Utilizing NASA Earth Observations to Delineate Riparian Corridors and Evaluate Invasive Species Cover in the Verde River Watershed

Riparian corridors in the semiarid Colorado River Basin act as an interface between terrestrial and aquatic systems, play an important role in maintaining biodiversity and wildlife habitat, and contribute to controlling erosion and buffering pollutant and nutrient runoff. However, the proliferation of invasive species...

A turbidity algorithm was applied to visualize plume and estuary conditions in Landsat 8 OLI imagery taken on 01/23/2021 for the Russian River bar-built estuary, California. In areas of water, light orange indicates high turbidity and dark violet indicates low turbidity. Land is displayed with a true color band combination. Turbid waters can indicate poor water quality, as these conditions reduce the amount of sunlight available for photosynthesis in phytoplankton and algae that live in the water. As such, the visualization of turbidity informs conservation agencies on estuary conditions. Image created by Karina Alvarez, Rachel Darling, and Alexander Gunnerson.  Keywords: turbidity, water

Estuaries are dynamic environments that provide a host of vital ecosystem services. California’s Marine Life Protection Act protects such ecosystems by creating Marine Protected Areas. California has approximately 440,000 acres of estuarine habitats as well as 23 Estuarine Marine Protected...

Utilizing NASA Earth Observations to Detect Changes in Nighttime Sky Brightness in Grand Teton National Park

Light pollution causes measurable damage to natural wildlife behaviors and human health, as well as decreases the ability for humans to view the night sky. The artificial brightening of the night sky, or sky glow, created by light pollution subjects nearly 100% of Americans...

Utilizing NASA Earth Observations to Determine Drought Dieback and Insect-related Damage in the Santa Monica Mountains, California

The Santa Monica Mountains (SMM) lie between the city of Los Angeles and the San Fernando Valley, California, enduring as a steadfast haven for native vegetation, wildlife, and recreational activities. Both public and private conservation agencies have secured protection for much of the mountain range...

Utilizing NASA Earth Observations to Develop a Forest Change Detection Tool for Land Conservation in Honduras

The Instituto de Conservación Forestal (ICF) in Honduras is in charge of managing and conserving millions of acres of public and privately-owned forest, including the pristine Río Plàtano Biosphere Reserve. Although one of ICF's main goals is forest conservation, illegal deforestation in Río Plàtano accounts...

AUtilizing NASA Earth Observations to Develop a Land Use Change Detection Tool for Habitat Conservation Plan Areas

Habitat Conservation Plans (HCPs) were designed to protect and manage areas where desired economic development is in conflict with the needs of threatened and endangered species. Each plan is developed through collaboration between United States Fish and Wildlife Service (USFWS) and a landowner or other...

Soil moisture values in Illinois, USA, are displayed in each grid cell through processed SMAP L-Band Surface and Root Zone Moisture Level 4 data. Each segment of the state outline (top to bottom) represents daily soil moisture averages collected on a quarterly interval in 2020. Red values indicate low soil moisture, while blue values indicate high soil moisture. Low soil moisture can inform periods of drought, an important consideration for water resource budgeting.  Keywords: SMAP L-Band, soil moisture, NOAA, Illinois Climate Network, ESRI, Joshua Green, Julia Marturano, Emma Myrick, Kyle Pecsok, Victor Schultz

Drought and flooding in Illinois have severe impacts on the communities and ecosystems of the state. Soil moisture is a valuable indicator of drought and flood vulnerability but can be difficult to measure since in situ monitoring is limited to...

Vegetation Condition Index (VCI) was calculated using 2018 NDVI data from EMODIS. NDVI data was then converted to VCI through a time series and then the image was  later processed. Central Kenya is displayed, red indicates less healthy vegetation (high vegetation stress) and blue indicates healthier vegetation (lower stress). Areas showing less healthy vegetation informs drought management for Kenyan officials to issue drought warnings to affected counties.  Keywords: NDVI, Kenya, VCI, NDMA, EMODIS

Twenty-three counties in Kenya experience frequent drought, which damages agricultural productivity and threatens the health and wellbeing of millions. NASA DEVELOP partnered with NASA SERVIR, the Regional Centre for Mapping of Resources for Development (RCMRD) and Kenya’s National Drought Management...
