abstract protection policies in the agricultural sector is an inevitable necessity, its accomplish effects individuals welfare and economic sectors. protection policies account for a major economic strategy in agricultural sectors of developing and developed countries. applying ardl, the study investigates effects of protection policy in agricultural sector on total factor productivity of this ...

in present study, role of agricultural on eco countries regional convergence was assessed in dynamic panel data model. at first, eco countries convergence and agricultural sector effect in convergence acceleration was surveyed by generalized method of moments (gmm) over the period 1996-2005. results showed that, this is convergence between eco countries. in spite of increasing regional growth, ...

Donald A. Wilhite and Kenneth G. Hubbard Center for Agricultural Meteorology and Climatology University of Nebraska Lincoln, Nebraska The ability to collect weather data in near-real time has improved because of technological advances, enabling weather data users to obtain more weather data over wider areas, and in a more timely fashion. The number of near-real time climate networks is increasi...

This paper considers participatory modelling to integrate biodiversity conservation into land use planning and to facilitate the incorporation of ecological knowledge into public decision making for spatial planning. Réunion Island has experienced rapid urban and agricultural expansion, which threaten its unique biodiversity. In this context, we designed three participatory modelling sequences,...

Introduction Biomass energy has received much attention in recent years. We now use about one third of the U.S. corn crop for biofuels. More recently, attention has focused on cellulosic resources—dedicated energy crops like switchgrass, miscanthus, and corn stover. Now the question has been raised concerning the economics of collecting just the corn cobs for energy instead of the stover. This ...

The future of biodiversity and ecosystem services hinges on harmonizing agricultural production and conservation, yet there is no planning algorithm for predicting the efficacy of conservation investments in farmland. We present a conservation planning framework for countryside (working agricultural landscapes) that calculates the production and conservation benefits to the current baseline of ...

This study examined the training needs of agricultural extension agents in Delta State, Nigeria. A sample of 102 respondents was drawn from extension agents in the States’ Agricultural Development Programme (ADP), Ministry of Agriculture and Natural Resources (MANR) and the FADAMA Programme. Data were collected in February 2017 by using a structured and validated questionnaire. Data generated w...

The farmer requires detailed information on crop stress conditions in order to manage the crop growth. This information may be acquired by low granular satellite images to coarsely identify areas of interest within the field followed by ground measurements carried out by robotic surveying platforms for plant identification and segmentation. A novel concept for creating rational behaviors of sur...
