Agricultural Production and Yield Estimation: Two distinctive aspects of Brazilian Agriculture and a perspective on world food problems
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2013-12-20)
Brazil has been increasing its importance in agricultural markets. The reasons are well known to be the relative abundance of land, the increasing technology used in crops, and the development of the agribusiness sector which allow for a fast response to price stimuli. The elasticity of acreage response to increases in expected return is estimated for Soybeans in a dynamic (long term) error correction model. Regarding yield patterns, a large variation in the yearly rates of growth in yield is observed, climate being ...

Biofuel as the solution of alternative energy production?
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2013-04-23)
There have being increasing debate on the prospects of biofuel becoming the next best alternative to solving the problem of CO2 emission and the escalating fuel prices, but the question is whether this assertion is true and also if it comes without any cost to pay. This paper seeks to find out whether this much praised alternative to solving these problems is a better option or another way for the developed countries to find more areas where they could get cheap land, labour and raw materials for the production of ...

Improvement of Food Security in Bangladesh through Socio-Economic Empowerment of Women
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2013-04-01)
Empowerment is one possible approach to increase political, social and economic participation of a target group and thus decrease food insecurity among vulnerable people. The objective of this research was to evaluate a socio-economic empowerment project implemented for 8 years in rural northern Bangladesh by using secondary data from 2000 and primary data from 2009. Three hundred women were primarily selected out of all existing and active 121 women groups formed during 8 years project implementation. Standardized ...

Evaluation of water retention capacity and flood control function of the forest catchment
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2013-01-04)
This research quantitatively evaluates the water retention capacity and flood control function of the forest catchments by using hydrological data of the large flood events which happened after the serious droughts. The objective sites are the Oodo Dam and the Sameura Dam catchments in Japan. The kinematic wave model, which considers saturated and unsaturated sub-surface soil zones, is used for the rainfall-runoff analysis. The result shows that possible storage volume of the Oodo Dam catchment is 162.26 MCM in 2005, ...

Linking sustainable diets to the concept of food system sustainability
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Based on insights from an ongoing research project on food sustainability, we argue that discussing sustainable diets in isolation from food systems poses risks. Among these risks are making healthy diets exclusive, or ignoring externalities like biodiversity loss, land concentration, and encroachment on commons. Case studies from Bolivia and Kenya show how marked shifts from traditional to more uniform diets rich in sugar, salt, and fatty acids come with a radical transformation of food systems. Systems formerly ...

Palm oil supply and demand characteristics and behavior: A system dynamics approach
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Like other commodities, palm oil is characterized by common commodity cycles in the market. However, in this study, we argue that the palm oil market has distinctive traits compared to other commodity markets with regard to the cobweb theorem by elaborating on the characteristics of the Malaysian palm oil market and its basic underlying behavior. In an attempt to understand the behavior of the industry, researchers had been changing the paradigm of modelling the palm oil market by using the operationally-based modelling ...

Use of aquagel-Polymer as a soil conditioner for celery plants grown in sand culture
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Celery plants were grown in ten liter black plastic containers filled with sand substrate then mixed with three levels of aqua gel-polymer. Three levels of irrigation water were applied by using drip irrigation for each aquagel-polymer treatment. The experiment was carried out at the Protected Cultivation Experimental Farm in Dokki, Giza, Egypt to determine celery growth and yield under different studied treatments. Various levels of aquagel-polymer as well as irrigation water levels were applied in a factorial design ...

Seaweed farming as a sustainable livelihood option for northern coastal communities in Sri Lanka
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Sri Lanka has recently contributed to the growing significance of seaweed farming in the globe. This study attempted to assess the financial feasibility, employment generation, perceived importance, social acceptability and major constraints associated with seaweed farming in the Northern part of Sri Lanka. The study sample included 160 seaweed farmers from the area. A questionnaire survey, in-depth interviews and focus group discussions were conducted to collect data and information. Descriptive analytical, investment ...

Pollination of Acacia woodlands and honey production by honey bees in Kitui, Kenya
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Acacia woodlands dominate arid and semi-arid areas across the world and are an important source of livelihood supporting activities. This is also the case in Kenya, where the Acacia woodlands are under pressure, partly due to the extractive activities that generate household income, such as collection of fuelwood, building poles, charcoal burning and livestock fodder. There is an apparent dilemma between the extractive and non-extractive use of the Acacia woodlands, and a need to develop income generating activities ...

Vertical price linkages in food markets: Evidence from the tomato value chain of Northern South Africa
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Price transmission in agricultural fresh produce markets is a subject of considerable interest to policymakers given that improved market performance for agricultural commodities promotes market development and maximization of social welfare. In northern South Africa, where tomato production dominates the country, studies exist on the general production, marketing, and consumption of fresh produce. However, the literature lacks an analytical component that is pertinent to the mechanism of price transmission and ...
