The Impact

The diffusion of the technological innovation can affect the agricultural sector in the three-sided (social, economic and environmental), a hand, it can contribute to solve problems of the agricultural sector: the effects of the climatic changes, the farming exodus and the migration and the problems of poverty and it can improve the agricultural productivity. But on the other hand, he can lead to new problems, such as depletion of energy resources caused by excessive use of energizing technologies, pollution of air and water and the destruction of soil by industrial waste. This paper aims to theoretically and empirically analyze the role of technological innovation in improving agricultural sustainability through the impact of mechanization on agricultural productivity, energy production and net income per capita for a panel of three Maghreb countries (Algeria, Morocco and Tunisia) during the period 1997-2012. By using simultaneous equations, the authors' finding that technological innovation cannot achieve the purpose of sustainable development in the agriculture sector in the Maghreb countries through the negative impact of mechanization and research and development on agricultural productivity.

AbstractMulti-stakeholder initiatives (MSIs) have emerged as a leading institutional approach for advancing sustainability globally. This paper examines three prominent MSIs that have developed sustainability metrics and a standard for US agriculture: Field to Market, the Stewardship Index for Specialty Crops and the National Sustainable Agricultural Standard Initiative. Using data from interviews and content analysis of initiative reports, two sets of analyses are presented. First, building on Paul Thompson's tri-partite theorization of sustainability, how each initiative is conceptualizing agricultural sustainability is analyzed. We find that two contrasting visions of sustainable agriculture for the USA have emerged from the three MSIs. One vision is a resource sufficiency approach focused on eco-efficiencies and the other vision is a functional integrity approach that emphasizes the maintenance of resilient agricultural and ecological systems. Second, we examine the governance practices of the MSIs to explain why such divergent conceptualizations of sustainability have been mapped out. We find that far from being a neutral forum, the internal dynamics of MSIs often reflect and reproduce existing power relationships among stakeholders. In concluding, we suggest that incremental improvements in sustainability can be achieved using MSIs, but more transformative changes may require other forms of governance.

PurposeThis paper seeks to identify the prevailing streams in the research of climate-smart agriculture in order to help to conceptualize this new scientific notion and assist in drawing clear borders between climate-smart agriculture, agricultural sustainability and resilience.Design/methodology/approachIn order to conceptualize the climate-smart agriculture (CSA), the current research provides an in-depth bibliometric analysis indicating the prospective research directions in CSA. The findings of this paper are important in guiding the research on creation of climate-smart agriculture across different regions.FindingsThe notion of the CSA covers three main objectives: increased productivity, enhanced resilience and reduced environmental footprint of agriculture. It is found that due to its novelty, the climate-smart notion does not always have its defined research agenda and is considered to be both a constituent part of some other scientific framework (e.g. sustainability) and an independent research avenue.Originality/valueThis paper presents an in-depth analysis of the literature on the CSA. The linkages among the concepts, research centers and research strands are identified via the citation-based analysis.

Cereal Yields

Because environmentally degrading inorganic fertilizer use underlies current worldwide cereal yields, future agricultural sustainability demands enhanced nitrogen use efficiency. We found that genome-wide promotion of histone H3 lysine 27 trimethylation (H3K27me3) enables nitrogen-induced stimulation of rice tillering: APETALA2-domain transcription factor NGR5 (NITROGEN-MEDIATED TILLER GROWTH RESPONSE 5) facilitates nitrogen-dependent recruitment of polycomb repressive complex 2 to repress branching-inhibitory genes via H3K27me3 modification. NGR5 is a target of gibberellin receptor GIBBERELLIN INSENSITIVE DWARF1 (GID1)–promoted proteasomal destruction. DELLA proteins (characterized by the presence of a conserved aspartate-glutamate-leucine-leucine-alanine motif) competitively inhibit the GID1-NGR5 interaction and explain increased tillering of green revolution varieties. Increased NGR5 activity consequently uncouples tillering from nitrogen regulation, boosting rice yield at low nitrogen fertilization levels. NGR5 thus enables enhanced nitrogen use efficiency for improved future agricultural sustainability and food security.
