Since the weather, insects and diseases threaten the crops throughout the year; this has prompted scientists and farmers to use of fertilizers, pesticides and herbicides to sustain crop production.
Recent studies have shown that this does more harm than good since the ingredients for these products are hazardous to health. This has changed again the approach used by farmers and scientist who want to go back to organic farming.
To control crop production against the weather, greenhouses have been erected. This provides a controlled environment to grow the plants all throughout the year.
