This phase reimagined food production in a future where fossil fuels, metals, fertile soils, and stable climates no longer exist. The system needed to be renewable-powered, closed-loop, modular, and low impact, providing fresh food under extreme resource scarcity.

Research & Insights
Analysis of climate and resource data showed:

• Agriculture drives 70% of freshwater use and 80% of deforestation.

• Yields of crops like maize could fall by up to 24% under 2°C warming.

• Urban farming offers models for space-efficient, closed-loop, renewable-powered systems.

Concept Development
Six concepts explored hydroponics and aeroponics solutions, each evaluated for water efficiency, lifecycle impact, cost, and scalability:

• DIY Hydroponics Starter Kit using recycled materials.

• Water Testing Kit ensuring safe irrigation.

• Hand-Pumped Aeroponics with zero electricity use.

• Mobile Aeroponics Units for urban community gardens.

• Rose Bio-Indicators for natural nutrient monitoring.

• Vermicompost Tea System using worm castings for fertiliser.

Final Design: Vermicompost Tea Hydroponics System
The chosen design is a solar-powered, closed-loop hydroponics system combining vermicomposting with modular growing tanks.

Key features:

• Resource Efficiency: Minimal water and energy use.

• Scalability: From households to urban farms.

• Food Safety: Controlled growing environment.

• Community Focus: Shared use, education, and resilience.

This system delivers sustainable, nutritious food production for a resource-depleted, climate-impacted world.
