Genetic conservation and improvement depends (among other things) on the action of local people (CBD, 1994). We know that farmers are extremely knowledgeable about their crops and that they continuously experiment with them and with new materials arriving from various sources (Richards, 1989). Certain farmers are locally recognised as having “expert” knowledge about agro-biodiversity. They are ...

Conservation strategies are increasingly driven by our understanding of the processes and patterns of gene flow across complex landscapes. The expansion of population genetic approaches into traditional agricultural systems requires understanding how social factors contribute to that landscape, and thus to gene flow. This study incorporates extensive farmer interviews and population genetic ana...

Potential growth of dairy sector is highest and more reliable compared to crop sector, indicating that dairy sector can play vital role to increase income among farmers in rural areas than crop sector in Sri Lanka. Credit and farmer training in management ability have been major concerns of dairy development efforts. Therefore, this study wasconductedto assess the impact of credit and farmer tr...

Because the farmer is typically excluded from the experimental research setting, experimental research may face challenges in evaluating pest management tactics whose costs and benefits hinge on farmer decision-making. In these cases an ecoinformatics approach, in which observational data collected from the commercial farming setting are "mined" to quantify both biological variables and farmer ...

Arguments about the causes of Indian farmer suicides have been widely aired in recent years, both in the media and in academic papers. It is plausible to suppose, as Carleton (1) does, that climate change has an indirect causal effect on the farmer suicide rate via reduced crop yields and increasing debt. It is, however, much less plausible to suppose that there will be a causal link for nonfar...

The global agricultural economy is changing. Commodity prices are declining, and producers increasingly supply complex value chains. There is growing interest in how farmers can benefit from emerging market opportunities. Farmers are encouraged to produce high value crops and engage in value-adding activities such as agro-processing. Farmer organization and collective action are often seen as k...

This paper describes an implementation of a large heterogeneous distributed parallel computation that counts the distribution of twin primes and calculates Brun’s constant and maximal distances between pairs of twin primes. Two primes are twins if they differ by two. It is not known if there are infinitely many twin primes but it was proven that the sum of their inverses converges to the value ...
