Landscape-Scale Disturbance: Insights into the Complexity of Catchment Hydrology in the Mountaintop Removal Mining Region of the Eastern United States

Peer-reviewed publication
Septiembre, 2016

Few land disturbances impact watersheds at the scale and extent of mountaintop removal mining (MTM). This practice removes forests, soils and bedrock to gain access to underground coal that results in likely permanent and wholesale changes that impact catchment hydrology, geochemistry and ecosystem health. MTM is the dominant driver of land cover changes in the central Appalachian Mountains region of the United States, converting forests to mine lands and burying headwater streams.

Development by Design in Western Australia: Overcoming Offset Obstacles

Peer-reviewed publication
Marzo, 2014
Australia

Biodiversity offsets can be an important tool for maintaining or enhancing environmental values in situations where development is sought despite negative environmental impacts. There are now approximately 45 compensatory mitigation programs for biodiversity impacts worldwide, with another 27 programs in development. While offsets have great potential as a conservation tool, their establishment requires overcoming a number of conceptual and methodological hurdles.

Growth of different tree species and their nutrient uptake in limestone mine spoil as influenced by arbuscular mycorrhizal (AM)-fungi in Indian arid zone

Journal Articles & Books
Diciembre, 2002

The mining and quarrying of mineral ores lead to conflicts between the ideals of economic prosperity and landscape preservation. Rehabilitation/revegetation of mine spoils has received considerable attention in recent years due to acceleration of mining and associated land disturbances. This is an attempt towards rehabilitation of limestone mine spoils in arid areas where water and nutrients are the main constraints even in normal soil.

Effects of land use patterns on the diversity and conservation status of butterflies in Kisii highlands, Kenya

Journal Articles & Books
Diciembre, 2015
Kenya

Habitat degradation poses a great threat to biodiversity conservation. Abundance and diversity of butterflies is an indicator of good environmental health. Understanding how different butterfly species respond to habitat degradation is a necessary step towards the development of effective measures to enhance environmental protection. This study investigated the impact of land use patterns on the diversity, abundance, and conservation status of butterflies in the Kisii highlands; a densely-populated region in Kenya that has received little attention in ecological studies.

Reconstruction of contested landscape: Detecting land cover transformation hosting cultural heritage sites from Central India using remote sensing

India

Central India hosts one of the largest repositories of archaeological sites in the world having a semi-arid climate and distinct eco-geography which is prone to rapid change due to human activities. This paper discusses the changes in land use and land cover for the past twenty-three years in the region altering the rich cultural heritage, revealing by the presence of numerous painted rock-shelter sites in the region. The land cover and land use changes in terms of deforestation, urban growth and development and sandstone mining have been evaluated in the present study.

Response of dissolved trace metals to land use/land cover and their source apportionment using a receptor model in a subtropic river, China

Journal Articles & Books
Diciembre, 2011
China

Water samples were collected for determination of dissolved trace metals in 56 sampling sites throughout the upper Han River, China. Multivariate statistical analyses including correlation analysis, stepwise multiple linear regression models, and principal component and factor analysis (PCA/FA) were employed to examine the land use influences on trace metals, and a receptor model of factor analysis-multiple linear regression (FA-MLR) was used for source identification/apportionment of anthropogenic heavy metals in the surface water of the River.

Biology and establishment of mountain shrubs on mining disturbances in the Rocky Mountains, USA

Journal Articles & Books
Diciembre, 2003
Estados Unidos de América

The Rocky Mountains of the western United States contain many economically important natural resources. Increasing development of these resources has lead to land degradation, which often requires restoration efforts. A common type of disturbance in this region is mineral extraction and these activities often occur in zones of vegetation dominated by shrubs. These mined lands have proven to be particularly challenging to restore to native shrub cover.

Shifting rights, property and authority in the forest frontier: ‘stakes’ for local land users and citizens

África

Customary land and forests are more embedded in the global economy than ever. With globally significant supplies of land and raw materials and favorable terms for foreign investors, developing countries – particularly in Africa – have become increasingly attractive trade partners and destinations for investors. Increasing competition over land is placing new pressures on vast tracts of forest and woodland, areas often considered ‘under-utilized’ by national governments despite their critical role in supporting local livelihoods.

environmental narrative of Inland Northwest United States forests, 1800–2000

Journal Articles & Books
Diciembre, 2003
Estados Unidos de América

Fire was arguably the most important forest and rangeland disturbance process in the Inland Northwest United States for millennia. Prior to the Lewis and Clark expedition, fire regimes ranged from high severity with return intervals of one to five centuries, to low severity with fire-free periods lasting three decades or less. Indoamerican burning contributed to the fire ecology of grasslands and lower and mid-montane dry forests, especially where ponderosa pine was the dominant overstory species, but the extent of this contribution is difficult to quantify.

How does ‘Free, Prior and Informed Consent’ (FPIC) impact social equity? Lessons from mining and forestry and their implications for REDD+

Journal Articles & Books
Diciembre, 2013

The principle of “Free, Prior and Informed Consent” (FPIC) is promoted through international agreements and safeguards in order to strengthen social equity in resource management by requiring consent from indigenous and/or local communities prior to actions that affect their land and resource rights. Based on early experiences with implementing FPIC standards in mining and forestry, we examine how FPIC has impacted social equity and why. In both sectors FPIC was first operationalized through non-governmental standards that revealed ambiguities surrounding its definition and implementation.

Some observations about man-made features on natural terrain in Hong Kong

Hong Kong

Much of Hong Kong is currently undeveloped and consists of vegetated, relatively steep hillsides, which are considered to be natural terrain. However, in many of these areas there is evidence in old aerial photographs of man-made features, which for the last 30–40 years or so have been hidden by dense vegetation. Before the 1970s the vegetation was considerably less dense than today and much of the ground surface was bare and clearly apparent.
