Description : Read Now Sustainable Intensification by Jules N. Pretty and you can download with pub, pdf, txt, doc, and more file format with free account. 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.

Description : Read Now Soil Management Of Smallholder Agriculture by Rattan Lal and you can download with pub, pdf, txt, doc, and more file format with free account. nearly two billion people depend on hundreds of millions of smallholder farmers for food security. yet, these farmers’ lives also hang in the balance due to their extreme vulnerability to the risks of soil degradation and depletion, soil exhaustion, climate change, and numerous biotic and abiotic stresses. soil management of smallholder agriculture explores the potential smallholder agriculture hold for advancing global food security and outlines the challenges to achieving this goal. the book addresses the challenges and opportunities that resource-poor and small landholders face and provides recommended management practices to alleviate soil-related constraints, and increase and sustain crop yield and production. it discusses the cultural, economic, social, and technological aspects of sustainable soil management for smallholder farmers. it then examines soil-related and institutional constraints, principles of sustainable agriculture, soil quality improvement, nutrient and soil fertility management, soil carbon sequestration, soil security, efficient use of resources, and agronomic production. edited by experts, the book makes the case for the adoption of proven technologies of sustainable intensification, producing more from less, both for advancing agronomic production and adapting to changing climate. it outlines a strategy that will usher in a soil-based green revolution by increasing the use efficiency of energy-based inputs such as fertilizers, pesticides, and irrigation to restore soil quality, and sequestering carbon in the terrestrial ecosystems. this strategy helps small farms narrow the gap between the actual and attainable crop yield.

Description : Read Now Sustainable Intensification And Diversification Options With Grain Legumes For Smallholder Farming Systems In The Guinea Savanna Of Ghana by no defined and you can download with pub, pdf, txt, doc, and more file format with free account. food security is a critical issue in the guinea savanna of ghana where about 60% of the rural population, mostly smallholder farmers are food insecure. food insecurity results from poor crop yields due to low soil fertility compounded by erratic unimodal rainfall and the inability of households to purchase required supplemental food. rapid population growth means that the numbers of food insecure people are likely to increase, necessitating sustainable intensification and diversification to increase crop production per unit area of land. this thesis focused on testing spatial and temporal intensification and diversification options suitable for the variable biophysical and socio-economic conditions of smallholder farming systems in the guinea savanna to increase productivity, mitigate the risk of crop failure, and thus to increase food self-sufficiency. one site in the southern guinea savanna and one in the northern guinea savanna were selected which differed in biophysical and socio-economic resources. in each site, field experiments were conducted on three fields differing in soil fertility (fertile, medium fertile, poorly fertile) to quantify: n2-fixation and n contribution to soil fertility by grain legumes in sole and intercropping; impact of replacement intercropping on increasing resource use efficiency and crop productivity; and productivity of relay (additive) intercropping and rotation of grain legumes with maize. scenario analysis was performed with data from the n2africa ghana project supplemented with data from the on-farm experiments and literature to test the impacts of intensification and diversification options on household food self-sufficiency. sole legumes fixed larger amounts of n2 than under intercropping. the soil n balance was generally positive and similar between intercrops and sole crops suggesting that both systems could be sustainable intensification and diversification options. poor fields stimulated grain legumes to rely on atmospheric n2 for growth leading to more positive soil n balances than in fertile fields. consequently, legumes in poor fields were more competitive with maize and led to greater intercrop yield advantage than in fertile fields. across all fields and sites, intercropping enhanced the efficiency in resource use resulting in a 26% to 46% yield advantage over sole cropping. intercrops were more efficient and productive in the drier northern guinea savanna than in the wetter southern guinea savanna. yet the absolute larger grain yields achieved in fertile fields and in the southern guinea savanna with more favourable soil fertility and rainfall resulted in greater net benefits. this suggests that intercropping is beneficial both in poorly fertile and fertile fields though the benefits take different dimensions. legume-cereal rotation was superior in increasing the yield of maize without n fertiliser ranging from 0.38 t ha-1 in ngs to 1.01 t ha-1 in sgs due to residual n and non-n benefits compared with continuous maize cropping. sowing cowpea first and relaying maize decreased maize grain yield substantially from 0.29 t ha-1 (14%) in sgs to 0.82 t ha-1 (83%) in ngs, representing 14% and 83% grain yield reductions relative to maize sown at the beginning of the season. these grain yield reductions were due to inadequate rainfall received by the relay maize. when maize was sown from the onset of the season and the cowpea relayed, the cowpea grain yield reduction was relatively smaller compared with that of maize. such cowpea grain yield decline was similar between the sgs and ngs and ranged from 28% (0.18 t ha-1) to 47% (0.26 t ha-1) relative to the cowpea sown from the onset of the season. the cumulative grain yield of this relay system over two seasons was similar to that of the legume-cereal rotations even with cowpea failing to yield in the first season. the scenario analysis revealed a high incidence of food insufficiency among smallholder farm households in the guinea savanna of ghana. this ranged from 56% in the northern region with relatively favourable rainfall, soil fertility and larger land area cropped per farm to 45% in the upper east and upper west regions with comparatively less rainfall, poor soils and smaller land area cropped. in addition, 21% of households in the northern region and 37% in the upper east and upper west regions could only survive on their own food production for six months or less. however, the scenario analysis suggested that through intensification and diversification with grain legumes, the proportion of food self-sufficient households in the guinea savanna could increase by 25 – 43% and those self-sufficient for a maximum of half a year decreased to 3 – 15%. households could also generate substantial marketable surpluses to earn income. however, the total size of land cropped by a farm household matters, and improved access to markets and credit are needed to acquire the relevant inputs. also, multi-year analysis using modelling would be relevant in providing insights on long-term nutrient balances, especially of n and soil organic matter to understand the long-term sustainability of the various options.

Description : Read Now Sustainable Intensification Of Agriculture by Jules Pretty and you can download with pub, pdf, txt, doc, and more file format with free account. sustainable intensification (si) has emerged in recent years as a powerful new conceptualisation of agricultural sustainability and has been widely adopted in policy circles and debates. it is defined as a process or system where yields are increased without adverse environmental impact and without the cultivation of more land. co-written by jules pretty, one of the pioneers of the concept and internationally known and respected authority on sustainable agriculture, this book sets out current thinking and debates around sustainable agriculture and intensification. it recognises that world population is increasing rapidly, so that yields must increase on finite land and other resources to maintain food security. it provides the first widely accessible overview of the concept of si as an innovative approach to agriculture and as a key element in the transition to a green economy. it presents evidence from around the world to show how various innovations are improving yields, resilience and farm incomes, particularly for ‘resource constrained’ smallholders in developing countries, but also in the developed world. it shows how si is a fundamental departure from previous models of agricultural intensification. it also highlights the particular role and potential of small-scale farmers and the fundamental importance of social and human capital in designing and spreading effective innovations.

Description : Read Now Food For All In Africa by Gordon Conway and you can download with pub, pdf, txt, doc, and more file format with free account. africa requires a new agricultural transformation that is appropriate for africa, that recognizes the continent's diverse environments and climates, and that takes into account its histories and cultures while benefiting rural smallholder farmers and their families. in this boldly optimistic book, sir gordon conway, ousmane badiane, and katrin glatzel describe the key challenges faced by africa's smallholder farmers and present the concepts and practices of sustainable intensification (si) as opportunities to sustainably transform africa's agriculture sector and the livelihoods of millions of smallholders. the way forward, they write, will be an agriculture sector deeply rooted within si: producing more with less, using fertilizers and pesticides more prudently, adapting to climate change, improving natural capital, adopting new technologies, and building resilience at every stage of the agriculture value chain. food for all in africa envisions a virtuous circle generated through agricultural development rooted in si that results in greater yields, healthier diets, improved livelihoods for farmers, and sustainable economic opportunities for the rural poor that in turn generate further investment. it describes the benefits of digital technologies for farmers and the challenges of transforming african agricultural policies and creating effective and inspiring leadership. food for all in africa demonstrates why we should take on the challenge and provides ideas and methods through which it can be met.
