This paper aims to present renewable air-conditioning as a sustainable system for varied climatic conditions with the feasibility of optimization to reduce the level of energy consumption and the rate of carbon emissions. Extreme use of air-conditioning has caused substantial growth in the level of energy consumption and carbon emissions. This fact clarifies the requirement for considering improvement applications of renewable energy sources for air-conditioning systems. The components of solar air-conditioning are studied and employed as the basis for system optimization. The approach this paper presented implements a key component-based modelling analysis of renewables and modelling concepts that the geometry of this air-conditioning is founded on. The optimized model is performed using Polysun program, a renewable system analysis tool. As an exercise in the system modelling, the principle component analysis also accounts for the renewables of air-conditioning in relation to the context of the application and with respect to their integration into the climatic conditions of London, Toulouse and Rome. This, in turn, allows for the interpretation of the findings on the significance of renewables in energy consumption and carbon emissions. It also allows for the generation of a sustainability-based system that can reduce the level of energy consumption and the rate of carbon emissions. In this way, this paper uncovers the significance of renewables as a source of clean energy and sustainable practice in air-conditioning. It also reveals the particular contribution they make to the levels of energy consumption and carbon emissions that not only tackles global warming but also combats climate change.

This study deals with the managerial competencies of current managers that are required to achieve sustainable development projects. A comparative literature review is conducted to summarize the critical managerial competencies in general. Then, this is narrowed down to find the managerial competencies that lead to the proper accomplishment of sustainable development projects. Considering these views, the purpose of this exploration is to discover the significance of managerial competencies on the achievement of sustainable development projects. The findings indicate that communication, leadership, development orientation, achievement orientation, motivation, teamwork, innovation, and decision making are the most critical managerial competencies that can enhance the performance of managers towards achieving sustainable development projects. Thus, this article demonstrates a model inclusively for managers to link the found managerial competencies with the realization of sustainable development projects. The model is focused mainly on the specific managerial competencies that will encourage managers to perform outstanding results in recent as well as future sustainable development projects.

Forests in Kenya were under traditional community management regimes up to 1891 when formal state management of forests started in Vanga Mangrove forest and later the entire country. In 1997 decentralized forest governance was successfully piloted through Participatory Forest Management in Kenya. This informed review of the Forests Act, Cap 385 to The Forests Act, 2005 subsequently revised to Forest Conservation and Management Act, 2016. The Act has explicit support to decentralized forest management with special focus on communities. The study determined the perceptions of policy makers on: why decentralization was introduced; policy makers’ understanding of decentralization and its impact on forest management and community livelihoods. Literature review was conducted, questionnaires administered and Key Informant Interview and Focus Group Discussion held. The policy makers indicated that decentralization was being implemented in the country and they could distinguish the models being practiced and noted that decentralization was facilitating stakeholder participation and improving forest conservation and community livelihoods. The key challenges were; inadequate budgetary allocation; failure by state to transfer key functions to communities but had decentralized roles that reduce costs. The country has three forest management models and each was best in its context but can be enhanced through capacity building, financial support and partnerships.

Upon an improvement in the quality of life, air-conditioning has generally been applied. Nevertheless, environmental and health issues related with the use of air-conditioning occurs more often. Therefore, this paper aims to theoretically assess the principles of sustainability to achieve sustainability for renewable smart air-conditioning. Not only with consideration to the geometry (i.e. system mechanisms and components), fuzzy logic control and proportional-integral-derivative that such studies drawn particular attention to, but with concerns to a matter which has been previously ignored. That is with consideration to the potential which the renewable-based options, advanced smart control technique and profitability measures of air-conditioning reinforces the three pillars of sustainability, and their sustainable indicators as context-specific transformations have, to not only eradicate indoor health effects, lower the levels of energy consumption and rate of carbon emissions, but to uncover the significance of and particular contribution renewables and smart control opportunities makes to the sustainability of the system. In meeting this aim and demonstrating the sustainability of the theoretical framework, this paper reveals renewable and smart control system as the fundamental key components of the air-conditioning as it promotes to reduce levels of energy consumption and lower carbon emissions, vis-a-vis establish a comfortable and healthy indoor environment as an exercise in the sustainable theoretical framework whose status as renewable smart air-conditioning not only tackle poor indoor air quality but also combat global warming and climate change.

Using the Modified Taungya System (MTS) to establish plantations has been identified as one of the important strategies required to meet the demand for wood resources in Ghana. The MTS is a forest management approach in which farmers are given lands within degraded forest reserves to inter-plant food crops with trees, and further nurture the trees into maturity under specified roles and benefit sharing agreements. This study evaluated the MTSs and management approach based on the following sustainability criteria: recognition of gender role in agroforestry development, contribution of the systems to poverty reduction, and contribution of the systems to the improvement in productive and protective functions of agriculture. The systems were established in degraded portions of the Pamu-Berekum Forest Reserve, Ghana in 2000. Data were collected in 2016 through personal interviews of 40 farmers selected from three communities living close and around the forest reserve. It is clear from the result that women participation in the project activities is significant and may have contributed to the reported successful outcome. More than a decade after the establishment of these plantations, there is evidence that the non-timber forest products, (e.g. fuelwood, medicine) generated from practising MTS have had a significant impact on the community livelihood with significant changes in annual income. Also, the farms clearly have many trees surviving that have economic, social, and ecological significance. The MTS, indeed, has the potential to support biodiversity recovery within degraded forest reserves in Ghana as well as to improve the livelihoods of farmers.

This paper sought to assess the role of artisanal and small-scale mining in poverty alleviation, focusing on Barn mining area ward 25 Matopo (Matabeleland South Province). The study adopted a mixed method approach in data collection, comprising the use of questionnaires, interview guides, observation tools and focus group discussions. The study found that ASM contributes to income generation and employment creation and has become a major source of livelihood in many mineral resource endowed areas of Zimbabwe. It was concluded that ASM as an economic activity has improved livelihoods as the income affords the miners an improved standard of life in addition to the ability to buy agricultural inputs and sending their children to school. However, several challenges associated with ASM were identified. These include lack of financial and institutional assistance, gold wars and other unfound agreements made between miners and claim owners. Loss of life in mine accidents, spread of sexually transmitted diseases are some of the negative impacts identified. The study recommended that for the benefits of ASM to be realised in terms of poverty alleviation, ASM activities should be decriminalized and financial support availed to miners.

Based on a year-round data-set (from January to November 2014), an intensive air sampling program was conducted during 2014 in four different function sites in South El-Tabbin city to study the temporally and spatially characteristics of Poly Aromatic Hydrocarbons (PAHs) in the gaseous and particulate phases. This area is considered as one of the most polluted areas in Egypt as it includes heavy industrial plants, as well as it is bounded by heavy traffic. A total of 48 atmospheric samples were collected by a high-volume active air sampler. The gaseous and particulate phases of PAHs were extracted and analyzed using Gas chromatography/mass spectrometry together. The total concentrations of the sixteen PAHs (which tagged the United States Environmental Protection Agency priority) in the air of the study area ranged from 76.48 ± 19.44 µg/m 3 to 26995.86 ± 2835.91 µg/m 3 . The average PAHs concentration in the coke production site was ~ 355 times of that in the residential area site. For the whole study area; 4, 5, and 6 rings PAHs were dominant and accounting for ~66% – ~84%. The total concentrations of combustion derived PAHs were ranged from 63.24 ± 17.35 µg/m 3 to 17546.97 ± 1848.55 µg/m 3 covering 65% − 83% of total PAHs which indicating large amounts of combustion sources existed from them in South El-Tabbin city. Seasonal trends of PAHs concentrations were observed with a high concentration in winter and low in summer where the average concentration of PAHs in winter was ~1.6 times higher than that in summer.

Ica Aquifer located at the coastal zone of Ica River Valley, supplies 40% of the water to a number of farms of Ica Region which is one of the most productive valley of Peru that covers an area of 30,000 hectares of area, in which a diverse agricultural product are grown for local and external market. In the last 15 years, water-table of the aquifer was lowering at an elevated rate that concerned to farmers and authorities of the Peruvian Government, so a number of studies was carried out to increase the water supply to the agriculture areas. The main purpose of the study using isotope techniques, was to have a first insight of the hydrodynamics of Ica, Villacuri and Lanchas Aquifers and the possible interconnection between them and with Pisco River. For such purpose, 31 wells, lakes, rivers and springs of Ica and Pisco Basin where sampled during the years 2014 to 2016 both in rain and dry seasons, getting 189 samples for isotope and chemical analysis. The sampling schedule didn’t include rain sampling, instead of it, selected springs were sampled and nearby basin rain data was used. 18 O, 2 H and 13 C stable isotopes and 3 H, 14 C radioactive isotopes of the water samples were analyzed in the laboratory of “Isotope Tracer Technologies INC”; the results of the stable isotope analysis confirm the hydraulic interconnection of the three aquifers mentioned above; it also was confirmed that the main source of recharge was provided by Ica River and evidences were found about the contribution of Pisco River in the recharge of Villacuri and Lanchas Aquifers. Analysis of 14 C reveals that some wells are overexploited. All the results of 3 H analysis were out of range, so it was not useful for the conclusions of the study, and a new sampling of water is required; the reason of this out of range result should be the possible contamination of the samples with no environmental Tritium.

There has been a long-standing demand on businesses to play an increasingly larger role in sustainable development. This demand is for issues that contribute to the creation of a sustainable world; ranging from poverty alleviation to climate change. The United Nations’ Sustainable Development Goals (SDGs) were unanimously adopted by 193 UN member states in September 2015 and calls upon the central and diverse role that the private sector can play to deliver on the SDGs during the 15-year period, 2016-2030. This paper has two major contributions: First, it analyzes member companies of Business Call to Action (BCtA), an international initiative launched at the United Nations in 2008, to identify SDGs that are most impacted by the private sector. Second, the global analysis draws attention to the role of the private sector in addressing the sustainability challenges in five geographical regions of the world, through their contributions to the SDGs. Using the ‘five Ps’ framework, the results show that some SDGs are more impacted than others, thereby implying that these SDGs will substantially benefit from the success of the private sector while others could be left behind. The findings provide practical recommendations for businesses and stakeholders to use BCtA members as role models to integrate specific SDGs into their business activities and thereby contribute to the achievement of the SDGs.

PPPs in Sri Lanka are filling a regulatory gap resulting from withdrawal of government from the management of forest resources. The national forest policy has emphasized afforestation, conservation and protection as the main components of emerged government-community, donor–recipient and public–private partnerships with local people, rural communities and other stakeholders. Timber and fuel-wood plantations, and agro-forestry woodlots have been established through partnerships. Eco-tourism has been given special emphasis through partnerships between the government agencies, private sector and communities. Private sector involves in forestry as a business through sustainable agro-forestry, imparting financial gain. The government has identified risk mitigation as an integral part of the government–community partnership planning process. Investments of private sector in forest management are committed to enhance inflow of foreign exchange earnings through the export of value added forest products. The Forest Ordinance has empowered Forest Department for the management, protection and development of forest resources. PPPs are far less frequent in rule-setting and implementation of timber and fuel-wood plantations and agro-forestry woodlots. Work undertaken by community based organizations in PPPs occurs on a minor scale. Private-sector involvement in forest resources management has raised serious concerns by public perception about conflict of interest. The Government needs serious efforts and amendment of forest policies to promote public-private partnerships for the sustainable development of forest resources.
