Biodiversity, a contraction of “biological diversity,” generally refers to the variety and variability of life on Earth. One of the most widely used definitions defines it in terms of the variability within species, between species, and between ecosystems. It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation (number of species) within an area, biome, or planet. Terrestrial biodiversity tends to be greater near the equator, which seems to be the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth. It is richest in the tropics. Marine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future. The number and variety of plants, animals and other organisms that exist is known as biodiversity. It is an essential component of nature and it ensures the survival of human species by providing food, fuel, shelter, medicines and other resources to mankind. The richness of biodiversity depends on the climatic conditions and area of the region.
by Ananna Ahmed and Sonjita Kirtuniya In the advancement of agro-ecology, farmer-to-farmer knowledge sharing is a linchpin for progress. This exchange of insights and experiences among farmers serves as a catalyst for enhancing farming practices and bolstering community resilience. Through such initiatives, farmers gain invaluable exposure to new technologies, innovative techniques, and best practices, ultimately […]
Soil is our lifeline. It sustains life with a variety of foods, holds and filters water to provide us with clean and safe potable water and maintains ecological balance by storing carbon. But there is so much to understand about soil and how it works. Agroecology is a holistic approach to agriculture that emphasises the […]
