Although not conspicuous in its literature, agricultural modelling and its applications have inherited much from the field of operational (operations) research. In the late 1940s, techniques for mathematically simulating processes came into agricultural science directly from industry. The decision support system (DSS) concept followed almost 40 years later. It seems that the large differences b...

Despite the routine collection of annual agricultural surveys and significant advances in GIS and remote sensing products, little econometric research has integrated these data sources in estimating developing nations' agricultural yields. In this paper, we explore the determinants of wheat output per hectare in Ethiopia during the 2011-2013 principal Meher crop seasons at the kebele administra...

Complex ecological issues like depredation and its management are determined by multiple factors acting at more than one scale and are interlinked with complex human social and economic behaviour. Depredation by wild herbivores can be a major obstacle to agricultural community support for wildlife conservation. For three decades, crop and fence damage, competition with livestock for native rang...

Much of the world’s gene pool is located in tropical rainforests, which are being destroyed at an alarming rate. Proper management of protected forests is crucial to avoid further loss of biodiversity. Resource extraction by local communities can be a major obstacle in the management of protected forests. This paper develops a two sector dynamic model for agriculture and forest resource extract...

Increasing competition for water across sectors increases the importance of the river basin as the appropriate unit of analysis to address the challenges facing water resources management; and modeling at this scale can provide essential information for policymakers in their resource allocation decisions. This paper introduces an integrated economic–hydrologic modeling framework that accounts f...

This study investigated differences in learning styles and personality types among engineering students, agricultural systems management students, and faculty in the Department of Agricultural and Biological Engineering at Pennsylvania State University. Learning styles and personality types were evaluated using the Group Embedded Figures Test (GEFT) and Myers-Briggs Type Indicator (MBTI), respe...

The status of damage by vertebrate pests to growing and stored agricultural crops is reviewed in the light of changing patterns of agricultural practice and land use within the UK. Significant problems and existing management techniques are briefly discussed. The results of recent research by the Agricultural Department and Advisory Service (ADAS) of the Ministry of Agriculture, Fisheries and F...

As we know, the decentralized management of agricultural production is inconsistent with the big market and circulation in our country. Facing this situation, we suggest strong enterprise construct third party agricultural public trade platform under the guide of the government in a way of market-based operation. The drive to build such platform from government, enterprises, peasant and agricul...
