Soil Quality Assessment in Response to Water Erosion and Mining Activity

The escalating trend of land degradation poses a significant challenge, especially in sloping agricultural terrains, driven by the increasing global demand for food and the limited availability of flat arable land. In response to these challenges, farmers are compelled to shift their focus towards cultivating sloping terrains. This research aimed to employ a comprehensive methodology that integrates on-site field surveys, meticulous laboratory soil analyses, and geospatial data for mapping soil erodibility. The parameters under scrutiny encompass various crucial aspects, including soil texture (ranging from coarse sand to very fine sand, silt, and clay), soil structure, organic matter content, and permeability. The meticulous examination of these factors serves as the foundation for calculating soil erodibility, utilizing the well-established Wischmeir and Smith formula developed in 1978. The research findings present a nuanced understanding of soil erodibility in the study location, revealing a spectrum spanning low to very high erodibility. Specific units, such as Unit 1, Unit 2, Unit 3, Unit 7, Unit 9, Unit 10, Unit 13, and Unit 16, exhibit very low to low erodibility. In contrast, Unit 4, Unit 6, Unit 14, and Unit 15 showcase moderate erodibility, while units like Unit 5, Unit 8, Unit 11, Unit 12, Unit 17, and Unit 18 are characterized by moderately high to very high erodibility. These insightful results shed light on the diverse erodibility levels within the studied locations and provide valuable guidance for formulating sustainable land management practices.

The impacts of climate change on agriculture can have repercussions on global food security. Losses in agricultural yield can lead to food shortages and increases in food prices, particularly affecting the most vulnerable populations. Climate change can result in food insecurity due to water resource scarcity, while soil degradation may worsen production problems. A quality harvest depends on optimal climatic conditions. However, climate change, characterized by infrequent or irregular precipitation and high temperatures, leads to a decrease in yield on one hand. On the other hand, these climate changes have an additional negative impact by deteriorating soils and reducing water resources through evaporation, reaching yield limits. Within this chapter, the authors explore the different interactions between plants, soil, water, and climate change. The objective is to design strategies specifically tailored to the changing climatic context, thus enabling the development of an agricultural sector that is both resilient and sustainable.
