Climate and political effects on agriculture: Empirical evidence from SSA

International Studies of Economics, EarlyView.
Abstract The most of Sub‐Saharan African (SSA) countries have been affected by climate change and food insecurity problems due to the reduction of production and productivity of cereal crops in the continent. The purpose of this research was to examine the short‐run and long‐run effects of climate change on agricultural productivity in 24 selected SSA ...

Toward better targeting of mitigation measures for reducing phosphorus losses from land to water: Andrew Sharpley's legacy in Norway and Sweden

Journal of Environmental Quality, EarlyView.
Abstract Nordic agriculture faces big challenges to reduce phosphorus (P) loss from land to water for improving surface water quality. While understanding the processes controlling P loss and seeking for P mitigation measures, Norwegian and Swedish researchers have substantially benefited from and been inspired by Dr.

Utility of near‐surface phenology in estimating productivity and evapotranspiration across diverse ecosystems

Journal of Environmental Quality, EarlyView.
Abstract Agroecosystems, which include row crops, pasture, and grass and shrub grazing lands, are sensitive to changes in management, weather, and genetics. To better understand how these systems are responding to changes, we need to improve monitoring and modeling carbon and water dynamics.

Selection for drought resistance in maize

, 1978
[ES] En Galicia, donde el maíz (Zea mays L.) es el cultivo de verano más importante, hay normalmente un periodo seco de unas cuatro o cinco semanas hacia la mitad del verano. Diversas poblaciones y líneas puras fueron ensayadas en condiciones de sequía de 1975 a 1978 en la Misión Biológica de Galicia (Pontevedra, España).

Armed Conflict and Livestock Species Choices in Northern Nigeria: Evidence From Panel Data Analysis

Journal of International Development, EarlyView.
ABSTRACT This study examines how armed conflict influences livestock species choices among households in northern Nigeria, a region with livelihoods largely dependent on livestock keeping. Using household panel survey data with global georeferenced conflict data, this study observes significant trends in livestock ownership patterns from 2010 to 2016 ...

A Typology of Malian Farming Households

Journal of International Development, EarlyView.
ABSTRACT Effective agricultural and rural development policies require a solid understanding of similarities and differences among farm systems. However, in many developing regions, the complexity and diversity of these systems are not well documented yet. In response, this study is aimed at developing a typology of Malian farming households.
