2.7.2.1. Traditional system

The traditional system is again subdivided into two types namely:

(a) Traditional Subsistence Agriculture (TSA): In this system, only enough crops or livestock are produced for the use of family and a little surplus to sell to meet the needs.

(b) Traditional Intensive Agriculture (TIA): Farmers increase their inputs of human labor, water, fertilizers to get higher yields for the use of their families and to sell small quantities for getting income.

The traditional agricultural system is fundamentally aimed at sustaining families through their farming efforts. It can be categorized into two approaches:

1. Traditional Subsistence Agriculture (TSA): This approach focuses on producing just enough food or livestock to meet the family's needs. Any extra is sold for additional income. This means farmers work hard to ensure they don't produce too much or too little; their survival depends on it.

2. Traditional Intensive Agriculture (TIA): This method goes a step further, where farmers utilize more inputs—like labor, water, and fertilizers—to increase their crop yields. The goal here is to grow more food not just for their families but also to sell for income, enhancing their economic stability.

The two systems illustrate how traditional farming can range from simply meeting the family's needs to actively seeking profits.

Imagine a family living in a small village. In the TSA model, they have a small garden where they grow just enough vegetables and grains to feed themselves and maybe have a few extra tomatoes to sell in the market. On the other hand, consider that same family using the TIA model—they decide to work a little harder, invest more time pulling weeds, and buy some fertilizer. Now they grow enough tomatoes to feed friends and relatives as well as still have a surplus to sell. This extra income helps them buy clothes or school supplies for their children.

In the system of modern and industrialized agriculture, a large extent of land will be brought under agriculture and huge quantities of fuel, energy, water, chemical fertilizers, pesticides used to produce large quantities of single crops purely for sale.

Modern and industrialized agriculture represents a significant shift from traditional methods. Instead of small-scale farming for subsistence, this system focuses on maximizing output. Key features include:

• Large-scale Land Use: A vast area is cultivated to increase the production capacity.
• High Resource Input: This system relies heavily on fuel, energy, and large quantities of water, along with chemical fertilizers and pesticides.
• Monoculture Farming: Farmers generally grow a single type of crop, as opposed to multiple types. This method is efficient for production but can have various environmental impacts, such as depletion of soil nutrients and loss of biodiversity.

Think about how large corporations operate compared to small family-run businesses. A small bakery might make a variety of breads, focusing on quality and local sales. In contrast, a large commercial bakery will automate production to focus on making one type of bread in massive quantities, using machines and chemicals to optimize profits. This is similar to modern agriculture, where efficiency and output often come at the expense of biodiversity and environmental health.

However, this modern agricultural system has its own adverse effects on environment. Excessive use of chemical fertilizers to boost up the crop yield, contaminate groundwater with nitrate.

One major concern about modern agricultural practices is the excessive use of chemical fertilizers. While these fertilizers can significantly increase yield, they pose serious environmental risks. Here’s how:

• Groundwater Contamination: When farmers apply more fertilizers than plants can absorb, the excess is washed away into the soil and can seep into groundwater. Nitrates, a common component of many fertilizers, can contaminate drinking water sources. High levels of nitrates can cause serious health problems, particularly in infants where it can lead to a condition known as 'Blue Baby Syndrome.' This condition affects oxygen transport in the blood.

Therefore, while modern agriculture aims to increase food production, it can have severe, unintended consequences on public health and the environment.

Consider a sponge in a sink. If you pour soapy water (representing fertilizer) onto it, the sponge can only soak up so much before it starts leaking out. Similarly, when too much fertilizer is applied to fields, the excess can seep into water systems, just like the soap water seeps out of an overly saturated sponge.

The excessive N P K fertilizers in agriculture fields are often washed off with water and leads to algal blooming and Eutrophication.

The use of NPK fertilizers (nitrogen, phosphorus, potassium) in agriculture can lead to negative environmental effects, particularly related to water bodies:

• Algal Blooms: When rainwater carries excess nitrates and phosphates from farms into lakes or rivers, it can trigger excessive growth of algae. This phenomenon is known as algal blooming.
• Eutrophication: Over time, such blooms can deplete oxygen in the water, killing fish and other aquatic life. This process is known as eutrophication.

These impacts not only disrupt aquatic ecosystems but can also affect drinking water quality and local economies that depend on healthy fish populations.

Imagine adding too much fertilizer to a fish pond, causing plants (algae) to grow uncontrollably. As these plants grow and die, they consume oxygen that fish need to breathe, potentially leading to fish kills. It's similar to a crowded party where there are too many people (algae) and not enough air (oxygen) for everyone.

Excessive application of chemical fertilizers can increase soil salt content. The percolation of domestic and industrial sewage also increase the salinity of soil.

The long-term application of chemical fertilizers can lead to increased soil salinity, which poses a threat to agricultural productivity. Here’s how:

• Soil Salinization: Regular use of fertilizers can raise the salt levels in the soil. High salinity makes it difficult for plants to absorb water, leading to poor crop health and lower yields.
• Impact from Sewage: Additionally, when domestic and industrial waste is released onto agricultural land, it can contribute to higher salt levels—compounding the salinity problem that affects plant growth and agricultural productivity over time.

Think of salinization as if you're trying to hydrate a plant by pouring saltwater on it instead of clean water. Even though you're giving it water, the salt prevents it from absorbing what it needs to thrive.
