Weather reasons for adapting
Changes in land use and crop management
a) More erratic rainfall
- introduction of new, higher yielding crop varieties of maize, beans
b) ↘ overall rainfall (88%)
and tomatoes
c) ↗ amount of rainfall (39%)
d) more frequent droughts (71%)
- switching to disease resistant varieties of cassava, bananas and
e) earlier start of the rains 77%)
maize
f) Later start of rains (65%)
Drivers
• Availability of high yielding varieties
more resistant to pest and diseases
• More profitable market prices.
• Less productive land

Editor's Notes
Nos encontramos con el modelo de los cuatro países y se asigna el resultado (en este caso las diferencias entre la producciones actuales y futuras (2020) la producción de frijol) para Centroamérica.Como podemos ver, hay zonas donde la producción se reducirá drásticamente, mientras que otros están mejorando su potencial de producción. Los cambios ya descritos en las condiciones del clima y sus interacciones con las condiciones de ubicación específica determinaran la producción del cultivo. El estrés por calor, la sequía y las altas temperaturas en noche son los principales culpables de estos resultados. Esto es ampliamente sostenido por evidencia científica. Algunas de las conclusiones generales son:Frijol:Temperaturas> 28/18 C (día / noche) decrecimiento en la producción de biomasa, seed-set, el numero y tamaño de las semillas (menos vainas por planta, menos semillas por vaina, peso menor en las semillas)Niveles elevados de CO2 también decrece seed-setNiveles elevados de CO2 aumentaron la biomasa, pero los beneficios de los niveles elevados de CO2 disminuye con aumento de las temperaturas maíz:La tensión alta temperatura disminuye la polinización y la producción de semillas de maíz, causada principalmente por la disminución en la viabilidad del polen y receptividad del estigmaLa tensión alta temperatura disminuye la semilla-set y los números del núcleo por planta.La tensión alta temperatura también afecta negativamente la calidad del núcleo y la densidad (proteínas, enzimas)Etapas reproductivas (el desarrollo del polen, floración, llenado de los granos antes de tiempo) son relativamente más sensibles a la sequía, la sequía disminuye el número y el peso seco del núcleo. El maíz necesita 50% del agua en el período de10 días antes y 20 días después de la floración inicial. A pesar de subrayar lo suficiente la temperatura del agua afecta el desarrollo del polen.El estrés hídrico reduce el número y tamaño de granos.Las temperaturas más altas en la noche significa mayores pérdidas de la respiración por lo tanto la pérdidas de biomasa y de rendimiento.Con los resultados DSSAT ahora podemos identificar los diferentes tipos de ámbitos de intervención en la región (siguiente diapositiva)

Scaling up climate-smart agriculture: investment needs from innovation to implementation at scale. The set of sustainable agricultural practices that can improve adaptation, mitigation and livelihoods is highly diverse, varying by region and farming system. Many such practices are already well-known and others are yet to be invented or brought into general awareness. The process by which sustainable agricultural practices are taken up in specific farm regions and commodity sectors will be idiosyncratic, controlled by factors such as type and level of investment, availability of relevant knowledge and infrastructure, and the institutional and policy context. The type and amount of public and private sector investment varies country to country although, in general, investment in agriculture is low in low-income countries and higher in wealthier countries (where selection of agricultural practices is driven by a complex mixture of policy and market signals). The role of farmers’ organizations and agribusinesses is also highly variable by country and region. This schematic depicts the general sequence of investments, transitions and outcomes on the path to widespread adoption of agriculture practices that achieve adaptation, mitigation and livelihood objectives. Each phase in this general sequence has distinct incentives, knowledge requirements, risk tolerances, success metrics and expectations about return on investment. The purpose of this conceptual framework is to challenge funders, researchers, practitioners and other actors to clearly understand the precursors, partnerships and institutions required for investments to result in broad uptake of sustainable practices. It can also be used by those currently operating in one or more of these phases to clarify their role, objectives, progress and likely outcomes. Major phases include: (1) Innovation / identification of sustainable practices through adaptive farmer-driven research designed to achieve robust understanding of biophysical and socio-economic dynamics and outcomes relevant to incomes and environmental services. (2) Pre-investment (eg, climate finance, agricultural development funds) focused on ”real world” testing and operationalizing of sustainable practices through public-private partnerships designed to understand risks (eg, ROI lag time), barriers (eg, land tenure, subsidies) and necessary institutions (eg, managing financial flows, Extension) and infrastructure (eg, seed systems, monitoring). (3) Implementation of sustainable agricultural practices at scale, based on robust ROI, and establishment of public and private sector institutions to build capacity (eg, local farm associations and agribusinesses), provide oversight (eg, quality control for implementation and financing) and manage risk (eg, insurance or safety net programs), coupled with harmonization of the policy context (eg, re-orientation of subsidy programs). To meet urgent new challenges, stronger institutional mechanisms are needed (eg, to mitigate risks associated with innovation) and the research enterprise must evolve much more rapidly and develop better connectivity across research institutions, Extension and farmers (eg, through mandates for farmer-oriented research).
