Land Use Science in Action

ACTIONS AT DIFFERENT LEVELS ARE NEEDED TO MAKE AQUACULTURE MEET THE SUSTAINABLE DEVELOPMENT GOALS AND ADAPT TO CLIMATE CHAGNES

Aquaculture farming has expanded from coastal areas to near-coastal brackish-water and inland freshwater areas, and they widely adopts intensive farming technologies for higher yield.
These cause issues such as increased soil salinization, water consumption and methane emission.
Satellite remote sensing can provide unique and comprehensive mapping of aquaculture, including aquaculture-related landcover/use changes and aquaculture farming activities.
Combined with technical and social surveys, the patterns of aquaculture changes can be revealed.
Stronger actions at the national, regional, and farm levels are needed to regulate aquaculture intensification and expansion to meet the sustainable development goals (SDGs) and adapt to climate changes.

BUILDING ON SUSTAINABLE DEVELOPMENT GOAL INDICATOR 11.3.1. FOR IMPROVED UTILITY AND GUIDANCE

Urbanization is a leading cause of LCLUC globally, although Africa is currently leading these trends, particularly within small to medium sized, or secondary, cities.
UN Sustainable Development Goals (SDG) may contribute to global monitoring of urbanization, but methodological gaps limit the consistent application of SDG Indicators.
We combined remotes sensing products with open-source software to develop automated approaches for delineating urban areas across broad extents and consistently through time.
Urbanization-driven LCLUC hotspots were identified and further analyzed across Ethiopia, Nigeria, and South Africa.

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.

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.

CRUCIAL ECOSYSTEM SERVICE FOR CLIMATE CHANGE ADAPTATION AT THE SAME TIME.

Tree-based sinks are the only actions that remove excess carbon now.
TOF at the scale of individual trees underpin livelihoods of billions of people and lead to more stable incomes under climate-stress conditions.
NASA earth observations make individual tree carbon measurement counting part of Nature-Based Climate Solutions (NBS); this project mapped every tree in Africa.
TOF NBS support most international programs, and White House U.S. Net Zero goals.
Large capital investments are being made in NBS, and TOF solutions increase the relevancy and effectiveness for people’s well being and poverty alleviation.
