Urban farms provide a large diversity of ecosystem services, which collectively have a positive effect on different constituents of human wellbeing. However, urban farms are facing increasing pressure due to accelerated urbanization and socioeconomic transformation, especially in rapidly developing countries such as Myanmar. There is an increasing call to harness the multiple benefits that urban farms offer in order to foster urban green economic transitions and increase the wellbeing of urban residents. This study examines how different types of urban farms provide ecosystem services, focusing on Pyin Oo Lwin, one of the secondary cities of Myanmar. We conduct household surveys with urban farmers representing the three main types of urban farms encountered in the city, namely seasonal crop farms (N = 101), coffee farms (N = 20), and nurseries (N = 20). The results suggest that all types of urban farms in our sample provide multiple provisioning, cultural, regulating, and supporting ecosystem services, which collectively contribute directly to different constituents of human wellbeing such as (a) food security, (b) livelihoods and economic growth, and (c) public health and social cohesion. Food crops and commercial crops (e.g., coffee) are the major provisioning ecosystem services provided by our studied urban farms, with some farms also producing medicinal plants. These ecosystem services contribute primarily to farmer livelihoods and economic growth, and secondarily to household food security (through self-consumption) and health (through nutritious diets and medicinal products). Food sharing is a common practice between respondents for building social cohesion, and is practiced to some extent by most seasonal crop farmers. Almost all surveyed urban farms in our sample provide diverse cultural services to their owners, ensuring the delivery of intangible benefits that have a further positive effect on human wellbeing. It is argued that efforts should be made to ensure the continuous supply of these ecosystem services in order to contribute to urban green economic transitions in Pyin Oo Lwin and other similar secondary cities.

Agriculture is critically important for African societies and economies but ensuring food security for Africa’s growing population is a major challenge. One particular concern are pesticides called ‘neonicotinoids’, which render all parts of a plant toxic to all insects and contaminate the soil and water bodies. By exposing all organisms to the toxins, neonicotinoids also harm beneficial insects that provide many important ‘ecosystem services’, such as pollination, soil development, and natural pest control, which are an integral part of sustainable agriculture. Neonicotinoids have contributed to the loss of ecosystem services from pollinators and other insects in Europe and elsewhere, and several of them have been banned in the (European Union) EU and other countries due to their harmful effect on beneficial insects. Africa, with its rich biodiversity and heavy reliance on agricultural production, is one of the fastest-growing pesticide markets in the world, so protecting it from the harmful effects of neonicotinoids is vital to ensuring a sustainable agriculture that provides food security. The Academy of Science of South Africa (ASSAf), in collaboration with the German National Academy of Sciences Leopoldina and the Network of African Science Academies (NASAC) has recently completed a project exploring the use and effects of neonicotinoids in African agriculture. This project brought together experts from 17 African countries, reviewed the relevant African scientific literature, and analysed the state of knowledge on neonicotinoids and their impact on ecosystem services for agriculture and on biodiversity in Africa. The resultant report ‘Neonicotinoid insecticides: use and effects in African agriculture. A review and recommendations to policy makers’ (NASAC, 2019) has collated an unprecedented amount of information, identified gaps in scientific knowledge and research relating to neonicotinoids in Africa, and developed key recommendations from science to policy-makers to ensure the sustainability of African agriculture and thus food security. One year after the launch of the NASAC report, the purpose of this virtual event was to introduce the report, including an update on recent global scientific and African policy developments regarding neonicotinoids, and to discuss its implications with a wide range of stakeholders, with the aim of stimulating policy and research action on this important issue. The target audience and participants included South African and Southern African Development Community (SADC) policymakers, regulatory agencies, government departments, agricultural associations, extension-service providers, research institutes, international development agencies, representatives of embassies, and other interested stakeholders.

Food security is a rising concern around the world, especially in developing countries within arid and semi-arid regions. Ecosystem provides different services to support living and human survival, which includes some major food sources around the world like agriculture, fisheries, and livestock. With advancing times, humans improved these services and produced enough food to support the rising population. However, with increasing greenhouse gases, a new problem came into existence, commonly known as climate change (CC), which accelerated issues like food security and safety. Under such issues, people don't have access to basic facilities and food supply to survive, and with future population growth estimates, it is becoming even more difficult. Some major food sources together with alternate sources are discussed in this chapter. Upcoming CC impacts are discussed in detail in relation to major food sources and supported by world maps to provide a better picture. Major actions, government initiatives, and some suggestions are also provided to overcome this global crisis.

Abstract This study examined the role of ecosystem services in enhancing climate change resilience of local communities in Ngarambe-Tapika Wildlife Management Area (WMA). The study aimed to identify forms of ecosystem services that can be gained from conservation of a WMA in relation to climate change adaptation. The design for this study adopted both a quantitative and a qualitative research approach. The study was undertaken in Ngarambe-Tapika WMA located between latitude 39° S and 39°30' S and between longitude 12°30' E and 13° E. It is located alongside the north-eastern border of the Selous Game Reserve. The area is also the home of local people whose lifestyles and livelihoods are intricately tied to the biological diversity and the functioning of this natural system. Purposive sampling was employed in selecting respondents for the household questionnaire, focus group discussions and key informant interviews. This study found that income obtained from Ngarambe-Tapika ecosystems by the communities were invested in material welfare and livelihoods that enhance resilience to climate change, primarily social services (54.9%) such as construction of houses, dispensaries and rehabilitation of the primary schools, and some of the money was spent on electricity provision for the community and energy for light and water pumps. Other benefits included employment (16.5%), protection from dangerous and problematic wildlife (14.3%) and petty business (14.3%). Generally, in Ngarambe-Tapika WMA there is a need to emphasize conservation awareness and extension programmes which advocate sustainable utilization of wildlife resources, and adopt an integrated approach of climate-smart agriculture to address the challenges related to food insecurity and climate change and variability. The latter would enable increased agricultural productivity to support equitable increases in farm incomes, improve food security and build resilience of agricultural and food security systems to adapt to climate change and variability.
