Many livestock sector models have limited coverage of relevant variables, and are somewhat ad hoc in their choice of what should be specified as behavioral equations. This study develops a generic conceptual approach to modeling the livestock sector that provides consistent rules of specification and better coverage of variables. This approach is then applied to the swine-pork sector of Japan. ...

The aim of this research is to analize impact pandemic covid 19 food crop sub-sector at Jambi Province. This was using descriptive metodology. Using time series data from 2019 until 2020. selection locations in study purpossive with the consideration that Province has great potential producing crops., results showed Covid-19 did not have a direct on exchange rate farmers but had an development ...

in order to decrease water consumption in agricultural sector, deficit irrigation has been suggested. for preventing a heavy loss in crop yield, management of water stress is essential. common methods for measuring plant water stress such as stomatal conductance are time-consuming and require specialized labor and a large number of measurement. temperature of leaf or canopy surface can be an in...

The global environmental change research community requires improved and up-to-date land use/land cover (LULC) datasets at regional to global scales to support a variety of science and policy applications. Considerable strides have been made to improve large-area LULC datasets, but little emphasis has been placed on thematically detailed crop mapping, despite the considerable influence of manag...

We present the initial setup of the Lofar Agro project that concentrates on monitoring micro-climates in a crop field. In addition to the agronomic experiment, Lofar Agro aims at gathering statistics on the wireless sensor network itself. These statistics will form the basis for simulations of algorithms in wireless sensor networks and will be distributed. 1. PRECISION AGRICULTURE In the past f...

A mechanistic model of N2O emission from agricultural soil (DeNitrification-DeCompositionFDNDC) was modified for application to the UK, and was used as the basis of an inventory of N2O emission from UK agriculture in 1990. UK-specific input data were added to DNDC’s database and the ability to simulate daily C and N inputs from grazing animals and applied animal waste was added to the model. Th...

Current agriculture faces the challenge of doubling food production to meet the food needs of a population expected to reach 9 billion by mid-century whilst maintaining soil and water quality and conserving biodiversity. These challenges are more overwhelming for the rural poor, who are the custodians of environmental resources and at the same time particularly vulnerable to environmental degra...
