The greenhouse gases (GHG) emissions in the European Union (EU) are mainly caused by human activity from five sectors—power, industry, transport, buildings, and agriculture. To tackle all these challenges, the EU actions and policies have been encouraging initiatives focusing on a holistic approach but these initiatives are not enough coordinated and connected to reach the much needed impact. To strengthen the important role of regions in climate actions, and stimulate wide stakeholders’ engagement including citizens, a conceptual framework for enabling rapid and far-reaching climate actions through multi-sectoral regional adaptation pathways is hereby developed. The target audience for this framework is composed by regional policy makers, developers and fellow scientists. The scale of the framework emphasizes the regional function as an important meeting point and delivery arena for European and national climate strategies and objectives both at urban and rural level. The framework is based on transformative and no-regret measures, prioritizing the Key Community Systems (KCS) that most urgently need to be protected from climate impacts and risks.

Urban agriculture is increasingly recognized as an important sustainable pathway for climate change adaptation and mitigation, for building more resilient cities, and for citizens’ health. Urban agriculture systems appear in many forms – both commercial and non-commercial. The value of the services derived from urban agriculture, e.g., enhanced food security, air quality, water regulation, and high level of biodiversity, is often difficult to quantify to inform policymakers and the general public in their decision making. We perform a contingent valuation survey of four different types of urban agriculture Where the citizens of Oslo are asked about their attitudes and willingness to pay non-commercial (urban community gardens and urban gardens for work training, education and kindergartens) and for commercial (i.e. aquaponics and vertical production) forms of urban agriculture. Results show that the citizens of Oslo are willing to increase their tax payments to contribute to further development of urban farming in Oslo.

The value of the services derived from urban agriculture, e.g. enhanced food security, air quality, water regulation, and high level of biodiversity, is often difficult to quantify to inform policymakers and the general public in their decision making. We perform a contingent valuation survey regarding four different types of urban agriculture in Oslo. The citizens of Oslo are asked about their attitudes and willingness to pay for non-commercial and commercial urban agriculture. The non-commercial agriculture consists of urban community gardens for the citizens and urban gardens for work training, education and kindergartens. On the other hand, the commercial urban agriculture consists of aquaponics and vertical production. Results show that the citizens of Oslo are willing to increase their tax payments to contribute to further development of urban farming in Oslo.

The site-specific nutrient management (SSNM) strategy provides guidelines for effective nitrogen, phosphorus and potassium management to help farmers make better decisions on fertilizer input and output levels in rice (Oryza sativa) production. The SSNM fertilizer recommendations are based on the yield goal approach, which has been frequently cited in empirical studies. This study evaluates the assumptions underlying the SSNM strategy for rice in the top rice-producing countries around the world, including India, Indonesia, the Philippines, Thailand, and Vietnam. Using a generalized quadratic production function, I explore whether major nutrients are substitutes as inputs and if there are complementarities between inorganic fertilizer and soil organic matter (SOM). The results suggest the relationships among major nutrients vary across sites—some inputs are complements, some are substitutes, and some are independent. The SOM also significantly affects the nitrogen fertilizer uptake. I conclude by suggesting that the SSNM strategy can be made to be more adaptive to farmer’s fields if these relationships are accounted for in the fertilizer recommendation algorithm.

This chapter analyses the main challenges and opportunities to promote sustainable biogas technology adoption by smallholders through integrated food and energy systems (IFES), using a case study from Malonga village in the Limpopo Province of South Africa. Biogas has become attractive in recent years because of its multiple benefits and the contributions it can make to the UN SDGs. However, in Africa, its adoption remains low, due to several constraints, including: (1) water scarcity and lack of access to feedstocks; (2) high initial/upfront cost of installation and lack of investment; (3) lack of skilled labour for installation, operation and maintenance; (4) limited training facilities; (5) inadequate policy support and extension services; and (6) slow behavioural and social acceptance. Based on the information collected, integrated framework conditions that can encourage the adoption of smallholder biogas technology through IFES, were suggested. IFES will only succeed in delivering benefits, if the necessary framework conditions, such as adequate feedstock and water, training, policy support, stakeholder collaboration, credit and insurance and support services are provided. The implementation of the necessary framework conditions for biogas technology should be underpinned by conducting an integrated research study on using IFES type 2 in the context of smallholder farmers in Africa.

This chapter emphasizes the need for active stakeholder engagement right through from strategy development to planning and implementation, to realize the benefits of sustainable bioeconomy development. In general, this varies between regions and countries. In the EU, it is considered important to engage stakeholders at all stages, whereas in developing countries engaging stakeholders so far has not been given much importance when launching new strategies. Stakeholders, including the private sector, research institutions, farmers organizations, the government and non-governmental organizations, all have important roles to play. The chapter focuses on the why, how and what type of stakeholders should be engaged, and the relevant benefits and challenges. It discusses experiences from the EU and other regions where stakeholder engagement (both formal and informal) and participative governance have led to or are necessary for successful and sustainable bioeconomy development.

We examine the origins, implications, and consequences of yield-based N fertilizer management. Yield-based algorithms have dominated N fertilizer management of corn (Zea mays) in the United States for almost 50 yr, and similar algorithms have been used all over the world to make fertilizer recommendations for other crops. Beginning in the mid-1990s, empirical research started to show that yield-based rules-of-thumb in general are not a useful guide to fertilizer management. Yet yield-based methods continue to be widely used, and are part of the principal algorithms of nearly all current “decision tool” software being sold to farmers for N management. We present details of the theoretical and empirical origins of yield-based management algorithms, which were introduced by George Stanford (1966, 1973) as a way to make N fertilizer management less reliant on data. We show that Stanford’s derivation of his “1.2 Rule” was based on very little data, questionable data omissions, and negligible and faulty statistical analysis. We argue that, nonetheless, researchers, outreach personnel, and private-sector crop management consultants were obliged to give some kind of N management guidance to farmers. Since data generation is costly, it is understandable that a broad, “ball park” rule-of-thumb was developed, loosely based on agronomic principles. We conclude by suggesting that technology changes now allow for exciting new possibilities in data-intensive fertilizer management research, which may lead to more efficient N management possibilities in the near future.

Mapping and valuating ecosystem services has gained increasing attention over the last years and remains high in the research agenda. In this paper, a mixed methods approach is used to valuate ecosystem services provided by the Divici-Pojejena wetland in Romania. A qualitative part relied on focus group discussions and interviews to identify key stakeholders and the ecosystem services provided by the wetland site. The benefit transfer (BT) method was used for the monetary valuation of the identified ecosystem services that the wetland provides. Bird watching opportunities, water quality, and flood prevention services are among the highest valued services, while the amenity services are the least valued among all wetland services.

We determine the production risk effects and welfare implications of single-trait Bt corn adoption in the Philippines. We use a stochastic production function estimation approach that allows for examining the skewness effects of Bt within a damage abatement specification. Our results indicate that Bt corn has a statistically significant yield increasing, risk-increasing (i.e., variance-increasing) and downside risk-reducing (i.e., skewness-increasing) effects. Based on risk premium, certainty equivalent, and loss probability welfare measures, Bt corn farmers in the Philippines are better-off (in absolute terms) relative to non-Bt farmers given Bt corn's dominant yield increasing effect and downside risk-reducing effect.
