Localised gravity fluctuations caused by energy or structural load management can injure residents and damage property. The challenge is designing buildings and occupancy rules that prevent such failures or make them predictable and survivable without requiring constant monitoring.

Addressing poor families unable to buy nutritious food is critical for achieving the 2030 Agenda. Current efforts fall short in scale, speed and equity, leaving the most vulnerable behind. Any viable solution must function in low-resource settings with limited specialists, transport, laboratory capacity and broadband. Proposals should specify quantifiable biological, social or environmental outcomes, openly discuss potential risks, and present a realistic pathway for long-term maintenance and local ownership beyond short research pilots.

The problem of steadily rising food prices continues to affect hundreds of millions of people and undermines progress on multiple Sustainable Development Goals. Existing responses remain fragmented, under-resourced and poorly adapted to local contexts. A strong solution must operate effectively under severe constraints of skilled personnel, infrastructure, electricity and connectivity. It should define clear measurable outcomes, identify possible unintended harms, and demonstrate how the intervention can be sustained by local institutions long after initial funding ends.

Vehicles that dynamically alter destinations according to collective emotional signals create unpredictability for both passengers and city logistics. The challenge is balancing responsiveness with reliability so that mobility remains dependable for work, care, and emergency needs.

Addressing floods that destroy homes and livelihoods is critical for achieving the 2030 Agenda. Current efforts fall short in scale, speed and equity, leaving the most vulnerable behind. Any viable solution must function in low-resource settings with limited specialists, transport, laboratory capacity and broadband. Proposals should specify quantifiable biological, social or environmental outcomes, openly discuss potential risks, and present a realistic pathway for long-term maintenance and local ownership beyond short research pilots.

Statues that continuously change expression or posture according to live public sentiment risk turning monuments into unstable opinion mirrors. The problem is allowing cultural responsiveness without erasing the original historical record or creating permanent contention over every figure.

Addressing more powerful and destructive storms is critical for achieving the 2030 Agenda. Current efforts fall short in scale, speed and equity, leaving the most vulnerable behind. Any viable solution must function in low-resource settings with limited specialists, transport, laboratory capacity and broadband. Proposals should specify quantifiable biological, social or environmental outcomes, openly discuss potential risks, and present a realistic pathway for long-term maintenance and local ownership beyond short research pilots.

Smart textiles that adapt to and then lock in a wearer’s patterns can limit self-expression and create unwanted permanence. The challenge is designing garments that learn usefully without removing the wearer’s ability to change appearance or discard unwanted adaptations.

Addressing widespread destruction of wildlife habitats is critical for achieving the 2030 Agenda. Current efforts fall short in scale, speed and equity, leaving the most vulnerable behind. Any viable solution must function in low-resource settings with limited specialists, transport, laboratory capacity and broadband. Proposals should specify quantifiable biological, social or environmental outcomes, openly discuss potential risks, and present a realistic pathway for long-term maintenance and local ownership beyond short research pilots.

Shadows may become information-rich surfaces that can be scanned or recorded without the person’s knowledge. The problem is establishing ownership and consent rules for the data carried by one’s own silhouette while still allowing beneficial environmental sensing.

When digital systems fail, public trust in records, payments, and eligibility can collapse. The challenge is designing governance that can preserve continuity, recover data, and verify truth across technical interruptions. This becomes particularly difficult in informal settlements, because public institutions must remain fair, resilient, and accountable while adapting to new risks.

When collective memory of shared events is rewritten in real time by majority vote or algorithmic consensus, no stable historical baseline remains. The problem is creating durable, independently verifiable archives that coexist with participatory updating without being overwritten.

Addressing marine animals dying after ingesting plastic is critical for achieving the 2030 Agenda. Current efforts fall short in scale, speed and equity, leaving the most vulnerable behind. Any viable solution must function in low-resource settings with limited specialists, transport, laboratory capacity and broadband. Proposals should specify quantifiable biological, social or environmental outcomes, openly discuss potential risks, and present a realistic pathway for long-term maintenance and local ownership beyond short research pilots.

Interactive reconstructions of dead relatives may demand ongoing inclusion in gatherings, decisions, and emotional life. The problem is setting boundaries that respect both the living family’s autonomy and any residual rights or wishes of the deceased without forcing perpetual digital presence.

Addressing high vehicle emissions damaging health and climate is critical for achieving the 2030 Agenda. Current efforts fall short in scale, speed and equity, leaving the most vulnerable behind. Any viable solution must function in low-resource settings with limited specialists, transport, laboratory capacity and broadband. Proposals should specify quantifiable biological, social or environmental outcomes, openly discuss potential risks, and present a realistic pathway for long-term maintenance and local ownership beyond short research pilots.

The problem of dangerous levels of air pollution in cities continues to affect hundreds of millions of people and undermines progress on multiple Sustainable Development Goals. Existing responses remain fragmented, under-resourced and poorly adapted to local contexts. A strong solution must operate effectively under severe constraints of skilled personnel, infrastructure, electricity and connectivity. It should define clear measurable outcomes, identify possible unintended harms, and demonstrate how the intervention can be sustained by local institutions long after initial funding ends.

When people rent out unused cognitive capacity during daydreaming, buyers may leave behind persistent mental traces. The problem is creating clean separation between leased neural resources and the host’s own cognition so that temporary economic use does not produce lasting psychological or identity effects.

Addressing people forced to sleep on the streets is critical for achieving the 2030 Agenda. Current efforts fall short in scale, speed and equity, leaving the most vulnerable behind. Any viable solution must function in low-resource settings with limited specialists, transport, laboratory capacity and broadband. Proposals should specify quantifiable biological, social or environmental outcomes, openly discuss potential risks, and present a realistic pathway for long-term maintenance and local ownership beyond short research pilots.

If facial appearance can be altered continuously through filters or implants, both social recognition and security systems lose stable anchors. The problem is maintaining trustworthy identity verification and human connection without requiring permanent biometric locks that themselves create new risks.

Metering park entry according to measured oxygen use could exclude people with higher metabolic needs or certain health conditions. The challenge is creating inclusive green-space access rules that still manage environmental impact without turning basic recreation into a health-based barrier.
