In 2000, Mexico’s National Commission of Protected Areas (CONANP) was created to encourage the protection, management and restoration of natural and cultural resources and their conservation. Protected areas were recently increased by more than 3 million hectares, for a current total of more than 25 million hectares, corresponding to 174 protected areas that cover 12.90% of the country’s surfac...

The use of Unmanned Aircraft System (UAS) in remote sensing works is becoming a reality. In forest fire scenarios we propose the use of UAS for semi-real-time hot spot detection. In this paper we present Sky-Eye, a rotorcraft prototype designed to provide significant advantages in terms of flexibility, precision, cost, and safety. Sky-Eye is specifically designed for Mediterranean forest fires,...

[1] Land-cover changes in China are being powered by demand for food for its growing population and by the nation’s transition from a largely rural society to one in which more than half of its people are expected to live in cities within two decades. Here we use an analysis of remotely sensed data gathered between 1990 and 2000, to map the magnitude and pattern of changes such as the conversio...

Wind energy offers the potential to reduce carbon emissions while increasing energy independence and bolstering economic development. However, wind energy has a larger land footprint per Gigawatt (GW) than most other forms of energy production, making appropriate siting and mitigation particularly important. Species that require large unfragmented habitats and those known to avoid vertical stru...

Recently, there has been a massive drying of conifers all over the world. In North America and Siberia, are millions hectares shrunken plantings; in Europe, pines firs have up past two decades. Furthermore, considerable damage is caused to woody plants by phyto-pest phyto-diseases, since mass reproduction Ips typographus Linnaeus, acuminatus Gyllenhal observed Europe recent years, Dendroctonus ...

During the 1850s, the amount of farmland in the United States increased by 40 million hectares (100 million acres), or more than one-third. Moreover, almost 20 million hectares, an area almost equal to that of the states of Indiana and Ohio combined, were converted from their raw, natural state into productive farmland. e time and expense of transforming this land into a productive agricultural...

Forest and forest product certification systems have grown rapidly in recent years, developing in parallel with the many international, national, and regional initiatives attempting to define and promote sustainable forest management (SF M ) (C arbarle et al. 1995, L awes et al. 1999). T he area certified under the most widely adopted international system, the Forest Stewardship C ouncil, is no...

The productive cellulosic crops switchgrass and Miscanthus are considered as viable biofuel sources. To meet the 2022 national biofuel target mandate, actions must be taken, e.g., maize cultivation must be intensified and expanded, and other biofuel crops (switchgrass and Miscanthus) must be cultivated. This raises questions on the use efficiencies of land and water; to date, the demand on thes...

The valley of the Peene River is located in the northeast of Germany in eastern Mecklenburg-Vorpommern. The whole area includes about 35.000 hectares. Out of these 20.000 hectares are nature protection areas. The Peene is one of the last unspoilt rivers in Germany and one of the biggest linked fens in Europe. It is held as very precious and from all river valley fens as best preserved. In this ...

Indonesia has a huge potential of mangrove resources. In 2010, the mangrove area was 5,209,543.16 hectares and the area was decline rapidly to 2,496,185 hectares in 2016. This figure shows depletion and degradation of mangrove ecosystem and therefore, the capacities to supply human needs are decline because of the intense pressure from many activities in the development of coastal zone. The dat...
