Green Revolution
$135.00
Green Revolution, the great increase in the production of food grains that resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century. Its early dramatic successes were in Mexico and the Indian subcontinent. The new varieties require large amounts of chemical fertilizers and pesticides to produce their high yields, raising concerns about cost and potentially harmful environmental effects. Poor farmers, unable to afford the fertilizers and pesticides, have often reaped even lower yields with these grains than with the older strains, which were better adapted to local conditions and had some resistance to pests and diseases.

History Of Agriculture
$135.00
Agriculture began independently in different parts of the globe and included a diverse range of taxa. At least eleven separate regions of the Old and New World were involved as independent centers of origin. The development of agriculture about 12,000 years ago changed the way humans lived. They switched from nomadic hunter- gatherer lifestyles to permanent settlements and farming.

Introduction To Agroecology: Principles And Practices
$135.00
Agroecology is defined by the OECD as "the study of the relation of agricultural crops and environment." Dalgaard et al. refer to agroecology as the study of the interactions between plants, animals, humans, and the environment within agricultural systems. Francis et al. also use the definition in the same way but thought it should be restricted to growing food.
