The last decade has seen a significant global increase in immigration. This large growth has caused an increasing opposition to immigration in local populations in many parts of the world, partly because of a commonly held belief that immigration increases crime. Using data from Chile, spanning 10 years, from 2005 to 2015, we analyze the relationship between immigration and crime through a dynamic Spatial Durbin Model (SDM), which accounts for the possible bias for omitted variables.

Global climate change will have a strong impact on Nigeria, particularly on agricultural production and associated livelihoods. Although there is a growing scientific consensus about the impact of climate change, efforts so far in Nigeria to deal with these impacts are still rudimentary and not properly coordinated. There is little evidence of any pragmatic approach towards tracking climate change in order to develop an evidence base on which to formulate national adaptation strategies.

Quantifying the impact of climate change at a regional scale is important in trying to develop adaptation policies. We estimated the economic impact of climate change on forest resource use in Nigeria using the Ricardian model in the STATA statistical software. Using a structured questionnaire, data were collected from 400 rural households in forest communities, sampled from five broad ecological regions across Nigeria to estimate income and potential impact on this as a result of climate change. Estimated average value of annual household income from the forest was $3380.

This research examined gender perspectives of the implications of the severe 2012 flood on household food security in rural Anambra state, Nigeria. Two hundred and forty flood-affected migrant households, made up of 120 maleheaded households (MHHs) and 120 female-headed households (FHHs) in four rural local government areas (LGAs) were interviewed using a questionnaire. In addition, 12 focus group discussions (FGDs) were conducted in the LGAs. Data analysis was by descriptive statistics, use of a food security index, and binary logistic regression.

The adoption of proven fish production management practices portends many economics and social implications. Interview schedule was employed to generate primary data from 146 respondents in the four cluster fish farms (estates) in two local government areas and analyzed with descriptive and inferential statistics. Information on socio economic characteristics revealed that most of the respondents were in the active age bracket of 30-40 years, well educated and small scale fish farmers with fewer years of experience members at fish farmers association and married.
