Abstract: | To achieve food security for all, new resource policies for sustainable land and water use are needed. Land, water and energy need to be considered jointly in policies, not in isolation. G20 countries' policy makers, corporate and civil society actors, and those of other countries should act in coordinated fashion in the following four policy areas on which specific proposals are made in this policy paper: 1) focusing land, and water resource policies on human wellbeing, 2) investing in and sharing water, agricultural and energy innovations, 3) making wider use of digital opportunities for sustainable agriculture, and 4) re-designing global governance of agriculture and food. |

Abstract: | Based on a novel, detailed, time-consistent tariff database to take stock of developments regarding import protection in the agricultural sector since 2001, we propose a statistical decomposition of the changes in the various types of tariffs. The results show that the multilateral system has played a limited role in trade liberalization over the period. Many countries have continued to apply much lower tariffs on agricultural products than their WTO ceilings. Moreover, there has been substantial unilateral dismantling of tariffs over the period, so that much of the liberalization took place outside WTO and regional agreements. The number of regional trade agreements has surged, but their impact on applied agricultural tariffs has been limited. Finally, we investigate the tariffs, trade and production implications for food and agricultural products of two extreme scenarios in the future development of trade negotiations: an ambitious surge of regional agreements and a trade war within the WTO context. |

Abstract: | The contribution of biofuels to save greenhouse gas emissions has been challenged over the last years. A still unresolved question is how to quantify emissions from indirect land use change (iLUC). In this article we discuss the implications of uncertainties on the current policy proposals in the European Union (EU). We conclude that it is inappropriate to calculate crop-specific iLUC-emissions and to include them into binding regulation. We argue that modelling results, particularly crop-specific ones, should not be used for policy decisions. Our discussion of the current EU policy proposal suggests that a combination of an increase in the minimum emissions savings threshold and limits to biofuel production are a safe way to ensure with a high degree of certainty a climate mitigation impact of biofuels. |

Abstract: | This paper attempts to address the impact of the MGNREGA on the rural agricultural sector, focusing on cropping patterns, irrigated area, crop yields, wages and rural employment. The analysis is based on two data sources- the first is a unique district-season level panel dataset that we construct using multiple sources- and the second is unit-record data from the NSS Employment Unemployment Surveys. To identify causal effects, we employ a difference-indifference matching (DIDM) procedure, where districts are matched based on propensity scores- the use of propensity scores represents a novel aspect of this paper. We also examine pre-programme trends for each outcome variable to provide a check on the validity of our estimates. Our results indicate modest changes in cropping patterns that are state- and period-specific- however they do not indicate any improvements in crop yields that were expected given the MGNREGA’s focus on investments in irrigation, although there is some evidence that irrigated area may have expanded after a lag. We also find that there is no systematic evidence of impact on wages, and therefore no evidence that public works employment in MGNREGA crowded out casual labour in agriculture. |

Abstract: | Many developed countries promote the use of biofuels for environmental concerns, leading to a rise in the price of agricultural commodities utilized in their production. Such environmental policies have major effects on the economy of emerging and developing countries whose activity is highly dependent on agricultural commodities involved in biofuel production. This paper tackles this issue by examining the price impact of biofuels on the current account for a panel of 16 developing and emerging countries, and the potential nonlinear effect exerted by the price of oil on this relationship. Relying on the estimation of panel smooth-transition regression models, we show that positive shocks in the price of biofuels lead to a current-account improvement for agricultural commodity exporters and producers only when the price of oil is below a certain threshold. When the price of oil exceeds this threshold, uctuations in the price of biofuels no longer affect the current account. These findings illustrate that a rise in the price of oil exerts a negative effect on the trade balance of commodity exporters which are also oil importers, dampening the biofuel price impact on the current-account position. |

Abstract: | Indonesia is a large country and most populous among members of ASEAN Economic Community (AEC). The purpose of this study is to perform a "mapping products" for agricultural commodity in Indonesia. This study utilizes data on export and import four-digit in the Standard International Trade Classification (SITC) Revision 2 from UN-COMTRADE for the period 1984-2014. We use Reveled Symmetric Comparative Advantage (RSCA) combined with Trade Balance Index (TBI) in our analysis. The primary result shows that dynamic changes in agricultural commodities have occurred in Indonesia. Agricultural commodities that perform de-specialization are rice, meat of sheep and goats (fresh, chilled, or frozen). On the other hand, agricultural commodities that experience specialization are fishery products. |

Abstract: | This paper investigates the issue of food security as the basis for stable economic development using the example of North Africa. A statistical analysis of economic and financial factors in relation to the determinants of food security was carried out using a panel cointegrating model based on official international statistics of the Food and Agriculture Organization (FAO) and the World Bank for 1991-2014. According to the results, population growth and the intensification of agricultural production, foreign trade and foreign direct investment play a crucial role in food security. The study revealed the relationship between food security and the development of the banking and financial systems in the region, and their degree of globalization. The strategy of a long-term investment policy pursued by the World Bank and FAO to combat hunger and poverty was justified. The methodology proposed can be used to monitor and evaluate the effectiveness of policies to maintain food security in the regions of Arfica. |

Abstract: | Because of low-frequency internal variability, the observed and underlying warming trends in temperature series can be markedly different. Important differences in the observed nonlinear trends in hemisheric temperature series would suggest that the northern and southern hemispheres have responded differently to the changes in the radiative forcing. Using recent econometric techniques, we can reconcile such differences and show that all sea and land temperatures share similar time series properties and a common underlying warming trend having a dominant anthropogenic origin. We also investigate the interhemispheric temperature asymmetry (ITA) and show that the differences in warming between hemispheres is in part driven by antropogenic forcing but that most of the observed rapid changes is likely due to natural variability. The attribution of changes in ITA is relevant since increases in the temperature contrast between hemispheres could potentially produce a shift in the Intertropical Convergence Zone and alter rainfall patterns. The existence of a current slowdown in the warming and its causes is also investigated. The results suggest that the slowdown is a common feature in global and hemispheric sea and land temperatures that can, at least partly, be attributed to changes in anthropogenic forcing. |

Abstract: | This paper offers an updated and extended attribution analysis based on recently published versions of temperature and forcing datasets. It shows that both temperature and radiative forcing variables can be best represented as trend stationary processes with structural changes occurring in the slope of their trend functions and that they share a common secular trend and common breaks, largely determined by the anthropogenic radiative forcing. The common nonlinear trend is isolated and further evidence on the possible causes of the current slowdown in warming is presented. Our analysis offers interesting results in relation to the recent literature. Changes in the anthropogenic forcings are directly responsible for the hiatus as in Estrada et al. (2013a), while natural factors such as the Atlantic Multidecadal Oscillation, the Interdecadal Pacific Oscillation and the Southern Annular Mode, as well as the new temperature adjustments in Karl et al. (2105) contribute to weaken the signal. In other words, natural variability and data adjustments do not explain in any way the hiatus, they simply mask its presence. |

Abstract: | Whether and how changes in economic circumstances or household income affect individuals’ diet and nutritional intakes is of substantial interest for policy purposes. This paper examines the extent to which, as well as how individuals protect their calorie intakes in the face of unanticipated shocks to household income. Our results suggest that households use substitution, disproportionally cutting back spending on non-foods to protect spending on foods, change the composition of the consumption basket, and increase the consumption of ‘cheaper’ calories. Taken together, we find that total nutritional intakes are almost fully protected against income shocks, with only very small changes in actual calorie intakes. Specifically, we find that 12-16% of the effect of permanent income shocks on food expenditures is transmitted to calorie intakes, with 84–88% protected through insurance mechanisms. |

Abstract: | This paper contributes to an emerging literature on the environmental Kuznets curve (EKC) relationship between pollution and income at the local level by analyzing emissions of carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOX), carbon monoxide (CO), particulate matter (PM2.5 and PM10) and total suspended particulate (TSP). We conduct several spatial statistical and econometric tests to account for spatial dependence between 290 Swedish municipalities on the selected emissions. Results highlight evidence that the pollution and income relationship is significantly characterized by spatial interaction effects. That is, municipality per capita emissions are strongly influenced by emissions trajectories in neighbouring municipalities. Implications of our findings on policy are discussed. |

Abstract: | With the onset of wide-ranging economic reforms in India in 1991, agents have been exposed to increased price risk in commodity markets. Futures markets are one important instrument for reducing price risk, and in this study we focus on the price discovery role of futures markets. Employing daily price data for nine crops for the period 2009-2014, we find strong causation running from futures to spot prices. Since spot prices impinge on the storage and cropping pattern decisions of farmers, our results imply that providing information on futures price to farmers on a daily basis would enable them to take more efficient decisions in the present. |

Abstract: | The authors explore the link between the systems approach to sustainability and the 17 Sustainable Development Goals (SDGs), which were formally adopted by the UN in 2015. The systems approach depicts sustainable development as the intersection of the goals attributed to three interlinked systems: environmental (or ecological), economic and social. The authors illustrate how each of the 17 SDGs can be characterized as a goal primarily attributed either to the environmental, economic or social system, and as suggested by the systems approach, there may be important tradeoffs in attempting to attain all these goals simultaneously. By adopting standard methods of the theory of choice and welfare under imposed quantities, the authors show that is possible to measure the welfare effects of an increase in the indicator level for one SDG by identifying the tradeoffs that occur with achieving another goal. They present a quantitative assessment of current progress and tradeoffs among the 17 SDGs, using a representative indicator for each goal. They then conduct a preliminary welfare analysis of these tradeoffs through employing the approach developed in this paper. Although this analysis focuses on the potential tradeoffs among SDGs, the approach could also be applied to show complementarities, or "winwins", in simultaneous progress among two or more SDGs. Such an analysis can help in the design of appropriate policy interventions to achieve specific SDGs, minimizing the potentially negative knock-on effects on some goals whilst capitalizing on the positive win-win impacts on other SDGs. |
