In Chad, some households and artisans continue to rely on wood and charcoal, which seriously degrades plant resources. In this context, household extension activities for improved stoves have been reinforced with low-energy types of stoves in certain localities located in the wood energy supply basin of the city of N'Djaména from 2003 to 2013 by the AEDE (Agency for Domestic Energy and the Environment). It is following this popularization of improved stoves that this study, which aims at the rational and sustainable use of wood resources, evaluated the consumption of wood energy in two categories: craftswomen of 'Bili-Bili' and craftsmen of 'Tchélé' in November 2016, in Mandelia. Data from forest inventories in the study area reviewed, as well as surveys among these targeted artisans, enabled the estimation of their wood energy consumption. The results show that the use of the 'Kiva-Base' improved stove adopted by 36% of the brewers resulted in a reduction of 62 kg/d/craftsman of 'Bili-Bili'; a 35% reduction in wood consumption. Among the 48% of meat grillers that adopted the 'Sewa' improved stove, a reduction in wood energy of 63 kg/d/craftsman of 'Tchélé' was recorded, representing a 30% reduction in wood consumption. This reduction in wood energy consumption represents a considerable positive impact on the conservation of wood resources in Mandelia. This work can be extended to other localities where the concentration of these craftsmen is higher for a sustainable management of wood energy. Au Tchad, certains ménages et les artisans continuent par s’approvisionner en bois et charbon de bois ; ce qui dégradent sérieusement les ressources végétales. Dans ce contexte, des actions de vulgarisation des foyers améliorés dans les ménages ont été renforcées avec des types de foyers à basse consommation d’énergie dans certaines localités situées dans le bassin d’approvisionnent en bois-énergie de la ville de N’Djaména de 2003 à 2013 par l’AEDE (Agence pour l’Energie Domestique et l’Environnement). C’est à la suite de cette vulgarisation des foyers améliorés que cette étude qui vise l’utilisation rationnelle et durable de ressources ligneuses a évalué la consommation en bois-énergie chez deux catégories : artisans de ‘Bili-Bili’ et artisans de ‘Tchélé’ en novembre 2016, à Mandelia. Les données sur les inventaires forestiers de la zone d’étude passées en revue ainsi que des enquêtes chez ces artisans ciblés ont permis d’estimer leur consommation en bois-énergie. Les résultats montrent que l’utilisation du foyer amélioré de type ‘Kiva-Base’ adopté par 36% des brasseuses a permis de réduire 62 kg/j/artisan de ‘Bili-Bili’; soit une réduction de 35% en consommation de bois. Chez les 48% des grilleurs de viande qui ont adopté le foyer amélioré de type ‘Sewa’, une réduction en bois-énergie de 63 kg/j/artisan de ‘Tchélé’ a été enregistrée ; soit une réduction de 30% en consommation de bois. Cette réduction de consommation en bois-énergie représente un impact positif considérable sur la conservation des ressources ligneuses à Mandelia. Ce travail peut être étendu à d’autres localités où la concentration de ces artisans est plus élevée pour une gestion durable en bois-énergie.

Non Timber Forest Products

Non-timber Forest Products (NTFPs) play an important role as traditional source for food, fiber, fodder, and medicine and offer income opportunities for poverty alleviation especially in rural households in Nepal who engage in a widespread trade of NTFPs. Adequate planning for sustainable use of NTFPs is imperative so we explored the inventory of multipurpose trees and herbs that are being used as NTFPs in Chitwan, Nepal. 70 households from Sukranagar and Mangalpur VDCs of Chitwan district were randomly selected and personal interviews were taken with them as well as focus group discussions were done. The community had been utilizing 49 plant species from the nearby community forest. Implementation of the policy of community forestry was found to have a positive impact on the sustainable production of NTFPs. More than 80% of the respondents believed that indigenous knowledge promoted sustainable NTFP production. Kurilo (Asparagus officinalis) was found to be the best NTFP for the study site. Various policy level reforms are proposed that will help in improving the sustainable production of NTFPs. Better utilization of NTFPs as well as their conservation is possible with proper trainings given to community forest users.International Journal of Environment Vol.5(3) 2016, pp.87-103

This paper studies the use of bipolar-particles-electrodes in the decolorization of dyeing effluents. Treatment of highly colored solutions of various soluble dyes (such as direct, reactive, cationic or acid dyes) and also samples of dyeing effluents gave rise to an almost colorless transparent liquid, with removal of CODcr and BOD5 being as high as over 80%. The method is characterized by its high efficiency, low energy consumption and long performance life. A discussion of the underlying principle is given.

Recent market studies show that the market for remote monitoring devices of different medical parameters will grow exponentially. Globally, more than 4 million individuals will be monitored remotely from the perspective of different health parameters by 2023. Of particular importance is the way of remote transmission of the information acquired from the medical sensors. At this time, there are several methods such as Bluetooth, WI-FI, or other wireless communication interfaces. Recently, the communication based on LoRa (Long Range) technology has had an explosive development that allows the transmission of information over long distances with low energy consumption. The implementation of the IoT (Internet of Things) applications using LoRa devices based on open Long Range Wide-Area Network (LoRaWAN) protocol for long distances with low energy consumption can also be used in the medical field. Therefore, in this paper, we proposed and developed a long-distance communication architecture for medical devices based on the LoRaWAN protocol that allows data communications over a distance of more than 10 km.

In the literature, very few studies have focused on how urbanisation will influence the policy effects of a climate policy even though urbanisation does have profound socioeconomic impacts. This paper has explored the interrelations among the urbanisation, carbon emissions, GDP, and energy consumption in China using the autoregressive distributed lag (ARDL) model. Then, the unit urbanisation impacts are inputted into the policy evaluation framework of the Computable General Equilibrium (CGE) model in 2015–2030. The results show that the urbanisation had a positive impact on the GDP but a negative impact on the carbon emissions in 1980–2014. These impacts were statistically significant, but its impact on the energy consumption was not statistically significant. In 2015–2030, the urbanisation will have negative impacts on the carbon emissions and intensity. It will decrease the GDP and the household welfare under the carbon tax. The urbanisation will increase the average social cost of carbon (ASCC). Hence, the urbanisation will reinforce the policy effects of the carbon tax on the emissions and welfare.

Task Offloading

AbstractWith the developing of Internet of Things (IoT) and mobile edge computing (MEC), more and more sensing devices are widely deployed in the smart city. These sensing devices generate various kinds of tasks, which need to be sent to cloud to process. Usually, the sensing devices do not equip with wireless modules, because it is neither economical nor energy saving. Thus, it is a challenging problem to find a way to offload tasks for sensing devices. However, many vehicles are moving around the city, which can communicate with sensing devices in an effective and low-cost way. In this paper, we propose a computation offloading scheme through mobile vehicles in IoT-edge-cloud network. The sensing devices generate tasks and transmit the tasks to vehicles, then the vehicles decide to compute the tasks in the local vehicle, MEC server or cloud center. The computation offloading decision is made based on the utility function of the energy consumption and transmission delay, and the deep reinforcement learning technique is adopted to make decisions. Our proposed method can make full use of the existing infrastructures to implement the task offloading of sensing devices, the experimental results show that our proposed solution can achieve the maximum reward and decrease delay.
