Targeting of agricultural conservation practices to the most effective locations in a watershed can promote wise use of conservation funds to protect surface waters from agricultural nonpoint source pollution. A spatial optimization procedure using the Soil and Water Assessment Tool was used to target six widely used conservation practices, namely no-tillage, cereal rye cover crops (CC), filter...

This paper presents scenario-based modelling of urban land use which stem from interactions of the urban functions of Sakarya, one of the most important city for agricultural production and a vulnerable region in terms of natural resources and seismicity in Turkey. The purpose of the paper is to estimate the future land use pattern of Sakarya and discuss the environmental effects of alternative...

Agricultural residues are the largest potential near term source of biomass for bioenergy production. Sustainable use of agricultural residues for bioenergy production requires consideration of the important role that residues play in maintaining soil health and productivity. Innovation equipment designs for residue harvesting systems can help economically collect agricultural residues while mi...

Agricultural expansion is one of the prime driving forces of global land cover change. Despite the increasing attention to the factors that cause it, the patterns and processes associated with indigenous cultivation systems are not well understood. This study analyzes agricultural change associated with subsistence-based indigenous production systems in the lower Pastaza River Basin in the Ecua...

ESEE 2015, Chania, GreeceConference dates: July 4 – 7, 2017Conference Theme: Transformative learning: new directions in agricultural extension and educationThe 23rd European Seminar on Extension (and) Education (ESEE) will be held in the MediterraneanAgronomic Institute of Chania, and hosted by the Lab. of Agricultural Extension, Rural Systems &Rural Sociology, Dept. of Agricultural Economics &...

An integrated optimization model was developed for the spatial distribution of agricultural crops in order to efficiently utilize agricultural water and land resources simultaneously. The model is based on the spatial distribution of crop suitability, spatial distribution of population density, and agricultural land use data. Multi-source remote sensing data are combined with constraints of opt...

The interaction between landuse change, nitrogen deposition, water recharge and carbon sequestration was investigated in the EU 5th Framework Programme project called AFFOREST. An important aspect of the project was the development of the AFFOREST spatial Decision Support System, designed to look at these issues simultaneously. The development of the nitrogen deposition module is described in t...

Agricultural drought is the leading cause for crop failure throughout the world. In the USA, significant impacts of recent droughts on agricultural production indicate the continuing vulnerability of the country to drought. This paper presents a methodology for spatial representation of the agroclimatic component of agricultural drought vulnerability. This methodology was developed as a part of...
