Beyond the agroecological and sustainable agricultural intensification debate: Is blended sustainability the way forward?

With the sustainable development goals has come a renewed global interest in ending hunger and achieving food security, while preventing natural resource degradation. Despite this renewed interest and increased commitments to invest in agricultural development, there is an outstanding debate over the technological trajectories to sustainability. The debate centres on sustainable agricultural intensification (SAI) and agroecological intensification (AEI) pathways to agricultural sustainability. Using a systematic literature review approach, this study examines the debate over AEI and SAI. This study employs a theoretical framework based on the economic, social, and ecological dimensions of sustainable agriculture within a policy and institutional space. Based on the sustainability dimensions, a discourse analytical technique is applied to unravel the debate. The results reveal differences in actor composition in the SAI and AEI pathways. Both pathways aim to promote food security with optimal and sustainable use of inputs; however, the actors differ on discourse relating to the concept of farming, the role of genetic engineering, the scale of operation, land use and soil health. Resolving these differences requires a blended sustainability approach that moves beyond the current AEI and SAI debate by acknowledging the tradeoffs and synergies of the socio-economic and ecological dimensions.     

Water–milk nexus in India: a path to a sustainable water future?

This paper examines the nexus between milk production and water use in India. The nexus is examined in the context of extended consumptive water use (CWU) of milk production beyond drinking water. It includes the real CWU (evapotranspiration (ETa) that occurs during the production of green fodder and feed grains) and the virtual CWU (ETa embedded in by-products for animal feed). The real CWU appears as large as that of sugarcane, and the real and virtual CWU combined is as large as that of rice. However, milk production generates more value than the outputs of rice and sugarcane combined. Sustainable water use and agricultural growth in major milk-producing areas require a drastic reduction in groundwater CWU, which, at present, exceeds natural recharge. It is suggested that diversifying to a mix of milk and high-value (but low water consuming) crops can reduce groundwater CWU while ensuring higher total output.     

How to assess the impact of hope on a change in the use of land on market value?

This article is devoted to common yet quite specific approaches to valuation practice tasks that are involved in determining the market value of real properties in areas of possible land use changes. An intrinsic element of market value in such areas is the hope value, for which an option pricing model is used quite frequently.The authors propose a specially adapted Samuelson-McKean model for this task, which allows market value indication to be determined not only with the built-in development option, but also the dynamics of its components value in the current highest and best use and hope value – depending on the location of the given property. The greatest advantage of the Samuelson-McKean model is that it can be treated as universal for analyzing the range of possible indications of market value seeing as how its main task is to find a compromise between the interests of the buyer and the seller, which is the goal of any fair transactions and decisions.     

Is a slowdown in agricultural productivity growth contributing to the rise in commodity prices?

A slowdown in the rate of agricultural productivity growth is thought by many observers to be contributing to the recent rise in agricultural prices. In this article I decompose sources of output growth in global agriculture into aggregate input and total factor productivity (TFP) components and examine whether productivity growth slowed substantially in the years leading up to the recent rise in commodity prices. Contrary to widely held perceptions, I find no evidence of a general slowdown in sector‐wide agricultural TFP, at least through 2006. If anything, the growth rate in agricultural TFP accelerated in recent decades. However, the results do show a slowdown in the growth of agricultural investment. Accelerating TFP growth largely offset decelerating input growth to keep the real output of global agriculture growing at about 2% per year since the 1960s. Regionally, however, agricultural productivity performance has been uneven. These findings have important implications for the appropriate supply‐side policy response to the current agricultural price crisis.     

Does willingness to pay increase with the number and strictness of sustainability labels?

Labels signaling sustainable product attributes are gaining importance, although uncertainty concerning the environmental, micro‐ and macroeconomic benefits of such labels persist. One of the questions still incompletely answered is whether Willingness To Pay (WTP) varies with a gradually increasing number of labels on a food product. In order to answer this question, we conducted a laboratory experiment with 191 student respondents, testing consumer valuations of different labeling strategies. Using the Becker‐DeGroot‐Marschak mechanism, WTP for 15 food products was measured. The products were endowed with up to six different sustainability labels, such that each grocery item was available in eight product versions. For perishable, nonperishable, and plant‐based products, the results indicate that participants are prone to allocating WTP‐premiums to labeled products, more than to unlabeled products. For animal products, however, labels do not influence WTP significantly. Furthermore, the premiums do not vary with an increasing number of labels, irrespective of whether the labels signal substitute or complementary sustainability information. The results are not entirely in line with normative notions of magnitude variation, but rather with the behavioral economic concept of embedding effects.     

Is there a future for small farms in developed countries? Evidence from the French case

This research aims to identify the specific characteristics of small farms in developed countries and the factors that influence their survival and growth. Using the case of France, we employ statistical and econometric analysis of data from the Farm Structure Survey (N = 70,000) for the period 2000–2007. The principal findings suggest that small farms are no more likely than other farms to employ “alternative” strategies to the predominant model of increasing farm size, nor are they more likely to diversify on‐farm activities or operate under quality‐labeled production systems, with the notable exception of organic agriculture. However, where small farms do adopt or practice these activities, they are seen to have a favorable effect in ensuring their survival and growth. In contrast, we are unable to conclude that pluriactivity of farm households has a positive impact on the survival of small enterprises. The effect of geographical location on small farms is largely expressed in their concentration in mountainous or disadvantaged regions. Overall, the trajectory of small farms is marked by farm exit, principally as the result of farmers retiring at the end of their careers. The small farm sector is also revitalized by both larger farms declining and thus being reclassified as small farms, as well as the progressive entry into agriculture of small farm holders whose income was previously derived largely off‐farm.     

Is high-tech zone a policy trap or a growth drive? Insights from the perspective of urban land use efficiency

The increasing number of national high-tech zones (NHTZs) in China has triggered significant changes in land use. Several researchers argued that urban land use efficiency (ULUE) may decrease, due to the so-called “development zone fever”. However, using a super-efficient Slacks-based measure (SBM) model and the Double-difference model, we found that, from the perspectives of scale, factor accumulation, and agglomeration effects, NHTZs policies had a positive impact on ULUE in 285 Chinese cities in the period 2003–2016. In addition, the net effects of NHTZs policies on ULUE were 1.13 % in eastern cities, 0.38 % in central cities, and 0.19 % in western cities. Furthermore, different regions experienced differential impacts from economic development, urbanization level, industrial structure, population, foreign direct investment (FDI), and land marketization. A further empirical test found that the cumulative impacts of NHTZs policies on ULUE are related to both quantity and time. Among these, NHTZs growth time had the highest positive impact on ULUE. This study provides empirical justification for the establishment of NHTZs in China.     

The End of a Romance? A Note on the Quantitative Impacts of a ‘Brexit’ from the EU

This study suggests UK equivalent variation (EV) gains of €8.9 billion on withdrawal from the EU budget. Factoring in associated trade facilitation costs from the loss of UK access to the single market, annual UK EV losses could be as high as €14.0 billion, with the EU‐28 facing a corresponding loss of €40.4 billion. Interestingly, the extrapolated UK gain arising from withdrawal from the ‘CAP’ component of the EU budget exceeds estimated lower and upper bound trade facilitation costs exclusively on EU agrofood trade. Accordingly, the UK should realistically remain as an EU member, although continue to lobby for reductions in the CAP budget.     

Is the agricultural industry spared from the influence of the Australian carbon tax?

The Australian agricultural sector provides food security for the nation and affects the livelihood of farmers and the development of rural communities. This sector has been uneasy about the Australian carbon tax scheme introduced in July 2012 although the government has exempted the agricultural sector from the scheme. By employing a computable general equilibrium model and an environmentally extended Social Accounting Matrix, this article simulates the effects of different carbon tax policy scenarios. The modeling results show that all agricultural sectors will be affected negatively but to differing degrees. The household compensation policy will improve the performance of the poultry and fishing sectors, while having opposite effects in the other agricultural sectors. The inclusion of the agricultural industry into the carbon tax scheme will lead to a considerable further decrease in output, employment and profitability in the agricultural sector, and a significant further reduction in real GDP, but a much larger emission reduction.     

Is off-farm income reforming the farm? Evidence from Mexico

Does access to off-farm income complement or compete with agricultural production? This article explores the effect of off-farm income on agricultural production activities, using data from the 2003 Mexico National Rural Household Survey. We first discuss the theoretical conditions under which access to off-farm income may influence production in an agricultural household model. Instrumental-variable (IV) estimation methods are then used to test whether agricultural production activities, technologies, and input use differ between households with and without access to off-farm income. We find that off-farm income has a negative effect on agricultural output and the use of family labor on the farm, but a positive impact on the demand for purchased inputs. There is also a slight efficiency gain in households with access to off-farm income. Findings offer insights into how household production evolves as rural households increasingly engage in off-farm income activities.     

Is it too late to stabilise the global climate?

Assessment of the feasibility of stabilising the global climate requires consideration of trajectories for emissions of carbon dioxide and other greenhouse gases. This study presents a simple and robust analysis of feasible emissions trajectories. Consideration of feasible trajectories suggests that if the current pace of mitigation efforts is sustained, the likely outcome will be stabilisation at concentrations close to 500 parts per million. Such an outcome will imply a higher than 50 per cent probability of substantial damage from climate change and an enhanced risk of a catastrophic outcome.     

How did a network of marine protected areas impact adjacent fisheries? Evidence from Australia

Marine‐protected areas (MPAs) are an effective means of improving habitat quality and biodiversity in the world’s oceans. While the advantages of MPAs as a mechanism for conservation and biodiversity are well established, the potential improvements to fishery performance resulting from a network of MPAs are still being established. Countries around the world have committed to establishing networks of MPAs within their waters by 2020, in response to the United Nations Convention on Biological Diversity. This, coupled with the increasing global demand for seafood and heavy reliance on fishery resources as a source of economic development for many coastal communities, means that an understanding of how these networks can be expected to impact fishery performance is extremely important. We use a difference‐in‐difference modelling approach to isolate the change in the fishery performance associated with the south‐east marine reserve network in Australia. We find no evidence that the economic performance of adjacent fisheries was negatively impacted by the network. This lack of impact is likely due to a network design explicitly intended to avoid effort displacement in key fisheries, along with fishery management changes intended to remove excess fishing capacity.     

Is Bt Cotton a Pro‐Poor Technology? A Review and Critique of the Empirical Record

Policy makers, journalists and other commentators have hailed genetically modified (GM) crops as a ‘pro‐poor’ success in the developing world. Their confidence appears to be justified by the encouraging conclusions reached by academic studies on the performance and impacts of GM crops, which seem to provide convincing evidence of substantial benefits for smallholders in developing countries. However, a detailed, critical examination of studies on transgenic, insect‐resistant cotton in China, India and South Africa demonstrates that the technology's impacts have been evaluated and represented in selective and misleading ways. The performance and impacts of GM crops have in fact been highly variable, socio‐economically differentiated and contingent on a range of agronomic, socio‐economic and institutional factors. The shortcomings of the GM crop‐impacts literature have done a disservice to public and policy debates about GM crops in international development and impeded the development of sound, evidence‐based policy.     

Is a Futures Market Viable in Turkey? The Case of a Cotton Futures Market

Abstract

Many countries as they reduce price controls develop an interest in futures markets as a way to manage risk. This article explores the potential of using existing futures markets to hedge cotton in Turkey. Futures prices in New York and Liverpool are not cointegrated and only weakly correlated with cash prices in Izmir. Thus, existing futures markets have limited ability to reduce the risk faced by the cotton industry in Turkey. While there are obstacles to overcome, there does appear to be a potential demand for a cotton futures market in Turkey.     

What's driving innovation in small businesses in Australia? The case of the food industry

There is strong evidence that innovation is a primary driver of a nation's economic growth. As Australia continues to compete in the global economy, it is imperative that businesses should be innovative to improve their performance. In this paper, we evaluate the status and main drivers of innovation in small businesses in the food sector in Australia. Discrete choice modelling and bootstrapping procedures are applied to a panel of firm‐level data collected through the ABS Business Characteristics Survey (2006–2007 to 2010–2011 for the Australian Bureau of Statistics’ Business Longitudinal Database Confidential Unit Record File) to investigate the factors affecting the likelihood of small food businesses to innovate. Results show that businesses are more likely to innovate if they collaborate, have higher information and communication technology intensity, and use science, technology, engineering and mathematics skills. We also found that small food businesses, even at the subsector level, do combine different types of innovation when innovating. The propensity to innovate also increases for small businesses that have flexible working arrangements, face moderate‐to‐strong market competition, operate overseas and seek finance through debt and equity. The relative importance of these factors was found to vary between agricultural and nonagricultural food subsectors.     

Why is it difficult to enlarge a protected area? Ecosystem services perspective on the conflict around the extension of the Białowieża National Park in Poland

This study explains the difficulties with the enlargement of the Białowieża National Park in Poland through an ecosystem services perspective. We carried out a questionnaire survey among the local communities to investigate local use of ecosystem services and respondents’ attitude towards the national park enlargement. The results indicate that local people are not as dependent on forest resources as often claimed. Firewood proved a crucial resource as the vast majority of the respondents depended on it for heating their houses. We also found that the local population has a rather low awareness of the national park territory and rules involved. The results suggest that previous enlargement attempts might have failed because decision makers did not adequately consider resources the local people depend on. Lack of clear information and transparent decision-making also amplified the conflict. Future enlargement initiatives should provide clear rules concerning the local use of ecosystem services and the access to firewood in particular. Furthermore, new policies should be developed in cooperation with local people and accompanied by an appropriate information campaign. It is argued that the ecosystem services perspective provides important data which can inform more effective conservation policy-making.     

Is Passive Farming A Problem for Agriculture in the EU?

We address a new agricultural policy concern following the decoupling of CAP direct payments in 2005: passive farming, whereby landowners maintain their agricultural area to collect payments without producing commodities. It is claimed that passive farming is hindering agricultural development by ‘blocking’ access to farmland for expanding farmers. We evaluate the links between the EU's Single Payment Scheme (SPS), passive farming, land use and agricultural development. Following identification of the rational landowners’ optimal land‐use choice, we evaluate the effects of the SPS using a spatial, agent‐based model that simulates farmers’ competition for land in a case‐study region of Sweden. We show that passive farming does not constrain land from being used in production; on the contrary more land is used than would be the case without the SPS. We conclude that passive farming is not a problem for agriculture, but provides public goods that would otherwise be under provided: preservation of marginal farmland and future food security. However SPS payments on highly productive land inflate land values (capitalisation) and slow structural change, which hinder agricultural development. Consequently CAP goals could be better served by targeting payments on marginal land and phasing out payments to highly productive land.     

Is there a slowdown in agricultural productivity growth in South America?

This article estimates agricultural productivity growth in 10 South American countries in 1969–2009 with the objective of investigating if the slowdown being measured in other countries is present in the region. Results show that productivity growth accounts for half of the three‐fold increase in agricultural output during this period and that performance is sensitive to R&D investments in the sector. The slowdown found for the 1990s to 2000s in the U.S. and some European economies does not seem to be present yet in South America. The region's total factor productivity (TFP) growth rate increased steadily from 1.07% during the 1970s to 2.29% during the 2000s. Given lags in adoption and the adaptive nature of innovations in these economies, we have yet to see the potential effects in South American agriculture of decreases in R&D in advanced economies.
