Despite the resurgence of parastatal marketing boards and strategic grain reserves over the last decade in eastern and southern Africa, there is little empirical evidence about how their activities affect smallholder input use and cropping decisions. This paper uses panel survey data from 1997-2007 on Kenyan smallholders to investigate the effect of Kenya’s National Cereal Produce Board activit...
Climate is changing and, as a consequence, some areas that are climatically suitable for date palm (Phoenix dactylifera L.) cultivation at the present time will become unsuitable in the future. In contrast, some areas that are unsuitable under the current climate will become suitable in the future. Consequently, countries that are dependent on date fruit export will experience economic decline,...
Since independence, different institutional arrangements have been tried to reorganize the land and production relations for bringing change in farming systems and enhancing crop yield of small farmers. But, these interventions have not been successful in bringing any meaningful improvement. Non-viability of small landholdings, inadequacies in the availability of inputs, poor extension and infr...
The objectives of this paper are to present progress in crop growth modelling for decision support in the South African sugarcane industry, and to discuss possible directions towards better exploitation of the tools developed at SASRI. It is shown that their dynamic nature and process orientation make simulation models particularly useful as a basis for decision support systems (DSS) in crop ma...
Shaping agriculture for both human needs and for environmental health can be greatly accelerated by properly developing the trait of apomixis. Apomixis is the phenomenon by which certain plants produce ‘seeds without sex’. Introduction of this trait to crop plants would allow the immediate fixing of the genetic make-up of any individual plant that responded particularly well to a given environm...
Crop production risk caused by climate variability cannot be managed in the absence of climate information. Despite the use of various communication strategies by rural communities in Tanzania, access and use of agricultural information is inadequate to cope with challenges in crop production. This study aims at assessing farmers information needs, examine communication strategies used and henc...
Natural rubber (NR), regarded as nature's most versatile raw material is obtained from the latex of Hevea brasiliensis, a tree, native to the tropical rain forests of Amazon and introduced on a commercial scale to the Far East during the last century. In India, organised cultivation of rubber started in 1902 on an estate scale by European planters. This crop however came out of the bounds of th...
Recent concentration of indoor livestock farming in the Highlands of the Reunion Island generates environmental risks. Livestock effluent management is often difficult due to the lack of suitable spreading areas close to the farms. However, crop farms in the Lowlands are demanding organic matter to maintain soil fertility. This is the case of the locality of Grand-Ilet where pig and poultry eff...
In the light of daunting global sustainability challenges such as climate change, biodiversity loss and food security, improving our understanding of the complex dynamics of the Earth system is crucial. However, large knowledge gaps related to the effects of land management persist, in particular those human-induced changes in terrestrial ecosystems that do not result in land-cover conversions....
this article aims at strategic vision to technology and suggests a strategic planning for this purpose. the main emphasis in this article is on strategic report compilation in the framework of strategic vision and covers issues such as identification of strategic planning dimensions and strategic vision levels, technology priority setting, environment monitoring, focus on costumer needs, method...
