He is The African ADR Practitioner of the Year 2022, The African Arbitrator of the Year 2022, ADR Practitioner of the Year in Kenya 2021, CIArb (Kenya) Lifetime Achievement Award 2021 and ADR Publisher of the Year 2021 and Author of the Kenya’s First ESG Book: Embracing Environmental Social and Governance (ESG) tenets for Sustainable Development” (Glenwood, Nairobi, July 2023) and Kenya’s First Two Climate Change Law Book: Combating Climate Change for Sustainability (Glenwood, Nairobi, October 2023), Achieving Climate Justice for Development (Glenwood, Nairobi, October 2023) and Promoting Rule of Law for Sustainable Development (Glenwood, Nairobi, January 2024)*
It has been observed that science and technology have enhanced the response to the global threat of climate change in various ways including emissions reduction which involves tackling climate change by reducing greenhouse gas emissions; sequestration which entails removing carbon dioxide from the atmosphere into permanent geological, biological or oceanic reservoirs; adaptation through responding to and coping with climate change as it occurs, in either a planned or unplanned way; and solar geoengineering through large-scale engineered modifications to limit the amount of sunlight reaching the earth, in an attempt to offset the effects of ongoing greenhouse gas emissions .
Further, science and technology are enhancing low carbon development in various sectors. Low carbon development refers to forward-looking national economic development plans or strategies that encompass low-emission and/or climate-resilient economic growth. Low carbon development has also been defined as long term climate-friendly growth strategies that can highlight a country’s priority actions for climate mitigation and adaptation, and a country’s role in the global effort against climate change. Low-carbon development aims to achieve the goals of reducing greenhouse gas emissions, exploiting low-carbon energy, and fostering economic growth. Scientific research and technological innovation have enhanced low carbon development through the development of clean and green technologies and climate smart practices in various sectors including energy, agriculture, transport, infrastructure, industry and biodiversity conservation.
Science, technology and innovation have enhanced energy efficiency through the development of clean sources of energy such as renewable energy. The energy sector is the central front in the battle to mitigate greenhouse gas emissions. As a result, it has been rightly pointed out that cleaner technologies, including cleaner energy technologies, have an important role to play in addressing climate change. Clean energy technologies especially renewable sources of energy such as solar energy (solar thermal, solar photovoltaic, high efficiency solar cells), energy from urban and industrial wastes, wind, biomass (bio-fuels, bio-gas, waste to energy) and small hydro, ocean and geothermal energy and new technologies including fuel cells and hydrogen have enhanced global efforts towards tackling climate change.
It has been observed that clean energy technologies such as renewable sources of energy emit little to no greenhouse gases and have made massive strides in performance and cost, making it more feasible than ever to shift the world away from burning fossil fuels at a faster pace than previously thought. Further, it has been asserted that these developments have increased the economic attractiveness of low-emission energy sector transitions towards combating climate change. It is therefore important to effectively embrace clean energy technologies in order to strengthen the global response to climate change. Science and technology is also enhancing low carbon development in the transport and infrastructure sector through low carbon infrastructure and green transport models.
It has been estimated that approximately 79% of global greenhouse gas emissions come from infrastructure construction and operations such as power plants, buildings, and transport. In order to curb this situation while maintaining infrastructure as a priority sector for climate action, and national growth in general, climate experts have argued that governments need to radically rethink how infrastructure is planned, delivered and managed in order to make it suitable for a low emission and resilient future. Scientific research and technological innovation have tried to address this concern through the development of low carbon infrastructure projects such as railway infrastructure and urban transport projects including metros and light rail projects which reduce motor vehicle usage.
Science and technology are revolutionizing the transport and infrastructure sector through the development of hybrid electric vehicles, battery electric vehicles, solar electric vehicles, fuel cell vehicles, improved diesel vehicles, alternative fuel technologies, material substitution technologies, smart traffic infrastructure/intelligent transport systems and the use of information technologies for traffic management. Further, in the infrastructure sector, there is increased adoption of green construction materials including flash-based bricks, RCC blocks, cellular lightweight concrete, bamboo-based materials and bagasse boards; efficient lighting system; and adoption of nature-based infrastructure. These measures have aided in the reduction of greenhouse gases and improved efforts towards tackling climate change.
Science and technology are also enhancing the response to climate change in the agriculture sector through climate smart agricultural practices which are geared towards enhancing the resilience of the agriculture sector and promoting food security while curbing greenhouse gas emissions. Advanced farming machinery; innovative farming techniques including zero budget farming, organic farming; smart irrigation technologies including drip irrigation and sprinkler irrigation; energy efficient farming technologies; the use of nanotechnology; mechanisation of horticulture; and scientific research in agricultural extension are some of the scientific and technological approaches that are enhancing the resilience of the agricultural sector and promoting food security while reducing greenhouse gas emissions.
Technologies such as genetic engineering have been adopted to transfer the nitrogen fixing capabilities of legumes such as peas and beans into cereal crops so to attain higher yields, without the use of expensive fertilizers towards curbing carbon emissions and environmental pollution. Scientific research and technological innovation have also increased the adoption of regenerative agricultural practices such as crop rotation, agroforestry, use of drought- and heat-resistant crops, integrated pest control systems, water harvesting and irrigation. This approach has helped in fostering high-yielding, resilient, and adaptive practices in the agricultural sector.
Science and technology have therefore played a pivotal role in tackling climate change in the agriculture sector. Science and technology have also enhanced the response towards climate change through carbon sequestration. Carbon sequestration involves removing carbon dioxide from the atmosphere and storing it into permanent geological into permanent geological, biological or oceanic reservoirs. Carbon sequestration can prevent further emissions from contributing to the heating of the planet. This concept happens in two forms: biologically or geologically.
Biological carbon sequestration happens when carbon is stored in the natural environment in ‘carbon sinks’, such as forests, grasslands, soil, oceans and other bodies of water. Geological carbon sequestration is an artificial process that involves removing carbon from the atmosphere and storing it in places such as underground geological formations or rocks. It majorly relies on technology with recent innovations such as graphene production and carbon capture and storage showing carbon being sequestered more effectively on larger scales. Carbon sequestration is therefore an important process in tackling climate change by removing carbon dioxide from atmosphere and storing it in order to mitigate its negative impacts on the planet. Science and technology are aiding in carbon sequestration.
In addition, science and technology are enhancing efforts to tackle climate change by fostering biodiversity conservation. The Convention on Biological Diversity recognizes the role of science and technology in the conservation of biodiversity and urges parties to foster and collaborate in areas such as scientific research, access to and transfer of technology and exchange of scientific information in order to enhance the conservation of biodiversity. Science and technology can enhance conservation of biodiversity through remote sensing, ex-situ conservation, biotechnology, bioremediation in order to restore damaged biodiversity, and information technology among others.
Finally, it has been pointed out that Artificial Intelligence (AI) is helping to reduce greenhouse gases at industrial facilities as part of the efforts towards tackling climate change. AI is enhancing improvements in energy efficiency, generation and storage, redefining energy systems, unlocking the possibility of data driven power options and enabling smart city development. It has been pointed out that climate data sets are enormous and take significant time to collect, analyze, and use to make informed decisions and enact actual policy change. Using AI to factor in elements of climate change that are constantly evolving can aid in making informed predictions about changes in the environment, in order to adopt mitigation efforts earlier.
AI is therefore one of the technological revolutions that can aid efforts towards tackling climate change. It is therefore evident that science and technology are viable tools in tackling climate change. However, it has been observed that developing countries continue to face barriers in accessing clean and climate friendly technology. Further, most countries especially in the developing world are yet to fully invest in climate science research and development hence hindering effective mitigation and adaptation efforts. It is imperative to effectively embrace science and technology in order to enhance the global response on climate change.
