Poland, which biological diversity stands out in comparison with the rest of Europe, became one of the biggest road construction site during the last few years. A development of a road network almost always involves disturbance of biogically sensitive and protected areas. As those areas cover about one third of the whole country it is virtually impossible to avoid conflicts concerning biological protection. For those reasons, steps to be taken to limit to a minimum the incidence of the construction works on the biological environment constitute an integral part of each investment. The costs of protecting unspoiled environment represent up to 30% of the total costs of investments. The effectiveness of planned actions must consequently justify spending the considerable funds involved. Monitoring of the results of solutions used allows both verification of their usefulness and identification possible errors so that they may be avoided in the future. Number of actions which have been undertaken in Poland to minimalize the incidence of roads on unspoiled environment, in particular as regards the number of fauna passes, to preserve the ecological continuity, place Poland among most advanced European countries.

Protected Areas (PAs) are created for the protection and maintenance of biological diversity, but many of Ghana’s PAs are subjectto severe pressures and threats, the main pressures being the illegal extraction of natural resources. Rattans are indisputablyone of the most important Non-Timber Forest Products (NTFPs) in Ghana’s Protected Areas that is without doubt one of thereasons for which it has drawn the attention of researchers. In this study the illegal rattan extraction patterns in the AnkasaConservation Area (ACA) in Ghana was inspected. Simple random sampling and Snowball sampling techniques were used. Datacollection employed the use of semi-structured questionnaires, interviews and field enumeration of rattans as well as an analysisof Effective Patrol Man-days (EPMDS) from 2004 to 2012. The results showed a significant positive correlation (r = 0.75, p<0.05, r2 = 0.557) between patrol effort and rattan extraction encounters. In addition, there was a general reduction in illegalrattan extraction encounters from 2004 to 2012 at a rate of 4.3 per year. The highest illegal rattan extraction incidences wererecorded in 2006 (76 encounters), 2005 (35 encounters), 2008 (22 encounters), 2004 (18 encounters) and the least incidencewere recorded in both 2010 (3 encounters) and 2011 (3 encounters).The research also revealed that Eremospatha macrocarpawas the most extracted rattan species followed by Laccosperma secundiflorum. The major rattan extraction and trade routesoriginate in the northern parts and in the area east of the reserve and also south of Draw River Forest Reserve. Generally, rattanpoaching in Ankasa Conservation Area has declined, but there are still human incursions in the northern part of the reserve. Thestudy recommended an intensification of patrols in the north of the reserve. Also, enrichment planting and Agroforestry practicesof inter-cropping rattans with seasonal crops should be pursued vigorously for the local communities.

AbstractI address a contentious element in forest property relations to illustrate the role of ownership in protecting and expanding of forest cover by examining the extent to which rural communities may legally own forests. The premise is that whilst state-owned protected areas have contributed enormously to forest survival, this has been insufficiently successful to justify the mass dispossession of customary land-owning communities this has entailed. Further, I argue that state co-option of community lands is unwarranted. Rural communities on all continents ably demonstrate the will and capacity to conserve forests – provided their customary ownership is legally recognized. I explore the property rights reforms now enabling this. The replication potential of community protected forestlands is great enough to deserve flagship status in global commitments to expand forest including in the upcoming new Convention on Biological Diversity (CBD).

The golden age of road demand modeling began in the 1950s and flourished in the 1960s in the face of major road construction needs. These macro models, as well as the econometrics and the data to be processed, were provided mainly by engineers. A division of tasks can be observed between the engineers in charge of estimating the flows within the network and the transport economists in charge of managing these flows once they are on the road network. Yet the inability to explain their decision-making processes and individual drives gave some room to economists to introduce economic analysis, so as to better understand individual or collective decisions between transport alternatives. Economists, in particular Daniel McFadden, began to offer methods to improve the measure of utility linked to transport and to inform the engineering approach. This paper explores the challenges to the boundaries between economics and engineering in road demand analysis.

In many developing cities, the improvement of transport infrastructure is usually accompanied by major road construction and maintenance. This paper presents approaches and opportunities using peer-to-peer updating to improve spatial road networks undergoing construction and maintenance, which in turn will improve traffic flow and benefit cities overall. In many cities, the spatial road network requires maintenance, and these works often require traffic detours. With the current GPS (Global Positioning System) services, there is a noticeable delay in the updating of many spatial road networks. Thus, when a driver plans a trip to a certain location (such as Starbucks), his/her usual route may have changed, but the spatial road network in the GPS has not been updated. This can affect the user in many ways. For example, a trip that usually takes five minutes might now take half an hour, taking into account the additional time required to find alternative roads and possibly encountering more unexpected road closures, until the driver reaches his/her destination. This paper addresses this issue by proposing solutions that offer several advantages including a new peer-to-peer updating mechanism that helps to direct the driver to another route when road changes occur. Moreover, the peer-to-peer updating mechanism can enable the independent monitoring of road conditions and the updating of maps for newly-constructed roads, as well as the analysis of road congestions, traffic density, and people movements at certain times. Note that this work focuses on the conceptual ideas and approaches intended to improve independent maps, and the detailed algorithms have been left for future work.

After the conquest of the Bosnian and Herzegovinian territory, the Romans  launched numerous campaigns so this region and its population could be incorporated into the Roman life and Roman civilization of that period as quickly as possible. They believed that this is the only and the best way to make themselves the masters of this region. As part of their extensive activities, those that focused on systematic and full implementation of urbanization in the present-day Bosnia and Herzegovina were especially important. This long process encompassed the infrastructure construction, modelled on the Italic cities, villages, economic and other facilities. The first steps of the Roman authorities were to construct modern and high-quality roads, i.e. a powerful road network that would facilitate a faster and stronger connection between settlements and economic resources around present-day Bosnia and Herzegovina. Publius Cornelius Dolabella, who served as an imperial governor of the province of Upper Illyria from 14 th  to 20  AD, had a special role in the implementation of this plan. The construction of the first roads began upon his initiative and under his strict supervision. He intended to establish a better connection between the regions of present-day Bosnia and Herzegovina with the eastern coast of the Adriatic Sea. These first roads created good foundation for a complete urbanization of this area. th Along with the road construction, the Romans launched the activities that included new settlements, firstly along the Roman roads, then at the crossroads, and then in the regions had were rich in resources. Each settlement, in its appearance, dimensions and layout of facilities and its infrastructure, had to correspond to the Roman building standards. The first settlements were built along the roads. The most famous sites of urban settlements include: Grkovci and Pelva (Livno plateau), Halapići and Salvium (Glamoč plateau), Pecka (the Sana river valley), Baloie (Šipovo), Bjelajac (Mrkonjić Grad), Castra, Laktaši, Gornji Šeher (Banja Luka), Servitium (Bosanska Gradiška), Delminium (Duvno plateau), Varvara (Rama river valley), Ad Matricem (Gornji Vakuf), Bistue Nova (Bugojno), Višnjica (Kiseljak), Ilidža (Sarajevo plateau), Domavia and Skelani (central Podrinje), Blagaj, Maslovare and Bosanski Novi (the Sana and Japra rivers valley), Golubić (Bihać), Bigeste (Čapljina), Leusinium (Bileća), Diluntum (Stolac), Ad Drinum (Drinjača) as well as many others, but less known.  Urbanization had many positive effects in all aspects of work and life of local inhabitants from that period in the region of present-day Bosnia and Herzegovina. A road network was established, as well as numerous economic activities, lifestyle standard and social relations were raised to a significantly higher level, many settlements (cities and villages) and many cultural monuments were built.

Mangroves are valuable socio-ecological ecosystems that provide vital goods and services to millions of people, including wood, a renewable natural capital, which is the primary source of energy and construction material for several coastal communities in developing countries. Unfortunately, mangrove loss and degradation occur at alarming rates. Regardless of the protection and close monitoring of mangrove ecosystems in Mexico during the last two decades, mangrove degradation and the loss of biodiversity is still ongoing. In some regions, unregulated and unsustainable mangrove wood harvesting are important causes of degradation. In this context, community-based mangrove forestry through Management Units for Wildlife Conservation could be a cost-effective alternative scheme to manage and conserve mangrove forests, their ecosystem services and biological diversity within and beyond protected areas while providing sustainable local livelihoods and helping reduce illegal logging. The objective of the Management Units is to promote alternative means of production with the rational and planned use of renewable resources based on Management Plans. If implemented with a multidisciplinary perspective that incorporates scientific assessments this conservation strategy may contribute to achieving national and international environmental and biodiversity agreements providing multiple social, ecological and economic benefits from local to global scales.
