Personal communication as a strategy to improve the quality of household organic waste – Does it work? results from a quasi-experimental study in Northern Hesse, Germany
(2024-04-22)
Household organic waste has great potential for closing nutrient cycles in agriculture. This requires proper waste separation by households. Personal communication at the doorstep potentially improves household waste separation behaviour but it is expensive and findings from existing research are mixed. Based on results of previous studies and from a quasi-experiment with non-equivalent groups design in two German municipalities, this paper argues that efficiency of personal communication depends on its context. It ...

Yield stability of silage maize double cropping systems across nine German environments
(2023-10-19)
Introduction: Yield and its stability are both vital characteristics to evaluate the viability of cropping systems. However, the current frames of field research hardly allow an accurate evaluation of short-term effect stability. Therefore, over nine German environments (three years and three locations), first crop, maize, total harvested dry biomass yield (DMY), and maize dry matter content (DMC) variability were evaluated through a risk assessment in an organically managed silage maize experiment comprising 18 ...

Can carbon payments improve profitability of traditional conventional and organic cocoa agroforests? A case study in the Eastern Region of Ghana
(2023-03-16)
This study investigates the carbon (C) sequestration of traditional cocoa agroforestry systems in the Eastern Region of Ghana and the theoretical impact of CO₂ emission rights trading on their profitability. The study was conducted in four villages of Suhum Municipality, two each with either conventional or organic cocoa cultivation systems. Profitability was calculated using net present value of net cashflow (NPV), benefit cost ratio (BCR), and modified internal rate of return (MIRR). Carbon revenues were calculated ...

Blood in milk in horned dairy cows–Exploration of incidences and prevention opportunities
(2023-07-20)
Husbandry of horned cows is one alternative to disbudding that respects the animals´ integrity. Concurrently, housing and management should be aligned with the animals' needs to minimize social interactions that can result in integument damage (ID) and udder injuries associated with blood in milk (BM). No information is available on incidences of BM, nor on specific preventive measures. Thus, this study aimed at investigating BM incidences in horned herds and testing whether compliance with guideline recommendations ...

Prioritizing strategies for wheat biofortification: Inspiration from underutilized species
(2023-10-05)
The relationship between malnutrition and climate change is still poorly understood but a comprehensive knowledge of their interactions is needed to address the global public health agenda. Limited studies have been conducted to propose robust and economic-friendly strategies to augment the food basket with underutilized species and biofortify the staples for nutritional security. Sea-buckthorn is a known “superfood” rich in vitamin C and iron content. It is found naturally in northern hemispherical temperate Eurasia ...

Agrarian change through speculation: Rural elites as land brokers for mining in Colombia
(2023-08-31)
This paper studies the connections between the expansion of mining capital, speculative forms of land grabbing and agrarian transformation. It is argued that in periods of commodity boom, the landowning rural elite benefits from mining through speculative land deals with mining companies. They act as ‘land brokers’ for the mining firms, helping them to overcome a significant barrier to land accumulation through the de facto abolition of landed property. The analysis is based on a qualitative case study on the expansion ...

Comparative quality analysis and economic feasibility of solar assisted yogurt processing unit for decentralized dairy value chain
(2023-04-27)
Due to the lack of farm-gate milk processing facilities, dairy farmers have to sell raw milk, resulting in economic and quality compromises. The study compared the quality of yogurt processed in solar assisted yogurt processing unit with the existing milk value chain and its techno-economic feasibility. For this, an investigation of the experiment was executed where four different milk processing approaches were compared. The quality attributes for processed milk like fat (5.283%), solid-not-fat (9.0833%), salts ...

Biodistricts as a tool to revitalize rural territories and communities: insights from the biodistrict Cilento
(2023-11-03)
The necessity and urgency of the food systems transformation is no longer questionable, and the transformation pathways are inevitably reappearing as a subject of academic and public debate. In search of sustainable food production strategies as part of a broader transformation, organic food systems are called for as one of the solutions to achieve environmentally friendly and just food systems. In this context, the role of biodistricts has been recently emphasized at the EU level. The authors of the manuscript argue ...

Urbanisation threats to dairy cattle health: Insights from Greater Bengaluru, India
(2023-10-05)
Complex urbanisation dynamics, on the one hand, create a high demand for animal products, and on the other hand put enormous pressure on arable land with negative consequences for animal feed production. To explore the impact of accelerated urbanisation on dairy cattle health in urban farming systems, 151 farmers from different parts of the Greater Bengaluru metropolitan area in India were individually interviewed on aspects addressing cattle management and cattle health. In addition, 97 samples of forages from the ...

Narratives of land abandonment in a biocultural landscape of Spain
(2023-10-31)
Rural abandonment is a significant process in the Mediterranean region, posing sustainability challenges for rural and urban areas. Although there is an increase in studies focusing on the ecological implications and impacts of land abandonment and the role of rewilding, there is a knowledge gap in the study of the socio-cultural dimension of abandonment from the local perspective, even though it is crucial for land management decision. This study focuses on a case study in Western Spain, where a social survey was ...
