired by having an image of a tree whose height can be used as a known reference object, e.g., a human or pole. By taking a measure of the relative size of each object, the method returns a height reading that is 0.998 correlated with recorded actual heights, which is just as good as more expensive machinery.
“Using Thales’ theorem, we reduce human error when manually measuring angles,” says Dr. Mahmud.
“This increases the technique to be more accurate than standard clinometers, without making it too complicated for anyone to use.”
M-Tree App: Smart Technology for Tree Measurement
To further simplify the Mahmud Method, Dr. Mahmud and his team have developed it into a mobile app called M-Tree. With the app, tree heights can be measured instantly using smartphone cameras. The app also features some innovative aspects:
Revolutionizing Nigeria, Africa, and Developing Nations Research
Forest research and environmental studies in developing nations, including Nigeria, have for a long time suffered from insufficient funding, inadequate access to research facilities, and difficulty collecting large amounts of data. Mahmud Method completes the void with a cost-effective, efficient answer to:
“In areas such as the Sahel, where trees outside forests (TOF) are important for carbon sequestration, desertification, and regulation of ecosystems, this approach allows for reliable estimation of biomass, enabling policymakers to make sound decisions,” says Dr. Mahmud.
Innovative Climate Change Reduction and IPCC Reporting
Mahmud’s Method is not only revolutionary for researchers, its potential extends to worldwide climate policy and carbon storage estimations. Careful measurement of the height of trees is key in order to:
“Many climate models underrepresent tree contributions in non-forest ecosystems because they lack ground data,” explains Dr. Mahmud.
“By making tree measurement more accessible, the Mahmud Method ensures carbon sequestration data to be more accurate and credible.”
Growing Impact: From Research to Policy and Conservation
Dr. Mahmud’s impact extends well beyond the laboratory. As a lecturer at Kano University of Science and Technology, Wudil, he is using the Mahmud Method in forestry and ecology courses to educate the future generation of environmental scientists how to employ sophisticated instruments to save the environment.
“My intention is to make students and young scientists understand that simple mathematical concepts can resolve actual environmental problems,” he states.
“With the addition of Mahmud Method in fieldwork training, we are making data-driven, precise forestry research the standard.”
The method is also being used in official land-use and conservation planning strategies already. It is being recognized globally at forestry institutions, and an official celebration event will be organized on April 30, 2025, at Université Paris-Saclay, France, to highlight its implication in forestry and environmental science.
Scaling Up and Overcoming Challenges
It was through extensive field testing, refining algorithms, and collaborating with app developers that the hurdles were finally overcome. Dr. Mahmud now aims to scale the innovation to global levels.
The Future of the Mahmud Method
As more research, learning, and environment policy-making become its applications, Dr. Mahmud’s horizons are wide:
Final Words
Dr. Mahmud’s study is an example that scientific advancement does not have to be costly in order to be pioneering. With the tree measurement made cheap, affordable, and precise, the Mahmud Method is revolutionizing forestry research, global warming prevention, and conservation efforts across the world.
“The Mahmud Method demonstrates that we can share science tools with everyone wherever they are or whatever resources they possess with the right attitude. This is not just a tool of a researcher; it’s a tool for the world to facilitate conservation, sustainability, and climate action worldwide.”
