Despite the large use of the travel cost method as estimation technique for the demand for forest recreation, information on price elasticity is only seldom reported. In this way, it is hard to understand if a large consumer surplus could be reflected in income opportunities for the local populations, because it is unknown whether the number of annual trips will decrease as a consequence of price changes. This is particularly relevant in remote rural areas, where few other opportunities for additional earnings are available. This contribution attempts to fill this gap, estimating price elasticities for two different specifications of the cost for travel; a first specification includes cost for travel only, while the second comprise on-site expenditures (such as food and accommodation). Data were collected by means of a questionnaire survey administrated to a sample of local visitors and analysed with a Poisson model. Results suggest that visitors have different sensitivities to distance travelled and to expenses locally sustained, the first being more elastic.

Complex organics are now commonly found in meteorites, comets, asteroids, planetary satellites, and interplanetary dust particles. The chemical composition and possible origin of these organics are presented. Specifically, we discuss the possible link between Solar System organics and the complex organics synthesized during the late stages of stellar evolution. Implications of extraterrestrial organics on the origin of life on Earth and the possibility of existence of primordial organics on Earth are also discussed.

This paper reports an analysis of the behavior and perception of migrant agricultural workers in relation to central human capacities. Seven dimensions of analysis were aligned to the human central capabilities proposed by Nussbaum. The results showed that physical health and emotions infringe human development of workers. The capabilities of practical reason, affiliation and control over the environment showed discrimination and social segregation. The results provide evidence on the quality of life and general welfare situation of migrant farm workers from a perspective for human development.

In this study, the food and nutritional energy requirements in Syria for the years of 2020,2030, 2040 and 2050 were calculated by assessing the demand and capacity of the country. The food requirement (ton/year) based on the various food sectors was calculated, which was used to determine the amount of food to feed Syria. For the enhancement of the food productivity, the shortcomings in the sector were identified. It was also aimed to provide a guidance on which basic steps should be taken during the rehabilitation period by assessing the agricultural and food self-sufficiency of Syria and help to develop a food policy for Syria’s future. According to the results, after the crisis/war in the future, the population of Syria will increase and reach to about 34 million in 2050. Syria will face with difficulties in feeding this expanding population, which is two-folds the current number. Additionally, climatic change will cause more arid region in Syria due to its geographical position, therefore it will depress the growth of food. Food security will also be another problem for Syria after the crisis/war.
