Spatial Extent of Thermal Hotspots and Fire Activity in and around Lesotho

-

 Active fire events and thermal hotspots are shown in this instant app. They are produced from VIIRS satellite sensors. The Visible Infrared Imaging Radiometer Suite (VIIRS) is a sensor aboard various Earth-observing satellites, including the Suomi National Polar-orbiting Partnership (Suomi NPP) and the Joint Polar Satellite System (JPSS) series. VIIRS is designed to observe a wide range of environmental phenomena, including thermal hotspots and fire activity on Earth. VIIRS can detect thermal hotspots and fire activity both during the day and at night owing to its ability to measure thermal emissions. This is particularly useful for monitoring wildfires that may continue to burn after the sun has set.

These hotspots focus on the region in and around Lesotho. This app will help you identify fire activities, their radiative power(a measure of the energy released by a fire that can be used to estimate the fire's intensity), locations, and time of occurrence. With this app, managers and natural resource practitioners can identify areas for prioritizing fire management in Lesotho. Also, by using this app, researchers and authorities in Lesotho can track the spread of wildfires, assess their impact on the environment, and make informed decisions regarding firefighting efforts and evacuation measures where necessary. VIIRS is an important tool in the effort to monitor and manage wildfires and other thermal hotspots on Earth. In this app, protected areas data has been incorporated. To use this app you can follow this link: Fire Activity App. while using the app, you can click on the Legend and Filter By Extent to get a chart showing statistics for a region of interest while zooming In. You can also visualize thermal hotspots by time of occurrence which is either night(N) or daytime(D).

THEMEDA TRIANDRA APP FOR LESOTHO

-
Here is some information about Themeda triandra, commonly known as kangaroo grass: Description: A perennial, tufted grass that can grow up to 1. 5 meters tall. Leaves are narrow and green, turning orange-brown in summer. Flowers are red-brown spikelets that appear in branched stems in summer. Found in Africa, Australia, Asia, and the Pacific Islands. Habitat: Grows in grasslands, woodlands, and other open areas. Prefers well-drained, sandy soils. Tolerant of drought and fire. Uses: Important forage grass for livestock and wildlife. Used for erosion control and revegetation projects. Ornamental grass used in landscaping. Interesting facts: The name "kangaroo grass" comes from the fact that kangaroos eat it. The long awns on the spikelets help to disperse the seeds. Themeda triandra is an indicator species for healthy grasslands. Here's a summary of the Themeda Shiny app: Purpose: Visualizes data on Themeda triandra species (red grass) ...

MyLINONYANA: WEB APP FOR BIRDS DATA VISUALIZATION IN LESOTHO

-
This MyLINONYANA App is a web-based app developed in Lesotho using the R Shiny framework. Shiny apps are interactive web applications that are built with the R programming language. The shiny framework is ideal for creating a wide variety of dynamic documents, interactive applications such as decision data dashboards, interactive visualizations, and machine learning models. With the advancements in technology and data analysis tools, it has become easier than ever to explore and visualize bird data. One such tool is the R web app, which allows users to create interactive graphs and visualizations based on bird data. By using the R web app for bird data visualizations, birdwatching enthusiasts can gain valuable insights into various aspects of avian behavior and population trends. They can analyze migration patterns, track species diversity over time, and even study the impact of environmental factors on bird populations. The interactive graphs generated by the R web app enable users to...

Distribution of World`s Mangrove Species along Ocean Currents Gradients

-
Mangrove species are various types of salt-tolerant plant species (trees or shrubs) that occur in intertidal zones of tropical and subtropical sheltered coastlines. The term is applied to both the individual plant and the broader ecosystem. Use the following link to view the global distribution of mangrove species along major ocean currents:  Mangrove Species . In this web app, you can view major ocean currents and a number of mangrove species in either cold or hot currents.
