Assessment of Spatial-Temporal Expansion of Built-up and Residential-Commercial Dwellings with Some Economic Implications: A Case Study in the Lower Hunter of Eastern Australia

Peer-reviewed publication
Marzo, 2014

Built-up areas have been expanding throughout the world. Monitoring and prediction of the build-up is not only important for the economic development but also acts as sentinels of environmental decline important for ecologically sustainable development of a region. The aim of this paper is to model the growth of built-up and residential-commercial dwellings over the recent past and thus predict the near future growth for a popular tourist destination of the Lower Hunter of New South Wales, Australia.

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

Peer-reviewed publication
Marzo, 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.

Understanding Land Cover Changes in the Italian Alps and Romanian Carpathians Combining Remote Sensing and Stakeholder Interviews

Peer-reviewed publication
Marzo, 2014

In the last two decades, socio-economic changes in Europe have had a significant effect on land cover changes, but it is unclear how this has affected mountain areas. We focus on two mountain areas: the eastern Italian Alps and the Romanian Curvature Carpathians. We classified land cover from Earth observation data after 1989 by using applied remote sensing techniques. We also analyzed socio-economic data and conducted semi-structured interviews with local stakeholders. In Italy, most of the land conversion processes followed long-term trends.

Interrelationships of Land Use/Cover Change and Topography with Soil Acidity and Salinity as Indicators of Land Degradation

Peer-reviewed publication
Marzo, 2014

As soil is the basis of all terrestrial ecosystems, degraded soil means lower fertility, reduced biodiversity and reduced human welfare. Therefore the focus of this paper is on elucidating the influence of land use and land cover (LULC) change on two important soil quality indicators that are fundamental to effective measures for ameliorating soil degradation; namely soil acidity and soil salinity in the Lower Hunter Valley of New South Wales, Australia. First, Analysis of Variance was used to elucidate the effects of LULC categories on soil acidity and salinity.

Analyzing Vegetation Change in an Elephant-Impacted Landscape Using the Moving Standard Deviation Index

Peer-reviewed publication
Marzo, 2014
Botswana

Northern Botswana is influenced by various socio-ecological drivers of landscape change. The African elephant (Loxodonta africana) is one of the leading sources of landscape shifts in this region. Developing the ability to assess elephant impacts on savanna vegetation is important to promote effective management strategies. The Moving Standard Deviation Index (MSDI) applies a standard deviation calculation to remote sensing imagery to assess degradation of vegetation.

Restoration of Prairie Hydrology at the Watershed Scale: Two Decades of Progress at Neal Smith National Wildlife Refuge, Iowa

Peer-reviewed publication
Marzo, 2014

Tallgrass prairie once occupied 67.6 million hectares in the North American Midwest but less than 0.1% remains today. Consisting of more than 2200 ha, Neal Smith National Wildlife Refuge (NSNWR) was established by the US Fish and Wildlife Service in the 5217 ha Walnut Creek watershed in Jasper County, Iowa. Large tracts of land are being converted from row crop agriculture to native prairie and savanna with the goal to restore the landscape to a semblance of the condition that existed prior to Euro-American settlement.

Sustainably financing extension services

Journal Articles & Books

Global

Providing extension and advisory services is expensive. There are salaries to be paid, transporta­tion and operational funds to be provided, buildings to be rented or built, demonstration plots to maintain, and continued education to be offered to the extension staff. And then there is the need to continually invest in an overall functioning agricultural innovation system with strong research and teaching institutions, enabling policies, as well as to make capital investments in rural infrastructure that will not only benefit the farming population.

In many parts of Africa, formal education and training in agriculture is almost nonexistent. Swiss Biovision Foundation supports farmers via its Farmer Communication Programme. While it takes advantage of its close links with research institutions, the ideas and experiences of farmers also flow directly into its course contents.

Etiopía

Despite growing research on land deals in Ethiopia, there is still uncertainty on the real scale and features of the phenomenon, and some misperceptions continue to shape public debates. Report discusses the findings of a systematic inventory of land deals for agricultural investment in Ethiopia. It describes the scale, geography, drivers and key features of large-scale deals. It also discusses findings relating to the early outcomes of the deals.
