To evaluate changes to hop industry concentration and competitiveness the Herfindahl-Hirschman Index (HHI) was used. The ownership of proprietary varieties, their acreage production were compared with public varieties. Market share for each variety calculated between 2000 2020. quantity land under centralized control in U.S. due increased 2020 quantified. Assuming tacit collusion participants o...

The main objective of this study was to assess the impact of farmer field schools on adoption of technical packages of wheat production in Gezira Scheme, Sudan. Field survey was used to collect data from 50 FFS-participants of two schools (25 from each school), and also equal number from Non-FFS participants were selected for comparison. Close ended questionnaire was used in data collection. Th...

In line with sustainable agriculture that depends on modern methods and new sources of non-traditional irrigation, a field experiment was conducted at privet farm behind Cairo-Alexandria Desert Road, Giza, Egypt during two seasons to evaluate five sugar beet varieties under water salinity stress condition. The present work included 15 treatments; represent varieties: viz. Multi-germs (Amina, Fa...

In this article we investigate if qualitative soil fertility datasets derived during participatory processes can be combined with a corresponding land use change model (i) to improve the understanding of the socialecological complexity of land use change and (ii) to allow testing of alternative scenarios even in datapoor environments. To test this hypothesis, a participatory assessment approach...

Recent advances in ecological modeling have focused on novel methods for characterizing the environment that use presence-only data and machine-learning algorithms to predict the likelihood of species occurrence. These novel methods may have great potential for land suitability applications in the developing world where detailed land cover information is often unavailable or incomplete. This pa...

The Green Revolution, through the adoption of new crop varieties, irrigation, and agrochemicals, saved about 1 billion people from famine by increasing global food production (FAO 2011). We now recognize that these enormous gains in agricultural production were accompanied by harm to agriculture’s natural resource base, jeopardizing our future ability to meet human food, fuel, and fiber needs f...
