Global footprints of water and land resources through China's food trade Полный текст
2017
Ali, Tariq | Huang, Jikun | Wang, Jinxia | Xie, Wei
China's rapid increase in food imports has repercussions for China's and global resources. This study reviews the recent literature on China's virtual water and land trade through food trade, presents updated results for 2000–2015, and makes projections for 2030. The results show that the increased imports of virtual water and land have significantly eased pressure on these resources in China. Soybean imports have been the main contributor towards China's domestic savings of virtual water and land. China's food trade has increasingly contributed towards global savings of virtual water and land. Our projections suggest that the trend in savings of domestic and global virtual water and land will continue, with significant variations due to changes in resource use efficiency.

The purpose of the study is to assess whether Corporate Social Responsibility regarding water is considered relevant for sustainability in companies related to agriculture in South Africa, considering that their impact directly influences public access to water. To accomplish this purpose, a qualitative approach was developed through the study of the 22 existing companies from the agriculture sector, food and beverages, forest and paper production, and Tobacco, which published their last integrated report within the Global Reporting Initiative framework. A thematic content analysis was carried out, involving the analysis of the written sustainability reports. For data analyses, ATLAS.ti 7.1 software was used to match the main aspects related to water management. Pragmatic advice for practitioners derives from the research results, considering that Corporate Social Responsibility in general—and sustainable water management in particular—represents an opportunity for companies to get competitive advantages in the market. The study also determines the best practices in the field in South Africa with benchmarking purposes.

[Departement_IRSTEA]Ecotechnologies [TR1_IRSTEA]SPEE | To reduce the proliferation of bacteria inside food plants, cleaning and disinfection are performed daily following production. These operations are followed by drying during which the drying rate should be as high as possible. This study shows the influence of a dehumidifier on the water mass evolution on surfaces during the drying of a food plant. The temperature, relative humidity and water mass evolution were monitored under two conditions: with and without a dehumidifier. Comparison of the results shows that the drying rate is about 1.5 times higher when a dehumidifier is used. These data were used to develop a simplified heat and mass transfer model allowing the prediction of the temperature and drying rate at different locations. The results can help the manufacturer to evaluate the benefits of a dehumidifier and consider the use of other devices to achieve better airflow distribution or greater heat supply for certain surfaces.

Modern bioenergy is a core ingredient of sustainable economic development as it plays an important rolein poverty reduction and green growth. This makes bioenergy innovations critical, especially in developingcountries where many households and rural communities rely on traditional bioenergy. Managing themultiple tradeoffs among bioenergy use, agricultural productivity, and ecosystem functions is a majordevelopment challenge. Addressing this challenge requires the identification of the drivers, tradeoffs andimpacts of bioenergy production, trade and use in the Water, Energy and Food Security Nexus. The keyobjective of this paper is to provide an analytical framework and assess the track record of policy actions tostimulate modern bioenergy innovation in order to achieve multiple-win outcomes in terms of povertyalleviation, improved health and gender empowerment and environmental sustainability. We begin bydescribing the global trends and drivers in bioenergy production, trade and use. Secondly, we review thestate of the art on impacts and links of bioenergy with the other Nexus components. Thirdly, we suggest aconceptual framework for evaluating the synergies and tradeoffs of bioenergy with other bioeconomic andeconomic activities along the Nexus. Follow-up empirical research at household and community levels inseveral developing countries will be based on this framework. Finally, a discussion on the conceptualframework is enriched by insights on the relevant actors, the tools and mechanisms specific to these actorsfor catalyzing innovations in the bioenergy for development.

The Land–Water–Food Nexus: Expanding the Social–Ecological System Framework to Link Land and Water Governance Полный текст

Frederike Klümper | Insa Theesfeld
To date, the land–water–food nexus has been primarily addressed from an ecological, hydrological or agronomic angle, with limited response to the governance interface between the input resources. Likewise, in widely used heuristic frameworks, such as the social–ecological system (SES) framework, governance interactions between resources are not sufficiently addressed. We address this gap empirically, using the case of Tajikistan, based on a farm household survey analysis of 306 farmers. The results indicate that land system variables contribute to the willingness to cooperate in irrigation management. Specifically, formal land tenure has a positive effect on farmers paying for water as well as on the likelihood of their investing time and effort in irrigation infrastructure, which is decisive for Tajikistan’s food and fiber production. Irrigation system variables show that, e.g., being an upstream user increases the likelihood to contribute to labor maintenance efforts. We further discuss how decisions with respect to the land sector could be designed in the future to facilitate cooperation in other resource sectors. Further, we conclude from a conceptual perspective that the SES framework integrating a nexus perspective can be adapted: either (1) by adding a second-tier “governance nexus” variable inside the governance variable of an irrigation system: or (2) by adding a land resource unit and system outside the irrigation system.
