Abstract The optimal management of scarce transboundary water resources among competitive users is expected to be challenged by the effects climate change on availability. multiple economic and social implications, including conflicts between neighbouring countries, as well sectors within each country are difficult estimate predict, inform policy-making. In this paper, problem approached a stoc...

INTRODUCTION Biotechnology with its promise to revolutionize agriculture around the world is assuming an increasingly greater role in India’s agricultural research. The indiscriminate use of chemical pesticides has affected humans and their environment and insect pests remains to be one of the major limiting factors in sustaining the productivity of various crops. The concept of IPM for sustain...

The USDA rice core collection, containing 1,801 accessions from 115 countries or sources and representing about 10% of the whole collection, was established by a stratified random-sampling method. A total of 990 accessions in the core collection that headed in 110 days or less and were 150 cm or less in height were evaluated for straighthead resistance on a 1 to 9 scale with 1 being very resist...

Using data collected from 400 farming households in the Casamance area of Senegal, the paper demonstrates that not only farm and farmers' characteristics, but also farmers' perceptions of technology-speci®c characteristics, signi®cantly in ̄uence adoption decisions relating to improved rice varieties. Farmers' perceptions about improved rice varieties were quanti®ed using a quasi-arbitrary ordin...

The present work estimated the genetic variability and relatedness index of the fifth stock of Pacific white shrimp, Litopenaeus vannamei, imported into Cuba for farming purposes from the US Shrimp Improvement System (SIS). Genetic variability was estimated by genotyping 33 samples for four microsatellite loci: M1, Pvan 1815, Pvan 0040 and Pvan 1758. This stock had average expected and observed...

Effective maintenance of crop diversity within farming systems has been the subject of many studies over the last decade. Although the benefits of agrobiodiversity have been widely recognised and encouraged through global conservation and policy awareness initiatives, its use is constrained due to the limited number plant breeders who can respond to all the needs of the poor farmers. Agrobiodiv...

Brazil is one of the most biodiversity rich countries in the world, including a wealth of agricultural biodiversity in both wild and cultivated forms. This is particularly noticeable in southern Brazil, home to a wide array of underutilized food species whose genetic diversity is maintained mostly by farmers through on-farm management practices. Farmers’ contribution in safeguarding and keeping...

Role of expert systems in agriculture and its applications in efficient crop production and protection technologies has been reviewed and discussed in this paper. Different domains of agriculture are highlighted where expert systems can play an important role for an expert in transferring expert-driven knowledge instantly at the level of farmer‟s field. This paper explores structure of an exper...

Global market economy and the growing concern about environment have been moving agricultural production into the area of conflict between economy and ecology. Increased efficiency in agricultural productivity via plant breeding, mechanization, and management techniques have all been important factors in maintaining the balance between food supply and world demand. Necessary improvements in the...

The Czech University of Life Sciences Farm at Lany began farming common eland with the aim of achieving full economic self-sufficiency through animal production for breeding and meat. Alternative goals were to verify production technology for farming common eland in captivity and the utilization of this species as an alternative for meat production in mild climatic zones. The model farm was pri...
