Wild foods contribute to the food security of multiple communities in tropical areas of Africa, Asia and Latin America. However, wild foods are not regularly considered in the planning of strategies for food and nutrition security mainly due to the lack of technical and/or scientific knowledge so that they can be considered suitable for human consu...
Monitoring of land use, land-use changes, and forestry (LULUCF) plays a crucial role in biodiversity and global environmental challenges. In 2015, the Food and Agriculture Organization of the United Nations (FAO) launched the Global Forest Survey (GFS) integrating medium- (MR) and very-high-resolution (VHR) images through the FAO’s Collect Earth pl...
The global distribution of forest trees is essential for monitoring land-use sustainability. For this reason, FAO developed the Global Forest Survey (GFS), a systematic regional level survey with a homogeneous sampling design. Preliminary results revealed an interest in analyzing “Trees Outside Forests” (TOFs). We analyzed more than 11,150 sample G...
Recent increases in incidents make it unlikely for emergency systems to be able to meet incident requirements. In this paper, we formulate a new territorial measurement approach for the reliability of fire departments, the collapse index, to help decision makers determine their response capability. This new index expresses the maximum simultaneous...
Rapid urban growth has historically led to changes in land use patterns and the degradation of natural resources and the urban environment. Uncontrolled growth of urban areas in the city of Quito has continued to the present day since 1960s, aggravated by illegal or irregular new settlements. The main objective of this paper is to generate spatial...
Traditional consumption of plants, fungi and wild animals constitutes a reality for the feeding of diverse human groups in different tropical territories of the world. In this regard, there are two views within the academic community: (1) those who defend the importance of the traditional consumption for family food security in rural areas, especia...
Sclerophyllous forests are extremely sensitive to global warming, and the sclerophyllous forest in the possession of small forest landowners (SFLs) in the Libertador General Bernardo O’Higgins Region in Chile is degraded in spite of their high ecological value. Due to the total lack of forest management, the yield obtained from native forests is ve...

The use of public goods by authorities that rule a region with administrative limits is one of the problems faced by societies, including the rural ones. A network of rural roads is an example of goods with scarce maintenance by the authorities, which is also the way for the flow of goods and services. Its good state and maintenance is a factor tha...
It is postulated that communities using social learning on rural planning will achieve sustainable development. The construction of roads integrates geographic spaces and it is a requirement for competitiveness and development of the communities. In Mexico, the construction of roads and its improvement use existing ways originated by the transfer o...
The mean and standard deviation (SD) of light detection and ranging (LiDAR)-derived canopy height are related to forest structure. However, LiDAR data typically cover a limited area and have a high economic cost compared with satellite optical imagery. Optical images may be required to extrapolate LiDAR height measurements across a broad landscape....

The influx of a large number of women into the workforce involves the need for these women to combine family and work responsibilities. Multiple roles lead to work–family conflict. This study analyzes the influence of work–family conflict on the causes of minor occupational accidents suffered by working women. A survey was done on working women in...
The natural harvesting and cultivation of Tuber melanosporum (black truffle of Périgord) has spread throughout many countries in recent decades. Other black truffles such as T. aestivum, T. brumale, and T. mesentericum cause damage to T. melanosporum exploitation. These truffle species have been found to be very much present in the mycorrhizal cont...
Combination of various data sources has been demonstrated more effective than using them separately. Information retrieval is significantly improved by synergies between laser scanner and optical imagery. Digital photography relies on traditional methods for orthorectification in order to accomplish an accurate correspondence with Lidar. We investi...
In this paper, we present a two-stage approach for characterizing the structure of Pinus sylvestris L. stands in forests of central Spain. The first stage was to delimit forest stands using eCognition and a digital canopy height model (DCHM) derived from lidar data. The polygons were then clustered (k-means algorithm) into forest structure types ba...
The relationship between competition and tree growth was studied in four stands of Pinus sylvestris L. occurring in a continental Mediterranean mountain area (in the Guadarrama range, Spain), i.e., an uneven-aged stand, a stand with oak (Quercus pyrenaica Willd.) understorey, a plantation, and a mature even-aged stand. Competition was measured by a...
The evolution of the active agrarian population (AAP) in Spain has been in descent since the 1960's, which is similar to what has occurred in the other countries of the European Union. In Spain, this decrease in the AAP has been very rapid; in 1976, it represented 25% of the total active population, but in 2004 it was only 7%. This process occurs i...
In Mediterranean pine forests, truffles and mushrooms generate greater profits than any other woodland products. However,
there are no studies on Tuber melanosporum Vittad. associated with pines. For this reason, we have carried out a study of this truffle in mountain woods with Pinus sylvestris L. and P. nigra Arnold subsp. salzmannii (Dunal) Fran...
