Rattan Lal (born 5 September 1944) is a soil scientist. His work focuses on regenerative agriculture through which soil can help resolve global issues such as climate change, food security and water quality. [1] He is considered a pioneer in soil-centric agricultural management to improve global food security and develop climate-resilient ...
Highly oxidized red soil in Tirunelveli District, India. Red colors often indicate iron accumulation or oxidation in oxygen-rich, well-aerated soils. [4] Iron concentrations caused by redox reactions because of diffusion of iron in crystalline and metermorphic rock, in periodically saturated soils may also present red colors, particularly along root channels or pores.

The Sahel region (brown), proposed Great Green Wall (green), and participating countries (white) Satellite photo of the Sahara The Great Green Wall or Great Green Wall for the Sahara and the Sahel (French: Grande Muraille Verte pour le Sahara et le Sahel; Arabic: السور الأخضر العظيم, romanized: as-Sūr al-ʾAkhḍar al-ʿAẓīm) is a project adopted by the African Union in ...
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [60] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.
The plants and soil provide more green space and insulation on roofs. Green and blue roofs also help reducing city runoff by retaining rainfall providing a potential solution for the stormwater management in highly concentrated urban areas. [64] The social benefit of green roofs is the rooftop agriculture for the residents. [42]
Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
Sempervivum (/ s ɛ m p ə ˈ v aɪ v əm / [1] [2]) is a genus of about 40 species of flowering plants in the family Crassulaceae, commonly known as houseleeks.Other common names include liveforever (the source of the taxonomical designation Sempervivum, literally "always/forever alive") and hen and chicks, a name shared with plants of other genera as well.
