The first epidemic of cotton leaf curl disease (CLCuD) in early 1990’s in the Indian subcontinent was associated with several distinct begomoviruses along with a disease-specific betasatellite. Resistant cotton varieties were introduced in late 1990’s but soon resistance was broken and was associated with a single recombinant begomovirus named Burewala strain of Cotton leaf curl Kokhran virus that lacks a full complement of a gene encoding a transcription activator protein (TrAP). In order to understand the ongoing changes in CLCuD complex in Pakistan, CLCuD affected plants from cotton fields at Vehari were collected. Illumina sequencing was used to assess the diversity of CLCuD complex. At least three distinct begomoviruses characterized from the first epidemic; Cotton leaf curl Multan virus, Cotton leaf curl Kokhran virus and Cotton leaf curl Alabad virus, several distinct species of alphasatellites and cotton leaf curl Multan betasatellite were found associated with CLCuD. These viruses were also cloned and sequenced through Sanger sequencing to confirm the identity of the begomoviruses and that all clones possessed a full complement of the TrAP gene. A new strain of betasatellite was identified here and named CLCuMuBVeh. The implications of these findings in efforts to control CLCuD are discussed.

“…Importantly, agricultural system innovation in high risk or fragile natural environments requires careful institutional management of informal and formal knowledge systems (Brooks and Loevinsohn 2011), particularly in the context of the smallholder farmers operating in developing areas (Foley et al 2011;Anthony and Ferroni 2012). Many studies have identified the potential for smallholder agro-ecological approaches to promote social and ecological sustainability in different developing area settings (Pinstrup-Andersen and Hazell 1985;Pinstrup-Andersen et al 1999;Conway 1987;Pinstrup-Andersen and Herforth 2008); however, their potential to innovate is often undermined by limited access to resources, low levels of technology adoption, difficulties in coordination, asymmetries in information flow, and high levels of exposure to external and internal shocks Kydd and Dorward 2004;Birner and Resnick 2010).…”

Exploring the role of social capital in influencing knowledge flows and innovation in smallholder farming communities in the Caribbean

This paper presents the results of an exploratory study into how different forms of social capital embedded within community-based social networks may affect innovation in smallholder farming systems to better support food security in the Caribbean. Focusing on two rural communities in the small island developing nation of Saint Lucia, our results indicate the strong presence of interpersonal agricultural knowledge networks operating to: 1) facilitate farmer-tofarmer knowledge exchange; 2) increase farmer access to information; and 3) connect farmers to sources of support. In both communities, 'peer farmers' were reported as being the primary source of new agricultural knowledge for farmers, with government 'extension officers' the secondary source. Comparative social network analysis reveals how different forms of social capital within the two agricultural knowledge networks can affect self-reported farmer innovation in different contexts. Based on these findings we identify a number of opportunities for policy initiatives to better support, coordinate and enhance innovation opportunities among smallholder farmers in the Caribbean with a view to building their adaptive capacity in the face of environmental change. The findings provide important evidence and insights relevant to the governance of domestic agricultural systems and regional food security programming in the Caribbean.

“…The first one relates to the amount of funding and investment that influence research capacity and the ability to develop enhanced traits and varieties genetics (Anthony and Ferroni, 2011;Adenle, 2014). A second class of factors results from the lack of foreseeable regulatory structures, as a result of high development costs (Bayer et al, 2010), accountability risks and insufficient supervision expertise for biotech crops.…”

“…Intellectual property is also taken as an obstacle, however, through conducting some research in many developing countries, particularly in SSA, it can be seen that intellectual property is not necessarily an impediment that cannot overcome with (Farre et al, 2010;Bazuin et al, 2011). A third category of restricting factors that is observed in many developing nations, especially in SSA, comes up from unavailability of effective seed systems and seed markets, without agricultural support services, for farmers to promptly access enhanced genetics (Anthony and Ferroni, 2011).…”
