DROUGHT ADAPTATIONS IN KENYA INTRODUCTION The Lancet commission on Health and Climate change June 2015 list four direct effect of climate change; ’Increase heat stress, floods, drought and increased frequency of intense storms”( The Lancet, 2015). Who. int (2015) describes drought as a period in the climate cycle caused by lack of rainfall that result in lack of water that then leads to food shortages. The populations mostly affected by this climate induced disaster are; people of low social…

gases. “Soil biological processes have major long-term effects on composition of Earth’s atmosphere, which in turn influences all living things, including soil microorganisms” ( Brady, Weil 2008). Changes in atmospheric concentrations of carbon dioxide, temperature, and precipitation amounts and patterns will modify the soil plant system, and influence decomposition rates which will have impacts…

Within recent decades, there has been an experience in the decrease of the soil health and fertility around the world. There are many causes to this, which will be explained later on into this essay. This is a problem that needs to have more focus put on it because soil health and fertility is arguably the basis for all of our foods and without having healthy and fertile soil, there will be a decrease in the amount of crops produced. But not only is the amount of crops produced affected, the…

early civilizations in India, South America, Japan, and china practiced intensive agriculture and it is known that they utilized agricultural, animal and human residue as fertilizer (Howard, 1943, Food and Agriculture Organization, 1978). Many of these residues either were placed in pits or placed in heaps and allowed to rot for long period of time for the production of soil amendment. The first waste pits made out of stone and built outside the houses were found in Sumerian cities about 6000…

Plant Science - Seed germination and growth The research question: What is the effect of changing the pH of the soil on the germination and growth of mustard peas? Hypothesis: The greatest number of peas will germinate and will grow the most when the pH is 5 or 7. Theory: Enzymes play a vital role in the cells of plants (especially when growing) and enzymes work best when at their optimum pH value. Moreover, all chemical reactions have an optimum pH at which they work best (Howard and…

more engaging and personalized approach. Also, do your research in advance because that keeps the designing of your home fun. You do not encounter undesirable surprise that arise later down the road. What research does G.J. Gardner Homes recommend? Soil…

Soil preference of the Red Compost Worms, Eisenia fetida INTRODUCTION Earthworms provide countless benefits to humans, plants and animals, by improving drainage, advancing nutrient accessibility, and providing a steady soil system, helping to develop farm production. They benefit the soil ecosystem by decomposing and recycling organic matter, opening up pores inside the soil to develop its formation and supplying food for predators . By adding nutrients to the soil they inhabit, earthworms are…

He also adds on by stating that “Garden beds improve growing conditions for plants by lifting their roots above the soil”. Providing us with a simple but key explanation of why plants seem to grow faster if planted in garden beds. Hayes says that, “The soil in beds that are raised warms up earlier in the spring and is innovated by certain grasses and by the tree roots”. Recommending several steps to construct a raised garden bed. First…

Paragraph IIA Thesis: Instead of putting restricted rules on growing hemp, government should legalize the planting of hemp due to its valuable content and it is people’s basic freedom. Instead of restricting the production of hemp, the United States government should legalize the planting of hemp due to its beneficial value to society while fulfilling the natural rights and freedom of America. Hemp planting is currently considered illegal, but due to its value in different field and people’s…

Nowadays, urban growth has become a big treat to the environment. The transportation and the construction of facilities have introduced different kinds of invasive species in Seattle. Moreover, the illegal waste dumping and lack of maintenance also help spreading the invasive species. The common invasive species in Seattle are English Ivy, Himalaya Blackberry, American Bull Frog and fox squirrel, etc. The invasive species usually compete and edge out the native species. After a period of time, a…
