Not to be confused with remote viewing which finds its home in parapsychology, remote sensing involves collecting data about an object without having any physical contact with the object being observed. There are several types of remote sensing systems used in agriculture but the most common is a passive system that senses the electromagnetic energy reflected from plants. The sun is the most common source of energy for passive systems.

To GM or not to GM remains the Shakespearean conundrum a number of African countries still find themselves in. But is there a way to exploit biotechnology without causing such public unease? Selection with Markers and Advance Reproductive Technology (SMART) breeding could be the answer.

In many households around the world the words “don’t play with your food” quickly followed by “you know there are people out there who…” have been uttered in one form of another. But what if playing with your food could better feed the future? Research scientist Caleb Harper and a team of students at MIT are creating a real-life FarmVille - a food computer. FarmVille is a farming simulation social network game that allows players to plant and harvest crops. Based on these ideas, Caleb has found a way to import climates and make growing food both faster and more efficient.

Did you know that eavesdropping has been going on for centuries? Acoustics – an interdisciplinary science, which includes topics such as vibration, sound, ultrasound and infrasound. Hearing is a crucial means of survival for all species in the animal world - including bugs, which, ironically, are now being bugged. Vibration sensors are monitoring their communication in a bid to hijack their mating calls to develop an acoustic pesticide.

Less than 2 per cent of the Kenya's agriculture is irrigated, largely due to the prohibitive cost of equipment and diesel. This leaves farmers extremely vulnerable to drought and puts the country’s food security at great risk. The Sunflower water pump hits all the right environmental notes - running on clean and renewable energy. It retails at around USD 400 which, in comparison to its diesel-fuelled counterparts - costing roughly USD 2,800 - is a near night and day difference. Furthermore, as there are no fuel costs, the initial investment can be recouped in 1-2 years. As such, Sunflower presents a compelling economic case.
