What is Agriculture?

Agriculture is the science and art of growing plants and other crops, and raising animals for food, other human needs, or economic gain.

Negative Impacts of Agriculture on the Environment

Land Transformation: Due to the use of land to yield goods and services. Examples include clearing forests to make way for parks or gardens.
Land Degradation: The long-term decline in ecosystem function and productivity. Examples include soil erosion, soil exhaustion, and soil salinization.

Types of Pesticides

Organophosphates are among the most abundantly used synthetic pesticides.
Chlorinated Hydrocarbons (organochlorines) are highly toxic and persistent to sensitive organisms
Fumigants are small molecular compounds, like ethylene dibromide, methylene bromide, and carbon tetrachloride.
Inorganic Pesticides are compounds made from toxic elements such as copper, sulfur, arsenic, and mercury.
Natural Organic Pesticides (botanicals) are extracts from plants like nicotine from tobacco and pyrethrum from Chrysanthemum.
Microbial Agents and Biological Controls use living organisms or toxins extracted from them as replacements for pesticides.

Impacts of Environment on Agriculture

Global warming
Heavy rainfall and flooding
Acid Rain
Wind Erosion
Landslides

Why Sustainable Agriculture Matters

Contributes to Environmental Conservation by protecting natural resources (soil, water, air) ensuring healthy ecosystems.
Prevents Pollution by minimizing harmful chemicals and promoting organic farming methods, leading to cleaner ecosystems.
Reduces Costs by lowering input costs through reduced reliance on synthetic fertilizers and pesticides, leading to greater economic efficiency.
Keeps Biodiversity by encouraging the preservation of diverse plant and animal species, enhancing ecosystem stability and resilience.
Respects the Environment by emphasizing harmony with nature, promoting ecological balance, and protecting natural habitats
Profits Farmers Economically by focusing on sustainable practices, tapping into niche markets for organic and locally-sourced products, leading to higher profit margins
Preserves Social Equity by supporting fair labor practices and equitable access to resources, fostering community development and social justice.

Drawbacks of Sustainable Agriculture

Limited use of land to produce large quantities of food, mass production is not possible.
Uses more labor and less automation
Shorter shelf life due to faster decomposition
Less fertile lands because of decreased use of fertilizers.
Lower farmer income due to land used sparingly.

Food and Nutrition

Despite dire predictions about food shortages, world food supplies have outpaced population growth for centuries. Poverty is a greater threat to food security than limitations in food supply
Food security occurs at multiple scales.

Conclusion

Sustainable agriculture protects the environment and ensures future food production.
Traditional agriculture causes land degradation, deforestation, and pollution
Pesticides harm wildlife and ecosystems, though useful.
Climate change and environmental issues make farming more challenging
Food insecurity is mainly due to poverty, not food scarcity
Sustainable farming methods can mitigate the crisis, but need support to combat issues of hunger and poverty
