Available in PDF, EPUB and Kindle. Book excerpt: Degraded and infertile soil, low agricultural productivity, and food and nutrition insecurity are persistent and major challenges facing many countries in sub-Saharan Africa (SSA) up to this day. Agricultural sustainable intensification (SI) has been proposed as a possible solution to simultaneously address these challenges. Yet, there is little empirical evidence on whether SI indeed improves households' incomes, nutrition, and food security. The three essays in this dissertation take various quasi-experimental approaches to investigate child nutrition and household food security effects of SI and examine the role of input subsidies in promoting SI using nationally-representative household panel survey data from Tanzania. In the empirical analysis, I focus on three important soil fertility management (SFM) practices in Tanzanian maize-based production systems: the use of inorganic fertilizer, the use of organic fertilizer, and maize-legume intercropping. I group the eight possible combinations of these technologies into four SI categories: i) "Non-adoption" (use of none of the practices), ii) "Intensification" (use of inorganic fertilizer only), iii) "Sustainable" (use of organic fertilizer, maize-legume intercropping, or both), and iv) "SI" (joint use of inorganic fertilizer with organic fertilizer and/or maize-legume intercropping). This categorization is used in all three essays. In essay 1, results from a multinomial endogenous treatment effects model suggest that the use of practices in the "SI" category is consistently associated with improvements in children's height-for-age z-score and weight-for-age z-score, particularly for children beyond breastfeeding age (i.e., those age 25-59 months). I also find evidence that these effects come through both productivity and income pathways, and that the combined use of inorganic fertilizer and maize-legume intercropping is a key driver of these effects on child nutrition.Essay 2 investigates the extent to which the use of practices in each SI category influences household net crop income (per acre and per adult equivalent) and crop productivity as well as household food access (modified household dietary diversity score (HDDS), food expenditure per adult equivalent, and food consumption score (FCS)). Results from a multinomial endogenous switching regression model suggest that relative to "Non-adoption", use of practices in each of the other SI categories has a positive and significant effect on a household's net crop income-related outcomes and crop productivity. Importantly, for these outcomes, the "SI" category has either larger or similar-in-magnitude effects compared to "Intensification", and consistently larger effects than "Sustainable" practices. The results further suggest that a household's use of packages in the "SI" category is significantly associated with increases in all three food access outcomes, with the size of these effects similar to or greater than those of "Sustainable" practices and consistently larger than the effects of "Intensification". Essay 3 explores whether Tanzania's input subsidy program (ISP) from 2008 to 2014, the National Agricultural Input Voucher Scheme (NAIVS), encouraged or discouraged farmers' use of practices in the various SI categories on their maize plots using a multinomial logit model combined with the control function approach. I find statistically significant positive effects of household receipt of a NAIVS voucher for inorganic fertilizer on maize-growing households' use of inorganic fertilizer only (i.e., "Intensification") and on their combined use of inorganic fertilizer with organic fertilizer and/or maize-legume intercropping (i.e., "SI"). On the other hand, no such effects are found for the "Sustainable" category.

Download or read book Sustainable Intensification written by Jules N. Pretty and published by Routledge. This book was released on 2012-06-25 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Download or read book Sustainable Intensification for Food Security and Climate Change Adaptation in Tanzania written by Patrick Ryan Bell and published by . This book was released on 2016 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 70% of Tanzanians live on less that $2 per day and over 75% of the population is involved in agriculture. Increasing agricultural productivity is seen as a way to decrease poverty and stimulate the economy. Sustainable Intensification (SI) is widely promoted as a means to sustainably increase agricultural production for smallholder farmers. Practices considered being SI should increase productivity on the same land with more efficient use of resources, in a way that minimizes negative effects on the environment. The objectives of these studies were to evaluate SI practices for their effect on agronomic productivity and soil quality for smallholder farmers in Tanzania. Further, these studies sought to identify the impact that these practices have on smallholder farmer profitability and water management within an irrigation scheme. These objectives were achieved through experiments carried out at three locations over three growing seasons within the Lower Moshi Irrigation Scheme (LMIS) in Mabogini Village, Kilimanjaro Region, United Republic of Tanzania. The studies each evaluated improved cropping systems that are appropriate for various areas within the scheme. The first three studies evaluated the System of Rice Intensification (SRI), crop rotations and nutrient management strategies, and reduced tillage for their effect on agronomic productivity and soil quality. Two further studies evaluated the profitability of SRI and the occurrence of dry spells in the region and the implications this has for rainfed maize (Zea mayes) production. Within continuous rice (Oryza sativa), SRI and conventional had similar yields to those under conventional practices in the region except for during the last season, in which SRI systems yielded on average 1.25 Mg ha-1 higher than conventional systems. If SRI is adopted throughout the LMIS, there is potential to increase rice production by 4,173 Mg due to increased water use efficiency and the ability to increase the area under rice production. This translates into a potential net income in the region of $622,000 annually. The study evaluating crop rotations indicated that improved nutrient management resulted in higher yields regardless of other management practices. However, in rice-maize rotations, these studies indicate that bulk density and effective rooting depth issues will need to be addressed over the long term as they both violate critical limits established for maize production in tropical soils. The dry spell occurrence analysis indicated that the region is under a dry spell of greater than 15 days for 63% of the seasons analyzed. However, while maize yields under reduced tillage and supplemental irrigation were not significantly different from conventional tillage, all treatments received supplemental irrigation and yields ranged from 3.5-4.1 Mg ha-1—4 fold higher than current farmer yields. While rainfed maize is not feasible in the region, effective water management and supplemental irrigation can increase production in the area and should be explored further. Results from all the studies underline the importance of field-testing agricultural technologies within the context they are to be promoted and used. Overall, SI practices can be appropriate to farmers in the region but will require modification to ensure long-term sustainability.

This book was released on 2019-03-13 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This framework presents ten interrelated principles/elements to guide Sustainable Agricultural Mechanization in Africa (SAMA). Further, it presents the technical issues to be considered under SAMA and the options to be analysed at the country and sub regional levels. The ten key elements required in a framework for SAMA are as follows: The analysis in the framework calls for a specific approach, involving learning from other parts of the world where significant transformation of the agricultural mechanization sector has already occurred within a three-to-four decade time frame, and developing policies and programmes to realize Africa’s aspirations of Zero Hunger by 2025. This approach entails the identification and prioritization of relevant and interrelated elements to help countries develop strategies and practical development plans that create synergies in line with their agricultural transformation plans. Given the unique characteristics of each country and the diverse needs of Africa due to the ecological heterogeneity and the wide range of farm sizes, the framework avoids being prescriptive.

Download or read book Economic Analysis of Land Use in Global Climate Change Policy written by Thomas W. Hertel and published by Routledge. This book was released on 2009-05-07 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land has long been overlooked in economics. That is now changing. A substantial part of the solution to the climate crisis may lie in growing crops for fuel and using trees for storing carbon. This book investigates the potential of these options to reduce greenhouse gas emissions, estimates the costs to the economy, and analyses the trade-offs with growing food. The first part presents new databases that are necessary to underpin policy-relevant research in the field of climate change while describing and critically assessing the underlying data, the methodologies used, and the first applications. Together, the new data and the extended models allow for a thorough and comprehensive analysis of a land use and climate policy. This book outlines key empirical and analytical issues associated with modelling land use and land use change in the context of global climate change policy. It places special emphasis on the economy-wide competition for land and other resources, especially; The implications of changes in land use for the cost of climate change mitigation, Land use change as a result of mitigation, and Feedback from changes in the global climate to land use. By offering synthesis and evaluation of a variety of different approaches to this challenging field of research, this book will serve as a key reference for future work in the economic analysis of land use and climate change policy.
