Chapter 10 of Pediatric Surgery: This chapter provides an overview of some of the challenges when providing anaesthesia care for children in Africa. The chapter reviews
the cardiac, respiratory, and renal differences of children in comparison to adults. Additionally, it addresses preoperative asses...sment, including guidelines for nothing by mouth (NPO, or nil per os), general and regional anaesthesia, intraoperative monitoring, airway management, and postoperative care

Agricultural ecosystems provide humans with food, forage, bioenergy and pharmaceuticals and are essential to human wellbeing. These systems rely on ecosystem services provided by natural ecosystems, including pollination, b...iological pest control, maintenance of soil structure and fertility, nutrient cycling and hydrological services. Preliminary assessments indicate that the value of these ecosystem services to agriculture is enormous and often underappreciated. Agroecosystems also produce a variety of ecosystem services, such as regulation of soil and water quality, carbon sequestration, support for biodiversity and cultural services. Depending on management practices, agriculture can also be the source of numerous disservices, including loss of wildlife habitat, nutrient runoff, sedimentation of waterways, greenhouse gas emissions, and pesticide poisoning of humans and non-target species. The tradeoffs that may occur between provisioning services and other ecosystem services and disservices should be evaluated in terms of spatial scale, temporal scale and reversibility. As more effective methods for valuing ecosystem services become available, the potential for ‘win–win’ scenarios increases. Under all scenarios, appropriate agricultural management practices are critical to realizing the benefits of ecosystem services and reducing disservices from agricultural activities.

Climate change is a verified, global phenomenon, but its consequences will not be evenly distributed. Developing countries and small island nations will be the most affected. Countries will experience more frequent extreme weather events and resulting changes in water quality and availability, incre...ased contamination of air, and food security problems. Health impact due to climate change include diarrhoeal diseases, vector-borne diseases, heat stress, malnutrition, deaths and injuries due to extreme weather events and mental stress.
