Globalization of agriculture refers to the growing interdependence of agricultural systems around the world, driven by factors like trade, technology, and the entry of multinational corporations. Let's evaluate the options:
A. Contract farming - Contract farming is an indicator of globalization as it involves global corporations or large companies contracting with local farmers to produce agricultural goods for a global market. This is a direct result of global agricultural integration.
B. Increased dependence of farmers on fertilizers and pesticides - The increased use of fertilizers and pesticides is a common feature in globalized agriculture. However, this is more of a consequence of industrialization and modernization of agriculture rather than a direct indicator of globalization itself. Still, it can be seen as part of the global agricultural practices.
C. Promotion of indigenous knowledge for agriculture - This is not typically an indicator of globalization. In fact, globalization tends to promote modern agricultural practices and technologies rather than indigenous knowledge. While there is some interest in preserving traditional methods, they are not as widespread in the globalized agricultural system.
D. Entry of multinationals into agricultural sector - The entry of multinational corporations into the agricultural sector is a clear and strong indicator of globalization. These companies play a significant role in shaping global agricultural policies, market structures, and practices.
Thus, the indicators of globalization of agriculture are Contract farming, Increased dependence of farmers on fertilizers and pesticides, and the Entry of multinationals into the agricultural sector.
Therefore, the correct answer is Option 2: (A), (B), and (D) only.
