Abstract Knowing where, when, and how much rice is planted harvested crucial information for understanding the effects of policy, trade, global technological change on food security. We developed RiceAtlas, a spatial database seasonal distribution world’s production. It consists data planting harvesting dates by growing season estimates monthly production all rice-producing countries. Sources used include regional databases, national publications, online reports, expert knowledge. Monthly...
Abstract Good access to resources and opportunities is essential for sustainable development. Improving access, especially in rural areas, requires useful measures of current the locations where these are found. Recent work has developed a global map travel times cities with more than 50,000 people year 2015. However, provision will differ across broad spectrum settlements that range from small towns megacities, this settlement sizes should also be measured. Here we present suite nine...
Changes in the agriculture sector are essential to mitigate and adapt climate change, meet growing food demands, improve livelihoods of poor smallholder producers. What agricultural strategies needed these challenges? To what extent there synergies among strategies? This paper examines issues for producers Kenya across several agroecological zones. Several practices emerge as triple wins, supporting adaptation, greenhouse gas mitigation, profitability goals. In particular, integrated soil...
One major challenge in applying crop simulation models at the regional or global scale is lack of available gridded soil profile data. We developed a 10-km resolution dataset, 2 m depth, compatible with DSSAT using SoilGrids1km. Several physical and chemical properties required by were directly extracted from Pedo-transfer functions used to derive hydraulic properties. Other parameters not SoilGrids1km estimated HarvestChoice HC27 generic profiles. The newly dataset was evaluated different...
Most business-as-usual scenarios for farming under changing climate regimes project that the agriculture sector will be significantly impacted from increased temperatures and shifting precipitation patterns. Perhaps ironically, agricultural production contributes substantially to problem with yearly greenhouse gas (GHG) emissions of about 11% total anthropogenic GHG emissions, not including land use change. It is partly because this tension Climate Smart Agriculture (CSA) has attracted...
Crop modelling has the potential to contribute global food and nutrition security. This paper briefly examines history of crop by international research centres CGIAR (formerly Consultative Group on International Agricultural Research but now known simply as CGIAR), whose primary focus is less developed countries. Basic principles building up a Genotype × Environment Management Socioeconomic (G E M S) paradigm, are explained. Modelling contributed better understanding performance yield gaps,...
Abstract Crop improvement efforts aiming at increasing crop production (quantity, quality) and adapting to climate change have been subject of active research over the past years. But, question remains ‘to what extent can breeding gains be achieved under a changing climate, pace sufficient usefully contribute adaptation, mitigation food security?’. Here, we address this by critically reviewing how model‐based approaches used assist activities, with particular focus on all CGIAR (formerly...
Climate change poses a greater threat for more exposed and vulnerable countries, communities social groups. People whose livelihood depends on the agriculture food sector, especially in low- middle-income countries (LMICs), face significant risk. In contexts with gendered roles agri-food systems or where structural constraints to gender equality underlie unequal access resources services constrain women’s agency, local climate hazards stressors, such as droughts, floods, shortened...
Abstract Climate‐smart agriculture (CSA) is an approach for transforming and reorienting agricultural systems to support food security under climate change. Few studies, however, quantify at the national scale CSA's economic effects or compare CSA input‐intensive technologies, like fertilizer irrigation. Such quantification may help with priority setting among competing investment options. Our study uses integrated biophysical modeling contrast economywide of (integrated soil fertility...
