Are you wondering how to start a community garden?
For the rest of the world, China is a country that is big enough to grow food for the whole population and but in reality this statement is not 100% true. China is not capable of making their crops free of contamination. 8 million acres of agricultural land are not fit for growing crops.China is determined to grow a huge amount of crops from its land which put these lands very close to chemical plants and heavy industries hence raising the risks of contamination in the food. Officials revealed toxic metals and banned pesticides in this fields which can contaminate the crop. Rice with high level of cadmium is seen in the market. The chinese government is going to spend millions in this matter.
A new method of extracting maple sap can revolutionize the whole business. Scientist have found out a way to efficiently take maple sap from the trunks of saplings and increase syrup production. The idea behind it is that instead of using big trees in a forest, the new method would use young trees grown in tight rows, like Christmas trees. The Use of young trees also gives syrup makers more opportunity for genetic experiments and they don’t have to wait for the tree to grow also. The saplings will be cut and a vacuum is put into it to take the sap out. The syrup produced from these saplings will be identical in taste and color. The yield also increases in this way.
According to a recent study, crops in high CO2 atmosphere will have less nutrition in them. This a very serious issue for the future. Scientists usually predict that the yields of crops could be raised by higher atmospheric CO2, but its nutritious value will decrease . Samuel Myers of Harvard University has reported that the CO2 levels in coming years will probably reduce the levels of iron, protein, zinc etc in crops like rice, wheat and soybeans. The study found that nutrients changed unequally when CO2 was higher. Another experiment at the Long’s university shows that rising CO2 levels lowers the resistance of crops to pests. Myers suggests there should be a worldwide effort to develop new breeds of crops that show resistance to higher CO2 levels.
A type of short haired bumblebees which was last seen in 1986 in the UK has survived and are flying again thanks to the efforts of farmers and researchers. Researcher Nikki Gammans has found these bees for the first time in more than 25 years in the summer of 2012. These bees are conserved and are now growing in numbers. Despite efforts from Dungeness and Romney Marsh which is a national nature reserve and Site of Special Scientific Interest, the main key to this success is the role of nearby farmers, who have planted acres of wildflowers in order to make sure the bees have an outstanding source of pollen to sustain. The number of bees seen in crop fields are increasing and the environmental stewardship schemes have also helped a lot in this project.
