Despite the fact that soil organic N has been long admitted for its importance to maintain soil fertility. Presented field experiment was conducted in Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute (ICCRI), Jember, East Java, Indonesia, to investigate the effect of cocoa farm management, namely fertilization, weeding and soil tillage on the content of soil organic N fractions. The design of experiment was arranged in a split-split plot with two levels of weeding as main plots, two levels of soil tillage as subplot and three different fertilizer treatments as sub-sub plot. The analysis of soil N including total N and soil organic N fractions, namely, total hydrolized N, ammonium N, amino sugar N and amino acid N, were performed. The result showed that the effect of fertilization treatment was significant to the content of total N, ammonium N, amino sugar N and amino acid N. No-tillage treatment resulted in total N and amino sugar-N content increasing by 8% and 24%, respectively, over tillage treatment. Slashing treatment caused increase of the total N by 3% from herbicide treatment, whilst decrease of ammonium N and amino sugar N by 7% and 24%, respectively.展开更多

Upon tourism's being considered as a serious development strategy in the developments of the countries, all the countries of the world have begun to accelerate their investments in this area through utilizing the natural and cultural assets of their countries (heritage) with a view to provide revenue to their economy as well as creation of jobs. This situation, which has emerged as a result of the globalization of supply and demand in tourism, has created certain problems in terms of environmental balance and the living conditions of local people as a result of poor management of the utilization of natural and cultural resources. The objective of this paper is to examine the concepts and principles germane to sustainable tourism which has significant contribution to the development of the countries, made at the macro level both in the world and in Turkey. The aim of this paper, at the micro level, is to create awareness incident to the tourism resources of the Van Region and the Old Van province and ensure the utilization of these resources through protection thereof. At the end of the study, the importance of the protection of heritage resources as well as fair use thereof in terms of increasing the competitiveness of Turkey on a global scale in tourism is addressed in the light of the overall evaluations.展开更多

Today, there is an increasing need for sustainable building design. Besides, BIM (building information modeling) is one of the most noteworthy developments in construction industry. BIM is used to make the planning, design, construction, and operation process more integrated. The purpose of this paper is to survey application of BIM in sustainable building design. This exploration is done by reviewing the existing studies in the field of BIM and sustainable design. There have been few attempts to evaluate and analyze the benefits of BIM in sustainable design, and existing researches have not developed integrated analysis to evaluate different aspects of BIM application. In this study, BIM and sustainable design researches are categorized into some major areas. First, frameworks and design strategies for better implementation of sustainable design have been developed. Other application of BIM software is for improving sustainable design in which some case studies have been presented for this purpose. Another major area is focusing on a specific aspect of sustainable buildings such as using natural resources, energy simulation, daylighting analysis and carbon emissions. Scrutiny review of the current studies shows excellent potential for interaction of BIM with sustainable construction.展开更多

However, this development relates to natural resources depletion and deterioration of quality of life in rural population, especially in smallholder farmers. Thailand has practiced the New Theory Agriculture (NTA), one application aligned with sufficient economy. This theory not only remedies damaged natural resources but also helps smallholder farmers to improve quality of life; and it is analogous to local food supply chain theory, that is well-known in western countries. However, NTA has not been measured its sustainability. Following sustainable food criteria and sustainable agriculture criteria, this paper uses an Indicator of Sustainable Agricultural Practice (ISAP) to measure sustainability at farm level of small rural community's network called Inpaeng, a case study that has practiced NTA. The result of assessment in this case implies that NTA yields sustainability to local food supply chain more than monocrop system.展开更多

This fishery is an important one in the region, but is threatened by increasing over-exploitation which has led to a steady decrease in the production. In addition to over-exploitation problem, a record of tsunami disaster makes this fishery a unique case. This research, based on a set of primary and secondary data was carried out using the Rapfish analytical approach. Primary data were collected using a stratified cluster random sampling technique, where as many as 186 outboard fishing operators were selected. Meanwhile, relevant complementary data were solicited purposively from five employees of Pangandaran Marine and Fisheries Service. Following from the Rapfish approach, it was found through this research that sustainability levels of fisheries in Pangandaran fall into poor category. For all types of fisheries that exist in the region, almost all sustainability dimensions namely ecological, social, technological and ethical dimensions were scored below 50 of the 100 maximum values. This paper concludes with a suggestion, pointing out attributes that should receive government attention in order that the sustainability of the fisheries in the future.展开更多

There is also an unpredictable pattern of use of labour in cocoa farms. This has a negative implication on the level and quality of farm output among small holder farmers. The study investigated the effects of labour use patterns on productivity of cocoa farms in south western Nigeria. Multi-stage random sampling technique was used to select the respondents and the data were analyzed with the use of descriptive statistics and stochastic efficiency frontier function. Many farms (80%) were less than 5 hectares in size and sharecropping was the most dominant of the labour types on the farms. Adult male labour constituted about 69% of the total labour- use on the plantations and the majority of the labour was involved in the application of agrochemicals and harvesting of cocoa pods. The quantity of harvested cocoa beans, size of cleared understoreys and quantity of applied agrochemicals significantly affected (at 5% level) the labour-use efficiency in cocoa plantations. Poor remunerations often discourage prospective farm labour from participating in cocoa production. Better farm labour supply level could be achieved if the remuneration for farm labour is handsomely increased.展开更多

In this review, three main strategies, i.e., phytoexclusion, phytostabilization, and phytoextraction, are proposed to establish cropping systems for production of edible and non-edible plants, and for extraction of elements for industrial use. For safe production of food crops, the selection of low-accumulating plants/cultivars and the application of soil amendments are of vital importance. Phytostabilization using non-food energy and fiber plants can provide additional renewable energy sources and economic benefit with minimum cost of agricultural measures. Phytoextracting trace elements (e.g., As, Cd, Ni, and Zn) using hyperaccumulator species is more suitable for slightly and moderately polluted sites, and phytomining of Ni from serpentine soils has shown a great potential to extract Ni-containing bio-ores of economic interests. We conclude that appropriate combinations of soil types, plant species/cultivars, and agronomic practices can restrict trace metal transfer to the food chain and/or extract energy and metals of industrial use and allow safe agricultural activities.展开更多

文摘Considering that even contaminated soils are a potential resource for agricultural production, it is essential to develop a set of cropping systems to allow a safe and sustainable agriculture on contaminated lands while avoiding any transfer of toxic trace elements to the food chain.
