(innovation in agriculture for sustainable future prospects and challenges ) paragraph
plz me

I can give you some ideas:
In developed countries the era where one household could own a small field and make a decent living are over. Agricultural activity needs to be of a certain scale to be profitable and productive.
Educated farmers know how to increase crops output, and may experiment with different variations of crops, different means of keeping pests out and so on. When farm employs specialists, it's output will likely increase in the future, because people who are assigned to certain tasks know what they should do and can keep track of recent innovations in the field.

Recently certain services appeared, which assure farmers that they wont lose more then a certain (small percentage) of their crops due to pests. This company signs a contract with farmer for a fixed price, and specify that for example out of all crops only 5% will be lost due to pests (if a higher percentage is lost, company pays penalty). Companies which do that have know-how to assure that the minimal amount of pesticides will be used (the more pesticides they use, the more bigger costs they have, so it's imperative for them too use as little as possible), which is good for environment, farmer (he pays less for the service, than he would pay if he did it on his own), and for economy (resources are efficiently spent).

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.
