Voluminous Agriculture And Agrotechnic

Date: 01-06-2014 09:56

Voluminous agriculture and voluminous agro-technology has no proper origin. But it had jutted out now and then in many places in private congested areas. It never had a proper application though the advantages of it is always just obvious.

Today, the world has many landscape problems and also the supply of water. The lavish agricultural method ... read full abstract ››

Latent Desertification And The Sea Level Rise

Date: 23-03-2014 15:10

Latent desertification is the main cause to the sea level rise. It is also the main cause for the melting of the glaciers and withdrawal of the Ice-age, which in its turn adds to the sea level. The present latent desertification began about one hundred and fifty millenniums ago. It had been very gradual at the beginning and with time had increased the ... read full abstract ››
