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 development of a fertilizer market. Fertilizer adoption requires complementary inputs, such as investment in soil and water conservation (SWC), for efficient and optimal nutrient uptake, and many fertilizer subsidy programs implicitly assume that fertilizer subsidies crowd in such investments.

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.

Investments in Land Conservation in the Ethiopian Highlands: A Household Plot-Level Analysis of the Roles of Poverty, Tenure Security, and Market Incentives

Land degradation is a major problem undermining land productivity in the highlands of Ethiopia. This study explores the factors that affect farm households’ decisions at the plot level to invest in land conservation and how much to invest, focusing on the roles of poverty, land tenure security, and market access. Unlike most other studies, we used a double-hurdle model in the analysis with panel data collected in a household survey of 6,408 plots in the Amhara region of Ethiopia.

The Bioeconomics of Conservation Agriculture and Soil Carbon Sequestration in Developing Countries

Improving soil carbon through conservation agriculture in developing countries may generate some private benefits to farmers, as well as sequester carbon emissions, which is a positive externality to society. Leaving crop residue on the farm has become an important option in conservation agriculture practice. However, in developing countries, using crop residue for conservation agriculture has the opportunity cost of feed for livestock.

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.

Fast Track Land Reform and Agricultural Productivity in Zimbabwe

The author investigated the Zimbabwean Fast Track Land Reform Program’s (FTLRP) impact on the agricultural productivity of its beneficiaries. The data revealed significant differences between beneficiaries and a control group of communal farmers in household and parcel characteristics and input usage.

Determinants of Soil Capital

Explaining soil capital facilitates a better understanding of constraints and opportunities for increased agricultural production and reduced land degradation. The diversity in farmers’ soil capital, production strategies, and general farming systems (including conservation investments) points to the value of internalizing these aspects in the formulation of the government’s policies and extension advice on sustainable agriculture.

Production Function Analysis of Soil Properties and Soil Conservation Investments in Tropical Agriculture

This paper integrates traditional economic variables, soil properties, and variables on soil conservation technologies to estimate agricultural output among small-scale farmers in Kenya’s central highlands. The study finds that integrating traditional economics and soil science is invaluable, especially as omitting measures of soil capital can cause omitted-variable bias. The central policy implication is that while fertilizers are generally beneficial, their application is a complex art, and more is not necessarily better.

Market Imperfections and Farm Technology Adoption Decisions: A Case Study from the Highlands of Ethiopia

This examination of the impacts of market and institutional imperfections on technology adoption found that Ethiopian farmers’ decisions to adopt fertilizer significantly and negatively depended on whether they also adopted soil conservation, but not vice versa. Market imperfections were significant factors in explaining variations in decisions to adopt farm technology, such that relieving market imperfections could increase adoption of farm technologies.

Are the Poor Benefiting from China's Land Conservation Program?

This paper studies the impact of the largest conservation set-aside program in the developing world, China’s Grain for Green program, on poverty alleviation in rural areas. Based on a large-scale survey, we find that although poor households in rural China were not disproportionately targeted, they have benefited.

Land Conservation Policies and Income Distribution: Who Bears the Burden of our Environmental Efforts?

We analyze how land conservation policies affect income distribution looking at changes in wages and rents. Land conservation policies restrict the land for agricultural use. We study how these restrictions affect workers and landowners incomes. Aggregate rents rise when protected areas increase despite the reduction of land availability. Real wages decrease as a consequence of higher prices.
