Question

which method promotes sustainable land use by integrating various ecosystems?
a. urban farming in small plots
b. agroforestry combining trees and crops
c. monoculture of single crop fields
d. soil depletion from overuse
what does the term \permaculture\ refer to?
a. farming with chemical inputs only
b. simulating ecosystems in agricultural design
c. urban gardening in city areas
d. intensive crop production methods

Explanation:

First Question:

• Option a: Urban farming in small plots focuses on urban areas, not integrating various ecosystems for sustainable land use broadly.
• Option b: Agroforestry combines trees (a forest ecosystem component) and crops (agricultural ecosystem), integrating different ecosystems to promote sustainable land use (e.g., better soil health, biodiversity).
• Option c: Monoculture of single crop fields reduces biodiversity and is not sustainable or integrating ecosystems.
• Option d: Soil depletion from overuse is a problem, not a method to promote sustainable land use.

• Option a: Permaculture does not rely on chemical inputs only; it emphasizes natural, sustainable systems.
• Option b: Permaculture is about designing agricultural systems that mimic natural ecosystems (simulating ecosystems in agricultural design) for sustainability, biodiversity, and self - sufficiency.
• Option c: Permaculture is not limited to urban gardening in city areas; it applies to various land uses.
• Option d: Permaculture is not about intensive crop production methods; it focuses on sustainable, ecosystem - based designs.

Answer:

b. Agroforestry combining trees and crops
