Reduction in social benefits in form of fishery stock depletion has some fishing techniques seriously fingered as low economic performance among fisher folks is leading to low revenue and unemployment in Mangrove Swamp Zone (MSZ) of Nigeria. Data were obtained from a two-stage sampling technique from 206 artisanal fishermen in two states within MSZ. Data on fisher folks' socioeconomic features, adoption level of environmental sustainable fishing techniques (ESFT), quantity and unit selling prices of species of catch as well as inputs were elicited using a well-structured questionnaire and analyzed using both descriptive and budgetary tools. Majority (68.9% and 64.2%) of fishing activities are done with dugout canoes with only a few (16.0% and 16.7%) motorized vessels that goes further off-shore in Bayelsa and Rivers State respectively. Adption level of ESFT of 26.1% and 24.1% for Bayelsa and River State respectively is low. Nematopalaemon hastatis recorded the highest (46.6%) returns of USD 345.77/fisherman, as fleet dominated sea-shore for it. Though artisanal fishing in MSZ seems economically sustainable with benefit-cost across different adopters greater than unity and rate of returns to investment ratio of 1.37, ranging from 1.33 in Rivers to 1.44 in Bayelsa State, but poses a high marginal social cost to the breeding areas as catch is very concentrated at the sea shore of less than 5nm. There is a low catch of some pelagic species (Etamopterus penyl). The study recommends a persuasive extension demonstartion, litigation and the use water poilce to enforce strict adherence to principles ESFT for sustainable artisanal fishing activities in the mangrove region of Niger Delta.

Agriculture is the principal source of income for the majority of Nigerian rural households, but it has suffered significant setbacks in recent years, resulting in lower productivity and returns on investment. The study looked at the econometric analysis of household farmers' agricultural intensification strategies in Imo State, Nigeria. With the help of standardized questionnaires, 198 household farmers were selected using a multi-stage sample technique. The Beta regression model and descriptive statistics were used to analyze the data collected. Cassava, maize, and pumpkin leaves had the highest average outputs of 88.712kg, 87.901kg, and 85.990kg, respectively, which dominated the entire production cycle. Planting materials, soil nutrients, and land improvement activities cost the most, at N81.637. 75, N74, 402.82, and N71, 906.80, respectively. At 1% and 5% levels, the coefficients of age, sex, education, net farm income, farm size, extension contacts, and farming experience were statistically significant and influenced the intensification of sustainable agricultural techniques (SAT) in the area. The study recommends farmers to embrace effective and long-term agricultural technologies in order to boost farm production and output. Extension personnel should also meet with household farmers on a regular basis to communicate important information about new technologies.
