Renewable Energy Integration for Steam Supply of Industrial Processes—A Food Processing Case Study
(2020-05-16)
This study highlights the CO2,e -emission reduction potentials and related economic consequences for changing steam generation from fossil to renewable. Seven different utility concepts are developed, including a steam accumulator for load management. Peculiarities for the integration of biogas boilers, biomass-fuelled boilers, electrode steam boilers, biomethane-fuelled solid oxide fuel cells, micro gas turbine, solar energy systems, heat pumps and steam accumulators into a steam system with fluctuating steam demand ...

Soil–climate contribution to DNDC model uncertainty in simulating biomass accumulation under urban vegetable production on a Petroplinthic Cambisol in Tamale, Ghana
(2020-03-24)
Crop yield simulation using the Denitrification–Decomposition (DNDC) model can help to understand key bottlenecks for improved nitrogen (N) use efficiency and estimate greenhouse gas (GHG) emissions in West African urban vegetable production. The DNDC model was successfully calibrated using high‐resolution weather records, information on management practices and soils, and measured biomass accumulation and N uptake by amaranth (Amaranthus L.), jute mallow (Corchorus olitorius L.), lettuce (Lactuca sativa L.), and ...

Vehicular Livestock Mobility in West Africa: Seasonal Traffic Flows of Cattle, Sheep, and Goats across Bamako
(2020-12-26)
Mali is a major livestock producing country in West Africa. However, in recent years, the sector has faced multiple challenges like farmer-herder conflicts, overuse of grazing and water resources, and the effects of climate change. Meanwhile, traditional livestock systems are becoming less important given the increased availability of vehicular transport for regional and international animal trade as well as new opportunities for more specialised urban and peri-urban production systems. To assess the role of Mali’s ...

Determining Relationships between Marbling Scores and Carcass Yield Traits of German Beef Bull Carcasses Using Video-Image Analysis at the 12th and 10th Rib Position of Longissimus Thoracis and EUROP Classification
(2020-12-30)
In contrast to other international beef classification systems, the European EUROP system disregards marbling in meat quality assessment. Instead, it focuses primarily on the assessment of conformation and fat score. Due to the lack of more specific assessment, beef quality in Germany is less known than beef produced in other countries and is largely incomparable to international standards. The aim of this study was to explore the potential of video-image analysis (VIA) for the assessment of bull carcasses for the ...

Exploring land-use histories of tree-crop landscapes: a cross-site comparison in the Mediterranean Basin
(2020-05-02)
Agroforestry landscapes in the Mediterranean Basin have emerged in a co-evolution between humans and nature and provide numerous ecosystem services to society. Tree crops are iconic elements of these landscapes and have frequently been managed in a sustainable way over centuries, shaping multifunctional landscapes and local people’s cultural identities. However, many Mediterranean tree-crop landscapes are undergoing substantial land-use changes, threatening important ecosystem services as a result. The overarching ...

Bottoms up: Delivering sustainable value in the base of the pyramid
(2020-01-24)
Despite a wealth of expertise involving leading institutions over at least 15 years, a base of the pyramid (BoP) model resulting in scalability has yet to emerge. We posit that institutional gaps between BoP goals of developing human and social capital on one hand and a short‐term profit focus of business on the other contribute to the lack of scalability. We address this gap by proposing a social intermediary to link the BoP with firms involved in the BoP. The social intermediary will coordinate and interpret the ...

Effect of Sieve Particle Size and Blend Proportion on the Quality Properties of Peeled and Unpeeled Orange Fleshed Sweet Potato Composite Flours
(2020-06-04)
Orange fleshed sweet potato (OFSP) has great potentials to improve the nutritional benefits of bakery products when processed into quality flour. This study investigated the effects of sieve particle sizes (250 μm and 500 μm) and flour blend proportions on the physicochemical, nutritional, functional and pasting properties of peeled and unpeeled OFSP composite flours. Peeled OFSP composite flours had significantly (p < 0.05) higher crude protein (CP), lightness (L*), oil absorption capacity (OAC) and water solubility ...

Agricultural Development and Land Use Change in India: A Scenario Analysis of Trade‐Offs Between UN Sustainable Development Goals (SDGs)
(2020-01-15)
India has the second largest population in the world and is characterized by a broad diversity in climate, topography, flora, fauna, land use, and socioeconomic conditions. To help ensure food security in the future, agricultural systems will have to respond to global change drivers such as population growth, changing dietary habits, and climate change. However, alterations of how food is produced in the future may conflict with other UN Sustainable Development Goals (SDGs), such as the protection of land resources ...

Improving Animal Health on Organic Dairy Farms: Stakeholder Views on Policy Options
(2020-04-09)
Although ensuring good animal health is a stated aim of organic livestock farming and an important reason why consumers purchase organic products, the health states actually achieved are comparable to those in conventional farming. Unfortunately, there have been no studies to date that have assessed stakeholder views on different policy options for improving animal health on organic dairy farms. To address this deficit, stakeholder consultations were conducted in four European countries, involving 39 supply-chain ...

Establishing a Sustainable Waste Management System in a Transitional Economic Context: Analysis of the Socio-Economic Dynamics
(2020-05-09)
Establishing a sustainable waste management system concerns multiple aspects of the prospected geo-locations. Among them, the dynamics of the socio-economy play a crucial role. Based on the idea of circular economy (CE), the amount of waste, in general, should be reduced and the process of social involvement is embedded. This study aims to examine the social willingness towards a sustainable waste management system at a local level in Georgia. The research study was conducted with waste management analyses in Marneuli ...
