Does Intensive Tillage Enhance Productivity and Reduce Risk Exposure? Panel Data Evidence from Smallholders’ Agriculture in Ethiopia

This study analyses the impact of intensity of tillage on wheat productivity and risk exposure using panel household-plot level data from Ethiopia. In order to control for selection bias, it estimates a flexible moment-based production function using an endogenous switching regression treatment effects model. The result shows that tillage has a complementary impact on productivity and risk exposure.

Cropping system diversification, conservation tillage and modern seed adoption in Ethiopia: Impacts on household income, agrochemical use and demand for labor

The type and combination of sustainable agricultural practices (SAPs) adopted have a significant effect on agricultural productivity and food security. This study develops a multinomial endogenous switching regression model of farmers' choice of combination of SAPs and impacts on maize income and agrochemicals and family labor use in rural Ethiopia.

Integrating soil science into agricultural production frontiers

This paper integrates soil science variables into an economic analysis of agricultural output among small-scale farmers in Kenya's highlands. The integration is valuable because farmers’ choice of inputs depends on both the status of the soil and socioeconomic conditions. The study uses a stochastic production frontier in which the individual farm's distance to the frontier depends systematically on individual factors.

The impact of shadow prices and farmers' impatience on the allocation of a multipurpose renewable resource in Ethiopia

In a mixed farming system in which farmyard manure (FYM) is considered an important multipurpose renewable resource that can be used to enhance soil organic matter, provide additional income and supply household energy, soil fertility depletion could take place within the perspective of the household allocation pattern of FYM. This paper estimates a system of FYM allocation regressions to examine the role of returns to FYM and farmers’ impatience on the propensity to allocate FYM to different uses.

Climate Change and Total Factor Productivity in the Tanzanian Economy

The paper analyses the economic impacts of climate change-induced adjustments on the performance of the Tanzanian economy, using a country-wide CGE model. The general equilibrium framework enables comparison of the effects of climate change to the overall growth of the economy, as responsiveness to shocks is likely to depend on the macroeconomic structure of the economy.

Formal microlending and adverse (or non-existent) selection: A case study of shrimp farmers in Bangladesh

Microcredit schemes have become a popular means of improving smallholders’ access to credit and making long term investment possible. However, it remains to be explored whether the current microcredit schemes are more successful than earlier formal small scale lending in identifying successful borrowers. We studied shrimp farming in a rural region in Bangladesh where formal microlending is well established, but where more expensive informal microlending coexists with the formal schemes.

Importance of Irrigated Agriculture to the Ethiopian Economy: Capturing the direct net benefits of irrigation

Irrigation development has been identified as an important tool to stimulate economic growth and rural development, and is considered as a cornerstone of food security and poverty reduction in Ethiopia. While a lot of effort is being exerted towards irrigation development, little attempt is being made to quantify the contribution of irrigation to national income. This study is an attempt in that direction by quantifying the actual and expected contribution of irrigation to the Ethiopian national economy for the 2005/2006 and 2009/2010 cropping seasons using the adjusted net gross margin analysis.

The Effect of Ambiguous Risk and Coordination on Farmer´s Adaptation to Climate Change-A Framed Field Experiment

The risk of losses of income and productive means due to adverse weather can differ significantly among farmers sharing a productive landscape, and is of course hard to estimate, or even “guesstimate” empirically. Moreover, the costs associated with investments in reduced vulnerability to climatic events are likely to exhibit economies of scope. We explore the implications of these characteristics on farmer's decisions to adapt to climate change using a framed field experiment applied to coffee farmers in Costa Rica. As expected, we find high levels of risk aversion, but even using that as a baseline, we further find that farmers behave even more cautiously when the setting is characterized by unknown or ambiguous risk (i.e. poor or non-reliable risk information). Secondly, we find that farmers, to a large extent, coordinated their decisions to secure a lower adaptation cost, and that communication among farmers strongly facilitated coordination.

Nudging Boserup? The impact of fertilizer subsidies on investment in soil and water conservation

The new fertilizer subsidies in Sub-Saharan Africa are intended to increase agricultural production and ensure fertilizer market development. Fertilizer adoption requires complementary inputs such as investment in soil and water conservation for efficient and optimal nutrient uptake, and many fertilizer subsidy programmes implicitly assume that fertilizer subsidies crowd in such investments. The present study, therefore, evaluates the impact of fertilizer subsidies on the provision of soil and water conservation efforts in Ghana.

Agricultural Investment and Productivity - Building Sustainability in East Africa

Agricultural Investment and Productivity provides a deep and systematic look at the opportunities for and constraints to investments in sustainable agriculture in East Africa, offering important insights into what works and how to analyze agricultural investments in one of the poorest regions of the world. The book critically examines the reasons behind East Africa's stagnant agricultural productivity over the past forty-five years, using the primary lens of investments in fertilizers, seeds, and sustainable land management technologies, These investments have a tremendous impact on production volume, ultimately affecting the income of millions of families throughout the region.

Climate Change and Total Factor Productivity in the Tanzanian Economy: A Computable General Equilibrium Analysis

The paper analyses the economic impacts of climate change-induced adjustments on the performance of the Tanzanian economy, using a country-wide CGE model. The general equilibrium framework enables comparison of the effects of climate change to the overall growth of the economy, as responsiveness to shocks is likely to depend on the macroeconomic structure of the economy.

Impacts of the Productive Safety Net Program in Ethiopia on livestock

We evaluated the impacts of the Ethiopian Productive Safety Net Program (PSNP) on rural households' holdings of livestock and forest assets/trees. We found no indication that participation in PSNP induces households to disinvest in livestock or trees. In fact, households that participated in the program increased the number of trees planted, but there was no increase in their livestock holdings.

Sustainable Development Innovation Brief #7

"The contribution of sustainable agriculture and land management to sustainable development" - This brief discusses the potential for sustainable agriculture to contribute towards sustainable development with a particular focus on developing countries. It briefly describes different sustainable agricultural practices and the extent of their adoption, identifies constraints to their further adoption, and presents some actions and policy options that could accelerate the widespread adoption of sustainable agricultural practices.
