Why Landscape Beauty Matters

Peer-reviewed publication
Dezembro, 2014

This philosophical paper explores the aesthetic argument for landscape conservation. The main claim is that the experience of beautiful landscapes is an essential part of the good human life. Beautiful landscapes make us feel at home in the world. Their great and irreplaceable value lies therein. To establish this claim, the concepts of landscape and “Stimmung” are clarified. It is shown how “Stimmung” (in the sense of mood) is infused into landscape (as atmosphere) and how we respond to it aesthetically. We respond by resonating or feeling at home.

Landscape, Legal, and Biodiversity Threats that Windows Pose to Birds: A Review of an Important Conservation Issue

Peer-reviewed publication
Março, 2014

Windows in human residential and commercial structures in urban, suburban, and rural landscapes contribute to the deaths of billions of birds worldwide. International treaties, federal, provincial, state, and municipal laws exist to reduce human-associated avian mortality, but are most often not enforced for bird kills resulting from window strikes. As an additive, compared to a compensatory mortality factor, window collisions pose threats to the sustainability and overall population health of common as well as species of special concern.

Mapping Vegetation Morphology Types in Southern Africa Savanna Using MODIS Time-Series Metrics: A Case Study of Central Kalahari, Botswana

Peer-reviewed publication
Março, 2015

Savanna ecosystems are geographically extensive and both ecologically and economically important; they therefore require monitoring over large spatial extents. There are, in particular, large areas within southern Africa savanna ecosystems that lack consistent geospatial data on vegetation morphological properties, which is a prerequisite for biodiversity conservation and sustainable management of ecological resources.

Modeling Soil and Woody Vegetation in the Senegalese Sahel in the Context of Environmental Change

Climatic stress and anthropogenic disturbances have caused significant environmental changes in the Sahel. In this context, the importance of soil is often underrepresented. Thus, we analyze and discuss the interdependency of soil and vegetation by classifying soil types and its woody cover for a region in the Senegalese Ferlo. Clustering of 28 soil parameters led to four soil types which correspond with local Wolof denotations: Dek, Bowel, Dior and Bardial.

Historical Changes of Land Tenure and Land Use Rights in a Local Community: A Case Study in Lao PDR

Journal Articles & Books
Dezembro, 2016
Laos

Land-titling programs, land and forest allocation programs, and projects on state-allocated land for development and investment in Laos have been key drivers of change in land tenure. These have triggered major shifts in land use rights, from customary, to temporary, and then to permanent land use rights. This article explores how government programs to grant land use rights to individual households have affected the way people have been able to acquire and secure land tenure.

Assessment of Above-Ground Biomass of Borneo Forests through a New Data-Fusion Approach Combining Two Pan-Tropical Biomass Maps

Peer-reviewed publication

Indonésia
Brunei
Malásia

This study investigates how two existing pan-tropical above-ground biomass (AGB) maps (Saatchi 2011, Baccini 2012) can be combined to derive forest ecosystem specific carbon estimates. Several data-fusion models which combine these AGB maps according to their local correlations with independent datasets such as the spectral bands of SPOT VEGETATION imagery are analyzed. Indeed these spectral bands convey information about vegetation type and structure which can be related to biomass values. Our study area is the island of Borneo.

Toward the Integrated Framework Analysis of Linkages among Agrobiodiversity, Livelihood Diversification, Ecological Systems, and Sustainability amid Global Change

Peer-reviewed publication
Junho, 2016

Scientific and policy interest in the biological diversity of agriculture (agrobiodiversity) is expanding amid global socioeconomic and environmental changes and sustainability interests. The majority of global agrobiodiversity is produced in smallholder food-growing.

Agriculture on the Brink: Climate Change, Labor and Smallholder Farming in Botswana

Peer-reviewed publication
Setembro, 2016

Botswana is a semi-arid, middle-income African country that imports 90 percent of its food. Despite its relative prosperity, Botswana also suffers from one of the highest measures of income inequality in the world, persistent poverty, and relatively high levels of food insecurity. The objective of this paper is to explore how political economy, climate change and livelihood dynamics are synergistically impacting household food security.

Do Smallholder, Mixed Crop-Livestock Livelihoods Encourage Sustainable Agricultural Practices? A Meta-Analysis

Peer-reviewed publication
Março, 2016

As calls for bolstering ecosystem services from croplands have grown more insistent during the past two decades, the search for ways to foster these agriculture-sustaining services has become more urgent. In this context we examine by means of a meta-analysis the argument, proposed by Robert McC. Netting, that small-scale, mixed crop-livestock farming, a common livelihood among poor rural peoples, leads to environmentally sustainable agricultural practices.

Using an Agroecosystem Services Approach to Assess Tillage Methods: A Case Study in the Shikma Region

Peer-reviewed publication
Dezembro, 2015

The use of ecosystem services (ES) in agricultural management is expanding; however, its integration in decision making processes is still challenging. This project was formulated to examine the ES approach and its usefulness with regard to management dilemmas. The Shikma region, north of the Negev Desert, was chosen as a case study. The management issue identified was the effect of various alternatives (minimum-tillage, no-tillage, straw-mulch and stubble-grazing) on the supply of ES.

How Land Concessions Affect Places Elsewhere: Telecoupling, Political Ecology, and Large-Scale Plantations in Southern Laos and Northeastern Cambodia

Peer-reviewed publication
Junho, 2015
Vietnam
Laos
Cambodja

Over the last decade considerable research has been conducted on the development and the impacts of large-scale economic land concessions for plantations in Laos and Cambodia. These studies have variously illustrated that concessions frequently result in serious negative impacts on local people and the environment, often leading to dramatic transformations of landscapes and livelihoods. As important as this research has been, these studies have largely focused on the immediate impacts of the “enclosure” process associated with gaining access to land by investors.
