The Sahara is built up of a diverse amount of geographic landscapes, comprising mainly of sand dunes, gravel plains, rocky plateaus, and even some mountain ranges, such as the Ahaggar (with peaks rising above 9,500 feet) and Tibesti ranges (containing Mount Emi Koussi, a peak that rises a lofty 11,204 feet). Its iconic sand dunes, particularly in Algeria and Libya, can reach heights of up to 180 meters!

The Sahara Desert spans approximately 9.2 million square kilometers and is in fact the largest hot desert in the world. Located in North Africa, it covers parts of eleven countries, including Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan, Algeria, and Tunisia. This expanse of arid land is characterized by its often harsh climate, with massive temperature swings that can soar above 50 degrees Celsius during the day and plummet below freezing at night.

Human settlement in the Sahara Desert is limited but historically significant. Nomadic tribes, such as the Tuareg and Berbers, have traveled this desert for centuries, passing through it mainly for trade while other groups of people wouldn't dare try (understandably). There are some oases, providing vital water sources, that serve as hubs for small to medium-sized towns and cities, like Ghardaia in Algeria and Timbuktu in Mali, the latter being a UNESCO World Heritage site.
The short answer is yes. But, how do we know this? A number of studies, including one that spanned 93 years by researchers at the University of Maryland, have concluded that the sands of the Sahara have been expanding for some time, primarily southward into the Sahel region. Having grown an estimated 10% since 1920, this is an undeniable fact that continues to be demonstrated year after year, with expansion often at its fastest during the summer months when the already dry desert becomes even more absent of water.
The growth of the Sahara Desert is mainly driven by natural climate variability and human-induced climate change. Naturally, a process called the Atlantic Multidecadal Oscillation (AMO), a periodic climate cycle in the North Atlantic Ocean, significantly influences this expansion by affecting regional rainfall patterns. In the case of the Sahara, during warm phases of the AMO, this region experiences drier conditions, causing the desert landscape to spread.
The Sahara Desert's expansion is causing significant environmental and socio-economic issues. As mentioned, the southward creep of the desert into the Sahel is exacerbating drought conditions, making it difficult for local populations to maintain their agricultural and pastoral livelihoods. The loss of this farmland leads to food insecurity, pushing communities into poverty and increasing competition for resources. This can, and sometimes has, resulted in conflict and displacement as people migrate in search of more habitable areas.
As mentioned before, the Sahara's growth results from the complex interplay between natural cycles and climate change. Tackling this issue requires understanding these drivers and implementing strategies to mitigate their impacts on vulnerable regions. Reducing greenhouse gas emissions and adopting sustainable land management practices are some of the steps we can also take part in to help address the root causes of desertification.
Sarhul, the spring festival, holds significant cultural importance for indigenous tribes such as the Mundas, Oraons, and Santhals. Particularly for the Oraon community, it stands out as the largest spring festival observed during the months of March and April. In their native language, it is referred to as βKhaddi,β symbolizing the symbolic union or marriage of the earth. The significance of the forest flower known as sakhua or Sal is paramount as it symbolizes the cultural importance deeply rooted within the forest ecosystem. Despite their inherent significance, forest flowers often go unnoticed, highlighting the need to acknowledge and appreciate their cultural and ecological value. During this festival, reverence is bestowed upon Dharti Mata, as, the wife of Lord Rama encompassing the celebration of all forms of nature.This festival exemplifies the indigenous tribesβ conviction in the autonomy of their nature-centric worship practices which shows their core value of religion different from brahamnical ideologies. It underscores their deep-rooted gratitude towards nature for the sustenance and resources it provides, showcasing a distinct cultural reverence for their environment and its bounty.
This festival provides a strong sense of identity, particularly for theOraon tribe who predominantly engaged in agriculture, adheres to Sarnaism as its religious belief system which is not Hinduism revering nature as integral to their spirituality, this community celebrates the festival by offering homage to trees and various natural elements.
The new Southern Forest Outlook report on water is designed to inform forest sector decisionmakers and the interested public about observed trends, anticipated futures, and critical issues based on authoritative synthesis and interpretation of existing science, data, and 50-year projections.
The spots on a ladybug aren't only for beautification purposes. They also serve as a warning to predators, thereby protecting the insect from predation.
The bright colors and spots warn would-be predators that the insect is toxic and tastes horrible.
Apart from their colors, another one of the ladybug defenses is the foul-smelling blood they emit. This yellow liquid comes from their leg joints, leaving yellow stains on the surface below. This liquid is toxic to various ladybug predators, protecting these little creatures from harm as predators avoid the seemingly sickly beetle. They also have a third defense mechanism, which is to play dead.
Rococo, style in interior design, the decorative arts, painting, architecture, and sculpture that originated in Paris in the early 18th century but was soon adopted throughout France and later in other countries, principally Germany and Austria. It is characterized by lightness, elegance, and an exuberant use of curving natural forms in ornamentation. The word Rococo is derived from the French word rocaille, which denoted the shell-covered rock work that was used to decorate artificial grottoes.
