Monitoring Mangrove Forest Dynamics of the Sundarbans in Bangladesh and India using Multi-Temporal Satellite Data from 1973 to 2000

Background

In the Sundurbans of India and Bangladesh, the authors measured the extent and condition of the mangrove forest at three intervals using GeoCover datasets (Landsat MSS, TM, ETM+) with the goal of assessing the current extent of the remaining forest, measuring change in the extent of the forest in different time periods, and identifying areas of intensive deforestation or degradation and changes in patterns of canopy density.

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.

The Impact of Forest Use and Reforestation on Soil Hydraulic Conductivity in the Western Ghats of India: Implications for Surface and Sub-Surface Hydrology

background

This article presents research on the surface and sub-surface permeability of degraded and restored forests and their dominant stormflow pathways  in the humid tropics of Uttar Kannada district, Karnataka, India. The authors attempt to determine to what extent field saturated hydraulic conductivity (K*) isaltered due to long-term forest degradation as compared to other studies in the humid tropics. They quantify changes in permeability following forestation of plantations and degraded landscapes and investigate the likely effect of wet-season conditions and the implications this has for predicting hydrologic consequences of forest degradation.

Drivers of Regrowth in South Asia's Human-Impacted Forests

background

This study is an assessment of institutional factors and human drivers that impact forest management and cover change in developing countries, focusing on Nepal and India.

research goals & methods

The study uses United Nations Food & Agriculture Association (UN FAO) forest cover change datasets that begin in 1980 to examine the validity of forest transition theories in a tropical context.

The Rain–Runoff Response of Tropical Humid Forest Ecosystems to Use and Reforestation in the Western Ghats of India

Background

This study expands on a previous study in the Western Ghats of India (Uttar Kannada, Karnataka State), that suggested a greater occurrence of infiltration-excess and potentially higher streamflow in degraded and reforested areas. Analyzing rainfall–streamflow data, the authors attempt to determine the impacts of different land cover types on stream discharge hydrograph components (viz, total flow, quickflow and delayed flow), the dominant stormflow pathways, and the impact of reforestation efforts on these processes.

Reforestation of Bauxite Mine Spoils with Eucalyptus tereticornis Sm. Seedlings Inoculated with Arbuscular Mycorrhizal Fungi

background

In the Yercaud hills of the Salem Distict, Tamil Nadu, India, the authors investigated the feasibility of using trees inoculated with beneficial mycorrhizae as an alternative to the traditional and more expensive method of spreading topsoil before planting

Afforestation and Reforestation Projects in South and South-East Asia Under the Clean Development Mechanism: Trends and Development Opportunities

background

The Clean Development Mechanism (CDM) was created as part of the 2007 Kyoto Protocol to assist countries in achieving both development and sustainability. Afforestation and reforestation (AR) projects are a part of the CDM protocal, but can be challenging to implement and measure.

research goals & methods

This study reports on survey results regarding CDM-AR projects. Surveys were conducted in South and South-east Asia of both (i) experts and (ii) developers, investors, and consultants.

Integrating National Forestry Initiatives in India with International Climate Change Policy

background

This study reviews forest policies in India (eg. 1988 Forest Policy, 1990 Joint Forest Management, and 2006 Recognition of Forest Rights) and their impacts to assess how they can complement and inform international climate change mitigation instruments. It also seeks to determine how communities can sustain their system of forest management and retain/obtain rights to land and resources under these instruments.

Changes in litter decomposition and soil organic carbon in a reforested tropical deciduous cover (India)

Background

Soil organic carbon is built over time by vegetative decomposition. This study explores potential changes in soil organic carbon in India due to changing patterns of vegetation, such as deforestation, agricultural use, and reforestation with novel species compositions and disturbance cycles.

Quantitative Assessment of People-Oriented Forestry in Bangladesh: A Case Study in the Tangail Forest Division

background

This research evaluates the profitability of three different types of plantation - strip, agroforestry, and woodlot - grown via a people-oriented forestry program in Bangladesh.

Research Goals & Methods

This research is based on case study analysis and utilizes participant interviews, focus group discussions, and analyzing annual costs from the Tangail Divisional Forest office.  From this data, the researchers were able to describe net present values and benfit-cost ratios.
