Conservation agriculture techniques can increase agricultural production while decreasing CO2 emissions, yet adoption in the developing world remains low—in part because many years of continuous adoption may be required to realize gains in production. We conduct a framed field experiment in northern Ghana to study how randomly assigned incentives and peer information may affect adoption. Incentives increase adoption, both while they are available and after withdrawal. There is no overall effect of peer information, but we do find evidence that information about long-term adoption increased adoption, particularly when that information shows that production gains have been achieved.

In the wake of the global food crisis of 2007–08 and additional price spikes since then, greater attention has been given to the welfare impact of food price increases in developing countries. The standard approach in this type of analysis, proposed by Deaton (1989), is based on income and expenditure data from household surveys. Given the widespread use of this method, it is important to revisit the assumptions behind it and examine the sensitivity of results to those assumptions. In this paper, we explore the distributional impact of higher maize, rice, and food prices in Ghana and analyze the robustness of those results to changes in several key assumptions. The results suggest that higher maize and rice prices have a relatively modest short-term impact on national poverty but significant effects on specific groups of households. As expected, urban households lose from higher grain prices, but a surprisingly large share of rural households also lose because they are net buyers. The results also suggest that the current policy of protecting domestic rice producers with an import tax does not contribute to national poverty reduction, in spite of the fact that rice growers tend to be poor. If we relax the assumption that households do not respond to the higher prices, the effects are more positive or less negative, but only modestly so. On the other hand, if we relax the assumption that producer and consumer prices rise by the same proportion, and instead assume a constant marketing margin, the results change substantially. Because producer prices now rise by a larger proportion than consumer prices, the impact of higher prices is much more positive. These findings highlight the need for more research on the effect of price spikes on marketing margins.

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.

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.

The good practice guidelines - which form the basis of an interactive policymaker's tool kit included on a CD accompanying the book - relate not only to the more focused problem of encouraging increased fertilizer use by farmers, but also to the broader challenge of creating the type of enabling environment that is needed to support the emergence of efficient, dynamic and commercially viable fertilizer marketing systems."--Jacket.

Household welfare effects of changes in rural livelihoods and their diversity is the central theme of this argument. Inter- and intra-livelihood diversification dynamics and effects on choice and intensity of participation in farm and nonfarm activities have been analysed using a three-period panel dataset on 464 households located in 8 villages of two distinct geoeconomic and agroecological zones of Ghana. This research is situated within the debate of whether or not the agriculture-led rural poverty reductionrenaissance is pragmatic in terms of both analytical and policy thinking of rural economic development. Almost every conclusion reached depends on isolation or proximity to "national capital, anti agro-productive potential of study area under rain- fed conditions. First of all, the notion of a shift from farm to nonfarm oriented rural livelihoods is rather a hyperbole. Quality of human capital, access to other productive assets, price and income risk sensitivity are the most important determinants of choice of, and returns to rural livelihood activities. Second, in high agro-potential zones, both farm and nonfarm oriented livelihood strategies produce similar welfare outcomes. Third, concerning diversification within agriculture, resource allocation to high-value crops enhances household food security in high agro- productive potential zones. Fourth, farm productivity is decreasing in pluriactivity, suggesting that returns to nonfarm labour supply must more than offset the value of productivity loss from agriculture if a household is to maintain a given level of welfare. Finally, neither farm nor nonfarm productivity was responsible for rural poverty exit in the 2000s; spatial location of household, living in a female headed household, human capital quality and rural - urban linkages through urban social network capital were the drivers of poverty exit. So, 'livelihood-led poverty reduction policy thinking' appears more pragmatic than a sectoral view of rural development policy and practice.

New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.
