Index-based insurance for climate risk management and rural development in Syria
International Center for Agricultural Research in the Dry Areas (ICARDA)
Abstract
Improving the adaptive capacity of rural producers to climate and weather risks may become an urgent issue in the early stages of political stabilization in Syria. Therefore, this study analyses the agro-ecological, economic and social benefits of â?? and the institutional challenges to â?? establishing index-based insurance markets to catalyse rural development in Syria.…

Two Novel DNAs That Enhance Symptoms and Overcome CMD2 Resistance to Cassava Mosaic Disease
International Institute of Tropical Agriculture (IITA)
Abstract
Cassava mosaic begomoviruses (CMBs) cause cassava mosaic disease (CMD) across Africa and the Indian subcontinent. Like all members of the geminivirus family, CMBs have small, circular single-stranded DNA genomes. We report here the discovery of two novel DNA sequences, designated SEGS-1 and SEGS-2 (for sequences enhancing geminivirus symptoms), that enhance symptoms and break…

The distribution of phosphorus fractions and desorption characteristics of some soils in the moist savanna zone of West Africa
International Institute of Tropical Agriculture (IITA)
Abstract
The fractionation of soil P into various organic and inorganic pools with differing levels of bioavailability, coupled with knowledge of the P adsorption and desorption characteristics of the soils, provides insights into management strategies that enhance P availability to crops. Sequential soil P fractionation was conducted on samples from 11…

AN ASSESSMENT OF INTEGRATED STRIGA HERMONTHICA CONTROL AND EARLY ADOPTION BY FARMERS IN NORTHERN NIGERIA
International Institute of Tropical Agriculture (IITA)
Abstract
Two sets of on-farm trials, each covering two years, were conducted in the northern Guinea savannah of Nigeria over the period 1999–2001, the objective being to compare integrated Striga hermonthica control measures (soybean or cowpea trap crops followed by maize resistant to Striga) with farmers' traditional cereal-based cropping systems. In both sets of trials…

On-farm research
International Institute of Tropical Agriculture (IITA)
Abstract
During 1984, intensive on-farm trials were conducted in northern, southern, and central Narino, Colombia, and emphasis was given to the continuation of var. trials and their expansion to determine economic levels and to verification trials. In northern and central Narino, a limited no. of verification trials were planted using the most promising components from 1982B. In both sets of trials, the new agronomic practices offered no yield advantage over…

Effects of land cover on ecosystem services in Tanzania: A spatial assessment of soil organic carbon
International Institute of Tropical Agriculture (IITA)
Abstract
The multiple ecosystem services provided by healthy soil are well known and include soil carbon sequestration to mitigate climate change, a medium for plant and agricultural production and regulating the hydrologic cycle. Despite the wide recognition of the importance of these services, drivers of soil organic carbon (SOC) dynamics across various land uses in East Africa…

Combining mineral fertilizer and green manure for increased, profitable cassava production
International Institute of Tropical Agriculture (IITA)
Abstract
Due to increasing population pressure and declining soil fertility, there is need for profitable alternatives to the slash-and-burn (SB) practice for cassava (Manihot esculenta Crantz) production in the humid lowlands of sub-Saharan Africa. Integrated Soil Fertility Management (ISFM) has high potential to deliver such options. Two on-farm, researcher-managed trials were installed…
