Regional food production and land redistribution as adaptation to climate change in the U.S. Northeast Seaboard

Potential corn and winter-wheat grain, and potato crop yields in the United States Northeastern Seaboard Region (NESR) were simulated under current and future climate scenarios and two water management regimes to evaluate production shifts and land-based adaptation methods. Geospatial data consisting of historical climate, land use, soil, and crop management were coupled with a weather generator, three explanatory crop models, and spatially and temporally downscaled mid-century climate change scenarios to conduct the simulations at sub-county spatial resolution. Unadapted winter wheat yield increased 48% in response to mid-century projected climate changes, but corn grain declined 19% and potato 42% across the NESR, resulting in a net loss in caloric production. The contribution of the three crops to regional food production with respect to historical and mid-century climate conditions was evaluated on the basis of caloric content as a measure of yield capacity. The caloric content declined by 7 to 15% across the three commodities when averaged among all states in the region if no adaptation changes were implemented. Two land redistribution schemes were derived to compensate for this loss by re-allocating the existing land-base within each county to specific crops based on model predicted changes in productivity along with identifying additional increments of additional potential land. These approaches showed that less than 1.6% of the potentially available agricultural land base in the region would be needed to compensate for calorie losses due to climate change. These results qualify land redistribution as a pragmatic and direct adaptation strategy to the threat of climate change on regional food security.

Traditional and regional food as seen by consumers – research results: the case of Poland

Purpose This paper seeks to describe the perceptions and motives for acquiring traditional and regional products by Polish consumers. The purpose of this paper is to evaluate the state of regional and traditional food production in Poland and identify the prospects of its development. Design/methodology/approach Both secondary and primary data were used. The sample size included 1,067 respondents selected based on their place of residence and sex. The five-point Likert scale was used to measure the participant attitudes following the construction and validation procedure. Cronbach’s α test was used to evaluate the reliability of the measuring scale, estimated at 0.85, indicating the accuracy of the scales used. Statistica 13 – including t-test, ANOVA and regression analysis – was a software program used to carry out statistical analysis. Prior to the analysis, multivariate normality was examined by testing each variable for normal distribution. Findings The research showed the existence of a statistical relationship between the sex of respondents and the suggested traditional food consumption patterns such as organoleptic qualities, high quality, and finally, curiosity and trying new foods. Sex did not statistically influence the responses for the remaining factors. Originality/value The increased interest in traditional and regional food products is a manifestation of new food-related tendencies and is implied by the desire to exhibit behaviors and values resulting from cultural heritage. Polish consumers are becoming wealthier, better educated, more aware of both tangible and intangible product attributes, and they are having more opportunities to expose their social preferences when shopping. The importance of food attributes such as traditional and regional food certificates, source of origin or the image of the producer (e.g. respecting ethical behavior) is growing. This research is significant not only because of its theoretical input, but its applied value as well.

Questioning the Distinctiveness of the Ukrainian Famine

The collectivisation famines of the 1930s are one of the darkest and most contested chapters in Soviet history. Carried out in the name of agricultural modernisation, Stalin's policy of forced collectivisation led to immense human suffering. Somewhere between 5 to 9 million people are believed to have perished in these famines, with the burden falling disproportionately on several major food-producing regions, including Ukraine, Kazakhstan, the Volga Basin and the Don and Kuban regions of the North Caucasus. Those who survived these terrifying events found their lives transformed, and collectivisation and the accompanying famines played a crucial role in integrating the Soviet Union's vast rural population into the institutions of a ‘workers’ state’.

Screening of Seaweed Degradation Microorganism and Its Agricultural Application

For many years, microorganisms and seaweed have been widely used to increase food production and crop productivity in many regions of the world through its beneficial effects. In the present study, a new process to produce a bioactive extract from the micro fermentation of brown seaweeds was developed. The optimized conditions of pH, inoculum size, seaweed concentration and temperature allowed high extraction yields of alginates represented up to 33% of the seaweeds dry weight, compared to 25% for conventional extraction procedure. Fourier Transform infrared spectroscopy (FTIR) and Gel Permeation Liquid Chromatography (GPC) were used in the alginate characterization, respectively. The sample analyzed had similar infrared absorption peak and molecular weight around 500 kDa of sodium alginate. Furthermore, the antimicrobial activity and influence on plant growth from seaweed fermentation extracts were evaluated. The results demonstrate that the seaweed fermentation extracts may provide a useful tool for the control of different pathogens microorganism and in the same time promote the plant growth.

Optimizing Regional Food and Energy Production under Limited Water Availability through Integrated Modeling

Across the world, human activity is approaching planetary boundaries. In northwest China, in particular, the coal industry and agriculture are competing for key limited inputs of land and water. In this situation, the traditional approach to planning the development of each sector independently fails to deliver sustainable solutions, as solutions made in sectorial ‘silos’ are often suboptimal for the entire economy. We propose a spatially detailed cost-minimizing model for coal and agricultural production in a region under constraints on land and water availability. We apply the model to the case study of Shanxi province, China. We show how such an integrated optimization, which takes maximum advantage of the spatial heterogeneity in resource abundance, could help resolve the conflicts around the water–food–energy (WFE) nexus and assist in its management. We quantify the production-possibility frontiers under different water-availability scenarios and demonstrate that in water-scarce regions, like Shanxi, the production capacity and corresponding production solutions are highly sensitive to water constraints. The shadow prices estimated in the model could be the basis for intelligent differentiated water pricing, not only to enable the water-resource transfer between agriculture and the coal industry, and across regions, but also to achieve cost-effective WFE management.

Comparison of crop yield sensitivity to ozone between open-top chamber and free-air experiments.

Assessments of the impacts of ozone (O3 ) on regional and global food production are currently based on results from experiments using open-top chambers (OTCs). However, there are concerns that these impact estimates might be biased due to the environmental artifacts imposed by this enclosure system. In this study, we collated O3 exposure and yield data for three major crop species-wheat, rice, and soybean-for which O3 experiments have been conducted with OTCs as well as the ecologically more realistic free-air O3 elevation (O3 -FACE) exposure system; both within the same cultivation region and country. For all three crops, we found that the sensitivity of crop yield to the O3 metric AOT40 (accumulated hourly O3 exposure above a cut-off threshold concentration of 40 ppb) significantly differed between OTC and O3 -FACE experiments. In wheat and rice, O3 sensitivity was higher in O3 -FACE than OTC experiments, while the opposite was the case for soybean. In all three crops, these differences could be linked to factors influencing stomatal conductance (manipulation of water inputs, passive chamber warming, and cultivar differences in gas exchange). Our study thus highlights the importance of accounting for factors that control stomatal O3 flux when applying experimental data to assess O3 impacts on crops at large spatial scales.

Improving maize growth processes in the community land model: Implementation and evaluation

Earth system models (ESMs) are essential tools to study the impacts of historical and future climate on regional and global food production, as well as to assess the effectiveness of possible adaptations and their potential feedback to climate. Several current ESMs have the capabilities to simulate crop growth. However, some critical crop growth processes (e.g. flowering and other reproductive processes) and their responses to environmental extremes (e.g. heat stress) are not yet represented in most of these models. In this paper, an improved maize growth model was implemented in the Community Land Model version 4.5 (CLM4.5) by modifying the maize planting scheme, incorporating the phenology scheme adopted from the APSIM model (Agricultural Production Systems sIMulator), adding a new carbon allocation scheme into CLM4.5, and improving the estimation of canopy structure parameters including leaf area index (LAI) and canopy height. Unique features of the new model (CLM-APSIM) include more detailed phenology stages, an explicit implementation of the impacts of various abiotic environmental stresses (including nitrogen, water, temperature and heat stresses) on maize phenology and carbon allocation, as well as an explicit simulation of grain number. Evaluation of results at 7 AmeriFlux sites located in the US Corn Belt show that the CLM-APSIM model performs better than the original CLM4.5 in simulating phenology (LAI and canopy height), surface fluxes including gross primary production (GPP), net ecosystem exchange (NEE), latent heat (LH), and sensible heat (SH), and especially in simulating the biomass partition and maize yield. The CLM-APSIM model corrects a serious deficiency in CLM4.5-related to CLM4.5’s underestimation of aboveground biomass (i.e. overestimation of belowground biomass) and overestimation of Harvest Index, which lead to a reasonable yield estimation with wrong mechanisms. Moreover, 13-year simulation results from 2001 to 2013 at the three Mead sites (US-Ne1, Ne2 and Ne3) show that the CLM-APSIM model can more accurately reproduce maize yield responses to growing season climate (temperature and precipitation) than the original CLM4.5 when benchmarked with the site-based observations and USDA county-level survey statistics. The CLM-APSIM model is thus more suitable than its predecessor models in terms of simulating abiotic environmental stresses on maize yield. This new model provides an improved tool to attribute maize yield change to various processes under historical and future climate, as well as to assess and design effective climate adaptation strategies for sustainable agricultural production.

Assessing Irrigation Aquifer Depletion: Introduction

Assessing Irrigation Aquifer Depletion: Introduction

Calibration and Validation of CSM‐CROPGRO‐Cotton Model Using Lysimeter Data in the Texas High Plains

AbstractTexas High Plains (THP), one of the most important food and fiber producing regions in the Ogallala Aquifer Region, currently faces rapid decline of groundwater levels. Predicted climate extremes and high temporal variability in growing season precipitation may require growers to pump more groundwater from the Ogallala Aquifer to meet higher crop water demand. The Decision Support System for Agrotechnology Transfer (DSSAT) Cropping System Model (CSM) is a widely used crop simulation tool for evaluating impacts of different water and crop management practices, including irrigation on crop yield and water use efficiency. In this study, CROPGRO‐Cotton module of the DSSAT was calibrated and validated using 2000, 2001, 2002, and 2010 irrigated lysimeter field data managed by the USDA‐ARS (United States Department of Agriculture ‐ Agricultural Research Service) Conservation and Production Research Laboratory at Bushland, TX. The lysimeter field consisted of four equal plots designated as NE, SE, NW, and SW. Crop growth characteristics including leaf area index (LAI), above ground biomass (AGB), evapotranspiration (ET), soil moisture, and lint yield of 2000‐NE, 2000‐SE, and 2001‐NE, were used for calibration and 2002‐NE, 2010‐NE, and 2010‐SE were used for validation. The calibrated and validated model was used to simulate the long term (1924–2012) crop yield and seasonal crop ET. During the calibration process, some of the cultivar and ecotype parameters that influence LAI, AGB, and lint yield were adjusted for better statistical results. Measured and simulated LAI, AGB, ET, soil moisture, and lint yield showed good agreement during calibration and validation as indicated by performance statistics such as r2 from 0.70 to 0.82, and percent error (PE) = −0.85 to 17.3% for LAI; r2 = 0.89 to 0.95, and PE = −7.36 to −13.66% for AGB; and r2= 0.90 to 0.94, and PE = 3.20 to 3.44% for ET during calibration and validation, respectively. The model underestimated ET during peak vegetative growth and development stage except in some circumstances. The calibrated and validated model was able to simulate lint yield and seasonal ET during a long term (1924–2012) historic period for Bushland, TX, under irrigated conditions. The calibrated model could be used to schedule ET based irrigation management practices in the THP and to estimate future ET for other modeling experiments.

Assessing the Impact of the EQIP High Tunnel Initiative

This study evaluated the U.S. Department of Agriculture Natural Resources Conservation Service (USDA NRCS) Seasonal High Tunnel Initiative, or HTI, that the USDA expects to strengthen local and regional food production by increasing the availability of fresh, locally grown food. Goals of the HTI include improved plant and soil quality, reduced nutrient and pesticide run­off, and increased availability of fresh vegetables and fruits for local food markets. This study explored the farm-level impacts of production via high tunnels among Indiana farmers relying on the infrastructure. We identify characteristics of farmers who have obtained high tunnels through the cost-share program, to better understand the types of farm enterprises that are using the HTI to date and the effects that high tunnel implementa­tion may have on their farms’ economic success and contributions to locally sourced food systems. Overall, results indicate that high tunnel users are able to extend the growing season, improve their farm’s economic stability, and increase the quality and yield of their crops. Our survey also finds that those farmers who have self-funded all or a portion of their high tunnels report greater increases in their farm’s economic stability from investing in high tunnels than farmers relying on the NRCS funds for their high tunnels.

Trading off natural resources and rural livelihoods. A framework for sustainability assessment of small-scale food production in water-limited regions

Enhancing local production is key to promoting food security, especially in rural households of low-income countries, but may conflict with limited natural resources and ecosystems preservation. We propose a framework integrating the water-food nexus and a sustainable livelihoods perspective to assess small-scale food production in water-poor regions. We demonstrate it by assessing alternative production scenarios in the Gaza Strip at different spatial scales. At the scale of a single farm, there is a clear conflict among objectives: while cash crops ensure good incomes but contribute scarcely to domestic protein supply, crops performing well from the nutritional and environmental viewpoint are among the worst from the economic one. At the regional scale, domestic production might cover an important fraction of nutritional needs while contributing to household income, but water scarcity impairs the satisfaction of food demand by domestic production alone. Pursuing food security under multiple constraints thus requires a holistic perspective: we discuss how a multidimensional approach can promote the engagement of different stakeholders and allow the exploration of trade-offs between food security, sustainable exploitation of natural resources and economic viability.

Hydropower versus irrigation—an analysis of global patterns

Numerous reservoirs around the world provide multiple flow regulation functions; key among these are hydroelectricity production and water releases for irrigation. These functions contribute to energy and food security at national, regional and global levels. While reservoir operations for hydroelectricity production might support irrigation, there are also well-known cases where hydroelectricity production reduces water availability for irrigated food production. This study assesses these relationships at the global level using machine-learning techniques and multi-source datasets. We find that 54% of global installed hydropower capacity (around 507 thousand Megawatt) competes with irrigation. Regions where such competition exists include the Central United States, northern Europe, India, Central Asia and Oceania. On the other hand, 8% of global installed hydropower capacity (around 79 thousand Megawatt) complements irrigation, particularly in the Yellow and Yangtze River Basins of China, the East and West Coasts of the United States and most river basins of Southeast Asia, Canada and Russia. No significant relationship is found for the rest of the world. We further analyze the impact of climate variables on the relationships between hydropower and irrigation. Reservoir flood control functions that operate under increased precipitation levels appear to constrain hydroelectricity production in various river basins of the United States, South China and most basins in Europe and Oceania. On the other hand, increased reservoir evaporative losses and higher irrigation requirements due to higher potential evaporation levels may lead to increased tradeoffs between irrigation and hydropower due to reduced water availability in regions with warmer climates, such as India, South China, and the Southern United States. With most reservoirs today being built for multiple purposes, it is important for policymakers to understand and plan for growing tradeoffs between key functions. This will be particularly important as climate mitigation calls for an increase in renewable energy while agro-hydrological impacts of climate change, population and economic growth and associated dietary change increase the need for irrigated food production in many regions round the world.

Peri-Urban Food Production and Its Relation to Urban Resilience

Food production on the urban–rural fringe is under pressure due to competing land uses. We discuss the potential to improve resilience for urban–rural regions by enhancing food production as part of multifunctional land use. Through studies of peri-urban land in the regions of Gothenburg (Sweden), Copenhagen (Denmark) and Gent (Belgium), recent developments are analysed. Arable farming has been declining since 2000 in all three areas due to urban expansion and recreational land use changes. In city plans, networks of protected areas and green spaces and their importance for human wellbeing have been acknowledged. Policies for farmland preservation in peri-urban settings exist, but strategies for local food production are not expressed in present planning documents. Among the diversity of peri-urban agricultural activities, peri-urban food production is a developing issue. However, the competing forms of land use and the continuing high dependence of urban food on global food systems and related resource flows reduces peri-urban food production and improvements in urban food security. The positive effects of local food production need to be supported by governance aiming to improve the urban–rural relationship. The paper discusses the resilience potential of connecting urban–rural regions and re-coupling agriculture to regional food production.

Getting Road Expansion on the Right Track: A Framework for Smart Infrastructure Planning in the Mekong.

The current unprecedented expansion of infrastructure promises to enhance human wellbeing but risks causing substantial harm to natural ecosystems and the benefits they provide for people. A framework for systematically and proactively identifying the likely benefits and costs of such developments is badly needed. Here, we develop and test at the subregional scale a recently proposed global scheme for comparing the potential gains from new roads for food production with their likely impact on biodiversity and ecosystem services. Working in the Greater Mekong—an exceptionally biodiverse subregion undergoing rapid development—we combined maps of isolation from urban centres, yield gaps, and the current area under 17 crops to estimate where and how far road development could in principle help to increase food production without the need for cropland expansion. We overlaid this information with maps summarising the importance of remaining habitats to terrestrial vertebrates and (as examples of major ecosystem services) to global and local climate regulation. This intersection revealed several largely converted yet relatively low-yielding areas (such as central, eastern, and northeastern Thailand and the Ayeyarwady Delta), where narrowing yield gaps by improving transport links has the potential to substantially increase food production at relatively limited environmental cost. Concentrating new roads and road improvements here while taking strong measures to prevent their spread into areas which are still extensively forested (such as northern Laos, western Yunnan, and southwestern Cambodia) could thus enhance rural livelihoods and regional food production while helping safeguard vital ecosystem services and globally significant biological diversity.

Mixing trees and crops increases land and water use efficiencies in a semi-arid area

Sustainable increases in food production in semi-arid regions require efficient use of land and water resources. Agroforestry is the practice of combining tree and crop cultivation on a land parcel and may increase both land productivity and water use efficiency. We conducted two years of field experiments in the semi-arid Khorchin region in Liaoning, China, to determine to which extent land and water use efficiencies were affected by mixing apricot (Prunus armeniaca) trees with annual crops: peanut (Arachis hypogaea), millet (Pennisetum italica) or sweet potato (Ipomoea batatas). Apricot yields were not significantly affected in the agroforestry, compared to the sole stand, but yields of the annual crops were lower when grown under trees than as sole crops, with relative crop yields of 0.46 for millet and 0.35 for both peanut and sweet potato in the agroforestry. Crop rows near tree rows had lower yields than crop rows further away from trees. Land equivalent ratios (LER) were 1.34, 1.44 and 1.33 in mixed systems with peanut, millet and sweet potato, respectively. Mixing crops and trees did not increase water extraction from the top 100 (2012) or 200cm (2013) soil profile comparing to sole tree. Thus, with increased crop output and similar apricot yield, the water use efficiency was improved in the mixed system. Water use efficiency of the mixed system was characterized with the water equivalent ratio (WER). This index, analogous to LER, expresses the relative yield total per unit of water in the mixed system compared to the sole crops. WERs were 1.39, 1.51, and 1.34 in agroforestry systems with peanut, millet and sweet potato, respectively. We conclude that apricot-based agroforestry improves the productivity and water use efficiency of rain-fed agriculture in this semi-arid area, especially when a drought adapted crop such as millet is used.

Climate Change Perceptions of NY State Farmers: The Role of Risk Perceptions and Adaptive Capacity.

Climate change is expected to severely impact agricultural practices in many important food-producing regions, including the Northeast United States. Changing climate conditions, such as increases in the amount of rainfall, will require farmers to adapt. Yet, little is known with regard to farmers' perceptions and understandings about climate change, especially in the industrialized country context. This paper aims at overcoming this research limitation, as well as determining the existing contextual, cognitive, and psychological barriers that can prevent adoption of sustainable practices of farmers in New York State. The study is framed within the adaptive capacity and risk perception literature, and is based on a qualitative analysis of in-depth interviews with farmers in 21 farms in two counties in Central New York. The results reveal diverging views about the long-term consequences of climate change. Results also reveal that past experience remains as the most important source of information that influences beliefs and perceptions about climate change, confirming previous research.

Hydroponics: potential for augmenting sustainable food production in non-arable regions

Purpose The purpose of this review of the literature is to provide readers a foundation of understanding whereby future research can move forward in the quest for global sustainable food production. Design/methodology/approach This review includes up-to-date information from evidence-based sources on hydroponics. Topics included are advantages, limitations, nutritional quality and sensory quality Findings Hydroponic growing systems offer the opportunity to at least augment traditional soil-based growing systems in global food production. Some benefits of hydroponic growing systems are limitation of water waste (recirculation), crops grown in controlled environments (control of pests, nutrients and attributes required for optimal plant growth) and ability to manipulate conditions to maximize production in limited space (vertical gardens). Practical implications The human population is increasing with a parallel increase in the demand for food; therefore, food production must increase to meet the need. Originality/value In spite of the rapid interest and proliferation of information by laypeople, evidence-based research is scant on hydroponics. This article provides a summary of the literature on hydroponics and how it may be used for sustainable food production in arid and urban areas.

Groundwater use and policy options for sustainable management in Southern Iraq

An important challenge facing the design of sustainable aquifer management plans is weak primary data on aquifer recharge and use patterns. Weak data limit the ability of policy makers to design efficient aquifer protection plans. The objectives of this article are (1) to estimate groundwater use patterns for an important food-producing region of southern Iraq, the Bahr Al-Najaf Basin; (2) to compare groundwater use patterns with the renewable groundwater supply; and (3) to describe a sustainable groundwater policy alternative to current use patterns. For this study, original data on groundwater pumping were secured for 2006–2011. The data show a pattern of unsustainable groundwater withdrawals. A policy intervention is described in which pumping permits could be assigned to groundwater users to promote sustainable use. Allowing or encouraging the permits to be transferable through trading to higher-valued uses could reduce the economic costs of protecting the aquifer while promoting its sustainable use.

Interactive Fuzzy-Boundary Interval Programming for Water Resources Management of the Hetao Basin, China

AbstractIn this study, an interactive fuzzy-boundary interval programming (IFBIP) method is developed to plan water resources management under uncertain conditions. IFBIP is capable of addressing dual uncertainties expressed as fuzzy-boundary intervals, as well as analyzing the reliability of satisfying (or the risk of violating) various constraints. The IFBIP method is then applied to the water resources management of the Hetao Basin (located in Inner Mongolia, China), one of the largest irrigation areas and the main food-producing region in the Yellow River Basin, where water scarcity is a major constraint for socioeconomic development. Results of water-allocation pattern and system benefit have been obtained under different feasibility degrees. Results reveal that agricultural irrigation is still the largest water consumer, compared with the other users such as industry, municipality, and livestock; meanwhile, irrigation water in each subarea is mainly from the Yellow River over the planning horizon.
