The problem of multi-year funding remaining rare 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.

The problem of phones dying after two years 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.

Addressing justice delayed for years 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 languages dying every year 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.

asylum processes that take years remains one of the most urgent challenges of our time. Systems currently in place are inadequate for the scale and complexity of the problem. A successful approach must work where resources are scarcest and demonstrate clear, measurable results. It should identify possible harms, respect local agency, and show how the solution can be maintained and expanded by the communities it is meant to serve.

Addressing court cases taking years to resolve 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 lakes shrinking year after year 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.

Once login credentials are leaked in a breach, they often remain accessible and exploitable for attackers on illicit marketplaces for years afterward, long after the original breach was reported. Meaningfully reducing this lingering exposure remains unresolved.

Many connected devices become permanently vulnerable once their manufacturer stops issuing security updates, yet the devices often remain in active use for years afterward. A sustainable way to keep abandoned devices secure remains unresolved.

Some of the internet's most widely used open-source components are maintained by very few volunteers, and serious vulnerabilities have been found lurking undetected for years in code millions of systems depend on. Better resourcing and review processes for open-source security remain inconsistently funded.

Cybersecurity threats evolve quickly, but training programs for both professionals and everyday users often lag years behind the tactics attackers are actually using. Closing this education gap remains an ongoing structural challenge.

Many users experience nausea, eye strain, or disorientation after even moderate use of virtual reality headsets, a problem that hasn't been fully solved despite years of hardware improvements. This limits how widely VR can be adopted for work or daily use.

Over the next 10–20 years, biosensors will track vital signs, metabolites, and behaviours, but analytics and integration into care will lag. Edge-computing and clinically validated algorithms will be needed.

South American economies grow around 2% per year on average, below global trends, making poverty reduction and fiscal sustainability difficult. Scenario-modelling tools and inclusive industrial-policy platforms can help governments design more resilient growth strategies.

Resonances and perturbations can destabilize orbits over billions of years. N-body simulations and long-term observation campaigns can test stability.

Conflict and displacement disrupt education pathways. Portable learning records and camp-based schools can maintain continuity.

Vehicle emissions, crop burning, and industrial smoke create hazardous smog seasons in cities like Delhi and Jakarta. Low-cost air-purification tech and stricter enforceable emission-trading systems are needed.

Depression and anxiety are widely underreported due to social taboos, leaving many untreated for years. Anonymous digital counseling platforms tailored to local languages could lower the barrier to seeking help.

Out-of-pocket medical expenses remain extremely high in countries without universal coverage, forcing families to sell assets during health crises. Affordable micro-health-insurance products could reduce this financial shock.

Poor drainage infrastructure and unplanned urban growth in flood-prone areas worsen the damage each year. Predictive flood-modeling tools and resilient housing design could reduce displacement.
