To reduce water runoff and soil erosion. Step-like levels slow water flow on slopes.

Provide habitat and reduce wind erosion. Linear vegetation creates wildlife corridors and windbreaks.

Maintaining fish populations at healthy levels. Harvest rates stay within the species' natural reproduction capacity.

Farming that meets current needs without compromising future generations. Balances current food production with long-term environmental health.

Contour plowing. Follows natural land contours to reduce water runoff and soil loss.

They naturally enrich soil with nitrogen. Legumes convert atmospheric nitrogen into plant-available forms.

To prevent overgrazing and promote pasture health. Moving animals prevents grass damage and allows regrowth.

The practice of alternating the crops grown on a piece of land. Prevents soil depletion and breaks pest cycles by varying crops.

Composting. Decomposed organic matter adds nutrients and improves soil structure.

Organic farming. Eliminates artificial chemicals in favor of natural processes.

Biological control. Uses natural predators or parasites to control harmful pests.

Use of GPS technology. Precise positioning enables targeted application of inputs.

Efficient water use. Delivers water directly to roots, minimizing waste and evaporation.

Balancing productivity with environmental impact. Must feed growing populations while protecting natural resources.

Mulching. Organic cover reduces evaporation and maintains soil moisture.

A pest control strategy using a combination of methods. Combines biological, cultural, and chemical methods to minimize pesticide use.

Increased susceptibility to pests. Single crops lack genetic diversity to resist diseases and pests.

Planting flower strips. Provides nectar and pollen sources for bees and other pollinators.

Plowing along the contours of the land to reduce erosion. Follows natural slope patterns to prevent water from washing away soil.

Reduces carbon footprint. Solar and wind power decrease fossil fuel dependence.

To maintain productivity while conserving resources. Ensures food security while protecting environmental resources long-term.

Excessive irrigation and poor drainage. Water accumulates salts when it cannot drain properly.

Reduced chemical residue. Living organisms break down naturally, leaving fewer toxic substances.

Preserves soil structure. Minimal soil disturbance maintains beneficial microorganisms.

Integrating trees and shrubs into crop and livestock systems. Trees provide shade, windbreaks, and additional income sources.

Soil testing. Determines nutrient needs and contamination levels in soil.

Ability to withstand and recover from disturbances. Systems maintain function despite environmental stresses or shocks.

Promotes ecosystem stability and resilience. Diverse species create natural pest control and soil health.

Nitrogen. Decomposing plant matter releases nitrogen for crop uptake.
