そのフィールドを詳しく見てみましょう（読みやすくするために改行を追加しています）

abstract = {Past, current and projected future population growth is outlined.
            Barring a calamitous pandemic, a further increase in the world's population
            from 7 to between 8.8 and 10 billion by mid-century is unavoidable.
            This increase is driven by high fertility in sub-Saharan Africa
            whose population is forecast to more than double in the next 40 years
            and by a modest rise of 23 % in Asia's huge population.
            Beyond mid-century, the range of plausible demographic destinations widens;
            much depends on fertility rates in the next few decades because
            they will determine the number of potential reproducers in
            the second half of the century.
            Vigorous promotion of family planning, particularly in Africa,
            is crucial to achievement of population stabilisation.
            Unchanged fertility implies a global population of 25 billion
            by the end of the century.
            In the next few decades the contribution of human population
            growth to global environmental change is moderate,
            because nearly all growth will occur in poor countries
            where consumption and emission of greenhouse gases is low.
            The implications for food production,
            and thereby water consumption, are greater.
            Much of the future need for food will be driven by increased
            numbers rather than changing diets.
            Loss of bio-diversity and natural habitats,
            degradation of fragile eco-systems due to over-exploitation

LaTeX がファイルから%フィールドの内容を読み取っているときにその記号に遭遇すると、その記号によって行の残りの部分がコメントに変換され、フィールドの末尾の閉じ中括弧が認識されないため、エラーが発生します。abstract.bbl%}

それが原因となり

エラー。

解決策は、%抽象フィールド内の符号をにエスケープすることです\%。

ほとんどの参考文献スタイルではフィールドを無視するため、ファイルからフィールドを完全にabstract削除する方がよいかもしれません。.bib（これはBiberによって即座に実行できます。biblatex/biber 使用時に bib 入力フィールドのパーセント記号でエラーが発生する、しかしそれは多くのファイルからフィールドを.bib完全に直接削除する方がよいでしょう。) 抽象が必要な場合は、理論的には%sをその場でエスケープすることが可能です。要約内の「%」文字で biber が詰まるのを防ぎますか?。
