Tree root systems stabilize hillslopes and riverbanks, reducing landslide risk, but related data for the humid tropics are scarce. We tested fractal allometry hypotheses on differences in the vertical and horizontal distribution of roots of trees commonly found in agroforestry systems and on shear strength of soil in relation to root length density in the topsoil. Proximal roots of 685 trees (55 species; 4–20 cm stem diameter at breast height, dbh) were observed across six landscapes in Indonesia.
Assessing Ecosystem Services Supplied by Agroecosystems in Mediterranean Europe: A Literature Review
Agricultural landscapes in the Mediterranean region may be considered as social-ecological systems that are important for biodiversity conservation whilst contributing to a wide range of ecosystem services. This literature review aims to identify the current state and biases of ecosystem service assessment in agroecosystems within the Mediterranean region, evaluate pressures impacting on agroecosystems and their services, and practices that promote ecosystem service synergies in Mediterranean agroecosystems.
Rururban Partnerships: Urban Accessibility and Its Influence on the Stabilization of the Population in Rural Territories (Extremadura, Spain)
The process of population concentration in cities is a worldwide phenomenon—not yet finished—which has led to a widespread rural exodus and abandonment of rural areas. In Spain it occurred very abruptly from 1960, leaving numerous population centers abandoned in the northern half of the country. It is the so-called “empty Spain”. This problem has recently transcended from the local to the European level and has become part of all political agendas such as “the fight against the demographic challenge”, which the European Commission will finance in the next programming period 2021–2027.
Connectivity of Protected Areas: Effect of Human Pressure and Subnational Contributions in the Ecoregions of Tropical Andean Countries
Conservationists recognize the value of protected area (PA) systems, with adequate coverage, ecological representation, connection, and management to deliver conservation benefits. Yet, governments primarily focus on coverage, disregarding quantification of the other criteria.
Cultural Memories and Sense of Place in Historic Urban Landscapes: The Case of Masrah Al Salam, the Demolished Theatre Context in Alexandria, Egypt
Historic urban landscapes (HULs) are composed of layers of history and memories that are embedded in physical monuments, buildings, and memorials. Physical built fabric stores both personal and cultural memory through long association with communities. Rapid changes due to demolition and redevelopment change the nature of these places and, in turn, affect these memory storages. This paper investigates whether historical city inhabitants consider cultural memories important when managing their HULs.
