Received: 29 September 2021;  Published: 30 December 2021;  doi: 10.21926/aeer.2104038

Abstract

Land-use change is one of the main indicators of soil quality. Soil physical and chemical properties vary with land use change and altitude as inferred from transect surveys and toposequences. Soil nitrogen, phosphorus, and potassium (NPK) are essential macronutrients for plant growth and soil nutrient balance. Their presence in the soil in appropriate quantities is important for maintaining crop yields and farmers income, particularly in developing countries where resources of soil [...]

Received: 08 October 2021;  Published: 15 December 2021;  doi: 10.21926/aeer.2104033

Abstract

Heavy metal(loid)s are a group of elements present commonly in the environment, including Cr, Ni, Cu, Zn, Cd, Hg, Pb, and As elements, among others. While these elements could have their origins in natural sources, anthropogenic activities, such as mining, agriculture, industry, etc., are also responsible for enhancing the concentration of these elements in the ecosystems up to undesirable levels. A few of these metal(loid)s serve as necessary micronutrients for life, while the other [...]

Architecture as Habitat: Enhancing Urban Ecosystem Services Using Building Envelopes

Received: 13 August 2021;  Published: 09 November 2021;  doi: 10.21926/aeer.2104029

Abstract

The practice of reconciliation ecology in urban environments relies heavily on urban green space as the primary source of vegetated habitat in cities. However, most cities lack the quantity, connectivity, and accessibility of green space needed to provide essential ecosystem services for the health, well-being, and resilience of human and non-human species. In reaction to urban densification and the increasing frequency and severity of climate change impacts, this study argues that a [...]
