Are maize marketers averse to quality loss in supplies? A case study from Ghana

To ensure sustainable post‐harvest loss reduction, markets that are averse to quality loss and provide incentives for farmers to supply high quality produce are crucial. Such markets will be averse to quality loss, offering distinct prices and substantial rewards to farmers for the supply of quality produce. Farmers in sub‐Saharan Africa (SSA), where informal markets exist, have often assessed the rewards for the supply of quality produce as inadequate. Hence, this study investigates if intermediary buyers are actually indifferent to quality loss in supplies based on two scenarios—the informal market scenario and a hypothesized grade scenario. The analysis builds on survey data from marketers in two informal maize markets in Ghana. For the hypothesized grade scenario, random effect regression was used to examine the influence of marketer‐specific characteristics on premiums offered to farmers over different quality levels. The findings suggest that although informal markets seem not to adequately value loss reduction, investing in institutional infrastructures, such as grades and standards can change this. Furthermore, interaction among marketers and association participation positively influences the value marketers place on quality loss reduction. The result highlights the importance of standard grading systems and collaborating with market groups in minimizing quality loss.     

Does demographic change affect land use patterns?: A case study from Germany

Recent demographic change, mainly characterised by a decreasing and ageing population, is seen as one of the main factors for future land use development in Europe. However, there is still insufficient evidence about the relationship between demographic changes and land use changes since quantitative studies dealing with these interactions are still rare. We aim to fill that gap by presenting the first comprehensive study that investigates statistical relationships and spatial differentiations between demographic and land use change for the whole of Germany. Our study is based on data for the period from 1995/1996 to 2003/2004. The results clearly show that in most growing regions in the West of Germany a correlation was found between land use, natural population growth and net-migration, whereas for land use change in the shrinking regions in the East of Germany economic variables are of noticeable importance. A cluster analysis reveals “gaining” and “shrinking” regions concerning both urbanisation and demographic change. Neither a decreasing nor an ageing population imply reduced land consumption for housing and transportation. Furthermore we found a decreasing settlement population density for almost all German districts regardless of population growth or shrinkage.     

Land consolidation – A great need to improve effectiveness. A case study from Poland

Among the different factors which have an influence on the profitability of small and medium-size farms, a very significant and sometimes even crucial role is played by the unfavourable parameters of land fragmentation (LF). However, this adverse limiting factor can be improved in a relatively short time through land consolidation (LC) treatment. The financial support of these kinds of activities is one of the main aspects of the Common Agricultural Policy (CAP), which aims to equalise the conditions for farming production. Since accession to the EU in 2004, Poland is one of the biggest beneficiaries of various financially-supported projects oriented to the development of rural area, where LC work takes a special position.This paper sums up the outcomes of the LC work that was undertaken in Poland over the period 2007–2013. The results of the investigation delivered the information about the effectiveness of LC work at the farm level. Also, the efficiency of the existing funding strategy of LC work was evaluated. Additionally, the findings revealed poor effects of land swapping and re-parcelling activities, which is disturbing bearing in mind the financial scale and the amount of time spent conducting these actions. As a remedy, several solutions for improvement of the inefficient LC proceedings were proposed.     

Transdisciplinary landscape planning: Does the public have aspirations? Experiences from a case study in Ghent (Flanders,Belgium)

Since the end of the last century, the focus in landscape policy is shifting from traditional top-down perspectives into a bottom-up and integrated approach involving participation of local stakeholders. Keywords in the European Landscape Convention (ELC) include participation and awareness-raising: the public should be involved and their aspirations towards landscape should be assessed. This evolution in policy went with a new paradigm in landscape research: transdisciplinarity. Despite this evolution, literature indicates the necessity of a more general use of methods for public participation in landscape planning to meet the objectives of the Convention. The present paper explores ways to involve ‘the local people’ and to grasp their aspirations with regard to the landscape features of their surroundings. Point of departure is a questionnaire combining questions on landscape preference, environmental worldview and behaviour in the landscape. The questionnaire was distributed in a spatially stratified sample amongst inhabitants of the city of Ghent. The survey was set up without any connection to a concrete operational project that could convince respondents to participate. The response rate was relatively large despite a rather demanding questionnaire. More isolated target groups such as people with lower income, lower education level, and retired people were included, but foreigners, despite being a substantial part of the urban population, did not respond. The respondents appeared to be rather homogeneous as regards environmental worldview and aspirations in the landscape. It appeared that environment and landscape were not clearly distinguished between by the respondents. These results yield some suggestions for transdisciplinary landscape policy. A careful design of the sampling can enhance number and diversity of the respondents. Yet, it is equally important to develop a common language to communicate about landscape so that the question items can be clearly phrased and understood. Aspirations towards landscape should be defined more unambiguously so that they can be assessed alike. Awareness-raising for landscape may help to increase the number of local people that feel addressed when talking about landscape. When public support for landscape policy and management is taken seriously, more factors than only landscape should be taken into consideration.     

Does organic farming (OF) work in favour of protecting the natural environment? A case study from Poland

Organic farming (OF) is a management system that is closely linked with the quality of the natural environment since it should, besides producing organic food, constitutes a protective factor for all components of that natural environment. Therefore, the objective of this paper was to answer the following question: Does organic farming (OF) protect the natural environment? In order to achieve this goal it was essential to determine what kinds of natural and non-environmental factors have the largest influence on the development of OF in Poland, and to assess the significance of these factors in the spatial diversification of the regional density of organic farms. The analysis was carried out on the basis of data from 2012 comprising 2074 communes, including both rural communes (1563) and urban-rural ones (511). The research results indicated the weaknesses of the organic farming policy (OFP) with respect to the functioning of OF in Poland in the years 2007–2013. The results also show that the development of OF in Poland mainly depends on the system of financial support, i.e. one that either encourages farmers to change the manner of production to a more environmentally friendly one, or one that has an impact on their decision to resign from production using ecological methods. Moreover, as our research has proved, OF is not always developed in places where it should be a priority because of the suitable conditions of the natural environment.     

Can carbon-trading schemes help to protect China's most diverse forest ecosystems? A case study from Xishuangbanna,Yunnan

Xishuangbanna has been largely transformed from biodiverse natural forests and mixed-use farms into monoculture rubber plantations in just twenty years. This conversion has expanded into forests previously protected by the community and onto marginal sites at high-elevation. Market-based ecosystem payments, especially carbon financing, are potential tools to prevent further forest loss in China. Here, we compare rubber net present value (NPV), carbon sequestration, and seed-plant species diversity for Xishuangbanna given three land-use scenarios: Business-As-Usual (BAU), Economic Oriented Scenario (EOS) and Conservation Oriented Scenario (COS) using a previously published spatial map of rubber profitability. The EOS achieved the greatest rubber profit but caused substantial reductions in natural forest area, biodiversity and carbon stocks. The EOS also requires substantial immigration of workers into a remote and ecologically important region with little social infrastructure for basic security, food security, health-care and education, causing frequently ignored costs. As expected, the COS will maintain the highest levels of natural forest area, sequester 57% more carbon, and 71% more biodiversity than EOS. Given the conservation value of the carbon stores and rich biodiversity residing in Xishuangbanna's natural forests, reducing rubber NPV only marginally would probably cost less than attempting to recover these resources. We recommend that rubber plantations be limited to established, productive lowland areas whilst protecting intact high-elevation forest and reforesting low-productivity plantations. These actions will enhance carbon sequestration and biodiversity conservation. Management policies focused solely on profits, like the EOS scenario, will fail to sustain the entire range of natural resources and ecosystem services. The prices in the carbon market would have to be considerably larger than they are currently to compete with the profitability of rubber.     

Does labor migration affect rural land transfer? Evidence from China

Land transfer in rural areas and labor migration from rural areas to cities are both becoming common in China due to the increasing development of the non-agricultural sector resulting from rapid urbanization. Many rural labours who migrated to cities left their land in rural areas, and in most cases, this land was abandoned. To make full use of abandoned land in rural areas, the central government in China has formulated policies to promote rural land transfer, but rural land transfer still lags far behind labor migration in China. Drivers of rural land transfer still need to be explored. In addition, the labor migration scale shows dynamic features as the labor migration of more family members is substituted for that of individuals recent years. Thus, the phased feature of household labor migration should be taken into consideration to examine the phased influence of the labor migration scale on rural land transfer. Considering the probability threshold effect of the impact of labor migration on rural land transfer, a threshold model was used to perform the empirical analysis. Based on the threshold model and CHARLS 2015 data, this study empirically analysed the impact of the labor migration scale on rural land transfer. On the national level, labor migration will significantly promote rural land transfer if it is less than or equal to 0.125, but when it is greater than 0.125, its impact on land transfer is not significant. On the basis of the spatial differentiation of rural land transfer, four regions were divided to do the regional threshold regression analysis. On the regional level, the thresholds of labor migration scale of the central region, the east region and the west region are 0.112, 0.221 and 0.133 respectively, and there is no threshold in the north region. The results show that labor migration have a phased impact on rural land transfer in China and policies should be targeted to different labor migration phases and different regions.     

Does maternal employment affect child nutrition status? New evidence from Egypt

Even though maternal employment can increase family income, several studies suggest that it could have adverse consequences on children’s health. In this study, we use a nationally representative sample of 12,888 children, aged 0–5 years from Egypt to examine the impact of maternal employment on child nutritional indicators, namely: stunting, wasting, and being underweight and overweight. We adopted various estimation methods to control for observable and unobservable household characteristics in order to identify the causal effect of maternal employment. These different techniques include, propensity score matching (PSM), OLS regression with controlling for a wide range of individual characteristics, and an instrumental variable two-stage least squares (IV 2SLS) approach. Results of the PSM and OLS suggest that maternal employment is weakly associated with having a malnourished child. On the other hand, the IV 2SLS suggests a stronger and significant association between maternal employment and poor nutritional status among children.     

Is spatial planning a collaborative learning process? A case study from a rural–urban gradient in Sweden

International and national policies stress the importance of spatial planning for the long-term sustainability of regions. This paper identifies the extent to which the spatial planning in a Swedish region can be characterised as a collaborative learning process. By combining qualitative interviews and systems thinking methods we analysed the main attributes of public-led spatial (i.e. comprehensive) planning in nine municipalities representing a steep urban–rural gradient in the Bergslagen region of Central Sweden. We show that the attributes of strategic spatial planning needed for collaborative learning were absent or undeveloped. All studied municipalities experienced challenges in coordinating complex issues regarding long-term planning to steer territorial development and help to solve conflicts among competing interests. Stakeholder participation was identified as a basic condition for social learning in planning. Together with stakeholders we identified the causal structure behind stakeholder participation in municipal planning processes, including main drivers and feedback loops. We conclude that there is a need for arenas allowing and promoting stakeholder activity, participation and inclusion that combines both bottom-up and top-down approaches, and where evidence-based collaborative learning can occur.     

Sustainable rural communities? A legal perspective on the community right to buy

Sustainable development is the underlying policy behind the community right to buy land in rural Scotland enshrined in the Land Reform (Scotland) Act 2003, Part 2. The Act explicitly requires communities wishing to exercise the right to buy to have sustainable development at the heart of their community body and all their plans for the land. This paper examines the role and interpretation of sustainable development in the CRB. Since the Act was passed three administrations have headed up the Scottish government and sustainable development issues and strategies for Scotland have been aired in four important and distinctive policy documents showing that it is still very much an evolving concept in Scottish politics. The current administration has adopted the most econocentric approach yet seen in the UK, focusing on sustainable economic growth. Meanwhile, the community right to buy has developed its own sustainable development agenda. This review of decisions taken under the legislation illustrates that a diverse range of community ownership plans have been deemed consistent with sustainable development, from creation of sports facilities to preservation of castles, lighthouses and village greens. A range of economic, social and environmental objectives have been approved. On the other hand, communities that fail to adopt the ‘right’ approach to the principle will not be successful in using the legislation.     

Does the spatial representation affect criteria weights in environmental decision-making? Insights from a behavioral experiment

The need and interest to consider cognitive and motivational biases has been recognized in different disciplines (e.g. economics, decision theory, risk analysis) and has recently reached environmental decision-making. Within this domain, the intrinsic presence of a spatial dimension of both alternatives and criteria calls for the use of maps throughout the decision-making process to properly represent the spatial distribution of the features under analysis. This makes spatial Multi Criteria Decision Analysis (MCDA) a particularly interesting domain to explore new dimensions of cognitive biases. This study proposes a behavioral experiment aimed at discovering to what extent the spatial visualization (i.e. maps) of criteria versus the non-spatial one (i.e. tables) can bias the weight elicitation phase of a spatial MCDA process. The experiment simulates a very common analysis in environmental and land use planning: land suitability analysis. Our findings show that there are significant consequences on how important we perceive a certain criterion to be, depending on whether it is represented as a map or as a table among a mix of maps and tables. Indeed, the map representation of the same criterion leads to higher weights attributed to that criterion compared to the table representation. Visualizing the same information as a map or as a table, although technically equivalent, is thus not psychologically equivalent for Decision Makers. The results of this experiment are expected to have implications for spatial decision-making processes, by generating better awareness on the impacts of map-mediated land suitability analysis.     

Is public investment complementary to private investment in Indian agriculture? Evidence from NARDL approach

The issue of complementarity between public farm investment and private farm investment in Indian agriculture is an unsettled empirical question in the literature, which has not been studied adequately. Few studies analyzing the trends of both types of investments have produced contradictory results. Thus, this study attempts to bridge that gap, by examining the hypothesis of crowding‐in/crowding‐out effect of public sector investment on private investment. Time series data for a period of 45 years from 1971 to 2015 has been used. Adopting a ‘nonlinear auto‐regressive distributive lag’ (NARDL) model the study confirms a strong crowding‐in effect of public investment on private investment in short run, but relatively a weak complementarity between the two over long‐run. Moreover, the public canal intensity as a major component of public investment has been observed to have much stronger effect on private investment than the public investment itself. It is also found that private investment is constrained by its own lagged values, institutional credit and terms of trade during both short‐run and long‐run. The policy suggestion of this study calls for an immediate arrest of declining trend of public investment.     

Does fertilizer use respond to rainfall variability? Panel data evidence from Ethiopia

In this article, we use farmers' actual experiences with changes in rainfall levels and their responses to these changes to assess whether patterns of fertilizer use are responsive to changes in rainfall patterns. Using panel data from the Central Highlands of Ethiopia matched with corresponding village‐level rainfall data, the results show that the intensity of current year's fertilizer use is positively associated with higher rainfall levels experienced in the previous year. Rainfall variability, on the other hand, impacts fertilizer use decisions negatively, implying that variability raises the risks and uncertainty associated with fertilizer use. Abundant rainfall in the previous year could depict relaxed liquidity constraints and increased affordability of fertilizer, which makes rainfall availability critical in severely credit‐constrained environments. In light of similar existing literature, the major contribution of the study is that it uses panel data to explicitly examine farmers' responses to actual weather changes and variability.     

Does reading scenarios of future land use changes affect willingness to participate in land use planning?

Scenarios of future outcomes often provide context for policy decisions and can be a form of science communication, translating complex and uncertain relationships into stories for a broader audience. We conducted a survey experiment (n = 270) to test the effects of reading land use change scenarios on willingness to participate in land use planning activities. In the experiment, we tested three combinations of scenarios across two time periods, comparing survey responses of individuals reading a set of scenarios with individuals who did not read scenarios. Reading scenario narratives increased willingness to participate in land use planning activities and perceived self-efficacy. Measures of interest and sense of community also increased willingness to participate. Tests of an indirect mediation model found self-efficacy partially mediated the effect of reading scenarios on willingness to participate. This latter relationship may be a mechanistic explanation for the effect of reading scenarios. Envisioning the future with brief, bulleted scenarios of land use change in a print format appears to increase self-efficacy in planning for the future. Our results suggest scenarios can serve as a vehicle for changing public participation in land use planning.     

Does extensification lead to enhanced provision of ecosystems services from soils in UK agriculture?

Extensification is offered as a management strategy to reduce the perceived negative effects of intensive agricultural management, e.g. nutrient loss through leaching, emissions of the greenhouse gas N₂O, loss of soil carbon through carbon dioxide emissions, increased nutrient, carbon and sediment loading to surface water, and reduced biodiversity. As part of managed extensification implemented under the European Union's Common Agricultural Policy intensively managed land use types (arable and grassland) are taken out of production for either 5, 7 or 10 years in the UK. The ultimate objective is to establish species-rich grassland (SRG) to which limited or no fertiliser is applied, which attracts subsidy payments under the European Agricultural Fund for Rural Development. There is little scientific evidence for the anticipated environmental benefits of these newly created SRGs. The legacy of intensive management on soils is likely to limit ecosystem service (ES) provision from former intensively managed sites for many decades following extensification and this commentary addresses this issue. Clearly, programmes of long-term experimental research are needed to quantify the environmental and economic benefits of current extensification schemes in UK agriculture in order to determine whether the benefits for ES delivered by soils out-weigh the costs in terms of loss of production.     

Do native and invasive labels affect consumer willingness to pay for plants? Evidence from experimental auctions

Ornamental plant sales have been identified as an important vector for the introduction of invasive plants. Increased concerns about the economic and ecological costs of invasive plants have spawned interest in identifying strategies to curtail introductions. One possible strategy is labeling plants based on whether they are invasive or native. The primary purpose of this paper was to explore how labeling plants based on invasive and native attributes might affect consumer demand. To accomplish this objective, a second price auction was used to elicit the willingness to pay (WTP) for plants with and without labels. On average, we found a $0.35 premium for plants labeled as noninvasive and native and a $1.01 to $1.66 discount for plants labeled as invasive. The size of these premiums and discounts differed in relation to various demographic, attitudinal, and preference‐related factors. Overall, our results suggest that labeling plants as invasive or native could be a viable strategy for reducing the introduction of invasive plants.     

Does timing matter? A real options experiment to farmers' investment and disinvestment behaviours

In this article, we analyse the (dis)investment behaviour of farmers in a within‐subject designed experiment. We ascertain whether, and to what extent, the real options approach (ROA) and the classical investment theory can predict farmers' (dis)investment behaviour. We consider a problem of optimal stopping, stylising an option to (dis)invest in agricultural technology. Our results show that both theories do not explain exactly the observed (dis)investment behaviour. However, some evidence was found that the ROA predicted the decision behaviour of farmers better than the classical investment theory. Moreover, we found that farmers learn from repeated investment decisions and consider the value of waiting over time. Socio‐demographic and farm‐specific variables also affect the (dis)investment behaviour of farmers.     

Identifying and mapping the tourists⿿ perception of cultural ecosystem services: A case study from an Alpine region

Landscapes provide an array of services to society, from the provision of food and material, to the provision of cultural ecosystem services such as recreation, aesthetics or spirituality. Studies on cultural ecosystem services, however, remain rare and little is known about the spatial localisation of these services. In this study, we adopt and test a framework to identify and map the provision of cultural ecosystem services as perceived by tourists in an Alpine region, i.e. the region of South Tyrol in Italy. A photo-based questionnaire survey is combined with cartographical representations of landscape types to elicit hot and coldspot areas of cultural ecosystem service provision. We statistically test for influences of the land use type and the respondents' socio-demographic background on the tourists' perception of these services. The results show that different spatial patterns emerge for each of the investigated cultural ecosystem services depending on the distribution and extent of the landscape types to which they are related. In particular traditionally managed landscapes, small in extent and mainly scattered over large areas between 1000 and 2200 m a.s.l., are hotspot areas of aesthetic beauty, leisure activities and spirituality. In contrast, intensively managed landscapes, mainly located in the lowland plains of the study site, are considered to be more important for the provision of cultural heritage values. While the results suggest that land use type exerts the strongest influence upon tourists' perception, factors such as the respondents' perceived importance of the services, their gender, cultural background, environmental engagement and experience with the landscape play a significant but subordinate role. We conclude that the spatially explicit information about the provision of cultural ecosystem services can serve as a helpful basis for the design and further implementation of land use policies that acknowledge the high touristic value of traditionally used landscapes in mountain regions.     

Does carbon farming provide a cost‐effective option to mitigate GHG emissions? Evidence from China

In this study, we apply a whole farm bioeconomic analysis to explore the changes in land use, farm practices and on‐farm greenhouse gas (GHG) emission under varying levels of agricultural greenhouse gas abatement incentives in the form of a carbon tax for a semi‐arid crop‐livestock farming system in China's Loess Plateau. Our results show that the optimised agricultural enterprises move towards being cropping‐dominated reducing on‐farm emission since livestock perform is the major source of emission. Farmers employ less oats‐based and rapeseed‐based rotations but more dry pea‐based rotations in the optimal enterprise mix. A substantial reduction in on‐farm greenhouse gas emission can be achieved at low cost with a small increase in carbon incentives. Our estimates indicate that crop‐livestock farmers in China's Loess Plateau may reduce their on‐farm GHG emission between 16.6 and 33 per cent with marginal abatement costs <￥100/t CO₂e and ￥150/t CO₂e in 2015 Chinese Yuan. The analysis implies that reducing greenhouse gas emission in China's semi‐arid crop‐livestock agriculture is potentially a low‐cost option.     

Does access to improved grain storage technology increase farmers' welfare? Experimental evidence from maize farming in Ethiopia

Seasonal price variability for cereals is two to three times higher in Africa than on the international reference market. Seasonality is even more pronounced when access to appropriate storage and opportunities for price arbitrage are limited. As smallholder farmers typically sell their production after harvest, when prices are low, this leads to lower incomes as well as higher food insecurity during the lean season, when prices are high. One solution to reduce seasonal stress is the use of improved storage technologies. Using data from a randomised controlled trial, in a major maize-growing region of Western Ethiopia, we study the impact of hermetic bags, a technology that protects stored grain against insect pests, so that the grain can be stored longer. Despite considerable price seasonality—maize prices in the lean season are 36% higher than after harvesting—we find no evidence that hermetic bags improve welfare, except that access to these bags allowed for a marginally longer storage period of maize intended for sale by 2 weeks. But this did not translate into measurable welfare gains as we found no changes in any of our welfare outcome indicators. This ‘near-null’ effect is due to the fact that maize storage losses in our study region are relatively lower than previous studies suggested—around 10% of the quantity stored—likely because of the widespread use of an alternative to protect maize during storage, for example a cheap but highly toxic fumigant. These findings are important for policies that seek to promote improved storage technologies in these settings.
