This is the first volume on the proceedings of the national conference on ‘Water for Food and Environment’, which was held from June 9–11, 2009 at the Bandaranaike Memorial International Conference Hall (BMICH). The volumes two and three have been produced as separate documents of this report series. In response to a call for abstracts, 81 abstracts were received from government institutes dealing with water resources and agriculture development, also from universities, other freelance researchers and researchers from the International Water Management Institute (IWMI).Forty Seven of the eighty-one abstracts that were submitted were accepted for compiling full papers.In the past couple of years the sharp increase in food prices worldwide has raised serious concerns about food security, especially in developing countries. To effectively address these concerns a holistic approach is required that encompasses improved agricultural water productivity, adaptation to climate change, targeted and appropriate institutional and financial measures, and a consideration of environmental issues. The main purpose of the conference was to share experiences in these areas and to find opportunities to improve farmers’ incomes and food production, and to promote environmentally sustainable practices in Sri Lanka in the face of growing water scarcity and the challenges of climate change.

A barragem subterrânea é uma técnica de captação de água de chuva que tem contribuído efetivamente com a democratização do acesso à água para a agricultura familiar, em áreas dependentes de chuva, no Nordeste brasileiro. O presente trabalho tem como objetivo mostrar as experiências de duas famílias agricultoras com barragem subterrânea, na região do Sertão do Araripe, no Estado de Pernambuco, visando a estimular a multiplicação desta tecnologia no meio rural do semiárido. Foi realizado um monitoramento em duas propriedades, no município de Ouricuri, PE, no agrícola novembro/2006 - maio/2007, onde se acompanhou as características físicas e químicas do solo; as culturas plantadas; e o manejo dos respectivos agroecossistemas. Para se obter informações gerais sobre as propriedades e as famílias, foi elaborado e aplicado um questionário. As experiências das duas famílias demonstraram que a barragem subterrânea tem transformado um quadro de adversidade em múltiplas potencialidades; é, sem dúvida, uma das alternativas que em conjunto com outras tecnologias de captação de água, vem viabilizando a produção de água para obtenção de alimentos, o que tem resultado na valorização da cidadania, consequentemente na qualidade de vida das famílias.

Objective: To study whether eating or physical-activity (PA) habits differ between obese and non-obese monozygotic (MZ) co-twins independent of genetic effects. Methods: Rare MZ pairs discordant for obesity (n=14, body mass index difference 5.2±1.8 kg m–2) and weight-concordant control pairs (n=10, 1.0±0.7 kg m–2), identified through a population-based registry of 24–28-year-old twins (n=658 MZ pairs), completed 3-day food and PA diaries and eating behavior questionnaires. Each twin was asked to compare his/her own eating and PA patterns with the co-twin's behavior by structured questionnaires. Accuracy of energy intake was validated by doubly labeled water. Results: Non-obese co-twins consistently reported that their obese twin siblings ate more food overall, consumed less healthy foods and exercised less than the non-obese co-twins do. However, no differences in energy intake (9.6±1.0 MJ per day vs 9.8±1.1 MJ per day, respectively) in the food diaries or in the mean PA level (1.74±0.02 vs 1.79±0.04, respectively) in the PA diaries were found between obese and non-obese co-twins. A considerable underreporting of energy intake (3.2±1.1 MJ per day, P=0.036) and overreporting of PA (1.8±0.8 MJ per day, P=0.049) was observed in the obese, but not in the non-obese co-twins. Conclusions: On the basis of rare MZ twin pairs discordant for obesity, the co-twin assessments confirmed substantial differences in eating and PA behavior between obese and non-obese persons. These may be overlooked in population studies using food and PA diaries because of considerable misreporting by the obese.

The particular effect of 4 kinds of amino acid and peptide-rich food material (APRM) containing different charged amino acid contents on the gelatinization and retrogradation behavior of potato starch granules and on the water-vaporization behavior was analyzed by differential scanning calorimetry, rapid viscoanalysis, x-ray diffractometry, thermal gravimetry-differential thermal analysis, and pulsed NMR. APRM with a high-charged amino acid content produced unique gelatinization and retrogradation behavior in terms of an elevated gelatinization temperature, reduced viscosity, higher setback, and lower retrograded starch melting enthalpy. The recovered x-ray diffraction intensity decreased with increasing charged amino acid content. APRM with high-charged amino acid content could provide an improved paste having easy vaporization of external water in the swollen starch granules due to the reduced swelling.
