Fishers’ local ecological knowledge (LEK) can be used to reconstruct or supplement long-term trends in heavily exploited population or poorly assessed species with low biomass. We used historical memories of small-scale fishers to understand their perceptions of changes in catch trends in marine fisheries over the last 20 years. The study aimed at evaluating how fishers could provide consistent and reliable data on major fish...

This study was carried out to identify and compare the efficiency levels of maize growers using surface water irrigation (SWI) and groundwater irrigation (GWI) in Khyber Pakhtunkhwa, Pakistan. The variance inflation factor and Koenker Bassett test were used to check multicollinearity and heteroscedasticity that mostly occur in the primary data. The empirical findings obtained from the stochastic frontier analysis show that irr...
