Book Description
The FAO estimated that five out of six farms in the world are operating less than two hectares of land, suggesting that small-holder farmers are producing over one-third of the global food. The cropping systems practiced by smallholder farmers play a vital role in agri-food production systems and help to reduce hunger, improve nutrition, and provide livelihoods to millions across the developing countries. The performance of these cropping systems has a direct impact on achieving the multiple Sustainable Development Goals (2030) of No Poverty (SDG 1), Zero Hunger (SDG 2), and Good Health and Wellbeing (SDG 3). System intensification is now widely recognized as an essential pathway to achieve food and nutrition security in developing countries. The numbers of smallholder farmers are rapidly increasing in both developing and underdeveloped countries, however, they are increasingly facing challenges to run profitably. Cropping system intensification (CSI) could be one of the ways to make such production systems more remunerative for these farmers.

Book Description
Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems and institutional innovation. Much of the work represents outputs of the three CGIAR Research Programs on Integrated Systems for the Humid Tropics, Aquatic Agricultural Systems and Dryland Systems. The chapters are based around four themes: the conceptual underpinnings of systems research; sustainable intensification in practice; integrating nutrition, gender and equity in research for improved livelihoods; and systems and institutional innovation. While most of the case studies are from countries and agro-ecological zones in Africa, there are also some from Latin America, Southeast Asia and the Pacific.

Book Description
Africa can achieve self sufficiency in food production through adoption of innovations in the agriculture sector. Numerous soil fertility and crop production technologies have been generated through research, however, wide adoption has been low. African farmers need better technologies, more sustainable practices, and fertilizers to improve and sustain their crop productivity and to prevent further degradation of agricultural lands. The agricultural sector also needs to be supported by functional institutions and policies that will be able to respond to emerging challenges of globalization and climate change.

Book Description
Sustainability of rainfed cropping across southern Africa is undermined by maize (Zea mays L.) monocultures which are mostly cultivated on nitrogen (N) deficient soils. Smallholder farmers rarely achieve access to adequate quantities of inorganic fertilizers, and this limits crop productivity and negatively impacts food and nutritional security. Sustainable intensification with legumes has been proposed as a solution to address these challenges. Legumes such as groundnut (Arachis hypogaea L.) and pigeonpea (Cajanus cajan L.) potentially improve soil fertility and productivity of cereal crops grown in sequence through biological nitrogen fixation (BNF) and high-quality organic residues. However, successfully addressing smallholder farmer challenges requires understanding cropping system performance on-farm, in different environments. This is critical for site-specific agricultural technology recommendations that suit smallholder farmer goals.This dissertation consists of three studies on sustainable intensification with legumes in maize-legume cropping systems in central and southern Malawi. A participatory research approach of researcher designed, and farmer-managed trials were used to evaluate legume and maize production, the economic feasibility of cropping systems, BNF contributions and effect of residue quality and quantity on soil N dynamics. In the first chapter, four cropping systems in on-farm experiments, in five locations from three agroecologies in central Malawi were used to compare intercrop diversity and rotational diversity. The objective of the study was to determine suitable cropping systems for smallholder farmers in terms of grain production and economic viability. Above and belowground biomass was monitored to understand inter- and intra-specific competition of pigeonpea, and groundnut compared to the traditional maize/pigeonpea intercrop. Pigeonpea biomass was suppressed when intercropped with either groundnut or maize, whereas groundnut was not sensitive to interspecific competition. The second chapter is an evaluation of on-farm nitrogen dynamics, including a detailed assessment of BNF by plant tissue components of groundnut and pigeonpea within four legume-maize diversified cropping systems in central Malawi. The findings show that the net nitrogen balance with groundnut varied markedly, from deficit to a net benefit for subsequent crops, depending on growth and residue management. Another finding was that pigeonpea, especially when grown as part of a doubled-up legume system, provided substantial nitrogen inputs on rain-fed smallholder farms. The third chapter involved determining the effect of incorporating high- vs low-quality and quantity of crop residues on mineral N dynamics and subsequent maize yield in southern Malawi. Findings show the actual crop residue biomass quantity and quality that smallholder farmers are capable of producing depending on their biophysical environment. Each of the three studies highlights implications for on-farm sustainable intensification with legumes to address various farmer goals in different environmental context.
