Soil and crop management under conservation agriculture in Zimbabwe
Carbon mitigation strategies and mechanisms have been globally implemented in an attempt to prevent catastrophic climate change. Kyoto targets require reductions in greenhouse gas emissions and increases in carbon sequestration. Although a number of carbon neutral technologies have been adopted such as bio-fuel and alternative energies, these currently fail to meet global requirements. An innov...
متن کاملWater Infiltration and Moisture in Soils under Conservation and Conventional Agriculture in Agro-Ecological Zone IIa, Zambia
Conservation agriculture is often presented as being ‘climate smart’ due to anticipated increases in soil moisture. The extent of enhanced water availability in farmers’ fields is, however, poorly documented. This paper presents five data sets describing soil moisture in fields of small-scale conservation and conventional farmers in the Agro-ecological Zone IIa, Zambia. The data include (1) soi...
متن کاملCrop production growth in different agro-ecological zones of Bangladesh
The purpose of this study is to evaluate the progress and regional variations of crop production in Bangladesh. The secondary data were used and collected for the years 1980-81 to 2002-03 from the ‘Statistical Yearbooks of Bangladesh’, ‘Yearbook of Agricultural Statistics’ and population census of different years. The study was conducted during the period from September 2006 to February 2008. A...
متن کاملCrop Residues Management with Conservation Agriculture: Potential, Constraints and Policy Needs
Suggested citation IARI (2012) Crop residues management with conservation agriculture: Potential, constraints and policy needs. Indian Foreword India being an agriculture-dominant country produces more than 500 million tons of crop residues annually. These residues are used as animal feed, for thatching of homes, and as a source of domestic and industrial fuel. A large portion of unused crop re...
متن کاملCrop pathogen emergence and evolution in agro-ecological landscapes
Remnant areas hosting natural vegetation in agricultural landscapes can impact the disease epidemiology and evolutionary dynamics of crop pathogens. However, the potential consequences for crop diseases of the composition, the spatial configuration and the persistence time of the agro-ecological interface - the area where crops and remnant vegetation are in contact - have been poorly studied. H...
