Biological Control and Natural Farming: Sustainable Strategies
1. History and Concept of Biological Control
Biological control is a sustainable approach to managing pests and diseases by utilizing natural enemies, microbes, and botanical extracts. It is a cornerstone of natural farming, emphasizing ecological balance over chemical intervention.
Biological control is the intentional use of living organisms—predators, parasites, or pathogens—to suppress pest populations (Gontijo, 2025).
- Early Records: The practice dates back to at least 304 AD in China, where

Natural Farming: A Paradigm Shift
Natural Farming represents a paradigm shift from chemical-intensive agriculture to a method that works in harmony with nature. It is a holistic approach aimed at restoring soil health, increasing biodiversity, and reducing the cost of cultivation for farmers.
1. Introduction to Natural Farming
Natural Farming (often associated with Masanobu Fukuoka and, in India, Subhash Palekar) is a chemical-free alias of traditional Indian agriculture. It relies on the premise that

Legacies and Governance in Modern Africa
Africa isn’t poor because it’s Africa. It’s poor because it carries three destructive legacies (slavery, colonization, and corruption), but the decisive factor today is governance: countries with strong institutions thrive (such as Rwanda and Botswana), while countries without them collapse (such as the DRC and Nigeria).
Slavery: The Structural Shock
- Catastrophic demographic loss: The loss of people in their most productive years halted agricultural innovation.
Natural Resources: Classification, Sustainability, and Impact
Categorizing Natural Resources
Natural resources are categorized based on their use and renewability:
Classification by Use
- Essential Resources: Air, water, and soil, which are crucial for life.
- Material Resources: Wood, coal, and metals used to create products.
- Energy Resources: Solar, wind, and fossil fuels used for generating electricity and powering industries.
Classification by Renewability
- Renewable Resources: Timber, water, and solar energy, which can regenerate over time.
- Non-renewable Resources:

Foundations of Global Agriculture
What is the essential question regarding agriculture? How does agriculture shape and reflect spatial patterns?
Define subsistence agriculture: Agriculture focused on growing enough food to feed oneself and one’s family.
Define commercial agriculture: Agriculture aimed at producing crops for sale in the market.
What is agribusiness? The business sector encompassing farming and farming-related commercial activities.
