This document discusses desertification, which is the process of fertile land turning into desert. Approximately one-third of India's land is dry or arid and increasing annually, with 90% of land in Kutch and Saurashtra affected by desertification. Desertification is caused by factors like semi-arid land influencing human habitation and animal grazing, which reduces land fertility; salty water sweeping onto fertile coastal land; continuous farming without fertilizer or manure use; and soil erosion by wind and streams. Methods to minimize desertification discussed include water conservation through check dams, irrigation, collecting rainwater, and dry land farming of cactus species that require little water.

Identification Of Soil Erosion Prone Zones Using Geomatics Technology In Part...IJERA Editor
Soil erosion is the removal and subsequent loss of soil by the action of water, ice, wind and gravity. Soil erosion is a process that occurs naturally at a slow rate. The average natural geologic rate of soil erosion is approximately 0.2 tons per acre per year. Erosion is the process were by the earth or rock is loosened or dissolved and removed from any part of earth‟s surface. Geological erosion is the rate at which the catchment or land would normally be eroded without any disturbance by human activity. If man alters the natural system by means of various land use practices that is caused accelerated erosion. The present study area is covering Parts of North Arcot The area is lies between E78°30'-E78°45' lattitudes N12°15'-N12°30„. The total aerial extent of the study area is 720 sq.km. It falls in the survey of India Toposheet 58 L11 on 1:50,000 scale. The IRS – 1D satellite imagery data were subjected to different types of image enhancement techniques and soil erosion areas were mapped out and GIS databases were generated showing the soil erosion areas using Arc Map 9.1 version. GIS overlay function was executed between soil erosion prone areas and the various controlling variables and the area has been fragmented into a number of polygons of land segments depending upon the controlling variables. Finally, the remedial measures were suggested for each land segment according to the controlling variables.
A presentation on soil erosion conservation consisting of causes of erosion, need for soil conservation along with various prevention techniques for soil conservation.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
