Land Use Change and Trends

The Recovery of the Lower Montane Cloud Forest in the Mucujún Watershed, Mérida, Venezuela

Background

Given the recovery of degraded forests in some landscapes throughout the tropics, the authors analyze land use change and land cover change in a mountain region of the andes of venezuela during a period of 50 years.

Research Goals & Methods

The study relies on aerial photographs taken between 1952 and 2009 of a peri-urban watershed.

Carbon sequestration versus bioenergy: A case study from South India exploring the relative land-use efficiency of two options for climate change mitigation

background

This study explores avenues to meet increased rural electricity demand with carbon emissions mitigation. The study compares the option of energy derived from gasification of biomass from forest plantations to energy derived from fossil fuels, with forest plantations used as a carbon sink.The case study uses power demand, land requirements, and management approaches for Hosahalli village, Karnataka, pop. 218.

Simulating Forest Cover Changes of Bannerghatta National Park Based on a CA-Markov Model: A Remote Sensing Approach

Background

Establishment of protected areas has been a primary response to deforestation and land-use change in tropical forests. However, few empirical evaluations have conducted a comparison of pre- and post-intervention landscapes.

Effect of Vegetation Restoration on Soil and Water Erosion and Nutrient Losses of a Severely Eroded Clayey Plinthudult in Southeastern China

Background

In this study, researchers compare erosion from reforested and degraded sites in subtropical southeastern China.

Goals & Methods

The objective of the study was to estimate the long-term influences of reforestation on soil and water erosion and nutrient losses in regions of southeast China that are characterized by severely eroded bare land derived from Quaternary red clay. The study examined surface runoff, soil erosion, and soil nutrient content.

One Century of Forest Rehabilitation in the Philippines: Approaches, Outcomes, and Lessons

background

This chapter provides a review of reforestation efforts in the Philippines, beginning with small-scale forest rehabilitation efforts since 1910. Reforestation was traditionally implemented by government and private companies. Since the mid-1970s, international funders have driven these efforts.

Tropical Reforestation in the Asia-Pacific Region

background

This chapter reviews the meaning and implementation of landscape scale restoration in the Asia-Pacific region.  The authors define landscape as a spatial mosaic with differing land use patterns across a gradient, usually involving natural and human-intervened areas which changes through time.

Effects of forest clearing and succession on the carbon and nitrogen content of soils in Puerto Rico and US Virgin Islands

Background

Conversion of tropical forest lands to agriculture or pasture affects soil organic matter, moisture, and nutrients. This study examines the effects on soil carbon, nitrogen, and moisture at depths up to 100 cm of conversion from forest to agriculture and pasture.

Land Use Transitions: Socio-Ecological Feedback versus Socio-Economic Change

background

This study seeks to understand the social, environmental, and economic factors that influence land use transition and how those factors influence resulting forest quality. The study looks at both at forest loss and reforestation. The authors use recent changes in forest cover in northern Vietnam as a case study.
