Combined Use of Optical and Synthetic Aperture Radar Data for REDD+ Applications in Malawi

Peer-reviewed publication
December, 2018
Malawi

Recent developments in satellite data availability allow tropical forest monitoring to expand in two ways: (1) dense time series foster the development of new methods for mapping and monitoring dry tropical forests and (2) the combination of optical data and synthetic aperture radar (SAR) data reduces the problems resulting from frequent cloud cover and yields additional information.

Assessing the Spatial Drivers of Land Use and Land Cover Change in the Protected and Communal Areas of the Zambezi Region, Namibia

Peer-reviewed publication
December, 2018
Namibia

Understanding the patterns and drivers of land use and land cover (LULC) changes is fundamental for rational and specific planning for sustainable land management. Using remote sensing techniques, geographic information systems (GIS) and statistical modeling via multinomial logistic regression, we sought to identify spatial variables that determine LULC change and their extent over time in the protected and communal areas of the Zambezi Region, Namibia.

Trend Analysis of Las Vegas Land Cover and Temperature Using Remote Sensing

Peer-reviewed publication
December, 2018
Global

The Las Vegas urban area expanded rapidly during the last two decades. In order to understand the impacts on the environment, it is imperative that the rate and type of urban expansion is determined. Remote sensing is an efficient and effective way to study spatial change in urban areas and Spectral Mixture Analysis (SMA) is a valuable technique to retrieve subpixel landcover information from remote sensing images.

Perceptions and knowledge on land use and land cover changes and impact on resources and livelihoods in Nguruman Sub-catchment, Kajiado County, Kenya

Reports & Research
December, 2018
Kenya

Sustainable management of the natural resources requires critical understanding of the dynamics of land use and land cover change (LULCC). Nguruman sub-catchment in the northern part of Kajiado County has experienced rapid land use and land cover changed over the past decades. However, the extent to which these changes have impacted on the ecosystem and indigenous livelihoods has not been assessed. This remains a critical challenge that must be addressed due to its potential severe impacts on rural human livelihoods especially in arid and semi-arid areas in Kenya.

Effects of Land Use and Land Cover changes on Soil Organic Carbon and Total Nitrogen Stocks in the Olesharo Catchment, Narok County, Kenya

Kenya

Land Use and Land Cover Change (LULCC) is the most prominent cause of Soil Organic Carbon (SOC) variability in any landscape. Kenyan Arid and Semi-Arid Lands (ASALs) have been facing extensive land use/ cover changes in the last three decades prompting a review on the impacts it has on soil quality and consequently on land degradation. This study was carried out in 2016 in Olesharo Catchment, Narok County, one of the prominent ASALs of Kenya.

No significant difference in stream discharge is observed between bamboo andpine plantation catchments, and between cultivated and tea plantation catchments.

Analyses of land cover change trajectories leading to tropical forest loss : Illustrated for the West Kutai and MahakamUlu Districts, East Kalimantan, Indonesia

In Indonesia, land cover change for agriculture and mining is threatening tropical forests, biodiversity and ecosystem services. However, land cover change is highly dynamic and complex and varies over time and space. In this study, we combined Landsat-based land cover (change) mapping, pixel-to-pixel cross tabulations and expert knowledge to analyze land cover change and forest loss in the West Kutai and Mahakam Ulu districts in East Kalimantan from 1990-2009.

Trends.Earth (formerly the Land Degradation Monitoring Toolbox) is a platform for monitoring land change using earth observations in an innovative desktop and cloud-based system.

The three sub-indicators for monitoring achievement of Land Degradation Neutrality (LDN, Sustainable Development Goal (SDG) Target 15.3), are supported by: productivity, land cover, and soil organic carbon.

Identifying hotspots in land use land cover change and the drivers in a semi-arid region of India

Journal Articles & Books
December, 2018
India

The study examines long-term land use/land cover change (LUCC) at a finer scale in a semi-arid region of India. The objectives were to study and quantify the spatiotemporal LUCC and uncover the major drivers causing the change in the Mula Pravara river basin, which is located in a semi-arid region of Maharashtra state, India.

Cropland Abandonment in South African Smallholder Communal Lands: Land Cover Change (1950–2010) and Farmer Perceptions of Contributing Factors

Peer-reviewed publication
November, 2018
Global

Despite agricultural land abandonment threatening the food security and the livelihoods of smallholder farmers, it is pervasive globally and in developing countries. Yet land abandonment is an understudied aspect of land use change in social–ecological systems. Here we provide more information on this phenomenon by exploring cropland abandonment during 1950–2010 in four former South African ‘homelands’—part of the ‘Apartheid’ era racially-based land allocation programs—characterized by rural, smallholder farmers.

A classification to align social-ecological land systems research with policy in Europe

Peer-reviewed publication
November, 2018
Europe

Both research and policy recognize land systems as fundamental to human life and activities. However, these two perspectives approach land from different ends and it can be difficult to see how studied variables contribute to broader policy goals. In this paper, we argue that there is a need to better select variables to study land systems as social-ecological systems, and to align research more with those policy goals.

Estimation of Forest Area and Canopy Cover Based on Visual Interpretation of Satellite Images in Ethiopia

Peer-reviewed publication
September, 2018
Ethiopia

Forests, particularly in the tropics, are suffering from deforestation and forest degradations. The estimation of forest area and canopy cover is an essential part of the establishment of a measurement, reporting, and verification (MRV) system that is needed for monitoring carbon stocks and the associated greenhouse gas emissions and removals. Information about forest area and canopy cover might be obtained by visual image interpretation as an alternative to expensive fieldwork.
