EMERGA is a collaborative community of researchers, students, core professionals across Universities and Industries and Government Agencies all over the world. It is a world-need program with an African bias, structured to fill the gap of indigenous research efforts in the global search for sustainable development in the health, environment and energy sectors. We work across disciplines and departments to create transformative knowledge for the environment and its people. Our vision is to expand scientific knowledge and develop innovative strategies and technologies that will strengthen Africa’s role in creating indigenous solutions to its numerous energy and environmental needs. The group is interested in five core areas of research in Environmental Science and Energy Technology which are Atmospheric, Earth and Aquatic Sciences, Ecosystem Science, environmental data science and systems, renewable energy systems, human health and environmental analysis.

In this field the group’s interest is to create new knowledge across multiple scales to aid decision-makers on the management of air, water, and land resources.

At the renewable energy levels, we consider analyses that will produce tools that address key issues at the intersection of environment, energy, science, technology, society, and policy..

We conduct analyses to assess emerging technologies and products and develop methods for identifying and managing the hazards of energy projects, as well as the disposition of their related wastes.

Energy is the livewire of today’s society and economy. Our work, leisure, and our economic, social and physical wellbeing all depend on the sufficient, uninterrupted supply of energy. In spite of the obvious negative impact of current energy systems to the environment, the demand for energy continues to grow, year after year. Traditional energy sources such as fossil fuels are hurting the environment. Besides, they are limited in quantity and the growing gap between increasing demand and shrinking supply will have to be filled by alternative primary energy sources. We are therefore constrained to seek and strive to make energy supply safer and more sustainable in order to avoid the negative impacts of global climate change, the growing risk of supply disruptions, price volatility and air pollution that are associated with today’s energy systems

The energy policy at the international scene advocates securing energy supply while at the same time reducing emissions that are associated with pollution and climate change. There have been calls to inhibit the emission of greenhouse gases and promote environment friendly energy sources, employ alternative fuels for transport as well as increase energy efficiency. Though carbon credit and public advocacy are attempts at preserving the natural environment, the exercise is still very far from the goal as the demand for land, timber and fuel wood continue to out grow conservation efforts.

A coherent energy strategy is required to address both energy supply and demand, taking into account the whole energy life-cycle including fuel production, transmission and distribution, and energy conversion, and the impact on energy equipment, manufacturers and the end-users of energy systems. In the short term, the focus should be higher energy efficiency and increase supply in renewable energy systems.

To conserve the global environment and achieve a sustainable society, it is necessary to limit the exploitation of the natural environment to a level within the Earth’s self-recovery capabilities. To meet this requirement, every part of the world must be actively involved in a vision that promotes environmental conservation. Concerted efforts aimed at developing energy systems with enhanced conversion factors must be backed up with research funding from within and supported by international donor agencies which could come as aids to weaker societies. This strategy is urgent because current renewable energy systems have failed to deliver adequate supply of energy to a society whose energy needs are growing by leaps and bounds.

About us

EMERGA is composed of a diverse and complementary array of professionals and service providers including Scientist, Engineers, Environmentalist, Information Experts, regulatory experts, and laboratories. From these experts we form research teams with specific mandates and projects to execute. The teams also work with our clients’ and funding agencies’ special needs, assuring project completion in a timely and most cost effective manner. We provide a wide range of intelligent management, specialized consulting, and technical services in the energy and environmental fields.

EMERGA research group is strongly pragmatic, evidence-based and scientific; its interdisciplinary composition encourages inter faculty and inter university based research. It also encourages national and international collaborations. The effect of such a combination is hard to quantify. Our approach integrates field and laboratory methods with the development of new theory, modelling, data systems, policy analysis, and evaluation to create solutions to complex environmental and energy challenges.

EMERGA network of alliances makes it possible to provide the widest range of “strategically and technologically available” services and reliable research work. Our environmental services include special expertise in environmental impact assessment, environmental auditing, remediation of energy related pollution including their community relations’ component and development of energy systems.

Igwe Ewona is a Professor of Atmospheric and Energy Physics with extensive research interest in air quality, pollutionepidemiology, climate change and mitigation. He is a winner of over 18 research grants, notably, the TETfund NRF research grant of 2014, where he and his team worked on "Characterization of Air Quality Parameters in the Niger Delta Area of Nigeria." The results show elevated concentrations of PM2.5 and PM10 generally believed to be responsible for several respiratory and heart related diseases. He is presently the Director, Directorate of Research and Development, Cross River University of Technology, Calabar where he has mobilzed over 100 IBR research grants to his University within two years in office. He is passionate about contributing to finding solutions to national issues. In 2020 grant cycle his NRF concept note was accepted but the project could not be funded citing paucity of funds. He believes that the current project will contribute to the United Nation’s sustainable development goals in the area of Health and wellbeing.

Prof. Ewona pioneered environmental monitoring and energy research group which has recently targeted atmospheric pollution through strategic project development and these have earned them some grant support.
