Weather and Environment Impacts in Brazil Essay - 747 Words

Weather and Environment Impacts in Brazil Manaus is a remote town located in a rainforest, so obviously there is a large influence by the weather on the environment around Manaus. Yearly it receives about 84 inches of rainfallinches of rainfall leading to the first environmental impact of the weather: flooding. Manaus is located near the junction of two major rivers, the Rio Negro and the Rio Solimoes, which combine slightly to the east of Manaus to from the Amazon river. The land is relatively flat, and therefore serves as a flood basin for the rivers. The average yearly fall of the river may be around 33 feet (1). The flooding is a risk to humans in that it may threaten the city and homes, but there is also important ecological†¦show more content†¦The flooding in Amazonia may possibly increase in the coming decades if climate change predictions play out as forecasted. There is an expectation that severe weather events will become more common and more intense, something of particular concern to an area which is cl assified as rainforest (Lamb, Somerville, IPCC). Erosion may increase and more land areas used by humans may become inundated. There is the concern that the historical fixes such as the dam may overflow due to the increased detritus and rainfall combinations. A second area that was just mentioned was erosion. Soil is strongly affected by the weather and environment in the Amazon. Because the area receives so much rain it has a history of farming. The problem becomes that any nutrients provided by the rain are usually absorbed immediately by the trees where they remain tied up. Cutting the trees down to allow nutrient build-up in the soil has its own issues. Studies have found that removal of forest affects cloud cover (Durieux Et al. 2003). Convection currents may change resulting in seasons becoming more pronounced. The study noted that this was not theoretical – the changes were already underway in deforested areas (Durieux Et al. 2003). Forest are necessary to combat erosion, and with these more pronounced (and potentially more intense) weather events there is a chance that flood rates, erosion and other factors will be much more intense (Bruijnzeel, 2004).

Projections to the year 2020 indicate the country’s soybean production will increase to 105 million tons, mainly due to Brazil’s large expanse of arable land with potential to be used for agriculture. This expansion of soybean production will occur mainly in the North and Northeast parts of the country (Viana et al., 2013). For example, in the past decade the Para State, Northern Brazil, has seenRead MoreEffects Of Deforestation On The Amazon Rain Forest1196 Words   |  5 Pagesclearing of trees. With the increase of trees being cleared the environment aspects have changed such as the carbon cycle, water cycle, soil moisture, and climate change. The Amazon rain forest has been struggling deforestation for a very long time that it has affected the carbon cycle, water cycle, and most importantly the climate change. The climate change plays an important role not just in the forest but also in the industrial environment. Climate change and the widespread of forest deforestationRead MoreStrategic Asset Allocation Has Proved That It Improves Investors Returns And Reduces Portfolio Risk1406 Words   |  6 Pagesoutlook is not certain either, with the US with a controversial president-elect and UK exiting the EU, we still have a lot to endure. However, if we have to pick a base case, we would choose a rebound in global economy due to countries such as Russia, Brazil and Argentina.

The constant destruction of the rainforests will only destroy the atmosphere, the environment, the life in theses ecosystems, and ultimately the world. Forests help relieve the effects of carbon dioxide and greenhouse gas emissions, on the other hand the effects of deforestation is an increased greenhouse gas emissions that not only impacts the forests but also the ecosystems around in which life resides.

A fragile environment is an area where the flora and fauna have adapted to a specific climate and evolved to occupy many different niches due to extremely high competition for resources. Furthermore due to the constant abiotic conditions, specialisation and symbiotic relationships have occurred to such a degree that even the slightest ecological or environmental disruptionRead MoreChile s Economic Impact On The Philippines Essay1004 Words   |  5 Pagesattributes.
