Landmines are considered one of the most horrifying, unethical tactics used in modern wars.
◦ Large minefields is planted with anti-personnel explosives, usually to give a temporary strategic advantage, and get left after wars, ending thousands of innocent civilian lives, and preventing the social and economical development to reach the affected zones.

Egypt considered one of the most affected countries with landmines, with nearly 20% of the total landmines in the world.
◦ "The northwest coast has great development potential; the area is one of the greatest promises for Egypt. But the mines deny access to a landmass of approximately 22 percent of the national territory," El-Shazly* said.

Used in the initial detection phase
Either sharply accurate or precise

Advantages◦ Simplest◦ Cheapest◦ Widely used
Disadvantages◦ Dangerous
◦ Another significant issue concerns the safety of the deminer. For every 5000 mines removed, one deminer is killed.

Had been mainly used in Afghanistan
Less risk on the deminer himself
Generally, the most efficient solution

Special vehicles, that can withstand the explosions
Combine detection & removal in one operation
Sometimes, used as an extra layer of security after another method

Research had been made to make use of the following, for landmine detection as well:
◦ Honey bees
◦ Mammals
◦ Plants
◦ bacteria

Therefore, the Egyptian Government and agencies providing assistance must allow for substantial resources to be devoted to finding better solutions to the mine and UXO clearance problem.

EMI Stands for Electromagnetic Induction
Time-varying magnetic field
Detect most metals
Unacceptable false alarm rate

GPR stands for Ground Penetration Radar
Uses electromagnetic waves
Waves reflected from buried objects
Antennas transmit and receive the waves
Very clean response

Probes the surface with seismic waves
Excite mechanical response of buried objects
Distinction between landmines and other objects is clear from formed images
Very resistant to most types of clutter
