Remote Sensing Applications for Water Resources Management and Monitoring in Southern Africa: A Review Kgosiesele, Ednah; Molefe, John Isaac; Moalafhi, Ditiro B.; Mzuku, Monga Water is a scarce resource that needs careful planning to ensure its sustainability for current and future needs. Globally, freshwater resources are facing increased rates of decline and degradation due to climate vulnerability, and other direct anthropogenic pressures such as poor conservation and unsustainable management practices. The world population has been increasing over the past decades, with more than half of the global increase projected for Sub-Saharan Africa by 2050. With increasing population, water demand, over-extraction, scarcity, and conflict are inevitable. The effects are more evident in semi-arid regions due to low and variable rainfall patterns and high evaporation rates, leading to over-reliance on groundwater resources. Quantifying the spatial and temporal variations of water resources and their key drivers is important for guiding effective decision-making and water management strategies. Traditional water resources monitoring relies on in situ measurements which has proven to be a challenge in Sub-Saharan Africa due to the sparse monitoring network. Remote Sensing if combined with ground observations can serve as a useful complementary tool due to its wide spatial coverage and high temporal resolution. Its utilisation on aquatic ecosystems has increased over time, with varying degrees of applications across geographical regions. In this paper, we review the application of remote sensing and earth observation for monitoring water resources towards water secure Southern Africa. We highlight current research progress, gaps, and challenges for monitoring water quality and quantity using satellite data. From literature based on practices and research, there is considerable uptake of remote sensing as a complimentary tool for water resources management and monitoring which is necessitated by the need for solid and reliable databases that are critical for evidence-based decision-making. Major challenges of satellite sensor limitations and limited validation of remotely sensed products are highlighted together with motivations towards big data and cloud computing capabilities that can be leveraged. Finally, we discuss future research areas, and how new satellite sensors, can be combined with modelling tools to effectively guide policy and planning for water resources of Southern Africa under a changing climate.

Agroforestry for Degraded Landscapes: Recent Advances and Emerging Challenges - Vol. 2. Dagar, Jagdish Chander; Gupta, Sharda Rani; Teketay, Demel This book presents various aspects of agroforestry research and development, as well as the latest trends in degraded landscape management. Over the last four decades, agroforestry research (particularly on degraded landscapes) has evolved into an essential problem-solving science, e.g. in terms of sustaining agricultural productivity, improving soil health and biodiversity, enhancing ecosystem services, supporting carbon sequestration and mitigating climate change. This book examines temperate and tropical agroforestry systems around the world, focusing on traditional and modern practices and technologies used to rehabilitate degraded lands. It covers the latest research advances, trends and challenges in the utilization and reclamation of degraded lands, e.g. urban and peri-urban agroforestry, reclamation of degraded landscapes, tree-based multi-enterprise agriculture, domestication of high-value halophytes, afforestation of coastal areas, preserving mangroves and much more. Given its scope, the book offers a valuable asset for a broad range of stakeholders including farmers, scientists, researchers, educators, students, development/extension agents, environmentalists, policy/decision makers, and government and non-government organizations.

Promoting Bamboo-Based Agroforestry for Enhancing Ecosystem Services from Degraded Lands. Solomon, T.; Moon, H.; Abebe, S.; Minale, A.S.; Teketay, Demel Agroforestry innovations on degraded lands have been prioritized for promoting environmental sustainability, advancing food and fodder security, and achieving United Nations Sustainable Development Goals. Although neglected in scientific research and development, bamboo-based agroforestry has traditionally been managed on family farms because of their great socioeconomic values in rural lives especially in Asia. Recently, there has been increasing interest in their role in soil health improvement, biomass production, and climate change mitigation. However, our knowledge on the contribution of bamboo-based agroforestry for enhancing provisioning ecosystem services is very limited. The aim of this chapter is to compile existing information on social, economic, and ecological implications of bamboo-based agroforestry with an aim to create and advance our understanding on the role of bamboo in enhancing ecosystem services.

In Pursuit of Sustainable Tourism in Botswana: Perceptions of Maun Tourism Accommodation Operators on Tourism Certification and Eco-Labelling. Motsaathebe, Godiraone Trompies; Hambira, Wame L. Tourism is one of the main engines of growth for many economies around the world. This growth has also brought up some negative environmental and socio-economic impacts. Tourism stakeholders have been forced to come up with several mitigation strategies such as certification and eco-labelling to combat these challenges. As a rarely explored concept in the Botswana tourism industry, this paper seeks to determine tourism accommodation operators’ perceptions about tourism certification and eco-labelling based on the Botswana Ecotourism Certification System. A qualitative data enquiry was used in which corporate executives of tourism accommodation facilities were interviewed to determine their perceptions on tourism certification and eco-labelling. The results revealed that tourism businesses in Maun have positive perceptions about tourism eco-labelling and are willing to participate in the program. However, lack of awareness about the scheme and other main factors hinders their attempts to participate in the program. The study recommends that policymakers and developers should intensify awareness-raising within the tourism business community and to devise strategies to incentivize companies to take the necessary action towards building sustainable tourism in Maun.
