Fragility, Conflict, and Migration

december, 2022
United States of America

Fragility, Conflict, and Migration addresses challenges to livelihood, food, and climate security faced by some of the most vulnerable populations worldwide. The Initiative focuses on building climate resilience, promoting gender equity, and fostering social inclusion. It forms part of CGIAR’s new Research Portfolio, delivering science and innovation to transform food, land, and water systems in a climate crisis.

Perspectives on aquaculture's contribution to the Sustainable Development Goals for improved human and planetary health

december, 2022
Global

The diverse aquaculture sector makes important contributions toward achieving the Sustainable Development Goals (SDGs)/Agenda 2030, and can increasingly do so in the future. Its important role for food security, nutrition, livelihoods, economies, and cultures is not clearly visible in the Agenda 21 declaration. This may partly reflect the state of development of policies for aquaculture compared with its terrestrial counterpart, agriculture, and possibly also because aquaculture production has historically originated from a few key hotspot regions/countries.

Understanding smallholder irrigation in Sub-Saharan Africa: results of a sample survey from nine countries

december, 2022
Global

Smallholder irrigation is emerging as a development priority in Sub-Saharan Africa. Based on a survey of 1554 smallholders from nine countries, this paper compares rainfed farming with gravity-flow, manual-lift and motor-pump irrigation. Motor-pump-irrigation farmers reported the highest net value added per acre and per family worker, with gravity-flow and manual-irrigation farmers earning marginally more than rainfed-only farmers.

Climate variability indices for ecological and crop models in R: the climatrends package

december, 2022
Global

Abiotic factors play an important role in most ecological and crop systems that depend on
certain levels of temperature, light and precipitation to initiate important physiological events
(Schulze et al., 2019). Understanding how these factors drive the physiological processes is
a key approach to provide recommendations for adaptation and biodiversity conservation in
applied ecology studies. The package climatrends aims to provide the methods in R (R Core
Team, 2020) to compute precipitation and temperature indices that serve as input for climate

Miracle seeds: Biased expectations, complementary input use, and the dynamics of smallholder technology adoption

december, 2022
United States of America

To fully benefit from new agricultural technologies like improved seed varieties, significant investment in complementary inputs such as fertilizers and pesticides, and practices such as systematic planting, irrigation, and weeding are also required. Farmers may fail to recognize the importance of these complements, leading to unsatisfactory crop yields and outputs and, eventually, dis-adoption of the variety.

Health impacts of smoke exposure in South America: increased risk for populations in the Amazonian Indigenous territories

december, 2022
Global

Smoke particulate matter emitted by fires in the Amazon Basin poses a threat to human health. Past research on this threat has mainly focused on the health impacts on countries as a whole or has relied on hospital admission data to quantify the health response. Such analyses do not capture the impact on people living in Indigenous territories close to the fires and who often lack access to medical care and may not show up at hospitals. Here we quantify the premature mortality due to smoke exposure of people living in Indigenous territories across the Amazon Basin.
