Wildfire is one of the most critical natural disasters that threaten wildlands and forest resources. Traditional firefighting systems, which are based on ground crew inspection, have several limits and can expose firefighters’ lives to danger. Thus, remote sensing technologies have become one of the most demanded strategies to fight against wildfires, especially UAV-based remote sensing technologies. They have been adopted to detect forest fires at their early stages, before becoming uncontrollable.
Ethiopia has experienced rapid urbanization over the past three decades. Several cities expanded rapidly and many satellite towns sprung up around the major cities. The high rate of urbanization and urban growth resulted in high demand for urban land, mainly for industrial, commercial, and residential purposes. In order to meet the demand, an enormous amount of land has been made available for urban use, mainly through land conversion. However, we know very little about how efficiently cities use urban land.
Tracking progress toward the Sustainable Development Goals (SDGs) requires monitoring of various social-ecological indicators over space and time, including the ratio of land consumption rate to population growth rate (LCRPGR), an indicator of land-use efficiency (SDG 11.3.1). In this study, we analyzed state-of-the-art Earth observation data (1975–2015) to address three key questions. First, how has the LCRPGR varied over space and time? Second, how is built-up expansion related to population increase across regions?
The energy, exergy and economic analysis of indirect type solar dryer (ITSD) was performed while drying green chilli under forced and natural convection. Fans powered by PV panels were used for forced convection setup. The collector and drying efficiencies of the forced convection dryer were found to be 63.3% and 10.4% and the same was 53.84% and 8.90% in natural convection ITSD, respectively. The specific moisture extraction rate (SMER) of green chilli in ITSD was found to be 0.6526 and 0.5603 kg/kW-h under forced and natural convection, respectively.
In this brief perspective piece, a rural sexual assault nurse examiner (SANE) program is described in the hopes that dissemination will lead to increased numbers of rural SANEs, increased reporting of sexual assaults in rural and underserved communities, increased prosecution rates of sexual assault perpetrators, and program sustainability through the provision of a nurse-centered approach to training and support. This article contributes SDGs 3, 5, 9, and 16.
This article highlights the winning proposals of the fifth edition of the Elsevier Foundation Green & Sustainable Chemistry Challenge. The winning proposals were chosen for their innovative green chemistry aspects and their large positive impact on the environment, contributing to SDGs 7, 8, 10, 12, 13, 14 and 15.
The Common Agricultural Policy (CAP) is the guiding policy for agriculture and the largest single budget item in the European Union (EU). Agriculture is essential to meet the Sustainable Development Goals (SDGs), but the CAP's contribution to do so is uncertain. We analyzed the distribution of €59.4 billion of 2015 CAP payments and show that current CAP spending exacerbates income inequality within agriculture, while little funding supports climate-friendly and biodiverse farming regions.
Global climate change and land degradation are two grand changes facing humanity. In this perspective, we examine how degraded and abandoned farmland can be harnessed to fight climate change. Building upon and extending natural climate solutions, we suggest that the carbon capture and storage of abandoned farmland can be accelerated and maximized through restoring the diversity of plant species, applying biochar to soil, and co-developing renewable energy such as solar power. The benefits of these approaches extend far beyond climate-change mitigation and land restoration.
This study investigated the drying behaviour of purple-speckled Cocoyam and the effect of drying temperature (40 °C, 60 °C and 75 °C), slice thickness (4 mm, 7 mm and 10 mm) and pre-treatments (blanching in boiling water for 3 min, blanching in boiling water for 3 min followed by dipping in 0.1 per cent sodium metabisulfite for 5 min) and non-pre-treated slices. The process and quality criteria under consideration included the total drying time, rehydration ratio, colour difference, browning index and specific energy consumption.
In this paper, we revisit the entrepreneurship and poverty relationship under a eudaimonic perspective that brings together conversion factors, and future prosperity expectations. Based on an fsQCA of changes in life circumstances of 166 farm households in rural Kenya, we explore how different combinations of conversion factors enable distinct forms of entrepreneuring in the pursuit of prosperity.
