The technical efficiency involved in cocoa production in Cross River State was estimated using the stochastic frontier production function analysis. The effects of some selected socio- economic characteristics of the farmers on the efficiency indices were also estimated. The study relied upon primary data generated from interviewing cocoa farmers using a set of structured questionnaire. A multi...

The goal of this paper is to introduce an adjoint approach for calculating stream depletion in a river that is hydraulically connected to an aquifer. This paper presents the coupled forward and adjoint equations of flow in an unconfined aquifer, a confined aquifer, and in a river. Flow in the river is assumed to follow Manning’s equation, and the river is assumed to have a wide, rectangular cro...

Grassroots initiatives that aim to defend, protect, or restore rivers and riverine environments have proliferated around the world in last three decades. Some of most emblematic are anti-dam anti-mining movements been framed, by large, as civil society versus state movements. In this article, we bring nuance such framings analyzing broader diverse river-commoning state–citizens relations underl...

The study was carried out to determine profitability of broiler production in Cross River State, Nigeria. A three stage multi sampling technique adopted the selection 180 respondents. Data collected were analysed using descriptive statistics such as frequency, mean, ranking and percentages, well budgeting techniques tools net farm income (NFI), return naira invested (RNI), gross operating ratio...
