En milieu montagnard tropical, où les risques d'érosion sont naturellement élevés, la mise en culture des terres entraîne l'aggravation des processus. Ainsi, les versants des Andes équatoriennes, intensément cultivés, connaissent une érosion qui affecte la fertilité des sols et donc la production agricole dont dépend le petit paysannat (minifundio) pour son alimentation. Il est urgent d'apporter des mesures de lutte antiérosives efficaces et adaptées aux conditions socio-économiques de la population. Mais les connaissances sur l'érosion et la lutte antiérosive dans le monde tropical, en particulier dans les milieux montagnards, sont encore fragmentaires, les scientifiques ayant longtemps privilégié l'étude théorique des processus. L'objectif de la recherche présentée dans cet ouvrage est de proposer une approche qui associe recherche fondamentale et appliquée permettant la mise en œuvre pratique de méthodes de lutte érosive. Cette étude s'est déroulée en trois étapes : diagnostic de l'érosion, mesures des processus, proposition et validation de méthodes antiérosives. Menée à l'échelle du terroir et de la parcelle paysanne, suivant une démarche formative et participative associant paysans, chercheurs et décideurs, elle montre que la lutte contre l'érosion est possible sur les hautes terres andines. Cette approche peut servir d'exemple pour poser les bases d'une agriculture de montagne durable en milieu tropical. Cet ouvrage s'adresse aux universitaires et chercheurs en géographie, pédologie, hydrologie et agronomie et par sa présentation didactique aux étudiants ainsi qu'aux décideurs. Ecuadoris a mountainous, volcanic country typical of the tropical part of the Andes range. The situation in the mountains—the Sierra—is special. Following an agrarian reform process with questionable results, many small farmers were shifted to slopes and highland areas, where many small cropped fields form a checkerboard pattern with low productivity, the «minifundio». This highland…

This open access book includes a series of relevant policy research articles, elaborared in the framework of the “Quality in higher education: internationalisation and databases to enhance the Romanian education system” project, implemented by the Executive Agency for Higher Education, Research, Development and Innovation Funding (UEFISCDI), together with the Ministry of Education. The project aims to develop and implement systemic measures at tertiary education level, leading to an increased quality of the overall higher education system and universities better prepared for labour market requirements and international standards. The book focuses on areas of interest for Romanian higher education, such as systemic measures to improve access, participation and completion for (vulnerable) students, better promotion of the Romanian higher education to attract students, as well as instruments for a more efficient use of data at higher education level. Each article includes evidence-based policy proposals that could support new strategic initiatives in higher education, including new legislation. Additionally, the collection of articles tells a comprehensive story about the audacity of a higher education system which went through significant challenges to align itself with both European and international trends, as well as respond to national imperatives. Over the last three decades, since the fall of the Iron Curtain, Romanian higher education has undergone significant transformations, aiming to align itself to the latest developments and trends at European and international level. The National Law on Education no. 1/2011 has set the stage for a full implementation of the Bologna Process action lines, taking into account that Romania was already a part of the largest European intergovernmental process – currently the European Higher Education Area (EHEA) – as a founding member. However, since the adoption of this normative framework, the law suffered numerous amendments, making it challenging to observe and achieve coherence in its implementation. Furthermore, Romania is also currently redesigning the strategy for the alocation of European structural funds 2021-2027, based on two strategic documents - the new Education and Employment Operational Programme and the National Recovery and Resilience Plan which highlight the reform and investment priorities at a national level. At the same time, 2021 is a good time to analyze the level of implementation for the objectives and measures included in the National Strategy for Tertiary Education 2015-2020, the Europe 2020 Strategy, and the Bologna Process action lines in the 2010 – 2020 timeframe. Therefore, the present moment may be an important time to assess the impact of strategic documents and actions in the last decade and, possibly, to draft a new National Education Law, better adapted to current realities, starting from the recent initiative by the President of Romania – the Educated Romania strategic vision which was also politically assumed by the Romanian Government.

Concerns have been raised with respect to the state of high-altitude and high-latitude treelines, as they are anticipated to undergo considerable modifications due to global changes, and especially due to climate warming. As high-elevation treelines are temperature-limited vegetation boundaries, they are considered to be sensitive to climate warming. As a consequence, in this future, warmer environment, an upward migration of treelines is expected because low air and root-zone temperatures constrain their regeneration and growth. Despite the ubiquity of climate warming, treeline advancement is not a worldwide phenomenon: some treelines have been advancing rapidly, others have responded sluggishly or have remained stable. This variation in responses is attributed to the potential interaction of a continuum of site-related factors that may lead to the occurrence of locally conditioned temperature patterns. Competition amongst species and below-ground resources have been suggested as additional factors explaining the variability in the movement of treelines. This Special Issue (book) is dedicated to the discussion of treeline responses to changing environmental conditions in different areas around the globe.
