Introduced as a soil erosion deterrent, salt cedar has become a menace along riverbeds in the desert southwest. Salt cedar replaces native species, permanently altering the structure, composition, function, and natural processes of the landscape. Remote sensing technologies have the potential to monitor the level of invasion and its impacts on ecosystem services. In this research, we developed a species map by segmenting and classifying various species along a stretch of the Lower Gila River.
Dairy Joint Ventures in South Africa’s Land and Agrarian Reform Programme: Who Benefits?
Joint Ventures (JVs) between ‘agribusiness’ investors and ‘small farmers’ or ‘customary landowners’ are being promoted in South Africa’s land and agrarian reform programme as a way to include land reform beneficiaries in the country’s competitive agricultural sector. This paper undertakes an in-depth comparative analysis of two JV dairy farms located on irrigation schemes in the former ‘homeland’ of the Ciskei, in South Africa’s Eastern Cape Province. The community, through government investment, brings the fixed assets to the business: land, irrigation infrastructure and milking parlours.
Future Directions—Engaged Scholarship and the Climate Crisis
Climate change has the potential to disrupt ecosystem services and further exacerbate the effects of human activities on natural resources. This has significant implications for educational institutions and the populations they serve. As the current crop of landscape architecture students struggles to define its role within the climate crisis and its related social and political underpinnings, a core mission of colleges and universities moving forward should be to provide students with applied knowledge about how climate change affects the landscape.
Understanding Landscape Identity in the Context of Rapid Urban Change in China
China is one of the most rapidly urbanising countries in the world. In recent years, it has experienced enormous environmental changes, as well as a loss of landscape identity. This paper aims to explore the concept of landscape identity in the context of the overwhelming urbanisation in China. It develops a conceptual framework on landscape identity from different dimensions. Factors are also identified that drive the urban changes with regard to the landscape identity that develops over time.
Classification of Landforms for Digital Soil Mapping in Urban Areas Using LiDAR Data Derived Terrain Attributes: A Case Study from Berlin, Germany
In this study, a knowledge-based fuzzy classification method was used to classify possible soil-landforms in urban areas based on analysis of morphometric parameters (terrain attributes) derived from digital elevation models (DEMs). A case study in the city area of Berlin was used to compare two different resolution DEMs in terms of their potential to find a specific relationship between landforms, soil types and the suitability of these DEMs for soil mapping.
