An agrostologist is someone who studies botany, more specificly, the study of different types of grasses. This study is found to be important to third world countries as well as those of the developed world. In India, there are migratory communities that rely heavily on the country's grasslands. According to an estimate based on the 1991 census, on average, every hectare pastureland has more than 7.88 migratory animals grazing on it. This pressure is expected to further increase, if the rising trend of migratory animal population and the number of sedentary animals is also taken into consideration.
Maintenance of wild and grazed grasslands is of utmost importance to the world for without these grasslands, starvation will become far worse. Agricultural crop plants such as rice, maize, sugarcane and wheat grasses and many types of animal fodder are all types of grasses. Also, urban and environmental horticulture, turfgrass management and sod production, ecology and conservation has become important to the growing needs of the population.
As the ever increasing world population demands more meat, milk, and wool, more pastureland becomes arid. The worse the pastureland becomes, the more trees are felled to create more grazing lands. Take this into consideration along with the increase of noxious weeds that cannot be fed to animals, and there becomes a world crises.
As a result, there is more pressure put on the scientific world to find a solution to the ever increasing need for better grasses, which have the growth potential to overcome the growth of unwanted weeds. It is found that cultivated grasses possess higher biomass production per unit land, high nutritive value, high palatability and very low wastage by the animals as compared to the conventional grasses.
The socio-economic conditions, lifestyle and food habits of people make a collective impact that further encourages an increase in the livestock population. Hence, agrostology is considered to be a highly important option for science and pertinent, to the growing needs of the world population.
