Land Use Science in Action

Smallholder agriculture productivity must increase in Ethiopia to meet the demands of a growing population to avert food insecurity

CONTINUED FOREST PROTECTION MUST BE CORE TO COMMUNITY DEVELOPMENT

• Marginal lands are now being used for crop production to feed an ever-growing population.
• Agriculture productivity must increase to meet demand, intensification rather than intensification.
• Currently, an urgent need exists for information to maximize yield based on land capabilities to mitigate land degradation, improve productivity, and to alleviate food insecurity.
• NASA's role in Earth observation is essential for merging cutting-edge modeling with very high-resolution commercial data to inform the sustainability of current land use and food security.
• Long-term effects of a lack of land tenure rights can be addressed with multi-resolution remote sensing data to relieve land pressure and move toward sustainable management practices.

Village Sustainable Planning and its influence on tropical forestry outcomes in Guyana

CONTINUED FOREST PROTECTION MUST BE CORE TO COMMUNITY DEVELOPMENT

• Carbon payment mechanisms to incentive sustainable forest management have an impact on forest loss
• Analyses integrating remote sensing and socioeconomic data can quantify the effectiveness of Village Sustainability Planning program on forest and land use
• With the rise carbon payment mechanisms for forest conservation, urgent need for such analyses is needed to inform current and future sustainable planning
• NASA’s role in Earth observation is essential for measuring and monitoring global investments in carbon markets

Assessing the impact of urban land conversion on local and regional surface climate and its socio-economic consequence

Task 4: Analyzing the building energy demand response and corresponding implications for the wider energy system.

• Urban heat islands (UHIs) in growing cities can have varying degrees of impacts on human health, as well as energy demands for cooling.
• Remote sensing and modeling provide essential information for comprehending and managing urbanization's climate and societal impacts.
• By combining gridded data for temperature, building characteristics, population, and behaviour we are able to model the building energy demand response to UHI
• This demand response can then be used to calculate corresponding changes in power supply and related parameters such as emissions.

Analyzing the Land-Use Change Impacts of Oil and Gas Exploration Related Infrastructure Changes on Arctic Communities

Remote sensing based mixture modeling to study land and permafrost disturbances

• Rapidly changing environmental conditions in the Arctic, driven by amplified global warming, are impacting communities and ecosystems, particularly due to added anthropogenic impacts from energy exploration and development.
• Analysis integrating remote sensing and socioeconomic data can quantify the land disturbances and help understand societal vulnerabilities of Arctic communities.
• Critical need to quantify impacts resulting from expanding drilling in the region.
• Changes to the Arctic ecosystem provide crucial links to the global climate and biogeochemical cycles.

The global wildland-urban interface

A systematic assessment of global areas of potential direct human-environmental conflict

• The wildland-urban interface (WUI) is where houses and wildland vegetation meet.
• The WUI is an area of human-environmental conflict such as wildfire.
• Our new analysis mapped the WUI globally at 10-m resolution from satellite data.
• The WUI covers 4.7% of the global land and is home to half the global population.
• WUI hotspots on all continents in including the US, Eastern Africa, and South-East Asia.
