Environmental Impacts of Food Loss and Waste: Land Degradation
(2021-02-23)
Food waste and loss have a negative impact on the environment through water, land, energy and other natural resources that are used to produce non-consumable products. According to the results of an empirical study, to establish the degree of degradation of land resources as a result of food loss and waste, as well as to identify potential environmental benefits from reducing food loss and waste for agricultural land use. Methods: The authors’ methodological approach for assessing the impact of food loss and waste ...

A comparative cost-benefit analysis between fairtrade certified and non-certified cocoa production in the South-West region of Cameroon
(2021-12-31)
In order to promote cocoa agroforestry by encouraging cocoa farmers to integrate fruit trees inside their cocoa orchards, cocoa certification was initially launched since 2012 in Cameroon. Nowadays, cocoa certification is adopted by a few farmers and makes up only 3% of the national cocoa production. Using the most predominant Fairtrade certification in the South-West region, this study compared certified and non-certified cocoa production via a cost-benefit analysis. The results indicated that, in spite of its ...

Effect of different mechanical seed scarification methods on germination and emergence dynamics of baobab (Adansonia digitata L.)
(2021-10-28)
The African baobab (Adansonia digitata L.) is a multipurpose fruit-producing tree that is indigenous to the African savannahs. Commercial interest in the species has grown in recent years. The major obstacle of seed-based propagation of baobab is its inherent seed dormancy. Therefore, in this study the effects of different mechanical seed scarification methods on seed germination parameters and seedling development of A. digitata were tested. The results show that mechanical scarification had a significant effect on ...

Growth performance and immunological response of African Catfish (Clarias gariepinus) juveniles reared in biofloc system
(2021-06-08)
This study was conducted to examine the growth and immune performance of catfish (Clarias gariepinus) juveniles cultured in a biofloc fish farming system. To achieve this, 900 C. gariepinus juveniles (9.0 ± 0.23 g) were cultured in an intensive zero water exchange biofloc system for 72 days in 9 separate tanks (2 m3 each) aerated by an air blower, after which growth assessment of fish was conducted. The trial consisted of three treatments in triplicates, a control without carbon source addition, and two biofloc ...

Mixed method survey of vegetable farming and rural farmers’ livelihood in Enugu State, Nigeria
(2021-12-07)
Studies on the role of agriculture on the improvement of livelihood of farmers have primarily focused on staple crops. Increased awareness on the importance of vegetables in urban and rural areas in Nigeria has led to a rise in demand of vegetables. In both rural and urban communities, smallholder farmers are responding to this demand by increasing vegetable production and thereby creating economic opportunity for themselves. The purpose of this paper is to assess the role of vegetable farming on rural farmers’ ...

Assessment of pond and integrated aquaculture (IAA) systems in six districts of Tanzania
(2021-06-04)
Integrated agriculture and aquaculture systems (IAA) are well known for their ability to improve the overall farm productivity and profitability. This is through recycling of on-farm resources, such as nutrient rich fish pond water and agriculture remains that would otherwise be considered as wastes. The present study explores the existing and potential IAA systems in Tanzania. It also examines management strategies and their influence on fish yield and the economic returns between IAA and non-IAA fish farming. The ...

Choice of savings instruments among rural women maize farmers: evidence from Uganda
(2021-05-25)
Households in developing countries employ a wide range of mechanisms for making cash and in-kind (goods and services) savings which are either formal or informal. Yet, literature on how choices about appropriate savings instruments are made remains scanty. We examine the patterns and choice of these saving instruments using household data from women farmers in eastern Uganda. In particular, the paper focuses on the choice between formal cash saving instruments like commercial banks, village savings and loans associations ...

Demonstration of improved feed trough for efficient feed utilisation by small ruminants in Southern Mali
(2021-12-21)
The ruminant feeding systems of smallholder farmers in mixed crop and livestock systems in Sudano-Sahelian zone of West Africa are characterised by waste. To promote efficient feed use, the use of improved feed trough for small ruminants was demonstrated in Sirakele, Zanzoni and M’Pessoba in Koutiala district in southern Mali in the late (March/April 2019) and early dry (February 2020) seasons. Forty-five farmers were selected randomly in the study sites and were each provided with one improved feed trough which was ...

Demand for selected plant-based protein among the staff of a tertiary institution in Nigeria
(2021-09-29)
Increasing demand for animal protein has a negative consequences human health and the environment. Thus, the need for a replacement of animal protein with plant-based protein in human diet. The demand for selected plant-based protein (PBPs) (soybean, mushroom, potato, and cowpea) was therefore assessed. Data collected from 343 staffers of university of Ibadan were analysed using descriptive statistics and Quadratic Almost Ideal Demand System. Mushroom and soybean were luxury goods but demand for mushroom was more ...

Agroecological heuristics: Xi (Ξ) biomathematical models of alpha diversity and Lambda functional entropy index (λ) applied for macrofauna in diversified agroecosystems of Nicaragua
(2021-12-08)
Agriculture causes chaos on the macrofauna associated with agroecosystems. The functions developed by macrofauna species in agroecological environments are harmful, beneficial and fundamental for food production. In order to design Xi (Ξ) biomathematical models of alpha diversity and to create a functional entropy index (λ), the taxonomic identification of macrofauna was carried out in 10 agroecosystems with conventional and agroecological production approach in five locations of Nicaragua: Boaco, Carazo, Chinandega, ...
