Characterization of soil suitability in the province of Catamarca using geographic information systems

Land suitability analysis using geographic information systems (GIS) is one of the most widely used method today. In this type of studies, GIS and geo-spatial statistical tools are used to evaluate land units and present the results in suitability maps. The present work aims to characterize the suitability of soils in the province of Catamarca for pecan nut production according to the variables: rockiness, salinity, risk of water-logging, depth, texture and drainage described in the Soil Map of Argentina at a scale of 1:500,000 published by the National Institute of Agricultural Technology. A classification of the suitability of the soil cartographic units was made according to crop requirements, applying the methodology proposed by FAO. The standardization of variables made by omega score and the calculation of the spatial classification score were carried out as a result of the synthesis of the spatial distribution of soil suitability. The applied methodology allowed obtaining the soil suitability map resulting in a total of 60,662 km² suitable for pecan nut production, which accounts for 59.8% of the total area of the province.

Sustainability assessment with the green retrofitting concept for building: A study case in the Gresik regency, Indonesia

In green construction, sustainable resources are essential. One such material is copper, which is widely utilized in electronics, transportation, manufacturing, and residential buildings. As a very useful material, it has many beneficial impacts on human life. Observed from the recent demand spike is in line with the overall trend and the current growing smelter construction in Indonesia. Researchers intend to adapt the existing Copper Smelting Plant Building into an environmentally friendly building as a part of the production chain, in addition to reducing public and environmental concerns about the consequences of this development. We have identified a disparity in cost, where the high cost of green buildings is an obstacle to its implementation to enhance the cost performance with increased renewable energy of the Smelter Construction Building, this study investigates the application of LEED parameters to evaluate green retrofit approaches through system dynamics. The most relevant features of the participant assessments were identified using the SEM-PLS approach, which is used to build and test statistical models of causal models. We have results for this Green Retrofitting study following significant variables according to the following guidelines: innovation, low-emission materials, renewable energy, daylighting, reducing indoor water usage, rainwater management, and access to quality transit.

Evaluating how and why the Government of Rwanda failed to achieve middle-income status (MICS) in 2020: Lessons for other African countries

In the 1960s, many East Asian Tiger countries, such as Taiwan, Malaysia, China, etc., faced unfavourable socio-economic conditions like those facing many African countries such as Rwanda. For example, in the 1960s, Singapore was classified as an undeveloped country, with its GDP per capita standing at less than $320. However, all these countries managed to reach a development level like that of Western and North American countries (such as the U.S. and Canada), within a space of less than 15 years. Today, Singapore’s GDP per capita has risen to an incredible $84,501, making it the sixth highest GDP per capita in the world. With Vision 2020, President Kagame promised that Rwanda, which he referred to as “the African lion”, would cruise faster to the middle-income country status faster than Singapore and other middle income status countries, most of which are in East-Asia in less than 20 years. Thirteen years after the introduction of Rwanda’s Vision 2020, President Kagame dashed off the Wall Street Journal and other western media which often referred to Rwanda’s economic development as “the economic tiger of Africa” in his 2013 famous statement as follows: “There is a view that development is a marathon, not a sprint. We do not agree. Development is a marathon that must be run at a sprint. In our pursuit of progress, we have, of course, looked to East Asia’s so-called “tiger” economies for inspiration. But Africa’s experience is unique, and we must now define our own destiny. So, while being described as an “African tiger” is a welcome recognition of how far Rwanda has come, perhaps it isn’t quite right. After all, our continent has its own big cat. Step forward, the new lions of Africa.”. To achieve this objective between 2000 and 2020, Rwanda’s GDP per capita needed to increase from 254.94 USD (2000) to $1240 (in 2020), and the GDP growth rate was to grow consistently between 7% and 10% for a period of 20 years (2000–2020). The objective of this article is to critically analyse how the Government of Rwanda failed to achieve its promise of achieving a middle-income status (MICS) between 2000 and 2020. In 2000 the Rwandan president Paul Kagame launched Rwanda’s Vision 2020. This was a long-term framework for Rwanda’s development in 20 (i.e., 2000–2020). The idea behind Rwanda’s leadership was to imitate whatever Singapore did to become a developed country in just 15 years after its independence in 1965. Blatantly stated, President Paul Kagame wanted to turn his country into the Singapore of Africa. The IMF states that “Vision 2020 was the longer-term socio-economic development framework that sought to transform Rwanda into a middle-income country by 2020”. There is no doubt that Rwanda has made some developmental strides through the implementation of Vision 2020 as an instrument for operationalisation for the Singaporean-modelled developmental state over the past 20 years and has succeeded in some areas. However, the Government of Rwanda has failed in many areas and has failed to achieve the prestigious MICS in 2020. Therefore, among the many gaps in the current literature that this research seeks close is to find out what were some of the accomplishments that Rwanda’s Vision 2020 was unable to achieve? Why did the Government of Rwanda fail to achieve middle-income status within 20 years? What insights can other developing countries gain from Rwanda’s Vision 2020 experience? This study is a significant contribution to the current theoretical knowledge as it sheds light on the reasons behind the Government of Rwanda’s failure to achieve middle-income country status in 2020, a topic that has been largely ignored by the Government’s documents and the media. Despite Rwanda’s Vision 2020, there has been no scientific study to date that has attempted to deal with this topic. Therefore, this study, titled “Why the Government of Rwanda failed to achieve middle-income status (MICS) in 2020” is likely the first of its kind. By addressing

Measuring the consumer’s choice for edible cutlery: A sustainable lifestyle perspective

Edible cutlery is a safe alternative that, if adopted, can act as a panacea to plastic pollution. Consumers who believe in a lifestyle of health and sustainability (LOHAS) can motivate others by taking the lead in this direction. This study has explored the psychological variables associated with LOHAS consumers in conjunction with the product attributes of edible cutlery to check whether these variables can influence lifestyle of health and sustainability (LOHAS) consumers to adopt edible cutlery. An empirical study on 210 LOHAS consumers using Partial Least Squares Structure Equation Modelling (PLS-SEM) and Importance Performance Matrix Analyses (IPMA) showed that social consciousness and subjective norms motivate them to adopt edible cutlery in restaurants. This finding has an implication for hospitality businesses using edible cutlery that can target LOHAS consumers with strategies that affect their social consciousness and subjective norm belief for better adoption intentions.

Response of cucumber cultivars to organomineral fertilizer rate in rainforest savannah

Organomineral fertilizer is used to improve and ameliorate the supply of nutrients in soils. Right and adequate application of fertilizers are determinants of its nutrient supply efficiency, which in turn enhances the vegetative growth and yield of cucumber. Field experiments were conducted at the Research Farm of the Federal University of Agriculture, Abeokuta, Nigeria, to assess the effects of variety and rate of organomineral fertilizer on cucumber growth and yield. Trials were conducted from June to August 2019 and repeated from September to November 2019. The cultivars were Poinsett, Greengo, and Monalisa. The rates of organomineral fertilizer were 0, 2.5, or 5.0 tons. ha⁻¹. The treatments were replicated three times. Cucumber vegetative characters, yield, and yield components were studied. ‘Greengo’ produced the most leaves, followed by ‘Monalisa’; ‘Poinsett’ produced the least. Application of 5.0 tons. ha⁻¹ organomineral fertilizer produced the longest vines and fruits. ‘Greengo’ had the earliest days to 50% flowering, followed by ‘Monalisa’; ‘Poinsett’ had the most days to 50% flowering. Plants treated with an application of 5.0 tons. ha⁻¹ organomineral fertilizer attained 50% flowering in 29 days, but in 30 days with an application of 2.5 tons. ha⁻¹ organomineral fertilizer; the control treatment attained 50% flowering in 33 days. Application of 5.0 tons. ha⁻¹ organomineral fertilizer produced the longest fruits, thicker fruit diameter, and highest fruit yield compared with 2.5 and 0 tons. ha⁻¹ of organomineral fertilizer treatments. The Greengo variety with application of 5.0 tons. ha⁻¹ of organomineral fertilizer is recommended for optimum growth and yield in south western Nigeria.
