Resumen Este artículo presenta los pasos metodológicos para el análisis histórico del uso del suelo usando sistemas geográficos de información, SIG, y sensores remotos, SR. Así mismo, muestra la aplicación de estas técnicas a un estudio de caso para la producción de herramientas digitales que puedan servir para planear y administrar zonas agrícolas de una forma eficiente y sostenible. En el estudio se describe como fotos aéreas de 1973 a 2001, y una imagen de satélite, fueron usadas para generar mapas básicos, mapas de cambio de uso del suelo, así como de unidades administrativas agrícolas. En este estudio se muestra como los mapas y tablas además de otros análisis generados con los sistemas SIG-SR se convierten en una importante estructura analítica para la toma de decisiones en el sector rural. Palabras clave: Uso del suelo, planificación rural, SIG, sostenibilidad   Abstract This paper discusses the use of geographic information systems, GIS, supported by remote sensing, RS, data as an important tool in the day to day decision making process on agriculture areas. The study is used to demonstrate how historical aerial photographs and a satellite image from 1973 to 2001 were used to produce land use, and land use change maps as well as maps of agriculture units for the study area that are later used for planning purposes of agriculture activities. The paper summarizes the methodological steps followed in the GIS analysis and the way that GIS-RS systems can be used in rural areas to plan and to manage day to day activities in agriculture areas under the philosophy of sustainable agriculture. Keywords: Sustainable agriculture, GIS, rural planning

Planning Methodology

Objetivou-se com este estudo definir uma metodologia de planejamento que possibilite a análise da estrutura de determinada paisagem e de suas características bióticas e abióticas, para a elaboração de um zoneamento adequado do uso do solo. As principais diretrizes do estudo foram a manutenção da estabilidade hídrica e o aumento da conectividade na microbacia, por meio da identificação de zonas de maior fragilidade ambiental, considerando a hidrografia, a geomorfologia, a pedologia e a distribuição dos fragmentos florestais remanescentes. A pesquisa de campo foi realizada com auxílio de imagens de satélite e fotografias aéreas em uma microbacia com 4.629,47 ha no entorno do Parque Nacional do Iguaçu, Terceiro Planalto Paranaense. Foram efetuados diferentes diagnósticos dos aspectos bióticos e abióticos, resultando em uma simulação do uso adequado do solo e no aumento da conectividade com a formação de corredor ecológico. A aplicabilidade do método foi demonstrada com a simulação de zonas para conservação e recuperação, que representaram 34,4% da área da microbacia nas zonas de menor potencial de utilização agropecuária, em função da fragilidade de seus solos. Os resultados demonstraram que ganhos ambientais significativos podem ser obtidos com a aplicação da metodologia, proporcionando o aumento da conectividade entre os fragmentos remanescentes. Palavras-chave: Fragmentação; ecologia de paisagens; conservação da biodiversidade.   Abstract Methodology for planning fragmented landscapes aiming the creation of Ecological Corridors. The purpose of this study is to develop a planning methodology which makes analyses of the structure of a certain landscape possible, as well as its biotic and abiotic characteristics in order to elaborate an adequate land use planning. Moreover, the guidelines of this study were maintenance of hydric stability and increasing of connectivity in the watershed by identification of regions with great environmental fragility, considering hydrography, geomorphology, pedology, and remaining forest patches. In field survey, satellite image and aerial photographs were used. The watershed studied has 4,629.47 ha and is located near Iguaçu National Park on the third Paraná plateau. Several biotic and abiotic aspects were distinguished in order to simulate an adequate land use and to establish a biodiversity corridor. This method was validated by simulating conservation and recovery zones, which cover 34.4% of watershed area. Such zones represent low potential regarding crops and cattle raising due to their fragile soil. Results showed the applicability of the methodology used, reflecting environmental gains, providing the increasing of connectivity among remaining forest patches.

Energy Transitions

A transition toward decentralized and land-intensive renewable energy production systems is one among many factors re-shaping rural areas, leading to reimaginations and contestations. Especially in the Global North, the rural narrative now includes not just rural ‘production’ but also the ‘consumption’ of rural amenity and experience. Previous research into public attitudes toward renewable energy correlates the former with positive attitudes to renewable energy, and the latter with negative attitudes toward renewable energy. Territorial structures, such as official land-use plans, reflect dominant discourses and narratives that shape ongoing rural transformation. The purpose of this work is to understand the extent to which, if at all, those correlations at the individual level between landscape conceptualizations and sentiment toward renewable energy are manifest in territorial structures. In what ways are energy transitions present in rural land-use plans and planning systems? Is there a relationship between how rural landscapes are conceptualized and how energy transitions are framed and addressed, in land-use planning systems? These questions are answered through a structured content and discourse analysis of 10 land-use plans of rural municipalities in southern Ontario; an agriculturally intensive region that hosts much of Ontario’s large-scale renewable energy systems. Correlations observed between landscape conceptualizations and sentiment toward renewable energy observed are not strongly reflected in land-use plans. Land-use plans in this region are not positioned to manage the place-based opportunities and impacts associated with renewable energy development. The research reveals an opportunity for rural land-use planning systems to more explicitly incorporate energy transitions in their evolving discourses, identities and development trajectories.

Surveying And Mapping

In recording actual land use field-by-field or block-by-block methods can be applied either to detailed maps or to aerial photographs. In land-use mapping the usual scales are 1:25,000 for urban areas, 1:50,000 for densely settled areas with complex land-use patterns, and 1:250,000 for sparsely settled areas. In preparation of the map manuscript the base sheet used is of the material known as cronaflex and the transfer and reduction of information is achieved by use of the “reflex map reducer” a device invented by a geographer on the staff of the Geographical Branch.

The Mono Transboundary Biosphere Reserve (RBTM) has significant resources but faces many threats that lead to habitat fragmentation and reduction of ecosystem services. This study, based on satellite image analysis and processing, was carried out to establish the baseline of land cover and land use status and to analyze their dynamics over the period 1986 to 2015. The baseline of land cover established six categories of land use including wetlands (45.11%), mosaic crops/fallow (25.99%), savannas (17.04%), plantation (5.50%), agglomeration/bare soil (4.38%) and dense forest (1.98%). The analysis of land use dynamics showed a regression for wetlands (-23%), savannas (-16.06%) and dense forest (-7.60%). On the contrary, occupations such as mosaic crops/fallow land, urban agglomerations/bare soil and plantation increase in area estimated at respectively 128.64%, 93.94% and 45.23%. These results are of interest to stakeholders who assess decisions affecting the use of natural resources and provide environmental information essential for applications ranging from land-use planning, forest cover monitoring and the production of environmental statistics.Keywords: Land use, baseline, spatial dynamics, environmental statistics, ecological monitoring.
