Industrial Agriculture and the Loss of Biodiversity

Preserving Diversity By Way Of Old Crop Varieties

Traditional methods is indeed the most advantageous way to retain sustainable success in farming suggested by Stephen B. Brush in his research of the effect of diversity in agriculture. In "Genetic Diversity And Conservation In Traditional Farming Systems," he explains how analyzing genetic erosion and the loss of genetic resources eventually leads to environmental degradation. Various factors have led to nations turning to improved adoption varieties, primarily the Green Revolution and commercial markets. Brush explores the effects that the Green Revolution has had on resources and agriculture, and explains why nations are

Brush concludes that with the loss of diversity, and the use of adoptive varieties, an enduring subsistence can not be achieved.

Brush provides support for his argument from his research of two indigenous societies that rely on agriculture for subsistence and for standing in the economic market. The potato in the Andes and Rice in Southeast Asia are two products that have proven that ancestral landraces are essential to preventing genetic erosion which bring about crop failure. This is important because these products are necessary for the survival of these people. In both cultures, these foods are fundamental because of their productivity and cultural significance. Crops play a cultural role in many of these societies, in which the destruction of diversity can put peoples, culture in jeopardy. Nazarea shows support for this idea in his work Cultural Memory and Biodiversity. In a field study in the Philippines, he learned the beliefs and practices that the people use when determining the diversity of their sweet potato crops (Nazarea 60).

Agriculture is changing because farmers are changing their systems. Why are these farmers modifying their systems when traditional methods have worked for so many years? Mainly changes such as population growth, migration and pressure for commercialization from outsiders have brought about the need for modern varieties (Nazarea 33). In Andean agriculture, potatoes are
