Aquaculture: Farming Aquatic Organisms

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs, algae, and other aquatic plants. Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Farming implies some sort of intervention in the rearing process to enhance production, such as:

• Regular stocking
• Feeding
• Protection from predators

Particular Kinds of Aquaculture

Fish Farming (Pisciculture)

Fish farming or pisciculture involves the commercial breeding of fish, usually for food, in fish tanks or artificial enclosures such as fish ponds.... Continue reading "Aquaculture, Biology, and Agriculture: Core Concepts & Practices" »

Key Milestones in Sustainable Development

The Club of Rome (1968)

• Created by scientists, economists, businessmen, and civil servants concerned about the way modern societies were developing their economies.
• "The Limits to Growth" (1972, MIT, Massachusetts Institute of Technology): This projection for the next 100 years makes clear that our economic model is not sustainable, primarily due to resource depletion and pollution.

First Earth Summit (1972)

As the UN wanted to address environmental problems, they created the Brundtland Commission, which published "Our Common Future" (1987). This report defined "sustainable development" as development that "meets the needs of the present without compromising the ability of future generations to meet their...

Indigo Cultivation: Nij and Ryoti Systems

There were two main systems of indigo cultivation: Nij and Ryoti.

The Nij System of Cultivation

• In the Nij system of cultivation, the planter produced indigo on lands that he directly controlled.
• He either purchased the land or leased it from other zamindars, producing indigo by directly employing hired laborers.
• Planters found it difficult to expand the area under Nij cultivation, as they required large areas in compact blocks to cultivate indigo in plantations.
• The planters also found it very difficult to mobilize labor. Labor was needed precisely at a time when peasants were usually busy with their rice cultivation.

The Ryoti System of Cultivation

• Under the Ryoti system, the planters forced the ryots to

Modified Urban Plan Characteristics

• Increased land value
• Increased number of floors
• Standardized blocks (100x100m or 125x125m)
• Wide "Rondas" (50m wide)

The Linear City Concept

Context and Origin

The Linear City was a proposal by Arturo Soria y Mata, a Spanish engineer, architect, and urban planner. He presented his project in 1882, with development commencing in 1894.

Concept and Design

Soria's project proposed an elongated city extending along a main transportation route, with a constant width, creating a linear structure instead of the traditional radial or concentric forms. The linear city was planned to extend approximately 48 km and be about 500 meters in width. An electric tram was proposed to run the entire length of the city.

Understanding Biodiversity

Biodiversity—short for biological diversity—is the variety of all living organisms on Earth, including their genetic differences and the complex communities (ecosystems) they form. It is the biological safety net that keeps our planet functional.

1. Levels of Biodiversity

Biodiversity is studied at three distinct, interconnected levels:

• Genetic Diversity: The variation in genes within a single species. This variation allows a population to adapt to changing environments, diseases, and climates. Example: India has over 50,000 distinct strains of rice and thousands of mango varieties.
• Species Diversity: The variety and number of different species within a specific region. Example: A tropical rainforest has vastly higher

1. Urban Planning Fundamentals

• Neighborhood Design:
  • Emphasis on mixed-use developments combining residential, commercial, and green areas.
  • Centralities such as cultural facilities, educational buildings, and healthcare centers are located near main streets for accessibility.
• Sustainable Mobility:
  • Priority on pedestrian-friendly streets and reduced car impact near green areas.
  • Speed bumps and reduced speed limits (30 km/h) enhance safety and promote cycling.

2. Street Hierarchy and Design

• Main Streets: Connect neighborhoods to highways and key points, often two-way streets.
• Secondary Streets: Support local traffic, with some designed for coexistence (shared pedestrian and vehicle spaces).
• Tertiary Streets: Local streets connecting smaller blocks, some

Hook

Hook: From the towering spires of Manhattan to the vibrant streets of Brooklyn, New York City embodies the energy and diversity of the world itself.

Context

Context: New York City has been the country's largest city since 1970. The center of the New York metropolitan area is one of the most populous agglomerations in the world. It is located on the eastern Atlantic coast of the country.

Definition: Global City Meaning

Def: One of the main global cities, which signifies that it is a city that serves as a primary node in the global economic network with: large population, multinational companies, globalized financial sectors, international transportation, high-quality research systems, and a world cultural output.

Early Workers' Movements and Social Change

First Movements Against Working-Class Exploitation

• Luddites (1811): Destruction of machines as a form of protest.
• Workers' Associations (Early 19th Century): Provided aid in cases of unemployment and illness; demanded better working conditions.
• Trade Associations (1834): Demanded the right to unionize, higher wages, shorter workdays, and child labor legislation.
• Chartist Movement (1834-1848): Advocated for universal male suffrage, empowering workers to influence laws.
• Utopian Socialists (First Half of 19th Century): Sought to transform capitalist society through collectively owned communes.

Political Ideologies: Marxism and Anarchism

Marxism

• Based on historical materialism.
• Supports political parties as a means
