This paper analyses the climate change projected for the near and distant future in South America using MRI/JMA (Japanese Meteorological Agency) global model simulations with resolutions of 20 and 60 km. Changes in mean climate, as well as in the annual cycles and interannual variability of temperature and precipitation are discussed. An analysis is also made of the uncertainties of the 60 km resolution model experiments. For the near and distant future, both, the 20 km and 60 km resolution MRI/JMA models project that temperature changes will be positive in all seasons.

Indigenous groups are increasingly combining traditional ecological knowledge and Western scientific approaches to inform the management of their lands. We report the outcomes of a collaborative research project focused on key ecological questions associated with monsoon vine thickets in Wunambal Gaambera country (Kimberley region, Western Australia). The study mapped monsoon rainforests and analysed the environmental correlates of their current distribution, as well as the historical drivers of patch dynamics since 1949.

The desertification is described as the land degradation occurring as a result of climate change and human activities in arid, semi-arid and semi-humid areas. In today’s world, climate change, desertification, land degradation and drought are amongst the most critical issues as they affect over 4 billion hectares of land in more than 164 countries, and directly impact approximately 1.5 billion people. These hazards threaten not only the environment, but also economy, security, development, food security and social life in Turkey as well as around the globe.

El control de la vegetación leñosa y la planificación posterior del pastoreo contribuirían a aumentar la oferta forrajera y la producción ganadera en pastizales del centro-oeste de la Provincia de La Pampa. El objetivo del presente trabajo fue comparar la dinámica de la vegetación y la respuesta animal en un pastizal rolado sometido a pastoreo continuo o pastoreo rotativo. La mitad de un área rolada de 200 ha se pastoreo en forma continua con terneros de recría, mientras que la restante mitad se pastoreo en forma rotativa mediante la subdivisión en cuatro parcelas de igual tamaño.

In order to create an optimal land use model and reduce the impact of erosion on agricultural land, a number of land conservation measures need to be introduced. The most effective set of measures that minimizes the manifestation of water erosion in erosion-hazardous areas is the contouring-reclamation organization of the territory. This complex of activities combines a protective reclamation structure that interacts with the terrain and soil protection technology of growing crops.

The final purpose of a package of works on recultivation is to create the desired conditions for activity of phyto-ameliorant crops (melilot, alfalfa), legume bacteria and oil oxidizing bacteria for cuttings slurry (CS) development. The activity parameters of legumes bacteria were studied in laboratory experiments on bean agar which showed that the introduction of calcium in the nutrient mixture 7 or more times increases the number of these bacteria in comparison with soda salinization.

The growing numbers of land change models makes it difficult to select a model at the beginning of an analysis, and is often arbitrary and at the researcher’s discretion. How to select a model at the beginning of an analysis, when multiple are suitable, represents a critical research gap currently understudied, where trade-offs of choosing one model over another are often unknown. Repeatable methods are needed to conduct cross-model comparisons to understand the trade-offs among models when the same calibration and validation data are used.

In this study, we compared pixel-based image analysis and object-based image analysis (OBIA) as methods of land cover classification of urban areas, using high resolution digital aerial photography. The study area was Setagaya Ward, Tokyo, Japan, and we carried out supervised classification using aerial photographs with 25-cm spatial resolution, and with both visible bands and a near infrared band. The overall accuracy of the object-based classification was approximately 6 to 20 percentage points higher than that of the pixel-based classification.
