Factors Affecting Adoption of Improved Maize Seeds and Use of Inorganic Fertilizer for Maize Production in the Intermediate and Lowland Zones of Tanzania


Book Description

This paper examines factors influencing the adoption of improved maize seeds and the use of inorganic fertilizer for maize production by farmers in the intermediate and lowland zones of Tanzania. The results indicate that availability of extension services, on-farm field trials, variety characteristics and rainfall were the most important factors that influenced the extent of adopting improved maize seeds and the use of inorganic fertilizer for maize production. Farmers preferred those varieties which minimize field loss rather than maximizing yields. Future research and extension policies should emphasize farmer participation in the research process and on-farm field trials for varietal evaluation and demonstration purposes. Key Words: adoption, agroecological zones, improved maize seeds, new technology, Tanzania.







Fertilizer Quality and its Impacts on Technical Efficiency and Use Intensity in the North China Plain


Book Description

Fertilizer has helped the growth of agriculture for decades. However, its overuse in some regions has caused environmental and health problems due to pollution and contamination of groundwater. Fertilizer quality is another cause for concern in many countries, as the actual nutrient content may not match the labeled content on the packaging. The North China Plain is a region affected by both fertilizer overuse and quality problems. This study delves into the issue using economic models and survey data of farm households. Is the effectiveness of fertilizer overstated? How do farmers respond to uncertainty in fertilizer quality? Can they differentiate between good and poor quality fertilizer?







Decentralization, agricultural services and determinants of input use in Nigeria


Book Description

The substantial differences in agricultural productivity between Asia and Africa can be largely explained by differences in use of modern inputs. The evidence suggests that better access to infrastructure (such as roads and irrigation) and agricultural services has given Asian farmers significantly better access to modern inputs, while Sub-Saharan African farmers without such an access are not able to fully exploit the benefits of modern agricultural inputs. This brief discusses the relationship between agricultural service provision and modern input use by farmers in Nigeria, with a focus on the differences among states and local government areas (LGA).




Agriculture and Ecosystem Resilience in Sub Saharan Africa


Book Description

This volume discusses emerging contexts of agricultural and ecosystem resilience in Sub Saharan Africa, as well as contemporary technological advances that have influenced African livelihoods. In six sections, the book addresses the sustainable development goals to mitigate the negative impacts on agricultural productivity brought about by climate change in Africa. Some of the challenges assessed include soil degradation, land use changes, natural resource mismanagement, declining crop productivity, and economic stagnation. This book will be of interest to researchers, NGOs, and development organizations. Section 1 focuses on climate risk management in tropical Africa. Section 2 addresses the water-ecosystem-agriculture nexus, and identifies the best strategies for sustainable water use. Section 3 introduces Information Communication Technology (ICT), and how it can be used for ecosystem and human resilience to improve quality of life in communities. Section 4 discusses the science and policies of transformative agriculture, including challenges facing crop production and management. Section 5 addresses landscape processes, human security, and governance of agro-ecosystems. Section 6 concludes the book with chapters uniquely covering the gender dynamics of agricultural, ecosystem, and livelihood resilience.







An innovation systems approach to enhanced farmer adoption of climate-ready germplasm and agronomic practices


Book Description

By 2050, climate change is likely to reduce maize production globally by 3–10 percent and wheat production in developing countries by 29–34 percent. Even without climate change, the real costs of wheat and maize will increase by 60 percent between 2000 and 2050; climate change could make the figure substantially greater. Food security, despite the above, may be possible if agricultural systems are transformed through improved seed, fertilizer, land use, and governance.




The Perception of and Adaptation to Climate Change in Africa


Book Description

Abstract: The objective of this paper is to determine the ability of farmers in Africa to detect climate change, and to ascertain how they have adapted to whatever climate change they believe has occurred. The paper also asks farmers whether they perceive any barriers to adaptation and attempts to determine the characteristics of those farmers who, despite claiming to have witnessed climate change, have not yet responded to it. The study is based on a large-scale survey of agriculturalists in 11 African countries. The survey reveals that significant numbers of farmers believe that temperatures have already increased and that precipitation has declined. Those with the greatest experience of farming are more likely to notice climate change. Further, neighboring farmers tell a consistent story. There are important differences in the propensity of farmers living in different locations to adapt and there may be institutional impediments to adaptation in some countries. Although large numbers of farmers perceive no barriers to adaptation, those that do perceive them tend to cite their poverty and inability to borrow. Few if any farmers mentioned lack of appropriate seed, security of tenure, or market accessibility as problems. Those farmers who perceive climate change but fail to respond may require particular incentives or assistance to do what is ultimately in their own best interests. Although experienced farmers are more likely to perceive climate change, it is educated farmers who are more likely to respond by making at least one adaptation.
