Zero Hunger

Timely and reliable information about crop management, production, and yield is considered of great utility by stakeholders (e.g., national and international authorities, farmers, commercial units, etc.) to ensure food safety and security. By 2050, according to Food and Agriculture Organization (FAO) estimates, around 70% more production of agricultural products will be needed to fulfil the demands of the world population. Likewise, to meet the Sustainable Development Goals (SDGs), especially the second goal of “zero hunger”, potential technologies like remote sensing (RS) need to be efficiently integrated into agriculture. The application of RS is indispensable today for a highly productive and sustainable agriculture. Therefore, the present study draws a general overview of RS technology with a special focus on the principal platforms of this technology, i.e., satellites and remotely piloted aircrafts (RPAs), and the sensors used, in relation to the 5th industrial revolution. Nevertheless, since 1957, RS technology has found applications, through the use of satellite imagery, in agriculture, which was later enriched by the incorporation of remotely piloted aircrafts (RPAs), which is further pushing the boundaries of proficiency through the upgrading of sensors capable of higher spectral, spatial, and temporal resolutions. More prominently, wireless sensor technologies (WST) have streamlined real time information acquisition and programming for respective measures. Improved algorithms and sensors can, not only add significant value to crop data acquisition, but can also devise simulations on yield, harvesting and irrigation periods, metrological data, etc., by making use of cloud computing. The RS technology generates huge sets of data that necessitate the incorporation of artificial intelligence (AI) and big data to extract useful products, thereby augmenting the adeptness and efficiency of agriculture to ensure its sustainability. These technologies have made the orientation of current research towards the estimation of plant physiological traits rather than the structural parameters possible. Futuristic approaches for benefiting from these cutting-edge technologies are discussed in this study. This study can be helpful for researchers, academics, and young students aspiring to play a role in the achievement of sustainable agriculture.

Urban agriculture is often advanced as a sustainable solution to feed a growing urban population, offering a number of benefits: improved fresh food access, CO2 absorption, social justice and social cohesion among others. Going beyond these direct tangible/objective benefits from urban agriculture, in this paper we ask: How can growing food in the cities teach us about taking care of each other and the natural environment? We use the example of urban food autonomy movements to discuss the transformative potential of a grassroots-led initiative promoting permaculture, which is anchored in three “ethics”: care for the earth, care for the people, and fair share. Through examining the philosophical underpinnings of “autonomy” and “care”, we explore how urban food autonomy initiatives can enable the development of an ethics of care, especially using permaculture inspirations. Our theoretical review and case analysis reveal that “autonomy” can never be achieved without “care” and that these are co-dependent outcomes. The urban food autonomy initiatives are directly relevant for the achievement of the three of the UN’s 17 Sustainable Development Goals: “Zero Hunger,” “Life on Land” and “Climate Action”, and contribute to a culture of care. Indeed, urban agriculture can act as a powerful education platform for the engagement of diverse stakeholders while also supporting a collective transformation of values.

Incandescent Lamps

High-tech greenhouses and artificial light applications aim to improve food production, in line with one of the sustainable development goals of the UN Agenda 2030, namely, “zero hunger”. In the past, the incandescent lamps have been used for supplementary lighting (SL) at higher latitudes to increase greenhouse production during the dark season. Light-emitting diodes (LED) have been replacing gas discharge and incandescent lamps, and their development is expanding SL applications in different agricultural scenarios (e.g., urban farming, middle latitudes). In fact, recent research on LED applications in Mediterranean greenhouses have produced encouraging results. Since middle latitudes have a higher daily light integral (DLI) than higher latitudes in the dark season and climate conditions influence the installed power load of greenhouses, LED installation and management in Mediterranean greenhouses should be different and less expensive in terms of investment and energy consumption. Accordingly, the aim of this review is to outline the state of the art in LED applications and development, with a focus on latitude-related requirements. Tomato was used as a representative crop.

The Impact

Given the impact of COVID-19 and the desert locust plague, the Ethiopian food security issue has once again received widespread attention. Its food crisis requires comprehensive and systematic research to achieve the United Nations Sustainable Development Goal of zero hunger. This review discusses the current situation and the causes of food security in Ethiopia. We focus on the challenges in the food security assessment field. The article lists seven typical causes of food insecurity and three roots of food security in Ethiopia. Long-term food security assessment and a comprehensive understanding and manageability for food security causes are considered as the main existing research challenges. Climate-resilient management, water management, and long-term ecosystem network monitoring and data mining are suggested as potential roadmap for future research.

Zero Hunger

The United Nations Agenda 2030 contains 17 sustainable development goals (SDGs). These goals are formulated in anthropocentric terms, meaning that they are to be achieved for the sake of humans. As such, the SDGs are neglecting the interests and welfare of non-human animals. Our aim in this paper was to ethically evaluate the assumptions that underlie the current anthropocentric stance of the SDGs. We argue that there are no good reasons to uphold these assumptions, and that the SDGs should therefore be reconsidered so that they take non-human animals into direct consideration. This has some interesting implications for how we should understand and fulfil the pursuit of sustainability in general. Most noticeably, several SDGs—such as those regarding zero hunger (SDG 2), good health and wellbeing (SDG 3), clean water and sanitation (SDG 6)—should be achieved for animals as well. Moreover, the measures we undertake in order to achieve the SDGs for humans must also take into direct account their effects on non-human animals.

The transformation in education must be directed in accordance with Sustainable Development Goals (SDGs) program. This article aimed to discuss the potential support of New Biology in achieving the formulated SDGs. This literature review covered 31 articles which were published since 2010 to 2019. The keywords used to collect the data were new biology, future biology, biology education, biological science, and biology. The review results informed that New Biology can potentially enact five goals of SDGs, i.e. goal 2 (Zero Hunger), goal 3 (Good Health and Well-being), goal 4 (Quality Education), goal 6 (Clean Water and Sanitation), and goal 7 (Affordable and Clean Energy). By considering the findings, it is suggested to promote New Biology approach in Indonesian educational system.

Water Retention Properties

Crop farming in Botswana is very modest and of high risk compared to its neighboring countries because of significant dependency on reduced and unreliable rainfall and as a result of soils with poor water holding capacity and low cation exchange capacity. For this reason, only about two thirds of the available arable land are planted and of the planted land only about half is harvested, which translates into only one third of productive arable land. This study examines how addition of poultry litter (PL) biochar affects water retention properties of Botswana’s sandy soils. While many variables should be studied to fully comprehend this aspect, this paper exploits in detail, effects of biochar addition in reducing rate of water loss by evaporation. This work provides convincing evidence that addition of PL-derived biochar (as little as 10%) can significantly reduce water loss by evaporation, thus increasing water soil retention. It is demonstrated that water retention properties increase with increasing rate of biochar application. Two types PL-derived biochar were studied: (i) one with sunflower husks bedding and another (ii) with woodchips bedding. Though both biochars showed similar response to the test, the biochar with sunflower husks was slightly superior. Biochar also indicated significant hygroscopicity, when dried and left exposed to the atmosphere, as moisture content increased with increasing humidity. Based on initial indicators, further study should be done at laboratory and field scale to determine optimum conditions of biochar application in the quest to improve food security for Botswana, as well as improve employment and environmental goals of the country. A comprehensive further study should critically examine Field Capacity, Permanent Wilting Point, and Plant Available Water. As an ultimate goal, enhancing soil moisture retention properties of Botswana’s sandy soil enables to increase success rate in the traditional farming sector and, consequently, offers potential to accomplish “No Poverty” and “Zero Hunger” sustainable development goals.
