Book Description
Agricultural intensification has only taken off to a very limited extent in Ghana. Adoption of land productivity-enhancing technology is low, even in areas with proximity to urban markets. Rather, farmers have increasingly been adopting labor-saving technologies such as herbicides and mechanization, for which vibrant private supply channels are emerging. Further efforts to strengthen the private mechanization supply chain would help meet the rising demand for tractor services. Furthermore, mechanization could also help free up agricultural labor to perform other more labor intensive tasks.

Book Description
Ensuring a stable and healthful food supply for the world’s growing population has become increasingly urgent, particularly in the face of climate change. In spite of expected increases in food production in developing countries, the number of people at risk of hunger is predicted to grow, especially in the world’s poorest regions. While technology is not a panacea, it is critical to addressing the food production side of the food security equation. The social, economic, and other factors that affect technology adoption are complex and varied, requiring research that combines natural and social sciences to understand how best to influence the uptake and sustained use of effective technologies. Research should focus on four areas where complex combinations of challenges inhibit adoption. Understanding (1) farm-level, (2) economic, and (3) policy barriers would illuminate where promising innovations may be viable. Further, researchers should explore which approaches most effectively drive adoption of (4) combinations of agricultural practices and technologies.

Book Description
The adoption of machinery in agricultural production in Africa south of the Sahara has been far behind the level of mechanization found in Asia and Latin America. However, recent survey data have revealed high levels of machinery use in localized areas of cereal production in northern Ghana. A survey conducted by the International Food Policy Research Institute, in partnership with the Savannah Agriculture Research Institute, found that in some areas more than 80 percent of farmers were using machinery for at least one operation. This paper considers the theoretical drivers of agricultural intensification, as outlined by Boserup, Pingali, and Binswanger, and the extent to which they are able to explain the spatial variation in machinery use found in northern Ghana. Population pressure, market access, and agroecological conditions are considered key drivers that cause farmers to find ways to increase productivity and adopt new technologies. Combining survey data with geospatial datasets, the empirical analysis finds that population growth and travel time to the local urban center explain a significant and large proportion of the variation in machinery use by farmers.

Book Description
Essay one evaluates two farmer field schools aimed at promoting conservation agricultural practices. The field schools were conducted and offered to approximately 1/3 of all individuals surveyed in a baseline in 2010. These same farmers were resurveyed in 2012 in order to determine whether their knowledge of conservation agriculture practices had changed using a double-difference approach. The approach was also used to determine whether innate perceptions and biases against conservation agriculture have changed over time due to training in the field schools. These findings are supported with enterprise budgets of conservation practices to determine whether knowledge or on-farm economics limit adoption of conservation practices. The data showed that farmer-to-farmer communications are effective tools for raising knowledge. Essay two examines the interdependence of sustainable agricultural intensification practices (SAIPs) in order to better understand the constraints and incentives for the adoption of components and "packages" of components. The impact of accumulated knowledge score on the adoption of SAIPs was assessed using data from 168 participant and non-participant farm households that completed a survey in 2014 and 2012 from the Upper West region of Ghana. From a three-step regression, our findings show knowledge of participant household improved with evidence of knowledge spillover to non-participant. Participation, age and gender of the head of household and experience were factors impacting farm household knowledge score change on SAIPs. The study found that, knowledge score through the treatment effect impacts adoption of SAIPs which are complementary. Younger household heads and experience in farming are also found to likely impact adoption. Essay three estimates technical efficiency (TE) scores for millet and sorghum and evaluates the impact of soil and water conservation methods on TE scores. The paper also examines the sensitivity of TE scores on the distributional assumptions of the one-sided error using data from 518 and 754 farm households producing millet and sorghum respectively from a random national household survey in Niger. A Cobb-Douglas stochastic frontier model was used. The mean TE scores range from 52% to 66% and 35% to 60% respectively for adopters and non-adopters of soil and water conservation methods in millet production based on the distributional assumptions of the one-sided error. For sorghum production, the mean TE scores range from 47% to 63% and 39% to 63% respectively for adopters and non-adopters of soil and water conservation methods based on the distributional assumptions of the one-sided error. This suggests inefficiencies in the production of millet and sorghum and hence, the potential to improve output using existing technology. Adopters are relatively more efficient than non-adopters of soil and water conservation methods. The TE score differences in millet production are explained by location of household (rural), educational level and adoption of soil and water conservation. The efficiency score differences in sorghum can be explained by household size, educational level and soil and water conservation adoption. We also found TE scores are sensitive to the distributional assumptions of the one-sided error using the farm household level data.

Book Description
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.

Book Description
This volume deals with land degradation, which is occurring in almost all terrestrial biomes and agro-ecologies, in both low and high income countries and is stretching to about 30% of the total global land area. About three billion people reside in these degraded lands. However, the impact of land degradation is especially severe on livelihoods of the poor who heavily depend on natural resources. The annual global cost of land degradation due to land use and cover change (LUCC) and lower cropland and rangeland productivity is estimated to be about 300 billion USD. Sub-Saharan Africa (SSA) accounts for the largest share (22%) of the total global cost of land degradation. Only about 38% of the cost of land degradation due to LUCC - which accounts for 78% of the US$300 billion loss – is borne by land users and the remaining share (62%) is borne by consumers of ecosystem services off the farm. The results in this volume indicate that reversing land degradation trends makes both economic sense, and has multiple social and environmental benefits. On average, one US dollar investment into restoration of degraded land returns five US dollars. The findings of the country case studies call for increased investments into the rehabilitation and restoration of degraded lands, including through such institutional and policy measures as strengthening community participation for sustainable land management, enhancing government effectiveness and rule of law, improving access to markets and rural services, and securing land tenure. The assessment in this volume has been conducted at a time when there is an elevated interest in private land investments and when global efforts to achieve sustainable development objectives have intensified. In this regard, the results of this volume can contribute significantly to the ongoing policy debate and efforts to design strategies for achieving sustainable development goals and related efforts to address land degradation and halt biodiversity loss.

Book Description
Maize is an important food crop in Ghana, accounting for more than 50 percent of the countrys total cereal production. The Ghana Grains Development Project (19791997) and the Food Crops Development Project (20002008) made major investments to improve maize yield. Despite these efforts, the average maize yield in Ghana remains one of the lowest in the world, much lower than the average for Africa south of the Sahara.

Book Description
This paper assesses whether fertilizer subsidy programs can be better targeted to resource-poor farmers using the case of Ghana and proxy means test approaches. Past fertilizer subsidy programs in the country have not been particularly targeted to the poor, even as targeting poor and smallholder farmers has become key in the program implementation guidelines. As a result, many poor farmers have not benefited from past programs. Our results show that targeting approaches based on proxy means tests that use the correlates of poverty to select beneficiary farmers can potentially improve the poverty outreach and costeffectiveness of Ghana’s fertilizer subsidy programs. Therefore, we propose that the proxy means test approach should be considered for implementing Ghana’s fertilizer subsidy programs, first in a pilot project involving a few communities, and later, if found successful, in a full-scale program.
