"The book gives a detailed description of the application of DSSAT in simulating crop and soil processes within various Agro-ecological zones in Africa. The book, an output of a series of 3 workshops, provides examples of the application of DSSAT models to simulate nitrogen applications, soil and water conservation practices including effects of zai technology, phosphorus and maize productivity, generation of genetic coefficients, long-term soil fertility management technologies in the drylands, microdosing, optimization of nitrogen x germplasms x water, spatial analysis of water and nutrient use efficiencies and, tradeoff analysis. The minimum dataset requirements for DSSAT is discussed. "

"This book elucidates the importance of long-term experiments in revealing evidence of soil fertility decline in Africa. An evaluation of experiences from on-going long-term experiments is given in broad detail. The first chapter explains the paradigm shift in soil fertility management then provides justification for long-term experiments before illuminating experiences from long-term experiments in East, West and Southern Africa. The second, sixth, eighth and ninth chapters give an in-depth account of crop management practices and soil fertility interventions in long-term trials within specific agro-ecological zones in West Africa. The rest of the chapters (chapter three, four, five and seven) address crop management, tillage practices and, organic and inorganic fertilizer applications in the context of long-term experiments in specific agro-ecological zones in East Africa."

"Cities are facing ever greater challenges regarding climate change. Urban governments and policymakers have taken such challenges into account when maintaining urban development momentum. Although the city government of Jakarta has implemented several initiatives to reduce emissions, assessments of the impact of these strategies on the sustainability of the urban system remain limited. This paper investigates the evaluation of two mitigation scenarios for reducing Jakarta’s greenhouse gases that differ in the authority level of the local government, using a policy analysis approach. The method emphasizes the use of the system dynamics model to gain insights into each option. The results reveal that the city’s development goals would be best achieved through joint partnership with the national government. Such cooperation would have a more significant effect on economic, social, and environmental sustainability than would be in the case in other scenarios."
