The tropical seasonal rainy evergreen broad-leaved forest vegetation of the Cucphoung National Park has been classified and the distribution of plant communities has been shown on the map using the relations of vegetation to geology, geomorphology and pedology. The method of vegetation mapping includes: 1) the identifying of vegetation types in the remote-sensed materials (aerial photographs and satellite images); 2) field work to compile the interpretation keys and to characterize all the communities of a study area; 3) compilation of the final vegetation map using the combined information. In the classification presented a number of different level vegetation units have been identified: formation classes (3), formation sub-classes (3), formation groups (3), formations (4), subformations (10) and communities (19). Communities have been taken as mapping units. So in the vegetation map of the National Park 19 vegetation categories has been shown altogether, among them 13 are natural primary communities, and 6 are the secondary, anthropogenic ones. The secondary succession goes through 3 main stages: grassland herbaceous xerophytic vegetation, xerophytic scrub, dense forest.

AbstractGlacier monitoring enables us to detect influences of global warming in high mountain regions. To initiate the establishment of a glacier-monitoring network in northern Eurasia, we studied recent glacier variations in Mongolia using topographical maps, aerial photographs and satellite images (Corona and Landsat). Glaciers in Mongolia exist in the Altai mountains which span approximately 1400 km within Russia, China and Mongolia. Four regions were selected to form the study area: Tavan Bogd region, Turgen massif, Kharkhiraa massif and Tsambagarav massif. During the period from the 1940s to 2000 or from 1968 to 2000, the glaciers in these regions lost 10.2%, 19.3%, 28.0% and 28.8% of their area respectively. The glaciers in the Tavan Bogd, Kharkhiraa and Turgen regions were found to have been almost stationary since 1987/88, while those in Tsambagarav massif showed no significant change in area since 1963. Shrinkage of the glaciers occurred between 1945/68 and 1987/88 in the former regions and between 1948 and 1963 in the latter. Mongolian glaciers seem to behave differently from other glaciers which have been experiencing steady shrinkage recently.

A massive magnitude 9.0 earthquake occurring on March 11, 2011, triggered a powerful tsunami that devastated large areas along Japan’s eastern Pacific coast. We investigated tsunami damage using satellite images and aerial photographs, and visited devastated sites, including 27 Shinto shrines, near the coast in 2011 and 2012. We found that all but two of these shrines survived the tsunami, even though tsunami height differed from place to place. As a memorial to those who lost their lives in previous tsunamis, shrines were built in places to which residents could safely evacuate. Many of these shrines were undamaged because their elevation was higher than the tsunami height, and the lives of those who evacuated to them were saved.

Este estudo consiste na sistematização de uma experiência agroecológica a partir do ordenamento e síntese dos processos do seu uso e ocupação. A experiência iniciou em 1984, em unidade agroecológica pioneira, com características neorurais, na região Centro-oeste do Brasil. A pesquisa contou com entrevistas não estruturadas, levantamento de campo, pesquisa bibliográfica e documental (fotografias, revistas, jornais, imagens de satélite e fotografias aéreas). Utilizou-se a ferramenta Google Earth para avaliar o mosaico de agroecossistemas resultante da ação agroecológica no espaço e tempo. Os resultados apontaram uma dinâmica complexa do processo de construção de agroecossistemas e redes sociais, configurando-se num desenho agroecológico que ultrapassa as fronteiras físicas da propriedade. O processo de síntese e análise relatado, além de empoderar os protagonistas, traz a luz do conhecimento científico aprendizados de uma experiência empírica de um modo de vida integrado à natureza, com riqueza em variedade, diversidade e possibilidades nos processos biológicos, sociais, econômicos, éticos, morais e culturais, que pode inspirar e subsidiar outras iniciativas de base agroecológica. Palavras-chave: neoruralidade; gerenciamento agroecológico; redesenho da paisagem; agroecossistemas.   Systematization of an agroecological experience in the Brazilian Cerrado: subsidies for the planning of productive units of ecological bases   ABSTRACT: This study consists of the systematization of an agroecological experience from the ordering and synthesis of the processes of its use and occupation. The experience began in 1984, in a pioneering agroecological unit, with neorural characteristics, in the Midwest region of Brazil. The research included unstructured interviews, field surveys, bibliographic and documentary research (photographs, magazines, newspapers, satellite images, and aerial photographs). The Google Earth tool was used to evaluate the mosaic of agroecosystems resulting from agroecological action in space and time. The results pointed toward a complex dynamic of the construction process of agroecosystems and social networks, configuring itself in an agroecological design that goes beyond the physical boundaries of the property. The reported process of synthesis and analysis, in addition to empowering the protagonists, brings to light scientific knowledge learning from an empirical experience of a way of life integrated with nature, with a wealth of variety, diversity, and possibilities in biological, social, economic, ethical, moral and cultural processes, which can inspire and subsidize other agroecological initiatives. Keywords: neorurality; agroecological management; landscape redesign; agroecosystems.
