Botai 2 1 Department of Information Technology, Central University of Technology, Free State, Private Bag X200539, Bloemfontein 9300, South Africa; [email protected] (M.M.); [email protected] (J.O.B.) 2 South African Weather Service, Private Bag X097, Pretoria 0001, South Africa; [email protected] * Correspondence: [email protected]; Tel.: +27-848491170 Received: 15 July 2020; Accepted: 7 August 2020; Published: 12 August 2020 Abstract: The African continent has a long history of rainfall fluctuations of varying duration and intensities. This has led to varying degrees of drought conditions, triggering research interest across the continent. The research presented here is a bibliometric analysis of scientific articles on drought monitoring and prediction published in Africa. Scientific data analysis was carried out based on bibliometric mapping techniques applied to 332 scientific publications (1980 to 2020) retrieved from the Web of Science (WoS) and Scopus databases. In addition, time series of Standardized Precipitation Evapotranspiration Index for the previous 6 months (SPEI-6) over six regions in the continent was analysed giving the relative comparison of drought occurrences to the annual distribution of the scientific publications. The results revealed that agricultural and hydrological drought studies contributed about 75% of the total publications, while the remaining 25% was shared among socioeconomic and meteorological studies. Countries in the southern, western, and eastern regions of Africa led in terms of scientific publications during the period under review. -

Seed Stocking Via Multi-Task Learning
SEED STOCKING VIA MULTI-TASK LEARNING Yunhe Feng Wenjun Zhou Electrical Engineering & Computer Science Business Analytics & Statistics University of Tennessee University of Tennessee Knoxville, TN 37996 Knoxville, TN 37996 [email protected] [email protected] ABSTRACT Sellers of crop seeds need to plan for the variety and quantity of seeds to stock at least a year in advance. There are a large number of seed varieties of one crop, and each can perform best under different growing conditions. Given the unpredictability of weather, farmers need to make decisions that balance high yield and low risk. A seed vendor needs to be able to anticipate the needs of farmers and have them ready. In this study, we propose an analytical framework for estimating seed demand with three major steps. First, we will estimate the yield and risk of each variety as if they were planted at each location. Since past experiments performed with different seed varieties are highly unbalanced across varieties, and the combination of growing conditions is sparse, we employ multi-task learning to borrow information from similar varieties. Second, we will determine the best mix of seeds for each location by seeking a tradeoff between yield and risk. Third, we will aggregate such mix and pick the top five varieties to re-balance the yield and risk for each growing location. We find that multi-task learning provides a viable solution for yield prediction, and our overall analytical framework has resulted in a good performance. Keywords modern portfolio theory · mean-regularized multi-task learning · graph based multi-task learning · crop yield prediction · seed selection 1 Introduction With the rapid growth of the global population, food demand increases proportionately. -

ABDULKADIR YUSUF ALI iii FOREWORD This thesis is concerned with the current sociopolitical problems of Somalia. The study tries to the best of its ability to present the origins, breadth and width of the security challenges that Somalia faces. Above all, it presents its arguments from an indigenous point of view which is quasi-independent of some of the literature presented by other Western scholars who maybe defiant of some very fine information and who might be missing a few fine points in their analogies. Furthermore, this study elucidates on the fundamental needs to address the root causes of the Somalia problem beginning from its indigenous identity before the arrival of the colonialists. Then it examines the different administrations in power and the political cultures they established by which it believes that regime type and governance might be accountable for the current collapsed nature of the country. -

To minimize the effects of drought on water and food security over Africa, a high-resolution 16 drought dataset is essential to establish robust drought hazard probabilities and to assess drought 17 vulnerability considering a multi- and cross-sectorial perspective that includes crops, hydrological systems, 18 rangeland, and environmental systems. Such assessments are essential for policy makers, their advisors, and 19 other stakeholders to respond to the pressing humanitarian issues caused by these environmental hazards. In 20 this study, a high spatial resolution Standardized Precipitation-Evapotranspiration Index (SPEI) drought 21 dataset is presented to support these assessments. -

Read Full License Loading [MathJax]/jax/output/CommonHTML/fonts/TeX/fontdata.js Page 1/24 Abstract Drought imposes severe, long-term effects on global environments and ecosystems. A better understanding of how long it takes a region to recover to pre-drought conditions after drought is essential for addressing future ecology risks. In this study, drought-related variables were obtained using remote sensing and reanalysis products for 2003 to 2016. The meteorological drought index (standardized precipitation evapotranspiration index [SPEI]) and agricultural drought index (vegetation condition index [VCI]) were employed to estimate drought duration time (DDT) and drought recovery time (DRT). To the basin’s west, decreasing rainfall and increasing potential evapotranspiration led to decreasing SPEI. On the east side, decreasing soil moisture from each depth effects vegetation condition, which results in a decreasing gross primary productivity and VCI. Extreme meteorological drought events are likely to occur in the basin’s northeastern and middle western areas, while the southern basin is more likely to suffer from extreme agricultural drought events. -
Ecosystem Productivity and Water Stress in Tropical East Africa: a Case Study of the 2010–2011 Drought

Robinson 1, Xi Yang 2 and Jung-Eun Lee 1,* 1 Department of Earth, Environmental, and Planetary Sciences, Brown University, Providence, RI 02912, USA; [email protected] 2 Department of Environmental Sciences, University of Virginia, Charlottesville, VA 22904, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-401-863-6465 Received: 25 January 2019; Accepted: 12 March 2019; Published: 22 March 2019 Abstract: Characterizing the spatiotemporal patterns of ecosystem responses to drought is important in understanding the impact of water stress on tropical ecosystems and projecting future land cover transitions in the East African tropics. Through the analysis of satellite measurements of solar-induced chlorophyll fluorescence (SIF) and the normalized difference vegetation index (NDVI), soil moisture, rainfall, and reanalysis data, here we characterize the 2010–2011 drought in tropical East Africa. The 2010–2011 drought included the consecutive failure of rainy seasons in October–November–December 2010 and March–April–May 2011 and extended further east and south compared with previous regional droughts. During 2010–2011, SIF, a proxy of ecosystem productivity, showed a concomitant decline (~32% lower gross primary productivity, or GPP, based on an empirical SIF–GPP relationship, as compared to the long-term average) with water stress, expressed by lower precipitation and soil moisture. Both SIF and NDVI showed a negative response to drought, and SIF captured the response to soil moisture with a lag of 16 days, even if it had lower spatial resolution and much smaller energy compared with NDVI, suggesting that SIF can also serve as an early indicator of drought in the future. -

Iraq's Water Woes
Iraq’s Water Woes: Present and Future Challenges to Scarcity and Abundance October 2020 Marcus Arcanjo Introduction Sustainable peace in Iraq has long been a challenge. Despite recent successes in local communities––such as the military wins against ISIS––a number of socio-economic, political, and environmental challenges remain. Climate change, environmental degradation, and resource scarcity have been agreed upon by experts to be multipliers of existing threats rather than direct causes of conflict and disruptions to peace. This paper explores the role of water and the vulnerability to environmental issues, including climate change, in Iraq. It studies the history of water insecurity in Iraq and how it can exacerbate existing fragilities and hostilities. The inability to access basic resources combined with a troublesome political environment fuels the potential for conflict as livelihoods are lost and a lack of adaptive capacity causes heightened community tensions. Equally, this paper seeks to explain the paradoxical situation in this country in terms of a lack of water for consumption, hygiene, and agriculture but an abundance of flooding in the Southern regions resulting from climate change–related sea level rise. Lastly, potential pathways forward are discussed. History of Water Challenges Water flow from the Euphrates and Tigris, rivers that supply up to 98 per cent of Iraq’s water, has decreased by 30 percent in the last four decades.1 A 2018 report by the Iraq Energy Institute acknowledges the reductions in water flow coming from dam construction in neighboring countries, increased water use by the oil industry, and the destruction of infrastructure resulting from war.2 Turkey and Syria, upstream neighbours, developed large infrastructure projects such as canals and dams that hinder the flow of water downstream. -
