<p>The pod and yield characteristics of <em>Moringa oleifera </em>plants grown in Ibadan (Rainforest vegetation), Nsukka (Forest-derived savannah vegetation) and Jos (arid derived savannah vegetation) were evaluated from 2007- 2009 to assess adaptability of the plant to climate change threats. The rainfall and temperature distribution in the three locations varied over the years. The <em>Moringa oleifera</em> plants grown at Ibadan had the greatest pod and seed yield followed by those at Nsukka and Jos in that order. The annual pod and seed production capacities of the plants differed significantly (p &lt; 0.05) in the different locations. The overall annual pod and seed production per location, including yield characteristics, did not differ significantly throughout the years of study. <em>Moringa oleifera</em> was therefore found to be a suitable crop adaptable to various environmental and climatic changes in Nigeria.</p>

Adverse Impacts

Malaysia is one of the highly vulnerable countries due to climatic changes. Here the changes in climate factors cause adverse impacts on agricultural sustainability and relevant livelihood sustainability. To adapt to these changes a prudent adaptation policy is very important. Several countries follow different adaptation policy based on their localized socioeconomic and geographical status. While defining its adaptation policy, Malaysia also needs to consider several crucial factors. This study discusses issues relevant to the farmers’ adaptation to climate change in Malaysia and also provides few recommendations that will help policy makers to prepare the agricultural adaptation policy for climate change

Abstract The evolution of climate during the seventy-year cycle (1946-2016) led to the shaping, in the region, of two parallel trends of the evolution of the soil cover: a) in the sense of aridization; b) in the sense of humidification. These are due to the contouring of an alternation of drought and humid and relatively damp years in the 11-year climate cycle. According to calculations, 5 of them are humid or relatively damp and 6 are dry or relatively dry. Research shows that the climatic environment in the phase of modification leads to the simultaneous development of processes of both aridization of several spaces and hydromorphism of other. This situation shows different stability of the soil cover components in the region to climate change under natural-anthropogenic chernozem conditions. This particularity of soil development is to be taken into account both in pedological studies and in the framework of Regional Strategies and Programs for Adaptation to Climate Change.

Species with restricted distributions make up the vast majority of biodiversity. Recent evidence suggests that Drosophila species with restricted tropical distributions lack genetic variation in the key trait of desiccation resistance. It has therefore been predicted that tropically restricted species will be limited in their evolutionary response to future climatic changes and will face higher risks of extinction. However, these assessments have been made using extreme levels of desiccation stress (less than 10% relative humidity (RH)) that extend well beyond the changes projected for the wet tropics under climate change scenarios over the next 30 years. Here, we show that significant evolutionary responses to less extreme (35% RH) but more ecologically realistic levels of climatic change and desiccation stress are in fact possible in two species of rainforest restricted Drosophila . Evolution may indeed be an important means by which sensitive rainforest-restricted species are able to mitigate the effects of climate change.

This article studies the economic profitability of the millet production in a context of adaptation to climatic changes by considering the techniques of adaptation to soil protection, namely, low wall girdles tree and half-moon in order to determine their impact on the economic profitability of the production of this cereal.The economic model of profitability developed by Gnanglé and al. [15] is used to analyze this effect. The data used in this paper is obtained from the ministry of agriculture of Niger (ECVM/A 2015) and consists of 3,985 households from two regions of Niger, namely, the Maradi and Diffa regions. The results show that the techniques of "belt of tree" and "half-moon" increase the economic profitability of the millet production and that the effects are, respectively, 0.19 and 0.054 in the two areas. The econometric results show that these techniques are profitable in both areas. Given the effectiveness of these techniques, this study suggests that producers increase these practices in order to mitigate the effects of climate change on the millet production in Niger. Lastly, the government must popularize these techniques and support their use for a better adaptation of agriculture in these zones to climate change.

This study was part of broader PhD research which investigated how access to, and use of, information enhances adaptation to climate change and variability in the agricultural sector in semi-arid Central Tanzania. The research was carried out in two villages using Rogers’ Diffusion of Innovations theory and model to assess the dissemination of this information and its use by farmers in their adaptation of their farming practices to climate change and variability. This predominantly qualitative study employed a post-positivist paradigm. Some elements of a quantitative approach were also deployed in the data collection and analysis. The principal data collection methods were interviews and focus group discussions. The study population comprised farmers, agricultural extension officers and the Climate Change Adaptation in Africa project manager. Qualitative data were subjected to content analysis whereas quantitative data were analysed to generate mostly descriptive statistics using SPSS.  Key findings of the study show that farmers perceive a problem in the dissemination and use of climate information for agricultural development. They found access to agricultural inputs to be expensive, unreliable and untimely. To mitigate the adverse effects of climate change and variability on farming effectively, the study recommends the repackaging of current and accurate information on climate change and variability, farmer education and training, and collaboration between researchers, meteorology experts, and extension officers and farmers. Moreover, a clear policy framework for disseminating information related to climate change and variability is required.
