The Systematic Destruction Of Argentina’s Forest Biodiversity

Statement of question

What are the implications of global changes in Argentina’s Pampean lowland stream as a result of forest biodiversity destruction?

Introduction

The Pampean plains streams and rivers have in the recent past been characterized by a low rate of water flow because of low waters supply from the surrounding terrains. Other factors that have contributed to the low water flow rates are the benthos, silty sediment, high level of solid suspension, deforestation of the riparian forests and are replaced by low-altitude grasslands and reduced rithron. The environments mainly of aquatic reeds coverage both floating and submerged. The terrain has over the past years transformed gradually as a result of the agricultural activities and urbanization. This has led to a loss of the natural biodiversity including forests. Only a few sites have remained reflecting on the original characteristics of this region (Rowntree, Lewis, Price, & Wyckoff, 2001)

The biological communities variations is as a result of the general global climatic change and human activities that has led to assemblages and populations of macrophytes, invertebrate fauna and algae that have had an effect on the environment. This study aims to describe the main limnologic aspects of streams and rivers located in Buebo Airea Province of Argentina. The found features or characteristics will be used to predict the global changes in this area. For instance, by considering the future scenarios affected by climatic change in this Pampean region, it will be possible to project that increase in rainfall will impact on biological communities.

Discussion

The pressure exerted by human beings on water resources and the climate change effects will probably has an effect on geomorphogical and hydrological conditions in different areas around the globe. The hydrological changes will result to tampering with the functioning and structure of river system. The effect will be shown through the malfunction and loss of the services provided by the ecosystem (Sabater, 2008). The threatening of freshwater systems leads to a high proportion of habitat and species loss compared to marine and terrestrial ecosystems. This threat tends to continue as a result of the flow of contaminated water and reduction of water flow rate due to reservoir construction and irrigation and overfishing (McAllister, et al, 1997).

The liminic bodies do comprise of a significant biotic diversity as compared to the freshwater ecosystems in the earth surface. South America is among the few continents in the world with a large proportion of freshwater and has a large extent of biodiversity and aquatic environments variety. Buenos Aires Province of Argentina has the highest concentration of industrial activities and demographic population. It is also the leading region with intense use of agrochemicals due to animal production and agriculture. This wide range of human activities, there is a huge impact on Pampean streams and rivers because of the contamination of their sources from industrial wastes and sewer affluent. Increased urbanization has also contributed to intense deforestation. Current models predict rainfall and temperature increase in Pampean plains (Hulme & Sheard, 1999). This scenario of climate change calls for the need to study the lakes and streams and their runoff patterns.

Conclusion

The paper has discussed the impact of aquatic communities as a result of global changes in Pampa river systems. The limnological characteristics of the streams in Buenos Aires province are used to predict the future changes in this region.
