Course Overview:

Welcome To EarthTab Business School. My Name Is Andile Dlamini And I Will Be Your Course Preceptor For The Course, Biotechnology In Agriculture.

Agriculture has been the backbone of human civilization for over 10,000 years, providing food, fiber, and raw materials for survival and development. However, with the exponential rise in population, climate change, diminishing natural resources, emerging pests and diseases, and declining soil fertility, traditional agricultural methods are no longer sufficient to meet global food demand. This challenge has given rise to biotechnology in agriculture; a revolutionary integration of biology, genetics, microbiology, molecular sciences, and agricultural practices that aims to optimize productivity, enhance crop and livestock quality, and ensure sustainability in food systems.

Biotechnology in agriculture leverages molecular tools, genetic engineering, tissue culture, genomics, proteomics, metabolomics, bioinformatics, and microbial innovations to solve agricultural problems. It focuses on creating high-yielding, stress-resistant, pest-resistant, nutritionally enhanced, and climate-smart crops and livestock, while also reducing the environmental footprint of farming.

This course will provide an in-depth exploration of agricultural biotechnology, equipping you with both theoretical insights and practical applications in plant and animal sciences, soil fertility management, pest and disease control, post-harvest technology, and sustainable farming systems.
