Mathematics pervades every area of our modern world, bringing ever more sharply into focus the responsibilities placed on those who to teach it. Prominent among these is the challenge of developing an interdisciplinary approach, so that each professional group benefits from the expertise of others. Environmental Mathematics Unit (EMU) provides an environment for collaboration of researchers in Environmental mathematics to present, assimilate and eventually adapt environmental solution to everyday needs in schools, colleges, universities, industry, and commerce. EMU is especially interested in facilitating communication between researchers and practitioners, and contributions are welcome from researchers, lecturers, teachers, and users of Environmental mathematics at all levels regarding the unit scope. We are always delighted to receive the support from all stakeholders. Increasing use of technology is being made in the teaching, learning, assessment and presentation of environmental mathematics today, and original and interesting contributions in this rapidly developing area are especially welcome. Mathematical models arising from real situations, the use of computers, digital assistants and software, new teaching aids and techniques are also an important feature. Discussion is encouraged on methods of widening applications throughout science and technology and supporting the community in environmental problems solving.
