The study, carried out at Laljhadi corridor in Kanchanpur district of Nepal, aimed at assessing forest cover change and fragmentation using multi-temporal Landsat data. Post classification change detection was applied on temporal forest cover class datasets obtained by supervised classification technique with maximum likelihood algorithm. The overa...

Wetlands are one of the most valuable ecosystems on the Earth for both humans and nature. Large-scale of wetlands have been transformed into agriculture and urban region in response to human demands and requirements. Accurate mapping and monitoring of large-scale wetlands are of high importance but also challenging. The growing availability of larg...

Phyllostachys pubescens (Moso bamboo) is a large monopodial bamboo species, naturally distributed in China and cultivated in neighboring countries. Seed availability of the P. pubescens is limited due to its long gregarious flowering cycle. Hence, developing nursery techniques from rhizome cuttings is necessary to fulfill the demand for Moso bamboo...

The land cover across the HKH region is changing at an accelerated rate due to the rapid economic growth and population pressures that are impacting the long-term sustainability of ecosystems.

While deforestation has traditionally been the focus for forest canopy disturbance detection, forest degradation must not be overlooked. Both deforestation and forest degradation influence carbon loss and greenhouse gas emissions and thus must be included in activity data reporting estimates, such as for the Reduced Emissions from Deforestation and...

Large-scale plantations of pine species were done in the bare hills of the Middle Mountain region of Nepal during the early 1980s. There is a growing concern on the sustainability of the planted pine forests in the country due to the presence of invasive alien plant species (IAPS). Invasive alien plant species are considered as one of the drivers o...

There is a growing agreement that conservation needs to be proactive and pay increased attention to common species and to the threats they face. The blue sheep (Pseudois nayaur) plays a key ecological role in sensitive high-altitude ecosystems of Central Asia and is among the main prey species for the globally vulnerable snow leopard (Panthera unci...

In the present context of rapid change which is occurring either due to the natural or artificial phenomenon, tracking environmental changes with the aid of remote sensing applications has been an important tool for multidisciplinary sectors. One of these applications is the construction of land use and land cover maps through the image classificat...

Land cover maps play an integral role in environmental management. However, countries and institutes encounter many challenges with producing timely, efficient, and temporally harmonized updates to their land cover maps. To address these issues we present a modular Regional Land Cover Monitoring System (RLCMS) architecture that is easily customized...

This study aimed to integrate and optimise multi-sensor data consisting of airborne laser scanning (ALS) and RapidEye image-derived parameters with field-measured biomass using Random forests (RF) to predict the tropical forest biomass (FB). The multi-sensor parameters which include combined spectral, textural and ALS derived 119 variables provided...

Land cover monitoring efforts are important for resource planning and ecosystem services in many countries. Collect Earth Online (CEO) is a new, free open source and user-friendly software tool for land monitoring. It is the product of a collaborative effort between NASA, Food and Agriculture Organization of the United Nations (FAO), US Forest Serv...

Restoration of Degraded Land

Developments in airborne LiDAR data acquisition have provided better horizontal and vertical ground information in form of 3D point clouds. This has led to satisfactory results of LiDAR-derived digital terrain models (DTMs), also across complex ecosystems like natural forest stands. However, data and site-driven factors such as spatial resolution (...

Land degradation is a major challenge in Nepal. A lot of degraded land is available within the Community Forests in the Mid-hills which are being aimed to be utilized for ecological restoration as well as supporting livelihoods of the local people. In this context, the study was conducted in the Chautaradanda Community Forest (27°44’05’’ N and 85o0...
