Achieving a Climate-Change Resilient Farming System through Push–Pull Technology: Evidence from Maize Farming Systems in Ethiopia

Abstract: Building climate-resilient farming systems is important to promote the sustainability of agriculture at the global level. Scaling-up agroecological approaches in main staple crops, such as maize, is particularly important in enhancing the climate resilience of millions of smallholder farmers in developing countries. In this regard, push–pull technology (PPT) is an ecological approach to a farming system that aims to improve the climate resilience of maize producers in a smallhold...

LOCAL FARMING SYSTEMS AND FOOD SECURITY IN THE BUILSA AREA OF NORTHERN GHANA

ABSTRACT Societies are dynamic: so too are the farming systems that provide their food and other needs. The study examines transitions in farming systems and their contribution to food security at the household level. This is important as most people in rural areas rely on farming for their basic needs. These systems are under pressure from both external and internal forces with diverse impacts on food and livelihoods. A mixed-methods approach, which combined a survey with different qualitati...

Soil Nematode Communities Under Organic And Conventional Farming Systems In Chuka, Tharaka Nithi County, Kenya

ABSTRACT Plant parasitic nematodes (PPN) are biotic constraints to crop production worldwide resulting in significant yield losses. Management of these nematodes has primarily depended on chemical nematicides; but due to the increased pressure for more economic and environmentally friendly strategies, alternative methods like organic and conventional amendments, have been considered. To test the efficacy of conventional and farmer practice systems against organic farming in the suppression of...

Microbial Community Diversity And Structure Within Organic And Conventional Farming Systems In Central Highlands Of Kenya

ABSTRACT Microbial diversity and function in agro-ecosystems is influenced by various aspects linked to soil and agronomic practices for example, tillage, irrigation, crop rotation and application of organic and inorganic inputs. Farming systems practices may affect the dynamic interactions existing between soil, plant and microorganisms in different agricultural biomes. Due to limitations associated with conventional microbial cultivation strategies, only a fractional number of cultivable sp...

Adaptation To Rainfall Variability, Socioeconomic Factors Influencing Maize Production In Crop Livestock Mixed Farming Systems In Babati District, Tanzania

ABSTRACT Agriculture is an important source of food and economic survival of rural populations in Tanzania however farming activities are highly affected by rainfall variability which cause loss in crops and livestock yield. This study explored adaptation strategies to rainfall variability, socioeconomic factors influencing maize production in mixed farming systems. Specifically, assessed the trends in rainfall and maize production, determined the relationship between trends, identified farm...

Performance Evaluation and Environmental Impact Assessment of Systems with Waste Exergy Emissions.

Abstract— The transformation and utilization of non-renewable energies involves irreversibility which makes our system less efficient. The environmental impact potential is equivalent to the work potential of the emissions. The irreversibility of inefficient systems has Global Warming Potential or environmental impact potential as wasted exergy is not always in equilibrium with the environment. Most literatures have either considered the optimization of thermodynamic systems for better effi...

Organic maize and bean farming enhances free-living nematode dynamics in sub-Saharan Africa

Abstract: Despite their important ecological roles for soil health and soil fertility, free-living nematodes (FLN) have received relatively limited research attention. The present study evaluated the community structure and diversity of FLN in a field setting. The experiments were conducted in on-farm and on-station field plots sown to maize (Zea mays) and beans (Phaseolus vulgaris) under four cropping practices. These farming systems included organic (compost and biopesticide use), conventi...

Data-Driven Artificial Intelligence (AI) Algorithms for Modelling Potential Maize Yield under Maize–Legume Farming Systems in East Africa

Abstract: Agroecological farming systems such as maize–legume intercropping (MLI) and push-pull technology (PPT) have been introduced to mitigate losses from pests. Nevertheless, the regionwide maize yield gained from practicing such farming systems remains largely unknown. This study compares the performance of two uncomplex and interpretable models, namely the hybrid fuzzy-logic combined with the genetic algorithm and symbolic regression, to predict maize yield. Specifically, the study a...

Classification Of Chagga Agroforestry Homegardens And Their Contributions To Food, Income And Wood Energy To Communities Of Rombo District, Tanzania

ABSTRACT  The present study was carried out in 2014 in Rombo District, Kilimanjaro, Tanzania, in order to classify Chagga agroforestry home gardens and establish their relative contributions to food, income and wood energy to the local communities. The study methodology included random selection of four divisions, one ward from each division, one village from each ward and 30 households per village forming a total sample of 120 households. A social survey was subsequently carried out using q...

Economics of integrating push-pull technology in maize-dairy farming systems in eastern Uganda

Abstract: Cereals particularly maize, are the most essential food and cash crops for majority of smallholder households in Sub-Saharan Africa (SSA). In maize production, small-sized producers are confronted with different constraints including stemborers, Striga and degraded soil leading to poor crop yields. In response to these challenges, the International Centre of Insect Physiology and Ecology (icipe) and collaborators came up with a habitat management approach; the Push-pull Technology ...

Economic Analysis Of Smallholder Organic Vegetable Production System In Kiambu And Kajiado Counties Of Kenya

Abstract In Kenya, there are more than 200,000 farmers who have been trained on organic farming technologies and systems. Currently certified land under organic management in Kenya stands at 104,211 ha while the organic sub sector employs 12,647 farmers who are directly involved in production of different organic products. Although there are many documented reasons that make farmers to adopt organic farming system, economic benefits present one of the major motivations. These benefits however...

Effects Of Integrated Tree Based Food-Energy System On The Livelihoods Of Small-Holder Farmers’ Perceptions In Tharaka Nithi County, Kenya

ABSTRACT Tree Based Integrated Food-energy System is a farming system that combines food crops and trees for wood energy production on the same farm. This farming system aims at producing both food and wood energy on the same piece of land through sustainable crop integration and agro-systems. Therefore, this study was aimed at examining how this system can promote the livelihoods of small-holder farmers in Kenya, with particular focus on Chuka Igambang’ombe Sub-county in Tharaka Nithi Cou...

Evaluation Ofselected Management Practices Contributing To Primary Soil Greenhouse Gas Fluxes In Smallholder Sugarcane Farming In Lower Nyando, Westernkenya

ABSTRACT Human activities (including agriculture) contribute to enhance release of primary greenhouse gases (GHGs) (CH4, CO2, N2O) into the atmosphere leading to global warming. Sugarcane is an important economic crop in Kenya being third highest contributor to gross domestic product (GDP) after tea and coffee. About 90% of Kenya‘s production is contributed by smallholders. To improve/maximize sugarcane yields, farmers convert natural vegetation to sugarcane farms; apply nitrogen fertilizer...
