Climate change-induced heat stress combines two challenges: high day- and nighttime temperatures, and physiological water deficit due to demand-side drought caused by increase in vapor-pressure deficit. It is one of the major factors in low productivity of maize in rainfed stress-prone environments in South Asia, affecting a large population of smallholder farmers who depend on maize for their sustenance and livelihoods.

Brown spot, caused by Bipolaris oryzae, is becoming more prevalent and important in the Philippines but risk assessment is limited. Surveys of 2186 farmers' fields were conducted in the major rice‐growing areas in the country from 2015 to 2018 to analyse the components of production situation (PS) that contribute to the area under the progress curve of brown spot incidence (aBS). Based on lasso regression, the components of PS that influence aBS, in decreasing order, are ecosystem (irrigated vs. rainfed), crop establishment method (direct seeding vs.

The Enviro-Champs initiative was developed as a community driven, citizen science initiative in Mpophomeni township in Kwa-Zulu Natal (KZN), South Africa. Over time, the scope of work done and data collected by the Enviro-Champs has expanded. There is now recognition both locally and globally that the Enviro-Champs initiative shows great promise for national and global upscaling. However, several areas within the initiative remain where it could be improved, especially technologically.

Finding out how to scale innovations successfully is high on the agendas of researchers, practitioners and policy makers involved in agricultural development. New approaches and methodologies seek to better address related complexities, but none of them include a systematic perspective on the role of capacity in (partnerships for) scaling innovations. We posit that this has left an important topic insufficiently addressed in relation to partnerships for scaling innovations.

Despite decades of research and dissemination of improved sweetpotato varieties, uptake at scale remains low and envisaged development goals of food security and livelihoods remain elusive. This is despite demonstrated impacts of such technologies in combating food and nutrition insecurity, amidst global challenges like climate change.

The role of market concentration and potential market power exertion in the agri-food industry is a topic of longstanding interest and concern to policymakers, stakeholders, and researchers. This study provides a comprehensive overview of recent trends in market concentration upstream, midstream, and downstream the agri-food industry at the global, regional, and country level, and assesses how and to what extent concentration could be affecting market conduct and performance of food systems in developed and developing countries.

The Guide includes detailed protocols and procedures for evaluating cacao in various forms, such as unroasted cacao bean coarse powder, cacao mass, and chocolate. These methodologies have been developed over several years by a diverse group of experts, enabling objective assessments of cacao quality and flavour. It provides a universal language for describing cacao attributes, for a shared understanding among cacao professionals worldwide.

Rangelands in arid and semi-arid regions serve as grazing land for domesticated animals and therefore offer livelihood opportunities for most pastoral communities. Thus, the exposure of most rangelands in arid and semi-arid regions to threats that are associated with natural, social, economic, and political processes affects their capacity to provide socioeconomic and environmental support to the immediate and global communities.

Indonesia represents an interesting case for analysis of the relationship between multi-level governance and climate governance for three main reasons. It is a highly decentralized country; it is a major contributor to land-based greenhouse gas emissions; and it is extremely vulnerable to climate change. The chapter first provides a broad overview on Indonesia’s climate governance in the context of decentralization, and then focuses on sub-national governance of climate change mitigation in the land use sector, the largest contributor to greenhouse gas emissions in the country.

While water-energy-food (WEF) Nexus is one of the most important, and widely investigated, environmental topics of our time, previous stock taking efforts possess notable limitations, namely (i) their focus is restricted to research articles, and (ii) there is less focus on nexus permutations that begin with energy and food. This paper assembled more than 900 documents and systematically categorized them according to more than 10 key parameters (e.g. scale, methods, limitations), to characterize approaches, achieved outcomes and presence of variables likely to support on-the-ground change.

Mapping stakeholders and their potential roles for prevention and reduction of food waste (FW) supports a coherent, coordinated and complementary approach to quantification, causes identification and scaling up of feasible solutions for significant returns on investment. State and nonstate stakeholders were mapped in selected municipalities: Colombo metropolitan area (Colombo, Sri Jayewardenepura-Kotte, Negombo, Kaduwela and Moratuwa municipal council areas), Jaffna, Kandy, Batticoloa, Kurunegala and Galle.

In combination with political, cultural, and economic factors, issues related to environmental resources and the management of land have played a crucial role in driving conflict in Mindanao. Climatic stressors and shocks are altering food, land, and water systems, and driving important socioeconomic challenges for food security and the stability of rural livelihoods across the Philippines.
